What do you call these things hanging from my grapevine? Can I cut them off now or do I have to wait until the vine is dormant?
I believe they are called AIR ROOTS. They really aren't needed for the plant to grow and produce grapes. They are more for anchoring to whatever they are trying to climb and grow on. They can be quite ugly, so just cut them off.
It appears these are called 'Aerial Roots' and although weird looking can be removed without damaging your grape vines.
"Aerial rooting in grapes has been described as an indication of cold injury."
Here is a link that explains what may be causing your problem.

Yes, these are aerial roots.
I found an interesting post by Eric Stafne (Mississippi State University) about aerial root formation in grapevines. grapes.extension.org/
I have grown a grapevine now for 4 years in my greenhouse. The root is outside the greenhouse, the vine is inside the greenhouse. All I get is bunches of small pea size grapes, very sweet but a lot of pips. Have taken advice over the years; pruning, thinning, feeding, watering, training, etc.
But it is the same. I'm about giving up on it now. Gave it my all. What can be the problem with this vine, is it just a runt? Help!It's frustrating to try garden tips to no avail! You didn't mention soil, so I'll add here that too much nitrogen could be a culprit. However, assuming your grapes are Thompson, I'll venture that expectations are possibly not realistic.
Make sure you are pruning the vine after the growing season is over. Letting the vine grow wild can be the cause of small grapes.
You do not grow the same type of grapevine and you do not grow a grapevine the same way if you want to have, big beautiful grapes to eat, grapes to make good wine, or if you want the grapevine to grow over an arbor. But in any case you should not grow a gravevine inside a greenhouse. The grapevines that produce wine are not good to eat. On a wine grapevine for the winter season we cut off all the branches and in the spring, out of the new branches starting from the floral buttons we leave only one branch or two branches at the most to grow along a wire and that's all. The grapevine that produces good quality wine is not left to climb it is maintained horizontal, it must receive all the nutrients and the whole field must receive as much sun as possible, that's why the plants are facing south in a slope to have no shadow. By law the grapes are picked up at a given time not earlier not later and for the grapes to receive as much sunlignt and warmth as possible we take off the leaves. In France it is forbiden to water the wine grapevines. It means that to make good wine you grow only a few grapes on the same plant, you do not water it to concentrate sugar as much as possible and you give it as much sun as possible.
For the past several years we didn't get to enjoy our Scuppernong grapes, except the ones we found as they were beginning to get ripe. Starting in August, before the grapes were fully ripe, the raccoons came at night and had a family reunion in our grapevine. They didn't even clean up after themselves.
Even if you don't have a garden space, you can successfully grow grapes in a container on your patio or deck. This is a page about growing grapes in containers.
This is a page about propagating grape vines from cuttings. Grape vines are a good candidate for propagating from either dormant or green cuttings.
I have a large garden and would love to grow a grapevine. How do I start?
By Charlie
First, check with your local nursery to make sure you are in an area where grapes will grow. They will also advise you which varieties are best. When I was a child in Illinois we had a concord grape vine in our back yard which did produce grapes.
Now I have one in my yard in Santa Clara county in California which is also doing very well.
Next, plant it somewhere that you can have a very good trellis. Mine is made from 2x2s and leans against the side of the house. It supports the almost 100 lbs of grapes every year without falling down. That is just from one plant!
You could also train the vines horizontally along a fence. Every Fall we prune the vines way back to just the thickest ones. It might be a good idea to go to the library and take out some books about growing grapes or buy one at that local nursery.
How do I transplant 4 year old Merlot plants?

We had a very hot, dry summer. I covered my grapes with netting to keep birds out, but as my grapes were ripening, something proceeded to eat them, leaving the stems on the vine and the grape skins on the ground. What is eating them and what can be done to prevent this, as the netting doesn't seem to be doing the trick?
