Colliery garden preparation/improvement
Hi all,
After a couple of years with just turf, me and the Mrs are trying to get into a bit of gardening. The problem is our house and garden are built on an old spoil heap. The soil is typically clay and extremely black (i.e. coal slag) below about 7". We've started proactively adding compost, sand and organic matter to the 'soil' before thinking of planting, to improve our situation. Are there any other tricks that you can recommend to make this a decent place to grow 'things' or are am I being too pessimistic about our chances ? All suggestions gratefully received. For climate purposes we are just south of Edinburgh, if that has any bearing on things. Cheers, Keith |

For climate purposes we are just south of Edinburgh, if that has any bearing on things. I'm talking theoretically, as I haven't done it. I have done several years' gardening on a very thin soil layer, though, and had no serious problems. You're doing all the right things. I'd carry on adding all the good stuff you can get, and avoid digging too deep. I speculate that the underlying spoil will improve your drainage, and that if a bit of it gets among the clay top layer it could help by darkening the soil and encouraging it to warm up in spring. The only worry might be that there could be a high sulphur content in your spoil layer, but if things grow that won't matter a bit. If plants start looking funny, I'd suspect a mineral imbalance, but we can cross that bridge if we get to it. -- Mike. |

I'll continue with what I'm doing but I'll not dig down enough to reach the original mine shafts :O) You've made me feel a little more optimistic. Thanks, Keith |
