The Cultivation Method of Big Flower Oxalis
Big Flower Oxalis, with its brilliant butterfly-shaped flowers and ultra-long blooming period, has become the favorite ornamental potted plant for balcony enthusiasts. To make this spring sprite continue to bloom, it is particularly crucial to master the correct maintenance methods. Next, we will break down the maintenance logic for making Big Flower Oxalis burst into bloom from basic to advanced levels.
Four Elements of Basic Maintenance
Soil Mixture and Selection
It is recommended to use a mixture of decomposed leaf soil, perlite, and vermiculite in a ratio of 5:3:2. This mixed matrix ensures nutrient supply and has good breathability. Adding bone meal as a base fertilizer during potting in spring every year can effectively prevent lodging.
Key Points for Temperature Control
Maintaining a temperature difference of 15-25°C is most conducive to the differentiation of flower buds. In summer, when the temperature exceeds 30°C, it needs to be moved to a shady place. In northern regions, special attention should be paid in winter, and when the night temperature is below 5°C, it should be moved to an indoor windowsill for maintenance.
Scientific Watering Techniques
Adopt the "moist when dry" method, watering once every 3 days in spring and autumn, and spraying in the morning and evening in summer to increase humidity. It can be judged by observing the state of the leaves: immediately replenish water when the leaves are slightly wilted, but be careful not to accumulate water that could cause the bulb to rot.
Rules for Light Management
Except for needing 50% shade in the height of summer, full sun should be provided in other seasons. Insufficient light will result in weak flower stems. It is recommended to rotate the pot 15 degrees every day to ensure that the plant is evenly exposed to light.
Advanced Flower Burst Techniques
Precise Fertilization Strategy
During the growing period, apply a diluted phosphorus-potassium liquid fertilizer (2000 times) every 10 days, and add seaweed fertilizer during the budding period to extend the blooming period. It is especially important to apply nitrogen fertilizer after flowering to replenish the bulb nutrition and store energy for the next flowering.
Pest and Disease Control Plan
Water the roots with a 800-fold solution of carbendazim every month to prevent root rot disease, and spray emamectin benzoate immediately upon discovering red spiders. Regularly prune the lower old leaves to maintain ventilation and light transmission at the bottom of the plant.
Through systematic maintenance and management, Big Flower Oxalis can burst into bloom in both spring and autumn. The key is to grasp the bulb dormancy pattern, promptly cut off the residual flowers after flowering to retain nutrients, and cooperate with scientific temperature, light, water, and fertilizer control, to let this "flowering machine" continue to bring a visual feast.
