Q&A
- When is it safe to let my pets on the lawn
- Generally, our lawn fertilizer and lawn care products are safe when used according to the product label. Here are some important guidelines to keep in mind: Fertilizer: It should be watered in before allowing people and pets onto the lawn. **** Killer: Ensure it is dry (approximately 30 minutes) before giving access to the lawn. Fungicides and Insecticides: These should also be watered in first.
