Frequently Asked Questions
What do the three numbers on a fertilizer bag mean?
The three numbers represent the percentage by weight of the three primary macronutrients: Nitrogen (N), Phosphorus (P), and Potassium (K). For example, a 10-10-10 fertilizer contains 10% of each. Nitrogen promotes leafy, green growth. Phosphorus supports strong root development and flowering/fruiting. Potassium enhances overall plant vigor and disease resistance.
What is the difference between liquid and granular fertilizer?
Liquid fertilizers are fast-acting, as they are immediately available for plant uptake. They are great for a quick boost but require more frequent application. Granular fertilizers are slower-release, breaking down over time to provide a steady supply of nutrients. They are less labor-intensive but take longer to show results.
How often should I fertilize my vegetable garden?
This depends on the fertilizer type. Slow-release granules may only be needed 2-3 times per season. Liquid fertilizers might be applied every 1-2 weeks. Always follow the instructions on the product label, as over-fertilizing can harm plants and soil.
Is organic fertilizer better than synthetic?
Organic fertilizers improve soil structure and encourage beneficial microbial life, providing long-term soil health benefits. They release nutrients slowly and are generally safer for the environment. Synthetic fertilizers offer immediate, precise nutrient delivery but can contribute to salt buildup and don’t improve soil health. For edible gardens, many prefer organic options.
Can I use too much fertilizer?
Yes, over-fertilizing is a common mistake. It can “burn” plant roots, inhibit growth, lead to excessive leafy growth with little fruit, and contribute to nutrient runoff that pollutes waterways. More is not always better—always follow the recommended application rates.
