Several things.

I didn't mean to dis Cosmic; that is the brand I buy when I need to buy it. It is great, and I use the containers for the one I dry.

Second, I have regular mint - for ice tea and such - in a pot. I have been 3 years - yeah, YEARS -trying to get the rest of it out of the garden! With seven cats, I would need quite a few pots for the catnip. We also put some chicken wire around the base of some of it. With my cats and the neighborhood cats all partaking, they could potentially eat it right down the to roots and it would die off.

Edwina's Secretary: BEWARE. I had the paper towels catch fire on one batch last year in the microwave! I had been at it a long time, I was tired, I wasn't paying attention. Turn the microwave off, but don't open the door; that just gives the fire air to consume. With the door closed, it dies out fast. I tried, but the cats disapproved of that batch, and I had to throw it out. Charcoal taste, I guess.

I dry many of my herbs this way. Some take a little longer than others, depends how much moisture is in it. Basil, oregano, lemon balm, mint, parsley, and so forth.
