Hello, I have a mature wisteria with several limbs coming off it. I've grown it over a pergola where the old wood is. I've encouraged it to grow in another direction and it is doing well, blossoms well for the last 2 years. The main limb is about 4 inches thick at the base growing over pergola, and the limb in the other direction is 1 inch.

Question: How do I discourage growth over pergola and encourage more growth in the other direction without harming it?

Your thoughts would be appreciated, many thanks, Andy.



If you no longer want any growth over the pergola, the simplest solution is to cut off the 4 inch main stem, at an angle to allow rain to run off, as low down as you can - but not now. It's a bit late this year, but a good time to do it would be when the plant is dormant, in winter, or in spring.
