Hefty buddleia and small rose bush

Wonderful weather but time moves on! Please can someone kindly tell me how to decrease the height and garth of my wonderful buddleia davidi that has outgrown its space? I actually have three and they have become like small trees. There is thick trunk like stem near the ground and to about 3 ft. I am thinking of cutting some 'trunk' back to decrease the garth but can I cut right down almost to the earth (not quite!) and will this help to produce smaller, more compact buddleias? I hope so!

Also I have a small 'wild type' ballerina pink rose, one of a number, which I meant to transplant a foot to fit in with the rest of the design, but did not get around to it. Is it too late? Two others were moved without problem last year but not at this time. The roses have some beginning leaves and buds. I have another, which only has one or two and I could transplant that one instead.

Thank you so much!

Thanks for the recommendation. Would I kill the buddleia if I cut it right back to almost the ground - would it sprout again from thick trunk??

Thanks so much!

Buzz is really good for taking cuttings from too, I took six from the freebies in GW mag last year, and I am new to taking cuttings, so if I can anyone can!

Thank you! Yes, I imagine so as the buddleias spread themselves around the garden last year!

Does anyone have any advice re the rose?

I would have thought that it would be ok to move it now before it really gets going. You can buy and plant potted up roses now, so really if you get a good rootball,  prepare the new hole well, and water before and after moving, I can't see a problem.

Brilliant! Thank you so much - I will try and save waiting for the Autumn. I read that evergreens could be moved in March; I have a largish hebe - would it also be alright to move this now  a couple of feet?
