Soil erosion and mudslide are the common problems with a slope. But you can reverse this problem and transform that slope to something you can be proud of—a garden. What’s best about this is that you’ll not only be cultivating beautiful plants on the slope, you’ll be helping the soil prevent future erosion or mudslide, too. The more roots the soil has, the more compact it can become. So that’s solving one problem with a literally beautiful idea.
- Testing the soil. The soil is classified on various grades. Three percent or lesser is the best since it doesn’t need any special planting. Three to 10 percent, on the other hand, already needs a special erosion control while 10 percent and more will need retaining walls. If you know how to determine the soil grade, then do it. But if not, a landscape professional can do this job for you. He can also help you plan how you want the garden be arranged on that slope.
- Choosing plants. The best plants for a slope are those that have extensive root system and can spread the roots so quickly. This way, you can prevent soil erosion. A woody shrub is among your best choices because it won’t need tedious maintenance after growing the roots. Other plants you should consider on your slope garden are Azalea, Clematis or Lincoln Star, Siberian Iris, Geranium or Johnson’s Blue, Sisyrinchium Striatum, Wallflower, Bergenia, Catmint, Lady’s Mantle, Achillea, Wild Cherry, and Lamb’s Ears. With these so many choices, it’s very possible to create a very colorful garden on your slope. When choosing plants, make sure to consider the slopes access to the sun. Put only plants that can withstand the area’s sun exposure. Consider the plant's accessibility for pruning as well.
- Prepare the soil. Does the soil needs walling? If yes, better prepare that first. Put decorative stones, cement, or bricks around the slope to prevent the soil from eroding. This will also prevent any accidental soil erosion while you are planting. If the slope is big enough for a terrace-like garden, then do that. Make sure that every step is wide enough for the plants. Put some walls on every step, too, to keep the soil from going off the hillside.
- Irrigation. One of the biggest problems with a garden on a slope is that plants will not get much water since water speedily runs through the soil. Putting irrigation canals or channels around will solve this problem. To do this, you need to plan how to arrange the plants on the slope. The irrigation system should be ideal for the plant's arrangement.
- Plant. Start planting your chosen varieties as how you want them to be planted. Don’t forget to take care of them regularly. Provide water, sunshine, and fertilizer.
The first months of having your garden on a slope can be the most difficult and busiest months. As your plants get more roots, they also become more independent from you. And if they are already independent, they will need only a little help from you. Finally, you can relax knowing that your erosion-prone slope is less prone to erosion anymore, plus, it has already transformed into a beautiful and well-cultivated garden.
