Best moss killer Thrifter 2021
If you have moss, then your lawn has problems. It might not seem like it at first since moss is short and green just like your grass, but that moss is filling in all the gaps your grass hasn't been able to fill in yet. Your lawn will suffocate and stop growing if the moss is allowed to expand unchecked. While moss growth can often indicate deeper problems like too much shade, compacted soil, and bad drainage, the first step to fixing those problems is getting the moss under control. We have the best ways to kill and control moss on Amazon.

Go Green!
Moss is insidious because it blends in to your grass, and if you're going for a curated, well-manicured area you might not even notice much of a difference at first. However, while moss may not be directly harmful at first, it tends to grow faster than your grass and spread into all the gaps your grass hasn't filled in yet. If you've got a new lawn or a damaged lawn that needs to grow, moss will only hinder it. Something simple like Scotts MossEx is perfect for getting the moss under control and letting your lawn grow where it needs to grow. You can also stock up on spray bottles like the BioAdvanced spray that work with your garden hose, letting you mix the formula with water.
