Question: 612-3711
Why have the pecan trees survived the drought here in Texas? Do they have a long tap root? Jack, Austin

Mort's Answer:
Indeed, they do. When they are four or five years old they start to send out long lateral roots, as well. Usually trees that are drenched with water are vulnerable to the wind knocking them over. Trees that have a dense screen like evergreens will be good candidates for being toppled. Deciduous trees with smaller leaves allow the wind to pass through the branches and have a good chance to survive. Soft wood trees like willow will break or snap in wind storms. Live oaks with their smaller leaves are sturdy as well. Fallen trees can sometimes be resurrected with heavy equipment by digging out the soil on the lee side and cutting clean the ripped roots. Smaller trees and shrubs can be relieved by hand dug trenches. These holes should be filled with good soil and no fertilizer.

We have a 25 foot pecan tree that produces a lot of nuts. When they fall to the ground, they are being eaten by some critter. They are hollowed out. What could it be? Dave, Taylorville, IL

Mort's Answer:
It could be a ground worm. It is most likely nut case worm that has been growing in the pecan. You need to spray with an oil spray each fall and spring. You also need to spray with Bordeaux Mix at least seven times in the spring and summer. Do not use any spray, when the flowers are on the tree. If you cannot get Bordeaux, spray with a Home Orchard Mix. Follow directions on the packages. You can also put vaseline on the trunk at the bottom every year.

My five foot pecan that I planted last fall is without leaves. I cut a branch and it is still green. There are no signs of insects on the plant or root. George, Boaz, AL

Mort's Answer:
Our mild winter has caused a few problems. Budding can be delayed this year. Some varieties are grown as root stock for grafts and do not bud out well. Because they thrive in lots of heat, you will need to be patient. I would cut six or eight inches off each branch to stimulate growth. Use a high nitrogen liquid fertilizer on the roots. A bucket of manure tea should suffice.
