Not all fertilizers are ideal for summer use. Products designed for this season typically focus on balanced nutrients and controlled growth.
Here’s how it works:
Slow-release nitrogen feeds the lawn gradually, preventing sudden growth spurts that can stress grass during hot weather.
Proper levels of nitrogen, phosphorus, and potassium help maintain plant health while strengthening roots and improving resistance to environmental stress.
Potassium plays an important role in helping grass tolerate heat, drought, and disease.
Together, these nutrients help your lawn stay healthy without over-stimulating growth during warm conditions.
Summer fertilizer is typically applied in early to mid-summer, after the lawn has established its spring growth.
In Ontario and similar climates, this usually means:
Avoid fertilizing during extreme heat waves or when the lawn is severely stressed.
For best results:
Fertilizer works best when combined with good lawn care practices.
Mow Higher
Keep grass around 3 inches tall during summer to shade the soil and reduce moisture loss.
Water Smart
Water deeply but less often. Early morning watering encourages stronger root growth.
Avoid Stress
Limit heavy traffic on lawns during extreme heat.
Leave Clippings
Grass clippings return nutrients to the soil and improve lawn health naturally.
Apply summer fertilizer in early to mid-summer, ideally between late June and early August in Ontario. Choose cooler parts of the day, such as early morning or evening, and avoid applying during heat waves.
Yes, but timing is important. Fertilize during cooler parts of the day, such as early morning or evening, and avoid applying fertilizer during heat waves. Using a slow-release fertilizer, like Holmes Grown Summer Fertilizer, helps prevent rapid growth that can stress grass during hot conditions.
Yes. Light watering after applying fertilizer helps move nutrients into the soil where grass roots can absorb them. Ideally, water your lawn within 24 hours of application unless rainfall is expected.
Keep mowing height higher (around 3 inches), water deeply but less often, and apply fertilizer evenly. Avoid over-application, more is not better during summer.
