Hi again everyone!
Thank you for all your valuable advice and such an interesting debate to follow.
A quick update - I spread the soil out for a day or two (much to the excitement of my two jack russells!) then used it to top up a depleted border that had had elderly lavender in it for many years (now removed and I'm questionning whether to add it to the compost heap).
As a stop gap before I think of something more dramatic to do I have planted the border up with pretty bedding plants (with the help of lovely hubby) and have stood back to see what happens.
Everything is healthy so far, early days though. I have since found one VW grub which was unceremoniously squashed!
