1. Put the seeds of Toona sinensis into a cloth bag and gently rub them, and then remove the outer membrane of the seeds (or rub them directly by hand, which is easy to lose that membrane).

2. Wash and soak the seeds in clear water for 10- 15 hours in summer and 20-24 hours in winter. After soaking, wash and drain water, and then sow.

3. Put the towel, cotton cloth or paper towel on the seedling tray, wet it, and scatter the seeds evenly in the seedling tray.

4. Put it at 20-23℃ and avoid light to accelerate germination, and spray it with a watering can 1-2 times a day to let the air circulate.

5. When the new buds grow to about 2-3 meters, if there are rotten seeds, they should be removed in time. The temperature is around 25-30. Water 1-2 times a day, spray the seedling paper wet (keep it wet), and try not to accumulate water or drip water in the basin.

6. When the seedlings grow to 7-8 cm high, gradually increase the light.

7. When the leaves of Toona sinensis seedlings are green and flat, fully expanded, and the true leaves have not yet grown, they can be harvested and eaten at a height of 8- 10 cm!
