A recent wind storm knocked over our wooden arbor which broke my clematis at about 15” high. Two questions, do you think the stub will regrow? Do you think if I cut the remaining vine at about 6 ft. Then try to reroot in soil? The base is still green.thank you, Gail Baker
It will, definitely, regrow. Pruning is a normal part of maintaining this vine. You can also propagate this by tip cutting. Just cut the vine into 6 to 12 inch segments, and plant them in moist soil using rooting hormone, aspirin, or honey to force rooting. Keep the soil moist but not wet, and not dry either. These can be very easy to grow from cutting.
