Can I Use Preen On My Lawn?

Yes, you can use Preen on your lawn to help maintain it and keep it healthy. It is safe for children and pets to be around when you are applying this natural product. Preen is a great way to keep your lawn looking vibrant and beautiful throughout the seasons. 

The best time to apply Preen is in the springtime when temperatures begin warming up after winter so that plants can absorb more nutrients from the soil which will help them grow strong roots deep into their beds so they can better withstand being outdoors during colder months as well as during hot summers because there’s less water loss through transpiration with stronger roots that reach deeper down into their beds’ moisture levels!

A pitchfork can be a useful alternative to a lawn aerator machine. In fact, using a pitchfork to aerate your lawn can work just as well, and is a more budget-friendly option. Learn more about aerating your lawn with a pitchfork to start saving money on lawn maintenance.

Why Did I Get Clumps After Using Preen?

Often when people apply Preen to their lawns they notice clumping in the grass. This is normal and happens because of a natural humectant (a substance that attracts moisture) found in Preen that can cause the soil to retain water more than usual. 

In order to get rid of clumping, it’s important not to use too much product or overwater your lawn. Instead, slowly sprinkle more Preen over the affected area until you see results; this should take about 3-5 days for most users.
