S O S how to prune Philadelphus
Help please! I have a large type Philadelphus - in fact it is too large for where I planted it. It is now 4 years old and becuse of hubby 'tidying it up' at the wront times this is the first year it has flowered. Beautiful. But from about 5' it has put on another 3' of growth. Should I cut back this new growth now. I know it will flower on growth it does this year BUT I dont want it to get any bigger. Assistance please. Many thanks.
