A layer of mulch reduces the chance of weeds sprouting by more than 80%. If you have never used mulch you will be surprised that it is not just decorative but beneficial to the health of the bedding area.
It helps your soil hold onto moisture so that you needn’t water so often.
It also keeps your soil from getting so compacted when you step on it to maintain your garden, and keeps hard rains and hot sun from forming a crust on your soil’s surface.
It keeps plants’ roots cool in summer and warm in winter.
It helps support the beneficial micro-organisms and worm populations that keep your soil aerated and help change the existing nutrients in your soil into a form your plants can use.
It can help keep some soil-borne bacterial diseases from harming delicate, over-bred plants like many roses.
In some cases, mulch can help with erosion control by not allowing hard rain to wash away topsoil and stabilizes young plant growth from wind.
For all these reasons, if you want a low-maintenance garden with healthy plants, mulching is the one thing you can do to have an immediate, dramatic impact on the time you spend weeding, and the overall appearance of your yard.
Rock Planting Beds
There are many good reasons for using rock mulch in the landscape. It’s a material that doesn’t decompose into the soil and does not require regular replacement, so it can be more economical than bark mulch. It’s available in a wide variety of colors, shapes, sizes, and textures.
Pea gravel mulch consists of small rock fragments and is available in different sizes ranging from 1/8 of an inch to 1/4 of an inch and up to 1 ¼ , and a variety of colors including translucent, beige, yellow, and gray. Quartz gravel mulch is a beautiful, long lasting translucent rock cover available in purple, rose, and pink. Quartz has a smooth surface and reflects light.
Granite mulch is a hard, rough rock material available in a variety of shades of gray, red, white, and black. It is chipped rock pieces with rough edges. River rock mulch is composed of round, smooth stones in a mixture of grays and browns. It’s a heavy mulch to apply.
