Question
I have a clematis which is about 4 years old and never bloomed.  I have another one planted beside it and it blooms, this is newer.  The original one, I have lost the tag for it so I don't know the pruning type.  Right now it is full of foliage over the arbor.  In the past I have pruned it back in the winter but this last winter I left the vines and it shot from there. I thought I might find the leaf on the internet but to no avail.  The leaf from the stem is rounded for 1 1/2 inch, goes in and then up for up for 1/2 inch, goes in and then up for one inch.  I am an avid gardener, living near Vancouver BC, zone 5 and would sure like to know what to do.  I'm stumped.

Answer
Hi Jacquie,
Thanx for your question.  I would let the vine continue to grow and not prune anything.  It may be a late bloomer.  Also, feed your plant a low nitrogen fertilizer such as a 5-10-10.  Typically, rose food is good for clematis.  Mulch the roots to keep them cool.  Clematis like cool roots.  Make sure your plant is getting at least 6 hours of full sun.  I hope this helps.
