Out of all the berries/fruits a human can eat, I give grapes the number one award. They are low enough to pick with out a ladder, high enough above the weeds that you don't have to work the soil and they are sweet and taste great...............Grapes have my award for being the number I human food and in season now.
Today I picked 10 gallons off of 2 vines and had also been eating daily for the past 3 weeks and I figure at least 5 gallon are left for the bees, etc... Thats alot of good food for such little effort raising. A good grape vine will last hundreds of years and will grow and grow and you can put a rock over the vine and a new vine will grow roots.
Frozen the grapes are a winter time or next summer cold treat. Makes jelly, juice, etc..and even wine for those that like the taste.
I get tired of fighting weeds, fruits that grow above weeds are ideal, all of them!
