Mulching around trees is essential to keeping them healthy. Mulch conserves moisture, improves soil health and keeps grass and weeds from competing with your plants for nutrients. Learn the basics and how to use Roundup® products to prep your mulch beds.
Step 1. Size Up Your Mulch
Determine how big you want your mulch circle to be around each tree. 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.
Step 2. Remove The Grass The fastest and easiest way to get rid of the grass around your tree is to spray it with Round Up® Weed & Grass Killer. If you have a large area to treat and own a tank sprayer, you might want to use economical Roundup® Weed & Grass Killer Concentrate Plus. When spraying, be sure to aim away from desirable plants or shield them from spray with a piece of cardboard or plastic. Wait 24 hours after using Roundup® products to plant flowers, trees or shrubs. Always read and follow label instructions.
Another way to control weeds 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.
Step 3. Choose Your edging
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.
Step 4. Lay Down The Mulch
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. 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.
It's important to when you lay down mulch to 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.
