Revive your Lawn with a Core Aerator
If you’ve been trying to figure out how to get your lawn looking lush and green, but haven’t wanted to shell out tons of money to a landscaper, then the answer could be getting your hands on a core aerator. Aeration with a core aerator only needs to be done once a year and usually only takes a weekend to complete; however, the results can be staggering and are well worth the effort.
For both thatch buildup and compacted soil, the key is to create space that will allow roots to grow and will allow nutrients, water and air to better reach the roots of your grass. Lawn aeration essentially punches thousands of small holes in your lawn, thus creating that needed space.
To have effective aeration, you need to use the right aerator. You can find many different types of spike aerators for a pretty reasonable price; however, almost all are a waste of money. Spike aerators use solid tines to punch holes, and, rather than removing soil, the tines just displace it. This can actually further compact the soil, making your problem worse. Core aerators, on the other hand, use hallowed tines to actually remove chunks of soil, creating more space for the roots to stretch out. You can find both manual and power aerators, though unless you only plan to aerate a small patch of lawn, power aeration is the only way to go.
Power aerators typically look like large, heavy-duty lawn-mowers and have a revolving cylinder surrounded by tiny spoons that remove the chunks of soil. They are typically gas-powered and can be rented from most tool rental stores or big home repair chains for under $100 a day. They usually weigh about 200 pounds, so you will need either a large pickup truck or trailer to transport it, or you will need to speak to someone about delivery and pickup, usually for an extra charge.
Lackluster grass and patchy spots are often the result
of compacted soil or a buildup of thatch. Regardless of the quality of
your soil, it can become compacted over time from steady foot traffic,
riding lawn mowers, or even heavy rain; if your soil has a high clay
content, then compaction is even more likely. Roots need space to grow
and space to allow in nutrients, water and oxygen. When the soil
becomes compacted, there is no room for growth or access of essential
elements. Over time, your lawn will become patchy, then limp, and then
eventually, could die out altogether.
Thatch is another
issue that affects almost all lawns if not addressed regularly. You can
usually tell that you have a thatch problem if, when you walk on your
lawn, it feels spongy and soft. Thatch is a collection of decomposing
plant matter that gathers between the tops of the grass and the surface
of the soil. Once thatch gets thicker than about ¼ inch, it begins to
strangle the grass and keeps water and nutrients from penetrating the
soil’s surface and reaching the grass’ roots. Heavy thatch buildup can
be the result of soil with too much alkaline, too much overnight
watering, drought, or overuse of high nitrogen fertilizer. To
determine how much thatch has built up, cut out a section of your lawn
and lift up the edge. You will quickly be able to see the thatch
buildup in the cross-section. If it is thicker than ¼ inch, it is time
to aerate.
When done once a year, aeration will reverse damage caused by thatch or heavy traffic. The tool is easy to use and you can usually aerate 5,000 square feet of lawn in about 3 hours. With regular aeration, your lawn can soon be the envy of the neighborhood.
