Gypsum for clay soil

Unused plaster will bind the soil, used lumps wont. Run it through a cement mixer and a couple of rocks as a ball mill. So long as you crunch it down enough to go through a sieve, it's fine. Even just soaking it in an excess of water would be enough (this is plaster, not cement). I wouldn't add "rottable garbage" to soil either, it's much better to rot this down separately. Otherwise you'll be short of nitrogen and lawns in particular would suffer badly. |

So they say, but I've not seen this happen in practice. If you added wood shavings or plenty of paper I daresay it would. NT |

But in general, yes. 3 years and then apply compost. You can hurry it along, but why bother? Gardening is a long term investment. NT |
