The Magic of Mulch

Danville Tree Removal

You’ve probably heard that mulch is important to your landscape. Have you ever thought about why that is? Apparently lots of people have thought about it, and so much that the phrase “the magic of mulch” has gained popular use. Don’t believe me? Google it.

Why did “the magic of mulch” become a thing, instead of “the utility of mulch” or ”the practicality of mulch”? Probably because what mulch does is pretty whimsical and impressive, really. But before we go into that, what do people use as mulch?

 

Basic Mulch Types

 

When you’re looking for mulch, you’ll find that you have three basic category types: organic, mineral, or synthetic. Organic mulch can be shredded hardwood, bark based, coconut coir, wood chips, corn husks, leaf litter, and other natural plant materials. Mineral mulch includes pea gravel, crushed brick, volcanic rocks, marble chips, and shale. Synthetic mulch can be shredded rubber, black plastic sheeting, and landscape fabric. Sometimes synthetic mulches are layered under organic or mineral mulches.

 

Mulch and the Microbiome

Mineral and synthetic mulches do something good for the miniscule life in your soil: they keep it cool and moist. But organic mulches offer more than that: they contribute new nutrients and living microbes to the rich and bustling microscopic life in the soil. Within soil there are fungus, bacteria, nematodes, algae, earthworms, ants, centipedes, millipedes, beetles, snails, and slugs, all sharing a balanced ecosystem. Organic mulch supports and contributes to that. If your soil were not vibrant with life, your trees, shrubs, and grass wouldn’t be either.

 

Mulch and Water

All types of mulch reduce evaporation of water from the soil. Water is crucial to your healthy garden and trees. Not only do the plants themselves need water, but so do soil-dwelling microbes and tiny animals like ants and worms. This water retention becomes especially important during hot or dry spells or in hot or dry climates. There is no danger that using mulch will keep your soil too wet, mulch brings water management benefits and no drawbacks.

 

Mulch and temperature

Part of the magic of mulch is that it keeps soil and roots warmer in cold weather and cooler in hot weather. It has an insulating property that brings the soil below it closer to middle ground temperatures by reflecting away heat and retaining the warmer ground temperatures when cold hits. Almost all areas experience either hot summers or cold winters, if not both. This makes mulch’s insulatory magic useful everywhere.

 

Mulch and Your Trees

Mulching your trees is pretty easy, and yields great benefit for the tree. What you don’t want is to under-mulch or over-mulch. No sparse see-through layers and no grand mulch volcanoes with your tree trunk erupting out.

Keys to mulching your tree well:

  • Remove grass and weeds within the “drip line”, area under the thickest parts of the tree canopy
  • If there’s old mulch, rake it to make sure it’s not compacted
  • Add about 3 inches depth of fresh mulch covering the “drip line”
  • Make sure the flare of the trunk (where it widens above meeting the ground) is fully above the mulch-line. No mulch should be against the trunk or within the first few inches.

Bark Mulch or Rock Mulch: Which is Better for Garden Beds?

Mulch is great for gardens, helping to retain moisture, protect plants and adding a decorative finish to your beds. Mulch can greatly improve the condition of your garden, replenish the soil and keep your garden neat and maintained. But when it comes to mulching your garden, wood mulch is not the only option. There are many choices of material for mulch, but two of the most common and popular are bark or wood mulch and rock mulch. Both of these mulch types perform the essential functions of retaining moisture in soil and keeping the soil insulated. Here we look at the difference between these two mulch types and which is better for your garden beds.

Bark or Wood Mulch

Bark and wood mulch are organic mulch types that are made from shredded bark or wood. Wood and bark mulch are naturally brown or black, however they can be dyed a variety of colors to match your tastes. Bark and wood mulches are available from professional arborists, who obtain the mulch from healthy trees. Natural wood or bark mulch has an appearance like wood chips or small pieces of bark. It also releases a natural earthy smell when placed on your garden.

One of the most significant and distinctive benefits of wood and bark mulch is that it decomposes and adds nutrients and nitrogen to your soil. Wood and bark mulch is also inexpensive, has a more natural appearance, and looks great in every garden bed. Wood and bark mulch effectively form a preventative barrier against weed growth and help avoid the need for edging material. Wood and bark mulch are also relatively soft and make it easy to garden even with the mulch covering.

However, there are also some disadvantages of wood and bark mulch. One of the most significant disadvantages is that wood and bark mulch needs to be replaced every 1 to 2 years as the mulch breaks down or is washed away. The vibrant color of wood and bark mulch can also fade in sunlight. Wood and bark mulch can potentially draw in pests and insects attracted to the small, broken pieces of wood.

Rock Mulch

Rock mulch offers a polished and flawless coverage for your garden beds. Rock mulch consists of any type of stones or gravel used to provide cover and protection for garden beds. The size of the rocks can range from very small to as large as a fist, and rock mulch is available in a variety of colors.

One of the greatest benefits of rock mulch is that it does not need to be replaced as often as wood and bark mulch. Rock mulch is hardy and won’t wash away or decompose.  Rock mulch can also be ideal for sloped gardens as it holds its position well.

Rock mulch is much more expensive than wood and bark mulch, but it also lasts longer. While rock mulch doesn’t decompose, it may wear thin overtime, and you will need to find the same rock type and color to replace your coverage. One of the disadvantages of rock mulch is that weeds can grow through the gaps in the rock especially if organic matter and debris is allowed to collect on the surface of the rock mulch. Rock mulch is also heavy and difficult to remove if you change your mind or decide to add or take away plants from your garden.

Which Is The Best Choice For You?

Choosing the right mulch type for your garden beds depends on the type of plants you have and the look you’re going for. For plants that need extra nourishment, stable soil temperatures, and potentially moving or replanting, wood or bark mulch is best. if your plants can withstand higher soil temperatures and require less nutrients and nitrogen in the soil, rock mulch may be the best choice for you.

Having a local arborist inspect and analyze your garden bed and plants can help you identify the right mulch choice for you .
