You can grow a lot of herbs and leaf lettuces in a 5 gallon container. I over-seed my containers when I just want to harvest leaves. Because you are not growing the plants to full size you can put in a lot of seeds, get a a lot of leaves, feed them and get more leaves.
The trick to getting more leaves until either the weather changes be it cold, frost or high heat... is to cut the leaves off and leave the roots in the ground. Most leaf herbs and leaf lettuces will quickly send up more leaves for you to harvest. This will go on until the weather changes.
Cilantro is a great herb to over-seed in a container. I also put in some arugula. I like the contrasting tastes in my salsa dishes. The video shows you how to harvest the leaves and talks about the points I mention in this entry. You can find this video at my new YouTube Channel for new gardeners: My First Vegetable Garden. I hope you check it out and subscribe.
