Bleeding grapes
No matter how well you plan, things can go slightly wrong and there was a disaster this year that meant that I had to cut back the decades-old grape vines a month ago, when they had started to sprout. Now anyone that knows anything about gardening knows that you don’t prune grapes when they have started to grow in spring. You prune them in the depths of winter or they will bleed. As expected, once they were cut back they started to bleed. In fact they didn’t so much drip sap as pour! Now, a month later, they have just about stopped but the cut surfaces are now covered in mould – not pleasant.
The reason why you shouldn’t prune grapes in spring – they bleed
Fortunately, the shoots growing from the old vine are doing well and there are flower clusters forming and I will be able to pinch out the tips soon. But I will take one shoot from the end of the old vines to train along the wires to replace the old rod that had to be cut away. In two years we will be back to normal – I hope!
Fortunately the vines have continued to grow and I will retrain the main rods in this summer while the lower part of the vines should still crop

well done to save the vines
Yes they were a bit sad for a while but they will be ok in the end
