Balcony Begonia Care Techniques: Begonia Lighting and Fertilization Key Points

How to grow Begonia on the balconyAs a traditional ornamental flower loved by many, growing Begonia on the balcony not only decorates the home but also purifies the air. Mastering scientific maintenance methods can keep the potted Begonia vigorous throughout the year. This article will systematically explain the key points of indoor cultivation from light management to pruning techniques.Begonia Light Management StandardsLight Duration and IntensityEnsure 4-6 hours of scattered light daily, and it can be exposed to full sunlight in spring and autumn. During the blooming period, the plant is more sensitive to light, so it is recommended to use a shading net to filter the strong midday sunlight and avoid burnt edges on the petals.Summer Protection MeasuresDuring the high-temperature period from June to August, move it to the east-facing balcony and use gauze to block direct sunlight. Rotate the pot every 3 days by 45 degrees to ensure uniform growth and prevent a lopsided crown.Begonia Water Control PlanSeasonal Irrigation CycleDuring the growing season (March-May), keep the soil moist and water 2-3 times per week; during the dormant period (November-February), extend it to 10 days per watering. It is best to use rainwater or settled tap water with a pH of 6.0-6.5.Maintaining Air HumidityWhen the relative humidity is below 50%, supplement the leaf surface with a mist sprayer in the morning and evening, taking care to avoid the flowering parts. You can place a pebble water tray at the bottom of the pot to enhance local humidity.Begonia Nutrition Supply SystemImproving the Substrate RatioChange the potting soil every 2 years, using a mixed substrate of peat soil: perlite: decomposed leaf soil in a ratio of 5:3:2. Add 150g of bone meal per pot as a long-acting base fertilizer when repotting.Fertilization Plan During the Growing SeasonApply high-phosphorus water-soluble fertilizer (10-30-20) during the bud differentiation period (February-March), and switch to balanced fertilizer (20-20-20) after flowering. Stop fertilizing during the winter.Begonia Shaping and Pruning ArtStructural PruningBefore early spring germination, thin out intersecting and weak branches, retaining 3-5 main branches to form an umbrella-like structure. Disinfect pruning tools with alcohol and apply healing agent to the cuts.Post-Flowering ArrangementRemove the withered flowers in time to avoid nutrient consumption, leaving 2-3 buds at the base. Pinch the new branches when they reach 15cm to promote branching.Through scientific light control, precise water and fertilizer management, and regular shaping and pruning, the Begonia on the balcony can achieve four-season ornamental value. It is recommended to check the back of the leaves monthly to prevent red spider mites and use organic silicon additives to enhance the plant's resistance, allowing this traditional famous flower to thrive in modern homes.
