Crickey, I didn't realise just how quickly the vines are growing. Look at the 2 pictures of the vineyard. In the first picture, posted only 3 weeks ago, and you can just about see the vines over the guards, and in the latest quite a few are up to the first wire which is 1m above ground, a growth of around 0.6m
I'd better put some more nutrients on them, they really will be needing it growing like that.
