If you’re a real gardener then the chances are instead of hobnobbing it around the Chelsea flower show with the madding crowds, you will be spending a solitary afternoon on your knee pads preparing for a glorious late Summer of colourful Sedums in your Garden!
This year I’m giving Chelsea the chop, with this mild Winter and late Spring false leading to a cool shower in May. The plants in the garden I manage have finally caught up and in need of support. Fortunately, with some fore-thought I had invested in some rather luxurious plant supports that are doing the trick and saving a lot of time with bamboo canes and garden twine.
Not all perennials lend themselves to staking, preferring instead to flop over your garden path or neighbouring herbaceous plants without a second thought. Often these plants have lush vegetation and heavy flowers that the stems can simply not support , crashing to the floor under the weight of flowers and their buds.
That why real gardeners are giving the Chelsea chop, typically associated with mid-May and around the time of the Chelsea flower show, careful removing a third of the lush rich growth of perennials like Sedums and newly classified Hylotelephium, encourages these stems to delay flowering. Instead of rushing to produce heavy flowering bracts the sedum concentrates it’s energy on producing multi-stemmed leafy shots which in time will develop flowering heads of their own.
This selective pruning will delay flowering by a few weeks and give the plant a chance to produce a tighter, denser more rounded form capable of supporting the masses of flowers so loved by gardeners and butterflies alike.
