How to propagate osmanthus by cuttings? How to cut osmanthus

Propagation of osmanthus by cuttings should be carried out before germination in spring. The processing and cutting method and post-cutting management of cuttings are basically the same as those of monthly shoot cuttings. Because the cuttings of osmanthus are difficult to root, in order to promote its early rooting, it is best to soak the base of the cuttings in 400 500 ml of indoleacetic acid solution for 10 15 minutes before cutting, take it out, and insert it into plain sand or peat soil after the liquid is dried, keep it moist, and generally take root and survive after about 3 months.

The rooting effect is better if the base of the annual cuttings can be soaked in 50 ml of ABT rooting powder for 30 minutes. If you can't buy the above agents, you can also use homemade wicker extract for soaking.

Cuttings propagation osmanthus, choose the right season and choose the right branches, the survival rate is super high.

Select the robust and well-growing osmanthus tree periphery, the annual semi-lignified branches as cuttings, after pruning and disinfection treatment, cuttings in the fertile loose and well-drained sandy soil, placed in the position of astigmatism to keep warm and moisturize, ten days later, apply thin liquid fertilizer; It can take root in about a month, and the seedlings can be exposed to the sun but not to the sun.

Osmanthus cuttings are suitable for May 7 or 9 mid-October, these two months of osmanthus tree shoots no longer grow, nutrients gather in the branches, the climatic conditions are more suitable, the meristem organization ability is also strong, the cuttings are easy to survive, choose the right time is the most important step in the steps of how to cut osmanthus.

The cuttings used for cuttings should be cut on a healthy and well-growing osmanthus tree. Select the young branches on the periphery of the osmanthus tree, and the requirements are the branches that have been semi-lignified in the current year, and wrap the base with a wet paper towel after cutting to keep the water from being lost.

Prepare loose, fertile, well-drained acidic sandy soil, and carry out sterilization and disinfection in the sun, if it is a field cutting, the soil layer should be deep. Cut the cuttings obliquely 8 10 cm long, remove the leaves at the base, keep the upper 2 leaves, and soak the part of the lower end of the cuttings 3 cm long into the rooting solution for 1 hour.

First, use a wooden stick about the thickness of the cuttings to make a hole in the soil, and the hole is two-thirds of the length of the cutting; Then insert the cuttings into the holes, pay attention to the field cuttings to maintain the plant spacing and row spacing, compact the soil around the cuttings, and water and moisturize.

After cuttings, keep the soil moist and the humidity of the environment, put it in a ventilated and scattered position, and plant it in the field to build a shady shed; Ten days later, diluted potassium dihydrogen phosphate, superphosphate and urea are sprayed, and the roots can be taken about a month after additional fertilization. After the seedlings grow, they are slowly transplanted in the sun, but they should still be shaded in summer and not exposed to the sun.

Cuttings time, osmanthus cuttings can be carried out in spring and autumn every year, and cuttings need to be carried out in a sunny and windless afternoon; Soil is prepared, and when soil is prepared, humus, river sand, and pastoral soil can be mixed into a substrate for cultivation; The selection of branches should be carried out by selecting semi-lignified branches that grow vigorously and are not invaded by diseases. Cuttings method, when cuttings, the branches can be directly inserted into the soil, and the depth is controlled between 2 and 3 cm.

The cuttings of osmanthus can be carried out in spring and autumn every year, during which the growth of osmanthus is more vigorous, and the activity inside the branches is higher, and the survival rate after cuttings can also be greatly improved. And before cuttings, it is necessary to observe the change of climate, and it is necessary to choose a clear and windless afternoon.

Osmanthus is suitable for growing in loose and fertile, strong drainage soil, when cuttings, humus, river sandy soil, garden soil can be mixed into a cultivation substrate, after the preparation is completed, it is also necessary to spray the diluted carbendazim solution for disinfection treatment, so as to reduce the breeding of bacteria.

When cuttings are carried out on osmanthus trees, it is necessary to choose semi-lignified branches that grow robustly and do not invade by diseases, prune off all the leaves at the top and lower ends, and only retain the upper 2 3 leaves, and then disinfect the wound, and then place it in a cool environment to dry the water, and then take cuttings after the wound is completely dry.

When cuttings, the prepared branches can be directly inserted into the soil, the depth is controlled between 2 3 cm, so as to avoid affecting the normal respiration of the root system, after the cuttings are completed, they need to be placed in a semi-shaded and ventilated environment for maintenance, avoid strong light exposure, and ensure that the soil is in a slightly moist state, so that the branches can take root as soon as possible.
