How to cultivate bonsai Pinus elliottii

Bonsai cloud pine is a small plant decorated in the home, and many people like to raise it. Let's take a look at how to breed bonsai cloud pine and the breeding steps of bonsai cloud pine.

Culture steps

1. Using soil: the potted soil of Yunsong requires sandy soil with drainage, good ventilation and slightly acidic organic matter. Rotten leaf soil is commonly used to mix with yellow soil (or black mountain mud) and sandy soil, the ratio is 6:3:1. The basin soil should not be alkaline, otherwise it is disadvantageous to the growth, and the pine will yellowing and falling off.

2. Change the basin: when Yunsong goes into the basin, it is suitable to burn the mud basin, because of its good ventilation, it is easy to survive. Wait for the basin, and then change the form of simple, deep color purple sand pottery basin. The potted soil should be changed every 3-4 years, and the time of soil change should be from the end of February to the beginning of April or from September to mid-October. When changing the basin, cut off some old roots properly and water them thoroughly.

3. Watering: Yunsong is most afraid of waterlogging to hurt roots, so watering should be appropriate, not too much, foliar water should be sprayed frequently, soil moisture should be kept between 15% and 30%, and natural water is the best. It is generally irrigated once a day in spring and autumn, twice a day in summer and once a few days in winter. At the same time, it should be controlled flexibly according to the changes of the weather.

4. Fertilization: Yunsong should use thin fertilizer and less fertilizer, and fully mature cake fertilizer should be applied. Fertilization for mature plants should be carried out in spring and autumn. Spring fertilizer is applied every 10 days for 3 months before germination, with a concentration of about 15%, to promote germination and branch growth. The weather is hot from July to August, 10% dilute fertilizer and water should be applied once every half a month, and the application should be carried out in the morning and evening. September is the fastest stage of thickening and growth of Pinus yunnanensis, so autumn fertilizer can be thickened appropriately (the concentration of fertilizer can be increased to about 25%) to promote multiple axillary buds, fewer flower buds, and sufficient nutrients for stem and branch growth. IO should stop fertilizing after the end of the month. In addition, fertilization depends on the weather conditions. For example, it is not suitable to apply fertilizer immediately if it is sunny for a long time; if it is sunny for a long time, it should be watered first, and fertilize after 2 Mel for 3 days.

5. Lighting: Pinus yunnanensis is a strong positive plant, and the flowerpot should be kept in a dry, ventilated and sunny place. Too wet and too shady are disadvantageous to its growth. The seedlings of Pinus yunnanensis planted in potted plants of Agricultural Bank of China for 1-2 years should be placed in the outdoor open air at other times, except for proper shading to prevent the needles from being overexposed to the sun at noon in summer. In this way, the bonsai of Pinus yunnanensis has dense branches and leaves, thick green, high ornamental value and less diseases and insect pests. 6. prevention and control of diseases and insect pests. Cultivated Pinus yunnanensis, such as improper maintenance, is vulnerable to diseases and pests such as leaf blight, pine deciduous disease, pine tip borer, shell insects and so on. If leaf blight and pine leaf drop disease are found, the diseased leaves should be removed in time, and 50% methyl thiophanate wettable powder 800x solution should be sprayed. When pine tip borer, scale insects harm tip tips and feeding needles are found, 1000 times dichlorvos EC can be used to control them.
