Every year I grow a nice large basil plant. The problem is that the leaves are thick and tough. Is there a specific type of Basil that has the tender leaves or does the weather toughen them? Thanks. Pam

I have no information on what would cause a thickening of leaves. The plants do age and if the leaves are not harvested they can become larger and tougher.
Basil leaves are generally quite thin and though they can suffer from a few issues; this is not generally a sign of these diseases.
I'm listing some links that may help you.
