Store liquid fertilizers in a cool, dry place away from direct sunlight to maintain potency. Always follow the mixing instructions on the label to avoid over-fertilization, which can harm plants. Schedule regular feeding based on your plants’ growth cycles, adjusting frequency as necessary.

One common mistake is over-fertilizing, which can lead to nutrient burn and plant stress. Always adhere to recommended application rates and schedules. Neglecting to consider plant-specific nutrient needs can also hinder growth; different plants require different nutrient ratios.
