Hi. I have just moved into a new home in Norfolk where there is a hedge of Spirea Billardii of about 6-7feet tall. My gardening books say that I should prune this in early spring to just above ground level and that t will flower on the new growth of this year. My question is - will it grow back to 6-7feet tall in this one season. If not, then how do I prune it to maintain a nice flowering 6-7 foot hedge please. I would be grateful for any help.
