Having a small garden with sandy/stony soil, I've decided to start from
scratch on a couple of raised beds by ditching the existing soil and
replacing it with something better. As this is a small project, I don't
care about the cost of materials but they need to be available from the
garden centre in 25kg bags.
Am I right in thinking that general purpose compost and sharp sand
should form the bulk? Things seem to grow well enough in that medium but
for how long? As a compost bin isn't practical for me, can I buy the
equivalent as a commercial product? Maybe a Phostrogen type liquid feed
would be as good?
Any advice appreciated
