How to Care for Golden Edge Daphne in Summer
Golden Edge Daphne is loved by horticulture enthusiasts for its rich fragrance and gold-edged leaves, but the high temperature and humidity of summer often present challenges to the plant's growth. Mastering the correct summer care methods can not only help Golden Edge Daphne survive the summer safely but also promote bud differentiation in autumn. This article will systematically analyze key care points from five dimensions.
One, Growth Characteristics of Golden Edge Daphne in Summer
1. Sensitivity to Temperature and Humidity
When the temperature exceeds 28°C, the plant enters a semi-dormant state, during which the root absorption capacity is weakened, and the air humidity should be maintained between 60%-70%. It is recommended to install a thermometer and hygrometer on the balcony for real-time monitoring.
2. Changes in Light Demand
In summer, avoid direct sunlight from 11:00 to 15:00, and use double-layer shading nets to filter 60% of the light. The east-facing windowsill is the best placement position, as it can receive morning light and avoid afternoon sun.
Two, Four Elements of Scientific Care
1. Substrate Improvement Plan
According to the ratio of decomposed leaf soil: river sand: vermiculite = 4:3:3, add 5% pine bark particles to enhance breathability when repotting every two years. A 3cm thick layer of ceramsite should be placed at the bottom of the pot for drainage.
2. Smart Watering Strategy
Use the "fingertip test": when the second joint of the index finger inserted into the potting soil is dry, water thoroughly. Watering should be done before 7 a.m., and the water temperature should be consistent with the ambient temperature.
3. Nutritional Supplement Plan
Between June and August, spray 1 time of 1500 times potassium dihydrogen phosphate foliar fertilizer monthly, and combine with EM bacteria solution for root irrigation (diluted 1:500) to enhance stress resistance. Solid fertilizers are prohibited.
4. Environmental Control Techniques
Place water trays around the pots to cool and humidify through evaporation. Use a circulating fan to maintain air circulation but avoid direct blowing on the plant.
Three, Handling Special Issues
1. Emergency Treatment After Rain
If there is a heavy rain, immediately tilt the pot to pour out the accumulated water and use an electric fan to assist in drying the moisture in the leaf heart. After consecutive rainy days, use a 800 times solution of carbendazim for root irrigation to prevent root rot.
2. Solution for Burnt Edges
When the leaf edges become scorched, promptly cut off the damaged leaves and seal the cuts with a waxy wound healer. Simultaneously check if the roots are rotting and replace the breathable substrate if necessary.
Through scientific light control, precise watering, and reasonable fertilization, combined with pest and disease prevention, Golden Edge Daphne can maintain a healthy state in summer. It is recommended to conduct a comprehensive check every 10 days, record the growth changes of the plant, and adjust the care plan in a timely manner. After mastering these techniques, you will be able to enjoy the fragrant flowers of Golden Edge Daphne blooming in autumn.
