Our resident gen-i-us Paul had yet another trick up his sleeve when it came time to put down some berry vines. We planted two terraces with raspberry vines and the third terrace got a blackberry.
After amending the soil in each terrace with some highly fertile compost we positioned two posts on either side. These posts allowed us to string peices of twine between the two creating a place to attach the vines of our newly planted berries. (see below)
Instead of attaching all of the available vines to the makeshift trellis, Paul devised a plan to create new berry vines out of no where for free. It sounded too much like hocus pocus to me but Paul insisted. The technique was to weave any available vine of decent length into the soil and then out again like those computer generated hoax pictures of the Loch Ness Monster (see below).
The idea is that the nodes on the vine that happen to fall underground will put down roots and become a brand new plant.
