Isn’t it always the way it goes; you start a project and suddenly you can just see that your scope is too narrow.
I’m afraid I might have to admit that I’ve under-dimensioned the lay-out of the new Sunny Border; now that I’ve dug half of the planned area free of turf it seems quite clear that this won’t make the sort of impact I want it to, regardless of how lush and colourful the plants decide to grow.
I might have to double the radius of the semicircle, and this will of course quadruple the area that needs to be cleared. (A = π x r2 for a circle if I remember correctly – when I was a kid we used to always ask our maths teacher “but what will we ever USE this for?”, and I guess he should have just told me that when I started a garden it would be quite handy to know basic geometry… I also use the Pythagorean number sets quite often – a triangle with the lengths 5-4-3 will give you a straight angle since a2=b2+c2.)
Still, I’m making headway, and my back is actually less sore now than it was after I’d dug out the first square meter. My body is getting accustomed to the work, it seems.
I still need to work out how I’m going to dig out the turf around the young clematis. I suspect I might resort to just scraping off the grass and the top roots, lay down a thick layer of cardboard around the plant and then mulch that over with compost so it doesn’t show. It won’t remove all the roots but it should at least limit the amount of grass that manages to get through to the surface.
Plastic would probably be more efficient, but I think I’ve made enough concessions by deciding on a vertical 8-inch corrugated plastic barrier between the border and the lawn. The cardboard will decompose naturally and actually add something positive to the soil, whereas a sheet of plastic around the clematis would just be an atrocity that will disintegrate but not decompose, leaving me with small bits of plastic in the soil for years to come. (At least the plastic barrier towards the lawn has an expected durability of 5 years, possibly more, given that it will be completely covered on both sides, and when it does start to disintegrate the border should be established enough that I can maintain the edge by cutting it with a spade every spring.)
Anyway, enough of a break; back to the garden – and the heavy work – I go!
(EDIT: And now it started raining – just a slight drizzle, but enough to turn the soil into mud if I walk around digging. Armchair gardening it is for now!)
