I've got a shrubby, semi trailing Potentilla, rich yellow flowers, 2 years old, planted in a raised bed full sun west-facing.
Stupidly misplaced the name tag and can't remember which kind it is exactly, nor when to prune it.
Last year I think I pruned it mid spring and it produced a measly amount of flowers late Summer.
Haven't touched it yet this year - too nervous until you experts out there give me some advice!
Is this a kind that flowers on the current year's growth, so needs pruning BEFORE flowering, or does it flower on the old wood only (?no pruning required?)
RHS is a bit vague - just tells me that Potentillas evn if deciduous (mine is) are Pruning Group 10 - er, yeah! Means nothing to me
