Last year, I planted 4 rhizomes...on the north side of my property, on a trellis that's in partial shade. Obviously, not much happened. They got big enough to climb the trellis, but the partial shade prevented much else.
This year, I'm planning on getting better results. We have a vegetable garden on the south wall of our house which gets full sun. I was thinking that I'd plant the rhizomes at the outer edge of the garden (which is about 4' from the house), attach one end of the twine to the ground, and attach the other end to the gable-end rake of the house, which is about 15-18' above ground level...thus creating a diagonal (probably 70º) line for them to run up.
Here's my question: I ordered 4 new rhizomes the other day from Midwest. Should I plant these new rhizomes in the new location, and leave the old ones where they are? Or should I move the old ones over to the new sunny location too? Will digging up the existing ones and replanting them lessen their success this year?
