Muscat grape disease (happens every year!) I'm devastated !

OMG ! Please help, my beautiful Muscat grapes get this disease every year ! They are in a 'half-barrel' type container, 3 containers and all three get this every year. I purchased The grape vines at least 5 years ago from a local very reputable family nursery. I'm now thinking that it is the soil that is contaminated ?! How can I send you a few pictures???

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?
