The Tricky Part: Putting the Mulch Down
Watch the Tree Collar
If you have a big, mature tree in your yard, you may love the shade, but hate mowing around it. Your mower churns up dirt as you try to cut grass around the tree collar and between roots. You can make your yard care a lot easier, and give your yard a sharper look, by laying down mulch around your tree.
Determine how big you want your mulch circle to be. It should be at least two feet wide, but you can make it much bigger if you want to. The bigger it is, the less competition your tree will have from grass for moisture and nutrients. You can also find a little more room for shade plants to add interest to the mulch circle.
The easiest way to get rid of the grass around your tree is to spray it with Round Up® Weed and Grass Killer. Another way is to place pieces of cardboard over the grass and wet it down. This will help shape it to the contours around your tree and smother the grass.
There are many different ways to border your mulch ring. You can place decorative stones or bricks along the edge, or slice through the turf with an edger to define the mulch area. Just don't cut in too deeply to avoid damaging your tree's roots.
Mature trees are sensitive. They don't like anybody messing with their roots. Too much mulch on an established root system can damage or even kill your tree. Make sure you only put one inch of quality mulch down per year, such as Scotts® Nature Scapes® mulch. That way, your tree's roots won't be troubled, and will have access to more moisture and nutrients, since there's less grass competing for it.
When you lay down mulch, keep it away from your tree's trunk. Tree bark can decay when it's
in constant contact with moisture and microbes. Just keep a little space between your tree and
the mulch, and you'll be fine.

Keep an eye out for any weeds or grass that might creep back. Mulch does decompose, so you'll want to add no more than an inch per year to maintain a fresh look.
