Problems with clematis on other plants
I have about 50 clematis plants, so I'm not a total newbie, nor do I consider myself an expert by any means, but I have had problems growing clems on plants. I brought this up when Miguel was still with us, and he said he'd never had a problem, but I have. I have bare spots in a large juniper and think I killed a dwarf arctic willow by growing clems on them that then shaded them out. This year, I have decided to take Huldine out of a crabapple because I notice the crab has no leaves right where the clem was, and my forsythia bloomed poorly this year, again where Mme. Julia Correvon and Betty Corning grew last year. I am now only going to grow clems on trellises and obelisks. For anyone who can grow clems up other plants, do you have any secrets to impart? Do you cut them off the plants after blooming? Could it have anything to do with my cold zone 5 location? Are the plants I'm choosing unsuitable? Thanks for any feedback.
