Certified & Insured Guaranteed Service
Master the art of efficient irrigation in our unpredictable climate. From summer droughts to spring thaws—keep your landscape thriving year‑round.
Ontario's freeze‑thaw cycles and humid summers demand a tailored approach. Here's your seasonal roadmap.
Dormant • No watering
Protect outdoor taps
1x / week if dry
Establish new plantings
2–3x / week deep soak
Early morning best
Deep watering before frost
Winterize irrigation
Ontario lawns need about 2.5 cm (1 inch) of water per week during active growth—including rainfall. Use a tuna can test: when it's full, you're done.
Established Ontario native plants are drought‑tolerant. Water deeply every 5–7 days in summer to encourage roots to grow downward.
Saturated soil can drown roots. Avoid walking on wet beds. Delay irrigation until top 5 cm are dry.
Sudden heat spikes. Hand‑water stressed areas. Raise mower height to 8–9 cm for lawn shade.
Evergreens lose moisture. Water evergreens deeply in late October before ground freezes.
