When to Repot plum blossom
As the leading flower among China's top ten famous flowers, the timing and method of repotting plum blossom directly affect the quality of blooming. Many gardening enthusiasts often cause damage to the plants due to improper operations. This article will systematically analyze the golden period and scientific operation process for repotting plum blossom.
Ⅰ. Choosing the Right Time for plum blossom Repotting
1.1 Advantages of Spring Repotting
3-5 months after flowering is the best repotting period, with a stable temperature of 15-20°C. The root recovery speed is twice as fast as in winter. The new root growth cycle can be completed in about 15 days, effectively avoiding the risk of dehydration caused by high summer temperatures.
1.2 Alternative Solution in Autumn
Repotting in September-October requires measures against cold, maintaining a nighttime temperature not lower than 10°C. Plants repotted at this time can increase the blooming quantity by 20% the following year, but caution is needed in northern regions.
Ⅱ. Practical Guide to plum blossom Repotting
2.1 Preparation Before Repotting
Stop fertilizing 7 days in advance and control water for 3 days to reduce soil moisture to 30%. Prepare a new container 5cm larger than the original one, with the number of ventilation holes increased by 50%.
2.2 Step-by-Step Operation Illustration
① Place the pot at a 45-degree angle and tap lightly to remove the pot, retaining 1/3 of the protective soil; ② When pruning decayed roots, keep at least 5 main roots; ③ Soak in a 1000-fold potassium permanganate solution for 20 minutes to sterilize.
2.3 Substrate Formula Optimization
Use a ratio of garden soil: decayed leaf soil: river sand = 4:3:3, adding 5g of bone meal per liter of soil. Keep the pH value between 6.0-6.5 and the EC value below 1.2mS/cm.
Ⅲ. Key Care After Repotting
During the seedling establishment period, maintain scattered light and keep the air humidity between 60%-70%. Start using a diluted 2000-fold root stimulant on the 10th day, and after 20 days, transition to normal care. The blooming quantity can increase by 30%-40% the following year, with a 25% increase in branch growth speed.
