A Guide for Watering Houseplants

A Guide for Watering Houseplants

Keeping indoor plants healthy requires learning how to water well—too much, and you might stress them out. Learn how to tell when indoor plants need more water and the best strategies to keep them healthy and hydrated.

When it comes to keeping your indoor plants alive, how you water them needs to be a key consideration.
 
Unlike plants in the natural world, those kept indoors will never get rained on. This means, as caretaker, that you are solely responsible for controlling their environment to help them thrive. However, knowing the watering needs of houseplants can get challenging, and many plant owners err on the side of providing too much or too little.
 
Here’s a guide to watering houseplants to help you keep yours healthy and thriving.
The Challenge of Watering Indoor Plants

When it comes to water needs, indoor plants are far from one-size-fits-all. Each plant’s water requirements depend on various factors, from its light exposure to the location in your house and the kind of material it is planted in.

For example, succulents need minimal water and quickly rot when given too much, while many tropical ferns struggle to grow if their foliage isn’t continuously moist. Plants in hanging baskets dry out far faster than those on the ground, and many indoor plants spend part of the year in a dormant phase that changes their water needs considerably.

In other words, if you want to figure out a watering strategy for your houseplants, you need to do the research to understand each variety’s specific requirements so you can best meet their needs.

How to Tell When Indoor Plants Need Water

The first step for watering houseplants is knowing when they need water to begin with. The easiest method is to gauge the soil’s moisture level. Stick your index finger into the potting soil about one inch (2cm) down. If the dirt feels dry to the touch, the plant likely needs more water.

It’s also possible to lift the pot to feel whether it seems heavy from wet soil or light and dried out. This works best if you first get a sense of how hefty the pot is immediately after watering.

Note that browning leaves and a drooping demeanor aren’t reliable signs that a plant needs water. Sometimes, these same symptoms occur when a plant is overwatered, and the roots are struggling to pull in enough oxygen.

Should You Water Houseplants From the Bottom?

While watering cans are the standard way to water houseplants, another method is to water pots from the bottom. This keeps plant roots hydrated without hurting their foliage above.

 First, make sure your plant is in a pot with drainage holes along the bottom. Set it on a saucer with a tall lip or any container large enough to hold the potted plant. Fill this container partway with water and place the pot in the middle.

Let it sit for at least ten minutes before touching the top of the soil. If it feels wet, the plant’s roots successfully drew up the moisture. If not, let it sit longer. Either way, make sure you move it or drain the container within an hour to ensure the roots won’t rot from sitting in water too long.

Note: Bottom watering won’t remove excess salts from the soil like top watering will. You can solve this problem by watering your houseplants from above at least once a month.

Ten Troubleshooting Tips to Water Indoor Plants Successfully

Don’t let your houseplants run into problems. Here are some proven strategies to ensure you water your indoor plants well.

1. Only Use Tepid Water

Hot or cold water straight from the tap will shock plant roots and potentially stunt them. Take your cue from rainwater and only use room temperature water for your houseplants.

2. Water Around the Whole Pot

Novice plant keepers often err by watering their plants in just one spot, which can starve half the roots of water in the long run. Take care to pour water around the whole pot so each part of the plant stays hydrated.

3. Avoid Using Treated Water

The water from your tap can include various additives, including chlorine, fluoride, and salts (if it’s softened). These compounds can affect plant health over time. Your best option is to water houseplants with filtered water, collected rainwater, or untreated well water.

4. Water Deeply and Less Frequently

As with outdoor plants, frequent light waterings encourages houseplants to develop shallow roots and makes them extra sensitive to any drought periods. You’ll promote better root growth in the long run by watering deeply and less often.

5. Choose the Right Sized Pot

One common mistake houseplant owners make is choosing pots based on their styling instead of size. Smaller pots dry out more quickly, which will stress the plant inside. Make sure you purchase the correct sized pot for your plant and scale up as it grows.

6. Pay Attention to Light Exposure

Even indoor light leads to evaporation, which means that houseplants that spend their time in bright spaces need more water than those in low-light conditions. Note whether your plant is drying out faster on sunnier days and water accordingly.

7. Water Soil, Not Foliage

One of the easiest ways to spread disease is by keeping plant leaves warm and wet, as it creates an ideal breeding ground for bacterial pathogens and fungal spores. A better choice is to use a watering can with a long spout to wet the soil directly so the foliage stays dry.

8. Track Humidity

Some plants, especially tropical varieties, require that their leaves and foliage stay relatively moist. This means you’ll need to mist them regularly to promote optimal growth. Consider keeping these plants somewhere with a relatively high moisture content, such as near a humidifier or in a steamy bathroom.

9. Consider the Seasons

Even indoor plants go through seasons of growth. They will require more water during flowering stages, but far less once they start conserving energy for colder months. Note what stage your plant is in and change your watering schedule to fit it.

10. Repot When Waterlogged

You may find that your plant’s soil never seems to dry out, no matter how carefully you water it. This might be due to overly compacted soil or clogged drainage holes that trap the water near the plant roots. Consider replanting stressed plants in fresh soil and a bigger pot with clear drainage holes.

Watering indoor plants doesn’t need to be stressful. So long as you take the time to research the water needs of what you’re growing, you can provide houseplants with the healthy environment they need to thrive.

Understanding Temperature for Plants

Understanding Temperature for Plants

If you want your plants to thrive, you need to pay attention to the temperature they live in. Learn how to determine what temperature your plants need both indoors and outside so you get the best results possible.

Plants are picky about their living conditions, and the wrong temperatures can make it hard for them to thrive. Understanding the role temperature plays in plant growth makes it easier to ensure your plants get the best start in life possible. Here’s what you need to know.

Istock
Plants, Temperature, and Photosynthesis

Temperature is considered second only to light as the most vital component for plant growth, and it’s a critical factor in photosynthesis. During this process, plants pull energy from the sun, which they transform into glucose to use as fuel. Temperature extremes on either end of the spectrum interfere with this process.

If the temperature drops too low, your plant may stagnate and die, especially if exposed to lots of cold water. Likewise, high temperatures will speed up plant respiration and can break down existing sugars, leaving the plant with little food to support further growth. This causes it to drop its leaves and become spindly.

Understanding Temperature Ranges

Temperature’s overall effect on plants varies based on many factors, including its sunlight exposure, elevation, temperature variation between day and night, the proximity to surrounding heat-retaining structures (like rocks and walls), and the moisture drainage levels in the soil.

Thankfully, plants are relatively resilient to most temperature fluctuations, especially between daytime and nighttime. In fact, flowering plants often do best with daytime temperatures between 70-80 degrees F (21- 26°C) but nighttime temperatures closer to 55-60 degrees F (12-15°C). These lower nighttime temperatures help the plant recover from moisture loss, which leads to longer-lasting flowers with more intense coloring.

Outdoor plants tend to handle temperature changes better than indoor ones. Here’s a general rule for the minimum temperatures most annual plants can handle outside.

However, each plant species has its own temperature requirements. When buying new plants, it’s important to research what maximum and minimum heat level they can best handle.

Indoor Temperatures for Plant Health

Growing plants indoors gives you more control over their environment, but this coddled environment means they can become more sensitive to temperature fluctuations over time. Thankfully they have a larger comfort range than most people do. People usually feel best in indoor temperatures between 72–82°F (22–27°C), but plants have a broader comfort temperature range of 58–86°F (8–30°C).

When choosing indoor locations for indoor plants, pay attention to potential temperature danger zones. These are places where the temperature can jump from extremes quickly, such as windowsills and drafty doorways. Long-term exposure to these spaces can stress your plants, so choose locations where the temperature won’t vary as much.

If your indoor plants show signs of stress, there are two primary options for promoting growth again. These include either increasing the available lighting (to promote photosynthesis) or decreasing the nighttime temperatures (to promote respiration).

Indoor Germination

While indoor plants will do best if you keep their temperature stable, the rules change slightly if you’re starting seeds for plants that will eventually move outdoors, like for a vegetable garden. In this case, you want to subtly mimic the variation of day and night temperatures so the plants don’t go into shock when planted outdoors.

It’s also possible to mimic the seasons indoors for plant germination. For example, many seeds need to be cold stratified before planting, meaning you need to keep the seeds in the refrigerator for several weeks to replicate winter temperatures before planting them in the “spring.”

Germination rates increase as the temperature goes up, but only to a point. Get it too hot indoors, and seedlings might suffer after sprouting. Some cool-season vegetables, such as broccoli and lettuce, require chillier temperatures between 55–70°F(13–21°C), while warmer weather plants like squash and tomatoes prefer to germinate in temperatures between 70–85°F (21–30°C).

The Importance of Outdoor Soil Temperature

If you’re growing plants outdoors, the soil temperature is a crucial factor in success. All soil microorganisms have optimal temperatures in which they operate, and ground that is too chilly or hot keeps them sluggish, which may negatively affect your plants.

You can measure the ground temperature with a soil thermometer to ensure you plant at the right time. For best results, use it in the early morning when the soil is coolest, and get the reading between one and three inches down in the ground. Take the temperature for three consecutive days and average the results for the most accurate reading.

If you need to warm the soil up quickly, covering it with dark mulch will attract sunlight and bring up the temperature within a few days. Plastic sheets work even better because the synthetic material holds heat in. You can also till the first few soil layers to bring it to the surface and promote excess water drainage that could be cooling it down.

Sometimes, waiting for the soil to warm isn’t realistic, and you need to get seeds in the ground fast. Here’s a closer look at the minimum and optimal soil temperature requirements for different plant varieties so you can assess when planting makes the most sense.

Is Your Temperature Wrong? Three Signs of Problems

Sometimes you might not notice problems with the temperature around your plants until you see signs of stress around them. Here are three ways plants express something is wrong with their growing conditions:

Note that each of these plant conditions could be caused by other problems unrelated to temperature. Observe the problem carefully and experiment with different changes until you see what makes an improvement.

Plant Lighting 101: What You Need to Know

Plant Lighting 101: What You Need to Know

All plants need light to survive, and too much or too little can cause them to suffer. Learn how to plan your outdoor planting around each plant’s lighting needs and the best ways to position indoor plants for success all year long.

When it comes to growing healthy plants, light exposure needs to be a key consideration. Too little light will lead to feeble growth, but too much can scorch sensitive leaves and hurt your plant over the long term. How much light is enough? Here’s a guide to understanding the light requirements for both indoor and outdoor plants.

Why Plants Need Light
All plants require lots of light exposure for photosynthesis. This natural process allows plants to harness energy from sunlight in order to transform carbon dioxide and water into glucose—a primary source of plant food that fuels long-term growth.

The more light available, the more energy a plant can harness, and the faster it will grow. However, this only holds true to a point. It’s possible to give growing things too much of a good thing and stress them out to the point of getting stunted or even dying. Some plants need six hours of sunlight per day, while others do better with less.

Here’s how to understand the requirements for both indoor and outdoor plants.

Lighting Needs for Outdoor Plants

The light requirements for outdoor plants are often indicated by the hours of sunlight they should be exposed to per day. When buying a new plant, look for a tag that includes one of these labels.

Full Sun

This label indicates the plant will thrive best with as much natural light as possible and need at least six hours of sun exposure per day. Drought tolerant perennials and most vegetables fall under this category. If you don’t have spots in your garden that stay sunny all day, prioritize places with lots of afternoon sun as it tends to be stronger than morning.

Partial Sun
Plants that fit into this category usually need about six hours of daily sunlight but also benefit from time in the shade. They typically do best with morning sun and some afternoon shade to protect from the scorching afternoon heat. Many flowering plants require partial sun conditions.
Partial Shade

This category represents plants that need four hours or less of direct sunlight (an hour and a half is ideal). Most will do best when planted in an east-facing garden bed that provides sunlight exposure in the morning and shade by midday.

Dappled Sun
This rare requirement refers to plants that need small amounts of sunlight while staying protected, similar to what they would get from the filtered light available under a tree. You can also shield these plants under a lightweight shade cloth.
Full Shade
While full shade plants still need some sunlight, they can’t handle more than three hours per day. They do well under larger plants and should be grown in the shadiest parts of your yard. Best of all, they typically require minimal maintenance once established.
A Note on Sun Levels

With outdoor plants, all sunlight is not equal. For example, direct sunlight along the equator is significantly more extreme than the same amount of light at locations closer to the poles. You’ll need to do some research about your outdoor conditions to determine whether to modify the sunlight recommendations for each variety.

Lighting for Houseplants

The lighting needs for houseplants vary significantly compared to outdoor plants. Indoor light strength is often measured by foot-candles, which refers to the light intensity of a unit of measure known as a candela.

– 200–500 foot-candles: Low-light, deep shade, unsuitable for most plants

– 500-1,000: Low-light but bright enough to read by, suitable for some shade plants

– 1,000-2,000: Bright, indirect sunlight that won’t produce a strong shadow

– 2,000-4,000: Direct light coming through windows, equal to about 40 percent of the midday sun

– 4,000-5,000: 50 percent of the midday sun, intense direct sunlight in a bright room

– 5,000+: Super bight, direct indoor light

Note that full sun outdoors comes in at about 10,000 foot-candles. This means that the darkest shade outdoors still tends to be brighter than what plants get from the sunniest window, so only the most shade-tolerant plants tend to thrive inside without supplemental light.

You can also orient indoor plants based on the directions your windows face.

– North-facing windows: Tend to have the weakest light, may work for shade plants but likely will not grow anything in the winter

– South-facing windows: Often have the strongest light intensity and offer consistent all-day light

– East-facing windows: Benefit most from the morning sun, best for plants that need moderate light exposure

– West-facing windows: Lots of strong afternoon and evening sun, suitable for most sun-loving plants

Proximity to windows makes a huge difference for indoor plants. Moving one just a few feet from a window can easily halve its light exposure, so make your décor decisions carefully.

How Much Light Does Your Plant Get?

Short of measuring your home’s foot-candle output, how can you tell how much light your plants are getting? One easy test is to hold your hand about a foot above a plain piece of paper. If you only see a faint shadow (or none at all), you have low light. A blurry or fuzzy shadow is a sign of medium-intensity light, and a crisp shadow indicates a strong, direct light source.

Signs Plants Need More Light

Your plants themselves will usually tell you whether they are getting enough light to thrive. Signs of too little light exposure include long, spindly stems and yellowing or dropping leaves. This is called etiolation, and it means that the plant is straining to grow towards the available light, but it isn’t strong enough for the plant to photosynthesize properly.

This problem is easy to fix by moving plants into direct sunlight or adding a supplement light source such as a grow light. Even a few hours of exposure a day to artificial light can transform a spindly plant and help it grow more robust.

In contrast, pale leaves or those with crispy browning sections may be getting burned from too much light. You may want to provide shade or move the plant somewhere with less direct light exposure.

Understanding the lighting needs for different plants will help you ensure you give them what they need to thrive. Do your research now so you can place plants where they will best get their needs met for the healthiest garden possible.

A profusion of riotously-colored garden phloxes (Phlox paniculata) blooms lushly from summer through early fall, refreshing our hearts and minds with a gentle fragrance. You are likely to find hummingbirds and butterflies dancing among the flowers, as well as many beautiful birds, all lured by its nectar and refusing to leave the sea of blossoms, turning the garden into a fairyland. Bring garden phlox home and let these sweet-scented colorful fairies make your daily life dynamic and wonderful. 

Garden phlox, a perennial herb, is originally from the Mideast US and eastern Canada, where people call it many local names, such as summer phlox, fall phlox, or perennial phlox. It likes warm habitats where sunlight is abundant with some shade. Its flowers bloom in clusters on conical inflorescences with five symmetrical lobes, looking exquisite and smelling fragrant, all making it an important ornamental flowering plant. 

A Gardening Plant That Came Home With Flying Colors

In the early eighteenth century,  Europeans first discovered garden phlox’s potential. Garden phloxes were first shipped from Virginia to Europe, gradually gaining popularity in the early nineteenth-century British and mid-nineteenth century French markets. Later, many improved varieties of this plant found their way back into the US market. 

Garden phlox were briefly forgotten and left in obscurity from 1940 to 1980, but people rediscovered interest in it shortly after. Nowadays, thousands of differently shaped and richly colored varieties have been cultivated. 

The Color Palette of Your Garden

Garden phlox blossoms in a rich assortment of colors, including elegant white, passionate red, delicate yellow, lively orange, gentle purple, and adorable pink, etc. 

Horticulturists particularly prefer garden phlox, and have selected and cultivated many varieties for garden planting that boast a charming array of colors. Many such varieties have won the Royal Horticultural Society’s Award of Garden Merit, such as the white-and-purple alternately-colored Velvet Flame, the light-and-dark-pink confluently-colored Miss Pepper, and the uniquely lavender-ash-colored Grey Lady, among others.

The varieties are not only vividly colored but also charismatically named. There are Peppermint Twist, with a pink and white color combination, Sherbet Cocktail, with delicate alternate pink and yellow colors, and Ending Blue, with graceful white-striped violet flowers. All of these dynamic-looking blossoms exude captivating scents that make you feel you’ve fallen into a sweet fairyland dream. 

Garden Phlox in American Literature and Art

In 1916, famous American horticultural author Louise Beebe Wilder mentioned garden phlox in his first well-known book, My Garden. She wrote, “This plant is a native, and with true American perspicacity and enterprise has forged his way from magenta obscurity to the most prominent place in the floral world.”

American artist and naturalist Mary Vaux Walcott, known to the world through her watercolor paintings of wildflowers, is called the “Audubon of botany.” In 1934, she painted garden phlox, helping to popularize it. The collector of this original painting donated it to the Smithsonian American Art Museum in 1970, giving the public a chance to see this renowned art piece in person.

If you are interested in enjoying various garden phlox varieties, check out the Chicago Botanic Garden. 

The Chicago Botanic Garden is a huge 385-acre botanic museum, consisting of 26 sub-gardens with interlaced scenes, encompassing multiple lakes, islands, and forests. From 2001 to 2009, Chicago Botanic Garden conducted a periodical observational experiment on 78 varieties of garden phlox, and you can still see these delicate fairies around on a summer or early fall walk through the Garden. 

Can I Grow Garden Phlox Well?

Garden phlox is tenacious and strong. Provide its preferred temperature, soil, and water conditions, and with a little bit of care, you can enjoy its visual and olfactory double delight at home. 

Garden phlox likes warm, moist, well-ventilated environments. It loves basking in ample sunlight but also needs some shade in hot summers. Being intolerant of heat and drought, it requires frequent watering. Don’t water it from the top-down, nor let the water stand. It’s best to use loose, fertile, neutral, or alkaline sandy loam with good drainage. 

Prune off flowering sprays after buds sprout in the spring and after flowers are spent in the fall to promote more gorgeous blooming next year. Pay attention to prevent powdery mildew and root rot.

Clean Your Houseplants with These 6 Useful Tips

Clean Your Houseplants with These 6 Useful Tips

Houseplants do require some maintenance on a regular basis to thrive and grow. Keeping them healthy is easy with these expert tips. It’s important to keep the leaves clean so that your plants can breathe. Follow our tips for healthy, happy houseplants.

Just like the plants growing in your garden, your houseplants need regular maintenance too. When they spend their entire life indoors, plants tend to gather dust and other debris from the air. Some leaves will die and drop down into the pot, and flowers will also die once they’ve given you a magnificent show.

Here are some basic maintenance tips for houseplants that you should incorporate into your cleaning routine.

Remove Spent Flowers and Foliage

You spend time deadheading and pruning your garden plants, so you need to do the same for houseplants. Regular deadheading is important for flowering houseplants because it can encourage further flushes of flowers.

It’s also a good idea to remove any leaves and stems that are turning brown or are about to fall off. Remove any foliage that has fallen onto the soil in the pot as well, as this decaying plant matter may encourage pests and diseases.

You can also give your houseplants a light trim with a pair of garden pruners to keep them compact and shapely.

Dust Your Houseplants Regularly

Like everything else in your house, your plants will collect dust. Therefore, it’s important to remove this from the leaves. The leaves are your plant’s lungs and if they’re covered in dust, your plants will have trouble “breathing”.

For a quick dusting, you can use a feather duster but be very gentle as you don’t want to damage your plant. Don’t do this with ferns though as you may dislodge the spores into the air.

For delicate plants and those with furry leaves, you can just use a soft toothbrush to remove any dust on the leaves.

Wipe Down the Leaves for a Deeper Clean

It’s a good idea to periodically wipe down the leaves of your houseplants for a deeper clean and to remove any residue that’s settled there. This can be as simple as using a damp dishcloth.

Just place your hand under the leaf to support it and wipe down from the stem outwards. Remember to wipe the undersides of the leaves as well because this is where pests may hide.

For a more thorough clean, try mixing a little dish detergent with water and then wipe this mixture over the leaves. This approach works really well for houseplants with large leaves. However, it’s not the best if you have delicate plants such as ferns or African violets with furry leaves.

Also note that you should never use a leaf shine product on your houseplants. These products contain oils or waxes, which will clog up the pores in the leaves. As a result, your plants will be unable to breathe and eventually suffocate.

Give Your Plants a Shower

For delicate plants or those with furry leaves, you can actually give them a shower. After all, this is what your outdoor plants get every time it rains.

Remember to use tepid water. Your plants don’t like either hot or cold water. Placing them in the shower for a few minutes with the door closed also creates a little humidity. Most houseplants actually love this.

Make sure, when doing this, that the soil doesn’t wash away. You don’t want to clog up your drain with potting mix. To avoid this from happening you can:

After showering your plants, you should leave them to drain fully and make sure the leaves are almost dry if you’re placing your plants in a sunny spot. This is because if there’s water left on the leaves and the sun hits them, it could cause the leaves to burn.

Before placing your plants in the shower, make sure that the pot has drainage holes. This way, any excess water can easily drain out of the soil and won’t cause any water-logging for the roots. You might like to add some additional slow release fertilizer as most of the nutrients in the soil may have leached out with the water.

If you have plants in pots without drainage holes, such as succulents, do this instead:

This will avoid the water getting into the soil and drowning the roots.

Give Your Houseplants a Spell Outside in the Rain

If the weather is mild and you’re expecting a light shower of rain, you can place your houseplants outside for an hour or two. Rainwater is an amazing tonic for your plants and they will really appreciate it.

Therefore, if it’s not too hot or cold or windy, if you can, place your houseplants outside in the rain for a short time. Remember to let them drain before bringing them back inside.

Top Up the Potting MIX and Add Some Fertilizer

While you’re giving your houseplants a good clean, you might like to top up the potting mix as well. Over time, the mix will settle in the pot and this will lower the level of the mix. It’s perfectly fine to just top this up a little.

While you’re doing this, add a little slow-release fertilizer. These slow-release pellets will provide the roots of your plants with nutrients as and when they need it

On the other hand, if your plant has been in the same pot for a long time, you might want to consider repotting it into a larger pot. Most houseplants will really benefit from this and will put on a flush of new growth as a result.

If your plant has become very root bound, you should gently tease out the roots a little and you can even trim off any that are really long. Once your plant is in the new pot, it will grow new little roots that are better able to take up the nutrients and water in the soil.

Final Thoughts

Just like the plants growing in your garden, your houseplants need a little maintenance from time to time. You should trim off any spent flowers and remove any brown foliage.

Also, make sure that you regularly remove dust from the leaves of your plants to keep them growing healthy and strong.

And finally, consider repotting your plants every so often so that they can put on some lovely new growth. If you take good care of your houseplants, they’ll reward you with beautiful lush foliage and stunning flowers to brighten up your home.

How to Control Common Houseplant Pests

How to Control Common Houseplant Pests

There are a number of pests that can infect your houseplants from time to time. These are mostly sap-sucking insects and fairly easy to control. Have a look at these five different pests that might be infecting your houseplants and how you can easily control them.

Although pests on houseplants aren’t as prolific or common as the pests you might find on your plants outdoors, they do still occur. And when they do, you want to control them as quickly as you can to avoid any damage or them spreading to other plants.

Wherever possible, it’s a good idea to use organic controls for your houseplants to limit the amount of chemicals that you spray in your home. In saying that though, we’ll be discussing both eco-friendly controls as well as chemical controls so that you can have the choice.

Here are 5 common pests that you are likely to find on your houseplants.

1. Aphids

Although more common on your outdoor plants, aphids can make their way inside and feast on your precious houseplants. Aphids are sap-sucking insects that generally attack new growth. They’re quite small and can be green, black or gray in color.

You’ll usually find them on the undersides of leaves or on new flower buds. Because they tend to congregate in large clusters, they’re very easy to spot. Aphids also exude a sticky honeydew type substance that is easy to spot on the lower leaves.

If left uncontrolled, leaves and young stems will start to turn yellow and new growth will become distorted.

Treatment

Aphids are fairly easy to control with a spray made from dish detergent mixed with water in a spray bottle. Spray the plant liberally making sure to cover the aphids with the mixture. What this does is coat the aphids so that they die.

Leave the mixture on the plant for around 5 minutes and then wash it off. You can do this in the shower or even under some running water in the sink. You may have to repeat this a couple of times to ensure you’ve removed all the aphids.

If you need something a little stronger, you can use a proprietary product that contains pyrethrin or neem oil. You’ll usually find this in convenient spray bottles at your local garden center.

2. Mealybugs

Mealybugs, like aphids, are sap-sucking insects. They’re small, white and look slightly furry. Mealybugs also cluster together and are really easy to spot. At a quick glance, they look like there’s some cotton wool on your plant.

If you don’t get rid of them, the leaves of your plants will eventually turn yellow and drop off.

Treatment

You can easily dislodge the offending mealybugs by spraying them with water. In the shower is best. If there are only a few, you can gently scrape them off, wearing gloves of course.

Otherwise, you can use the same dish soap spray method that we discussed for controlling aphids.

For a chemical control, look for a product that contains natural fatty acids or a surfactant.

3. Red Spider Mites

Red spider mites are one of those houseplant pests that are quite difficult to control. They’re actually related to spiders and do, indeed, spin tiny webs all over your plants. However, they feed on the sap of the leaves. The tiny webs are there to protect an entire colony of spider mites.

You should be able to see the webbing on your plants if there are red spider mites present. However, the most prominent symptom of a red spider mite infestation is that the leaves will start to look mottled with tiny brown dots. This is actually a form of necrosis in the leaf.

Treatment

Because red spider mites hate water and humidity, placing your plants in the shower once a week will gradually reduce their numbers. Make sure you use tepid water. On the days between showering, mist your plant daily to increase the humidity around it.

If you have a very large infestation that you can’t get under control, it is possible to purchase predatory mites that feed on red spider mites. These predatory mites are known as Phytosieulus persimilis.

If you want a chemical treatment, choose a houseplant insecticide that contains a surfactant or natural fatty acids such as white oil.

4. Scale Insects

Scale is another insect that can be a little difficult to control. In fact, if you have scale on your plants, they may not look like insects at all. This is because these insects have an outer shell that is quite hard and adheres the insect to the plant’s leaves and stems.

Initially, these look like tiny brown nodules on the stems and leaves of your plants. Scale also produce a sticky, honeydew substance that will stick to your plant. This eventually turns black and looks just like a sooty mold.

Treatment

Scale insects can simply be rubbed off if there are only a few. But, because the young are mobile, you’ll have to be vigilant for a couple of weeks to ensure that you get them all.

Another thing you can do is dab a little alcohol onto each scale insect with a cotton swab. The alcohol will dissolve the insects. Alternatively, using the soapy spray that you use on aphids will soften the hard shell of the scale insects. Then you can simply wipe them off with a damp cloth.

If you’re after something a little stronger, try an insecticide containing permethrin or malathion. However, don’t use these chemicals on ferns because of their sensitivity.

5. Fungus Gnats

Fungus gnats are those tiny little fly-like insects that you often find on fruit that’s been sitting around for too long. They’re actually not harmful to your plants but they are a nuisance to have in the house.

You’ll find fungus gnats flying around your plants, but their larvae exist in the soil just under the top surface. They feed on organic matter and love moist soil.

Treatment

To encourage fungus gnats to leave your plants, make sure that you remove any dead foliage that’s ended up in the pot. You’ll also want to let the surface soil dry out. Consider watering your plants from the bottom instead until the gnats have disappeared.

You can also use yellow sticky paper that you can buy from your local garden center.

If you want to use a chemical control, try a spray containing Pyrethrin. You’ll have to do a follow up spray once the larvae emerge from the soil.

Final Thoughts

Houseplant pests are not as common as the ones that you might find on your plants outdoors. However, they do need to be controlled if you find them.

Most houseplant pests are sap-suckers and can easily be controlled with a spray containing dish detergent and water. You might need to apply this more than once but you should eventually rid your plants of these pests.
