Terraced border at Blenheim

Much of this slope is being managed by rows of stones so that each section of soil will have a reduced slope. Trailing plants like Aubretia can be planted behind the stones.

What’s in an image? Sometimes quite a lot, more than meets the eye. I’m posting an image every few days.

What to do with a sloping garden

Click to enlarge

There are many things that need managing in gardens great and small; one of these things is a slope. If your garden is on a hillside and the slope is steep, you will need to create a winding path to exchange steepness for distance, or as an alternative, build some steps. If you have a sloping flower bed you can make a bank and plant ground cover plants to stabilise the soil and reduce erosion, or you could build a rock garden.

Terracing

In this photo, you can see the initial phase in construction of a third way of dealing with a sloping border – a terraced border. Much of this slope is being managed by rows of stones so that each section of soil will have a reduced slope. Trailing plants like Aubretia can be planted behind the stones, or low shrubs or herbaceous plants could be planted in the lower tiers with tall plants and small trees such as Acer cultivars at the back. The terraced area in the photo will look lovely as it becomes established with some mature plants. Perhaps I’ll go back in future to take more photos for comparison.

A rockery

A rockery would be designed differently, the stones would be carefully placed in a naturalistic way with alpines growing amongst them, but not hiding them. Again, taller bushes and small trees would fit well at the top, concealing the fact the the ‘outcrop’ of rock is of limited height. A well-built rockery should respect overall angles of bedding planes, even though no such planes really exist. But making it look as if they do can give a fine impression of structure. Each stone needs to be angled in two dimensions to fit with angles of all the others. They must all lean backward or forward at the same angle, and they must lie from side to side in agreement as well.

It’s usually best for the stones to lie backwards rather than forwards, they will be much more stable and better supported, but they will also proved better opportunities for planting after the stones are all in place. Careful planting can hide the gaps between some of the stones, giving the appearance of much larger blocks of stone. It’s very convincing if done well!

A hillside

If the garden is large enough, a winding path with several terraced or rockery sections (perhaps both) can be very pleasing. This is a great way of using a hillside, though few of us can afford such an expansive space. But it’s a great idea for shopping centres, university campuses, industrial sites, and parks where there is already a natural slope large enough for this kind of feature.
