How to propagate osmanthus through cutting
A comprehensive guide to propagating osmanthus through cutting and the steps involved in growing green plants and flowers, let's find out together.
There are several methods for propagating osmanthus trees: grafting, seeding, layering, and cutting. Cutting is one of the more commonly used propagation methods. It is usually done between May to July and September to October, choosing fertile sandy loam soil, with the cuttings being young, partially lignified branches from the current year, and the cutting depth being 5 centimeters. Here is a detailed introduction.
1. Cutting Time
The best time for cutting osmanthus trees is between May to July and September to October. During these periods, the temperature is suitable. Osmanthus trees stop growing new shoots at this time, and the branches are rich in nutrients, which increases the survival rate of cuttings.
2. Soil Requirements
The soil used for cutting should be fertile sandy loam, as it is loose, breathable, and has good drainage. This type of soil is rich in nutrients and less likely to accumulate water, preventing the cutting from rotting due to waterlogging.
3. Cutting Treatment
Select a healthy branch from a vigorous mother plant that is free of disease. Cuttings are usually chosen from the upper part of the tree crown, preferably young, partially lignified branches from the current year. Cut about 10 centimeters, leaving 2 leaves at the top of the branch, cut the bottom of the cutting diagonally, and then soak it in a rooting hormone solution for about an hour.
4. Planting Cuttings
Before planting, make a hole in the soil with a small stick or bamboo skewer, then insert the cutting into the hole, about 5 centimeters deep. Then press the soil around the cutting and water the soil thoroughly with a diluted solution of carbendazim, cover with plastic film, and the cutting process is complete.
5. Maintenance
While waiting for the cuttings to root, keep the soil moist, spray twice with water daily to maintain the humidity around the cutting, and place the cutting in a cool, well-ventilated position. Once the cutting has rooted, it can be transplanted in the fall or the following spring.
