How to Care for Begonias in Summer
In the midst of summer, caring for begonias presents numerous challenges. As a typical shade-loving plant, its tender leaves and sensitive roots are particularly prominent in high temperatures. Mastering scientific care methods can not only help the plants survive the summer safely but also promote more vibrant blooms in the autumn. The following provides a systematic analysis of key summer care points from four core dimensions.
Managing Begonia Sunlight in Summer
Creating a Diffused Light Environment
Direct sunlight during the summer noon can cause leaf edge burning, so it is recommended to use double-layer shading nets or place the plants on a north-facing balcony. Gentle light before 9 am and after 5 pm can be retained to promote photosynthesis.
Monitoring Light Intensity
Use a lux meter to measure and maintain an ideal range of 10,000-15,000 lux. When the ambient temperature exceeds 32°C, additional physical shading devices like bamboo curtains need to be added.
Begonia Water Regulation Plan
Optimizing Watering Frequency
Use the 'soaking pot + misting' double补水 method: soak the pot in a water basin for 10 minutes twice a week, combined with misting the leaf surface in the morning and evening. Maintain a substrate humidity of 60%-70%, avoiding waterlogging and root rot.
Key Points for Water Treatment
Use tap water or rainwater that has been standing for 24 hours, and the water temperature should be similar to room temperature. Adding 0.1% wood vinegar can adjust the pH to a slightly acidic range of 5.5-6.5.
Begonia Temperature Control Strategy
Maintain a daytime temperature of 22-25°C and an acceptable nighttime temperature difference of 18°C. When the temperature is >30°C, use the 'terracotta pot nesting method': fill the outer container with moist sphagnum moss to cool through evaporation.
Building a Begonia Ventilation System
Air Circulation Plan
Indoor care requires maintaining an air velocity of 2m/s, and it is recommended to install a circulating fan and set it to rotate regularly. Outdoor planting should set up a 40cm elevated planting platform to promote air exchange at the bottom.
Humidity Balancing Techniques
Combine with a smart humidifier to keep the air humidity between 65%-75%, avoiding high temperature and humidity that can trigger (T-J) disease. Use garlic extract solution for preventative spraying once a week.
Through scientific regulation of light, water, temperature, and air, begonias can not only safely survive the summer but also accumulate nutrients to develop flower buds. It is recommended to check the leaf backs and stem nodes regularly and deal with pests like spider mites promptly. Gradually increase the duration of sunlight before autumn to prepare adequately for the blooming period.
