Palms, like many houseplants, benefit immensely from spending the summer outside . When they are moved outside for the summer, gradually accustom them to higher light levels. Indoor palms should not be placed in direct sun while outside. Fertilize either with a dilute liquid fertilizer or use a slow-release fertilizer in the container. Fertilize only while the plant is actively growing.
Excess fertilizer can be harmful to palms.
Palms do best when their roots are confined and may only need re-potting every two to three years, if roots fill the pot. Repot when needed in spring or early summer. Most palms are propagated from seed. Some can be divided to create new plants. Do not use any of the leaf shining products on palms as they can severely injure the foliage.
