Troubleshooting a Succulent With Yellow or Brown Leaves
The most common way people notice that their succulents have some kind of problem is that the leaves start to change. Finding yellow or brown leaves on your succulent may or may not be cause for alarm, but it is definitely something to take notice of and address right away.
Too Much Light
Too much sunlight can cause normally dark-colored succulents to get a bleached, yellow appearance. Sunburn or sun damage will cause brown spots, especially on the top of the plant where the light is most intense. Younger plants are more vulnerable to light damage than mature plants. Succulents should get lots of bright sunlight, but most varieties can’t handle direct sun for very long. Move the plant to a location out of direct sun.
Overwatering
Too much water causes your plant stress and results in yellowing leaves. Overwatering appears in the lower leaves first. They usually feel soft and mushy. Over time, the yellow leaves turn brown or black, then fall off the plant. Reduce watering and allow the soil to dry out thoroughly between waterings to prevent this.
Underwatering
A severely dry succulent will have brown, shriveled, dry-looking leaves. This is less likely than other reasons for leaf discoloration, since succulents can generally survive long periods without water. However, if you forget your succulent for weeks and weeks, you’re likely to find some brown leaves.
Natural Leaf Drop
As succulents grow, it is normal for their lower leaves to dry up and fall off. If you see yellow or brown leaves at the base of the plant and it seems to be healthy otherwise, this is probably just part of its regular growth cycle.
Removing Yellow or Brown Leaves
If you see yellow or brown leaves on your succulent, it is usually best to go ahead and remove them. A leaf that has changed color will not generally be able to recover and go back to its previous color and health. Once you remove the unhealthy leaves, the plant will be able to devote its available energy to recovering and creating new growth.
