A Homeowners Guide To Pecan Tree Care
When one stumbles across a website such as this, an entire database devoted to the art of growing pecan trees, he/she might draw the conclusion that growing a pecan tree must indeed be one of the most difficult and complicated chores on earth. I assure you it is not true. Pecan trees have survived and thrived throughout Texas and the southern United States for...well, who knows. Pecans were a mainstay diet for our Native American Indians (I hope I'm politically correct there.)
It is important to note that pecan trees thrived for centuries without special attention only when conditions were right for their survival. The same will hold true with a pecan tree that you plant on your property, or one that you perhaps inherent with the purchase of your property. They aren't the type of tree that you can just ignore like you can that Mulberry tree in your back yard, that, as you are sitting here reading this, is taking matters into its own hands and firmly planting its massive root system into your sewer pipe.

There are some problems you may encounter. Insects (bugs) can cause considerable damage if not controlled properly. Part of our pecan orchard management program is to NOT just go around haphazardly spraying pesticides 'just because.' There are entire seasons that we do not spray our trees. This should be your policy, also. Spray only when needed, using the least amount necessary to get the job done. If you have a newly planted tree, it is very important to control aphids and other bugs that may 'eat your leaves'...no leaves, no tree.
You can treat most of your insect problems with the usual 'over-the-counter' sprays found at your local home and garden center. The most common problem associated with pecan pests is that sticky 'syrup' that just floats through the air and coats your car windshield and everything else. This is caused by aphids, or as the nut gurus have discovered, is a result of Aphids uh...pooping on the leaves of your tree and tiny Micro-organisms feeding on uh...IT, which since IT is on the leaves, result in leaf damage and the resulting 'floating syrup.' To clear up his problem, simply spray your tree (or your neighbors) with an over-the-counter spray that claims to control Aphids.
Your pecan tree need Zinc and I personally think that it is almost as important as water for your tree. Signs of zinc deficiency are pale green leaves, bare branches with a cluster of small pale leaves at its tip, and dead branches in the tops of your trees. A lack of zinc also prevents nuts from filling out. Zinc is available at most garden centers, either in a liquid or powder form. You should spray the foliage on your trees with a zinc spray three to four times early in the growing season, beginning with leaf bud in spring and regularly every three weeks or so into mid-June. Do not spray zinc during the heat of the day, as it could cause leaf burn.
Fertilizing your pecan tree is necessary to ensure growth and nut production. Ammonium Sulfate is a common nitrogen fertilizer for pecan trees and is readily available at home and garden centers. While the 'nut gurus' have a whole book of formulas and theories concerning pecan tree fertilization, it is usually accepted that for each inch in diameter of tree trunk (a foot above the soil) you should apply one pound of fertilizer. If you don't want to rummage around the sewing box for your wife's measuring tape, you can also apply one pound of fertilizer for each year of your trees age. You should apply fertilizer twice during the growing season, once at mid-March and again in mid-May. So, if you determine you need to apply ten pounds of fertilizer (because your tree is ten inches in diameter or ten years old) you would make two applications of five pounds each. Apply evenly underneath the entire canopy of the tree. I recommend that you water your tree deeply prior to application, then water only lightly to dissolve the fertilizer just beneath the soil. This allows the feeder roots access to the nitrogen over a longer period of time.
