How gradually should I let my beach hedge grow from 4’ to 8’?

Question

I don’t want it to become too leggy. It’s a mature hedge that has been 4’ for years. I’ve a feeling that I shouldn’t let it grow unhindered in just 1 or 2 years, so how gradual would you suggest?

Answer 1

You might try skipping the August trim and see how fast it grows. Then in February, give it a trim to tidy it up and encourage more growth. Here is more:
