Spring is a season of renewal, and there’s no better time to revitalize your lawn after the winter months. Two essential components of lawn renovation in spring are mowing your lawn low and topdressing. In this article, we’ll explore these techniques and how they contribute to the overall health and beauty of your grass.

Mowing the Lawn Low

Timing is Key

As spring begins, it’s time to give your lawn its first trim of the season. However, the secret to successful mowing in the spring is to start when your grass is still dormant but just before it starts actively growing. This typically falls in early to mid-spring when the soil temperature has risen, and the grass is beginning to green up.

Set the Right Mowing Height

When mowing low in the spring, it’s crucial to set your mower at the appropriate height. For most cool-season grasses, a height of around 2 to 2.5 inches is ideal for the first mow of the season. Mowing low at this time helps remove dead grass, thatch, and other debris that may have accumulated over the winter.

Follow the One-Third Rule

Never remove more than one-third of the grass blade’s height in a single mowing session. Removing too much at once can stress the grass and weaken it. If your grass has grown too long over the winter, consider gradually lowering the cutting height in subsequent mows until you reach the desired height. However, as a one off during a lawn reno when you are trying to get your lawn back looking its best you can scalp the lawn and mow it right back using the lowest setting of your mower. It is important to note that if you are doing this you must ensure the lawn is getting enough water and nutrients to survive otherwise it will die off. It is best to only scalp the lawn once it has come out of it dormant stage and is starting to grow again.

Mulch or Bag

Mowing low in the spring also involves deciding whether to mulch or bag the clippings. Mulching the clippings can return valuable nutrients to the soil, while bagging can help remove thatch and debris more effectively. The choice depends on your lawn’s specific needs and your preference. Generally, during a lawn renovation you will want to remove the thatch and clippings to assist with aerating and allowing new grass to grow through.

Topdressing for a Healthy Lawn

Understanding Topdressing

Topdressing is the process of applying a thin layer of soil or a mixture of soil and organic matter to the surface of your lawn. This technique can help improve soil quality, level uneven areas, and enhance the overall health of your grass.

Choose the Right Material

Selecting the right topdressing material is crucial. Compost-rich topsoil or specialized topdressing blends can provide the necessary nutrients and organic matter to support grass growth. However, top soil may have the seeds of weeds within it which may create another issue going forward. Ensure that the topdressing material is free of weeds and pathogens. Washed river sand is another popular option. It provides a good source of nutrients for the soil and doesn’t carry any weeds. It may however have some small rock remaining within the mixture so take care during your first mow.

Application Method

Spread the topdressing material evenly across your lawn using a shovel, wheelbarrow, or a broadcast spreader. Aim for a layer that is approximately ¼ to ½ inch thick. Be cautious not to smother your grass by applying too thick a layer. Ideally, you want to still be able to see the tips of the grass through the top dress material.

Work in Conjunction with Aeration

For best results, consider aerating your lawn before topdressing. Aeration creates holes in the soil, allowing the topdressing material to penetrate deeper and enhance root growth. This can be done by coring the soil and removing plugs or using a folk and aerating boots.

Water and Care

After topdressing, water your lawn thoroughly to help the topdressing material settle and make contact with the soil. Regularly monitor your lawn’s moisture levels and continue with proper watering and maintenance. Fertilizing the lawn is important during a lawn renovation and can be done a few days prior or after the topdressing.

Mowing your lawn low and topdressing it in the spring are valuable techniques for rejuvenating your lawn after the winter months. By following these steps and carefully considering the unique needs of your lawn, you can set the stage for a vibrant, healthy, and lush green space that you’ll enjoy throughout the growing season. Remember that consistent care and maintenance will help ensure the long-term success of your lawn renovation efforts.
