Deutzia & Weigela

Question

These shrubs are 10 ft tall. Very woody with foliage only at the top. I’d like to try & rejuvenate them.
How & when would be best to do it? Thanks.

Answer 1

These are both strong species, and I think you'll be very pleased with the results of a good hard pruning. Here's a general article on pruning: https://www.gardeningknowhow.com/ornamental/shrubs/shgen/rejuvenation-pruning-tips.htm
and an article on weigelia pruning: https://www.gardeningknowhow.com/ornamental/shrubs/weigela/pruning-weigela.htm
Treat the deutzia the same way.
