One type of fertilizer is not “better” than the other, but the right lawn care program will utilize a combination of both liquid and granular fertilizers to achieve the best results.

• 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.

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.

Lawn care is a complex science. DIY programs often lead to over- or under-application, missed treatment windows, and unnecessary spending on poor quality products that don’t solve the problem.

At Maggio, we tailor every program to the local soil conditions, weather patterns, and grass types in our area. We use commercial-grade products, calibrated equipment, and proven application techniques to deliver consistent results without the guesswork.

Fiesta is an iron-based herbicide that effectively kills broadleaf weeds commonly found in Ontario.

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 you 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.

Yes, both lawn fertilizers and liquid herbicides used at Maggio are safe for pets and family. 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.

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.
