Adjust the temperature: The temperature range suitable for the growth of osmanthus trees is 15-28. Temperatures that are too high or too low can affect their growth. If the temperature is too high, it will cause the osmanthus tree to be burned by the scorching sun, and then the growth state is not good; If the temperature is too low, the plants will be damaged by frost and affect their growth. Therefore, it is necessary to take appropriate measures to maintain a suitable temperature range according to the season and weather changes.
Increase light: Osmanthus trees are light-loving plants and need sufficient light for photosynthesis to ensure normal growth. If the growing environment is too dark, growth will be stunted and new leaves will be difficult to germinate. Therefore, it is necessary to place the osmanthus tree in a sunny place and ensure that it receives at least 6 hours of direct sunlight every day. In summer, when the sun is strong, you can provide proper shade to avoid sun exposure.
Control water: When watering osmanthus trees, it is necessary to follow the principle of "seeing dry and wet", that is, dry and watered thoroughly, not dry and watered. Too much water can cause root rot and affect the growth of new leaves. Therefore, it is necessary to pay attention to the appropriate amount when watering to avoid stagnant water. At the same time, care should also be taken to avoid over-drying, so as not to affect the growth of the plant.
Fertilization: Osmanthus trees need adequate nutrients to support their growth. When fertilizing, it is necessary to follow the principle of "thin fertilizer and frequent application", that is, a small amount and many times to avoid the burden on the roots caused by too much fertilizer at one time. Organic fertilizers, such as well-rotted animal manure or plant residues, can be used in combination with watering. During the growing period, applying fertilizer every 2-3 months can promote the growth of new leaves.
Pest control: If the osmanthus tree is attacked by pests and diseases, it will also affect its growth. Common osmanthus tree pests and diseases include anthracnose, aphids, red spiders, etc. For the prevention and control of pests and diseases, it is necessary to focus on prevention, regularly check the growth of plants, and find and take corresponding prevention and control measures in time. Methods such as biological and chemical control can be used to control the spread of pests and diseases.
Pruning: Proper pruning can promote the growth of osmanthus trees. Pruning is mainly to remove weak branches, diseased branches and overly dense branches, so that the plant is ventilated and breathable, reducing nutrient consumption, which is conducive to the growth of new leaves. When pruning, choose the right tools and timing to avoid over-pruning and causing damage to the plant.
Soil change and soil improvement: Osmanthus trees are suitable for growing in loose, breathable, well-drained acidic soil. If the soil is compact, barren or alkaline, it can lead to stunted growth. Therefore, regular soil change or soil texture improvement can promote the growth of osmanthus trees. You can choose soil materials rich in organic matter, such as humus, peat, etc., and add an appropriate amount of acidic fertilizer to adjust the soil pH.
Reasonable propagation: The propagation methods of osmanthus trees include cuttings, grafting and sowing. Choosing the right propagation method can guarantee the health and growth of the plant. Cuttings and grafting are the most commonly used propagation methods, which can maintain the excellent traits of the female parent and are conducive to the growth of new leaves. Sowing propagation needs to pay attention to the quality of seeds and the growth environment to ensure the healthy growth of seedlings.
In short, to promote the growth of osmanthus trees, it is necessary to consider many factors. Attention should be paid to temperature, light, moisture, fertilizers, pest and disease control, pruning, soil replacement, soil improvement and propagation methods. Only in a suitable growth environment can the osmanthus tree grow healthily and germinate new leaves.
