How many years does it take for planted chestnuts to bear fruit?

Grafted chestnut trees begin to bear fruit in 2 to 3 years, while seedling chestnut trees bear fruit in 5 to 8 years, and after about 20 years the chestnut trees enter their peak fruiting period. Chestnuts have a cultivation history of at least more than 2,500 years in China. They are highly adaptable, widely distributed, easy to cultivate, and high-yielding, and can be economically cultivated on mountains, sandy beaches and other areas. They prefer sunlight, and can be cultivated in soil with a pH of 4.5 to 7.5, an average annual temperature above l0 degrees, an average growing-season temperature of 16 to 20 degrees, and a winter minimum temperature of minus 25 degrees.

How should fresh chestnuts be stored?

1. Refrigerated storage: There are two ways to store them under refrigeration. One is to not wash them and not remove the shells, wrap them well in plastic wrap or a plastic bag, and refrigerate them. The other is to sun-dry the fresh chestnuts for one day, remove the hard shells, then seal them with plastic wrap and refrigerate them. Generally, either way can store them for about one week.

2. Sand storage: For storing chestnuts in sand, generally spread a layer of sand on the bottom, then a layer of chestnuts, then another layer of sand, and repeat covering with sand and chestnuts. Then evenly spray an appropriate amount of water to maintain the moisture of the chestnuts, and they can be stored for a relatively long time.

3. Ventilated storage: Placing fresh chestnuts in a cool, ventilated place allows them to be stored for a relatively long time. In addition, fresh chestnuts can be soaked in cold water for 7 to 10 days, drained, then put in a bamboo basket or mesh bag and hung in a cool, ventilated place. Usually they can be stored for several months.
