1. what fertilizer and what ratio of soil to compost
should I use?
2. should I add anything else? Sand?

Mike

Here's a mix that works for me:
3 parts sharp sand
6 parts garden soil ( I don't sterilize the soil - saves bother with
her indoors)
8 parts home-made compost

for seeds I don't add fertiliser but for potting-on I add some Fish
blood and bone (organic). Mix and sieve the ingredients very finely
for a good, moisture retaining compost.

Fromm a gardening book dated 1921:

half part fibrous loam (old turves are splendid)
quarter part leaf mould
eigth part well decayed manure.
sieve and remove any wireworms or other pests.

Hope this helps,
