Andrew,I don't know what the 'professional' method is, but I just snip a few cuttings off, dip them in rooting powder and put them in a pot, around the edge. My favourite one is Hidcote, as I love its deep purply colour.
Jean, that is lovely. I was once given one of these plants, but everytime it gained a new leaf it also lost one and I never could get it to grow any bigger. However you are treating yours, you are certainly doing the right thing!
Certainly made me giggle!
We have a simple framework, with a fine-mesh net over it to keep birds, and cats, from our soft fruit. I have read somewhere about growing strawberry plants in a length of guttering, which can be propped up on supports to keep the slugs off - just an idea.
I love these simple poppy flowers. I have them in my garden, more and more each year, both in yellow and a few in orange. I have never planted them, they just arrived. I agree with Figrat - definitely no need to sow seeds!
I've never grown lavender from seed, as cuttings root very easily. Can you not beg a few snippings from friends and neighbours?
I just chuck old compost from pots onto my flower garden. It all helps to enrich the soil, and to improve the heavy clay.
Can you give us a photo, please? Descriptions are not always helpful.
My first impression was that it was a perennial sweet pea, and not a clematis at all!
Don't forget that small trees can be grown in pots too, and will give your garden some height and help cover those fences.
