At Lawn Synergy, we believe your lawn should be as safe as it is green. Our pet safe fertilizers are crafted without any herbicides, insecticides, or fungicides — so you can nourish your lawn with confidence. Once watered in and dry, these products are completely safe for pets and family, while delivering professional-grade results you can see.
Why Choose a Pet Safe Fertilizer?
Many fertilizers on the market combine nutrients with weed killers or pest control chemicals, which can linger on the lawn and pose risks to pets. Lawn Synergy’s line of pet-friendly fertilizers is different — we focus purely on nutrition. Our blends use premium, slow-release nitrogen sources like XCU® and naturally derived ingredients like biosolids to create a lush, dark green lawn without harmful additives.
- No herbicides, insecticides, or fungicides
- Safe for pets once watered in and dry
- Professional-grade performance for homeowners
- Slow-release nitrogen for even, steady feeding
Our Pet Safe Fertilizer Lineup

A powerhouse balanced fertilizer designed for growth, color, and recovery. With 50% slow-release nitrogen (XCU®) and 15% ammonium sulfate, it delivers fast and lasting greening while remaining gentle for pets once watered in.
Emerald 10-0-20
Ideal for strengthening turf and improving drought tolerance. This blend provides high potassium for resilience and a beautiful dark green lawn — all with pet-safe peace of mind after watering.
Starter 15-20-10
Our starter fertilizer gives new seed and sod the phosphorus boost it needs for strong root development. Perfect for new lawns or overseeding — safe for pets once watered in and the area has dried.
BioBoost 5-3-0
An all-natural organic-based fertilizer derived from premium biosolids. Excellent for building soil health and improving microbial activity — gentle on turf, safe for pets, and environmentally friendly.
NutriGreen 0-0-4
When your lawn is going dormant or you’re maintaining green color without nitrogen, NutriGreen provides potassium and iron for strength and color. Contains no pesticides or harsh salts — safe for pets and kids once watered in.
How to Use Safely
Always keep pets off the lawn during application and until the fertilizer has been watered in and allowed to dry completely. This ensures granules dissolve into the soil and prevents any accidental ingestion. Once dry, your lawn is ready for play again — greener, stronger, and pet safe.

Got Questions?
Frequently Asked.
Is Lawn Synergy fertilizer safe for pets?
Yes. All Lawn Synergy fertilizers in this collection are pet safe once watered in and dry. They contain no weed killers, insecticides, or fungicides — only turf nutrients.
Can pets go on the lawn after I apply fertilizer?
We recommend keeping pets off the lawn during application and until the fertilizer has been watered in and dried. Once the granules have dissolved and the lawn is dry, it’s safe for pets to return.
What makes Lawn Synergy fertilizers pet friendly?
Our fertilizers use nutrient-only formulations with slow-release nitrogen and no harsh chemicals. This reduces risk to pets and provides long-lasting, even feeding for your grass.
Are organic fertilizers always pet safe?
Not always. Some organic products (like bone meal or blood meal) can attract pets or cause stomach upset if eaten. Lawn Synergy’s BioBoost 5-3-0 is a carefully balanced, odor-controlled biosolid that’s both effective and safe once watered in.
