Dunstan Chestnut Trees

Castanea dentata 'Dunstan'

Chestnut Trees have been a favorite of ours for many years but until recently, were vulnerable to fungus (blight). That all changed with the Hybrid American Chestnut; it is blight resistant and has truly been a blessing to everyone that loves chestnuts. Chestnut trees are easy to grow and care for and not only provide food for you but the local wildlife population will thank you for any leftover nuts your willing to leave. For the best nut production, be sure to buy two trees for superior pollination.

Dormancy Notice: This plant, like many others, enters dormancy or semi-dormancy in the late fall through early spring. *THIS PLANT IS NOT DEAD. It is completely healthy but upon receiving the plant, you may notice it exhibits fewer leaves, discoloration, or complete leaf drop. This is normal and essential to the plant's health. In fact, planting during dormancy promotes root growth, giving your plant a better start for spring, when new foliage will begin to grow.

Dunstan Chestnut Trees for Sale Online


Once beautiful and abundant, the American Chestnut Tree covered vast tracts of land across the eastern United States for thousands of years until a fungus (blight) from Asia decimated virtually every tree standing on North American soil. After nearly 70 years of absence, the American Chestnut is poised to make a comeback, thanks in part to the Dunstan Chestnut.

Dr. Robert T. Dunstan cross-pollinated American grafts with a mixture of USDA Chinese chestnut selections. The result is a blight-resistant Chestnut Tree. It is easy to grow and thrives in a wide variety of areas. Chestnuts are the very best tree for wildlife. Their consistent yearly crop of large, sweet nuts (unlike oaks and other nuts that cycle between heavy and light-years) provides regular, high-quality food for deer, turkey, squirrel, and bear.

The Dunstan Chestnut trees provide tasty chestnuts for eating raw or roasting. This blight-resistant tree is one of the most high-demand fruit/nut trees in the U.S. Although Dunstan Chestnut Trees will bear chestnuts 3 to 5 years after planting, it needs at least 2 trees to produce nuts.

About Your Dunstan Chestnut Trees

Growing Dunstan Chestnut Trees

The Dunstan Chestnut tree is a blight resistant, broad tree, with large leaves that turn yellow and brown during the autumn show. These trees are known for the plentiful production of chestnuts when two or more trees are planted within 200 feet of each other. It is recommended to buy these in pairs to build a beautiful chestnut grove.

These trees combine the excellent nut quality and tree form with guaranteed blight resistance. They have been grown successfully from Maine and New York, Illinois and Wisconsin, Texas and Florida. They are excellent for commercial and backyard orchards, and are the best tree to plant for attracting deer and wildlife

Soil Conditions & Light Exposure for the Dunstan Chestnut Tree

Dunstan Chestnut trees prefer well-drained, slightly acidic soil. A soil pH of 4.5 to 6.0 is best. Don’t fertilize Dunstan Chestnut Trees after August. Fall is the time for plants to begin preparing for dormancy. Fertilizing at this time may stimulate new growth that will be too tender to withstand the winter. In the south, a late May application and another in July would be about right. More northern areas may wish to fertilize only once in June or July. If you are looking for a fertilizing routine tailored to your specific conditions, a soil sample should be taken and the fertilizer and trace elements matched to the needs of your soil.

For optimal nut production, these trees should be planted in a place with full-sun exposure.

Uses for the Dunstan Chestnut Tree

This great American classic is most commonly used as a shade tree and for edible chestnuts it produces. Chestnuts are sweet and earthy, taste delicious and are very nutritious. They are packed full of amides, but also vitamin C (immune system boosting), folic acid, vitamin B (fights anemia), and minerals important for maintaining healthy skin, hair and muscles.

Nutritionally, chestnuts are like a "grain that grows on a tree" and similar to wheat and brown rice. Chestnuts contain up to 10% high quality protein, and no cholesterol. Low fat, high carbohydrate diets are recommended by the American Heart and Cancer Associations.

How to Care for Dunstan Chestnut Trees

Before you buy a Hybrid American Chestnut Trees, make sure to read about the care instructions that are required and recommended to keep this plant healthy and flourishing.

How do I plant my Dunstan Chestnut Tree?

How do I plant my Dunstan Chestnut Tree?

We suggest when planting your newly purchased Dunstan Chestnut Tree that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil, you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots of Chestnut Tree to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole.

How do I fertilize my Dunstan Chestnut Tree?

How do I fertilize my Dunstan Chestnut Tree?

Trees such as Dunstan Chestnut Trees grow best if they are fertilized lightly in the spring once frost has passed with a well-balanced, extended-release, fertilizer such as Espoma Tree-tone. Fertilize Chestnut Trees again 6 to 8 weeks later to encourage denser foliage or faster growth of young trees. Either chemical fertilizers or organic matter can be used successfully with Dunstan Chestnut Trees. Since an organic method of applying manure and/or compost around the roots, produces excellent results and also improves the condition of the soil, this would be an excellent first line of attack. Organic additions to the soil can also be combined with a shot of chemical fertilizer for maximum effect.

How often do I water my Chestnut Tree?

How often do I water my Chestnut Tree?

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Chestnut Tree a good deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example a one gallon pot would be watered until you count to 5 a three gallon pot would be 15 and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks.

What type of mulch do I use for a Chestnut Tree?

What type of mulch do I use for a Chestnut Tree?

We highly recommend that you mulch your Chestnut Tree with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away which will compete with your new investment for water and nutrients. A 2 to 3 inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch. Its better to leave a one inch gap of space between the mulch and the stem or trunk of the plant.


Additional Information

History of the American Chestnut Tree

Ever wonder what happened to the American Chestnut Tree? Once beautiful, majestic and abundant. For thousands of years, the American Chestnut tree thrived in our forests and covered huge tracts of land across the eastern United States. It was said a squirrel could climb a tree on the Atlantic coast and not touch ground until it reached the Mississippi River. The Chestnut was the dominant tree in America's eastern forests until an Asian blight wiped them out in the early 1900's. Until recently, you'd be hard pressed to find a single tree. Well, we're bringing 'em back. Introducing the Dunstan Chestnut Tree! After decades of crossbreeding, this blight resistant variety is here. Be a part of restoring this American tradition for years to come.
