32oz 4X Green Spray Dye - Makes 128 Gallons of Concentrated Spray Pattern Indicator Dye, Ideal Fertilizer Marking, Lawn Turf Mark and Marker, Mark Where You've Sprayed with Green Color Indicator

Definitely a strong green dye. I sprayed it on my dead winter grass and it made my lawn look awesome. However, I had a neighbor get really ticked off when she allowed her white Maltese to walk through my yard to go potty and ended up with dyed deep green paws lol She was not happy and it wasn’t my fault that with the morning dew she allowed her dog on to my lawn while walking her, and it stained her white fur. She demanded that when I spray it I put a sign out so I will post a sign from now on, but maybe it will make her think twice before she lets her dog go potty in my lawn in the future lol

I use it to mark where I've been when using herbicides and liquid fertilizer. Rain and/or irrigation rinses off any areas where you might have been little sloppy so no need to worry about driveways, fences, etc.

Arizona rock and cactus yards, I use 1 tsp per gallon of spray. Lasts about 10 days in the Sun.

So right off the bat this dye doesn't stain the cement permanenantly. And it doesn't last long on your lawn either. So if you are that type of person that likes to paint your lawn when applying fertilizers, or other liquid lawn care (and want that painted green look to last), this may not be for you.

Too messy. It dyed the grass green but it lasted only a few days. When it rained the dye went down to the sidewalk. After 4-5 rains ; the sidewalk stains disappeared.

I bought green thinking it’d hide the ugly spot in my yard after I sprayed. It did that well but the mixing ratio has to be pretty high or it’s difficult to see where you sprayed. I think that using blue would make it easier to differentiate what’s been sprayed and what hasn’t.

The green was really tough to see on the grass, kind of defeated the purpose I was using it for.

Works great , i like the color and it is very concentrated

Pretty good stuff, I mixed it a little stronger than recommended, I was using it for dye marking so I knew where I'd sprayed the more expensive product I'm using (and it doubled as a way of seeing how contaminated I got) and well... it works. It was a little harder to see the difference when I was spraying at dusk after work but it's very obvious in the sunlight. Left side of the photo is treated grass, right side is not (I'm not spending on the council property lol)
