Remove Last Year’s Growth
Can you please tell me if I should remove last year's growth from red hot pokers? At the moment I have them tied up from ground. House area Dorset.

You can trim back foliage as it begins to decline or any old growth, but don't cut it back entirely. Leaves a few inches of foliage on the plants. Also mulch around them both to conserve moisture in warm temps and protect the plant in cold.
