Fertilizer 101

Whether you’re brand‑new to lawn care or just brushing up your skills, understanding how fertilizer works and how to use it can make a huge difference in how your lawn looks and performs. In this article, we’ll break down the basics of lawn fertilization in easy‑to‑understand terms — and show you how specific products from our store can help you get results you’ll be proud of.

What Is Fertilizer and Why Does Your Lawn Need It?

Your lawn needs nutrients — just like you do! Fertilizers are products that supply your grass with essential nutrients that might be missing from your soil. The three most important nutrients are:

• Nitrogen (N) – Promotes lush, green leaf growth

• Phosphorus (P) – Supports strong root development

• Potassium (K) – Helps your grass withstand stress like heat, drought, disease, and cold

These nutrients are shown on every fertilizer bag as three numbers (called N‑P‑K) — for example, “24‑0‑3” means 24% nitrogen, 0% phosphorus, and 3% potassium.

When to Fertilize Throughout the Year

Different times of year call for different lawn needs:

• Early Spring: Start with a crabgrass preventer before weeds germinate.

• Late Spring/Early Summer: Feed actively growing grass and control broadleaf weeds.

• Summer: Use a balanced fertilizer that sustains growth even in heat.

• Fall: Feed for root strength and winter hardiness.

Applying fertilizer at the right time ensures nutrients are available when your lawn needs them most.

Tips for Successful Fertilizing

✔ Measure your lawn area before applying fertilizer — more isn’t better!
✔ Use a broadcast or drop spreader for even coverage.
✔ Apply on calm, dry days — watering in afterward helps nutrients reach roots.
✔ Avoid over‑fertilization, which can burn grass and cause runoff.

Fertilizing doesn’t need to be complicated. By choosing the right Endure products and applying them at the right time, you’ll give your grass the nutrients it needs — whether you’re a first‑timer or seasoned DIYer.
