5 Benefits of Pine Mulch

Pine mulch provides a range of benefits that make it an essential addition to most gardens. It helps to retain moisture and prevents soil-borne diseases from spreading. Pine mulch also keeps the soil moist and moderates soil temperature.

There are two kinds of mulch: organic and inorganic. Organic mulch consists of formerly living material such as chopped leaves or straw, shredded hardwood or pine, pine bark chips, and pine needles. Inorganic mulches include black plastic, shredded rubber, and geotextiles (landscape fabrics).

A well-mulched garden can yield 50% more vegetables than an un-mulched garden that’s the same size, according to Texas A&M Agrilife Extension. There are several organic-type mulches available, but not all types of mulch work best for every plant, so you need to be careful about what kind of mulch you use.

Pine is one of our favorite types of mulch for beginners. It is easy to find, inexpensive, and excellent for most flowers and shrubs. Compared to other mulches, pine bark is relatively lightweight, and it can be spread quickly in the garden.

What is Pine Mulch?

Generally, pine mulch is made from the shredded bark of pine trees. You can purchase finely shredded pine mulch, pine nuggets, or either of these types mixed with the bark of other evergreen trees — such as spruce or fir trees. Pine straw, or pine leaves, is also used as a mulch, but many people prefer the shredded or nugget-type pine mulches for aesthetic reasons.

5 Benefits of Pine Mulch in Your Garden

1. Keeps the Soil Moist

Moisture retention in the soil is important in gardening; it means less manual watering is needed, and a more even supply of water to the plants is available to your plants.

Mulches are known for their ability to retain moisture, particularly organic ones. They conserve moisture by blocking the sun, thus helping the soil beneath to stay cooler and minimizes evaporation.

Pine mulch provides excellent moisture retention benefits, plus it can be worked into the soil once it decomposes, it improves the soil over time.

2. Moderates the Soil Temperature

Applying pine mulch to your flower beds and around your shrubs helps moderate the temperature of the soil during cold winters and hot, dry summers, protecting your plants from alternating freezes and thaws that are known to heave plants out of the ground. 

It is particularly useful in keeping the roots of newly planted shrubs and trees growing as long as possible into early winter and keeps the soil beneath evergreen plants unfrozen longer and deeper so that their roots can properly absorb moisture in winter.

3. Reduces Weeds

If left unattended, weeds will quickly fill in unplanted areas and any open ground around plants. Pine mulch prevents seeds from sprouting, so you don’t have to worry about weeds taking over your garden.

Mulch will block sunlight that weeds need to grow. It helps to keep the soil beneath moist and loose, making the weeds that do sprout easier to pull.

4. Adds Humus to the Soil

Humus is Latin for ‘soil’ and generally refers to the organic component of soil that is formed by leaves and other plant material decomposing. It helps the soil retain moisture and adds powerful nutrients. 

Top layers of forest soils are typically rich in humus. Commercially it is a term widely used that may refer to compost, harvested forest soil, or to other things that have nothing to do with humus at all.

The decomposition of organic mulches, such as pine, adds a layer of humus to your soil and enriches it.

5. It Stays Attractive Longer Than Other Organic Mulches

Mulch generally needs very little attention to function as it should. Mulch colors will fade due to frequent exposure to sunlight. The best way to take care of faded mulch is to add about an inch of fresh mulch.

Pine bark mulch retains its original color longer than most natural mulches, according to a study by the University of Florida Cooperative Extension. Most mulches will turn gray after about a year, and pine bark mulch tends to retain most of its pinkish-brown hue, even after two years.
