I just planted two grape plants – a seedless Concord and a seedless Lakemont. They are leafing out well – very exciting! I’ve read a bewildering array of info on how I should trellis them. They’re in an area of my garden where I hope to have a pergola or other lovely structure for them to grow on someday, but in the meantime I need to construct some kind of support for them. How much support will they need this first year? Do I need the post and heavy guage wire system, or can I just support them with a stake this first growing year?May 27, 2010 at 1:47 am #29471
I supported my grape with a bamboo stake for its first year, which was not really adequate, but I think a wooden stake would have worked well. The Cornell grape fact sheet has a good description of what to do the first year.June 3, 2010 at 11:37 pm #29486
Thank you, Leslie. This fact sheet is very helpful. My grape plants are really taking off so I’m thinking a single stake won’t work for me, either. I’d better get going on my trellis/fence!June 7, 2010 at 3:22 pm #29493
We live in Los Angeles and 2 years ago planted four grape plants: 2 Flame seedless and 2 Thompson green grapes all in the same area and conditions. However, only the 2 Flame grape plants have produced any fruit. All of the grape plants leaf up very profusely, everything looks good, but then only the red ones get any fruit. Any ideas on how to get the green grapes to fruit?
A co-worker of mine has experienced the same problem with her grape plants and suggested we graft some of the fruiting ones to the non-fruiting ones (in desperation). I’d love to hear from anyone who has a suggestion!June 8, 2010 at 1:24 am #29494
Do you prune the vines? Pruning grape vines makes a huge difference for grape production. Without pruning the canes don’t receive enough light to stimulate fruit production; they shade themselves out. Some grape varieties are better cane pruned, and some are better spur pruned. Thompson seedless is on of the grapes that does better with cane pruning. The California cooperative extension has a lot of information on both ways to prune grapes.
