How to raise Rieger Begonia in spring
As an ornamental plant that blooms all year round, it is particularly important to maintain Rieger Begonia in spring. Temperature fluctuations and changes in nutrient requirements this season directly affect the quality of flowering. Mastering scientific maintenance methods can make plants stronger and the flowering period more lasting. This article systematically explains the secrets of spring maintenance from three dimensions: nutrition management, environmental regulation and moisture control. The core points of spring maintenance Scientific fertilization strategy requires precise fertilization during the peak spring growth period: 1. Adult plants (more than 2 years old) are mainly formulated with phosphorus and potassium fertilizers. It is recommended to use potassium dihydrogen phosphate solution (concentration 0.1%) for watering every 15 days, combined with foliar spraying Huaduo No. 2 2. The focus is on applying nitrogen to young plants. It is recommended to use decomposed soybean cake water and compound fertilizer alternately, no more than 3 times a month. After fertilization, loosen the soil and ventilate the air to avoid fertilizer accumulation and cause root burning. Intelligent temperature control plan Rieger Begonia is sensitive to temperature and needs to be managed in layers: ·In early spring (March-April), keep it above 12℃ at night, cover it with insulation film or move it indoors·Mid-spring (mid-April) Stabilize at the optimal growth range of 18-22℃·Late spring (May) start the cooling program when it exceeds 26℃: - Spray moisturize in the morning and evening (Maintain humidity at 60-70%)-Build a sunshade net to filter strong light-place a water pan on the bottom of the basin. The evaporative cooling precision irrigation system adopts the "three-look" watering method: ① Look at the substrate: replenish water when the surface of the peatsoil turns white and the weight becomes lighter ② Look at the weather: Water in the morning on sunny days, delay on rainy days ③ Look at the status: New leaves are slightly wilted and immediately replenish water. Advanced skills: - Use 25 ° C warm water to slowly water along the edge of the basin-Use rainwater to rinse the leaf salt every month-Raise the flowerpot when accumulating water to enhance drainage Through systematic spring maintenance, Rieger Begonia can not only safely spend the spring, but also accumulate sufficient nutrients to achieve Continuous flowering. Pay special attention to avoid direct strong light at noon, and regularly inspect the back of the leaves to prevent pests and diseases such as red spiders. By mastering these essence of maintenance, you can cultivate high-quality potted plants with colorful flowers.
