"TrueCare Landscaping gave a very reasonable quote. They showed up promptly. They worked so hard and professionally. The front yard and back yard look AMAZING. They got rid of old mulch, weeds, huge WEEDS, wild honeysuckle everywhere, climbing vines, and trimmed treees. Then they put down new mulch and straighten the rocks. They cleaned up afterwards, and gave tips for keeping the yard in shape. They advised what to do next and in the spring. I will hire them again for future projects. I recommend them to others needing landscaping. You will be happy."

Mulch and Topsoil FAQs, answered by experts

Replace organic mulch every one to two years, depending on the variety. Wood chips and straw, for example, will last a couple of years, while grass clippings and pine needles need replacing every several months. Inorganic mulch—such as rock and rubber chips—can stay in place for up to four years, depending on erosion and general garden upkeep. 

To prepare your yard for river rocks, smaller rocks may require laying landscape fabric to keep the stones from sinking into the ground while encouraging proper water drainage. You should also clear the land of weeds and larger boulders and, in some cases, test the density of the soil to ensure it can handle the weight.

When it comes to which stone is better, crushed or natural gravel, it all depends on the project. Crushed stone is a great base and filler material for projects like retention walls, concrete slabs, driveways, pipes, and drains. Gravel is a common choice for visually attractive landscaping projects like walkways, above-ground drainage systems, patios, and garden borders.

How tall your mulch should be around your tree depends on the type of mulch you use, but aim for 3 to 4 inches as a rule of thumb. You’ll want to avoid simply piling it up in hopes of offering additional benefits to your tree. Volcano mulching is the infamous term for piling way too much mulch against the stem of your tree. This could actually kill your tree or severely harm it, as your tree trunk needs space to breathe without too much moisture.

Most experts recommend a quarter-inch layer of compost for best results, and you will need about .77 cubic yards of material per 1,000 square feet. To measure how much compost to use, take the square footage of your yard and multiply it by .77, then divide that number by 1,000.
