British Columbia’s unique coastal climate creates distinct challenges for lawn maintenance. Whether you’re in Vancouver, Surrey, or anywhere across the Lower Mainland, understanding when to start and stop mowing can make the difference between a lush, healthy lawn and one that struggles through winter. At Harry’s Lawn Care, we’ve helped countless BC homeowners navigate the complexities of our regional growing season, and we’re here to share everything you need to know about lawn mowing timing in 2026.
Understanding BC’s Growing Season
British Columbia’s lawn mowing season differs dramatically from other Canadian regions due to our mild, wet winters and moderate summers. Unlike the prairies or eastern Canada, BC homeowners often see grass growth starting as early as late February in coastal areas, while interior regions might not begin until late April.
The key to successful lawn care in BC is recognizing that our cool-season grasses (perennial ryegrass, fine fescue, and tall fescue) thrive in the moderate temperatures we experience for most of the year. These grasses actively grow when soil temperatures reach approximately 42°F (5.5°C), which happens much earlier here than in most other parts of Canada.
When to Start Mowing Your BC Lawn in 2026
Coastal BC (Vancouver, Surrey, Burnaby, Victoria)
For homeowners in coastal regions, the lawn mowing season typically begins between mid-March and early April 2026. However, don’t rush to fire up your mower the moment you see green growth. Several critical factors determine the perfect time for that first cut:
Soil Temperature Matters Most: Wait until the ground has warmed and dried out from winter moisture. Mowing on waterlogged soil can cause compaction, damage grass roots, and leave unsightly ruts in your lawn. A good rule of thumb is to wait until you can walk across your lawn without leaving deep footprints.
Watch for 3 Inches of Growth: Your grass should reach approximately 3 inches in height before that first mow. This ensures the grass has enough energy stored in its blades to recover from cutting and continue growing vigorously.
Check the Weather Forecast: BC’s spring weather can be unpredictable. Wait for a stretch of dry days before your first mow. Cutting wet grass leads to uneven results, clumping, and potential disease spread.
Interior BC (Kelowna, Kamloops, Prince George)
Interior regions experience a later start to the growing season, typically beginning mowing between late April and mid-May 2026. The interior’s colder nights and potential for late frost mean patience pays off. Your grass will let you know it’s ready when consistent growth appears and daytime temperatures regularly reach the mid-50s°F (12-15°C).
First Mow Best Practices
When you’re ready for that inaugural cut of 2026, follow these professional lawn maintenance guidelines:
- Set Your Mower Height to 2.5 Inches: Never scalp your lawn on the first cut. Setting the blade higher protects emerging grass from stress and encourages deeper root development.
- Follow the One-Third Rule: Only remove the top third of the grass blade, even if your lawn looks shaggy after winter. If necessary, make multiple passes over several days, gradually lowering the height.
- Ensure Sharp Blades: Dull mower blades tear grass instead of cleanly cutting it, leaving ragged edges that turn brown and become vulnerable to disease. Start the season with freshly sharpened blades.
- Alternate Mowing Patterns: Change your mowing direction with each cut to prevent soil compaction and encourage upright growth.
Peak Mowing Season in BC
April Through June: Weekly Mowing
Once growth accelerates in spring, BC lawns typically require weekly mowing from late April through June. This is when cool-season grasses experience their most vigorous growth due to ideal temperature ranges and typically adequate rainfall.
During this period, maintain your mowing height between 2.5 to 3 inches. This height promotes healthy root development, shades out weed seeds, and helps your lawn retain moisture as we transition into summer.
July Through August: Adjust for Summer Stress
BC summers can bring drought conditions and heat stress, particularly in July and August. During this period, you may need to adjust your mowing schedule:
- Raise Your Mowing Height to 3-3.5 Inches: Taller grass blades provide crucial shade for soil, reducing water evaporation and keeping roots cooler.
- Mow Every 7-10 Days: Grass growth typically slows during peak summer heat. Reduce mowing frequency to avoid stressing your lawn.
- Mow in the Evening: Wait until temperatures cool down to prevent additional stress on your grass.
Many BC homeowners face water restrictions during summer. If you’re letting your lawn go dormant (turn brown) to conserve water, you can stop mowing entirely until fall rains return. Dormant grass doesn’t need cutting and will bounce back once moisture returns.
September: Fall Growth Surge
September is arguably the most important month for BC lawn care. Cooler temperatures and returning rainfall create ideal growing conditions. Resume weekly mowing and maintain a height of 2.5 to 3 inches. This is also the perfect time for lawn aeration and overseeding to repair summer damage.
When to Stop Mowing Your BC Lawn in 2026
Knowing when to put away the mower for winter is just as important as knowing when to start. Many homeowners make the mistake of stopping too early, which can lead to matted grass, increased disease susceptibility, and a sluggish spring recovery.
The Golden Rule: Keep Mowing While It’s Growing
Grass doesn’t simply stop growing when autumn arrives. In coastal BC, grass can continue active growth well into November. The key indicator for stopping is consistent soil temperatures, not just calendar dates.
Coastal BC: Late October to Mid-November
For Vancouver, Surrey, and other coastal communities, plan to continue mowing through October and potentially into mid-November 2026. Stop mowing when:
- Soil Temperature Drops Below 45°F (7°C): At this temperature, cool-season grass growth essentially stops.
- First Consistent Frost: Once you observe frost on your lawn for several consecutive mornings, grass growth has effectively ceased.
- Grass Growth Stalls: If your lawn hasn’t grown noticeably in 10-14 days, it’s entering dormancy.
According to historical data, coastal BC typically experiences first frost around November 2-5, making late October to early November the ideal time for your final mow.
Interior BC: Mid to Late October
Interior regions see earlier dormancy, typically stopping mowing in mid to late October 2026. The first frost usually arrives in early October in these areas, signaling the end of the growing season.
Final Mow Guidelines
Your last cut of the season deserves special attention, as it sets up your lawn for winter success and spring recovery:
- Lower Your Mowing Height to 2 Inches: Cutting slightly shorter for the final mow helps prevent snow mold, reduces matting under snow cover, and makes spring cleanup easier. However, never scalp your lawn – maintain at least 2 inches.
- Time It One Week Before First Frost: Plan your final mow approximately one week before the expected first frost date in your area.
- Remove Clippings: Unlike during the growing season when mulching is beneficial, consider bagging clippings on your final cut to prevent thick layers from smothering grass over winter.
- Clear Debris: After your final mow, thoroughly rake and remove leaves, sticks, and other debris that could smother grass during wet winter months.
Regional Variations Across BC
British Columbia’s diverse geography means lawn care timing varies significantly by location:

Conclusion: Timing Is Everything
Success with BC lawn mowing in 2026 comes down to paying attention to your specific microclimate and grass growth patterns rather than rigid calendar dates. For most coastal BC homeowners, this means starting mowing between mid-March and early April, maintaining weekly cuts through peak growing season, and continuing mowing into late October or early November.
Remember that your lawn will tell you what it needs. Watch for active growth, monitor soil and air temperatures, and adjust your schedule based on weather conditions. When in doubt, it’s better to mow when the grass is actively growing than to put away the mower too early.
