Mulch can be very beneficial to your landscape. Not only can it save you time by reducing weed germination but it can also help to retain soil moisture.
There are many different types of mulch, ranging from shredded hardwoods, pine bark and straw to non biodegradable materials such as stone and shredded tires. The benefits to using materials such as stone or shredded recycled tires is that you do not have to replace them every year but removal or changes to the landscape such as adding additional plants can be labor intensive.
Biodegradable mulches such as shredded hardwood can be quite beneficial to your plants; not only does it add much needed nutrients to the soil as it breaks down but helps to keep your plant’s roots cool and allows for beneficial organisms to live which will help improve soil structure, allowing for gas and nutrient exchange to occur within the soil.
What type of mulch is installed is typically up to the homeowner and their aesthetic needs.
