I have been working this summer in the front yard creating a terraced garden on a sloped yard. My terraced garden started when the bank across the road decided to move itself and a ton of rock and water across the road.
The front yard had become difficult to mow with the slope it has and tree roots popping up, so I decided to move the rock around and create a terraced garden to hopefully prevent more flooding and make the yard easier to work with.
Tomorrow I am going to get perennials for the garden area. It’s not ready to plant yet but I will get the plants now at a reduced price and pot some up and put the rest in a holding garden until I am ready to plant.
If your thinking of creating a terraced garden first you need to identify the slope of you yard and plan accordingly.
There are four basic yard slopes.
Easy slopes are slopes less than 1-foot vertical to 4 feet horizontal (25 degree slope or angle). Such a slope will not require special landscape treatment. You can terrace the area without steps or walls, unless you feel its necessary for safety. Riding mowers may be used safely and efficiently.
A moderate slope ranges from 1-foot vertical to 4 feet horizontal (25%) to 1 foot vertical on 3 feet horizontal (33%). A slope with this range creates a bank where only hand movers are manageable. Its best to plant grass where accessible and use mulch and ground covers for difficult areas.
Avoid single specimens of trees and shrubs on these grades in the grass due to the problems of mowing around them. They can be use only in groups or in mulched bed areas.
Steep slopes will take the most planning but make stunning terraced gardens. A steep slope has a range from 1 foot vertical to 3 feet horizontal (33%) to 1 foot vertical on 2 feet horizontal (50%). Gradients of that kind create banks where only hand movers are not easily manageable. These areas are usually weed wacked, covered with ground cover or have built in terraces.
When dealing with a severely sloped site you have to remember to consider where you want excess water to flow. Make sure it does not flow towards your home, garage or into the neighbor’s property.
If the area you are landscaping has a steep slope, you may want to build terraces or steps made of logs or old railroad ties across the slope to divert water and prevent soil erosion. Between the steps spread a thick layer of wood chips to protect the soil. If the slope is gentle, seeding grass may, using ground cover or using rock may be the answer.
Severe Slopes are slopes 1 foot vertical to 2 feet horizontal (50%) and steeper. Vegetation and plants, including grass and groundcovers, are difficult to establish and demand frequent and skilled maintenance to prevent erosion and unsightliness.
Its best to build terraces if possible and you may want to consider a landscape of hardscape.
My yard is a cross between a sleep slope and a moderate slope. I have had challenges working the design between the two slopes but soon I will have a finished terrace and photographs to show you.
