It seems that whenever I buy herbs, particularly parsley and basil, they seem to go bad very quickly. I've tried putting them in a vase like flowers and keeping them out of the fridge but they go limp quickly and just lose it. I have tried cutting the roots off (on the basil) or leaving them on and it makes no difference. If I put them in the vegetable bin it's not much better if at all. How do you store your fresh herbs and how long do they stay?
