What should I do if the plum blossoms don't bloom?
Enjoy the fragrance of plum blossoms in the twelfth lunar month of winter, but what if the carefully maintained plum blossoms do not bloom? As a famous traditional flower in China, the maintenance of plum blossoms requires the mastery of key skills. From environmental control, nutrition management to pruning and maintenance, this article systematically analyzes the five core solutions to help you recreate the artistic conception of "thin shadows, horizontal slopes, clear water." 1. Optimization of light and ventilation environment 1.1 Insufficient light affects flowering. Plum blossoms are positive tree species and require ≥6 hours of direct light every day. Long-term shading will lead to long branches and hinder flower bud differentiation. The optimal growth temperature is 15-25℃, and winter requires a low-temperature vernalization process of 0-10℃. 1.2 Poor ventilation causes diseases and insect pests such as powdery mildew and aphids can be easily induced in a closed environment. It is recommended to maintain a 1.5-meter plant spacing and regularly clean up fallen leaves. Open windows for ventilation in spring and autumn, and can be used with circulating fans in summer. 2. Scientific pruning and flower promotion techniques 2.1 When the seedlings reach 20cm in the seedling period are finalized, pick the core for the first time, retaining 3-4 main branches. In the second year, the main branch was left with a 15-cm short section to cultivate the "three strands and six branches" skeleton structure. 2.2 Update and prune after flowering, retract the branches immediately after fading, retaining 2-3 bud points. Old pile trees need to be thin-cut and dense branches to maintain the crown light transmittance of about 40%. 3. Precise nutrition management plan 3.1 Basic fertilizer application key points When changing pots in spring, add decomposed cake fertilizer (50g per pot)+ bone meal (30g), and the pot soil is prepared at a ratio of 4:3:3 (garden soil + leaf soil + river sand). 3.2 The topdressing cycle is controlled by applying phosphorus and potassium fertilizer (0.2% potassium dihydrogen phosphate) during the flower bud differentiation period in June, stopping nitrogen and adding organic liquid fertilizer (diluted 500 times) in September, and stopping fertilizer in winter. 4. Intelligent water control strategy 4.1 Quantitative standard for watering "when it is dry and wet" in spring and autumn (watering when the soil moisture content is 20%), and watering once in the morning and evening in summer (single watering amount = 1/3 of the pot volume). 4.2 In the rainy season, emergency treatment of stagnant water for more than 2 hours requires immediate replacement of the basin. After pruning the rotten roots, soak it with carbendazim (1000 times liquid) for 30 minutes to replace the breathable pottery basin. 5. Additional measures for temperature control The northern region needs to enter the house for maintenance in winter and maintain a low temperature environment of-5 - 5 ℃. Flower buds can be wrapped with plastic wrap in the heating area to prevent premature germination. Jiangnan areas need to shelter from rain and freeze and build simple plastic sheds.
By systematically implementing five strategies of light regulation, scientific pruning, precise fertilization, intelligent water control and temperature management, and coordinating with the annual management rhythm of "changing pots in spring, promoting flowers in summer, storing energy in autumn, and dormancy in winter," plum blossoms can be effectively solved. problem. It is recommended to establish a maintenance log to record changes in phenological periods and gradually form a personalized maintenance plan.
