Tarmac Sharp Sand.
Hello looking for good advise. I grow my carrots in containers, I have been told to add Horticulture sharp sand 50/50 mix. Can I use ordinary tarmac sharp sand, or does it have to be Horticulture Sharp Sand.
kind regards
Nick

I'm assuming the sand you mention isn't the stuff for building though - ie making mortar or concrete?
Wisdom is not putting it in a fruit salad.
Useless for drainage though, as we've all said
Sharp sand is used for making concrete. Builders sand ( usually reddish colour ) is for mortar for brick layering / rendering etc no good for the garden its to fine of sand.
