The Cultivation Method of crabapple Flower
As one of China's traditional famous flowers, crabapple flower is deeply loved by horticulture enthusiasts for its beautiful and elegant blooms. Mastering scientific cultivation methods can not only extend the blooming period but also cultivate healthy plants with lush branches and leaves. This article will systematically analyze the five core cultivation points from environmental control to daily management.
I. Water Management Techniques
1.1 Scientific Watering Schedule
crabapple flower prefers moist conditions but dislikes waterlogging. Keep the soil slightly moist in spring and autumn, and water immediately when the topsoil dries 1cm. Water thoroughly every 2-3 days during the high-temperature summer, and water once a week during the dormant winter period. It is recommended to use a long-spouted pot to water slowly along the edge of the pot to avoid rinsing the roots.
1.2 Rainy Season Protection Measures
Build a shelter during the plum rain season, and tilt the pot to help drainage during continuous rainy weather. Replace the breathable substrate immediately if waterlogging is found, and use a mix of pine needle soil and perlite (3:1) to improve the soil structure.
II. Light and Temperature Control
2.1 Light Intensity Management
Receive full sunlight in spring and autumn, shade 50% between 10:00-15:00 in summer, and ensure 6 hours of direct sunlight in winter. Place the pot on a south-facing windowsill indoors, and rotate the pot 180° every half month to maintain an even shape.
2.2 Overwintering Temperature Control
Keep the night temperature ≥8°C and the day temperature between 15-20°C. In northern regions, move the plant indoors before the frost season, use thick insulation film to cover the potting soil, and avoid direct cold wind on the plant.
III. Nutrient Supply Plan
3.1 Fertilization Schedule Planning
Apply decomposed soybean cake water every 20 days during the growing period (March-June, September-October), and increase the application of potassium dihydrogen phosphate (1:1000) during the budding period. Stop fertilizing in winter and switch to slow-release granular fertilizer during the high-temperature summer.
3.2 Foliar Fertilization Techniques
Apply chelated iron plus brassinolide (0.01% concentration) every month to effectively prevent yellow leaf disease and enhance the plant's resistance. Avoid operating during the high-temperature noon.
IV. Art of Pruning and Shaping
4.1 Basic Pruning Principles
Perform shaping pruning before the early spring germination, retain 3-5 main branches, and remove crossed and diseased branches. Pinch the top during the growing period to control height, and retain 8-12 functional leaves to promote bud differentiation.
4.2 Key Points of Pruning During Blooming Period
Remove the spent flowers immediately after blooming, leaving 2-3 plump buds. Perform a reduction pruning on the overgrown branches, and apply wound healing ointment to prevent pathogen invasion.
Through systematic cultivation management, crabapple flowers can bloom 2-3 times a year. It is recommended to establish a cultivation log to record watering and fertilizing times, bud differentiation, and adjust the cultivation plan dynamically based on the plant's growth status. Regularly apply carbendazim to the roots to prevent root rot disease, and maintain good ventilation to cultivate a colorful crabapple flower masterpiece.
