After the spring flush, the weigela just sort of hunkers down for the rest of the year. And in this case, gets badly burned by the sun. I’m pruning here to remove the burned leaves, but also to try and open the structure a bit to make it less of a bouquet.
I expect this will grow back strongly over the next two months. I’m hoping that I’ll get more ramification at the edges, rather than filling in solidly.
