What is the cheapest fertiliser to get hold of at the moment? We wouldn't

obviously we dont want it on a commercial scale. Thanks.

You're right it's 25Kg sacks. I've just phoned the local farm supplier and
the prices have gone up a bit, but well worth the investment:-
a) NPK 13:13:21 Ideal for root crops - £10.55p + vat
b) NPK 15:15:15 Ideal for surface crops - ditto price
c) NPK 18:12:20 Ideal for gardens and allotment - £14.99p + vat

Next year I may try c) it costs a bit more but the numbers are slightly
higher for N (Nitrogen) K (Phosphorus) K (Potassium). Here's a word of
caution about overdosing with Nitrogen:-

If in doubt, I trial with a half dose of 50g per watering can, at
fortnightly intervals.
