Can sweet-scented osmanthus grow on the balcony?
Sweet-scented osmanthus is suitable for growing on the balcony.

Why don't sweet-scented osmanthus trees bloom?
1. Improper selection of seedlings: some varieties of sweet-scented osmanthus trees (such as purple cinnamon) can not blossom until they grow into trees, but it is difficult to blossom if they are mistakenly cut into seedlings. Osmanthus fragrans seedlings should be grafted with mature branches of improved varieties as scions, or obtained by high pressure method on flowering branches or even at the base, which is not only of good quality, but also easy to blossom after survival.
2. Improper cultivation: sweet-scented osmanthus tree likes sand soil is the most suitable, and it rarely blossoms in the soil with high alkalinity. If it is rooted or frozen when transplanting, it will weaken its growth and will not blossom in 3 to 5 years. Sweet-scented osmanthus trees prefer light to avoid temperature, long-term lack of light may not blossom. If the soil is too wet and rotten roots or long-term high temperature drying, it will also affect flower bud differentiation.
3. Fertilizer imbalance: sweet-scented osmanthus is a fertilizer-loving plant, but the more fertilizer, the better. Each plant has the proportion of fertilizer components that balance the domestic demand of elements such as nitrogen, phosphorus and potassium. If there is too much nitrogen fertilizer, the branches will flourish, but the branches and leaves will grow, but they will not blossom. Without leaves, yellow branches are thin, which affects the absorption of phosphorus and potassium fertilizer, and does not blossom.
4. disease: sweet-scented osmanthus trees are afraid of chlorine and are not resistant to oil fumes. If the lampblack is large, the growth is poor, the leaves become smaller and fall off, and cannot blossom. Sweet-scented osmanthus trees are also vulnerable to anthracnose, shell insects and other diseases and pests, not timely treatment, also affect flowering. In addition, mistakenly cutting spring shoots will affect the flowering of the same year. If there are too many branches of sweet-scented osmanthus in full bloom, it will weaken the growth and affect the later flowering.
How to cultivate potted sweet-scented osmanthus trees?
1, timely watering: sweet-scented osmanthus pot soil should grasp the principle of whether it is dry or irrigated, but spray fresh water to the leaves once a day. After the Qingming Festival, the sweet-scented osmanthus should be watered once in the open air, which should be watered in the morning and evening in summer and around noon in winter, so that the water temperature is close to the soil temperature, so as not to cause sudden cold and heat, and pay attention not to stagnant water.
2. Rational fertilization: sweet-scented osmanthus is mainly ornamental, and sufficient fertilizer should be provided. Nitrogen fertilizer can be applied twice during shoot sprouting, and phosphorus fertilizer is mainly applied before flower bud differentiation and flowering. The basin soil should be a little drier before fertilization, and it is appropriate to loosen the soil first so that the fertilizer can be absorbed, and water should be watered the next day.
3. Pour the basin and change the soil: the sweet-scented osmanthus should change the soil once every 2 ~ 3 years, cut off part of the old and withered roots, cover the bottom of the basin with a layer of river sand or vermiculite to facilitate ventilation and drainage, and place rotten cake fertilizer as the base fertilizer, the fill must be compacted. The ratio of soil to soil is not very strict, and it can usually be made of garden soil, barnyard manure and river sand.
4. Pruning and shaping: Osmanthus fragrans generally adopt the method of combination of climbing and pruning, which should be carried out after autumn. Plants with poor tree shape can cut off the whole top branch at 2 / 3 or 3 / 4, and plants with too dense branches should be thinned. After flowering, they should also cut off overgrown branches, withered branches, disease and insect branches, dense and thin branches.
5. Overwintering management: sweet-scented osmanthus overwintering room temperature should be kept at 0: 5 ℃ and relative humidity at 50: 80%. Winter cold indoor light should be good, especially before the early spring buds began to sprout, but also required sufficient sunshine, the following year Grain Rain arranged potted sweet-scented osmanthus to come out of the room. After leaving the room, first concentrate on the outdoor leeward to the sun, so that it gradually adapt to the external environment.
6. disease control: the common diseases of sweet-scented osmanthus are leaf spot, coal pollution, algae spot, root rot, iron deficiency and so on. Leaf spot, coal pollution and algal spot can be sprayed with 0.5 Bordeaux solution or 5% carbendazim 500-1000 times. Root rot should pay attention to keep the soil loose and permeable, do not accumulate water.
7. pest control: the common pests of sweet-scented osmanthus are leaf wasp, whitefly, mite, white scale, yellow moth and so on. Leaf wasps, whitefly and mites can be sprayed with 40% dimethoate 1500-3000 times liquid, and Changbai scale can be sprayed with 40% omethoate 1000 times solution or 40% fenitrothion 500 times solution in the first and second generation nymphs except manual brushing.
