The Use of Hydroponic Fertilizers for Flower Plant Leaves
In the process of caring for hydroponic flowers, the correct use of foliar fertilizers is a key factor determining the healthy growth of plants. Unlike traditional soil cultivation, hydroponic plant roots are directly exposed to nutrient solutions, but leaf absorption is equally important. This article will systematically explain how to scientifically apply foliar fertilizers through three core steps to make hydroponic flowers have glossy leaves and extended blooming periods.
Guide to Buying Hydroponic Foliar Fertilizers
Selecting Based on Plant Characteristics
Leafy plants such as green vines and monstera require high-nitrogen formulas to promote chlorophyll synthesis, while flowering plants like hydroponic red anthuriums and orchids should choose fertilizers with higher phosphorus and potassium ratios. It is recommended to check the NPK values on the packaging and adjust the nitrogen, phosphorus, and potassium ratios according to the plant's growth stage.
Special Functional Fertilizers
For hydroponic environments, you can add anti-stress fertilizers containing humic acid or microelement fertilizers containing chelated iron and magnesium to prevent common yellow leaf diseases in hydroponic plants. Pay attention to the solubility of the fertilizer in water to avoid clogging the spray bottles.
Scientific Dilution and Spraying Techniques
Precise Mixing Method
It is recommended to use a special measuring cup and dilute the concentration specified in the instructions by half (for example, if marked 1:500, dilute to 1:1000). Hydroponic plant roots and leaves absorb simultaneously, and excessive application can cause fertilizer damage. In spring and autumn, add 0.1% of a spreader to enhance adhesion.
Three-dimensional Spraying Technique
Use a misting spray bottle, spray at a 45-degree angle 20 cm away from the leaves, focusing on the dense stomatal areas on the back of the leaves. Maintain ventilation for 2 hours after spraying to prevent water droplets from accumulating and causing diseases. Perform the operation in the evening during summer and at noon in winter.
Maintenance Cycle and Precautions
Best Fertilizing Frequency
Apply every 7-10 days during the growing period, and switch to a high-phosphorus formula 5-7 days before the blooming period. During the dormant period in winter, extend to 15-20 days/week, and using LED lights can maintain metabolic activity. For newly purchased hydroponic flowers, start fertilizing after 7 days of acclimatization.
Handling Abnormal Conditions
If the leaf tips become burnt, immediately rinse the leaves with water and add activated carbon to the nutrient solution to absorb excess fertilizer. Pause foliar fertilization during consecutive rainy days and switch to root nourishment mode.
Through scientific proportioning and precise application, hydroponic foliar fertilizers can keep flowers in the best condition. It is recommended to keep a fertilizing log, record the fertilizer responses of different varieties, and gradually develop a personalized care plan. Combine regular water changes, light control measures, and other methods to make hydroponic plants show more vigorous vitality.
