I was going to say the same thing as above
Grub -
I grow my own ...
My Polish Planter has lots of other herbs with it:
Note: Its not in direct sun -
moderate water (I let the rain do it for me ; only of its like a drought will I water it) ...
and picking it often ...
Picking herbs for me has produced
much more foliage and better tasting
younger herb leaves ~
