How long does it take grow a horse chestnut tree 25cm high?

A horse chestnut tree (Aesculus hippocastanum) typically grows at a rate of about 30 to 60 centimeters per year under optimal conditions. Therefore, reaching a height of 25 centimeters may take approximately 1 to 2 years, depending on factors like soil quality, sunlight, and water availability. However, growth rates can vary significantly based on environmental conditions and tree care.
