Clump­ing se­dum

Amateur Gardening - - Pick Of The Very Best -

QHow can I keep my se­dum in a well-shaped clump? Denise Jackson, Tyne and Wear

AThis lovely plant is a clump-form­ing peren­nial. Af­ter three-five years the stems be­come over­crowded, thin and spindly, which makes the stems prone to col­laps­ing out­wards.

To en­cour­age thicker, stur­dier growth, lift and di­vide your plant ev­ery three-five years in spring. Grow in free-drain­ing soil in full sun.

Se­dum spectabile re­sponds well to the ‘Chelsea Chop’. Cut back all the stems by up to half at the end of May, which will re­sult in stur­dier plants that do not re­quire stak­ing.

Di­vide se­dums ev­ery few years
