Soil Amendment for New Plantings

15 years ago

Is there a general concensus as to the need for amending a planting hole in poor soils? I had always thought this to be a common practice until I stumbled upon some online information (including Linda Chalker-Scott's page of garden myths) that advocated zero amendments. Does this recommendation also apply to soils that are *not* native?

I would like to plant some carefree annuals around the neglected areas of my neighbourhood. The soil in the area is a heavy clay which I believe was trucked in during construction, so it contains a fair bit of concrete and other materials as well! I'm thinking twice about planting stuff in such "hostile" soil, no matter how hardy they are.

So, my question is: Should I amend with minimal organic matter, or simply mulch as much as possible?
