How to Repot a Dragon Flower
As a representative species of the Agave family of succulents, the Dragon Flower is favored by gardening enthusiasts for its unique sword-shaped leaves and robust vitality. Regular repotting not only improves the root growth environment but is also a key measure to prevent diseases and pests. This article will systematically analyze the five core stages of repotting a Dragon Flower, helping you create a healthier ornamental potted plant.
Preparation Points Before Repotting
Golden Rule for Potting Soil Ratio
The Dragon Flower's fleshy roots require strict drainage, so it is recommended to use the golden ratio of "nutritious soil: decomposed leaf soil: coarse sand = 3:2:5". To enhance water retention, 200g of vermiculite powder can be added to each cubic meter of substrate, and 50g of bone meal can be mixed in to supplement calcium, effectively preventing leaf tip browning.
Three Elements for Choosing a Pot
The new pot diameter should be 5-8cm larger than the original pot, preferably choosing breathable materials like red clay or purple sand pots. The pot bottom must have three or more drainage holes, and it is recommended to use broken tiles to create a drainage layer, which can reduce the risk of root rot due to积水 by 30%.
Scientific Repotting Operation Process
Technique for Handling Roots When Removing from Pot
Water control is needed 5-7 days before repotting to allow the soil to contract, using the "upside-down rotation method": one hand fixes the pot edge, and the other hand supports the plant base and rotates counterclockwise three times. After shaking off the old soil, prune the decayed roots, and retaining the main root length of more than 15cm is more conducive to recovery.
Standard for Controlling Planting Depth
When planting, keep the junction of the root and stem 2cm below the pot edge, and after filling the substrate, gently lift the plant to allow the roots to spread out. The first watering should be thorough and include a root stimulant (recommended to dilute 1500 times), which can increase the efficiency of new root germination by over 40%.
Post-Repotting Care Strategy
Management During the Adaptation Period
After repotting, it should be placed in a semi-shaded environment for 10-15 days, maintaining a day-night temperature difference within 8°C. Fertilizing should be paused for the first 3 weeks, and then light should be gradually increased after the new leaves unfold to avoid leaf burn.
Through scientific repotting, the root renewal cycle of the Dragon Flower can be shortened to 20 days, with a significant increase in leaf fullness. It is recommended to change the potting soil every 2-3 years, coinciding with the peak growth periods of spring and autumn. Mastering the matrix ratio, potting techniques, and post-care are the three core points that will keep this "Desert Elf" showing vigorous growth continuously.
