Why do leaves on houseplants turn yellow and brown?


assistant
Often houseplant leaves turn yellow and brown for a few common reasons. First is overwatering. Houseplants are kept in containers that can retain water which can lead to root rot if not watered carefully. Some houseplants prefer the soil to dry out between waterings and many home gardeners end up watering before the soil has dried up sufficiently. Too much water in a container can lead to root rot which first can show symptoms in browning, dropping, and yellowing of leaves. Another reason for leaf discoloration is under watering as some plants prefer the soil to have a level of moisture at all times. Other reasons include too little sunlight which limits the plants ability to photosynthesize. Also, even too much sunlight can cause burned leaves.
