Newly found grapes what to do
We bought a house recently and realized we have grapes growing. They are in a space 8x50 ft. There are not on any supports just laying on the ground. Some of the branches off the main trunks have started to put down roots. Can I up root those and tried to put them on trellises. Of course leaving the main root structure intact.
I have no experience with growing grapes so any advice would be helpful.
