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 Dunstan 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.

Currently shipping fresh crop of Beautiful Trees


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 the blight-resistant Dunstan 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.

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. There has never been an instance of Dunstan Chestnuts dying from the blight. 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 American 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.

Directions for Roasting Chestnuts 

Chestnuts are excellent roasted or steamed (cut an "X" in the point of the nut so the shell splits easily) for 10-15 minutes. Chestnut dressing with turkey is a holiday tradition. They are wonderful in soups, stews, and with vegetables, or in desserts such as pastries, tortes and ice cream. Chestnut flour adds a rich, sweet flavor in cakes, breads, and pasta. Chestnut puree, blended with butter and whipping cream, can be spiced and used with main dishes, or sweetened with honey and topped with sweet whipped cream for the traditional European dessert, "Mont Blanc."

  • Large shade tree
  • Edible nuts (chestnuts)
  • Native source of food for local wildlife

Pruning Chestnut Trees

In general gardening terms, pruning is probably the most misunderstood gardening chore, and certainly, the chore that is most likely neglected. When we specifically look at pruning with regards to trees, this misunderstanding and negligence can be magnified. Pruning has been described as a “combination of art and science.” I find pruning to be one of the most relaxing yet rewarding chores in the garden. Pruning a specific plant to look a specific way, involves art in creating a unique definition for a specific plant, and it involves science in understanding the physical growing habits of the plant to be pruned.

The most important reason for pruning trees is to improve the overall health of the plant which in turn will reward you. Many times, trees that have not been pruned in a few years will develop dead or degenerative twigs. Removing the dead and dying limbs will minimize the possibility of diseases such as “dieback” and will also allow the plant to re-concentrate its energies and produce flowers.

It is important to always use sharp tools when pruning Chestnut Trees or any plant for that matter. Knives, hand cutters, saws, and shears should be sharpened if necessary before pruning any plant. A sharp cut will heal quicker than a jagged cut, which will also minimize the likelihood of disease investing a cut during pruning.  Its general purpose is to maintain or restore vigor to the plant.

Pruning large Dunstan Chestnut Trees that are well established will enable the plant to have continued vigor, and lead to many more years of supplying beauty to the landscape. Dunstan Chestnut Trees are the most common chestnut trees in America.

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 cultivar is here. Be a part of restoring this American tradition for years to come.


Planting Information

For the best results follow these guidelines.

STEP 1: PLANTING

STEP 1: PLANTING

We suggest when planting your newly purchased DunstanChestnut 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.

STEP 2: FERTILIZE

STEP 2: FERTILIZE

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.

STEP 3: WATER

STEP 3: WATER

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Dunstan 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.

STEP 4: MULCH

STEP 4: MULCH

We highly recommend that you mulch your Dunstan 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.
