Hi,

We need to completely remove several Buddleia davidii bushes. These are
about ten years old, have been annually cut back, including just now - i.e.
prior to pending destruction.

Do I need to dig all the roots up, or is there an easier way to kill them
with out polluting the soil or unduly disturbing adjacent shrubs?

We aim to recondition the soil and replant there immediately afterwards if
possible.

Thanks,

Keith
