Just had a delivery of seaweed extract. I wonder if it's worthwhile sprinkling some in with a few of the early spuds?? - aswell as manure or instead of? Too expensive to waste it but not tried it out before and would appreciate ideas on where best to use it. Have already put salt on the asparagus as a trial - I wonder if it's the salt on the seaweed they like or the combination of salt and nutrients?
