When you should mow your lawn in spring 2025

The first mowing of the season is a transitional rite. It is a sign that warmer days are in front of us and a memory that you will soon spend much more time outside. But before you fire the mower and carve these proper strips into your grass, it is important that the first cut is exactly right. Mowing too early can emphasize your lawn while waiting too long, she can leave a jungle that is more difficult to tame. In the meantime, they may be wondering when to start mowing their lawn – and what else to do to make sure that their grass is healthy and thriving.

When is the best time to mow in spring?

The best time to mow in spring depends on your local climate and how quickly your lawn grows again after winter. In general, you would like to wait until your grass is about 3 inches in size before your first season mower. In most lawns, this will be depending on the temperatures of your region from mid to the end of spring.

According to Chrissie Handley, lawn nursing specialist and garden expert at North West Turf Ltd., “it is important to wait until your grass grows actively, but not too early – growth can be stunt too early.” You also want to wait for the grass to dry out a little. “Mowing wet grass can lead to uneven cuts and even cause lumps that can suffocate the lawn,” adds Handley. The Timing IT Right thus helps to burden the grass and prepare it for a healthy, flourishing lawn in the warmer months.

How short should the grass be for the first mowing of the season?

For your first mower, you would like to cut your grass up to around 2.5 to 3 inches depending on the type of grass. “Don't cut it too short,” warns Handley. “Cutting grass in the early season can expose the root system stress, pests and diseases.” If your grass has grown for a long time in winter, it is best to gradually mow it over a few sessions and reduce the height. This helps to avoid cutting too much at once, which can be stressful for the lawn.

What preparation work should be done before this first cut?

Before mowing, take a few important steps to prepare your lawn and mower for the season:

1. Check your lawn: Go around and check for ruins such as sticks, stones or even fallen branches. Removing these obstacles protects both your mower and your grass from damage.

2. Check your mower: Make sure the blades are sharp and rust -free. “Bully blades tear grass instead of cutting it clean,” says Handley. “This can lead to a ragged lawn that is more susceptible to diseases.” Also ensure that your mower is in good condition by checking the tire pressure, oil and the gas mirror.

3. Fertilize your lawn: Apply a balanced fertilizer to give your grass the nutrients it needs to become strong and healthy. “The use of a spring fertilizer gives your lawn the thrust that it needs after a long winter,” recommends Handley.

4. Swim on leaves: If there are left leaves out of the fall, calculate them before mowing to prevent you from suffocating your grass.
