Mary:

A fence 16 ft long could be used for either one or two grapevines. There is no problem associated with either situation. If you have room elsewhere, then just plant one there. If not, two will work.

When I was in Amarillo I tried many varieties of seedless table grapes. My favorites were Canadice and Reliance. Jupiter is also highly recommended by many and is worth a try in Z5.

The Fruitnut

I'm growing (trying) Reliance. Rabbit just pruned it for me (fencing got moved), so it will be awhile before i get fruit.

Jupiter by a country mile. Seedless, vigorous, very productive, large berries, and delicious. Then Glenora. Seedless, vigorous, average productivity, smaller berries, but the most delicious to most peoples' taste, and with beautiful red foliage in the fall. Both available from starkbros.com, among others.

I liked Glenora when in Amarillo. But it was not hardy there in Z6. It is toted as very hardy, but wasn't for me. Try at your own risk.

The Fruitnut

Thanks Everyone,
I had read some about the Reliance. I was thinking that
one have very small fruit? NOt sure where I read that.

I will do some research on the Glenora. Is that a warmer
[z 6-7] grape? I would like to have some table grapes and
or someday even try some wine grapes.

I was hoping my 16 ft fence would hold up 2 grapes, as
I was hoping to try more than one variety.

You all have been very helpful!
