If you’re looking to keep your lawn healthy and lush throughout the year, fertilization is an essential part of lawn care. A well-fed lawn not only looks beautiful but also has better resistance to pests and diseases. However, applying fertilizer at the wrong time can do more harm than good. In Ontario, the timing of lawn fertilization can vary based on the type of grass you have, but here are some general guidelines to follow.
Early Spring
The best time to fertilize your lawn in Ontario is early spring, usually between mid-April to early May. This timing allows the grass to take advantage of the nutrients and develop strong roots before the heat of the summer arrives. However, it’s important not to fertilize too early when the ground is still frozen or too wet, as this can cause the fertilizer to run off and pollute nearby water sources. Wait until the ground has thawed and dried out a bit before fertilizing.
Late Summer
The second best time to fertilize your lawn is in late summer, usually between mid-August to mid-September. Fertilizing during this time can help your lawn recover from the stress of summer heat and prepare for the upcoming cooler months. However, be sure to avoid fertilizing too late in the season, as this can cause the grass to grow too much before going dormant in the winter.
Choosing the Right Fertilizer
When choosing a fertilizer, look for one with a balanced ratio of nitrogen, phosphorus, and potassium (NPK). A good ratio for Ontario lawns is 4:1:2 or 3:1:2. Avoid fertilizers with high levels of phosphorus, as this can contribute to water pollution. Also, choose a slow-release fertilizer to provide a steady supply of nutrients to your lawn over several weeks.
Application Tips
When applying fertilizer, be sure to follow the instructions carefully and apply the correct amount for your lawn’s size. Over-fertilizing can damage your lawn and harm the environment. You may also want to consider using a spreader to apply the fertilizer evenly and avoid creating uneven patches.
In conclusion, the best time to fertilize your lawn in Ontario is early spring and late summer, with a balanced fertilizer containing a 4:1:2 or 3:1:2 NPK ratio. Follow the instructions carefully and avoid over-fertilizing to keep your lawn healthy and beautiful throughout the year.
