Allotments 4 All

Hi All,
Found a sealed bag in the shed which came with some Sarpo spuds bought two seasons ago.
Don't need to use it for spuds, what other crop would benefit?

Why? Are you not growing Pots this year Tel?
???

Yes, but not so many Saddad, still have 2cwt. which won't get eaten as my OH & I don't eat so many and last years crop was very heavy.
