1. Grass Clippings

Before using grass clippings as mulch, make sure you don't apply too thick a layer, as the grasses tend to mat together and interfere with the soil's air flow cycle. Add a thin layer (under 1 inch) and mix them with other organic debris such as shredded leaves or straw.

2. Leaves

Avoid large or wet leaves, as they mat together promoting mold and poor air flow. Dry and shred leaves with your mower for best results. Leaf mulch contains nitrogen that slowly feeds the roots. Sprinkle fresh soil over the layer so leaves don't scatter on windy days.

3. Shredded Bark

Perhaps the most popular type of dry mulch for trees and shrubs — aesthetically pleasant and excellent for protection. Bark can be acidic, so enhance it with lime as needed. Have your tree service Peru, IL specialists test the soil's acidity before applying.

4. Sawdust

Buy proper mulch-grade sawdust, as chainsaw sawdust contains oil. While its light color reflects heat away from the soil, sawdust can clump and interfere with air flow and nutrient absorption. It can also be acidic depending on source, so consult your tree service Peru, IL experts.

5. Seaweed

Fresh seaweed contains plenty of nutrients and is an excellent insulator and snail barrier. It dries fast, so mix it with grass clippings or other organic materials. Rinse seaweed before use to avoid excess salt in the soil. Have your tree service Peru, IL team test salt levels.

6. Straw

Great for mulching trees and large plantations of ornamentals and shrubs. Straw reflects heat away from soil and contains fewer weed seeds than hay. If aesthetics matter, save straw mulch for your vegetable beds and use a more attractive mulch elsewhere in your landscape.
