Improving Drainage on Allotment
My allotment has a severe drainage problem so I'm building raised beds,
which I hope will help. As well as manure and compost, I want to add something else to improve drainage. It's clay soil. What should I use -- pea gravel or sand (builders sand?) or something else? Thanks. |

If so, I think that the manure will improve your soil and if you keep adding it on top years after years you'll end up with fantastic beds. I wouldn't start using gravel or sand because you don't know what you'll grow say in 2 years time. It depends on your rotation plan but also what you want to grow. I had a corner on my lotty so compact with clay I thought nothing would ever grow. I've added manure for 2 years - then potatoes and now perhaps 2 spit down it is clay but there's enough manured top soil to grow my leeks this year, garlic and kale walking sticks :o) |

Topsoil. http://www.onlineturf.com/partners/onlinesoil/index.asp Maybe cheaper from builders merchants or similar locally to you. Cheaper per unit in quantity. Everything depends on what you (or other allotment holders if they're at all interested) want to spend. |
