Hi there,
Late this winter we built 6 new 5′ x 15′ raised beds created on what was previously pasture land, and filled with 10 inches depth of shipped in fresh compost (10 tonnes in all). Although – seems I wasn’t thorough enough with my removal of docks! A couple of the beds are now constantly providing a fresh supply of dock leaves.
I’m cutting them out – like asparagus – as deep as I can – but the beds are already planted with Asparagus and onions, so I’m not keen on removing all 10 inches of growing medium to get at the original ‘root’ system.
Will concerted regular removal of the leaves weaken them eventually? Or is it a losing battle and I should dig out the mulch and remove the roots?
