Should you wipe pothos leaves?
Pothos plants will benefit from a regular dusting. Their broad leaves quickly collect dust. The dust can look unsightly and interfere with photosynthesis. To keep the plant looking its best, wipe down the leaves with a damp cloth.
Can plants recover from black spot?
No. Once a leaf is infected and damaged by leaf spot diseases, it will not recover or turn green again. The diseases kill the parts of the leaf they grow on. For deciduous trees this is not usually a problem, as these trees put out new leaves each spring.
