When to Water Pecan Trees
The critical periods occur when weeks pass without a rain. However, the tree and crop have the greatest water needs in
(1) March, immediately before growth begins,
(2) June, as nuts begin to size,
(3) Late July, as kernels begin to fill and
(4) Early September, as kernels continue to develop.
Severe droughts during these four periods can result in complete crop failure or serious crop loss. A drought during the last period can also result in a poor crop the following year.
