Use terraces to make flower and vegetable gardening possible on steep slopes, or simply to add interest to your landscape.
In your backyard
Terraces can create several mini-gardens in your backyard. On steep slopes, terracing can make planting a garden possible. Terraces prevent erosion by shortening the long slope into a series of shorter, more level steps. This allows heavy rains to soak into the soil rather than run off and cause erosion.
Materials for terraces
Numerous materials are available for building terraces. Treated wood is often used because of several advantages: it is easy to work with, blends well with plants, and is often less expensive than other materials. There are many types of treated wood on the market--from railroad ties to landscaping timbers. These materials will last for years. While there has been some concern about using these treated materials around plants, studies have concluded that these materials are not harmful to gardens or people when used as recommended. Other materials for terraces include bricks, rocks, concrete blocks, and similar masonry materials. Some masonry materials are made specifically for walls and terraces and can be more easily installed by a homeowner than other materials such as fieldstone and brick. Most stone or masonry products tend to be more expensive than wood.
Height of walls
The steepness of the slope often dictates wall height. Make the terraces in your yard high enough so the land between them is fairly level. Be sure the terrace material is strong enough and anchored well enough to stay in place through freezing and thawing, and heavy rainstorms. Do not underestimate the pressure of waterlogged soil behind a wall. It can be enormous and cause improperly constructed walls to bulge or collapse. Many communities have building codes for walls and terraces. Large projects will need the expertise of a professional to make sure the walls can stand up to water pressure in the soil. Large terraces also need to be built with proper drainage and to be tied back into the slope properly. Because of the expertise and equipment required to do this correctly, you will probably want to restrict terraces you build yourself to no more than a foot or two high.
Building a terrace
The safest way to build a terrace is probably the cut and fill method. With this method, little soil is disturbed, giving you protection from erosion should a sudden storm occur while the work is in progress. This method will also require little, if any, additional soil.
