Many people enjoy having plants inside their homes, especially when it is cold outside. But sometimes houseplants need a little help. If they are struggling, houseplants will let you know. They show discolored leaves, and their stems droop, or no longer stand strong or tall. And there will be little or no growth. “Plants send signals simply by the way they look,” said Dawn Pettinelli, an Extension educator at the University of Connecticut. “If they aren’t getting enough light, the leaves will yellow or turn brown and they will be slow to develop.” Leaves with the wrong colors can also mean other problems. These include root problems, insects hurting the plant, the wrong soil moisture, or bad light conditions or temperatures.
