What Is 10-10-10 Fertilizer?

Before we jump into shelf life, let’s make sure we’re all on the same page. 10-10-10 fertilizer is a balanced fertilizer. The numbers on the bag (10-10-10) represent the percentages of the three primary macronutrients essential for plant growth: Nitrogen (N), Phosphorus (P), and Potassium (K).

• Nitrogen (N): Promotes leafy growth and green color.
• Phosphorus (P): Supports root development, flowering, and fruiting.
• Potassium (K): Aids in overall plant health, disease resistance, and water regulation.

A 10-10-10 fertilizer means it contains 10% nitrogen, 10% phosphorus (as phosphate), and 10% potassium (as potash) by weight. The remaining 70% is usually made up of filler material, which helps with even distribution and prevents the fertilizer from burning the plants. These fillers can vary, but common ones include sand, clay, and other inert substances.

Why Use 10-10-10 Fertilizer?

10-10-10 is a versatile fertilizer suitable for a wide range of plants. Because it’s balanced, it provides a little of everything, making it a good choice for general use. It’s often used for:
