I bought some garlic the other day and a lot of the cloves were sprouting so I planted them in a pot. They are in a west window and are really growing. The green stem above ground is getting really tall. My question is can I cut this and use it to season food without hurting the bulb below ground? Or should I just let it continue to grow? I have only planted garlic in the garden once and it did not grow at all. Thanks.
