Too much fertilizer can cause a plant’s leaves to turn black. Blackness of leaves often results from an overdose of salts in the soil. A combination of fertilizer and soil that does not drain well can create salt buildup in the soil, which can cause leaf discoloration.
Similarly, should I cut off black leaves?
Should you cut off dying leaves? Yes. Remove brown and dying leaves from your house plants as soon as possible, but only if they’re more than 50 percent damaged. Cutting off these leaves allows the remaining healthy foliage to receive more nutrients and improves the plant’s appearance.
Correspondingly, what to do when plant leaves turn black? Black leaves on your plants can be reversed, but in some cases are a sign of disease, fungus, or bacterial problems. Because of this risk, the safest thing to do is to remove the plant from your other plants as soon as you notice. This action can prevent a tragedy in your collection.
