Understanding Spring Fertilizer: What Each Ingredient Does for Your Lawn

What's in spring fertilizer? and what does it do?

Applying a spring fertilizer is one of the best ways to jumpstart your lawn’s growth after winter. But what exactly is in that bag of fertilizer, and why does it matter? Most fertilizers contain three primary nutrients—nitrogen (N), phosphorus (P), and potassium (K)—each playing a vital role in your lawn’s health. Let’s break down what these nutrients do and why they’re essential for a strong, vibrant lawn.

Nitrogen (N) – Promotes Lush, Green Growth

Nitrogen is the most important nutrient in a spring fertilizer, as it fuels rapid grass growth and enhances that rich green colour. After winter dormancy, your lawn needs a boost to kickstart photosynthesis and produce strong, healthy blades. Too little nitrogen can leave your grass looking pale and thin, while too much can lead to excessive top growth at the expense of root development. A balanced turf care program ensures your lawn gets just the right amount.

Phosphorus (P) – Strengthens Roots

Phosphorus is responsible for root development, helping new grass establish itself and existing lawns grow deeper, stronger roots. While established lawns don’t need much phosphorus, newly seeded or sodded lawns benefit greatly from it.

Potassium (K) – Builds Stress Resistance

Potassium acts like an immune system booster for your lawn, making it more resistant to stressors like drought, disease, and cold temperatures. In early spring, potassium helps grass transition from winter dormancy and prepares it for the heat of summer. Without enough potassium, your lawn may struggle to handle extreme weather or recover from damage.

Other Important Ingredients in Spring Fertilizer

• Calcium & Magnesium – Improve soil structure and overall grass health.

• Iron – Enhances deep green colour without excessive growth.

• Micronutrients (Zinc, Manganese, etc.) – Help with enzyme functions and overall turf vitality.
