sap on tips of peach tree branches

 

   I bought a Hale Haven peach tree at Lowe's about 9 weeks ago, and
planted it with half a bag of composted cow manure under the roots.  I
also mixed in some of that dehydrated plastic to help it get through any
dry spells.

   The plant grew rapidly, and now has put on 10-12" of growth on all
the branches.  I was surprised about 3 weeks ago when the tallest branch
suddenly flopped over.  There was a small wound of some sort, and the
top ~18" or so of the tree was gone. (it is about 4' tall total, and
maybe 1/2" at the base.

   I noticed that the fast growing tips of maybe half the branches got
shriveled  and crisp about a week or so ago, but only a half inch or
less of the tip of each branch.  I thought maybe it was during the 3
days or so we were gone, and I wasn't able to water the plants.  The
rest of the tree looked a healthy green.

   Now I notice that the tree appears to be putting on new growth out
around the former tips of each branch, with 1-2 new growths appearing.
Some are already nearly half an inch in length.

   However, the big problem that I see is that maybe 40% of the tips of
the branches - most of them with the tip damage - are oozing a clear,
gelatinous mass that stays right in the area.  I'm not sure if this is
just because the tree is very rapidly growing, with a lot of turgor
pressure right now, or a sign of a more serious problem.

   The tree had a couple of spots on the trunk where it looked like it
sustained damage in shipping.  Normally I wouldn't consider such a tree,
but I had already tried 4 different nurseries, plus 3 or 4 of the other
stores in the area that have fruit trees in the Spring.  Home Depot was
the only one with a Hale Haven peach, which was the variety I wanted.
These spots have completely healed over now, due to the rapid growth of
the plant.

   There are always a number of small ants on the tree, and I've noticed
some small round areas appearing at the base of each leaf.  It almost
looks like the ants are getting some sort of fluid there, but I'm not
sure if it is actually harmful.  I'm keeping my eye out for aphids, and
if they appear, I'm going to spray regularly.

   Anyone have ideas for what might be causing this issue?  Tree appears
to be growing very rapidly, and looks like it would be on track to go
from about 4' tall to 6' or 7' this year, except that the sudden tip
dieback and 'gelatin' on some of the branch tips worries me.  I'm
wondering if this might be infested with something.  If so, perhaps I
need to cut my losses now, take it back, and get a new tree?  I'm hoping
not, but still wondering.

                                                     Thanks!

Lesser Peachtree Borers?

Sounds like tip borers, they can carry a fungus that can kill your tree.

 



Do a google using the terms 'peach' and 'gummosis' and look at the pics that
come up to see if this is the porblem.


More likely the ants will be farming scale insects of some sort. Ants move
the scale insects around and spread them as they eat the exudate from scale
insects.  There are a bout a squillion differnt forms of scale but most can
be treated.  id try to confirm if it was scale then to treat it and do it
repeatedly and the ants just might move elsewhere.

 

   Here are some extreme close-up photos I took of the problem this morning:

   In the second one, you can also see the couple of places on the
right, near the base of the peach leaf, where I think the ants are doing
something to the tree - almost like they're getting sap.  I don't think
this is a major issue like the tip dieback and clear gelatinous mass,
though.
