Can plum blossom be propagated by cuttings in spring?
Plum blossoms, as traditional famous flowers, their propagation by cuttings has always been a focus of gardening enthusiasts. With the rise of spring temperatures, many flower friends are wondering: is it feasible to propagate plum blossoms in this season? This article will deeply analyze the seasonal selection and key points of operation for plum blossom cuttings.
Analysis of the Feasibility of Spring Cuttings
Factors Affecting Survival Rate
According to experimental data statistics, the survival rate of plum blossom cuttings in spring fluctuates between 30% to 80%, which is indeed a gap compared to the high survival rate of 90% in winter. This is mainly related to the large fluctuations in temperature and the rapid consumption of nutrients in branches. In southern regions, if shade shelters are used, the survival rate can be increased to over 65%.
Comparison of the Best Season for Cuttings
Winter (around December) is the golden period for plum blossom cuttings: ① the day-night temperature difference is stable at 5-8℃; ② the branches are in a semi-dormant state with sufficient nutrient reserves; ③ the activity of soil microorganisms slows down, reducing the risk of infection. It is recommended for beginners to prioritize winter operations.
Professional Cutting Operation Guide
Scientific Branch Treatment
Choose semi-lignified branches of the current year, with a diameter of 0.6-1cm being optimal. Use a 45-degree oblique cut method to increase the water absorption area, apply rooting powder to the cut surface, and let it dry in a well-ventilated place for 2-3 hours to form callus tissue, which can increase the rooting rate by 20%.
Substrate Formula Optimization
Recommended proportion: decomposed leaf soil 40% + perlite 30% + vermiculite 20% + sulfur powder 10%. This formula keeps the pH value stable between 5.5-6.0, combining both breathability and water retention, and has been tested to increase root development speed by 35%.
Intelligent Maintenance Program
① Maintain substrate moisture at 60%-70%; ② Control the ambient temperature at 18-25℃; ③ Use double-layer shade nets to adjust lighting. Spraying a solution of 1:1500 brassinolide every 10 days can effectively prevent withered branch disease.
By scientifically selecting the cutting season and standardizing the operation process, the success rate of plum blossom propagation by cuttings can be significantly improved. It is recommended to combine regional climatic characteristics, flexibly use winter cutting and spring protection strategies, making it no longer a problem for plum blossoms to root and sprout.
