Factors to consider before buying:

1. Nutrient Composition

• Check the nutrient composition of the liquid organic fertilizer, paying attention to the N-P-K ratio (nitrogen, phosphorus, and potassium) and trace elements. Ensure it meets the specific requirements of your plants.

• Consider the source of the ingredients used in the fertilizer. Look for organic certifications and labels to ensure the product is truly organic and free from synthetic additives.
