Benefits of Mulching

  • Man applying mulch

Mulch is as important to your trees, plants, and shrubs as sunlight, fertilizer and water. Think of it as a security blanket covering and protecting the plants root system. Keep these things in mind as you get ready for Spring planting.

Keep Moisture Where it Belongs

A good layer of mulch will keep the moisture in the soil where it belongs! Keeping roots moist but not overly wet which can cause root rot and disease. When summer heat hits, a layer of mulch might be the difference between life and death for plants, especially new plantings.

Mulching Leave Weeds in the Dark

Reduce the amount of sunlight from reaching weed seeds by covering areas with mulch. While you may still have an occasional weed pop up, mulching greatly reduces weeds.

Mulch insulates the soil, creating the buffer between the heat of summer and the cold winter temperatures. Mulch helps to regulate soil temperature by warming sooner in the spring and keeping it cooler in the summer.

Know What You Need to Get the Look You Want

Mulch can help create “that look.” Our color enhanced mulch is made from natural hardwoods and has the highest quality color, giving more vibrant colors longer. Choose from Brown, Red, Gold or Black all with environmentally safe colorant that ensures maximum UV protection.

Mulching is not just a one and done. You will need to add more mulch over the old layers and make sure to use a rake or garden fork to loosen the compacted layer underneath before adding more. Typically, mulch will last 2-3 years depending on the environment. If you want the fresh, new look of colored mulch you may need to add more each season.

How Deep Should it Be?

2-3 inches is generally the recommended depth for mulch around plants. All types of mulch will settle to half its initial depth after the fist season.

    It’s good to know that mulch regulates temperature and keeps the soil cool during the summer. My wife and I are wanting to add mulch to the soil of our gardens in the backyard this spring. Since I can’t find a good price on mulch yet, I’ll keep looking for a garden supplier company that offers a package deal for mulch.

    I never knew that black mulch actually ensures max UV protection for your garden or landscape. My wife and I want to redo the look of our backyard and we think that black mulch would be a perfect color. Seems as if we picked the right color with extra bonus of UV protection.

    Thanks for going over some reasons to mulch. To be honest, I wasn’t away that it could help reduce weeds. It seems like this could be very important in order to save time while also taking good care of a garden.

    Thanks for your question, Scott!
    You are able to put mulch down anytime. We suggest using wheat or all purpose straw. Both are light enough that the plants will not have a problem coming up through.

    When do you put mulch down for the vegetable garden? I am worried that the vegetable plants aren’t strong enough to push through straw for instance.
