Points to Consider When Repotting Duranta Plants
As a perennial succulent plant, Duranta is favored by gardening enthusiasts for its beautiful flowers and strong vitality. Repotting, as an important part of the plant's growth cycle, directly affects the plant's flowering performance and overall growth. Mastering scientific operational methods and understanding the law of seedling recovery can help maintain the vigorous vitality of your Duranta plants.
Core Elements of Repotting Operations
Choosing the Best Time for Repotting
2-3 weeks after the end of the blooming period is the golden operation period when the plant has finished consuming nutrients and entered the recovery phase. In southern regions, it is recommended to avoid the plum rain season, while in the north, it should be done after the spring equinox when the temperature is stable at above 15°C. For perennial old stakes, it is recommended to change the substrate every 2 years.
Optimal Substrate Mixing Ratio
The ideal ratio is humus soil: perlite: vermiculite = 5:3:2, with the addition of 5% bone meal to enhance nutrition. Heavy clay soil should be mixed with 30% coarse sand to improve aeration, and the pH value should be controlled between 6.0-6.5. The substrate should be sterilized at high temperature before repotting.
Standard Root Treatment Process
Use the pot-soaking method to soften the original soil ball, retaining 1/3 of the protective soil. When pruning, keep the fleshy roots with a diameter greater than 2mm, and apply charcoal powder to the cut ends to prevent infection. For a flower pot with a diameter of 15cm, it is recommended to keep 5-7 main roots to ensure a smooth nutrient transport channel.
Post-Repotting Care Management
Seedling Recovery Stage Environmental Control
Mature plants need to be cared for in a diffused light environment for 5-7 days, with the air humidity maintained at 60%-70%. Young seedlings with soil can be shortened to a 3-day transition period. Avoid the new cut ends when spraying the leaves with water in the morning and evening to prevent waterlogging and rot.
Water and Fertilizer Management Cycle
The扎根水 (rooting water) should be watered in two separate times, with a 2-hour interval to ensure water penetration. In the first month, apply diluted 1000 times the rapeseed hormone lactone, and supplement trace elements every 10 days. After the new leaves have unfolded, switch to regular maintenance and apply phosphorus and potassium fertilizers to promote bud differentiation.
Through scientific repotting and precise care, Duranta plants can quickly establish a new growth balance. Pay attention to observe the changes in the plant's condition, and adjust the maintenance strategy in a timely manner, which can shorten the root recovery period by more than 30%, laying a solid foundation for the plant to burst into bloom in the following period.
