Freeze damage to foliage

[ QUOTE ]
That's why I asked. Do TGR's restrict growth or only cell elongation?

[/ QUOTE ]I don't think TGR's inhibit bud formation or development.

Sorry, my reply was meant to be rhetorical--I'm not sure.

I think Guy is right--TGR's do not inhibit bud formation or development. TGR's reduce cell elongation and direct some of the resources that the tree would normally use for growth into other processes. The result is smaller leaves and shorter internodes. At the last seminar that I attended on TGR's the speaker said that we do not yet really know all of the details of why, where, and how much.

The trees are going to have to use stored resources to put out more leaves, which means fewer resources for defense, which means they will be more susceptible to pests this summer. So maybe TGR's would be helpful.............
 
Here N/E of Atlanta plants are starting to suffer from drought. I've noticed some freeze damaged plants are recovering faster with watering.

Cool, thanks. Any more suggestions or thoughts?

Talked with our PHC guy today. He was against using TGR's for the freeze damaged trees at this time.

Agreed. We really need a slow, steady, all day rain.
 
Is the water helping to move the sugar/starch? Why an all day rain. What about an ?absorbic? acid. What reasons did your PHC guy give? Paitence, seeing lots of epicormic growth. Saw some Crepe myrtle and oak activity today.

Yes, plants need water to absorb and move nutrients and phyto compounds around. What Mark means by an all day rain is about 2 inches over a ten or twelve hour perion. Large amounts of rain over short periods of time just runs off of the soil and does not soak in.
 
I have been seeing a lot of the local "tree guys" cutting down hickories and white oaks because they look dead.

It is amazing how many people are convinced that their trees will not re-leaf out and that they have to remove them before they fall down.


I hope that Georgia starts to get some rainfall soon, both for the trees damaged by frost, and those awful forest fires.

I certainly wouldn't cut anything yet because of the freeze. But, I am concerned that the freeze may push some of the larger, older trees (particularly oaks, tulips, and some hickories) into the beginning of a mortality spiral.

I hope you guys got the rain we did- as prescribed. Epicormic buds are busting out and I am also seeing new twig extension!

We did get some rain Friday night. There is new growth on many of the trees that were damaged by the cold, but it is too early to tell how they will fare. Figs and Jap maples seem to be pulling through, but we'll have to wait and see about the oaks and tulips.


In some areas the canopy cover seems like early fall--the leaves are sparse and the shade is thin and broken.
 
Hickories exploded with the sun yesterday! Saw a large Post Oak (meeting the Stihl unfortunately) pushing out new twigs from the terminal. Poplars under 10" dbh doing fine, larger are struggling. I have looked at some larger trees with cambium damage from freezing. Mahk, any answer from your PHC guy about not using TRGs?
