What makes Grass Machine Liquid Lawn Fertilizer different

- Pesticide-free, made with plant-based ingredients
- Covers up to 3,000 sq ft per pouch
Ingredients
Nitrogen (15%): Fills in and thickens your grass by driving leaf and blade growth across your whole lawn.
Iron: Delivers that deep, rich green color you notice from the street. Your neighbors will notice it too.
Potassium (3%): Helps your lawn hold onto water and bounce back from heat, foot traffic, and dry stretches.
Seaweed: Supports greening and long-term turf resilience. Think of it as a multivitamin for your lawn.
How to use
Apply early morning or evening when temperatures are between 50 and 85 degrees F. Avoid using on drought-stressed or heat-stressed lawns.
- Connect the hose-end sprayer to your garden hose and attach the 42 fl oz pouch.
- Turn on the water and walk your yard, applying evenly until the pouch is empty. This takes about 10 to 15 minutes.
- Once the liquid has dried on the grass, you're good to get back on your lawn.
- Reapply every 4 to 6 weeks from spring through fall for steady feeding all season.
- Keep the sprayer for future use. Let liquid fertilizer dry completely before applying other products like weed control or grass seed.

Great Product
I've had great success with this product! We put down turf in early spring and it kinda died out by next spring. Used the product and within a few weeks after it started to warm the grass came back!!

Was this review helpful?Good but need hose connector
I bought the set from Costco. The first one worked great but I didn't know that there was only one hose connector which I accidentally threw in the trash and now I don't have a hose connector and 3 bottles that I cannot use
Was this review helpful?Ugh 😣
Dropped the pouch on the grass while using. Picked it up and continued on … did not realize one of the pouch seams busted open and it was leaking … lost produce and when I was crossing over my driveway, a new driveway on a new home by the way, the product stained my driveway and I can’t get the stains out.

Hello Paul, we are truly sorry to hear about your experience with our pouch. If you prefer a more natural approach, lemon juice or white vinegar may help lighten the stain depending on how much product was spilled, how long it sat, and whether the concrete is sealed. Just be careful to prevent runoff into the lawn, since both can cause some grass burn if they reach turf in concentrated amounts. For tougher stains, a dedicated concrete cleaner may be more effective. The same caution applies here. Avoid allowing any cleaning solution to run into nearby grass. Keep in mind that both natural remedies and commercial cleaners can affect the concrete seal. It may be worth checking with your installer to see what they recommend before applying any stain removal treatment.
