Lawn & turf FAQ

about mowing the lawn

  • What is the ideal height to mow the lawn?

    The first spring cut should be short (5 cm or 2”)

    Adjust your blade to 8 cm (3”) during the rest of the summer

    The last cut of fall should be 5 cm or 2”

    Long grass will keep the soil shaded, fresh and humid. It will also increase root development.

  • When should I mow the lawn?

    Mowing is better when the grass is dry, in the evening or when it is cloudy outside. Never mow the grass when it is wet.

    The grass must be dry or it will be damaged by the mower blades.

    You should mow the lawn less when it is very hot outside. Never mow more than one third of the height of the grass.

  • Why is it important to keep my mower blades sharpened?

    A dull or broken blade will pull out the grass instead of cutting it. A cleaner cut heals more easily.

  • Should you pick up grass clippings?

    TRYLAWN does not recommend that you pick up your grass clippings; in fact, leaving them on the lawn is good for it. To speed up the decomposition process, use a mulching mower or run a regular lawnmower back and forth over the clippings. Finally, mow in a different pattern each week so that the clippings don’t form clumps.

About watering the lawn

  • How often should I water the lawn?

    Water your lawn longer but less often (every 7 to 10 days if there is no rain).

  • What is the best time to water the lawn?

    It is better to water the lawn in the early morning or in the early evening when the temperature is cooler and it is less windy. If you decide to water the lawn in the early evening, make sure the grass leaves will be dry before night fall. Wet grass increases the spread of fungal disease. It it not recommended to water the lawn in hot weather as up to 50% of the water will evaporate between infiltrating the soil.

  • How do I know if I watered enough?

    Use the following trick to know if you’ve sufficiently watered your lawn. Place 4 or 5 small containers (about the same size) at different spots on the grass. Stop watering the lawn when you see about 2.5 cm of water in each container. Water must penetrate the soil to at least a 10 cm depth.

about thatch

  • What is thatch?

    Thatch is essentially a layer of partially decomposed stems, rhizomes and roots that forms between the lawn and the surface of the ground. If a thick layer (1-2 cm) of organic matter prevents you from touching the ground, then you have thatch.

    A thick (more than 1 cm) layer of thatch, however, can prevent water and air from reaching the soil. It also tends to harbour some kinds of insects and promote disease.

  • Why is thatch problematic?

    A thin layer of straw of about 1.5 cm is advantageous because it acts as a mulch to protect the soil underneath against the loss of moisture. It is also helps prevent the establishment of weeds.

    However, when the thatch layer becomes thicker, it becomes detrimental to the health of the lawn. Thatch amplifies the problems caused by insects or diseases or increases the risks of getting some.It results in desiccation of the grass in patches, as it repels water. Its density prevents pesticides and fertilizer from reaching the soil.

  • What is the solution for thatch?

    The lawn must be properly maintained. It is necessary to proceed to a soil pH analysis as an acidic soil slows down thatch decomposition. The lawn must be aerated and dethatching should be performed in the fall.

about white grubs

  • What are white grubs?

    White grubs are the larvae of certain beetles, such as June beetles and chafers. Grubs feed on the roots of lawn grass. Grubs are white or yellowish and have C-shaped bodies.

  • How do I know if I have a white grub problem?

    Damage caused by insects is first noticed in irregularly shaped zones of yellow grass of varying dimensions. If you pull on the grass where it is damaged and it lifts in a section like a sheet of sod, the white grubs are surely implicated. Use a knife to cut 3 sides of a 30 cm sheet of grass. Roll it up. If you see more than five to ten larvae, then your lawn is infested.

  • How do I get rid of white grubs?

    A healthy lawn is naturally protected against diseases and harmful pest. Necessary lawn care must be applied (see our Lawn Care Guide).
