I have a Jackmanii clematis that has been in the dirt for 20 years or so. Back then, this plant was the most expensive plant I had ever bought. I followed planting instructions to the letter, and splurged on amendments. I put it right by the front door. I felt like a real gardener when it grew up it's trellis, as it grew huge and heavily covered with flowers most of the summer.
But then, when it was time to cut it back, I was afraid was the wrong time or that I would cut too low, or too high, and lose the plant. I was too attached to it, so I put it off.
The truth is, this year is the first time this tolerant plant has had a hair cut, ever! Now there is an unruly thick tangle of old canes around 3 feet wide and 1 foot deep, at the front door looking pretty shabby. I can live with it if it's best for the plant, but I could sure use some mentoring. Am I supposed to thin the old canes out. I would like it to be a little more under control.
It cannot be divided, can it?
There are two young canes that are about 2 feet from the main plant. Can this be dug and moved for a new plant?
How many vines do you keep when the growing season starts in spring from your Jackmanii? Any tips for this cowardly clematis grower will be more help than I can say. Thanks. There are some beautiful clematis grown here, guys!
