Attention Points for Repotting茉莉
As a representative of traditional Chinese fragrant flowers, repotting茉莉 is a key maintenance step to maintain vigorous plant growth. This article systematically analyzes the complete operation process of repotting茉莉, providing professional advice based on plant growth characteristics to help flower enthusiasts master the correct timing and operation standards, ensuring healthy root development and achieving the cultivation goal of fragrant flowers and lush leaves.
The Core Four Steps of Repotting茉莉
Scientific Repotting Techniques
Stop watering 72 hours before repotting, and it is safer to operate when the potting soil is half-dry. Use a garden spade to loosen the soil along the pot wall, and when inverting the pot, support the base of the main stem with the palm of the hand to avoid mechanical damage. For plants with severely entangled roots, use a bamboo skewer to assist in loosening the soil, retaining 1/3 of the protective heart soil for better recovery.
Root Pruning Standards
Retain new white roots with a diameter ≤ 2mm, and cut off the lignified old roots at the branching point. The cut should be smooth, and it is recommended to use pruning shears disinfected with alcohol. Simultaneously prune dense branches and leaves, retain 3-5 nodes on the main stem, and keep 4-6 top leaves, which can reduce transpiration consumption.
Soil Preparation Essentials
The new pot diameter should be 5-8cm larger than the original pot, and it is recommended to use earthenware or green mountain pots. The matrix should be mixed in the ratio of decomposed leaf soil: perlite: pine phosphate = 5:3:2, with a 3cm layer of ceramic stones at the bottom for drainage. When filling the soil, layer it and compact it, lifting the plant every 3cm to keep it upright, ensuring a 2cm space between the root neck and the pot edge.
Root Watering Method
After repotting, the first watering should use the immersion pot method, placing the pot in a water basin for 15 minutes. Subsequent maintenance should maintain a diffused light environment, and spray the leaf surface with water every morning and evening for the first three days. Avoid applying any fertilizer before new buds sprout. It is recommended to operate at 15-25°C in spring, with a survival rate of over 95%.
Through scientific repotting operations,茉莉 can quickly establish a new root system. It is particularly important to avoid direct sunlight for 30 days after repotting, regularly check the soil moisture, and when new branches reach 10cm in length, they can be transferred to normal maintenance. The reasonable repotting cycle is once every 1-2 years, which can effectively prevent growth obstacles caused by soil compaction.
