Lawn care is more than simply applying fertilizer. Proper product selection, application rates, timing and weed-control techniques all affect the health and appearance of your lawn.

At Maggio, we use professional products, calibrated equipment and trained technicians to deliver a consistent lawn care program designed around Ontario’s growing conditions. Our technicians also monitor your lawn throughout the season so potential problems can be identified before they become larger issues.

In areas like Alliston, Bolton, Newmarket, Vaughan and across Simcoe County, lawn growth is heavily influenced by our cool-season grasses, clay-based soils, and fluctuating spring and fall temperatures. That means timing your fertilizer properly is key to getting real results.

The most important feeding windows in our region are early spring and fall. This is when your lawn is actively growing and able to take in nutrients efficiently. That’s why we apply a 4-month slow-release fertilizer during these key periods—providing a steady, controlled feed that supports deep root growth, improves colour, and helps your lawn recover from winter stress and summer heat.

Throughout the season, we also include a liquid fertilizer additive with each of our weed control applications. These lighter, targeted boosts help maintain consistent colour and density without pushing excessive top growth—especially important during Ontario’s hot, dry summer stretches.

Neither is inherently better—the best lawn care program uses each type for what it does best.

• Granular fertilizer is best for long-term, slow release nutrition to establish long term health resulting in lush, deep green grass.
• Liquid fertilizer is great for a quick green-up and nutrient boost, but does not come in slow-release and needs to be re-applied often meaning short-lived results and multiple disruptive visits.

At Maggio, we use a combination of slow-release granular fertilizer twice per season plus additional liquid fertilizer within each of our three weed control tanks to nourish your lawn all season long.

Our lawn care products are used according to their product labels and applicable regulations. After an application, customers should follow the post-care instructions provided by Maggio, including any required re-entry period.

We recommend waiting for the liquid products to dry before going onto the lawn to avoid staining your running shoes or pets paws red from the iron.

Fiesta is an iron-based herbicide used to control a range of broadleaf weeds commonly found in Ontario lawns, including dandelion, clover, plantain, chickweed and thistle.

It effectively targets:

• Dandelion (Taraxicum officinale)
• White clover (Trifolium repens)
• Silverweed cinquefoil (Potentilla anserina)
• English daisy (Bellis perennis)
• Bull thistle (Cirsium vulgare)
• Broadleaf Plantain (Plantago major)
• Narrow-leaved Plantain (Plantago lanceolata)
• Creeping buttercup (Ranunculus repens)
• Canada thistle (Cirsium arvense)
• Common chickweed (Stellaria media)
• Dovefoot geranium (Geranium molle)
• Common chickweed (Stellaria media)
• False dandelion (Hypochoeris radicata)
• Wild chamomile (Matricaria chamomilla)
• Slender speedwell (Veronica filiformis)
• Healall (Prunella vulgaris)
• Moss, liverworts, algae and lichens
• Persian speedwell (Veronica persica)
• Shepherd’s-purse (Capsella bursa-pastoris)
• Black medic (Medicago lupulina)

The active ingredient in Fiesta is iron in the form FeHEDTA. These iron molecules are specially formulated to be absorbed by the foliage of the weeds causing a toxic overload of iron – essentially poisoning them to death.

You can expect to see weeds begin to shrivel up about 48 hours after application of Fiesta weed control with full results after one week.

Tough or mature weeds with deep roots might need a second application 3-4 weeks later for total control.

No, Fiesta weed control will not harm your grass. It is a selective product – which means it will damage some plants but not others.

While your grass may absorb small amounts of the iron in the product, it will act as a nutrient and can result in a darker, greener lawn after application.

Fulvic acid acts like a carrier to help transport nutrients directly into plant cells. This additive helps to boost soil structure, improve your lawn’s tolerance to stress and helps grass absorb nutrients more efficiently.

At Maggio, we add fulvic acid to our spring weed control application to help your lawn prepare for summer heat and drought stresses.

Humic acid is a surfactant that’s added to Maggio’s liquid weed control and fertilizers to help products penetrate grass blades and reduce runoff or beading – essentially ensuring more absorption and minimal wasted product.

This additive helps improve root systems, aerate compacted clay soils commonly found in Ontario and encourages beneficial microbial activity in soil.

Our standard lawn care program includes multiple scheduled applications throughout the growing season. The exact timing depends on the treatment and seasonal conditions. Each service includes the treatments outlined in your lawn care program, and we’ll provide post-care instructions after your application.
