The best time to plant grass seed really depends on what part of Canada you live in and environmental conditions. If you’re in Ontario then the best time would be between late summer to early fall. However, to be sure pick up a metal thermometer and insert it into the ground approximately 7-10 centimeters. Do this for a few days for consistency and ensure no cold spells are on the way.

Grass

Starting a new lawn from seed can produce an awesome new turf area for you, but it is quite important to get the watering just right. Too much and the seed can move or be washed away, to little and you can dry out your little grass plants and they will never make it to be a mature lawn. Grass is like children in a lot of ways. The seeds need a ton of attention when they are brand new babies, but the work will be less frequent and intense when the grass is established. Air temperature also affects how often you need to water. New grass needs to be kept moist but not wet. As a result, you will have to monitor the top layer of soil to see what is needed. If the weather is warm and sunny grass should be watered lightly, many times a day. Once it dries out the top layer of soil should be wet again quickly to prevent soil from crusting over. Also, if any grass is newly germinated, letting it get dry and overheated can kill the baby plants quickly.

As the grass plants get bigger and bigger you can water them less and less. This is because soil dries out from the surface downward. The surface crust dries out first and then with extended heat and non-watering/rainfall the soil becomes drier lower and lower into the profile. When a grass plant is a tiny seedling it has tiny microscopic roots. As a result, it needs to have water constantly supplied to the top few millimeters of soil. As the roots grow deeper they can access water stored deeper in the topsoil. Soil will take a few days to dry out a couple of inches below the surface so ideally we want our grass to grow roots down to this depth to access the water they need. This is called “training” your plants to grow a deep healthy root zone. Ideally you want the water to be just out of reach for the roots so they always have to grow a little further to reach it. You will have to water for longer duration to make sure it has time to soak this deeply into the soil. When new grass has grown to a height of 6 to 8 cm, it may be cut, but not to shorter than 4 to 5 cm. Do not let the grass grow so long that it will not stand upright. Ensure that your mower blade is sharp to avoid unnecessary bruising of the grass plants. While there must be reasonable growth of leaves to develop a healthy root system, mow the lawn regularly so cuttings will be only 12 to 15 mm long. This avoids having to remove cuttings.
