Clematis question
Comments (5)You've received good advice from the above posters. Keep in mind that plants are normally dormant for at least part of the cold season in any climate zone. One of the clematis is putting out a lot of new growth. My question is do clematis require a period of dormancy to do well in the spring? Chances are it's putting out new growth because it's indoors which isn't normal (or optimal) for the plant. Perennials, including clematis, go dormant in winter based on climatic conditions affected by hours of daylight + air/soil temperature. Indoor temperatures + artificial light don't replicate seasonal growing conditions. To answer your question: I'm in a much colder zone but it has been my observation that clematis (like other perennials) DOES need a period of dormancy as part of its natural growing cycle. I would echo Ken and recommend you move the plants to a garage/sheltered carport and let them do what comes naturally. In my experience, that's generally what works best. The new growth that's being produced by one plant may or may not survive but should not sound the death knell for the plant once it has a chance to establish a natural & optimal growing cycle....See Moresilly clematis question!
Comments (10)I would take any zone ratings for clematis, especially if they come from observations made by the British, with a grain of salt since their winters can be quite different than ours here in most parts of the US. The exact hardiness ratings of most clematis are not known with any certainty and their hardiness ratings may vary within any given gardening zone based on the winter conditions (say a zone 6 where it stays cold most of the winter vs. a zone 6 where the temperatures vacillate over the course of the winter). COTW is performing a survey to get the hardiness ratings/survivability of clematis from gardening zones around the world to help put some more data together on this subject. Clematis florida 'Sieboldii' is grown by friends in Michigan with no problems and the Toomey and Leeds book says it can be hardy to zone 6. Here in my zone 7a garden I had it survive winters quite nicely but the main problem with it was that it wilted several years in a row right as it was starting to bloom so it was removed from its place in the garden. Clematis florida 'Plena' is a sport of C. florida 'Sieboldii' and the Toomey and Leeds book says it is hardy in zones 7-9. Whether is would survive in your Michigan garden is uncertain but the only sure way to know for certain is to try it and see how it goes. There does seem to be confusion out there about the pruning types that C. florida the species and any of its cultivars fall into since Toomey and Leeds Encyclopedia lists the species as a type 2 and COTW lists it as a type 3, the Toomey and Leeds book says that Sieboldii can be treated as a type 2 or 3 and COTW lists it as a type 3, and the Toomey and Leeds book lists florida Plena as a type 2 and COTW has it is a type 3. Bottom line is that regardless of the pruning group a clematis may fall into, the hardiness ratings are not know with certainty, the only way to know if it will survive in your garden is to try it, and the fun in gardening is finding out what works and doesn't in your own individual microclimate. I know that I have listed this before but the owner of Seneca Hills Perennials, Ellen Hornig, sums it up best about using the gardening zones ratings as an indication of whether a plant will survive and flourish in your garden or not. See the link below and the section entitled Plant Hardiness concerning this. Here is a link that might be useful: Take on Plant Hardiness Ratings...See Moreplanting clematis question
Comments (5)Bob suggested a gallon nursery pot. This is what many of us use when we are starting out with either very small starts (i.e., clems in 4" pots) or bare roots (if we can't resist). Use a good quality potting mix, plant the vine deeply in the pot (so the stem is buried about 2" or so) and water and care for through the growing season. By fall, the roots should have filled the container and the vine large enough to plant out safely. Very small clematis plants are just very vulnerable to the big, bad world :-) Too easy for those fragile stems to get damaged either by critters or mechanical damage, too easy to overlook for proper watering and too easy for them to get overwhelmed or smothered by other, larger plants. Growing them on for a season gives them a bit of a headstart and a fighting chance. And as you might have guessed, buying clems as bare root starts is a risky proposition. In fact, I'd expand that to any type of perennial. There is just no way to ensure that these have been harvested and stored properly so that roots have not dried out or allowed to rot in a too moist storage medium. If the start is showing some signs of new growth - like some green shoots pushing through - that's a good sign. But pot it up ASAP....See MoreRooting Clematis Question?
Comments (5)Well I would give it a little tug to see if it was rooted. I use large clear bags and would open the top of the bag first for a day or so and then if it seemed ok would take it out and grow it on, in its pot. Actually I usually take the pot that the new plant is in and bury it in my garden in the fall so that the roots are not disturbed. Last summer I had a new rooted clematis that was growing fine so decided to plant it in the garden. It didn't come back this year so the rooted cutting of the same clematis will be left in its pot and buried in the garden this fall. Anyway thats my 2 cents for what its worth....See Moreerasmus_gw
