Don't let moss ruin the look of your lawn. This is your 2-in-1 solution to tackle moss and give your lawn a good feeding. It's designed to kill moss, not your grass, while helping your lawn grow thick and green.
Moss can be a real downer, showing up in those shady, damp spots and making your lawn look less than its best. But you don't have to live with it. Scotts Turf Builder with Moss Control is your one-two punch for a beautiful, moss-free lawn. It's a 2-in-1 formula that does exactly what it says: it kills the moss you have now and feeds your lawn to help it grow in thick. A thicker lawn is your best defense, naturally crowding out space where new moss could grow. It's a simple, effective way to get back to the lawn you love.

You don't need to water this product in. In fact, it works best when you apply it to a moist lawn and then let it do its thing.
Fix the Root Cause: Moss loves shade, damp soil, and poor drainage. Try trimming some tree branches to let more light in, or aerating your lawn to improve drainage. This will help keep moss from coming back.
Got some left over? No problem. Just fold the top of the bag down, secure it, and store it in a cool, dry place like your garage or shed, safely away from kids and pets.
You might see some temporary darkening of the grass blades, but don't worry—it's normal and will disappear after the next time you mow. The moss, on the other hand, will turn black and die.
Once the moss has turned black, which can take a couple of weeks, it will eventually disappear. If you want to speed up the process, once the moss turns black, just use a rake to remove it.
That's the million-dollar question. Moss thrives in shady, damp areas. The best long-term solution is to change those conditions. Trimming trees to let in more sunlight, improving soil drainage, and keeping your lawn fed and thick are all great ways to make your yard less moss-friendly.
