Weigela isn’t growing right
Last spring I planted a two gallon weigela and it seemed to be doing well but this spring I didn't get any new growth from the old branches. The new growth came up from the bottom, kinda like a rose that has gone wild. Is this normal? It hasn't bloomed. Will it come out of it or is it a lost cause?
Your plant may have been killed off by the winter.
You can trim off of all the dead material and allow the shrub to grow. It may take time for it to become a nice size again.
You also could try to see if the garden center would replace the shrubs. Most garden centers offer a 1 year replacement on shrubs.
Here are a few links for you.
