Common problems
If overwatered, the roots may rot and leaves can turn yellow. Too little water causes fronds to dry and brown. Low humidity may cause leaf tips to brown. Pests are uncommon but watch for scale or mites.

Notes
Prune old or damaged fronds to keep the plant healthy and attractive. Repot every 2-3 years to refresh soil and allow room for growth. Sensitive to cold drafts and dry air; keep away from heaters and air conditioners.
