Pecan Trees
Q. Not sure if you know the answer to
this one or not but thought I would try!
My Mom has a pecan tree (don't know how
old) and it bears every year. She was looking
at it and it seems to her it may have died.
Some of the limbs look dead and some of
the leaves are black. (I know doesn't sound
good huh?) Is it normal for pecan trees
to do that before they leaf out for the
spring? We live in Louisiana and our weather
is always nuts! (No pun intended!) We just
have never noticed it doing that before.
I know you can't really tell for sure if
you can't see it but thought you might have
some suggestions. Thank you.
A. Yes the Internet is a bit hard to use in answering exact questions
at least now before they make it 3-D!!! But
I suspect the worst. It is definitely not normal. I want you to take a couple of the bad branches and bend them. Check to see if they snap. If they give under pressure that is a sign that there may still be life left. If they snap
and the interior is bone dry that stem is dead
and you would need to continue sampling the rest of the tree. If one bends go ahead and cut it off
about one foot in length. Look at several cross-sections and see if there is any green or moisture. If the color is black or brown I suspect that the tree has: Suffered a fungal attack
Died of old age or weakened state
Been damaged by cold and wind during the winter. Do me a favor and write me again after you have gotten the results. That will give me more info to research for you!
Q. My mother-in-law lives in Virginia and
as we were just struck by hurricane Isabel
her pecan tree in the front yard had some
branches crack and blow off. I was wondering
since the whole tree has not been uprooted
if we cut back only the damaged limbs would
they grow back? The tree had been in excellent
condition prior to the hurricane and the branches
that are still on the tree appear to be thriving. I
appreciate any advice you may have regarding
the tree. It has sentimental value to
my mother in law as her late husband planted
it when they first moved into their house.
A. Certainly go ahead and prune off any cut or badly damaged branches. Apply
a sealant available at your local nursery
to prevent water loss and possible infection
from an airborne fungus. If a branch is
merely weakened and still attached to the
main trunk construct a crutch and secure
tightly to the branch and then to the trunk.
Use rubber around where the wires touch
the tree so as not to cut into the bark.
Remove only after well-healed. Give regular
feedings to keep up the tree's overall health
and strength. Best of luck in saving such
a fine memento.
