How often to water gardenia
Gardenia is loved for its pure and fragrant white flowers, and scientific watering is the key to successful maintenance. As a typical acidic plant, it has special water requirements, needing to keep the soil moist while avoiding waterlogging and root rot. This article will comprehensively analyze the rules for watering gardenias, from seasonal changes, water quality selection to maintenance details.
Seasonal watering cycle management
Spring sprouting stage watering
In the period of new bud sprouting from March to May, maintain a watering frequency of 1-2 times every 1-2 days, and water supplement is needed when the soil surface is slightly dry. Combine the application of ferrous sulfate every half month to maintain soil acidity.
Summer high temperature stage watering
From June to August, water twice a day, early morning and evening, especially when the temperature is above 30°C, place a water tray under the pot to increase humidity. Avoid watering during the high-temperature period at noon.
Autumn and winter water control techniques
After September, gradually extend to 1 time every 3 days, and use a dry-wet cycle method of 15-30 times per cycle during the winter dormancy period, choosing to water with warm water at 10 am on sunny days.
Water quality and irrigation details
Water quality treatment points
Use rainwater or tap water that has been left for 3 days, add 0.5ml of white vinegar to each liter of water to adjust the pH to an ideal range of 5.5-6.5. Avoid using alkaline water sources directly, such as well water.
Irrigation technique specifications
Use a circular irrigation method, continuing to water until water comes out of the bottom drainage hole of the pot. Combine with loosening the soil to ensure even moisture penetration and avoid the formation of a "sandwich soil" that is wet on the surface and dry underneath.
Environmental协同 management
Ventilation control standards
Keep the ventilation for more than 2 hours after watering, combine with a fan in summer to promote air circulation, and maintain an environmental humidity of 50-70%. Especially reduce the amount of watering during the rainy season.
Humidity balance strategy
Use a combination of "soaking pot method + foliar spraying" to moisturize: soak the pot in a water tray for 15 minutes once a week, and spray the back of the leaves with water in the morning and evening to increase humidity.
