How to Grow Your Own Chestnut Trees

It’ss that time of year again. Jack Frost is nipping noses and chestnuts are roasting on open fires. Their smoky aroma drifts from streets vendors and fills living rooms. Party guests eagerly peel off the still-piping hot shells, revealing soft interiors packed with nutty flavor. Chestnuts are always a delicious winter treat, but smart gardeners know there’s no need to settle for the pre-packaged type. If you want to roast your own chestnuts by an open fire, you’ll just need to learn a thing or two about planting chestnut trees. Homegrown chestnuts won’t appear overnight. It usually takes about four seasons of tending to the trees before you’ll harvest your first batch of nuts. But it’s well worth the wait!


Where to Plant:
The American Chestnut is suited to USDA zones 4-8 and does well in warm climates, particularly where summers are hot. Plant your seeds in well-drained, moist ground. Acidic clay or loam soil is ideal. Look for an area that receives full sun or partial shade. Protect your trees from frost by planting on a hilltop or near a large body of water if possible.

How to Plant:
Spring is the best time of year to plant your chestnut seeds. If you want to produce nuts, plant several trees, as cross-pollination is necessary. You should leave about 20-25 feet between plants. This will give you a better chance at an abundant harvest once the trees start producing fruit! Plants seeds with their root shoots facing downward. If no root has appeared, place the seed with the flat side to the ground.

What to Expect:
You’ll see pretty white flowers form about 6-8 weeks after growth begins in the spring. By late summer chestnut burrs develop. These are prickly green capsules that usually cradle about three chestnuts. They’ll crack open when the chestnuts are ready for picking during the fall, dropping the fruit to the ground. Check for fallen, ripe nuts every other day during the fall to make sure you don’t lose any of your crop to hungry birds or squirrels! Remember, it takes several years for American Chestnut trees to bear their first nuts, so be patient! Eventually you’ll have a harvest of your very own chestnuts toasting on the hearth.
