Common Lawn Problems in Edmonton and How to Fix Them
Edmonton lawns face unique challenges from clay soil, freeze-thaw cycles, short growing seasons, and harsh winters. Understanding common lawn problems and their solutions helps homeowners maintain healthy, green grass despite Alberta's tough conditions.
Here's how to diagnose the most common lawn issues in Edmonton and fix them effectively.
Brown Spots and Patches
Brown spots are the most common lawn complaint. But "brown spot" isn't a diagnosis - it's a symptom with multiple possible causes.
Dog Urine Damage
Symptoms:
- Circular brown patches with darker green rings around edges
- Located where dogs frequently urinate
- Dead grass in center, extra-green grass around perimeter
Cause: High nitrogen concentration in dog urine burns grass, while diluted nitrogen at edges acts as fertilizer.
Solutions:
- Train dogs to urinate in designated area
- Water spots immediately after dog urinates (dilutes nitrogen)
- Reseed damaged areas
- Consider dog-resistant grass varieties for pet areas
Prevention: Create designated "dog bathroom" area with gravel or mulch.
Grub Damage
Symptoms:
- Large irregular brown patches
- Grass pulls up easily like carpet (roots eaten)
- Typically appears mid-summer to fall
- Birds pecking at lawn (eating grubs)
- White C-shaped larvae visible in soil
Cause: Beetle larvae (grubs) feeding on grass roots under soil surface.
Solutions:
- Apply grub control product in late summer (preventive)
- For existing infestation, apply curative grub control
- Remove damaged sod, add topsoil, reseed
- Maintain healthy lawn (less attractive to beetles)
Prevention: Annual preventive grub control application in late summer.
Drought Stress
Symptoms:
- Grass turns gray-blue before browning
- Footprints remain visible after walking (grass doesn't spring back)
- Affects sunny, high-traffic, or poorly watered areas first
- Typically occurs mid-to-late summer
Cause: Insufficient water, especially during hot, dry periods.
Solutions:
- Water deeply and infrequently (1 inch per week total)
- Water early morning (reduces evaporation)
- Core aeration improves water penetration in clay soil
- Raise mowing height to 3 inches (conserves moisture)
Prevention: Proper watering schedule, core aeration, appropriate mowing height.
Snow Mold
Symptoms:
- Circular patches of matted, gray or pink grass
- Appears when snow melts in spring
- Grass smells musty
- Affects areas with heavy snow accumulation
Cause: Fungal disease developing under snow cover during winter.
Solutions:
- Rake affected areas vigorously (promotes air circulation)
- Most lawns recover naturally when weather warms
- Severe cases may need reseeding
- Improve drainage in affected areas
Prevention:
- Mow shorter for final fall mow (2-2.5 inches)
- Remove leaves before snowfall
- Avoid late-season fertilization (after September)
- Don't pile snow in same spots repeatedly
Fungal Disease (Summer)
Symptoms:
- Brown patches appearing during humid weather
- Patches may have dark borders
- Grass blades have lesions or spots
- Spreads rapidly during hot, humid conditions
Cause: Various fungal diseases (dollar spot, brown patch, rust) thrive in Edmonton's summer humidity.
Solutions:
- Improve air circulation (prune overhanging branches)
- Water early morning only (grass dries during day)
- Avoid excessive nitrogen fertilization
- Fungicide treatment for severe cases
- Remove clippings when disease is present
Prevention:
- Proper watering practices (infrequent, deep watering)
- Good air circulation
- Avoid evening watering
- Maintain proper mowing height
Thin or Patchy Grass
Compacted Soil
Symptoms:
- Grass struggles to grow despite proper care
- Hard soil surface
- Water puddles instead of absorbing
- Common in high-traffic areas
Cause: Edmonton's clay soil compacts easily from foot traffic, heavy equipment, or freeze-thaw cycles.
Solutions:
- Core aeration (late spring or early fall)
- Add compost or topsoil to improve soil structure
- Reduce traffic in affected areas
- Overseed after aeration
Prevention: Annual core aeration, especially in high-traffic areas.
Shade
Symptoms:
- Thin grass under trees or beside buildings
- Moss growth
- Grass struggles despite proper care
- Sunlight less than 4 hours daily
Cause: Insufficient sunlight for sun-loving grass varieties.
Solutions:
- Prune tree branches to increase light
- Overseed with shade-tolerant grass (fine fescue)
- Reduce mowing frequency in shaded areas
- Consider alternative ground covers (hosta, periwinkle)
- Accept that grass won't be as thick as sunny areas
Prevention: Choose shade-tolerant grass seed for shaded areas.
Poor Soil Quality
Symptoms:
- Grass struggles despite watering and fertilization
- Clay-heavy or sandy soil
- Poor drainage or excessive drainage
- Shallow root growth
Cause: Edmonton's native clay soil or poor-quality fill soil from construction.
Solutions:
- Add 4-6 inches of quality topsoil
- Incorporate compost annually
- Core aeration improves structure
- Adjust fertilization for soil type
- Consider professional soil improvement and regrading
Prevention: Establish good soil before sodding or seeding.
Weeds Taking Over
Dandelions
Symptoms:
- Yellow flowers in spring
- Deep taproots
- White seed heads disperse easily
- Return annually if not controlled
Solutions:
- Hand-pull when soil is moist (remove entire taproot)
- Spot-treat with broadleaf herbicide (late May)
- Maintain thick, healthy grass (crowds out weeds)
- Pre-emergent control in early spring (limited effectiveness)
Prevention: Thick grass from proper fertilization, mowing, and aeration.
Creeping Charlie (Ground Ivy)
Symptoms:
- Low-growing vine with scalloped leaves
- Purple flowers in spring
- Spreads aggressively through stolons
- Thrives in shaded, moist areas
Solutions:
- Hand-pull small patches (remove all roots)
- Broadleaf herbicide in fall (most effective timing)
- Improve drainage in affected areas
- Increase sunlight if possible
- May require multiple treatments
Prevention: Maintain dense grass, improve drainage, reduce shade.
Crabgrass
Symptoms:
- Low-growing grass with wide blades
- Spreads rapidly in summer
- Turns brown in fall
- Leaves bare spots when it dies
Solutions:
- Hand-pull before it seeds
- Post-emergent crabgrass killer (early summer)
- Overseed bare spots in fall
- Maintain proper mowing height (3 inches)
Prevention: Pre-emergent control in early spring, thick healthy grass.
Clover
Symptoms:
- Three-leaf plants throughout lawn
- White flowers in summer
- Fixes its own nitrogen (stays green without fertilizer)
- Spreads in thin or nitrogen-poor lawns
Solutions:
- Hand-pull small patches
- Broadleaf herbicide treatment
- Improve lawn fertility (clover less competitive in well-fertilized lawns)
- Maintain dense grass
Some homeowners accept clover: It stays green, requires no fertilizer, tolerates drought, and feeds bees.
Moss Growth
Symptoms:
- Moss growing in lawn
- Typically in shaded, compacted, or acidic soil
- Indicates poor growing conditions for grass
Cause: Combination of shade, compaction, poor drainage, or low soil pH.
Solutions:
- Improve drainage (core aeration)
- Increase sunlight (prune trees)
- Test and adjust soil pH if needed
- Reduce compaction (aeration)
- Overseed with shade-tolerant grass
- Physically remove moss, then address underlying causes
Prevention: Address underlying conditions (shade, compaction, drainage) rather than just treating moss.

FAQ: Lawn Problems in Edmonton
Q: Why is my lawn turning brown in summer?
A: Common causes include drought stress, grub damage, or fungal disease. Check for grubs by pulling up affected grass (if roots are eaten, it's grubs). If grass doesn't spring back after walking, it's drought. If patches have dark borders during humid weather, it's likely fungal.
Q: How do I get rid of dandelions in my lawn?
A: Hand-pull when soil is moist (remove entire taproot) or spot-treat with broadleaf herbicide in late May. Best prevention is maintaining thick, healthy grass through proper fertilization, mowing, and aeration.
Q: What causes brown patches in spring after snow melts?
A: Likely snow mold, a fungal disease developing under snow cover. Rake affected areas vigorously to promote air circulation. Most lawns recover naturally when weather warms.
Q: My grass is thin in shaded areas. What should I do?
A: Grass needs 4+ hours of sunlight daily. Prune tree branches to increase light, overseed with shade-tolerant grass (fine fescue), and accept that shaded grass won't be as thick as sunny areas.
Q: How do I fix dog urine spots?
A: Water spots immediately after dog urinates (dilutes nitrogen). For existing damage, rake out dead grass, add topsoil, and reseed. Train dogs to use designated area.
Q: Why won't my grass grow despite proper watering?
A: Likely compacted soil (common in Edmonton). Core aeration relieves compaction and allows water, air, and nutrients to reach roots. May also be poor soil quality requiring topsoil addition.
Q: When should I treat for grubs?
A: Apply preventive grub control in late summer (July-August). For existing grub damage, apply curative grub control as soon as damage is noticed.
Q: How do I prevent lawn problems?
A: Maintain healthy grass through proper mowing (3 inches), correct watering (1 inch/week), annual core aeration, and appropriate fertilization. Thick, healthy grass prevents most lawn problems.
