This site might help you. re: how deep do i need to make landscaping rock for groundcover? hey, i have a somewhat large area (about 1730 square feet) that i need to either add mulch or landscaping rock for groundcover as i am tired of pulling weeds.. The landscaping fabric helps hold the moisture in the rocks longer as not all water reaches beneath it. the colorful pebbles known as river rock come in shades of brown and gray. this includes variations of light tan, sandstone, lavenders, and even a deep blue-gray.. Landscape rocks function as both a decorative addition and alternative to mulch in your gardens. choosing rock for garden surfaces provides a permanent feature that won't break down like normal shredded hardwood mulch..
When your rock is placed, smooth out the highs and lows with a rake or shovel for a uniform appearance. all landscape rock will have a certain percentage of fines (dirt) when delivered. finally, you must wash your rock down with a garden hose to clean off any fines and enhance its natural color.. Landscape fabric – a tough, fibrous black fabric installed as a base for the rock on the prepared ground. it is less sun sensitive and easier to install. being porous, it breathes and allows water to flow through it.. Rock gardens, walkways or small patio areas will all benefit from having landscape rock laid down. while the job is often labor-intensive, decorating your landscape with stones is a weekend.
