Paulownia is a plant of the Paulownia genus of the Scrophulariaceae family. It is also called white-flowered Paulownia, hollow Paulownia or large-fruited Paulownia. It is a common deciduous tree. The bark is gray-black, smooth when young, and becomes vertical when old. It likes plenty of light and a warm environment, and is not cold-tolerant. The origin is in my country, but it was introduced to Japan, Vietnam and other countries a long time ago, and is now distributed all over the world.

2. How to reproduce Paulownia

1. Sowing and raising seedlings: Sowing and raising seedlings are mostly carried out between February and March. Germination and disinfection must be carried out before sowing. The seeds can be soaked in warm water for about two days and then sown when the seeds are white, so that the germination rate will be higher. Pay attention to covering the upper layer of soil with a thin layer of soil after sowing to keep it warm and moisturized.

2. Buried root seedlings: every year after leaf fall to before germination To collect roots, select lateral roots that are two to three centimeters thick from a relatively strong growing tree, and control the length to 15-20 centimeters. Cut them and dry them in the sun for two or three days, and then bury them directly or diagonally.

3. Seedling cultivation by cuttings: In addition to the above two methods, seedlings can also be cultivated by cuttings. The specific method is to cut strong annual branches and make cuttings, with the length controlled to about 20 cm. After processing, just insert it directly into the matrix, and the survival rate is relatively high.
