Early every spring before the sap rises we cut back our grape vines. This gets rid of all that dead wood making way for the new growth. Above you can see before pruning.
And in this picture the after. This allows more air circulation and sunlight penetration reducing fungal diseases.
Now that they are all pruned they will be top dressed with compost and manure and a fresh layer of straw mulch to help retain moisture and discourage weeds.
Most years we are able to grow a pretty decent grape harvest with no spraying at all.
Now if I was really on top of things I would be making some grape vine baskets with these vines. Just what I need another project/hobby!
