Things you need to know to keep your herbs and lettuce producing the best tasting leaves. One of the things to keep in mind is that you need to cut off the flowering tops as soon as you see them, so they don't go to seed. Stress can cause them to go to seed in a few week's so read up on your herb and lettuce and see if the sunlight is to much, and make sure there isn't over crowding in the area. Don't over water, every other day is okay, every day maybe a tiny bit but not to much you can drown them. Pick from the top and let the big guys do their job and catch some rays. Last but not least make sure you pick and harvest regularly this will keep the plant in production mode and it will keep producing leaves instead of flowers. Flowers are a plants way for dropping seeds to reproduce. If it drops the seeds the plant will start to die off, and there goes your fresh lettuce and herb supply. If you need to preserve the herbs you can find ways to do so here on Preserve Herbs.
