In the cultivation of four seasons osmanthus, mainly Cuttage Propagation. The best rooting temperature of cutting propagation is 25 ℃ - 28 ℃. When cutting, if it is tender cutting, it is generally carried out from May to June. If it is hard cutting, it can be carried out from September to October. It should be noted that too high or too low temperature is harmful to the rooting of Sweet osmanthus. If the temperature is too high or too low, measures should be taken to save it. If the temperature is too high, the plastic film can be covered in time to increase the light appropriately. If the temperature is too low, it is necessary to shade and strengthen ventilation.
When cutting, the first thing is to choose soil. Generally, the soil is loose and fertile, with good drainage and sandy soil, which requires higher humus. Before cutting, the soil should be disinfected.
Next is the most important cuttings. Take down the appropriate cuttings in the morning and evening or in the overcast. The best cuttings are semi lignified branches, which can be cut into a section of 10cm. Keep 2 - 4 leaves on the top of cuttings, and stick some rooting powder on the bottom.
The treated cuttings can be inserted into the soil. After careful maintenance for a period of time, they can take root and survive.
When cutting, the soil humidity should be kept at about 50%, and the air humidity should be relatively high, above 85%.
In the early stage of cutting, the cuttings need to be shaded. The intensity of shading is 80%. With the growth of cuttings, the rooting begins, and then the light begins to increase.
In the cuttings grow about 10 days, you can spray it with a little potassium dihydrogen phosphate.
