How to propagate osmanthus trees and precautions

Osmanthus tree reproduction method

The ways to propagate osmanthus trees include sowing, grafting, cut grafting, division, layering, and cuttings. Although it can also be propagated by seeds, the speed is relatively slow and not commonly used. The more commonly used method is cutting propagation, which has the fastest rooting.

Osmanthus fragrans breeding time

There are two periods a year when osmanthus trees can be propagated by cuttings, one is from May to July, and the other is from September to October. At this time, the new shoots stop growing and the branches contain a large amount of nutrients, so the survival rate of cuttings is high.

Osmanthus fragrans division propagation

The division propagation of sweet-scented osmanthus trees is generally carried out in October. 2-3 months before the division, first select an sweet-scented osmanthus tree with side hairs and root hairs from the cluster. Then it is necessary to half-cut it at the connection between the mother plant and the young plant. It is best to leave some mud balls attached to the roots of the young plant, and then it can be planted in the soil immediately.

Cutting propagation of osmanthus tree

For the propagation of osmanthus trees by cuttings, use new semi-lignified branches of the current year, which are conducive to rapid rooting. Cut them into 10-12 cm long, leave 2-3 leaves on the upper end, and cut the lower end into a horseshoe shape.

For the substrate for cuttings, do not use fertile media. It is best to use plain soil, such as pure sand, perlite, etc. Generally, the cuttings can take root in about 30 days.

Osmanthus fragrans seed propagation

The sowing time for osmanthus trees is in May. First, soak the seeds in warm water for 1 day, choose a land with loose, breathable and good water-repellent soil, turn the soil over, dry the soil, and spray the soil with a diluted insecticide solution of malathion. Then prepare a 10-cm-high seedbed with culture soil, and then sow the seeds.

Precautions for propagation of osmanthus trees

When breeding osmanthus trees, you need to choose a loose, breathable and fertile soil. For home breeding, you can buy some nutrient soil, add some sand, and then add some garden soil, and mix the soil in a ratio of 1:1:1.
