Bark Mulch: The Secret Ingredient for Healthy Plants and Soil

Table of Contents


Have you ever stopped to consider the unseen heroes of your garden? While vibrant flowers and flourishing vegetables tend to steal the show, the health of your soil plays a critical role in their success. For many American gardeners, bark mulch serves as a powerful and versatile tool that nourishes the earth and fosters a thriving ecosystem.

In this blog post, we’ll explore why bark mulch is the secret ingredient for healthy plants and soils and reveal how it can transform your gardening experience in Eatonville, Graham, Tacoma, Gig Harbor, Lakewood, Port Orchard, Steilacoom, Puyallup, and surrounding areas.


What is the Best Mulch for Soil Health?

While various materials can be used as mulch, bark mulch stands out as a favorite amongst knowledgeable American gardeners for several reasons. Wood chips and bark decompose slowly, releasing essential nutrients back into the soil over time. This organic matter feeds the microorganisms that live in the soil, promoting a healthy and balanced ecosystem. Additionally, bark mulch helps retain moisture in the soil, reducing the need for frequent watering, especially during the hot summer months. 

Here at Randles Sand and Gravel, our friendly staff can assist you in selecting the perfect type and quantity of bark mulch for your landscaping needs in the Eatonville, Gig Harbor, Lakewood, Port Orchard, Steilacoom, Puyallup, Tacoma, and Graham areas.


What Does Bark Do for Soil?

Beyond the benefits mentioned above, bark mulch offers a multitude of advantages for your soil health:

1. Suppression of Weeds: 

A healthy layer of bark mulch effectively smothers weed seeds, preventing them from germinating and competing with your desired plants for water and nutrients. This translates into less time spent weeding and more time enjoying your beautiful garden.

2. Temperature Regulation: 

Bark mulch acts as an insulator, helping to regulate soil temperature. It shades the soil during the summer, keeping it cool and moist. Conversely, in the winter, it provides a layer of protection from the harsh elements, safeguarding your plant roots from freezing.

3. Erosion Control: 

Bark mulch helps to prevent soil erosion caused by wind and heavy rain. This is particularly important on slopes or areas with exposed soil.


What is the Best Use of Bark Much?

The beauty of bark mulch lies in its versatility. Here are some of the most common applications:

Around Trees and Shrubs:

  • Benefits: 

Apply a 2-3 inch layer of bark mulch around the base of your trees and shrubs, extending outwards to the dripline (the outermost reach of the branches). This creates a zone that retains moisture in the root zone, reducing watering needs by up to 50%. The mulch also suppresses weed growth, eliminating competition for water and nutrients. Additionally, the insulating properties of bark mulch help regulate soil temperature, keeping roots cool in summer and protected from harsh winter freezes.

  • Application Tips: 

Create a “donut” shape around the trunk, leaving a few inches of space free to prevent moisture build-up and potential disease. Replenish the mulch layer every 2-3 years as it decomposes.

Flower Beds:

  • Benefits: 

Beyond aesthetics, bark mulch plays a crucial role in flower bed health. It reduces weed growth, allowing your prized flowers to flourish without competition. The mulch also helps retain moisture in the soil, minimizing watering frequency, especially during hot and dry periods. Additionally, a layer of bark mulch keeps the soil cooler in summer, preventing delicate flower roots from overheating.

  • Application Tips: 

Leading bark mulch experts in Puyallup reveal that you can apply a 1-2 inch layer evenly throughout your flower beds. Ensure the mulch doesn’t touch the base of your flowers, as this can trap moisture and encourage rot. Choose a bark mulch color that complements your flower varieties and overall garden design.

Vegetable Gardens:

  • Benefits: 

While using bark mulch in vegetable gardens requires a bit more caution, its benefits can be significant. A thin layer (around half an inch) of bark mulch can effectively suppress weeds, saving you time and effort. The mulch also helps retain moisture in the soil, reducing the need for frequent watering, which is crucial for some vegetables.

  • Application Tips: 

Apply the bark mulch sparingly and keep it away from the stems of your vegetables to prevent rot. Choose a finer textured bark mulch that decomposes more quickly, adding organic matter to your garden soil. Consider using a barrier like cardboard or landscaping fabric underneath the mulch to prevent weeds further and keep the mulch away from your vegetables.

Pathways and Playgrounds:

  • Benefits: 

According to the top bark mulch specialists in Port Orchard, this organic matter isn’t limited to garden beds. Coarser varieties of bark mulch can be used to create attractive pathways throughout your garden. The mulch provides a natural aesthetic, prevents weed growth, and offers a comfortable walking surface. Playground areas can also benefit from a layer of bark mulch, which acts as a safe and cushioning surface for children.

  • Application Tips: 

Choose a larger bark mulch for pathways that create a stable walking surface. Apply a 3-4 inch layer to suppress weeds and create a defined path. In playgrounds, ensure the mulch depth is sufficient to absorb impact and meet safety regulations. Opt for rounded or shredded bark mulch to minimize the risk of splinters.

  • Shredded Hardwood Bark: 

This versatile workhorse is a favorite among many gardeners. Its slow decomposition rate translates to long-lasting benefits.

  3. Pathways (using a coarser grade)
  • Douglas Fir Bark: 

This aesthetically pleasing option boasts a reddish-brown color that complements many garden designs. Douglas Fir bark is a good choice for acidic soil beds due to its slower decomposition rate, which helps maintain lower pH levels. Here are some ideal uses:

  1. Around acid-loving plants like azaleas, rhododendrons, and blueberries
  2. Flower beds with acidic soil
  3. Decorative pathways
  • Redwood Bark:

This finely textured mulch offers a visually distinct look and decomposes more quickly than other options. Hemlock bark is another excellent choice for acidic soil beds:

  1. Around acid-loving plants

  3. Vegetable gardens (use sparingly and keep away from vegetable stems)
