When to prune ?
 

A few weeks ago, I picked up several neglected, root-bound, under-
watered Forsythias for cheap at HD. Now properly planted, they have
recovered nicely. They are very spindly, and I would like to prune
them back to get a nice shape next year. When should I prune? Should
I let them have the rest of this year to recover/get established and
wait til after they flower in the spring, or go ahead and do it this
year before they start to set the flowers in the fall? Thanx.

Since they flower on new growth you might want to wait until next year after they flower or you can try it now. Your choice.
