We have a large garden with a variety of different coloured Buddleias (9 plus a Globular (Orange balls) type) which attract large quantities of Butterflies and some unusual Moths like the Hummingbird Hawk Moth.

Normally I cut back our Buddleias at the beginning of March but because of the warm weather they haven't dropped their leaves this Winter and have all been in growth mode for a couple of months.

The question therefore is if they are cut-back at the normal time will it harm this years growth ?
