A plant may be healthy when you bring it home from the nursery but it dies after a few weeks in your care. If it was given the correct amount of water, the culprit could be the lack of enough sunlight. With very little sunlight, the leaves often turn pale, wilt or the plant will not grow – which means no food energy is produced. On the other hand, if the plant has too much sunlight, its leaves will get burned. If too much sunlight comes through your window, move the plant back from the window or put a see through curtain on the window because plants lean toward the direction where light is coming from (photo kinesis). To have healthy houseplants, give their pots a quarter turn every time you water them.
