Once chives are about 12 inches tall, simply snip off what you need. You can cut chives down to about half their height without causing any harm. If your chive plant starts to flower, the flowers can be eaten as well!
Chives are an excellent source of calcium, iron, phosphorous, sulfur, potassium, vitamin A, and vitamin C. These vitamins help in blood count increase, maintaining blood pressure, and increasing immunity power. Additionally, chives contain choline and folate which are both linked to improving memory functions.
The culinary uses of chives are endless! Add chives to stocks, soups, salads, potato dishes, quiches, eggs, and even olive oils. However you choose to enjoy your home-grown chives, be sure to add them at the end of your meal preparation, as chives lose their flavor when heated.
