Building the Colour Wheel Beds

We took a break from the pond, today, and have spent the day, mostly, moving topsoil around. First thing, a delivery of 6m³ of topsoil arrived from the ever-dependable Tommy Topsoil. Unfortunately, the ground's still pretty wet, so it couldn't all be delivered onto the access ramp into the garden, and two-thirds are on the driveway, instead, which means barrowing it further. Never mind.

Before getting the topsoil moved, though, we first marked out the edges of the new beds in the corner 'Colour Wheel' garden. For this, I bought hand-cleft chestnut stakes, 15" long, which we've put in the ground every 2'. Between these, we've woven cleft chestnut laths—they're usually used to create a matrix onto which lime plaster is applied, in restoration work, but they've worked beautifully here, four courses high, to make 6" edges/retaining walls.

We've then barrowed in topsoil, to cover the soil we've moved from digging the pond. It's actually reasonably good, but a couple of inches of new topsoil will, if nothing else, be less prone to weed germination, and will help to gradually enrich and build the soil.

Once the four new beds were made and topped up, we had enough stakes to mark the intersections of the edging in the herb garden, which is, following Saturday's work, now twice as large. That, in combination with some sticks marking the edges (as well as the intersections), means that the layout is a lot clearer. We've added topsoil here, too, to the squares that will be planted, but not to the areas that will form a path. We still need to decide on a planting plan for the edges: our original plan of box made way to a combination of box, lavender and apples; and then to lavender and apples; it might yet become just step-over apples.

The other place we've moved topsoil to is the vegetable beds, which need an annual topping up. Still need to spread it around, but it's heaped in roughly the right places.
