How to Care for Jasmine Plant After Buying
The care of newly purchased jasmine directly affects the survival rate of the plant and the quality of flowering. This article systematically analyzes the key points of management during the acclimatization period and the causes of yellow leaves for two common forms of jasmine seedlings purchased online or from flower markets, helping beginners quickly grasp the core care techniques.
Key Steps for Transplanting Jasmine
Activating Treatment for Bare-Root Seedlings
Bare-root seedlings purchased online need to be checked for root activity: main roots with a diameter ≥ 2mm and a milky white color indicate a healthy state. Soak in warm water at 30°C for 6-8 hours, with the option to add 50ppm indole butyric acid to promote root growth. Use a soil mix of peat: pine bark: perlite = 5:3:2, with a pH value controlled between 5.5-6.5.
Soil Replacement Strategy for Potted Seedlings
Potted seedlings from physical stores need to undergo soil testing: if the soil is compacted or contains construction sand particles at a depth of 2cm, it should be replaced immediately. Retain 1/3 of the original soil around the roots, and mix new soil with decomposed sheep manure (10% proportion) to enhance fertility. After repotting, cover with a black shade net (70% light blocking) for 3 days.
Yellow Leaf Pathological Diagnosis System
Environmental Stress-Induced Yellowing
Yellowing caused by transportation usually occurs in the lower and middle mature leaves, with uniform yellowing between the veins. Use a sterilized scissor to cut at a 45-degree angle from the base of the leaf petiole and apply plant ash to the wound. Simultaneously spray a mixture of 0.1% ferrous sulfate and 0.2% urea solution, applying twice a day for 3 days.
Identification of Pathological Yellow Leaves
If new leaves show net-like yellow spots or crispy edges, be alert to red spider mites or root rot disease. Spray the underside of leaves with a 20% pyridaben emulsion diluted 2000 times, and combine with a 50% carbendazim solution diluted 800 times for root irrigation, once every 5 days for 3 weeks. Covering with a transparent plastic bag at night to maintain 85% humidity can enhance the efficacy of the treatment.
By accurately diagnosing the causes of yellow leaves and adopting differentiated care, combined with intelligent monitoring of temperature and humidity (daytime 25-28°C/nighttime 18-20°C, humidity 60-75%), jasmine can recover its growth vitality within 30 days and form new flower buds after 45 days. Regular use of EM bacteria solution for root irrigation can continuously improve the rhizosphere microenvironment, fundamentally preventing the recurrence of yellow leaves.
