|We have some Phoenix Roebelenii's that are turning yellow with brown tips at the end of the leaves. Are they getting to much water or not enough? We have been watering them a couple times a week, giving them approx. 1 1/2 gal. each watering.
Also, when is the best time of the day to water? Early morning or late in the evening for the trees and lawn?
Thanks for any help you may give me.
|If the lower fronds are yellowing it may be normal and natural; if all the fronds are yellowing, over watering or a need for fertilier or an iron supplement may be the cause. Morning is the best time to water and how much to apply or how often to apply really depends upon your soil type, its ability to hold moisture, and the weather. You'll want to apply enough water at one time to percolate down and wet the entire root system. Twice a week is usually adequate in the summertime. About the only way to know how deep the water is traveling is to probe the soil with a metal rod or wooden stake. Moist soil is easy to probe; dry soil will provide resistance. The goal is to wet the soil 18-24 inches below the soil surface directly beneath your palm. Hope this information is helpful.|
