How to sow the seeds of gardenia?

Seeding method of gardenia: Gardenia has high propagation coefficient, large number of seedlings and strong growth potential, which is the main breeding method in production. Sowing can be done in both spring and autumn, and spring sowing is better. Spring sowing is from late February to early March, and autumn sowing is from late September to 10. Before sowing, straighten the seedbed, apply human manure (1500 ~ 2000kg is 667m2) as base fertilizer, and then sow. The row spacing is 20 ~ 25cm, and shallow ditches with a depth of 2cm are opened. Then spread the seeds evenly in the ditch and cover them with fire ash or fine soil, with a thickness of about 1 ~ 2cm.

After a little pressing, cover the grass with 2-3 kilograms of seeds, and water the seedbed when seedlings emerge to keep the seedbed moist. After emergence, pay attention to the spacing between seedlings, keep the spacing between plants at 5-8cm, transplant the seedlings with spacing to another seedbed, and pay attention to shading, weeding and topdressing at seedling stage. One year after emergence, the seedlings can be planted with a height of more than 35 cm.
