If your sensitive plant’s leaves are discolored, this can be a sign it is getting over or underwatered. Be sure to let 50% of the soil volume dry out before you water. Then, thoroughly water the plant until the water drains into the saucer, emptying the saucer of any excess water. If the plant gets too dry, this can lead to browning leaves, while yellowing leaves can indicate an overwatering problem.
If your sensitive plant does not live in a humid enough environment then the leaf tips can turn brown or yellow. Try to increase the moisture in the air by adding a humidifier nearby or misting often. It’s also a good idea to give your plant a shower from time to time. If the plant is still struggling, be sure it isn’t in a drafty area.
If your sensitive plant ever gets a little too cold, this can weaken the foliage resulting in yellowing leaves. Avoid letting your plant’s environment drop below 55–60ºF. It will be very happy in a warm, bright spot in your home.
