Common Lawn Care Mistakes

By October 4, 2019Blog

Whether you are in Calgary or Red Deer, Alix or Airdrie, Olds or Okotoks, when it comes to caring for your lawn, homeowners are prone to repeating the same mistakes. Here are a few things NOT to do:

1.Scalping the lawn

If you think you are doing your lawn a favor by giving it a “good cut” to start the season, you are wrong! Mowing grass too short can put it into shock and is very harmful to the plant. Similar to the leaves on a tree, grass plants absorb sunshine through their leaves and make food (glucose) through photosynthesis. They need their leaves to absorb sunshine to make glucose to eat and grow.

Scalping your lawn stresses the grass, making it less healthy and more prone to disease, and makes space for weed growth.

2. Over watering

When it comes to watering, over watering can be just as destructive as watering too little.

It is better to water deeply, less often, then to water a little bit frequently.

If you water too frequently, the grass will fail to develop deep roots because there’s no need for it to reach deep down into the soil to find moisture. Watering the correct amount allows the grass to grow deep roots, creating a lawn that’s much stronger, healthier and better equipped to survive drought conditions.

As a general rule, most lawns require about an inch of water per week, but that varies widely based on weather, soil conditions, and grass species.

Over watering discourages the grass plant from developing a deep root system.

3. Mowing the grass too short

As we shared under “Scalping Your Lawn”, you are actually harming your grass by cutting it too short – not doing it a favour.  Cutting your grass too short:

  • makes the plant less healthy and more prone to disease
  • makes room for weeds to sneak in and grow, encouraging weed growth, as there is now less competition for the same space

We recommend cutting your grass to a height of 2-1/2″ to 3″. Cutting it at this height will encourage the grass to develop a deeper root system to support the longer blades, require less water, promote growth, prevent weeds and discourage insect pests. Plus never cut off more than 1/3 of the grass blade at any one time.

Keeping your grass cut at a short height (below 2-1/2″)  makes it less healthy, more prone to disease and makes space for weed growth.

4. Dull mower blades

Mowing with dull blades will tear the glass blade and not leave a clean cut. A  torn or ripped blade of grass is also more prone to disease and insect damage. We recommend to check your lawnmower blades at the start of the season, and sharpen if necessary. Plus make sure you periodically check the blades throughout the lawn mowing season to make sure they are still sharp.

5. Misapplication of Fertilizer

At Green Oasis we have been mixing and applying lawn fertilizers for over 25 years, so we know how complicated it can be.

While most homeowners know it’s important to fertilize their lawn, few know how to do it correctly. Applying the wrong fertilizer or applying too much fertilizer can do more harm than good. And the correct fertilizer can be ineffective if applied too sparingly or at the wrong time of year.

Common mistakes made when it comes to lawn fertilizers are:

  • over fertilizing or applying too much
  • applying at wrong time of the year

Over fertilizing can cause excess leaf growth and limit root growth. Apply fertilizer too heavy and it can burn your lawn.

We offer a variety of fertilizer services for residential, commercial and industrial applications. Please contact our offices if you have any questions.

Fertilizer is complicated. Misapplication can burn your lawn and limit root growth. Make sure you research before applying.

6. Bagging the Clippings

Leave the grass clippings on the lawn, as you mow, to decompose and provide moisture and nutrients. If the grass clippings clump together, make sure to rake them out so they don’t form a thick mat and suffocate the lawn.

7. Not Dethatching

Thatch is the layer of dead organic lawn matter, such as grass clippings and shredded leaves that forms on top of the soil. If the layer of thatch is ½” thick or thicker, it can starve the lawn.

To help grass absorb sunlight, nutrients and water, it’s important to dethatch the lawn at least once a year, preferably in the spring.

Use a thatching rake or rent a dethatching machine.

If your layer of thatch is 1/2″ or thicker, be sure to dethatch once a year.
