What to Do After Daisies Bloom
As the latest blooming ornamental flower in spring, daisies always light up the courtyard with their simple and elegant posture. However, the maintenance after the flowers fade directly affects the quality of the flowers the following year. Mastering the correct daisy maintenance techniques can help the plants safely survive the summer and accumulate more nutrients. This article will systematically analyze the full process of post-bloom daisy management, from light adjustment to disease prevention.
Environmental Control and Basic Maintenance
Light Intensity Management
Since the blooming period of daisies coincides with the transition from spring to summer, post-bloom maintenance requires special attention to light control. It is recommended to move the plants to an area with scattered light in the morning and 60% shade at noon, using shade nets or moving them to a veranda to avoid leaf burning.
Water Supply Plan
Maintaining soil moisture between 40-60% is most beneficial for the plant's recovery. Use the "wet-dry" watering method, watering thoroughly when the top 2cm of soil is dry. In hot weather, combine foliar spraying, but avoid the noon period to prevent evaporation burns.
Plant Shape Management
Scientific Pruning Techniques
Complete pruning within 7 days after blooming: ① cut off the faded flowers, leaving a 1cm flower stalk; ② thin out dense branches to maintain a 30% light transmission rate; ③ retain 5 functional leaves at the base. The pruning tools need to be disinfected with alcohol, and the cut ends should be coated with wood ash to prevent infection.
Timing for Division Propagation
Healthy mother plants can be divided for propagation: select side buds with 3 fibrous roots, soak in carbendazim solution, and then transplant. The best operation period is 15-20 days after blooming, when the plants are in a semi-dormant state, and the survival rate of division can reach 85%.
Comprehensive Pest and Disease Control
Disease Plant Identification and Treatment
Focus on controlling powdery mildew and aphids: ① immediately remove and destroy diseased leaves upon discovery; ② alternately spray mancozeb and pyraclostrobin; ③ use neem-based biological preparations in the early stages of pest infestation, and use pymetrozine when severe, with a medication interval of 7-10 days.
Through scientific light, water, temperature, and fertilizer adjustments, combined with regular pruning and disease prevention, daisies can not only safely survive the summer but also sprout new buds in the fall. It is recommended to supplement with phosphorus-potassium fertilizer once a month to lay the foundation for a burst of flowers in the spring of the following year.
