1. Seed selection: Before planting Toona sinensis, select good varieties according to their own conditions, and select varieties with large seeds, full grains and strong germination ability. Note that the germination rate of seeds stored for a long time will decrease, and it is best to harvest fresh seeds of that year.

2. Soak the seeds to accelerate germination: firstly, gently knead the collected Toona sinensis seeds, then prepare warm water, soak the seeds in warm water, take them out after cleaning, drain the water, and then put them into a clean container to accelerate germination. When the temperature is kept at about 25-30 degrees, it will germinate in about 2-3 days.

3. Sowing: When the seeds are mostly white, you can sow. Prepare the seedbed, dig a hole in the soil, sow the seeds of Toona sinensis in the hole, and then cover the seeds with soil.

4. Transplanting and planting: Toona sinensis is suitable for growing in fertile soil, and requires organic matter-rich, breathable, sparse and decomposed organic fertilizer to be applied to the soil in advance. Then transplant the Toona sinensis seedlings into the soil, keep the temperature at about 20-28 degrees, give enough light, water them in time and replenish water.

Second, what should I do if it is too high?

If the Toona sinensis tree grows too high, it should be topped, which can also promote the growth of branches and achieve the purpose of dwarfing.
