hi ive a grapevine that I planted last year, the vine has 12 bunches of grapes about the size of peas on. todayive noticed that some of the fruit has "shriveled" up? just wondered if anyone can help?? many thanks
There is something called shanking. If the vines get too much water many of the grapes will fail to develop properly and shrivel up. Take a look at the last one here.
