The Chelsea Chop

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.

Sedum, the Ice Plant, frequently collapses & looks ugly just as it flowers

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 Round in Circles

Designing your own garden is, I think, far trickier than designing someone else’s. One of the problems is that emotion gets in the way. I’m not suggesting that there shouldn’t be passion in design but far too often one is tempted to hang onto things that have no place in the new design, whether it is a plant or a pot – or in this example, far too many pots!Garden Makeover 3a copyright

The garden shown here was quite a good size but difficult for it was on a gentle slope and there was need for a central path to lead to sheds at the far, and lower, end. To avoid splitting the garden in half, large circular stepping stones had been randomly placed but the result was a confusing mish-mash of shapes and plants. The only place the eye focused on was the rotary washing line!Garden Makeover 1c copyright

You don’t need to be a great artist to design a garden. A simple method is to take photographs, turn them into black and white (for colour confuses the eye) and pencil sketch over them. Here, we were quite keen to improve on the circular theme.
The final result was a series of circles, each with a low retaining wall and a step down to allow for the change in level. Trellis was used to screen the sheds. Although the hard landscaping took up more of the garden than before, the remaining planting area was far more useful and could be crammed with plants. The little walls made perfect low seats.Garden Makeover 2c copyrightGarden Makeover 1b copyright

And what happened to all the pots? Most of these were discarded in favour of a large, custom-made, L-shaped timber box. This gave a better space for planting as well as making a feature in its own right. Water-retaining gel crystals were added to the planting soil reducing the need for regular watering.Garden Makeover 3d copyright

We Built a Pond – you can too!

Winter is an ideal time to create a pond and with it fast approaching now is the time to start planning.  Quite probably you have an idea where you want to place it but do think about its position carefully.  Falling leaves from trees is an obvious issue but some others aren’t until it is too late. Water always collects at the given lowest point; a pond perched on top of a mound will look ridiculous so check where the lowest point in your garden is and create the pond there, remodelling other sections of the garden, if need be, to tie in. bulrush-copyright

With our proposed pond site, we already had a large depression where garden rubbish and junk had been thrown for years.  Now overgrown with scrub, it needed careful clearing, including roots that may have punctured the lining.  If space is tight, the pond should have a planting shelf set several inches below water level, around at least one third of its edge; if space permits a graduated slope to the pond encourages plants to spread more naturally and, to my mind, is preferable.pond-build-1-copyright

If access allows, it is sensible to hire a digger to create the pond for even a small one involves a lot of digging and moving of soil.  In the past, the mound was often left behind with a few rocks, or even worse, bits of broken concrete, to create a rockery.  This very rarely works well and it looks far better to have lawn leading down to the pond with possibly shrubs or other plants surrounding it.  Whatever the choice, it is important to have a seamless transition from water to garden.  Iris work well for this as there are varieties that will grow in shallow water and on the moist soil surrounding it; some reeds, too, will colonise the bank giving the pond that natural look.pond-build-3-copyright

When using a lining it is important to allow a decent overhang onto dry land.  In this photo, the lining has been cut a little on the tight side – the weight of the water pulled the liner down into position; it is better to trim the liner after the pond has filled.  Once that has been done the liner can be disguised by laying turf down the sides to just below water level.  Once grown, it creates a beautifully natural appearance to the pool.pond-lining-2-copyright

In the spring, aquatic plants can be planted.  Oxygenating plants grow below water level and apart from being essential, make good cover for fish and insects from predators.  Marginal plants grow in shallow water and are used for lining the edges of the pool.  A thick planting of these are a good safety measure if small children are likely to visit, although they should never be allowed to do so unsupervised.  Water lilies grow in different depths of water so do make sure that the variety you choose is suitable for the depth of the pond. pond-5-copyright

 

Ponds, however large, never need to be exceptionally deep, rarely more than a metre and can be as little as 50cms.  Smaller ponds benefit from a deeper ‘hole’ so that fish can take shelter from the coldest weather.  It is worth remembering that the larger the pond the easier it is to maintain and keep healthy.  Finally, once the plants have established, fish can be added.  For a wildlife pond, ornamental goldfish should be avoided although some of our smaller native fish can be included.

It is always a surprise at how quickly new plantings grow in a garden and the pond is no exception.  The scars of our pond had healed within months and even after just a couple of years ponds can look as if they have been there for ever.  Now twenty years later, visitors to our garden find it hard to believe that the pond isn’t natural; it abounds with wildlife and there isn’t an inch of black butyl liner to be seen.pond-2-copyright

The pond featured here was built in the large garden of the house that I claim to be my birthright (joke).  Correspondingly, the pond also had to be large but the principles of pond design and placement are the same whatever their size.
