Instructions:

If using other Sunday products, let liquid fertilizers dry completely before applying anything else to the lawn.
Helpful Tips from Lawn Advisors:
When is the best time to apply?
The best time of year to apply is before peak summer heat, typically in April, May or June. Lawn Aid is designed to prepare your lawn for heat stress and needs time to be absorbed before your lawn is exposed to extreme summer heat.
Can I apply more than once a season?
Yes! You can apply one pouch to actively growing grass every 4 to 6 weeks. Do not exceed 8 applications per growing season.
Can I use Lawn Aid with my custom nutrients?
Yes! Lawn Aid can be used in combination with your custom lawn plan. No waiting period is required but we recommend waiting until the first application is dry. This may take between 4 and 24 hours depending on your climate.
When is it safe for people and pets to go on my lawn after applying?
Our ingredients break down quickly and don’t persist in the environment. After our products dry, you can get back to playing outside right away!
Are there any US states where this is not approved for use?
This product is approved for use in all states.
