Hello! Planted an Endless Summer, Blue Billow, Lady in Red, and several paniculatas last fall. All are doing well. Question is, Lady in Red has old shoots that haven't budded - should I prune these? I have cut the paniculatas to about 12" - is this ok or should I prune back more? RE: fertilizing - I planted them in good soil - I always use Leafgro - and do not plan to fertilize - is this correct? Also planted an "Alice" oakleaf and while my old Tardiva and another oakleaf oare budding, the new Alice is not. It was a one gallon sized plant. Should I call the company I bought it from - White Flower Farm - and request a replacement? Thanks.
