Core Aerations for a Greener Grass and Healthier Turf

It is now fall, or it is quickly approaching, and as the weather cools your lawn is prime to recover from the stressful summer months. July and August are traumatic for the lawn by providing plenty of heat and sunlight, and very little water. This environment will push your lawn into dormancy to protect itself. And any weak parts in the lawn will more than likely die off, or become overwhelmed with weeds during this time. As the last heat wave passes by, it is a great time to handle these areas and to aerate the lawn to help strengthen it for the following summer.

A core aeration is one of the greatest things you can do for you lawn. This is a process that will take cork sized plugs out of the ground. It is a natural and organic way to care for your lawn, and will create a greater environment for the roots and grass to grow. It is recommended to do in the fall when the weeds are dying off and the lawn is now growing again as the weather provides plenty of moisture. Let’s go over the benefits of the aeration, and some ways to do it.

  • Turns over and loosens soil
  • Reduces compaction
  • Increases water and nutrient intake
  • Reduces thatch layer
  • Provides greater tolerance to stress

The best method to use in my opinion, is to use a core aerator and go over every squareImage result for aerating inch of the lawn. You could go in two different directions to further the impact, but doing the lawn once is fine. The machine should be in good shape with fresh tines to make sure you take full plugs out. If you have the option, do the lawn when it is a little wet.  And also make sure the lawn is cut prior to aerating. You can lower the mower deck in the fall to shorten the grass. This will increase the depth of the plugs and also let the plugs sit harmlessly on the top of the grass for a week or two while they break back down. Great, great annual practice to get into.

Another option is to use the tow behind aerator. This attachment hooks to the back of your tractor and also takes out plugs. This type of aerator is much light and does not take Image result for aeratingdeep lugs. If this is your method, weigh down the aerator with concrete blocks or sand bags or something. The tractor setup will probably miss large chunks of the lawn, mainly the corners. Or you can continually try to back the thing up.

Spike aerations are also a method used. There are a variety of ways to do this, from quad tines or spike machines, or just strapping shoes to your feet that have long spikes on them and walk around.

It is quite common on golf courses, especially greens and fairways.

You can purchase a used tow behind attachment for your tractor for cheap money. It is only needed once a year (typically don’t aerate in the spring –> opens the door for crabgrass), and even if done twice a year or if friends and family borrow it, it should last quite a long time. It is not the most effective method, but it works well and will help your lawn. We recommend to stay away from spike aerations for your personal lawn as the impact of the process isn’t quite the same.

A great way to go about aerating the lawn is to talk to your neighbors and plan a day where you pitch in and rent a machine. Ideally, the lawn should be a little bit wet, but the timing may be tough, so no biggie. It should cost less than $100 for a day and will be able to handle 10,000 sqft in less than an hour. It will take a few passes to get used to it, but don’t worry about handling one. Be careful and take your time.

One warning – the aerator, of course, digs in the ground to take the plugs out. Mark all irrigation heads and boxes, and any wires that are close to the surface. The invisible dog fence will absolutely get hit, so mark it before and and give it a wide birth.

Summer weeds

During the dog days of summer, a different kind of weed presents itself.  These weeds strive with very little water and nutrients and love the heat.  I’m talking about crabgrass, spurge and sedge grass to name a few.  There are some pictures below to help you identify these three.

Each of these you will find without much problem through the month of July and August. As the weather maintains a high temperature and humidity, and the rain is sparse, the grass weakens and these three will take over.

The best way to handle these weeds is to make a mental note of them and try to fill those areas in with fresh seed when the weather cools off.  As soon as the last heat wave is past us, than scratch those areas up and put down a good quality seed that will thrive in your particular environment (shade, sun or a mix).  It is important to keep fresh seed wet for a couple weeks until the roots start to take and there begins to be germination.  This is a critical time for fresh seed and you must take care of them or else you’ll have to start over.

There are herbicides for these three, and they do work.  But with the grass in a weakened state, it may do harm to the lawn.  Use your judgement or speak with a pro to decide if it’s worth spraying them or not.  If you have a good healthy lawn, than it is a good idea to spray.  Another way to put that is if the weeds are mixed in with alot of grass, than go ahead.  If the area is mainly weeds and not alot of grass mixed in, I wouldn’t bother with the spray.  It will turn the area into a discolored mess and become more of an eyesore.

These weeds will go away naturally when it cools off.  You must take some seeding action to prevent the same problem in the future though.  So wait until the weather cools off and there are wetter nights to put some seed down.  Try to fill in those areas with healthy grass and allow the thriving lawn to choke out these summer weeds.  Thanks for checking in,
