Despite its name, the Chelsea Chop isn’t the latest trend in hair styling although trimming the unruly and the straggly certainly is involved. It is a very simple and straightforward method of cutting back herbaceous* plants which, for some reason, terrifies even the most confident of gardeners.

The only skills required are courage and the knowledge of exactly when to carry out the chop. The latter is simple to calculate and is hinted at by the title of the deed – the week of the Chelsea Flower Show or thereabouts. This year, there have been two hiccups in using this rule: firstly, the show has been moved to autumn because of Covid restrictions and secondly, because spring has been so slow in coming that plants are behind with their growth. As a general rule of thumb, the time for cutting is around the third week of May.

Beloved by bees and butterflies, Sedum – also known as Ice Plants on account of their fleshy, cool-to-the-touch leaves – are the ideal candidate for the chop and one of the most satisfying to do. Inevitably, when left to their own devices, the large, flat flowerheads are too weighty for their stems and they topple over to sprawl across the ground and spoiling an otherwise impressive display.

To make the chop all that has to be done is to cut through every growing stem, thereby reducing the plant’s overall height by half to one-third. Clear away the prunings (which can be added to the compost heap) so as not to attract slugs. There, I told you it was simple!

Although the method sounds and looks drastic the plants quickly recover and make new growth. The end result will be a plant that doesn’t collapse and doesn’t require staking. Admittedly, the flowerheads will be smaller than before but they produce so many more than they would have done left unpruned that the effect is in no way diminished.

This simple pruning technique can be used on a number of other plants too in exactly the same way. The taller achillea, phlox, campanula, asters (michaelmas daisies) and rudbeckias are all good candidates. I have heard of its use on echinacea (cone flower), penstemon and helenium but, in my experience, these are trouble-free plants anyway, so why bother? The secret to good, stress-free gardening practice is to find the balance of what suits you and what suits the plant. The Chelsea Chop on sedum in May prevents an awful lot of stress later in the year!

Going…..


I am often confronted with an area of garden which has been cleared by a client of vegetation for them only to be daunted by the expanse of ‘scorched earth’ that they are left with. The one below, turned out to be one of the biggest challenges to date with the request that the area had the appearance of one large flower border from the house, yet without too much height. The other specification was for there to be a driveway for cars incorporated into it and for it to look traditional – not one of the newer ‘prairie’ styles, the fashion for which has swept Europe in recent years. To make matters worse, in clearing the garden, the contractor had also removed most of the topsoil.
To make the garden more manageable I divided the area up into sections. In the photo below is a new stone path splitting the levels and, to the left, part of the driveway coming in, in an arc. Altogether there were three raised beds, a long border plus the ‘in and out’ driveway and new path running through the whole scheme. Also in the photo is part of the mountain of topsoil that had to be brought in and there is still some turf to be removed. 



Sometimes it seems as if flowers have inspired the sunsets! Here is the rose Rosa x odorata ‘Mutabilis’ trying to outdo another mountain sunset. This rose starts with the most intense pink bud and, as the flower fades, turns to the softest apricot, ending up with this wonderful colour combination.
This old mossy wall was the starting point for a mini parterre – the ‘moss’ is made from the box (boxwood) framework, the ‘stones’ from variegated Iris and Cotton Lavender. The wall reminds me of our garden wall in the secret valley (Sunday 20th September 2009) but this one is in north Wales and is a hard, cool grey and silver granite unlike our soft, mellow Cotswold stone. This planting is tiny compared to the usual grand parterre designs and has been used to link two levels of a small garden. 


So let your imagination take you where it will. Sometimes the combinations don’t work but, more often than not, there will be some exciting discoveries to be made and a lot of fun will be had along the way. And make sure you tell me all about them……
