So about 3 weeks ago I clipped the top of my hop bine at harvest and threw it into a small vase of water to see if it would root. Sure enough it started to grow some roots. Now my question is can I transplant this into soil and should it grow?
Yes. I've been doing it with all my cuttings this summer. It's called propagation I believe. You can buy hormones from garden stores to help it root. I'm having trouble with centennial but Chinook have taken off...
