In what month will osmanthus blossom? Do you know any precautions for planting osmanthus trees?

Osmanthus fragrans is a common ornamental tree or shrub. The tree shape of osmanthus fragrans is not high, about 3-5 meters, with full crown and dense branchlets. Osmanthus fragrans is a widely used greening tree species at present. It likes warm and humid environment, cold-resistant and light-loving.

Prepare enough osmanthus seeds and use round seeds to ensure the survival rate. Osmanthus fragrans seeds are suitable for spring ploughing or autumn sowing. Adjust the land first, and put the umbilical cord horizontally when planting to prevent the radicle and young stem of the seed from bending. After planting, cover the surface with a layer of fine sand, then cover the grass felt tightly, pour water and water, and germinate in a few days.

The survival rate of osmanthus trees is relatively high when layering is carried out in spring or early summer. Select a relatively robust low-stem mother plant, select a robust branch of 1-2 years old, select a position that is very easy to bend, cut it to the phloem of the branch with a sharp knife, then press it into the soil layer 3-5cm deep to keep the soil layer moist until the branch takes root in autumn, and then cut it off and plant it.

Among them, Osmanthus fragrans, Osmanthus fragrans and Osmanthus fragrans generally bloom in September ~ 65438+10 every year, which is autumn. You can tell from the name that the four seasons osmanthus will bloom all year round. If properly maintained, it will bloom from February to March every year.

How to maintain the flowering period of osmanthus trees The flowering period of osmanthus trees is not long, generally only about 20 days. After flowering, osmanthus trees need to pay attention to reducing their sunshine time, so that they don't need to be exposed to the sun, otherwise the petals will wither early. Osmanthus fragrans cultivated in potted plants should be naturally ventilated in the shade after flowering, which can moderately extend the flowering period.

Osmanthus fragrans doesn't need to be watered too often during flowering to prevent the petals from falling off prematurely. Too much watering will also cause the branches to grow vigorously. When osmanthus trees bloom, spray water, just keep the soil layer moist, and the soil layer can't hold water. Osmanthus fragrans will stop fertilizing it during flowering, so it should be properly fertilized before flowering, and never be fattened after flowering. At this time, it will be reduced by supplementing it with nutrition.

Cutting of osmanthus trees should be carried out before germination in spring. Cuttings should be annual robust branches with a length of 5- 10cm. Cut off the leaves at the bottom and leave 2 or 3 leaves at the top. Special culture soil is used as the substrate for cutting cultivation. After cutting, the temperature is kept at 20-25℃, and it can take root in about two months. Spring and autumn are good times to plant osmanthus trees. If you want to choose in spring, you can do it in May and June. If you want to choose autumn, you can plant it in 65438+ 10. The natural environment and light source in autumn and spring are so beneficial to the growth and development of osmanthus trees, and the survival rate is high. If you want it to survive quickly, you'd better install some earth balls when planting it.
