If you have a slope or incline on your property, you can turn it into a lovely garden oasis. Where once weeds grew, flowers could grow in abundance. Or perhaps you’d rather have a vegetable garden. Despite the rugged terrain, the slope can become a lovely planted area, turning a liability into an asset.
Terraces Make A Big Change
Putting terraces on a slope can make for some gorgeous results. Not only that, it broadens your options for what can be planted, since you have level areas to work with. The flat area makes it easier to work and work there. Making terraces, however, is unquestionably a lot of work. It can also be expensive depending on the materials used.
Previously, railroad ties were considered a good source of material for making retaining walls for terraces. They’re not used so much these days, however, and especially aren’t recommended for organic gardens. Creating the problem is the creosote used to preserve the wood. Creosote is a toxic substance, and contact with it can irritate the skin. Inhaling creosote fumes can irritate the respiratory trace.
In other words, it’s rather nasty stuff. Besides direct contact, it can leach into the soil and water. Plants absorb nutrients from the soil, and if creosote is in the soil, they can absorb that also. If it’s vegetable plants, then you eat whatever they’ve absorbed. Because of all that, creosote treated lumber for your terracing isn’t a good idea.
Safe Wall Materials And Placement
For small projects where you’re just leveling out a little slope, the new landscaping boards such as those found at Gardens Alive! that are made out of recycled plastics are an option. Use bricks for steeper slopes. Or you could use concrete blocks, modular retaining wall blocks or stone. These masonry options require varying levels of expertise, so be sure you know how to build walls with the materials you opt to use.
The steepness of the slope will dictate the height of the walls since the idea to provide level beds. Higher walls obviously means they need to be that much sturdier. They also should be well anchored. Anchoring the terraces at each end into the slopes is especially important. They also need proper drainage.
The walls will have to bear a lot of weight from the soil pushing against them, and that will increase even more after a rain. Improperly built walls could bow outwards or even collapse.
Building terraces is a big task. If it seems like to much to do yourself, there are landscaping contractors that can do the work for you. Since you’d have labor costs as well as paying for the material, that of course would be more expensive.
Ready The Soil For Plants.
It’s a good idea to enrich the soil before planting because slopes often have poor soil due to erosion. Soil amendments such a well-rotted cow manure, rich loam, compost or other soil amendments to the dirt to make it a better growing medium. If you wish to grow plant that thrive in poor soil, however, you won’t want to enrich the soil very much, if any.
Once the soil is ready, choose your plants, whether vegetables or flowers (DirectGardening.com – Offers quality plants at great prices). A good place for vining plants is along the top edge of the walls, which allows the vines to trail down over the sides.
Improve Your Property With Terraces.
Creating terraces on a slope is a lot of work. Sometimes it’s also a lot of expense. However,it’s a great way to eradicate an eyesore, improve your land, and provide another place for an organic garden full of flowers or vegetables.
There’s never too much space for planting.
Popular Questions
How do you start making terraced gardens for slopes?
Begin by measuring the slope, marking contour lines, and deciding how many terrace levels the site can support. Place each terrace across the slope rather than straight up and down it to slow runoff and reduce erosion. Check the layout with a level before digging, and leave enough space for paths, planting beds, and maintenance.
What materials work best when making terraced gardens for steep slopes?
Use durable materials such as stone, treated hardwood, concrete blocks, or properly anchored landscape timbers. The retaining structure must be strong enough to hold back wet soil and should be built on a stable, level base. Add drainage gravel and a perforated drainpipe behind the wall so water pressure does not damage the terrace.
How can you control drainage when making terraced gardens for slopes?
Shape each terrace with a slight slope that directs excess water toward a safe outlet instead of allowing it to collect behind the retaining wall. Install gravel backfill, drainage pipe, and erosion-resistant channels where water leaves the terraces. Cover exposed soil with mulch or ground covers after planting to limit runoff and soil loss.
What should you plant when making terraced gardens for slopes?
Choose plants suited to the sunlight, moisture, and climate of each terrace, with deep-rooted species on areas vulnerable to erosion. Mix shrubs, perennials, grasses, and ground covers to create layers of roots that help hold the soil. Avoid planting large trees too close to retaining walls because expanding roots can shift or weaken the structure.
