yellow leaves on my house plants
Yellowing leaves on houseplants can be caused by various problems. Either over- or underwatering can lead to leaf yellowing. Overwatering kills roots because they don't get enough oxygen. With damaged roots, the plant doesn't get enough water internally, even though the soil is wet. Anything else that damages the roots will also lead to leaf yellowing. So if a disease attacks the roots, leaf yellowing will show up. Some insects cause leaf yellowing as they feed on the leaves. Look closely at the leaf undersides for evidence of insect feeding. And some leaf yellowing is natural. As leaves age, they eventually die and fall off.
