In a recent column, I discussed some of the autumnal chores that gardeners and landscapers should be addressing now to ensure an easier and more productive spring next year. That column included some brief lawn tips. But that wasn’t enough!
This morning, as I sipped my first cup of coffee, I looked out the kitchen window and saw in the dawn’s early light that my lawn was still there, to paraphrase a well-known anthem. As I watched a gust of wind chase a flurry of leaves around in circles, it struck me that, for most of us, the major part of our landscape consists of ... grass.
However, it’s quite easy to take the lawn for granted while we concentrate on our shrubs and trees. We just mow it every so often and turn our attention to the more interesting flora.
A lush, green lawn can make even a modest home seem a little grander. On the other hand, a scrubby, thatched lawn seems to convey a much more negative impression.
So let’s take a look at your lawn and see how we can nudge it from scrubby to lush.
Thatch “Thatch” is just another name for that dead grass that looks like a smaller version of straw and is tangled in dry masses around the green (live) grass. It gives your lawn a grey, dead look, and prevents much of what you might spread on your lawn – such as grass seed or fertilizer – from reaching the soil.
So you need to “dethatch” your lawn. The most effective way is to give it a vigorous raking. Most of the live grass will stay put, anchored in the soil by its roots. But the thatch will pull away in the tines of the rake. You might be surprised by the high volume of thatch that you harvest this way!
Here’s a tip I picked up from David Beaulieu at www.landscaping.about.com that will get two jobs done at once. While you’re raking up the fallen leaves, be sure to rake deeply instead of simply skimming the surface of your lawn. This way you’re gathering both leaves and thatch.
Those useful leaves... Instead of burning your fallen leaves or bagging them up like garbage, put them to use around your landscape! First decide if you want to use them as mulch or as compost.
You might be wondering about the difference between mulch and compost, as the two are frequently confused. Essentially, mulch forms a layer of protection around plants, keeping moisture in and keeping extreme heat or cold out. Compost is mixed with soil to provide nutrients to your plants. Put your leaves, grass clippings and kitchen scraps into a large covered bin and turn regularly to aid the composting process. You can find out more by visiting www.howtocompost.org.
Mulches can reduce moisture loss by 10 to 25 percent, and this can be important in winter months when frost-hardened soil can make it hard for plants to absorb the essential moisture. When mulching trees, cover as much of the root zone as possible, extending out at least 3 to 6 feet from the base. To prevent bark decay, pull out the mulch about two inches from the base of the trunk.
As a rule of thumb, to cover a 100 square foot area with mulch to a depth of three inches, you’ll need one cubic yard of organic material such as leaves, pine straw and pine bark nuggets.
In the case of both compost and mulch, you’ll aid the effectiveness if the leaves are shredded, and a lawnmower is the simplest way to achieve this.
