Do you mean something like a giant decorator's shave hook, which you can draw across the soil to make a V-shaped trench?
Well, that looks very good! Don't forget the watering - it'll drink it now that the sun is strong and the spring breezes are blowing.
Use the right tool?
I'm still using my father's - approx. 70 years old (the hoe, that is).
I've found 'Forest' products to be pretty good.
Hi GHworld, I agree with most others here that you will get a weird visual effect, especially as the warehouse will still be visible to left and right, over your neighbours' gardens.
It probably would prefer to grow a lot bigger in a much bigger place.
If you're unsure about how to deal with the implications of badgers in your garden you can approach Natural England, your local Wildlife Trust or your local badger group (if there is one).
Yes, sorry Deborah, it'll be quite a tough job to do properly.
