PROBLEM WITH MY BASIL?
I grow my basil in the poly tunnel and for a few years I have had good success with a lovely y quantity that I use for my pasta cooking and especially for making my own pesto.
This year I don't know whats causing it, but I have had to discard so many of my basil leaves as they have a silver like colouring on the underside of the leaves.
Perhaps there is nothing wrong with this and the leaves can be used, but I have aired on the side of caution. Nevertheless, is there anybody on the forum who may know what causes this and/or where I maybe going wrong?
Your advice would be appreciated.
