Palms need to be kept moist. They should never be allowed to dry out or allowed to stand in water. Excessively wet soil can lead to root rot. Water thoroughly when the surface of the soil dries and discard the water in the saucer after the pot drains. Soil mixes for palms must be porous with plenty of organic matter to ensure both adequate moisture and excellent drainage.
Palms grow best with warmth.
Protect them from drafts near doors, windows and air conditioning. Most palms prefer temperatures of 60 F at night and between 70 and 80 F during the day. Many palms will benefit from cooler temperatures of 55 to 60 F during the winter, when not actively growing. Regularly rinse the foliage to clean the leaves and leach excess fertilizer salts from the soil. Wash the plant with a hard, fine spray of lukewarm water in your shower, or outside during warm weather, to keep insects such as scale, thrips and mites under control.
