Your lawn can handle California drought. Really.
California Drought Defense Lawn Treatment is a 0-0-1 NPK liquid fertilizer that helps soil hold water instead of running off. A surfactant tackles dry spots and brown patches. Seaweed, potassium, and humic acid handle the heat. No pesticides, no NPEs. Pair with Lawn Aid or a custom plan.
What makes California Drought Defense Lawn Treatment different
- 0-0-1 NPK formula built for drought resilience
- Surfactant helps soil absorb water, not waste it
- Hooks up to your hose, done in 15 minutes
- Works on all common grass types
- Can reduce water usage by up to 20%
- Made without pesticides or harmful NPEs
Ingredients
Wetting agent (surfactant): Helps water penetrate soil instead of pooling on top or running off. This is especially useful for soil that repels water, a common problem in California lawns during drought.
Seaweed and potassium: Helps your grass tolerate heat and recover from stress. Think of it as giving your lawn the tools to stay green when temperatures spike.
Humic acid: Improves how well roots absorb nutrients from the soil. Healthier roots mean a lawn that holds up better through dry conditions.
How to use
Apply before drought conditions hit. Best in early morning or late evening when your lawn is well hydrated.
- Connect the sprayer. Attach the included hose-end sprayer to the pouch and hook it up to your garden hose.
- Spray evenly across your lawn. One pouch covers 1,000 to 2,500 sq ft. Two pouches cover 2,500 to 5,000 sq ft. All three cover up to 7,500 sq ft. Takes about 10 to 15 minutes per pouch.
- Water thoroughly after applying. Give your lawn a good soak right after you finish. Once the product dries, you're good to go back on the grass.
- Reapply every 4 weeks from spring through fall. You can apply up to 8 times per year. Let the liquid fertilizer dry completely before applying other Sunday products.

Questions & answers
5 questions
Question: Will drought defense help green my lawn or do I need another fertilizer?
Sunday
Drought Defense is a preventative product designed to help grass survive drought stress through better water distribution in soil. It's not meant to green up your lawn since it has no nitrogen (it's 0-0-1). For actually greening your lawn, you'd want something with more nitrogen like Grass Powerhouse, Green Machine, or Super S, which have higher nitrogen content for that vibrant green color. You could use Drought Defense alongside a greening fertilizer in late spring/early summer to prepare your grass for summer stress while building that color at the same time
Question: On my plan I have the lawn aid heat stress prevention treatment to be applied in the first couple of weeks of June. Can I add the Drought Defense product to use in August when we have almost zero rainfall and waves of heat up to 90/100? Or will it be too much?
Jeff McConathy
That won't be too much! These pouches don't include any nitrogen, so we have a bit more flexibility with incorporating them relative to some of our other pouches. Lawn Aid from is best used to help encourage deep root growth/better heat resilience, and Drought Defense will help to improve water retention and Drought Defense will help with water retention and reduce water use. We generally recommend using these pouches every 4-6 weeks (if needed) during the summer months, so aiming for Lawn Aid in early June and then Drought Defense in early/mid July would be perfect.
Question: Is the new Drought Defense a replacement for the Water Focus product which I no longer see on your
Louisa D.
Water Focus is no longer available for individual purchase. Drought Defense is an innovative surfactant formula to minimize drought stress and reduce water use in lawns.
Question: Your add says this product is 30% off, no code needed but that is not reflected at check out.
Louisa D.
We are currently running a 30% off promotion for 4th of July. This offer is valid until July 7, 2024.
Question: What is the difference between the drought defense lawn treatment and the lawn aid heat stress prevention treatment. They seem to be almost the same.
Louisa D.
Great question! Drought Defense is designed to be used in arid climates or regions currently experiencing periods of low rainfall, helping maintain a healthy, green lawn. Lawn Aid, on the other hand, is designed as a preventative before arid or low rainfall conditions exist.
