Hosta, also known as jade pen holder, is a perennial root herbaceous flower of the lily family. Its flower color is elegant, fragrant, and it is an excellent plant for garden flowers and potted plants. In traditional Chinese culture, hosta flowers are regarded as auspicious flowers, and are often used to make flower arrangements because of their fresh and elegant flowers.
1. Cultivation technology
1. Soil selection: Choose soil rich in organic matter, loose and breathable, and slightly acidic, which can be planted with a mixture of humus soil and garden soil. In addition, an appropriate amount of basal fertilizer should be added to enhance soil fertility.
2. Cultivation depth: Hosta is generally planted at a depth of 1/3 to 1/2 of its bulb, so that the root system can stretch naturally. The planting depth is about 5-7cm.
3. Light and temperature: Hosta likes a cool environment and avoids exposure to the sun. When cultivated indoors, it should be placed in a ventilated, semi-shaded place. The suitable growing temperature is 15-25°C, and the winter temperature is not less than 5°C.
4. Watering and fertilization: Hostas like moisture, but avoid stagnant water. The soil should be kept moist during the growing period, but not waterlogged. In terms of fertilization, it is sufficient to apply well-rotted organic fertilizer once a month during the growing season.
5. Pest control: The common diseases of hosta are root rot and brown spot, which can be sprayed with 600 times of 75% chlorothalonil wettable powder. Insect pests include aphids and needleworms, which can be controlled with targeted drugs.
II. Breeding method
1. Dividing propagation: Hosta ramification can be carried out before budding in spring. Dig out the mother plant and divide the bulbs for transplanting.
2. Seeding propagation: Seeding propagation is usually carried out in spring, and the seeds are soaked in warm water for germination treatment before sowing. The sowing soil should be kept moist to promote germination.
3. Tissue culture: Tissue culture is a fast and effective way to reproduce and can be done in the laboratory. By isolating the bulb or leaf tissue of hosta for culture, new hosta plants can be rapidly propagated.
3. Maintenance management
The maintenance and management of hosta mainly include watering, fertilization, pruning and pest control. During the growth process, maintenance measures should be adjusted in time according to the season and climate change to ensure the healthy growth of hosta.
In general, cultivating and propagating hostas requires a certain amount of patience and care. Through appropriate soil selection, depth control, light and temperature management, watering and fertilization, pest and disease control, as well as proper ramet, seeding and tissue culture methods, we can successfully cultivate healthy and strong hosta plants. At the same time, regular pruning and maintenance management are also important links to maintain the good growth of hostas.
