How to maintain Bailian in winter
As a perennial flower, Bailia chinensis is favored by gardening enthusiasts for its elegant blue-purple inflorescences. However, improper maintenance in winter can easily lead to plant damage, and even no flowers to enjoy during the next year's flowering period. This article will systematically analyze the key points of wintering management of Pechia chinensis and provide solutions to flowering obstacles. Four core elements for winter maintenance of Pecilia chinensis 1. Light control strategy The full sunshine environment is the key to the winter of Phalia chinensis, and direct light needs to be guaranteed for more than 4 hours a day. It is recommended to place closed balconies on the south side in areas north of the Yangtze River, and open maintenance can be allowed in South China. Under special circumstances, a fill light is used to fill light for 2 hours a day to maintain photosynthesis efficiency. 2. Precise management of water and fertilizer uses the "three-finger detection method" to determine watering timing: insert your fingers into the soil 5 cm deep, and pour water through only when it is completely dry. Fertilizer application will be stopped from December to February of the following year, and slow-release phosphorus and potassium fertilizer (N-P-K=5-15-30) can be applied once in late November to enhance cold resistance. 3. Layered temperature protection establishes a three-level cold-proof system: when the temperature is 5 ° C, put a double-layer cold-proof cover, move it indoors at 0 ° C and lay a floor heating mat, and start the heating equipment at-5 ° C. It is recommended to use foam box nesting method for potted plants, and a 1.2-meter-high arch shed needs to be built for local planting. 4. Scientific pruning tips: Conduct sizing pruning 15 days before frost, keep the height of the main stem at 30cm, and cut 30% of the inner branches. Apply plant ash to the incision to prevent corrosion, and spray 50% carbendazim 800 times solution to prevent diseases after pruning. Causes and countermeasures for not flowering of Pucia chinensis When the plant does not bloom for two consecutive years, three main reasons need to be investigated: ① Insufficient light leads to obstruction of flower bud differentiation, and it is necessary to ensure that direct light for ≥6 hours every day during the growth period;② Lack of phosphorus and potassium elements, it is recommended to apply Huaduo No. 2 (diluted 1200 times) every half month from April to June;③ The root system is aging, and it needs to be renewed every 3 years, retaining healthy root blocks with more than 3 buds.
By implementing the "four-step overwintering" method combined with flowering control technology, the lily can bloom every year. Special reminder to northern flower lovers that they need to gradually increase the amount of watering after spring to avoid root damage caused by sudden temperature rises. Mastering these key technologies will definitely make your flower lily the most dazzling blue elf in the winter courtyard.
