What is this famous flower? How do you need to raise it

This flower is osmanthus. Maintenance method of Osmunda japonica:

1, soil:

Osmanthus fragrans has strong vitality, is easy to cultivate, has low requirements on soil, likes to grow in fertile and humid soil, and can also tolerate drought. It grows well in calcareous soil and acidic soil, grows well in slightly humid places, and grows best when planted in deep and fertile sandy loam.

2. Water:

Osmunda japonica is drought-tolerant and afraid of waterlogging. Water can be watered once a year before germination in spring and after defoliation in autumn. If it is not too dry at ordinary times, you don't need to water it. Generally, water 1 ~ 3 times in spring drought, and drain well in rainy season to prevent water from rotting. Autumn is not suitable for watering.

3. Sunshine:

Wei Zi bonsai likes light, so it usually grows in sunny and well-ventilated environment. In winter, you can spend the winter outdoors in the lee, while in the north, you should move indoors. Insufficient light will not only make plants spend less or not, but also make plants grow weak and have small branches and leaves. Therefore, it is necessary to place Osmunda japonica in a sunny place outdoors during the growing season.

4. Temperature:

Osmunda japonica is not cold-resistant and easy to freeze-dry. If it is serious, it will freeze to death. So move indoors in winter, and keep the room temperature above 7℃. When the temperature is lower than 7℃, methods such as plastic bag insulation, hot water heating and fire heating should be adopted. And pay attention to ventilation. When the indoor temperature is too high, you can open the doors and windows to reduce the amount of water, otherwise it will affect its normal dormancy and even root rot.

5, fertilization:

Osmanthus fragrans is a fertilizer-loving plant. Lack of fertilizer will lead to thin branches and yellow color, which will lead to weak growth of osmanthus fragrans, with few or no flowers, but excessive fertilization will lead to vain growth of branches and leaves. Fertilization can be carried out after the leaves of Osmunda japonica fall in winter and before germination in spring every year. It is best to apply human excrement or sesame sauce residue, which can make Osmunda japonica grow vigorously in the coming year and the flowers are large and bright.

6, pruning:

The crape myrtle inflorescence was planted at the top of the new branch of that year. Therefore, when pruning, the annual branches should be cut back again to concentrate nutrients and make the branches strong. Long branches, dead branches, drooping branches, pests and diseases branches, slender branches and endogenous branches should be cut off, and the lateral branches at the lower part of the trunk should be cut off in time during the young tree period, so that the upper part of the trunk can get enough nutrients and form a good crown.

7. Pests:

Lagerstroemia indica is prone to scale insects and sooty blotch under the conditions of insufficient light and poor ventilation. The scale insects can be sprayed with 40% dimethoate EC 1000 times solution or poisoned with 3% blown Dan granular soil. Aphids and pink aphids often occur in rainy season, which can be killed by spraying 40% dimethoate diluted to 1500 times or using 1000 ~ 1200 times 80% dichlorvos emulsion. Sooty blotch can be controlled by a mixture of stone and sulfur.

8. Replace the flowerpot:

Potted Osmunda japonica needs to be replaced every 2-3 years, and 5 parts of loose mountain soil, 3 parts of pastoral soil and 2 parts of fine river sand are mixed to make cultivated soil. When changing pots, organic fertilizers such as bone meal and bean cake powder can be used as base fertilizer and mixed in the surface layer of soil, so that the fertilizer can not directly contact the root system, so as not to burn the root system and affect plant growth.
