Four elements of rhododendron flowering management
Cultivating a pot of azaleas in full bloom indoors is a favorite for many gardening enthusiasts. This plant, known as the "Beauty of Flowers", is full of beautiful branches when it blooms. However, if it is not properly maintained, problems such as shortening the flowering period and early fading of flowers often occur. Mastering scientific maintenance methods can allow rhododendrons to bloom for a more lasting beauty indoors. Light control rule The light cycle regulates the initial appearance of flower buds to maintain scattered light for 6 hours a day, and use a gauze curtain with a light transmittance of 40%. When the bud begins to expand, gradually shorten it to 4 hours of light per day to avoid direct exposure causing the petals to be scorched. The light intensity can be maintained in the range of 8000-12000lux with the help of a plant fill light. Orientation selection standard Place it on the east-facing window sill in spring and autumn, turn to the north-facing bay window in summer, and move to the south-facing balcony in winter. Turn the flowerpot 45 degrees every two weeks to ensure balanced growth of the plant type. Pay attention to the condition of the leaves and adjust the position in time if yellowing occurs. Water management plan Precise watering techniques use immersion basin method to replenish water, which is carried out every Tuesday and Friday at 10 a.m. The water temperature should be consistent with room temperature, soak for 15 minutes each time and drain. Configure 0.1% ferrous sulfate solution for irrigation once a month to maintain an acidic soil environment. Tips for humidity control Place a pebble water tray on the bottom of the flower pot to maintain the air humidity of 60%-70%. Use an atomizing humidifier at noon to avoid spraying flowers directly. Turn on the circulation fan during the rainy season to promote air circulation and prevent the growth of mold. The temperature adjustment strategy controls the temperature difference between day and night to maintain it at 18-22℃ during the day and drop it to 12-15℃ at night. Use smart temperature control equipment to avoid sudden changes in temperature exceeding 5℃. During winter heating, flower pots need to be more than 2 meters away from the radiator. Key points for seasonal transition: Spring and autumn pay attention to guard against the cold in late spring, and prepare insulation films for emergency response. When the air-conditioned room is placed in summer, the setting temperature shall not be lower than 20℃. Natural cooling can be achieved by watering on the ground, and the daily temperature difference is controlled within 8℃. Pest and pest control system biological control program hangs yellow sticky insect boards to monitor thrips and releases predatory mites to control red spiders. Spray the back of the leaves with garlic extract (1:20) every week to prevent aphids from invading. Clean dead branches and rotten leaves in time to block the spread of bacteria. Chemical control specifications found that flower rot were immediately removed and mancozeb and azoxystrobin were used alternately. When scale insects break out, they are physically removed with a 75% alcohol cotton swab, and then sprayed with spirotetramate. All medicaments must be used to avoid the full flowering period and dilute strictly according to the instructions.
Through systematic maintenance and management, the indoor rhododendrons flowering period can be extended to 45-60 days. The key is to grasp the dynamic balance of environmental factors, establish an observation record book, and record each maintenance operation in detail. When flowers begin to wither, prune the remaining flowers in time and replenish phosphorus and potassium fertilizers to accumulate energy for the next round of blooming.
