New Sod Care Guide
for the Okanagan Valley
Everything you need to know to keep your new sod alive and thriving in the Okanagan's semi-arid climate. Print it, stick it on the fridge.
⚡ Quick Reference — First 48 Hours
- 1. Water sod within 30 minutes of laying — soak until water pools briefly on surface
- 2. Water again in the evening if installed in the morning
- 3. Stay off the sod — no foot traffic, no pets, no kids for at least 2 weeks
- 4. Lift a corner the next morning — the soil beneath should be dark and moist to a depth of 4 inches
- 5. If edges curl or sod feels crunchy, water immediately — the Okanagan sun dries sod fast

1 Watering Schedule
Week 1–2: Establishment Phase
Goal: Keep the sod and the top 1 inch of soil wet at all times.
| Time | Duration | Notes |
|---|---|---|
| 6:00 AM | 15–20 min | Before the sun heats up — most critical watering |
| 12:00 PM | 10–15 min | Midday top-up — prevents edges from curling in heat |
| 5:00 PM | 15–20 min | Evening soak — lets water absorb overnight |
When temperatures exceed 35°C (common July–August), add a 4th watering at 2:00 PM. The dry air and strong sun can dry sod in hours. If you see sod turning blue-grey, it is dehydrating — water immediately.
Week 3–4: Transition Phase
Goal: Encourage roots to grow deeper by watering less often but longer.
| Frequency | Duration | Depth Target |
|---|---|---|
| Once daily (early morning) | 25–30 min | Water should reach 3–4 inches deep into soil |
Test root hold: gently tug a corner of the sod. If it resists and does not lift easily, roots are anchoring. If it pulls right up, keep on the Week 1–2 schedule a few more days.
Month 2+: Maintenance Phase
Goal: Deep, infrequent watering to build a drought-tolerant lawn.
| Season | Frequency | Duration | Notes |
|---|---|---|---|
| Spring (Apr–May) | 2x per week | 25–30 min | Soil is still cool; do not overwater |
| Summer (Jun–Aug) | 3x per week | 30–40 min | Deep soak early AM; check municipal water restrictions |
| Fall (Sep–Oct) | 1–2x per week | 20–25 min | Taper off as temperatures drop |
| Winter (Nov–Mar) | None | — | Lawn is dormant; snow provides moisture |
2 First Mow & Mowing Tips
When to first mow: Wait until the sod has rooted — typically 2–3 weeks after installation. Test by gently tugging a corner. If it resists and stays put, you are good to mow.
First mow height: Set your mower to 3 inches (7.5 cm). This is higher than normal to avoid stressing the new grass. Never remove more than one-third of the blade length at a time.
Ongoing mowing height: For Okanagan lawns, keep your grass at 2.5–3 inches year-round. Taller grass shades the soil, reduces water evaporation, and helps your lawn handle the summer heat.
Keep your mower blade sharp. A dull blade tears grass instead of cutting it cleanly, leaving ragged brown tips that are more vulnerable to disease and heat stress — both common problems in the Okanagan.
3 Fertilizer Schedule
Do not fertilize new sod immediately. Wait 4–6 weeks after installation for the roots to establish before applying any fertilizer. Fertilizing too early can burn tender new roots.
| Timing | NPK Ratio | Purpose | Notes |
|---|---|---|---|
| 4–6 weeks after install | 10-20-10 | Starter fertilizer — high phosphorus for root growth | Water in immediately after applying |
| Early spring (April) | 20-5-10 | Spring green-up — high nitrogen for blade growth | Apply when lawn starts actively growing |
| Early summer (June) | 20-5-10 | Sustain growth through hot months | Use slow-release formula to avoid burn |
| Early fall (September) | 10-10-20 | Fall winterizer — high potassium for cold hardiness | Most important application for Okanagan winters |
| Late fall (October) | 10-10-20 | Final winterizer — helps lawn survive freeze-thaw cycles | Apply before first hard frost (typically mid-October) |
Never fertilize in July or August during peak Okanagan heat. High temperatures + fertilizer = burned, stressed lawn. If your lawn looks pale in mid-summer, it is likely heat-dormant — not nutrient-deficient. Water deeply instead.
4 Okanagan-Specific Tips
📅 Best Times to Lay Sod
- Best: Late April – May (soil warming, consistent rain)
- Good: September (cooler temps, fall rain helps roots)
- Avoid: July – August (35°C+ heat stresses new sod)
- Avoid: November – March (frozen ground, dormant grass)
☀️ Surviving Okanagan Summers
- Temperatures regularly hit 35–40°C in July and August
- Water early morning (before 7 AM) to minimize evaporation
- Never water in the afternoon — most of the water evaporates before reaching the roots, wasting water
- Raise your mowing height to 3.5 inches during heat waves
- Check municipal watering restrictions — many Okanagan cities restrict lawn watering to specific days
❄️ Preparing for Okanagan Winters
- Last mow: mid to late October, at 2.5 inches
- Apply winterizer fertilizer (high potassium) in September and October
- Okanagan winters bring freeze-thaw cycles that can heave new sod — ensure sod is well-rooted before November
- Avoid heavy foot traffic on frozen lawn
- First frost: typically mid-October in Kelowna; earlier in Vernon and higher elevations
🏔️ Altitude & Microclimate
- Valley floor (Kelowna, Penticton): Warmest — longest growing season, most heat stress
- Benchlands (West Kelowna, Lake Country): Slightly cooler, better air drainage
- Northern valley (Vernon, Salmon Arm): Shorter season, cooler summers, earlier frost
- Adjust watering and fertilizer timing based on your microclimate — benchland properties may get away with less water than valley-floor lots
Most Okanagan municipalities enforce lawn watering restrictions during summer. New sod typically qualifies for a temporary exemption — contact your city hall before installation to arrange it. Exemption periods are typically 14–21 days depending on your municipality — contact your city hall to confirm.
5 Troubleshooting Common Problems
Sod edges curling or shrinking
Cause: Not enough water — edges dry out first. Fix: Hand-water edges separately and ensure sprinklers reach all edges. In Okanagan heat, edges can curl within hours.
Yellow or brown patches
Cause: Uneven watering, air pockets under sod, or sod sat on pallet too long. Fix: Roll the area lightly to remove air pockets. Adjust sprinklers for even coverage. If sod was stacked on a pallet for more than 48 hours in summer heat, it may already be dying.
Sod lifting easily after 3 weeks
Cause: Roots have not anchored, often from overwatering (soil too soggy) or compacted subsoil. Fix: Ensure the soil beneath was properly prepared before sodding. Aerate compacted areas. Reduce watering frequency slightly to encourage roots to search for water.
Mushrooms appearing in new sod
Cause: Normal — mushrooms feed on organic matter in the soil. Common with frequent watering. Fix: Pick them off, reduce watering slightly. They will disappear on their own as watering decreases.
