Are there any true American chestnut trees left?
However, because the blight fungus does not kill the root system of trees, American chestnuts persist today in natural areas as re-sprouts from blight-free root systems. One of those areas is Rock Creek Park. The American chestnut was once a dominant tree of the eastern U. S. While it was nearly wiped out by disease, survivors still exist today in Rock Creek Park.American Chestnut Native Range The American chestnut tree reigned over 200 million acres of eastern woodlands from Maine to Mississippi until succumbing to an imported fungus known as the chestnut blight during the first half of the 20th century. An estimated four billion American chestnuts grew within this range.The Tree’s History This Great Hybrid American Chestnut tree is resistant to the blight, fast growing, and can begin producing chestnuts at 3 to 5 years of age. The Blight (chestnut bark disease) is a fungal disease on chestnuts that eliminated mature American chestnuts in 1904, stemming from Asia.American Chestnut Restoration and Conservation The American Chestnut Foundation (TACF) is leading an unprecedented mission to restore the American chestnut tree to its native range. The iconic American chestnut was devastated by chestnut blight in the early 1900’s.Chestnuts have been a food source for thousands of years. They can be eaten raw, roasted, ground into flour or mixed into baked goods. They grow on trees in the genus Castanea, and many species in this group can live to an impressive 500 years or more.
What is special about chestnut trees?
Chestnuts are dense with calories, rich in vitamin C and antioxidants, and the leaves contain higher levels of essential plant nutrients than other local tree species. This made the chestnut beneficial not only for the humans of an ecosystem, but for every level of the food chain. Raw chestnuts are safe to eat for most people. However, they do contain tannic acid, which means they could cause stomach irritation, nausea, or liver damage if you have liver disease or experience a lot of kidney problems.Chestnuts contain less saturated fat than walnuts. Chestnuts are rich in vitamin C, which boosts immunity. They are high in potassium, which helps to lower blood pressure.

This toxin is found in the leaves, flowers and twigs of the Horse-Chestnut.
How long does it take to grow a chestnut tree?
Chestnuts can be a very profitable crop. They begin to bear in only 3-5 years, and by 10 years can produce as much as 10-20 lbs/tree. At maturity (15-20 years) they can produce as much as 50-100 lbs/tree or up to 2,000-3,000 lbs/acre each year. Powerful and majestic, the chestnut can live for a long time (up to 1,500 years) and reach up to 30 meters in height. It is prized for its wood and its nuts.Chestnuts are deciduous trees with alternate, short-stemmed, prominently veined, oblong leaves that have course to fine pointed marginal teeth or bristles.Chestnut trees vary in size from the very large American species that grow over 80′ tall, to the mid-range European cultivars that reach around 65′ in height, and the smaller Chinese species that top out around 40′ at maturity.Chestnut trees have deep roots so a tall container is optimum. A one or two quart milk container with the bottom removed will work.
Which country has the most chestnut trees?
China and Korea are the largest producers of chestnuts in the world. The Chinese chestnut has a flavorful nut and is resistant to chestnut blight. Korea grows Chinese-Japanese cultivars. Chestnuts are dense with calories, rich in vitamin C and antioxidants, and the leaves contain higher levels of essential plant nutrients than other local tree species. This made the chestnut beneficial not only for the humans of an ecosystem, but for every level of the food chain.Chestnuts were a high carbohydrate food source for thousands of years. Its beautiful and rot-resistant wood is used in everything from vineyard stakes and fence posts to siding and bridge timbers and was a major source for tannins used in the leather industry.In Korea, we use chestnuts in many tasty ways.

The Chinese chestnut has a flavorful nut and is resistant to chestnut blight. Korea grows Chinese-Japanese cultivars. Japan is also a major consumer of chestnuts. Japanese nuts are large, but do not have nearly as good a flavor as Chinese nuts.Reproductive Life-Cycle of the American Chestnut Therefore at least two chestnut trees need to be near each other for viable nut production. Female chestnut flowers develop into burs that contain up to three nuts at maturity. The nuts are ready for harvest when the burs begin to open up.Chestnut trees flower in early summer and produce either only male flowers or both male and female flowers, but rarely self-pollinate.
