How to Care for Newly Bought Osmanthus
How to help newly acquired osmanthus adapt to the environment quickly? As one of the top ten famous flowers in Chinese tradition, osmanthus is deeply loved for its fragrant aroma and auspicious meaning. This article systematically sorts out the key points of the entire process from acceptance to daily care for newly purchased osmanthus, helping新手花友 avoid common misunderstandings.
Management of Adaptation Period for Newly Bought Osmanthus
Plant Inspection and Pre-treatment
Immediately after opening, check the roots and branches: cut off the blackened and rotting roots and the sick and weak branches, retaining the main root length of 15-20cm. Soak in water at 25℃ for 2-3 hours to restore root vitality, and then let the surface of the roots dry slightly before potting.
Environmental Control during the Acclimatization Period
Maintain a constant temperature of 25℃, avoiding direct sunlight. Use a transparent plastic bag to cover the pot to create a small environment with 80% humidity, and ventilate for 1 hour daily. This stage lasts for 7-10 days, and gradually remove it after new leaves sprout.
Daily Maintenance Tips for Osmanthus
Light Control Plan
Keep it in full sun in spring and autumn, and shade 30% from 10:00 to 15:00 in summer. Ensure that there is direct sunlight for at least 8 hours daily during the bud differentiation period (August to September), and auxiliary lights can be used.
Scientific Watering System
Adopt the principle of "water when dry and wet": 3 times/week in spring and autumn, morning and evening each time in summer (avoiding noon), and once every 7 days in winter. For potted plants, use the immersion pot method, with water level reaching 1/3 of the pot height, and soak for 15 minutes.
Temperature Management Points
The optimal growing temperature is between 18-28℃, and maintain above 0℃ in winter. The day and night temperature difference during the bud stage should be greater than 8℃, which can be achieved by opening windows at night. Strengthen ventilation when it is above 30℃.
Advanced Maintenance Secrets for Osmanthus
Nutrition Supply Strategy
Apply decomposed cake fertilizer (N-P-K=5-3-2) every 10 days during the germination period, and switch to applying monopotassium phosphate (diluted 1500 times) before flowering. Pay attention to applying thin fertilizer frequently, and supplement calcium with bone meal every March, June, and September.
Soil Improvement Plan
Prepare a golden ratio substrate: 4 parts of decomposed leaf soil + 2 parts of river sand + 1 part of珍珠岩 + 1 part of pine needles. Add 5% sulfur powder every 2 years when repotting to adjust the pH to 5.5-6.5.
Through systematic maintenance management, newly purchased osmanthus can bloom in the same year. Remember the three principles of "patience during acclimatization, sufficient light, and seasonal watering", and regularly prune to maintain the tree shape, which will definitely make the golden osmanthus bloom and fill the courtyard with fragrance.
