You know the feel of a great lawn under your bare feet, and you work hard to grow that thick carpet. But when the turf feels too spongy as you walk on it, or water runs right off the surface, it's time to get the thatch out.

Step1

Check for excessive thatch - that's the thick mat of clippings, cuttings and stems that builds up between the green blades and the soil surface. Get down on your knees and part the grass with your hands to see if it's built up to more than an inch.

Step2

Understand how de-thatching works: When air, water and light cannot reach the soil surface any longer because of thick thatch, you have to rip it out. The lawn looks rough for a while, but soon you'll see healthy new grass shoots taking off.

Step3

Start by really raking the grass with a stiff-tined garden rake or a de-thatching rake. Work up a sweat - sink the tines into the thatch and pull out as much as you can without pulling up the grass.

Step4

Can't see the ground even after vigorous raking? Try using a de-thatching blade if your mower has one, or rent a de-thatcher from a reliable dealer who can brief you on its safe operation.

Step5

Water the lawn the day before de-thatching only if it's very dry. Begin running the de-thatcher at the farthest point from your home so you can master it before hitting the high-traffic areas.

Step6

Watch what you're doing - keep the de-thatching blades on target to cut through the debris without scraping the soil surface. Run the machine over each swath of lawn only once.

Step7

Use a leaf rake to clean up the messy piles of thatch you've removed. Recycle all of it in your compost pile.

Tips & Warnings

Make annual raking a part of your lawn care routine to prevent thatch buildup.
Fertilize once after de-thatching with a slow-release lawn food formula.
Keep foot (and paw) traffic off the area for one month if possible.
Use a power tool only if you understand its operating and safety features.
Always wear long pants, closed-toe shoes and safety glasses when operating power equipment.
