Grapevine flowers

Both of my grape Vines have flowers that have burst now, do they get pruned off or are the grapes coming behind them? Do I prune off some of them to make the grapes bigger on the other stems? This is the second year, and I have more this year than last.

Cuttings identification

Hello, We have some cuttings from a local backyard vineyard. We have perhaps Pinot Noir, Cabernet Savignon and Merlot. They are ready to go into the ground. Note, these are just some cuttings no root stock. We thought we would just see if they grew and they did. Vines are in one gallon black pots and are about 12"tall. NOW we want to identify them because we are planting about 15 plants along with a few native vitis californica. We are in Saratoga, CA. This is for landscape and enjoyment. Since the leaves are not mature, we are having some difficulty doing identification. Some plants are taller and more upright with leaves coming out on opposite sides of the stem. Others are shorter and shoots are bunched from one bud. What else will help us identify them? Will leaf veining help identify? OR the under side of the leaves? Again, shape of leaf is helping but not definitive because we are not expert. Thank you. Cindy

Assistance requested to identfy damage or disease on grapes.

These symptoms started on some grapes near the end of last week and the condition is spreading fast. There was a Pylon application four weeks ago to manage spider mites and nothing since, so I don't think it's related to the spray. Plus, other types of plant material were treated with Pylon the same night with no subsequent damage.

The condition is only in the middle of the plants. So far the upper juvenile leaves and lowest leaves are not affected. Any ideas would be helpful.

Thank you,

How far apart should rafters be spaced on pergola if used for training grapevines?

I plan on building a metal pergola to train a total of 2 grape vines. However, i need advise on how far apart the rafters should be spaced and if weather the vines should run perpendicular to the rafters or in line. Plus, do i need slats on top of the rafters? If yes, then how far apart should they be spaced? Also should the rafters run along the longer side of the pergola or the shorter side? The pergola would be 18 ft long by 13 ft wide and 8 ft in height.

Grape canes too long

My grapes are 20 years old. I pruned them minimally and they are overgrown and almost wild. Is it too late to shape and prune them?

neglected grapevine

I have a small unpruned grapevine in my suburban garden in Ireland. I am about to prune it now but all of last year's canes start from a point some distance away from the main trunk _ they sprout from older wood,not from the trunk. Should I remove most of this older wood and in doing so lose last year's growth and just leave one one or two of last year's canes (which come out of old arms a bit away from the trunk? I would like to cane prune and not use the cordon method as I do not have room at each side for long cordons to develop.
Thank you.

grapes dropping off before ready

I believe my vine is a concord grape. Was here when bought house 50 yrs ago. Noticed 3 yrs ago all were gone in August so I have covered it the last 2 yrs so birds could not get at them. Looked like a good crop this year and I had to pick them today because I had already lost most of the grapes. Have had a problem with japanese beetles. The vine has full sun all day. I don't especially water it and never have fertilized it. Has always done fine until last few years.
