Top Rock Landscape Ideas
Rocks are a very attractive addition to any landscape. They make the landscape appear more natural. Here are some ideas for rock placement.
You can use small stones for mulch. This is one of the choices for in-organic mulch, meaning, it doesn't break down like wood chips or leaves. Sizes are from 1/4 to 4 inches average size in bulk. Landscape rock is available in many colors and textures. Besides accentuating colors, landscape rock have several benefits. A fully covered area in the landscape will have more stable temperatures because the sun heats the rocks during the day. Then at night, rock stones slowly release the heat into the ground. Landscape rocks also stabilize ground surface moisture level, by slowing evaporation, thereby reducing your need to water. Use landscape rocks or gravel to replace lawn areas where ever possible.
Medium sized rock, say six to ten inches wide can be placed close together, but not clustered so that they are touching. Leave some space in between the stones.
Landscaping with Rocks
To a landscape designer, stones are like paint to an artist. They add colours and textures to the landscape. Whether they be in a formal setting or more natural layout, landscape rocks are very versatile. Landscape rocks are available in many sizes, shapes, and materials. Many landscape supply centers even offer simulated landscape rocks made from fiberglass. Rock forms include natural stone, gravel in many different sizes and colours, landscape blocks, paver stone, as well as creative natural looking planter pots.
Aside from the visual appeal, rocks in the landscape have other advantages. For desert and arid climates, landscape gravel can be spread out to replace large areas of water consumptive grass. They also help moderate temperatures in the summer and winter. In the summer, they keep the ground cooler in the mornings, reducing ground evaporation. In the winter, the stones heat up in the day and keep the ground warmer through the night. The larger the rocks or the thicker the gravel, the more thermal mass protection you get.
Another advantage of landscape stones is that they reduce maintenance in the yard. Weed seed, that blows in from vacant lots, has difficulty germinating through a thick layer of gravel mulch; thus reducing wear and tear on your back as well as reducing the need for herbicides (weed killers).
The various types of landscape rocks have specific recommended applications in your landscape. Below are descriptions of best uses for different types of rock in the landscape. We start with the smallest types of rocks first, small gravel.
Most landscape rock is sold by weight in bulk. However, smaller stones can be found in plastic bags, and boulders can be sold individually. Buying in bulk usually gives you the best price as it is usually sold by the ton. But you can buy any fraction of a ton that you want, even just one bucket. It is usually can be bought at home garden centers, or dedicated rock retailers. You normally view samples of the various rocks available, then order the amount of weight that you think you will need to cover a given area in your landscape. You can bring your own pick up truck for loading at the rockery, or have the material delivered by dump truck. Delivery is typically $50-$100 per load. Some rockeries offer a discount if you order two different types of stones on one order. The dump truck will unload the aggregate in the street in front of your house. You'll need to cart the material to its final spreading place with a wheel barrel.
Pea gravel, which normally has a size of not more than 7mm (1/4 inch), can be used for pathways. Rather than using concrete side walk, gravel allows rain water to infiltrate the soil, reducing run-off and providing additional water to your plants.
If you don't like the bland color of grey in your pathways, most other landscape rock colours are available in the same size. Pea gravel makes a nice crunching sound when you walk on it. It sounds natural, and no one can sneak up on you.
Ground Cover Landscaping Rocks
The next sized rock is Ground Cover Decorative Rock. It is larger than pea gravel, typically in sizes from 1/2 inch to 3/4 inch to 2×4 inches. It is intended to cover large open areas in your landscape and give a colour base for the plants and large boulders in your landscape. Ground cover stones come in many different colours and textures.
Most are solid pieces, but you can also get red or black lava rock, which is very porous and light weight. Each retailer has their own imaginative names for the different colours of stone. Names like "Apache Brown", "Cherry Mist", "Desert Champagne", "Desert Rose", "Painted Desert", and "Rebel Red" add personality to the rock. But the same rock may have five different names from five different vendors.
River Rock Landscaping
Using river rock (rounded rocks) to simulate a dry creek running out of the house, through the front yard, and to the street has become very popular. The river rocks come in many sizes to suit your needs. Sizes can range anywhere from half inch (1.5cm) to larger than 12 inches (36cm) across. River rock density is usually the highest density of any decorative rock you can buy. A 12 inch potato shaped river rock can weigh 50 pounds. So be careful to have the right equipment and/or help to move such large rocks.
Landscaping With Boulders and Natural Stone
Large boulders in the landscape add something really special, whether it's a desert or evergreen landscape. The larger the boulder, the more stately the appearance. Setting the boulder in place though, is another story. You will definitely need some equipment. Even small shoe box sized boulders can be heavy. There are artificial boulders available that are made from synthetic materials. However, you can really tell the difference. Real boulders change colors according to the seasons, because they have lichens growing on them.
Boulders can be used just about anywhere in the landscape, but here are a few general ideas for placing them in good locations. Plant shrubs around boulders that will mature at about the same size as the boulder. Shrubs that grow larger will overtake the boulder and make it disappear. If this is unavoidable, trim the bushes periodically. Set boulders partially buried so the look more natural in the landscape. Choose a boulder colour that complements that objects nearby. Make sure the boulder belongs and does not look out of place. If using multiple natural stone, make sure they are different sizes.
Landscaping with Caliche Boulders
Much of the western United States has underground deposits of calcium carbonate. These deposits solidify and form large lime-stone boulders underground; typically under your property.
The boulders are random size. They range in size from that of a small potato to as large as a Volkswagen beetle. The larger ones are extremely hard to break up. Construction contractors hate them because it may add weeks to their schedule trying to remove them from the construction site.
The caliche boulders are typically white when first extracted, but oxidise to a light bronze colour after exposure to the atmosphere. They can be varnished to look like natural landscape stone. They are available for free in vacant lots around the city. For your landscape, they can be used to build walls and zone barriers.
Landscaping Blocks, Steps, Brick, and Walls
Stone walls can be used for several reasons in your landscape. Short walls can be used to break a large open area in to a maze that encourages visitors to traverse. Taller walls can serve as property barriers. Choose a block texture and colour that matches the other rocks and paving in your landscape. Many great looking textures are available. Don't just settle for a bland cinder block or brick.
You can also use flattened blocks of random shapes for your pathways. These are sometimes called paver blocks. Some are pre-fabricated, meaning coloured cement is poured in to a mould. The resulting block can either be square, rectangle, or polygonal. Natural slate blocks, called flagstone, are available in many earth-tone colours. They are usually mined from the mountains of the world.
