First of all, let me start off by saying that there is no perfect way to harvest garlic. However you can avoid common mistakes by following the guidelines in this video.
As you can see in the video above, using a garden fork instead of a spade, you can make sure you are not hurting the garlic bulb when harvesting. A good dose of potassium based fertilizer will help grow strong bulbs. Its also important to follow the instructions in the video for washing and curing garlic. It will help you keep your garlic store for a long time!
Have a great Labor Day Weekend and Happy Gardening!
