Digging beds from scratch - how deep and what soil?
Hello everyone
We are renovating our garden. The previous owner covered half the garden in 6" deep concrete and the other half in paving slabs (the builders are outside digging it all up as I type, ready to be loaded into a skip on Monday).
Because of all this, we are essentially starting a garden on a bare site. We will be laying some turf and digging beds. We won't be growing veggies in the beds, just shrubs, a few climbers, etc. The 'soil' beneath the concrete and paving is very clay-rich. My question is how deep should we make the beds and what soil/compost should we buy to fill the beds? I'm staggered by the cost of topsoil but we do want the garden to actually grow, so we are prepared to invest the money.
As far as the lawn is concerned, my understanding is that the topsoil needs to be at least 6" deep, correct me if I'm wrong!
Thanks all.

Dig your beds over about two spades depth, break up any solid layer of clay underneath with your fork , and incorporate lots of well rotted farm yard manure and/or mushroom compost into the soil. No need to buy topsoil - over the years add a good mulch of compost and/or well rotted FYM every autumn and that, combined with the clay, will give you a lovely fertile soil. Roses in particular will absolutely love it.

Okay, great, thank you so much. That's something of a relief, it takes a little off the cost. What sort of clay soil:compost ration are we aiming for?
I've never worked out how much I use, but what I'd do is dig over the beds, then cover the beds with a two or three inches of your organic matter (manure/compost etc) and fork it in.
This sounds a great project. Hope you're going to show us some pictures as you go alone
Hope someone's going to come along with advice re your lawn .... if they don't I'll give someone a nudge

Thank you Dove, that's so kind. It's really quite nerve-racking, neither one of us has much experience in gardening. I had a small garden before I moved here, and did a little with it, to the best of my (limited) ability. I've spent quite a bit of time drawing up a shortlist of plants, so I have a rough idea of what is being planted where. Slightly terrified!
Hi Patiate good advise here is free BUT paving slabs arnt they are very expensive and great for putting sheds etc on,so how about giving em away ,go down you local and shout does anybody want slabs for a pint and watch out for the rush good luck with garden mateys
Yes, we'll probably keep some as foundations for the new shed which is going next to some decking and will probably need raising up a little so that the door can open over the top of the decking. We could advertise the rest on Freecycle or Gumtree, I'm quite happy for people to take what they want. Might even leave a couple of small stacks on our driveway with a notice telling people to take what they want.
As for draining, do we need to lay something else underneath the topsoil? Something like sand, gravel?
Pest pits are always useful and serve many purposes - one on the front drive for unwanted callers, chuggers, baliffs etc - one in the back garden for vine weevils, New Zealand flatworms etc .
However, my guess is that Edd means you to dig 'a test pit'

Very likely Edd

For the lawn area, if you can rotovate or fork in about 3 inch of compost, or well rotted FYM into the top 6 inches of clay, that will do. My brother bought a house with a lawn of turf laid over clay. The turves curled up like old sandwiches. He stripped the lot, pinched the entire contents of my mums compost heap, all the used tomato compost etc, and rotovated it in. He then seeded it, and now has a nice lawn.
To plant shrubs, mix organic stuff as above with the clay in a 50 /50 mix, and make the hole for the root ball at least twice as big as the plant root ball. Otherwise you will plant into a sump and it may rot in wet weather.
Clay can be very productive if you can get enough organic matter into it.
My only tip is that you may need to check drainage over the next year and may need to put in a drain or soak away
best of luck
