Three years ago I planted a Clematis Armandii with the specific purpose of covering a thick black plastic pipe on the back wall of my house.
I wrapped plastic netting round the pipe before planting and the Clematis grew at a fantastic rate and was covered in white flowers a year later.
My problem now though is that the stems growing round the pipe are now bare and all the leaf and flower growth is on the trellis I attached to the wall above.
Is there any way I can encourage the low buds to come into leaf again or is this just a habit of the plant which cannot be controlled.?
Would be so grateful for any advice.
