"Our backyard was in need of a redo: We struggled to grow grass, and we wanted a space that would accommodate a trampoline and a small garden, as well as a dining table and sitting area, but still feel green and lush. After meeting with a few landscapers who suggested we get rid of the trampoline, rip up our existing brick patio and put pavers everywhere, we met Alisa from Motti's team. As a landscape designer, she really listened to what we wanted, and had great ideas for how to incorporate it all, as well as suggestions for garden planters and furniture. A week after our meeting, we got detailed plans that showed us just what the yard would look like, as well as what plants would look and work best. We then worked with Motti to tweak the plans, finalize the budget, and pick out materials, etc., and we were able to schedule the project within a few weeks time. Once the job started, Motti's team of workers were professional and efficient, and Motti stopped by daily to check the progress. Our backyard is now a true extension of our living space, and it's welcoming to kids and adults. A great big thanks to Motti and his team!"

Mulch and Topsoil FAQs, answered by experts

Pea gravel is the most common type of gravel, and it can be made of limestone, granite, basalt, sandstone, and many other types of rock. The strength in gravel comes from the distribution across the stones, so while one rock type may not be particularly strong (like sandstone), the matrix of small rocks that is gravel can become incredibly strong when installed correctly. 

This will depend on the depth of the structure. For a landscape, patio, or walkway that’s around 2 inches deep, a ton of gravel will cover around 100 square feet or about 0.6 cubic yards. However, if you’re building a driveway, which should be a minimum of 12 inches deep, you’d need about 6 tons of gravel to cover the same area.

The cost of 200 square feet of pea gravel depends on how deep your installation will be. The pea gravel material alone costs between $15 and $75 per cubic yard. You'll need just under two yards to cover 200 square feet to a depth of three inches, for a total cost of between $30 and $150.

A base layer is typically required when installing artificial grass, and the specific materials depend on the surface where the turf is being placed.

If you are installing artificial grass over soil, you should lay down a sub-base and a weed barrier.

  • Weed Barrier: A fabric weed barrier, weed membrane, or geo-textile paper is essential to prevent weeds from growing through and damaging the turf.

  • Sub-base: This layer provides drainage, support, and prevents the turf from sinking. Common materials include a mixture of gravel and sand, such as crushed miscellaneous base (CMB), decomposed granite, decomposed limestone, or a specifically mixed road base. Other options include silica sand and granite sand.

If you are placing turf over a hard surface like concrete, you can often skip the sub-base and use a padded underlayment or shock-absorbent material like astro-cushion for comfort and safety.

If you are unsure which materials are best for your specific project, it's a good idea to consult with an artificial turf installer.

Weeds can grow through rubber mulch, but it depends on if you removed all the weeds in your garden beforehand. Weeds already in the soil can grow even when using rubber mulch. However, that doesn’t mean that your garden will be littered with rubber and weeds, but it does mean that the occasional weed might still pop up. Another way you can increase your weed suppression is by using landscape fabric as a second layer.
