Is the goldenrain tree evergreen or deciduous? A detailed look at its growth habits
The goldenrain tree is also called wood goldenrain, goldenrain flower, and so on. It generally grows in calcium-based soil produced by the weathering of limestone, so is the goldenrain tree evergreen or deciduous?
1. Is the goldenrain tree evergreen or deciduous?
The goldenrain tree is a deciduous shrub or tree belonging to the Sapindaceae family and the genus Koelreuteria. Its main distribution areas in China are the Yellow River basin and the lower reaches of the Yangtze River basin. Its annual growth period is relatively short, and it is a relatively slow-growing plant.
2. Growth habits of the goldenrain tree
The goldenrain tree is a light-loving plant that tolerates partial shade slightly but does not tolerate waterlogging. When planting, pay attention to the soil. It is tolerant of drought and poor soil, has strong adaptability to the environment, likes to grow in calcareous soil, and tolerates salinity and short-term waterlogging. The goldenrain tree has a deep root system, strong sprouting ability, and a medium growth rate. Young trees grow relatively slowly, then gradually faster later, and it has a relatively strong resistance to smoke and dust. It is often planted in the Central Plains region, especially in Yanling, Xuchang.
The goldenrain tree has relatively strong wind resistance and can withstand low temperatures of minus 25°C. It also has relatively strong resistance to dust, sulfur dioxide, and ozone. It is mostly distributed in low mountains and plains below 1500 m in altitude, and can reach up to 2600 m in altitude.
3. Propagation methods of the goldenrain tree
1. Cutting propagation
After the trees shed their leaves in autumn, collect trunks with a basal diameter of 0.5-2 cm as cuttings, or collect the current-year sprout shoots or water sprouts from perennial goldenrain trees as cuttings, store them through winter, and take cuttings in the following spring.
2. Seed propagation
Select excellent individual trees that grow well, have straight trunks, open crowns, plump fruit, and are in their prime age as mother trees for seed collection. Collect the fruit promptly when it turns reddish brown or orange-yellow and the capsules have not yet split open, then pre-sprout the seeds and sow them.
