buddleia rootstock (Newbold Verdon LE9)

Purple-flowering buddleia that's been cut back from 5ft to just above the roots, so easier to dig up & transport. It'll grow back up quickly if transplanted; 2nd photo shows it flowering in September this year. Help with digging up would be useful (I'm 87) but given 2 days' notice I could have it ready to go. I'll be ditching it next week & killing the root if nobody wants it.
