Plant details

Clematis montana is a vigorous climber that is perfect for covering large supports such as pergolas or walls. From late spring to early summer, it is a sight to behold as it becomes covered in white flowers. Like all early-flowering clematis, it requires little pruning other than the removal of any dead or damaged growth after flowering. Large plants make suddenly die off for no apparent reason. This is usually due to a condition called slime flux. This is caused by an injury to the stem early in the season. The sap leaks out becomes infected with bacteria. Cut out infected stems, pruning back to good wood even if this involves going down to ground level.

Could anyone tell me how to successfully take cuttings from Clematis montana (Elizabeth)? I tried last summer after flowering had finished but failed miserably.


once I have details of all the plants in my garden assembled in the scrapbook is there a way of personalising the jobs to do section to get advise each week about what needs doing with my plants?

I don't know if it will be a success yet but I pruned my montana a couple of weeks ago (long after it finished flowering) and I followed the advice for softwood cuttings. I cut off 4 shoots, trimmed off the leaves back to the lowest leaf node, left about an inch below this and dipped them in rooting powder and just put them in a 4inch pot. I watered them and covered them with a plastic bag secured with an elastic band. So far, 1 has definitely taken as it is growing shoots from the leave node. Will have to wait and see what happens but so far so good
