The Benefits Of Raised Gardens | Landscape Gardening Plants

Raised or mounded gardens have an array of home garden benefits, as well as some wonderful garden design aspects. Lifting a garden above the general ground level often results in much healthier plants, and far less gardening problems. Many Australian native plants really benefit from a raised garden, due to the virtual elimination of wet feet.

Mounded gardens often result in reduced maintenance. But one of the greatest aspects of a raised garden, is the improvement in height contrast of various plants, and the exciting gardens that can be created using height as a major garden design tool.

Many of the most beautiful Australian and exotic plants do not like continuous wet feet. Often excessive irrigation, high periods of rainfall, poor mulching practices, and flooding can cause the top root zone area or the crown of a plant to become water logged.

This often results in problems such as Phytophthora or other fungal problems, particularly in the more humid areas such as NSW and Queensland. Just a slight rise of 75mm or more above ground level, can bring amazing benefits. Even plants that can cope with wet feet will still often look much healthier when grown in a slightly raised area, compared to a flat or depressed area.

By using slightly raised areas, the bad effects of these problems can be greatly reduced, as water more easily drains away from the growing point. If a mulch that has many fines is ever used (mulch that almost looks like a soil), a raised garden bed is almost essential, particularly in humid areas. Mulch that has only chunky pieces and no fine particles is of course, a better choice for flat, depressed and even raised areas.

In general, a raised or mounded garden is more forgiving, and can help eliminate many horticultural problems, particularly drainage problems. Apart from healthier plants, raised gardens have many other benefits. For example read more…
