According to Sogou Encyclopedia, generally speaking, the growth rate of chestnut seedlings in the first year is relatively slow, generally around 1-2 inches (about 2.5-5 cm). In the next few years, the growth rate will gradually accelerate until it reaches the height of adult trees. Chestnut trees can usually grow to 20-30 feet (about 6-9 meters) high, and some varieties can even grow to more than 40 feet (about 12 meters).

It should be noted that the growth speed and height of chestnut trees are not the only criteria, but the number of branches and the development of crown morphology are also important factors. Therefore, when planting chestnut seedlings, appropriate adjustments should be made according to the actual situation, such as pruning, watering and fertilization, so as to promote the healthy growth and development of seedlings.
