Drag the spade down, or tap Dig deeper, through the leaves, the living topsoil and the subsoil, all the way to the bedrock that is really down there.

Under the grass is a whole hidden world. Drag the spade down — or press Dig deeper — to find out what is down there.

It takes hundreds of years to make one centimetre of topsoil. The depths are typical — every place is different — and the ruler is squashed at the bottom so the rock fits on the screen.
Say it like this
Go outside: Dig a small hole in the garden and count how many worms live in one shovelful — then put them all back and fill it in.

of the ten-year median for this date · 4.8 m³/s against 14.9 normally
very lowWell below normal for the date. Fish crowd into whatever deep, cool water is left, which makes them findable and also makes them fragile — a fish played hard in warm shallow water often does not recover. It is rising — about 114% more water by the end of the week.

Bedrock and soil figures are modelled from national geological surveys and global soil mapping, at a resolution of a few hundred metres — right for the shape of a district, not for a particular garden. River discharge is modelled, not gauged. For anything that matters, dig a hole and look.

The soil it made
What that means
The sweet spot for a vegetable garden. Nearly every nutrient is at its most available somewhere in this band, which is why it is the number every soil guide tells you to aim at.
Happy here without a fight
Almost everything: tomatoes, beans, squash, lettuce, apples, most perennials and most lawn grasses.
If you want the rest
Nothing needed. Compost keeps it here; heavy lime would push it past useful.
Working it
Water runs straight through, so it dries fast and warms early — you can work it days after rain and sow ahead of heavier ground, but it needs watering and feeding more often because both wash out.
