When the osmanthus tree is cut has a higher survival rate

Osmanthus trees can be cut at two times of the year, one from May to July and the other from September to October. At this time, the new shoots stop growing, and the branches contain a lot of nutrients, so it is easy to take root and survive after cuttings, and the temperature is more suitable for its growth. Cut 8-10 cm long shoots as cuttings, insert them into sandy soil to a depth of about two-thirds, press them tightly and water them thoroughly with diluted polybendazim solution.

Osmanthus is generally propagated by cuttings, and cuttings can be made between months and between months. It is best to use relatively fine, well-permeable soil as a bed.

Cut a branch from a plant that is growing well and has no insect infestation, about 8-10 cm. It is recommended to use the shoots that are new this year. Keep 2-3 leaves at the top of the shoot and cut off half of the leaves.

The position of the base is cut into an oblique mouth and soaked for 1 hour, the treated cuttings are inserted into the seedbed, and fine soil is buried around it, and watering can be done.

It is best around May or June, be sure to pay attention to fertilizing the osmanthus regularly, watering it every day, and moistening the soil for planting osmanthus flowers.

Generally, it is in the spring, probably in May and June, and if it is autumn, it is necessary to grasp the time in September or October.

Shoot selection and soaking: Select well-growing branches and soak them in rooting water. Soil sterilization:

Exposing the soil to the sun is effective in destroying bacteria. Correct cuttings: Poke a small hole in the surface of the soil with a wooden stick and put the cuttings in.

Conservation management: Keep the soil slightly moist and provide sufficient sunlight.

1. Select branches and soak them

Osmanthus tree cuttings time can be selected in May and June every year, at this time the internal activities of the plant are vigorous, the rooting speed is fast, select the branches that grow well before cuttings, cut off the leaves at the bottom, and at the same time cut the bottom obliquely to promote nutrient absorption, and then soak in the rooting water for 10 minutes and then take it out.

2. Prepare soil

Osmanthus tree cuttings should choose slightly acidic soil with good air permeability, which can be mixed with humus soil, garden soil and river sand, and then apply a small amount of decomposed organic fertilizer to improve soil fertility.

3. Correct cuttings

Poke a small hole in the soil surface of the osmanthus tree with a wooden stick, put the cuttings in, and then compact the soil, water thoroughly, if the temperature is low, you can cover a layer of plastic film after cuttings, as long as the cuttings are correct and the environment is suitable, you can grow roots in a month.

4. Maintenance management

Osmanthus trees like a moist environment, after cuttings are lived, once the soil is found to be dry, it is necessary to water in time, and the plastic film needs to be opened frequently for ventilation, and the fertilizer is applied every 20 days after the plant takes root, in addition, it is necessary to provide sufficient sunlight, but can not be exposed to the sun.

The propagation methods of osmanthus trees include "high-pressure method and cuttings method", and the survival rate is high if you master the skills.

1. Osmanthus is propagated by cuttings, and the time can be selected in spring, generally from May to June, and from September to October in autumn.

2. The slotting bed needs to be selected in the same breathable environment, and the substrate of the cuttings needs to be disinfected, and the substrate should be loose, breathable and fertile, and fine river sand can be used as the cutting substrate.

3. The temperature should be controlled in the process of cuttings, and the most suitable temperature for planning cuttings is 25 degrees, and the temperature that is too high and too low is not conducive to the rooting of the cuttings of the planning tree.

4. The cuttings should choose the peripheral branches that grow strongly, and it is best to choose the current year's born, semi-lignified, disease-free, robust branches, and cut about 15 cm.

5. The cutting method is very simple, first use scissors to prune the top of the branch into a flat mouth, and the bottom into an oblique edge, this is because the oblique mouth can increase the rooting area of the cuttings.

6. The top of the selected cuttings can retain 2 3 leaves, which can reduce the loss of nutrients, and it can be put into the diluted rooting solution for soaking before cuttings, and the time is one hour, and it can be taken out for cuttings.

The osmanthus tree should choose semi-lignified strong branches to make cuttings in order to survive.

This step is very important for the selection of cuttings, which is related to the survival rate of cuttings and the growth after survival in the later stage. We need to choose the slag of the eggplant tree with strong, semi-lignified branches for cuttings. Note that it must be a strong branch, if it is an old branch, a diseased and weak branch, it may affect the survival rate, especially after survival, the growth is poor, the vitality is weak, resulting in later management difficulties, and even dead seedlings and other adverse consequences.

Cut the cut branches into 10 to 15 cm segments, cut off all the lower leaves, leave two-thirds of the upper three layers of leaves, leave one-third, and cut the bottom into a beveled mouth. The length of the bevel is about twice the diameter of the branch.

Next steps

The quality of the substrate is also directly related to the success of cuttings. Loose and breathable planting material is usually selected as the substrate. For example, humus, cottonseed husk, river sand, wood flour, etc., pine bark powder can also be used, orchids, dendrobium, etc., pine bark powder has good air permeability, strong water absorption, and is an ideal substrate for cuttings.

To make a seedbed of cuttings in a small pot, you need to add a few tiles or pebbles to the bottom of the pot, gently insert the cuttings into the pine bark powder, insert half of it, leave half of it outside, and then press it hard. If the pine bark powder is not enough after compression, you can add some more on top and press it again. Finally, put a layer of moss in the mouth of the basin.

The purpose of putting moss is to moisturize, and at the same time, it can also play a role in suppressing the pine bark powder from being blown away by the wind.
