Mulches, or ground covers as they are commonly referred to, can be any living or non-living material that covers the ground.

We all have a pretty good idea of what a living ground cover would be, but what is a non-living ground cover? A typical list might include bark, grass clippings, decorative rock, compost and even black plastic and news papers. The most commonly used of these in the landscape setting are bark, decorative rock and compost.
Any of these mulching materials are healthful for plants because they aid in moisture retention, reduce evaporation and run off. They keep plant roots cool in hot weather and insulate plant roots in cold weather. But, perhaps the most common benefit of mulch as expressed by many homeowners is the materials’ ability to inhibit weed growth.
To correctly apply mulch, follow these simple instructions:

1. Clear area of existing weeds and debris.
2. Apply a pre-emergent to inhibit weed seed germination.
3. Lay landscape fabric cutting around trees and shrubs. (Landscape fabric is not recommended for use under fine bark or compost.)
4. Apply mulch 2 to 4” deep being careful not let it touch shrub and tree trunks.
How do you choose mulch? Here are some ideas you might consider about your life style:

1. Is gardening your hobby? If so you probably enjoy working in your garden and rearranging your plantings form time to time. Bark is a good choice for you because it is light-weight, easily removed or added to, and in-expensive. Fine bark can easily be worked into the soil as a conditioner.
2. Are you looking for a low maintenance solution? River rock or other decorative rock, combined with landscape fabric offers a weed inhibitor solution that can be 81-90% effective.
3. Looking for street appealing pizzaz? Decorative rock available in many natural colors is great way to coordinate or contrast your landscape with your home’s siding and plantings.
4. Are you a flower gardener? Compost is an excellent fertile mulch for heavy feeders such as roses and perennials. Apply compost at a depth of 1” and work into the soil over the growing season.
