The other confusing part about Clematis was the pruning. I guess I had been lucky that the first few I bought were types that bloomed on new wood. So, at the end of summer I would cut them down and then next summer have lots of blooms. It wasn't until I bought 'Nelly Moser' that I finally learned about the correct pruning times. I couldn't figure out why I would only get one or two blooms on it.
Now I find that I've accumulated 14 and except for a few, it's hard to remember when to prune each one. I've written out lists looked up each one and written down the pruning time. Then I've lost each list and had to start over again the next year. I thought I would use this post to keep track of my Clematis as well as explain a little about when each type is pruned.
Type 1 or A are Spring bloomers and require no pruning unless you would like to thin them or cut out dead vines.
Clematis armandii is one I had but unfortunately decided to move last summer and it didn't make it. I'm sure I'll be adding another this year, maybe the pink 'Apple Blossom' variety.
'Southern Cross' a new one last year which is zone 8 - 9, so I may be pushing it a little, crossing my fingers it makes it.
Type 2 or B is divided into two groups
B1 usually bloom May - June on previous growth, and may have a second smaller flush of flowers later in summer on current growth.
'Josephine' - grows happily in a container on my deck
B2 bloom on last years and current growth usually continuously from June - September. Pruning should take place late winter and just cutting out tangled or dead vines.
Type 3 or C bloom on current wood only. These should be pruned as close to the ground as possible to the first two sets of buds. These bloom during the summer and are fast growing.
'Alionushka' - easy care and blooms great every year
'Etoille Violette' (viticella) - blooms like crazy in hot side yard
'Jackmanii superba' - as easy as they get and blooms like crazy
viticella) - new last summer, few little blooms
'Ville de Lyon' - another very easy one that has huge flowers
'Ville de Lyon'
I'm sure my list will continue to grow, especially since I have 3 already on my wish list. I fertilize Clematis by putting new compost around them in the Spring. If you have any other tips about Clematis I'd love to hear them as well.
