Q.Will bark chippings be sufficient to keep clematis roots cool?
I’ve recently planted two clematis plants with a trellis to grow up. I’d like to cover the ground of the beds with bark chippings to reduce weeds and look nicer. Is that going to be sufficient to protect the root of the clematis or should I add stones as well?
Thank you
Mulch is a great way to control moisture, keep roots cool and keep down weeds.
Keep the mulch back from the base of the plant about 6 inches; this prevents diseases.
A layer of about 4 to 6 inches of mulch will be sufficient.
A like to say 'plant a Clematis with its roots in the shade and its flowers in the sun'.
