WHAT is wrong with our Concord Grapes this year ?

Gardiner, ME(Zone 5a)

Hi everyone,
When we moved late in 2006 we still had Grapes on these vines,I let someone else pick them.
In 2007 I had more Grapes than I could use but they were picked and last year 2008 I picked alot but also alot were still left on the vine.

Now in 2009 we have almost no new shoots as you can see.
Can these be saved and how ? I sure hope so !

Any advice/information will be greatly appreciated.Thank you.

Maybe it's because of the freeze this past winter. My forsythia did the same thing and half my rhodies are not blooming either.

Hi Quilter5bdsr,
it sure could be ,we did have a brutal winter just like you.

But I thought maybe because I didn't have time to snip a little here and there...called pruning :-)

It could be that too. I'm not the one to ask about them. I know very little besides the fact that I LOVE homemade grape jelly!!!
Are you still working on your miniatures?

Gardiner, ME(Zone 5a)

OH YES ...I HAVE my Grocery Store ALL DONE,the CHRISTMAS bakery is well on it's way and a quiltshop about 1/3 done...gosh it it sooooo much fun to make the bolts .

Riding around a lot of rodies got the cold blast. Mine is sad sad looking.

I don't have any of those but a 6- 7 ft large climing rosebush which was covered with roses last year had to be cut to the ground.That one is close to the grapes so it probably was the winterdamage.
But I am wondering if it ever will recoop ?

Would it be called - Winter Kill ? serious

Gardiner, ME(Zone 5a)

You're definately right ,here it is called winterkill.

But since I have a live rosebush even though I had to prune it down to the base I called it winterdamage instead of winterkill .

If you cant get an answer here, you might want to try the Vines and Climbers thread.

I was going to do that in the beginning but figured maybe someone else here in the east had the same problem.Thanks I will do that.

Can you show us some pictures of your new rooms? I'm a quilter and would love to see that one!!!

Fortunately, my red seedless is doing fine. It's young at about 8 years old but I prune severely every March. The poor thing looks scalped when I'm done but each year it gives me more and larger fruit.
I have one problem, the grape plume moth larva. An adult lays one egg in each new spring shoot. The larva eats the newest growth, often the grape 'flowers'. I have not found a pesticide to deal with it so I carefully examine every shoot for curling indicating the larva. Hand picking works fine if done often in May. The vine is small after pruning so it's not as daunting as it sounds. I don't know what I'll do when it's 30 years old but I'll likely not be around anyway, lol.
Your vine may be old and in need of a hard pruning. Is it getting shaded out?
This is the nasty grape plume moth larva, about 3/8 inch long.

Stupid Andy didn't look at your pic, lol.
Get the pruners out and get rid of all the deadwood some time this summer. You'll know what is dead by then.
Next March, prune the live shoots to leave only 3 or 4 (no more) leaf nodes (where new shoots sprout).
Your vine will appreciate it and reward you next year.

I don't know anything about grapes but I only have one bloom on my 3 rhododendrons this year from the last nasty cold winter.

Hi quilter5bdsr,
Yes I sure will take some updated pictures of the rooms but I have been out of town,back home and tomorrow gone again for a whole day.But I definately will do it...I promise.

Andy,thanks for mentioning the hardpruning.I went to the biggest nursery around here and talked to somebody about my grapes.Besides it beeing a hard winter it needs pruning.( even though I never hardly pruned mine at the farm and we had grapes every year)

But he suggested to prune them lightly right now,feed them 5-10-10 fertilizer andthen hardprune in April.So i will give it a shot.

Meredith I had the same problem - only four blossoms on mine. It is covered with new growth so hopefully next year will be spectacular if winter isn't too bad this year.

Southeastern, NH(Zone 5b)

Yes lets hope! : ) I can't complain after seeing others around town that lost half their top growth. Most people had to just cut them back.

Brockton, MA(Zone 6a)

I grew up in NH next to a dedicated gardener. He grew everything, lol. I watched him prune his grapes one spring and asked why he cut so much off. His reply "I'm growing grapes not wood."
That was over 50 years ago, he was my gardening mentor who's teachings benefit me to this day.
