Put the augustus in the middle of your planters, they will be taller than the Munstead. Plant about a foot and a half apart for a nice thick hedge.
Because of our unpredictable weather I prune twice. Once when flowers finished to about an inch below flower stems, then again in spring around end of March beginning of April depending on weather....didn't this year as weather so appalling! Usually I cut then to new growth appearing at bottom of stems so pretty hard back.
I have a lavender hedge getting on for 12 years old now and still looking good
