Garlic in a Nutshell

Garlic in a Nutshell

Garlic is a great food for your garden! Not only does it add flavor to your meals, but it can also improve soil and prevent pests. If you grow garlic in your garden, you’ll be able to eat fresh garlic all year long. Plant them in the fall when temperatures are cool (50 degrees Fahrenheit). One inch deep and four inches apart is the right way to plant. Water enough once a week until leaves appear about six weeks later. Harvest when tops turn brown by pulling the bulbs apart. Use pruning shears if needed.
