When to apply Drought Defense
Start applying Sunday's Drought Defense lawn treatment when the grass is actively growing in early spring, typically from May to June, and continue through late summer into fall*.
*You can apply Sunday Drought Defense up to 8 times throughout the season
Sunday Tip:
Already experiencing drought? Drought Defense can also be applied as a post-drought lawn recovery treatment to help repair and rehydrate your lawn!
How to apply Drought Defense
Hydrate your lawn
Make sure your lawn is adequately hydrated before applying Drought Defense. If natural rainfall has occurred, that's enough. Otherwise, you can water the day before or up to 2 hours before applying the pouch.
Prep the pouch
Shake the pouch thoroughly. Remove the cap and attach the hose-end sprayer nozzle securely.
Attach your hose
Hook up your hose to the hose-end sprayer nozzle. Turn on the water and open the valve to spray when ready.
Spray it on
Drought Defense can be applied as a complete lawn preventive treatment or spot treatment application for concentrated dry spots in lawns.
For full lawn application: Spray Drought Defense evenly across your lawn. Aim for a light, even coat of nutrients across the entire coverage area, doubling back for an additional coat if needed. A full pouch should take about 10–15 minutes.
For dry spot application: Spray Drought Defense directly onto dry patches in the lawn. Aim for about 4-6 seconds per spot.
For post-drought recovery: Apply to an entire lawn or dry spots according to the instructions above.
Sunday Tip:
If you have a large lawn or only want to treat part of your lawn, focus on dry spots that are more prone to stress due to low moisture, full sunlight or high foot traffic.
Let your lawn dry
Water your lawn thoroughly post-application to ensure the product reaches the soil for the best results.
Allow your lawn to dry thoroughly before returning to the lawn. Save any leftover product and your sprayer nozzle for future use.
How to apply with a Sunday custom lawn plan
Granular fertilizer plans
Wait 7+ days between applying granular fertilizer and Drought Defense to your lawn. If it's been 7 days or more, use it when the grass is growing and isn't stressed.
Liquid fertilizer plans
Allow at least one week between liquid nutrient applications, before or after your first application date. Apply anytime grass is growing and not stressed.
Sunday Tip:
Apply your Sunday fertilizer first, then follow with Drought Defense 7+ days later. This sequence optimizes both nutrient uptake and water efficiency.

Sunday Drought Defense FAQs
What is Dorught Defense? How does Drought Defense work?
Drought Defense is a liquid lawn treatment formulated to enhance drought resilience in lawns. Its advanced surfactant technology minimizes drought stress, improves how your lawn absorbs water, and can help reduce lawn water use by 20%.
The advanced surfactant technology in Drought Defense reduces the surface tension of water molecules, allowing moisture to penetrate more efficiently into soil rather than running off. It also helps distribute water more evenly throughout the root zone while strengthening grass against dry conditions.
How to care for lawns during drought
For maximum drought resilience, pair Drought Defense with these complementary strategies:
Irrigation system optimization (May is ideal)
- Good: Check for and repair broken sprinkler heads
- Better: Upgrade to water-efficient rotating sprinkler heads
- Best: Install a smart irrigation controller that adjusts to weather conditions
Additional lawn care practices
- Raise mowing height to 3-4 inches during summer months
- Audit watering schedule to avoid inefficient timing or excessive frequency
- Consider transitioning to drought-tolerant A-list certified grass varieties like fescues (takes 1-2 years to establish)
Can I apply Drought Defense during water restrictions?
Drought Defense is especially valuable during water restrictions as it maximizes the efficiency of limited watering sessions and is formulated for zero burn risk.
How do I use Drought Defense with other Sunday products?
Drought Defense is made to work with Sunday fertilizers, lawn plans, and other Sunday lawn products.
When applying with other Sunday products, let Drought Defense dry entirely before applying anything else to the lawn. For best results, use in combination with fertilizer, weed control, and grass seed. This will help you feed properly, reduce weeds, and introduce better grasses to your lawn.
How soon can I see results after applying Drought Defense?
You may notice improved water absorption immediately after the first watering following application. Full drought resilience benefits typically develop within 1-2 months of application as the product applications increase resiliency.
How and where do I store products?
Store this product sitting upright with the cap closed tightly. Do not store in excessive heat or freezing temperatures. Pouches can be reused but shake well before each use for optimal performance.
