Thanks to a generous sun, the vine flower appeared around June the 6th.The stamens (male organ) and the pistils (female organ) are out. The vine is hermaphrodite, it doesn’t need bees or birds, it will self-pollinate to form the first berries. It’s a very delicate and complex time.
Once the stamens and pistils came in contact this is the fruit set :The berries will get bigger and bigger, from the size of peas to the current grape size in July. It’s the “cluster control”. And then let be patient !
