Need advice to overwinter baby clematis seedlings
Comments (4)Plant them in the ground. Providing it's a variety that should be expected to be hardy where you are, they should winter over fine - same as the countless self-seeded clematis seedlings that I dig up every year from our yard to give away. This is a question that arises often, but just think about it - if seedlings of perennials were not just as hardy as the perennials themselves (not less hardy than mature plants,as people seem to believe), they simply would not have been able to survive in nature, would have they?...See MoreOverwintering Potted Clematis Indoor and Outdoors
Comments (4)I live in Montreal, Canada where winters can be pretty harsh. We often have a couple of weeks of -25C (-13F) temperatures. I've had 2 clematis in pots since mid 2020. They continue to be in pots as I do not have a sunny spot where I can plant them. One is a "Lady Betty Balfour Clematis" (Zone 4). I've lost the label of the other one but I think it must be rated for Zone 4. For the last 2 winters I've been moving both of these potted clematis into our garage which stays at ~15 - 18C (59 - 64F). I cutback the clematis when I move them in (around mid Oct when the outside temp is around (12C Max & 4C Min / 54F Max - 39F Min). By mid Jan the clematis start sprouting and since the garage has almost no light, the sprouts are a very pale green - almost white. I bring them out by late April and cut back all the new (whitish) sprouts. Both the clematis start getting new normal green looking sprouts in a couple of weeks and start blooming by late May to mid June. I'm not sure if what I've been doing so far is OK but it seems to work and I plan on doing this again, this winter....See MoreOverwintering Clematis in the house?
Comments (3)JPW, I personally don't like to attempt to overwinter clematis inside the house for the reasons you mentioned with roses above along with the fact that the plants tend to get very leggy unless you have a window that gets lots of direct sunshine. You said that last year when you attempted to overwinter them outside, that all except one died. How big are the pots your clematis are in? How did you attempt to overwinter them outside last year? Did you cluster the pots together in a sheltered location? Did you leave them sitting out in the open where they were exposed to the elements? You could attempt to cluster them together and place some sort of insulating material around the pots such as bales of straw or the like. Even if you had an unheated area where you could store the pots after they had been exposed to sub-freezing temps that took them into dormancy, that would be better as far as I am concerned than attempting to bring them inside the house. Do you have friends with uninsulated garages or even crawlspaces that could store the plants for you?...See MoreOverwintering Clematis in Containers
Comments (2)The temperature is more important than light. You want to keep the plant as cool/cold as possible in your basement, 32-50F would be ideal. You don't want to overwater, but give it a bit of water once every 3 or so weeks. Light isn't necessary if it's truly dormant. Then in the early spring, cut it back and get it outside, gradually exposing it to light....See Moreditas
