How to cultivate potted sweet-scented osmanthus trees Culture methods and matters needing attention

Osmanthus fragrans must be familiar to many people and can be seen in many places. It is a common and famous tree in our country. Sweet-scented osmanthus trees are now favored by many people at home with potted plants, which are highly ornamental. However, many people in the breeding process, due to technical problems, so there are a lot of problems, so it is very important to master aquaculture technology.

How to raise potted sweet-scented osmanthus trees

1. Light and temperature: the south of the Yellow River can overwinter in the open field. The north of the Yellow River needs to spend the winter indoors and keep it in a sunny place. The indoor temperature should be kept above 5 degrees, but not more than 10 degrees. The following April moved to the outdoor, first placed in the leeward to the sunny place to maintain, wait for stable growth, and then gradually moved to the ventilated sunny place. When the light is insufficient in the growing period, it affects the differentiation of flower buds.

2, basin soil: sweet-scented osmanthus does not have high requirements for soil. The basin soil can be mixed with humus soil or peat, garden soil, sand or river sand (proportion is 5:3:2). After production, the pH should be kept at 5.5-6.5, and the culture soil should be disinfected with 0.1% potassium permanganate solution before loading the pot.

Cultivation methods of potted sweet-scented osmanthus trees

1, watering: sweet-scented osmanthus watering should grasp the principle of not drying and watering thoroughly, and spray clear 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.

2. Fertilization: Osmanthus fragrans should be supplied with sufficient fertilizer, nitrogen fertilizer should be applied twice during shoot shooting, and phosphorus fertilizer should be applied mainly before flower bud differentiation and flowering. The basin soil should be a little drier before fertilization, and the soil should be loosened first, and should be watered once the next day of fertilization.

3. Pour the basin: sweet-scented osmanthus usually change the soil 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 base fertilizer, the fill must be compacted.

4. Overwintering: sweet-scented osmanthus overwintering room temperature is 0: 5 ℃, relative humidity is 50: 80%. The light in the cold room should be good in winter, especially before the early spring buds began to sprout. Grain Rain was arranged to go out of the room the next year, and first concentrated in the outdoor leeward and sunny place after leaving the room.

Points for attention of potted sweet-scented osmanthus trees

1. Potted sweet-scented osmanthus is not resistant to smoke and dust. if it is allowed to grow in a place with dirty air, it will lead to poor growth, smaller leaves and easy shedding, and little or no flowering, so it is necessary to prevent sweet-scented osmanthus from being polluted by smoke and dust during breeding.

2. Sweet-scented osmanthus is a long sunshine plant, which likes strong light. If the plant does not get enough light during its growth, it will cause its branches and leaves to grow too long, affect the formation of flower buds, and cause it can not blossom, so do not over-shade when breeding.

How to prune potted Osmanthus trees

1. Do not prune the whole plant. That is, slow release, suitable for the primary stage of sweet-scented osmanthus modeling in the young tree stage. It mainly includes twisting and twisting, the former is to soften the young branches in the early growth stage so as to change the growth direction and adjust the position. Pulling branches is for thick annual branches, by using iron wire and nailing wooden stakes to the ground to control the growth direction.

2. Small pruning. First of all, it is to pick the heart, remove the tender branches with 3 or 4 leaflets at the top of the branches, promote multi-branches, and are suitable for growing vegetative branches. Note that you must pinch the branches, but it will not work if you only pinch the leaves. Secondly, truncation is the work of growing branches in one year, after pruning, more than half of the branches are retained, which can promote the growth of buds in the upper part of the branches and promote multi-branches. Then re-pruning is to retain less than half of the annual branches. after pruning, the dormant buds in the lower part of the branches can be activated, which are likely to form new long branches or become flowering branches. The final retraction work is for a two-year-old long branch, cut off the growth part of the previous year, change the branch group, promote multi-branches, but also effectively control the part of flowering, no longer extension year by year.

3. Large pruning. This method is suitable for the renewal of old sweet osmanthus trees. After the first two kinds of pruning, it will not have a great impact on the whole tree shape, but a large amount of pruning is likely to change the original tree shape beyond recognition. It can also be used in combination with grafting.

Potted sweet-scented osmanthus trees must pay attention to temperature control when breeding, and protective measures should be taken when the temperature is low in the north. The amount of water is also different in different seasons. If you want sweet-scented osmanthus trees to grow well, timely pruning is also very important. There are some detailed introductions above. I hope it can be helpful to everyone.
