When to Plant Potatoes and Garlic in New Hampshire

New Hampshire is known for cold winters. Even so, residents here can enjoy growing a number of herbs and vegetables. Potatoes and garlic are two crops that fare well in The Granite State.

Potatoes

• Plant potatoes when soil temperatures reach at least 45 degrees F. This is usually around the beginning of April in most of the state. Place cut pieces in the ground between 4 and 6 inches deep. Make sure the soil is dry and crumbles easily in your hands before covering the tubers.

Garlic

• Garlic should be planted in early to mid September in most of the state. Growing For Market recommends the soil be less than 50 degrees F at 9 a.m. before sowing. It should have time to develop strong roots before the ground completely freezes, so it should not be planted after a hard freeze.

Harvest

• You can dig potatoes any time after the plant has blossomed. Generally speaking, the longer you wait to harvest them, the larger they will be. Dig up plants completely around the end of September. Garlic can be harvested the spring after it is planted in the fall.
