Caring for Flowers on a Rainy Day
Continuous rainy weather makes flower lovers worried, with issues such as moldy leaves,积水 in pots, and frequent diseases following one after another. Statistics show that the mortality rate of plants during the rainy season is 40% higher than usual, making scientific maintenance key. This article systematically sorts out 5 core solutions to help you build a rainy season plant protection system.
Rainy Season Water Accumulation Solutions
Smart Water Control and Physical Isolation
Soil moisture should be kept within the range of 60%-70%, and it is recommended to use pots with drainage holes. For example, a pot with a diameter of 30cm needs 3 drainage holes with a diameter of 1cm. Outdoor plants can adopt a stepped elevation method: place 3cm thick ceramsite at the bottom, charcoal granules in the middle layer, and volcanic rock to isolate the bottom of the pot.
Air Circulation System Optimization
It is recommended to maintain a wind speed of 0.3-0.5m/s in indoor environments, and set the circulating fan to run for 6 hours a day. For severely waterlogged plants, a three-step rescue method should be adopted: ① Tilt 45° to invert and drain; ② Replace the pot with a mixture of pine needle soil and perlite (2:1); ③ Encase in a bag for 72 hours to slow down seedling growth.
Plant Disease Prevention and Control System
Triple Protection Against Fungal Diseases
Establish a prevention-treatment-care chain for black spot disease: spray a 1:800 solution of carbendazim every week, and use a mixture of mancozeb and difenoconazole at the initial stage of the disease. During the key prevention and control period of (T-J) disease, maintain a pH of 6.0-6.5 and apply bamboo vinegar solution monthly to improve the soil.
Strategies for Physiological Diseases
Implement sulfur powder prevention method during the high incidence period of powdery mildew: mix 5g of sulfur powder per square meter of potting soil. For wilt disease prevention, it is recommended to use varieties with high resistance, such as 'Riku' and 'Purple Ball' for clematis, combined with soil improvement using wood ash (200g/m²).
Comprehensive Pest Management Solutions
Environmental Regulation and Physical Control
Establish a humidity warning system, and start the dehumidifying equipment when the air humidity exceeds 80%. Use the segmented combustion method for mosquito coils: light 1/4 segment daily from 19:00-21:00, combined with yellow sticky insect boards (20cm×25cm) for three-dimensional control.
Accurate Application of Biological Agents
For the control of scale insects, it is recommended to use a 75% alcohol gradient therapy: spray the entire plant for the first time, then spot-spray after 72 hours. Combine the release of ladybugs (2-3 per pot) to establish a biological control system for ecological pest control.
Through a three-dimensional maintenance system of humidity monitoring, disease warning, and pest control, the mortality rate of plants during the rainy season can be reduced by up to 78%. It is recommended to establish a maintenance log, recording daily temperature and humidity and treatment measures. Special varieties such as kaffir lilies need to set up additional rainproof shelters and use drip irrigation systems for precise water supplementation.
