When the pot should be added decomposed organic fertilizer such as bone meal as a base fertilizer.

2. Selection of flowerpot: When potted osmanthus flowers, it is recommended to plant them in earthen pots with good ventilation. Bottom fans follow tiles to facilitate drainage.

3. Potting time: The planting time of osmanthus fragrans should be selected in late autumn from November to early December, or in spring from February to early March. The seedlings should be potted in spring as much as possible to avoid freezing damage in winter. After the basin should be poured through water, placed in a ventilated place to slow seedlings, 1 week later moved to a sunny place maintenance.

4, water management: potted osmanthus should keep the pot soil moist, rain season should pay attention to drainage, in case of more water and rotten roots. Autumn flowering, should avoid pot soil too wet, otherwise easy to appear flower, bud drop phenomenon.

5, fertilization: spring germination should be 10-15 days to apply a 30@cake fertilizer water, after July in the application of cake fertilizer water at the same time add potassium dihydrogen phosphate or calcium superphosphate, to promote flower bud differentiation.

6, pruning: autumn flowers after pruning, will be dead branches, thin only he, pest branches cut off, so that each side branch evenly left thick short branches. And in the growth period should be sprouting branches cut off in time to avoid excessive consumption of nutrients.

7, pest control: osmanthus easy to get carbon maggot disease, brown spot disease, coal pollution disease, whitefly scale insects and leafhoppers, etc. Attention should be paid to timely prevention and control.

II. Four taboos in the process of osmanthus cultivation

1, avoid alkaline earth: osmanthus love slightly acidic soil, pH 5.5-6.5 is appropriate. If planted in alkaline soil, it can cause the leaves to wither or even the whole plant to die.

2, avoid watering half water: watering is not transparent, the soil surface is wet, the lower half is dry, the root system does not get enough water, resulting in dry leaves, and even leaves falling off.

3, avoid water: water in the soil is easy to cause rotten roots, leaves, a long time, the root system will rot, leading to plant death. Pay attention to drainage in rainy season.

4, avoid high temperature winter: osmanthus is relatively cold, south of the Yangtze River can winter in the open field, North China area indoor winter, room temperature to 2~4℃ is appropriate. If the room temperature is too high, dormant buds sprout in winter or early spring, deplete nutrients, and the plant will develop poorly. Early spring drought in the north is windy, potted osmanthus flowers should not be out of the room too early, otherwise the new branches will be damaged by strong wind; osmanthus flowers are also afraid of smoke, not planted near factories and mines.

III. Common problems of osmanthus cultivation species:

1, potted osmanthus flowers less, fragrance is not thick what is going on?

This number is caused by insufficient nutrition or insufficient light, osmanthus love fertilizer, in addition to base fertilizer, growth period and before flowering, flowering should be timely topdressing; osmanthus love sunshine, light should be sufficient, should be planted in sunny and well-ventilated places and timely pruning.

2. What should I do if potted osmanthus flowers are not easy to bloom?

Potted osmanthus seedlings about 8-10 years to flower, cutting seedlings need about 4 years, ramets and grafted seedlings can mostly flower in the next year, if potted osmanthus has reached the flowering age does not bloom, it is mainly due to improper maintenance reasons. Such as improper watering, ponding, alkaline soil, overwintering temperature, smoke damage, insufficient light, etc. will cause osmanthus flowers do not bloom. In addition, potted osmanthus flowers often do not change soil, insufficient fertilization will also affect the flowering of plants.

3. How can osmanthus blossom every year?

If you want osmanthus flowers to bloom every year, maintenance is very important, first of all to ensure sufficient light, secondly to pay attention to fertilization, as the saying goes: to want osmanthus fragrance, prepare pig manure tank. It can be seen that osmanthus is very fond of fat. Base fertilizer should be applied in winter, nitrogen fertilizer should be applied mainly in growth period, phosphorus and potassium fertilizer should be applied in flower bud differentiation period.

4. How to prevent osmanthus from falling seriously in winter?

In cold areas, potted osmanthus flowers should be moved to a place with sufficient indoor light in winter to avoid falling leaves due to freezing damage. After flowering in autumn should be applied thin nitrogen fertilizer, winter before the application of base fertilizer, winter should be covered with sand, irrigation with water.

5. Why is the tip of osmanthus leaf scorched?

Osmanthus leaf tip scorched should first eliminate disease, if osmanthus got charcoal maggot disease and other diseases will show leaf tip scorched, usually should strengthen ventilation, watering not too much, dead leaves should be cleaned up in time, found sick leaves should be cut off and burned in time.

When the basin soil alkalization, also will appear leaf tip scorched phenomenon, osmanthus flowers are fond of acid, should pay attention to keep the soil acidic.

If winter enters the house too early, or overwintering temperature is too high, lead to bud germination early, move to the outdoor in spring, after drought, wind blowing also easy to appear withered phenomenon.

Osmanthus has a wide variety of varieties, evergreen flowers and beautiful flowers, is a very suitable street and courtyard planting green seedlings, so love flowers friends hurry to see the above osmanthus cultivation methods and precautions!
