Can begonia be sprayed with water every day?
As a classic flower that combines ornamental value with maintenance difficulty, begonia's watering management often confuses gardening beginners. The balance between foliar spraying and root irrigation directly affects the robustness of the plant and its flowering performance. Through scientific moisture control, it is possible to avoid the risk of root rot and create a suitable microenvironment for growth.
Rational spraying maintenance plan
Humidity regulation cycle control
It is recommended to maintain a spraying interval of 3-5 days, adjusting dynamically based on environmental humidity. During the heating season in the north when the air is dry, it can be increased to every 2 days; during the plum rain season, it should be completely stopped. Focus on spraying the back of the leaves and the surrounding ground to avoid water accumulation in the flower buds that may cause mildew. Spraying during the high-temperature periods of summer can effectively reduce the temperature by 2-3°C, but it is necessary to ensure ventilation to avoid a humid and hot environment.
Systematic watering system
Seasonal watering time selection
In winter, irrigation should be done around 12 noon when the temperature difference between water and potting soil is the smallest. In summer, it is recommended to complete watering before 7 am to avoid rapid evaporation of water that may cause salt accumulation. During the transition period between spring and autumn, operations can be carried out at 9-10 am, combined with loosening the soil to promote water渗透.
Accurate water control method
Using the immersion pot method ensures uniform water penetration: place the pot in a water basin and remove it immediately when the surface soil is moist. For potted plants, the amount of water for each watering should be controlled at 1/3 of the pot's volume, and for ground plants, a circular trench should be opened 30 cm around the root system for irrigation. The sound of tapping the pot wall can be used to identify the water content; a dull sound indicates sufficient moisture.
Dynamic adjustment strategy
Keep the soil slightly moist for newly planted plants, and implement the "dry-wet" principle for mature plants. Moderately controlling water 20 days before flowering can promote bud differentiation, and immediately replenish moisture after the flowers fade. In coordination with a temperature and humidity meter, start the misting system when the air humidity is below 40%.
Adjust the plan in a timely manner by observing the leaf condition: curling leaf edges indicate a lack of water, and yellow spots on the leaf surface warn of excess. It is recommended to establish a maintenance log, recording the time of each watering and the plant's response, gradually forming a personalized moisture management plan. Reasonable water supply combined with appropriate lighting can keep the begonia green throughout the year and extend the flowering period by more than 30%.
