Fertilizers are essential for vibrant, thriving trees and lawns, but not all fertilizers are created equal when it comes to safety. In Calgary, where families and pet owners often share their yards with young children and four-legged companions, choosing a safe, effective fertilization method is critical.

Let’s explore why kelp stands out, and how Evergreen LTD prioritizes safety without compromising on results.

Why Fertilizer Safety Matters in Calgary Yards

Whether synthetic or organic, fertilizers carry some risk:

Synthetic fertilizers may include pesticides or herbicides that can be toxic.
Organic options like bone or blood meal can still attract pets and cause digestive issues.
Granules of any kind may irritate skin or be accidentally ingested by kids.

For homeowners in Calgary, especially those with kids and pets playing outside, it’s about choosing the right organic fertilizer.

Why Evergreen LTD Uses Kelp Fertilizer

At Evergreen, we choose kelp-based fertilizer for many of our residential and commercial clients. Here’s why:

Gentle and Safe for Families

Kelp meal and seaweed extracts are vegetarian and don’t carry the strong smells that attract dogs and other animals. Unlike bone or fish meal, kelp is less likely to be ingested by curious pets.

No Harsh Chemicals

Our kelp fertilizer is free of synthetic herbicides, pesticides, or heavy metals, common culprits in fertilizer-related health risks. This lowers the risk of chemical exposure for both humans and animals.

Fast Absorption and Shorter Re-Entry Time

Kelp-based sprays and granules are absorbed quickly into the soil. In most cases, safe re-entry into treated areas is possible within 24–48 hours, compared to 72 hours for many chemical options.

Rich in Micronutrients

Kelp provides essential nutrients like potassium and trace minerals, which support root health, drought tolerance, and overall tree vitality, all without overloading the soil with nitrogen.

Kelp meal and seaweed extracts are vegetarian and don’t carry the strong smells that attract dogs and other animals. Unlike bone or fish meal, kelp is less likely to be ingested by curious pets. That said, no fertilizer is completely risk-free, kelp can still cause irritation or digestive upset if mishandled or ingested, especially in large amounts.

How Evergreen Applies Kelp Fertilizer Safely

Our ISA-certified arborists follow strict protocols to ensure your yard stays both beautiful and safe:

Pre-application planning: We schedule treatments when weather conditions support quick absorption.
Secure storage: Fertilizers are stored away from children, pets, and water sources.
Controlled application: We use targeted spraying or granular distribution to avoid overapplication or drift.
Post-treatment guidance: We advise homeowners to wait 24–48 hours before allowing kids and pets on the treated area.

Every step is designed with Calgary families in mind.

Common Questions About Kelp Fertilizer Safety

“Can my dog get sick from kelp fertilizer?”

Unlikely. Kelp has minimal odor and isn’t attractive to pets. That said, it’s still best to avoid ingestion, our team ensures no granules are left exposed.

“How long should I keep my kids off the lawn?”

With kelp fertilizer, 24–48 hours is generally sufficient. We recommend waiting until the treated area is dry.

“Is kelp fertilizer as effective as synthetic?”

Yes, for long-term tree and soil health. While synthetic fertilizers may act faster, kelp builds sustainable growth over time without harsh chemical impacts.
