Q.peace lily indoor plant
My peace lily leaves turn black. Can you possibly tell me why and what I should do about it? Thank you so much.
Black leaves can be the plant suffering from a build up of soluable salts. This can happen when the water is not allowed to drain though the pot.
Salt builds up and burns the roots.
Water the plant by placing in the tub or sink and run water through the soil well. Allow to drain and then dry out. When the top inch or so is dry, repeat the process.
If the plant continues to turn black it may be to far gone to save.
