When to apply liquid lawn fertilizer
Apply liquid lawn fertilizer according to your custom lawn plan.
If you don't have a custom plan, start fertilizing in spring when daily temps hold between 50-85° F.
For best results apply at the right temperature threshold for your grass type:
- Cool-season grasses require temperatures above 50-59° F.
- Warm-season grasses need temps above 60-69° F.
Apply every 4-6 weeks when grass is actively growing.

How to apply liquid lawn fertilizer
Prep the pouch
Shake the pouch. Then remove the cap and attach the sprayer nozzle.
Attach your hose
Hook up your hose to the sprayer nozzle. Then turn on the water and open the valve to spray.
Spray it on
For best results, apply in the early morning or evening.
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.
Save for later
Save your sprayer nozzle for next time.
Let it dry
You can get back on your lawn as soon as it dries. Check your My Plan account page to see your next application date.

Liquid lawn fertilizer FAQs
What if I miss an application?
Don't worry if you miss an application! You can apply liquid fertilizer after your application date. Just be sure to wait at least a week between applications.
How do I use this with other Sunday products?
Sunday liquid fertilizers are made to work with other Sunday fertilizers, lawn treatments, custom plans, and other Sunday lawn products. When applying with other Sunday products, let liquid fertilizers dry completely 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.
When should I stop fertilizing?
Stop fertilizing in the fall—sometime between the end of September and mid-October when temperatures cool down and lawns are no longer actively growing.
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.
