I am still learning how to prune some pieces in our garden and had a couple questions. I've never pruned our clematis (blooms in late Apr/May). I've read that in the late winter (soon, I suspect) I should cut it to the ground and it won't bloom this year, but next year will be amazing. Does that sound right? How close to the ground should I cut it? Also, we planted irises last fall and less than half bloomed. I realized they are probably establishing their root systems. Should the greens be cut back at all? And if so, what time of year and how far?
Clematis can be bloomed in the water - February or after bloom.
Usually leave at leas 6-8 inches above ground. Feb. prune reduces winter damage.
Most iris, just leave. No pruning needed. Every 3-5 years break up the massive root ball and replant.
