It arrives here
Atlantic Ocean
Everything that falls here works its way east and north to the Atlantic. It is the drainage that carried the fur trade inland and the log drives back out, and the one Atlantic salmon and American eel still use — the eel travelling the whole length of it to spawn in the Sargasso Sea.

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
Easy ground for most vegetables and fruit. Iron and manganese start to get harder to reach at the top of this band, which shows up as yellowing between the veins on young leaves.
Happy here without a fight
Brassicas, beets, spinach, peas, lilacs, clematis and most herbs. Hydrangeas come out pink.
If you want the rest
Leave it. If acid-lovers are the point, grow them in containers or a made-up bed rather than fighting the whole garden.
Working it
Fine and fertile, holding water better than sand without clay's stickiness. It caps over in heavy rain, so it wants a mulch or a cover crop rather than being left bare.
