I have a medium sized Weigela bush in my garden. Can anyone advise me on how best to prune it, when to prune it and how often?
There is lots of new green growth on the tips of the stems that flowered this year. Does the plant flower from there next year?
Also, this picture shows the main "trunk" (the thicker upright branches) of the bush. Do I prune back to that or do I also prune that part?
The bush is quite old and I've never really done anything with it so I'd appreciate any advice you can offer!
