Just finished using this, and thinking about the review as I went along. I'm giving it 5 stars, because it worked as advertised, but I have a few caveats. First, as mentioned, I just finished using it, and it looks great right now, but if it fades immediately, I would downgrade this. As an aside, the container was smaller than I thought. It's one quart, not a gallon (and says that if you pay attention), but it covered what I needed covered. Obviously this does not replace mulch, which has many benefits, like weed control, water retention, soil cultivation. Also, you are just spraying the top side, so if you have lots of kids or animals or other things that are turning over the mulch, it will look faded quickly. I put on mulch about every other year. I order 5 yards, which seems to be enough to make about 100 wheelbarrow trips on a hot Saturday, and is a generally unpleasant job. Since I just did this last year, and have more than enough mulch down right now, but just wanted it to look better, I thought I would give this a shot. I took a rake and fist turned over the mulch for a bit, and pulled any big weeds. I hosed down areas that I didn't want to get colored, like walls, sidewalks, and plants. I used a new pump sprayer - spring for a new one and then just dedicate it to this job. You are going to be pumping gallons of dye through this thing, and it's never going to be the same, so just use it for this task. They're cheap. As a general note, you are essentially getting 32 ounces worth of dye, and should take obvious precautions, like wearing clothes that can get stains, and gloves, and keep the hose handy for any drips that you want to quickly spray. I only got one big drip on the concrete, but the hose quickly removed it. I went over everything twice, since it will absorb, and like any painting job (which this essentially is) the first coat never looks great. Good marketing that they have 'enviro' in the name, BTW, since it will feel anything but positive for the enviro as you stand in the middle of your yard and paint your mulch, but at least you can tell any noisy neighbors how the product has 'enviro' in the name. So, my mulch looks great now- it has that sharp black and green contrast between the mulch and the plants again. I also have some left over, which will come in handy to use a few days before we have a party or something. If you don't have a day and hundreds of dollars to dedicate to freshening up the mulch beds this year, but you do have an hour or so after work and $25 bucks, this is a good way to go.
