June is one of those beautiful transition months in Ontario. Spring rain is beginning to give way to warmer summer days, gardens are filling out, and homeowners are spending more time outdoors.


It is also an important month for anyone starting a new lawn with hydroseeding.


Hydroseeding can establish a lush, healthy lawn surprisingly quickly when the conditions are right, but the first few weeks make a big difference. As temperatures rise in June, keeping newly hydroseeded soil consistently moist becomes especially important.


If you are planning a new lawn this month—or have recently had your property hydroseeded—here is what you need to know.


Is June a Good Time for Hydroseeding in Ontario?


Yes. Hydroseeding can be very successful in June.


The combination of warm soil, longer daylight hours and active grass growth can encourage seed to germinate and establish quickly.


Unlike the cooler temperatures of early spring, however, June weather can dry the soil much faster. That means watering becomes one of the most important parts of establishing your new lawn.


The goal during germination is simple:


Keep the seedbed consistently moist without washing the seed away or creating puddles.



The hydroseed mixture contains grass seed, mulch, fertilizer and other materials designed to help hold moisture around the seed, but it still depends on regular watering.


Your New Hydroseeded Lawn May Look Different Every Day


One of the most exciting parts of hydroseeding is watching the lawn develop.


At first, your property will have the distinctive green appearance of freshly applied hydroseed mulch.


Then you wait.


Depending on the grass seed mixture, soil conditions, temperature and moisture, the first tiny shoots may begin appearing within approximately a week or two.


Do not worry if every part of the lawn does not germinate at exactly the same time.


Different grass varieties germinate at different rates, and areas receiving more sun or moisture may develop faster than others.


Those first scattered green shoots are just the beginning.


Watering Hydroseed During June

Warm June weather means newly seeded soil can dry quickly—especially on sunny or windy days.


During the early germination period, watering several times throughout the day may be more effective than giving the lawn one heavy soaking.


The objective is to keep the upper layer of soil damp.


You are not trying to saturate the ground.


Too much water can cause:


  • puddling

  • erosion

  • seed movement

  • uneven germination

  • damage to the hydroseed layer


Instead, use a gentle sprinkler or watering system that distributes water evenly across the lawn.


On cooler or rainy days, you may need much less supplemental watering. During hot, dry weather, the lawn may require more attention.


The best guide is always the soil itself.


If the surface is beginning to dry, it is time to water.


Avoid Walking on the New Lawn


We know it is tempting.


Once those little green shoots begin appearing, you naturally want to walk across the lawn and inspect your progress.

Try to resist.



New grass seedlings are delicate, and frequent foot traffic can compact the soil or damage young plants before they have developed a strong root system.


Children, pets and regular backyard traffic should be kept off newly hydroseeded areas whenever possible during the establishment period.


Giving your lawn some uninterrupted growing time now can make a significant difference later.


When Will You Be Able to Mow?


Watching your new lawn become tall enough for its first mowing is an exciting milestone.

Rather than mowing simply because a certain number of days have passed, allow the grass to become properly established first.


For many lawns, the first mowing can take place once the grass has reached approximately 3½ to 4 inches in height.


Make sure the lawn is reasonably dry and use a mower with sharp blades.


For the first cut, avoid removing too much of the grass blade at once. A good general guideline is to never remove more than approximately one-third of the grass height during a single mowing.


Young grass is still developing its root system, so gentle treatment during these early weeks pays off.


Do not panic if your lawn looks uneven during its first few weeks.


A newly hydroseeded lawn does not instantly become a mature lawn.


Some varieties of grass germinate earlier than others, and environmental conditions around your property can create differences in growth.


Sunny areas may behave differently from shaded sections. Sloped areas may dry faster.

Spots near buildings or fences can receive different amounts of rainfall and sunlight.


Continue following your watering and lawn-care instructions and give the grass time to develop.


As the individual grass plants mature and begin filling out, the lawn should gradually become thicker and more uniform.


June Is About Building Strong Roots


Everyone wants to see a beautiful green lawn, but some of the most important work is happening where you cannot see it.


Below the surface, young grass plants are developing the roots that will eventually help them tolerate mowing, foot traffic, heat and periods of drier weather.


That is why proper watering and patience are so important during the early establishment period.


A little extra attention in June can help create a stronger lawn for the rest of the summer—and for years to come.


Thinking About Hydroseeding Your Property?
