Hi

What's the panel's advice on the best time of year for cutting back budleja?

I've previously read advice of 'immediately after flowering' (about now) and
an alternative view of 'around February'.

I feel that the plants are so vigorous that to cut back now would result in
immediate re-growth that could suffer during the winter frosts,
alternatively to leave it until February could mean they don't have
sufficient time to grow back for next season's flowering.

Any advice?

Many thanks in advance

Paul
