Pet Safe Lawn Fertilizer

Feed your lawn — protect your pets. These fertilizers contain no herbicides, insecticides, or fungicides and are safe once watered in and dry.

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

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.

Frequently Asked Questions

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.
