Wood from black walnut, magnolia, eucalyptus, red maple, and invasive species like tree of heaven are not recommended for mulching. These trees release allelochemicals that can suppress plant growth. Some homeowners, however, use wood from these trees for mulching if it is less potent due to age or concentration, or if the plants are not as sensitive to them.

That depends on the number of cubic feet in each bag. Ten 2-cubic-foot bags of mulch will cover 20 cubic feet, while 10 3-cubic-foot bags of mulch will cover 30 cubic feet. Learning how to DIY mulch can save you money and help you repurpose natural items such as wood chips, pine needles, and leaves.

Depending on the size of the river rock and the density of your soil, add woven landscape fabric or sand under river rock. The extra layer will ensure your river rock sits evenly and doesn't create puddles or uneven areas throughout the design. In some cases, nothing is necessary beneath river rock, but be sure to speak with a landscaper to keep your landscaping looking sharp.

The best mulches for trees are wood chips, bark nuggets, or pine straw. Depending on your goals, you may want to avoid using plastic, stone, rubber, or wet grass clippings. Plastic mulch prevents water from reaching the mulched areas of your tree, stones don’t offer any nutritional benefits to the soil, rubber can release byproducts into the soil when it decomposes, and wet grass clippings can lead to rot. 

Plastic may prove beneficial in cold climates in the winter, but wood chips are the ideal option for most environments.
