Terraced garden

Terraced gardens or hanging gardens are created when garden is on a steep slope. Designing such a garden is a demanding and associated with substantial costs. But it can be very attractive, as it will create view out of the house on a terraced hillside.

Creating terraced garden is financially very challenging because we need to build retaining walls and terrace scarp to give us a levelled beds and soil is not flushed away by water. If the slope is gentle we can build terraces by levelling beds and planting various perennials on newly formed slopes. Roots will hold soil on its place. This method is suitable for terraces that are 10 to 20 centimetres high. If the height is greater, we should strengthen the slope. Up to one meter we can build a stone retaining wall without mortar - dry wall. For security reasons it is recommended that we build it on concrete foundation and create drainage. Instead of dry wall wooden palisades can be used. When the height difference is greater than one meter, we must build concrete wall or stone wall with mortar with at least 40 centimetres deep foundations.

If our garden is in the landslide area, we should consolidate with landslide expert before carrying out any work. Expert will tell us whether it is safe to interfere with the land or not. Working without proper advice can trigger landslide that will not only jeopardize our house, but also the surrounding and cause a lot of damage.

An integral part of terraced garden are stairs. They overcome the height difference and replace long paths. Steps should be made from the same material as the support walls or of a material that is visually similar to the supporting walls. Stairs can be wooden, but avoid wood in shady and moist locations as they will be constantly slippery. Steps should be 15 centimetres high and 35 centimetres deep. This makes walking pleasant and safe. If there are several steps then handrails should be installed.

When you transform the hillside and build terraces, you need to plant vegetation as soon as possible to prevent soil to be flushed away by water. Covering perennials and other plants that crawl and have a lush growth are perfect for terraces. When choosing shrubs you should choose dwarf varieties. Trees should be planted only if they have enough space for roots not to damage walls. Gardens on southern slopes will face water shortages and extensive heat.
