When nitrogen is off-limits

Some regions restrict nitrogen fertilizers during summer to protect waterways. Green Out lets you keep feeding without breaking the rules. The 0-0-5 formula delivers potassium, chelated iron for deep green color, seaweed for stress tolerance, and micronutrients including boron, manganese, and zinc. The sweet bonus treat? Molasses to feed soil microbes.

No nitrogen. No phosphorus. All fertilizer blackout compliant nutrients.

FAQ

What is Green Out and when do I use it?

Green Out is a nitrogen-free fertilizer (0-0-5) for regions with fertilizer blackout restrictions. It delivers potassium, iron, seaweed, and micronutrients to maintain lawn color and health when nitrogen application is restricted. Use it during summer blackout periods in Florida, Maryland, and other regulated areas.

How long should I wait before watering after applying Green Out?

Wait at least 3-4 hours for the product to dry on grass blades. If you can wait 24 hours, even better. The chelated iron needs time to absorb. Watering too soon washes it off before it can work.

Can I overseed after using Green Out?

Yes. Green Out won’t harm ungerminated seed. Seed before application or wait at least a day after application to overseed, or apply Green Out after seeds have germinated and been mowed twice. It won't interfere with seed establishment and will give them nutrients to grow deeper.

I live in Florida and there are fertilizer restrictions in my county. Does Sunday ship compliant products?

Yes. Sunday's lawn plans account for local fertilizer restrictions. Green Out is specifically formulated with zero nitrogen and zero phosphorus to comply with blackout periods. Check your plan dashboard for timing specific to your location.
