Remedial measures for wilting gardenia leaves
As a famous traditional flower in China, gardenia is deeply loved by people for its oily green leaves and fragrant fragrance. When gardenia leaves are found to be wilted, it often means that the plant is in a survival crisis. In this paper, aiming at the problem of wilting leaves of gardenia, we systematically sort out five key treatment steps to help flower friends accurately diagnose the root cause of the problem and implement scientific and effective maintenance measures. 1. Environmental adaptation and adjustment 1.1 New environmental stress treatment For gardenia that have just been potted or transplanted, it is necessary to keep the temperature and humidity of the original maintenance environment stable and avoid frequent movement of flower pots. It is recommended to rest in a scattered light environment for 7-10 days, maintaining the air humidity of more than 60%, using a humidifier or regular spray. 2. Scientific control of light 2.1 Classification management of light intensity Spring and autumn adopt the "golden 3 hours" rule: receive direct light from 9 a.m. to 12 a.m. and turn to scattered light in the afternoon. Full sunshine can be accepted in winter, and a "three-three system" is implemented in summer: 3 hours of direct exposure in the morning +3 hours of shade at noon +3 hours of scattering in the afternoon. 3. Precise temperature control 3.1 Seasonal temperature control establishes a "15-25℃ golden growth zone", and adopts a double-layer insulation method in winter: inner layer film insulation + outer layer sunshade net anti-freezing. In summer, a water curtain cooling system is used to cool the local environment by 3-5 ° C through the principle of evaporation and heat absorption. 4. Intelligent moisture management 4.1 The soil moisture detection method adopts the "knuckle detection method": the index finger is inserted into the second knuckle of the soil, and watering is needed when it is dry. It is recommended to use magnetized water or collect rainwater for irrigation. Each watering ensures that 20% of the water seeps out from the bottom of the basin to prevent salt accumulation. 5. Scientific nutrition supply 5.1 Fertilizer ratio plan implements differentiated fertilization according to the growth cycle: use N-P-K=3-1-2 formula for long-term growth, and use 1-2-3 formula for flowering. Combine it with ferrous sulfate (concentration 0.2%) irrigation once a month to maintain an acidic soil environment.
Through the above-mentioned five systematic treatment plans and the four-step maintenance method of "observation-diagnosis-treatment-tracking", wilted leaves can usually be restored to vitality in 2-3 weeks. During daily maintenance, it is recommended to establish a maintenance log to record data such as temperature, humidity, fertilization and watering to achieve precise maintenance management. Special reminder: If there is a large area of fallen leaves that need to be considered for root diseases, a timely depot inspection should be carried out.
