Lawn Fertilization - Pet Safety Tips

We love our pets! We want them to be able to fully enjoy the grassy space of the outdoors. But at times our Tulsa lawn’s fertilization and weed control needs may require the use chemicals that if ingested can  have serious effects on dogs and cats.

“While small ingestions of fertilizer may only result in mild stomach upset, larger ingestions can result in severe poisoning from the iron, nitrogen, and other chemicals,” The Pet Poison Helpline noted.


It’s very easy for pets to pick up fertilizer on their paws, or body, by rolling around in a lawn, and thereafter quickly ingest the weed control herbicide or fertilizer.

Dr. Petra Volmer, a veterinarian and toxicologist at the University of Illinois, College of Veterinary Medicine in Urbana said in an article about pets and safety around fertilizers stated, “If you find your pet rolling or walking in a recently sprayed area or spray him by accident, immediately wash the substance off with a mild dish soap, such as Dawn, and contact a veterinarian.”

Dr. Volmer  also noted that insecticides like those used in the garden for roses and molluscicides for snails, , are often more toxic to pets than herbicides or fertilizers so it’s good for homeowners to be especially careful when using these around animals.

What can you do to protect your pets when you’re fertilizer or weed control treatment to your Tulsa lawn?

It’s always best to follow the instructions on the manufacturer’s label exactly in how much to put down and when to permit access to lawn again. Applying too much fertilizer may cause the grass to retain the fertilizer residue for an extended period of time.

Carrie Gustavson with the University of Illinois, College of Veterinary Medicine stated “…make sure a treated lawn is completely dry after waiting the maximum period recommended on the label. To be extra safe, consider watering down the lawn after application and letting it dry before allowing pets into the area.”

Liquid fertilizers, may be harder to see on the lawn, and to know if they've been absorbed into the soil. Often water will be used along with a liquid fertilizer to help it be absorbed into the soil. You’ll need to keep pets off the lawn until the grass is visibly dry after being watered, an article in the SFGate Home Guide noted.

With granular fertilizers broadcasted across the lawn it can more easily be noticed that the fertilizer pellets have dissolved and been absorbed into the soil after a watering of the lawn. Generally, you can allow your pets back onto the lawn 24 hours from when you last saw any granules on the grass blades.

You may want to wait at least 48 hours after the fertilizer application before you allow your pets back onto the lawn, to be on the safe side.

“Consulting a professional landscaper for custom fertilizing instructions is the best way to stay safe if you are unsure of the application amount,” the SFGate Home Guide noted.
