 The Benefits Of Bark on Your Property

Every homeowner or landscape technician should explore some form of mulching. Some prefer traditional mulch, and others want to go the decorative stone route. But if you have your eye on a bark mulch option, we’ve got you covered. We have twelve options at our four locations. If one catches your eye, call for availability. Beyond trapping moisture in the soil, bark mulch provides a range of unique benefits, including the following:

  • Weed Control: Bark is highly effective at keeping weeds at bay, making it an attractive option for any property owner or contractor. It essentially traps weed seeds and prevents them from emerging.
  • Proper Drainage: Bark mulch protects your soil from compacting when you step on it and ensures proper drainage at all times. Considering drainage is an essential job of mulch, that’s important.
  • Protection During Winter: If plants need to be kept cool throughout the year, bark mulch will provide the protection you need year-round.
  • Saves Water: Bark mulch retains water well. In fact, you can expect it to keep up to 70 percent more water. While all mulch options will work, bark mulch is one of the more effective choices.
  • Better Appearance: Plain mulch might not make a splash in the way you’re hoping. Bark mulch is attractive and will give your home a desired look.
