Hi

I'm digging a previously-shingled area of my garden for growing
vegetables and herbs. The ground doesn't look too bad; I'm not sure how
to describe the soil type but it doesn't appear to have significant
quanties of sand or clay.

Presumably I need to dig in some organic matter now. I have a large bag
of B&Q Organic compost; would that do? Alternatively, the local tip
sells bag of "soil conditioner" at a reasonable (I think) cost. How much
should I use, say per square metre?

Cheers,

Mark
