What should I pay attention to when changing plum blossoms
As the first of the most famous traditional flowers in China, changing plum blossoms is an important maintenance link to keep plants healthy. Correct pot changing operation can not only promote root development, but also improve plant disease resistance. This article will systematically analyze the six core points of plum blossom pot replacement from time control to pot filling skills, helping you easily master this key maintenance skill. The golden time for plum blossom pot changing selects the season and accurately controls the temperature. The best pot changing period is when the average daily temperature from March to April is around 15℃. At this time, the plant is in a semi-dormant state and the root system recovery ability is the strongest. If the winter temperature continues to be higher than 10℃, the operation can be advanced to late February. Optimize weather details and select windless cloudy days to avoid excessive transpiration caused by direct strong light on sunny days. In case of continuous sunny days, the pots can be replaced from 17:00 to 19:00 in the evening, and placed in a shaded place for maintenance immediately after completion. Three principles for selecting scientific proportions of flowerpots and soil containers. The diameter of the new pot should be 5-8cm larger than the original pot, and the veg-fired pottery pot is the first choice. Keep the old basin and soak it in 3% potassium permanganate for 30 minutes and then expose it to the sun for 48 hours to completely kill the pathogenic bacteria. The substrate formula is upgraded with a ratio of 5:3:2 (humus soil: coarse sand: bone meal), and 10g of slow-release fertilizer is added per liter of soil. Focus on ensuring that the EC value of the substrate is between 0.8 and 1.2mS/cm, and the pH value is controlled within the slightly acidic range of 6.0-6.5. Key technology for root treatment. Three days after the water was stopped, use bamboo strips to draw a 2cm gap along the basin wall. Keep the protective soil when removing 1/3 of the old soil, keep the white new roots when cutting off brown aging roots, and apply charcoal powder to the incision to prevent infection. The scientific operation specifications adopt the "three-filling and two-lifting" method: first, put 3cm of ceramite, put in the plant, then fill the soil to 1/3 of the place to gently lift the seedling, then fill it to 2/3 of the place to lift the seedling twice, and finally cover it with soil to leave a 2cm water outlet. Avoid watering within 24 hours after planting, and wait until root wounds heal before watering.
Through the above refined operations, the success rate of plum blossom pot replacement can reach more than 95%. After changing pots, the scattered light environment is maintained for 15 days, and combined with foliar spraying of 0.1% potassium dihydrogen phosphate solution, new roots can usually germinate in 7-10 days. Keep in mind the principle of "changing pots in three points and raising them in seven points" and regularly check the soil moisture, and your plum blossoms will surely grow vigorously.
