Tropical palm plants are a popular choice for indoor planters. They require slightly more care and attention than other houseplants, but are still relatively easy to grow. However, palm plants can be finicky about their growing environment, and imbalances can cause brown spots to appear on the leaves. But if you restore the balance, your plant leaves will become become lush and green again.
When a palm plant does not receive adequate water, the leaves will turn brown. Proper watering will remedy this problem.
Palm plants require very small amounts of fertilizer, so they should be fed lightly. Too much fertilizer can cause the tips of the leaves to brown.
Lack of Humidity
Tropical palm plants require a relatively high level of humidity in the air. Misting the leaves will add needed humidity.
Cold Air Exposure
Drafty locations will have a negative effect on your palm plant. Tropical palms can adapt to cooler temperatures, but they cannot tolerate exposure to cold air.
Palm plants infected with leaf spot disease will display brown spots on leaves. Affected leaves should be cut off and discarded. Leaf spot disease is caused by over-watering or chilling.
