When is the best time to change the pot?
As a representative of perennial evergreen herbs, Clivia is loved by flower friends for its straight leaves and elegant flower posture. However, many people often cause plant growth to be hindered due to improper pot replacement, even root rot and other problems in the maintenance process. Mastering the correct time and operating skills for changing pots is the key to keeping Clivia vigorous vitality. 1. Analysis of the best time to change pots for clivia 1. According to long-term observation by horticultural experts, when the temperature stabilizes in the range of 15-25℃, it is most suitable for pot changing operations. The specific time should be from March to April or September to October in the northern region, while the southern region can be advanced or postponed by 15 days. At this time, the plant is in an active growth period, and the root system recovery rate after changing pots can be more than three times that of winter. 2. Criteria for special circumstances When it is found that white fleshy roots protrude from the drainage holes in the bottom of the basin, the soil is severely hardened, or the leaf color is yellow and growth is stagnant, the pot needs to be replaced immediately even before spring and autumn. It is recommended to combine a fixed frequency of pot changes 1-2 times a year to effectively avoid nutrient depletion. 2. Detailed explanation of the whole process of changing pots of Clivia 1. Before changing pots, the key preparation is to stop watering 5-7 days in advance to make the soil semi-dry. Select a purple sand pot or pottery pot with a diameter 6cm larger than the root diameter. To prepare disinfected sharp scissors, carbendazim solution needs to be prepared and used at a ratio of 1:800. 2. Core techniques for removing pots and pruning roots gently tap the wall of the pot to loosen the soil, remove the soil ball completely and retain 1/3 of the core soil. When pruning, keep the main root length of about 15cm, and thoroughly remove the black rotten roots and empty withered roots. After pruning, it needs to be dried for 2 hours to form a protective layer, which can reduce the risk of bacterial infection by more than 50%. 3. The recommended formula for scientific soil blending plan is: 40% humus soil +20% pine needle soil +15% volcanic rock +10% charcoal +15% river sand. This structure not only ensures air permeability, but also maintains a slightly acidic environment with a pH value of 6.0-6.5. The measured water holding time is 2 days longer than that of ordinary garden soil. 4. The operating points of basin upper use the "three-layer filling method": 3cm of ceramite is laid on the bottom layer, 5cm of mixed soil is placed on the middle layer, and the upper layer is covered with nutritious soil. Keep the false bulbs 2 cm higher than the edge of the pot during planting. After filling the soil, gently lift the plant to stretch the root system naturally. It is recommended to use the dipping basin method for the first time to pour root-fixing water and last for 15 minutes. 3. After the critical period of maintenance after changing the pot, it is necessary to place it in a scattered light place to slow down the seedlings for 7-10 days, and maintain the environmental humidity of 60%-70%. The interval between the first three watering times will be extended to 1.5 times of the original cycle, and nutrient solution diluted by 2000 times can be applied after new leaves have germinated. Through scientific management, the survival rate of Clivia after changing pots can reach more than 95%.
