Deep soil aeration

Aerating involves making holes in your lawn with a tool that removes small plugs of soil.

Why is deep soil aeration a good pratice?

Aeration reduces soil compaction and helps reduce thatch (see why the thatch is a problem). Thus, aeration promotes the rapid infiltration of water into the soil and fertilizer distribution. It helps the roots grow deep. In short, your lawn breathes better!

TRYLAWN recommends aerating your lawn at least once a year.

Ground spreading, compost and fertilizer (top dressing)

Top dressing is the spread of a thin layer of organic matter (black soil, peat moss, compost, sand) on the lawn. The combination of ingredients depends on the type of soil.

Why is top dressing a good practice?

Topdressing gradually improves soil quality, it helps to repair damaged areas and increases the density of the lawn. Especially important if your soil is poor, acid or clay.

TRYLAWN recommands top dressing your lawn at least once a year.

Contact TRYLAWN to top dress your lawn.

Liming (calcium application)

Liming is to apply an agent (calcium, lime, limestone) to restore soil's pH (reduce its acidity).

Why is liming a good practice?

Liming helps to bring the soil pH level back to normal. Therefore, it reduces soil acidity, helps root development, increases fertilizer efficiency, promotes the growth of soil micro-organisms and decreases the spread of weeds.

Caution: A pH meter test is essential to determine the application of liming. Indeed, on a non-acidic soil, adding lime (even small amounts) can create an imbalance in the growth of the lawn.

TRYLAWN can analyze your soil and tell you how much calcium it needs.

Lime treatment is included in our lawn treatment plan.


Fertilization is to give your lawn the nutrients it lacks, and that the soil can not be filled.

Why is fertilization a good practise?

When the grass reaches maturity, it absorbs 10 times its normal consumption of nutrients. Compensation must be provided by fertilizing the soil.

It is best to let our TRYLAWN experts take care of your fertilizing needs. Many aspects must be considered when fertilizing your lawn, such as: When should I fertilize the lawn? How much fertilizer should I use? What kind of soil do I have? How many times should I apply fertilizer? Are there any special considerations if I am need a lake or a waterway? How will it affect my health and the environment?

TRYLAWN use pesticide-free and chemical-free fertilizers, that respect municipal and provincial regulations.

Note that fertilizing is part of our lawn care maintenance plan.


Tips on watering the lawn


Water your lawn longer but less often (every 10 days if there is no rain).

  • Promotes deep rooting. As a result, your grass will be more resistant;
  • Decreases insect infestation during a drought;
  • Over watering your lawn can cause the spread of diseases.

If you do not water your lawn enough, it will become dormant and will stop growing. Leafs and grass blades will become yellow and will die. The roots and rhizomes (subterranean roots) will remain alive until the rainy spring. A properly watered lawn will be protected against foot traffic and to weeds and insect infestation.

Tips on mowing the lawn


Adjust the blade as to obtain an 8 cm cut (3”) all summer long.

  • Prevents the spread of weeds. Less light will reach the ground;
  • Keeps soil humid and less fragile against cinch;
  • Prevent white grubs from laying their eggs as they prefer short grass;
  • Increases lawn productivity and roots conservation. Your lawn will resist harmful pest infestation;
  • Slows grass growth.

Never mow the lawn after it has been raining. The grass must be dry or it will be damaged by the mower blades;

The first mowing of the spring and of the fall should be set at a height of 5 cm;

  • Increases lawn density by stimulating lateral leaf growth;
  • A 5 cm height at the beginning of the season will promote grass growth. However, it will prevent the development of disease at the end of the season.

Leave the grass clippings on the ground

  • Reduces weed development because less light reaches the ground;
  • Keeps the soil humid and protects it from drought;
  • Becomes a natural nitrogen fertilizer;
  • Mow in a different pattern each week so that the clippings don’t form clumps.

Sharpen your lawn mower blades in the spring time as it will help the grass heal. To speed up the decomposition process, use a mulching mower.
