How often should I water my palm plant?
Water when the top of the soil is dry. Browning of the tips can be caused by a number of factors: chlorine in the water, dry air, salt buildup in the soil from fertilizer, overwatering, letting it get too dry. I would suspect chlorine in the water first. Try letting the water sit for a few days so the chlorine dissipates or try using rain water. If it is very dry where the plant is located, move the plant to a location where it is more humid, or increase the humidity. Also, dry hot or cold air blowing on the plant could cause the problem.
