How to care for newly purchased white magnolia
Newly purchased white magnolias often turn yellow and wilt due to environmental changes, and proper care during the acclimatization period directly affects the survival rate of the plant. As an aromatic tree with fleshy roots, white magnolia requires special attention during the early stages of transplanting. This article will systematically analyze key care points from root management to environmental control.
Core care strategies for white magnolia during the acclimatization period
Soil substrate replacement specifications
It is recommended to observe the plant's condition for 7-10 days before repotting, using a substrate mixture of humus soil: perlite: pine needles in a ratio of 5:3:2. When repotting, retain 1/3 of the original soil around the root ball, cut away the coiled brown old roots, and the new soil should be disinfected with carbendazim.
Branch and leaf pruning standards
Use a 45-degree oblique cutting method to remove the top 1-2 nodes, focusing on pruning intersecting and weak branches. Immediately seal the cuts with wood ash to prevent sap loss. Retain 6-8 main branches to form an umbrella-like structure, with the pruning amount not exceeding 30% of the total leaf mass.
Water management technical requirements
During the acclimatization period, use the immersion method for watering: place the pot in a water tray for 20 minutes, maintaining a substrate moisture level of 40%-50%. Use the bamboo stake test method to determine if watering is needed; if there is no soil adhering to the stake after 2 hours, additional water is required. Special attention should be given to setting up a rain shelter during the rainy season.
Light environment adjustment plan
Set up a double-layer shade net to achieve 60% light transmission, and expose the plant to 2 hours of direct sunlight in the morning. Use an ultrasonic humidifier to maintain 65% air humidity, and keep the day-night temperature difference within 8°C. Rotate the pot by 15° every 3 days to ensure even light exposure.
After 30 days of systematic care, the new white magnolia roots can reach 5-7cm, the leaf color turns to a lustrous green, and new buds emerge. Regular application of EM菌 liquid can enhance stress resistance, and once the plant is stable, it can be transferred to a regular care mode.
