How to raise chrysanthemums
As a famous traditional flower in China, chrysanthemums are favored by gardening enthusiasts for their diverse flower shapes and rich colors. However, many flower lovers often encounter problems such as thin plants and sparse flowers during the maintenance process. This article will systematically analyze the key points of chrysanthemum cultivation from six core dimensions to help you create a vibrant chrysanthemum landscape. Light and temperature regulation Sunshine demand Chrysanthemum is a typical positive plant and needs to receive scattered light for 6-8 hours a day. Full sunshine maintenance can be carried out in spring and autumn. In summer, a sunshade net is needed to filter 40% strong light from 10:00 to 15:00 to avoid leaf burns. In winter, a south-facing window sill should be placed to achieve uniform light reception by rotating the flowerpot. The optimal growth temperature band for temperature management is 15-25℃, and the temperature difference between day and night can be controlled at 8℃ to promote flower bud differentiation. When the temperature exceeds 30℃, ventilation needs to be strengthened. In winter, the overwintering temperature needs to be above 10℃. It is recommended to enter the house for maintenance in northern areas. The matrix and water and fertilizer control soil formula adopts a gold ratio of garden soil: leaf soil: perlite =4:3:3. Add 500g of bone meal and 2 kg of decomposed sheep manure to each cubic meter of matrix as base fertilizers. Reserve 1/3 of the soil when changing pots every year to ensure that the roots quickly adapt to the new environment. The watering rhythm grasps the principle of "seeing dry, seeing wet". Pour water thoroughly in 3-4 days in spring and autumn, once in the morning and evening in summer (avoid noon), and replenish water in 10-15 days in winter. The dipping basin method can avoid water accumulation in the leaf core, and it can be combined with ceramsite paving to enhance air permeability. Fertilization plan Apply nitrogen, phosphorus and potassium balanced fertilizer (20-20-20) every 15 days during the growth period, and use high-phosphorus potassium fertilizer (10-30-20) during the budding period, combined with spraying 0.1% potassium dihydrogen phosphate every week. Pay attention to applying thin fertilizer frequently, and return water the next day after fertilization. Plant and environmental management pruning and shaping were carried out three times at the seedling stage: the plant height of 15cm was picked for the first time, retaining 4 true leaves; the lateral branches were picked twice when they grew to 10cm; the pruning was stopped 45 days before flowering. Remove old leaves at the base in time to keep the plant ventilated and transparent. For pest and disease control, mancozeb is sprayed regularly to prevent leaf spot disease, and 2000 times of imidacloprid solution is used during aphid outbreaks. Setting up yellow sticky insect boards for physical prevention and control and maintaining environmental humidity at 60%-70% can effectively prevent red spiders.
By accurately controlling the four major elements of light, warm water, fertilizer, and scientific plant management, even novices can cultivate chrysanthemums with lush flowers. It is recommended to establish a maintenance log to record the time of each watering and fertilization and the plant's reaction, and gradually master the personalized maintenance rhythm. Change the pots in time when the root system fills the pots, and regular ramet reproduction can continue excellent strains.
