I have come by about 15kgs of fishmeal to use as fertilizer, Any suggestions on what to use it on & when?
Fishmeal is high in nitrogen and phosphate, so at a guess it would be good for anything which wouldn't actually need a high potash fertaliser - so not on your tomatoes and potatoes.
I'm not a big fan of fertalisers as the wrong one at the wrong time of year can do more harm than good, but I don't suppose it would hurt to give a light application to things in late spring - though certainly not this time of year as you don't want any rank growth going into winter.
Thanks for that, I've got it in a couple of plastic buckets ao it will keep, might rake a bit in the ground my brassicas are going in next year
