I am not the grape expert by any means, so I'm taking a rough stab, in the hopes that someone with a lot more grape knowledge than I have will correct my mistakes, but ...

1) Most grapes are on their own roots. Some, mostly Vitis vinifera and its hybrids (European wine grapes) are grated on rootstocks that are resistant to specific problems.

2) In Mass, I'd personally suggest trying either the old standards, Concord, Niagra, Delaware, or some of the newer American grapes. California type table grapes won't grow in colder climates, alas.

3) Seedless grapes are like seedless watermelons -- you find the random seed once in a while due, but not very often. Most of the seeds are tiny, soft, and undeveloped.

Thanks :) any advice is wonderful :D
yes, i've heards some good things about those two...i'll see if my local nursery has them..

Grapes on their own roots can be susceptible to bugs and disease, so when nurseries sell a vine it is always grafted. They don't want to sell you something that may live for 3 or 4 years then die.

I'm placing a link for you here. This is the National Grape Registry. When you click on a varietal, you will see if it is a wine or raisin/eating grape, and you will find out what climate it thrives in. There will be a list of nurseries that carry it.

Vanessa Grape is seedless and originated in Canada, so it will probably do fine where you are. I have heard it is sweet and wonderful.

Maybe it depends on your location, but I know for a fact that when nurseries sell a vine it is not always grafted (at least not around here). Even vinifera grapes are grown on their own roots by the local commercial vineyards. We don't have phylloxera here, cold winters are much more of a threat. Own rooted vinifera vines are more desirable here because they will grow back if killed to the ground by a deep freeze.

I think the answer to your rootstock question is that it probably varies by location and variety. The only way to be sure is to ask.

Jupiter, Reliance, Glenora and Himrod were recommended to me as great grapes on this forum when I asked a similar question here some time ago. I do not have much heat in my yard (microclimate) and hence these were recommended to me. Of these, I got Reliance and Glenora to try this year. Good luck.

It /did/ look like it was ownroot..but i wasn't certain..only time will tell i suppose XD as long as it's ahppy and healty,,im happpy :)
Planted it today and gave it a long drink..also got a regualr concord and planted her as well :) I'll kepp you updated!

European grapes are often grafted onto American rootstocks to give them disease resistance, but 'Concord' is American, so its own roots are fine.

I haven't tried 'Seedless Concord' but I like 'Concord.' It has a strong labrusca flavor, sometimes called foxiness. Many people don't like that flavor, though. Another interesting flavor is muscat, a sort of floral perfume. 'Jupiter is a grape with muscat flavor, so you could try that for diversity in flavor.

I planted my first grapes last year, so I'm no expert, but I hear that it's very important to prune them properly. Otherwise you get huge vines with hardly any fruit. You'll want to look up how to prune them.
