Planting – Chestnuts have a propensity to rot in compacted soils, therefore a growth medium with abundance of fiber materials is a suitable choice. Soil-less potting mixes with plenty of decomposed bark is a nice alternative. These mixtures give plenty of aeration and assist protect the root ball when it comes time to transfer the seedlings.
The nuts should be planted 0.5 to 1 inch deep with the flat side facing downward. Make sure to keep the soil moist, not soggy and sometimes sprinkle a weak solution of complete fertilizer. The seedlings should be ready to transplant mid-May following the last serious frost. Prior to transplantation, seedlings should be “hardened off.” Place them outside and gradually expose them to the sun and sharp breezes to accomplish this.
When planting the seedlings, create the hole twice as large as the root ball. Be sure to remove the remaining nut shell from the root. This helps prevent animals from pulling up the seedlings to get to the nuts. Like blueberries and azaleas, chestnut trees like well drained, acid soils.

Can a chestnut tree be grown from a chestnut?
Quick Growing Guide – The American Chestnut Foundation American chestnut seedlings are highly varied in their hardiness and vegetative health. Choose a source of seeds from a climate that is as comparable as feasible to that of your region in terms of minimum and maximum temperatures, latitude, and altitude.
If there is a warm time in the middle of winter, many hybrids and pure Chinese trees may lose their cold resilience and be injured when the cold weather returns. If you are harvesting your own seed, be mindful that isolated, unpollinated chestnut trees will produce burs anyhow, with small, flat, shriveled nuts inside-these are not viable.
Because chestnuts are incompatible, many trees are required to yield viable nuts. Most experienced farmers prefer planting their nuts in the spring, as sowing in the fall might result in substantial or even total rat losses. Fall-harvested nuts must be kept in cold storage for several months before they can be sown in the spring.
The storage conditions for chestnut seed are stringent; it must not dry out or get mushy, nor may it freeze or be kept for an extended period of time over 40 degrees Fahrenheit. Sand, sawdust, peat moss, unmilled sphagnum, vermiculite, and plastic bags with holes have all been utilized successfully to preserve chestnuts.
The storage medium must have some capacity to hold moisture but must also be able to drain, as the nuts “exhale” quite a quantity of water during storage and can get overly wet in a wholly closed container. The acidic quality of sphagnum or fresh sawdust is beneficial for inhibiting the development of rotting fungus.
If using a neutral medium such as vermiculite, wash the nuts in a Clorox solution (one part bleach to nine parts water) and then rinse them in sterile water (boiled water that has been allowed to cool). If storing items outside, the container must be rodent-proof. A substitute is the refrigerator. In a jar, layer the nuts and the moist (not wet) storage media, and loosely cover (with a Saran wrap-like material).
Check the jar once a month, and if any green growth is obvious, repeat the Clorox cleaning as mentioned above. It is typical for stored nuts to begin sprouting (usually between late February and late March). If the roots become much longer than 1 inch, they are challenging to plant.
Are chestnuts simple to raise?
American chestnuts are hardy, productive trees that reward their cultivators with several feet of annual growth. They can survive and even flourish in a variety of environments, but there are a few that can result in trees that are sickly and develop slowly.
