Can someone please diagnose the problem with my Wine and Rose Weigelas?

Question

I have 6 and they all show the same stunted growth on some branches. The first photo shows the weigela that shows the most deformity. Thanks for any help!

Answer 1

This can often be attributed to poorly draining soils and unbalanced pH. You can correct this by applying a top dress of dolomitic lime, and worm castings, as well as live worms if possible.
