When your lawn faces the toughest conditions, heat, drought, or disease, ordinary fertilizers aren’t enough. Yard Mastery’s 5-0-15 Life Support is engineered as the ultimate stress management tool for your turf, combining advanced nutrition with powerful soil-building ingredients. Here’s how Life Support works, why it’s a standout for challenging seasons, and how it compares to Yard Mastery’s 7-0-20 Stress Blend.
What Makes Life Support 5-0-15 Special?
Formulated for Stress Recovery and Resilience
Life Support is a natural-base, 2-in-1 granular fertilizer and soil amendment. It’s high in potassium and magnesium, key “electrolytes” for plant health, plus humic acid, kelp extract, and plant protein hydrolysates. This blend is designed to help your lawn recover from and resist environmental stressors, ensuring a vibrant, resilient turf even in the harshest conditions.
Key Ingredients Explained:
- Low Nitrogen, High Potassium:
With only 5% nitrogen, Life Support avoids growth surges during heat, while 15% potassium (from premium sulfate of potash) strengthens cell walls and improves drought and disease resistance. - Magnesium and Sulfur:
At 3.66% magnesium and 11.9% sulfur, Life Support delivers more of these nutrients than almost any consumer turf product. Magnesium is essential for chlorophyll (the green pigment in grass), while sulfur boosts color and helps plants use nitrogen more efficiently. - Humic Acid and Kelp Meal:
These natural biostimulants improve soil structure, increase nutrient uptake, and help buffer soil pH swings. Kelp also helps turf recover from stress and promotes root growth. - Protein Hydrolysates (Peptides):
These plant-based amino acids support stress recovery and up-regulate antioxidant enzymes, helping your lawn bounce back from heat, drought, or disease.
Life Support vs. 7-0-20 Stress Blend: Which Stress Fighter Is Right for You?
Both Life Support 5-0-15 and 7-0-20 Stress Blend are designed to help your lawn through tough times, but they have some key differences:
| Feature | Life Support 5-0-15 | 7-0-20 Stress Blend |
|---|---|---|
| Nitrogen Content | 5% (very low, for minimal growth surge) | 7% (low, but slightly more for recovery) |
| Potassium Content | 15% (high, for stress protection) | 20% (very high, for water retention and stress) |
| Magnesium & Sulfur | 3.66% Mg, 11.9% S (very high) | Contains magnesium and micronutrients, but lower S |
| Bio-Stimulants | Humic acid, kelp, protein hydrolysates | Bio-Nite™ (feeds soil microbes) |
| Iron Content | None | 3% Iron (for a quick color pop) |
| Soil Health Focus | Strong (improves organic matter, CEC) | Strong (Bio-Nite™ feeds microbes) |
| Best Use | Summer stress, drought, disease, transition | Heat, drought, freeze recovery, color pop |
| Staining Risk | Will not stain concrete | May stain if not swept from hard surfaces |
In summary:
- Life Support is your go-to for deep stress recovery, especially if you want to boost soil health, root mass, and long-term resilience. Its high magnesium and sulfur content make it ideal for lawns that struggle with pale color or need extra help during extreme heat or disease.
- 7-0-20 Stress Blend is excellent for quick color improvement (thanks to iron), water retention, and general stress relief. It’s a great all-around choice for both cool- and warm-season lawns, especially if you want a visible “pop” of green.

Why Life Support Works
Life Support’s low-nitrogen, high-potassium formula prevents unwanted growth surges during stressful periods, while magnesium and sulfur boost color and plant health.
