a hackberry defoliation
« on: July 31, 2012, 06:57 PM »
I rescued this netleaf hackberry about 4 years ago. It never grew much and this spring, I almost traded it off. I always let the branches grow to 8 or 10 leaves, then cut it back to 4 or 5 leaves, and it never responded well. Two weeks ago, I noticed all the leaves had brown edges from the summer heat, and thinking the photosynthesis factory was about shut down, I defoliated it. These photos were taken 14 days later, and the whole point here is that every place a leaf was growing, now a new branchlet is growing with anywhere from 5 to 7 new leaves. I increased the leaf count  5 to 7 times in just two weeks. More important, knowing that new sprouts on cedar elm are branchlets also, and not just a new leaf, I defoliated one of my cedar elm that already showed signs of new growth. Should have the new verdict in two weeks. On this hackberry, I increased the ramification more in two weeks than it did in a few years. Comments or similar experiences welcome. Don't regard the tree position or pot, as I said, I was about to trade it off. Larry

Nice work, Larry.  You would think that if the tree has never ramified by normal trimming of the shoots in spring, there might be some weakness and it wouldn't respond well to summer defoliation.

Keep us posted on the cedar elm.  It should respond well.  I just did a water-elm a few weeks ago, in preparation for fall showing.

Thanks Zach. Will post an update in two weeks.  Is your water elm from Catahoula? Larry

I'll be interested to see the update, also I wonder if it would cause more winter twig-dieback than normal. Not that you'd have that in Texas, I'm just thinking about my hackberry here.  I've never defoliated it... And for me, it might be too late in the season, but some of my leaves are giving up in the heat, so I've thought about it.  What do you think???

Yes I'd think it's to  late to defoliate in Ohio. Here, I.m not expecting a frost till November, and if one or two come sooner, I'll put them in the greenhouse overnight. My deciduous bonsai don't get much color in the fall. I'm thinking the leaves fall off due more to short days than cold weather.  The cedar elm is coming back nicely, it's been 12 days, and when it's full, I post a pic. Larry

Thanks Larry, I'll give it a shot next year!  Mine is pushing new leaves out now where the damaged ones are falling, so it's sorta self defoliating... But I'll bet it does not put out new branchlets, that's very cool.
