It is important to know when to replace mulch on the calendar. The best times of year for mulching in Ohio are spring and fall, according to OSU. Replacing mulch during the right time of year can help you get the most benefits from your mulch.

Replacing Mulch in the Spring

By mid to late spring, the soil is dry after winter’s rain and snow and has warmed up from cooler temperatures.

How to Replace Mulch: Dos and Don’ts

There are many things to keep in mind when replacing mulch. Here are some dos and don’ts to help you get started.

  • Do make sure the area is weed free before replacing mulch. Mulch is good for suppressing weeds. Before you apply your new mulch, ensure that the area is free of weeds. This will help your mulch stop future weed growth and help stop weed seeds from growing.
  • Don’t take a one-size-fits all approach to mulch depth. Most garden experts recommend that you use about 3 inches of mulch in your garden or bed. However, the size of the mulch you choose might influence how deep you want it to be. According to information from Lowe’s, the larger the mulch pieces, the deeper the mulch you should use. Smaller pieces of mulch will work into the soil more quickly and require fewer layers of mulch.
  • Do be aware of when to apply mulch. The OSU horticulture extension office suggests applying mulch in the spring and fall. In the spring, the soil has warmed up and dried out from winter’s rain and snow and is ready for mulch. In the fall, applying mulch can help protect plants from coming winter weather.
  • Don’t put mulch on the base of buildings, plants, trees or shrubs. It is wise to leave a few inches of room between the base of your plants, trees, shrubs and buildings when mulching. Having your mulch too close can trap moisture and attract certain insects.
  • Do measure your garden or bed before you mulch. Knowing how big the area you’d like to mulch is will help you determine how much mulch you need. For example, because each bag of Mulch America mulch holds about 2 cubic feet, you’d need about 6 bags to over a 48-square foot mulch bed at a 3-inch depth.
  • Don’t wear your best when replacing mulch. Replacing mulch can be a dirty job. It is wise to dress in old clothes when replacing mulch. Colored mulch can leave a residue on your skin and clothes, which won’t always wash out.
  • Do water your plants after you replace mulch. After your mulch is spread around the desired area, you’ll want to water your plants. The mulch will allow the moisture to penetrate and will help nutrients seep into the soil.
  • Don’t forget to water. After you have your mulch spread, water your plants. This will help the bed retain moisture.
  • Do rake every few months to make the color last. Mulch America’s triple processed, color enhanced mulch will look great all year long. You can keep your mulch looking fresh by raking it to turn it every 3 or 4 months. This will help your mulch keep its rich color.
