Geraniums, with their bright colors, dense flowers, and unique aromas, have always been a favorite among gardening enthusiasts. However, the high temperature and humidity of summer often make geranium maintenance challenging, and many flower lovers find that their geraniums begin to languish in summer, or even stop flowering. Don't worry, just master the following "3 things" and your geraniums will be full of energy and bloom into a brilliant flower bulb even in hot weather!
1. Control lighting and shading
Strong sunlight in summer is the enemy of geraniums, and too strong direct light can easily cause leaf burns, fading of flower color, and even wilting of the whole plant. Proper shading is key.
Specific operation: Place geraniums on the east-facing or west-facing balconies and windowsills, which can not only ensure that there is enough soft light in the morning or afternoon, but also avoid the direct exposure of the scorching midday sun. If you must face south, consider using shade nets or thin curtains for proper shading.
2. Rational water and moisturizing
Geraniums are drought tolerant but not waterlogging, and the high temperature in summer evaporates quickly, increasing water demand, but overwatering is also dangerous. Keeping the soil slightly moist without standing up for water is central.
Specific operation: follow the principle of "see dry and see wet", that is, water when the topsoil is dry, and water thoroughly, so as to avoid frequent watering and lack of oxygen in the roots. In summer, morning and evening sprays can be added to increase air humidity and promote foliar cooling.
3. Adjust fertilization and pruning
Geraniums grow vigorously in summer, and proper fertilization can promote flower bud formation, while timely pruning can maintain plant form, promote ventilation, and reduce pests and diseases.
Specific operation: Use a low concentration of liquid fertilizer, apply 1-2 times a month, focus on phosphorus and potassium fertilizer, and promote flower bud differentiation and flowering. At the same time, the withered flowers and overly dense branches and leaves are pruned in time to supply the new shoots and flowers with concentrated nutrients. Pay attention to tool disinfection when pruning to prevent infection.
Maintaining geraniums in summer may seem challenging, but with just the right light control, water management and proper fertiliser pruning, you can make your geraniums thrive in the scorching heat and bloom with stunning flower bulbs.
