Glasshouse grape vine

Tom O\’Connell asked 8 years ago

I sowed a vine about three years ago, rooted outside and trained it inside the glasshouse. There has been plenty of growth and flowers. However towards the end of June the flowers fail to develope further- no obvious signs of pests or disease. I have used no spray to date. What is the cause of this? Should I now spray for mildew and maybe be more active with regular prunning?

If there is no sign of mildew, there is no need to spray.

Young vines tends to be vigorous and often do not form fruit in the early years, when expansion growth is the priority.

Do not over-feed and allow it to settle into a flowering and fruiting pattern.
