Why Professional Fertilization Matters for Scarborough Lawns
Scarborough lawns face unique challenges that generic fertilizer programs can't address. The heavy clay soils in neighbourhoods like Woburn, Centennial, and Agincourt lock up nutrients and resist water penetration — meaning most of the fertilizer homeowners spread from a bag at the hardware store either sits on the surface, runs off, or feeds weeds instead of grass.
Professional fertilization is different. At Dawn Till Dusk Landscaping, our Certified Horticulturist Ted selects the right fertilizer blend for your specific soil type, grass species, and current lawn condition. We use commercial-grade slow-release granular fertilizers that feed your lawn evenly over 6-8 weeks — not the quick-release products that cause growth spikes, excessive mowing, and burn risk during summer heat.
The difference between a DIY approach and a professional program shows clearly by mid-summer. Professionally fertilized lawns maintain deep, consistent colour, resist weed invasion naturally through density, and develop root systems that survive Scarborough's dry July and August stretches without turning brown. The investment pays for itself in a lawn that looks better with less watering and fewer problems.
Our 4-application seasonal program covers your lawn from spring green-up through winter hardening. Each application is timed to your lawn's growth cycle and Scarborough's climate patterns — not a generic calendar. Call (647) 893-3876 for a free lawn assessment and quote.

Fertilizer Treatments We Offer
Scarborough Soil Conditions & What They Mean for Fertilization
Clay Soil Areas: Woburn, Centennial, Agincourt, Malvern
Most of inland Scarborough sits on heavy clay. Clay soil holds nutrients tightly, which sounds beneficial but actually creates problems — nutrients get locked in forms grass roots can't absorb, and the dense structure limits root penetration and water drainage.
For clay-heavy properties, we use slow-release fertilizers with elevated potassium to strengthen roots and include soil conditioners that gradually improve clay structure. Annual core aeration before fall fertilization is essential — it opens channels for nutrients to reach the root zone instead of sitting on the compacted surface.
Sandy Soil Areas: Guildwood, Birch Cliff, Cliffside (Near the Bluffs)
Properties near the Scarborough Bluffs have sandier, well-drained soil. While this means better drainage and less compaction, sandy soil leaches nutrients quickly — fertilizer washes through before grass can fully absorb it.
For these properties, we apply lighter, more frequent doses of slow-release fertilizer and recommend organic matter top-dressing to improve nutrient retention. The goal is consistent feeding rather than heavy single applications that simply drain away.
Mixed & Transitional Soil: Highland Creek, Port Union, West Hill
These neighbourhoods often have mixed soil profiles — clay in some areas, loam or sandy patches in others. We assess each property individually to determine the right approach. Ted's on-site evaluation identifies your specific soil conditions so we can tailor the fertilization program accordingly, rather than applying a one-size-fits-all treatment.

Lawn Fertilization FAQs — Scarborough
When should I fertilize my lawn in Scarborough?
Scarborough lawns benefit from a 4-application seasonal program: early spring (April) with a slow-release nitrogen blend to kickstart growth, early summer (June) with a balanced feed for sustained colour, early fall (September) with a phosphorus-rich formula to support root development after aeration, and late fall (November) with a potassium-heavy winterizer to harden roots before freeze-up. Timing matters — applying fertilizer too early in spring on frozen or waterlogged clay soil wastes product and can burn emerging grass.
How much does lawn fertilization cost in Scarborough?
A single professional fertilizer application for a standard Scarborough residential lawn (3,000–5,000 sq ft) typically costs $80–$140. Our full-season 4-application program runs $280–$480 depending on property size. Bundling fertilization with weekly cutting and aeration saves 10–15% compared to individual services. Call (647) 893-3876 for a free, no-obligation quote based on your specific property.
Is professional fertilization worth it vs. DIY?
Professional fertilization delivers significantly better results for several reasons. We use commercial-grade slow-release formulations that feed your lawn evenly over 6–8 weeks — not the quick-release products found at big-box stores that cause growth spikes and burn risk. As a Certified Horticulturist, Ted assesses your soil type, grass species, and current lawn condition before selecting the right blend. We also calibrate application rates precisely, preventing the over-application that damages lawns and wastes money.
Do you offer organic fertilizer options?
Yes. We offer both conventional and organic fertilization programs. Our organic options use plant-based, slow-release nutrients that are safe for children and pets and improve Scarborough's clay soil structure over time. Organic programs cost slightly more per application but build long-term soil health. We'll recommend the best approach based on your lawn's current condition and your preferences.
What type of fertilizer do you use for Scarborough's clay soil?
Scarborough's heavy clay soil requires specific fertilizer strategies. We use slow-release granular fertilizers with balanced N-P-K ratios adjusted seasonally. For clay-heavy areas like Woburn and Centennial, we emphasize potassium to improve root resilience and include soil conditioners that help break up compaction over time. For sandier soils near the bluffs in Guildwood, we adjust to more frequent, lighter applications since nutrients leach faster through sandy substrate.
