A Complete Guide for New Sod, Seeded Lawns, and Established Lawns in Southwestern Ontario
As a landscaping and lawn care company in Stratford, Ontario, we install and maintain a lot of grass each season—through sodding, seeding, mowing, and weeding. A freshly installed lawn is a beautiful sight: lush, green, and free of weeds. But keeping it that way can be tricky, and one of the biggest challenges is often watering your lawn correctly.
With growing environmental awareness, many homeowners are cautious about water use. But surprisingly, most overestimate how much water is actually required to keep grass green and healthy. The key is knowing the right watering schedule and technique for your lawn’s stage—whether it’s brand-new sod, freshly seeded, or well-established turf.
Below, we break down lawn watering best practices for each stage to help you get the best results while conserving water.
Watering New Sod
New sod requires consistent, deep watering to help roots establish in the soil.
First Week:
- Water each area daily for 1.5–2 hours.
- Water early in the morning to minimize evaporation.
Second Week:
- Water every other day for the same duration.
Mowing Tip:
- Avoid cutting sod for at least 2 weeks after installation.
- For the first cut, set mower blade to its highest position.
- Wait 3 days before cutting again at the second-highest setting.
- After 4 more days, you can mow at your usual height.
This gradual approach prevents the mower’s suction from lifting the sod before it’s rooted.
Watering a Newly Seeded Lawn
A newly seeded lawn needs frequent, light watering to keep the soil moist without washing seeds away.
Before Germination:
- Water each area for 15 minutes, twice daily—morning and late afternoon.
- Avoid puddles, run-off, or standing water.
- Skip watering on days when there’s sufficient rainfall.
After Germination:
- Reduce to every other day for 15 minutes.
Mowing Tip:
- Wait until grass reaches 4 inches before the first cut.
- Use the same gradual mowing approach as with new sod to protect the young plants.
Tip: Understanding the germination process can help you avoid over- or under-watering during this delicate stage.
Watering an Established Lawn
For healthy, mature grass:
- If you water, water consistently. Irregular watering stresses the roots.
- Water in the morning so moisture penetrates before midday heat.
- Avoid afternoon watering (evaporation loss) and evening watering (increased fungus risk).
- Water long enough for moisture to soak 2 inches (5 cm) into the soil—about 2 hours per area.
- During dry spells, water twice a week.
Pro Tip:
Many homeowners accidentally overwater by leaving sprinklers running too long. A hose timer can help—affordable models range from $15–$40 and are available at most hardware and garden centres.
