Does the baby's breath fertilize directly on the soil surface?
As a deeply loved ornamental flower, Gypsophila's leaves often cause yellowing due to improper fertilization during maintenance. Mastering scientific fertilization methods can not only promote the healthy growth of plants, but also effectively prevent the phenomenon of yellow leaves. This paper will analyze the two core issues in detail based on actual maintenance experience. Comprehensive analysis of the application of granular fertilizer nitrogen, phosphorus and potassium compound fertilizers are recommended to use layered fertilization method: first spread the fertilizer evenly on the surface of the soil and cover it with a thin soil buffer layer of 0.5-1cm. When watering, use immersion irrigation to allow water to slowly penetrate with nutrients, which not only avoids root burning but also improves utilization. The spring and summer growth season should be replenished every 20 days, and fertilization should be stopped during the winter dormant period. Specifications for the use of liquid fertilizers Liquid fertilizers such as Huabao must follow the principle of "applying thin fertilizer frequently" and alternate with watering after diluting at a ratio of 1:1500. The critical period of flower bud differentiation (4 weeks before bud appearance) can be increased to once a week, and the effect of spraying foliar fertilizer with phosphorus and potassium fertilizers is better. Pay attention to the need to strengthen ventilation after fertilization to prevent fertilizer solution from staying on the leaves and causing diseases. The comprehensive prevention and control plan for yellow leaves in the sky is urgent to deal with fertilizer damage. If yellow leaves on the whole plant occur, three-step emergency treatment should be taken immediately: ① flood irrigation for three consecutive days to dilute the soil fertilizer solution; ② remove 1/3 of the aging root system; ③ replace it with plain soil and put it in the pot. After treatment, place it in a cool place to slow seedling for 2 weeks, and gradually restore light after new leaves germinate. Physiological yellow leaf management The natural yellowing of old leaves at the bottom is a normal metabolic phenomenon. It is recommended to prune regularly every month to maintain an attractive plant type. When pruning, keep 0.5 cm of the base of the petiole and use scissors disinfected with alcohol. Simultaneous supplementation of chelated iron can enhance chlorophyll synthesis in leaves and prevent non-pathological yellow leaves. In addition to fertilization management, coordinated environmental control requires maintaining scattered light for 4 hours a day and maintaining a suitable temperature environment of 15-25℃. Combining measures such as ceramite pots and perlite soil (accounting for 30%) to improve the substrate can improve root stress resistance and reduce the probability of yellow leaves.
Through the combination of scientific fertilization and systematic maintenance, it can not only ensure the flourishing and luxuriant leaves of Gypsophila flowers, but also effectively prevent various yellow leaf problems. It is recommended to establish a maintenance log to record fertilization time, type and plant response, and gradually form a personalized maintenance plan.
