I grow basil in a pot indoors in the winter. I have a basil plant that I planted the first year I gardened in 2010. Dug it up and put it in a pot to bring inside.
I had fresh basil all winter, just kept harvesting it, and then took the pot outside in the spring kept repeating-it is still doing fine. I’ll be cutting it back any day now to bring indoors.
My girl up on her farm grows cinnamon basil galore and she dries a whole bunch to use in the winter. Sprinkle the dried flakes on eggs, fish ..etc.. and voila.....What a fantastic taste. I got some growing out back now so I’m hooked.
