Mulch can be purchased at many different locations, everywhere from your large retail garden supply center to your local garden center. It comes in various different forms, you can buy it in bags, you can buy it in bulk and have it delivered by truck to your home. It all depends on how much mulch you need and what you're going to be using it for. If you're just going to be mulching a small area, then certainly purchase bags of mulch. If you're going to be doing a really, really large area it's going to be more economical to purchase it in bulk and have it delivered to your home. Of course, once you have it delivered to your home, if it's in bulk, then you have to have a wheel barrow so that you can cart it around and get it to your garden areas. Many tree care companies also offer mulch, which is actually ground up parts of trees that they have either removed or done large scale trimmings on. So whenever they run that through their, their, their plant chipper, they actually make a bark mulch that can be used in the gardens. It's a great resource to use because many times these companies are, are cutting down trees that were already dead. So no harm is done to any plants in the making of the mulch.
