If your site is fairly hilly or if you have steep slopes in your garden, it is important to stabilize the soil and minimize soil erosion. For this purpose, certain plants are very suitable, which, thanks to the character, structure and growth of their roots, strengthen the soil on the slopes.

The root system forms underground tangles that help bind and reinforce soil stability on slopes. It is attractive and offers a romantic view of the garden in both summer and winter. What also makes the plant attractive is the fact that it is non-toxic and therefore does not pose a danger to pets or even children.

Soil cover against soil erosion: small periwinkle, small periwinkle.

The Vinca Minor shade plant is drought tolerant but toxic to pets.

Unlike juniper, periwinkle is a groundcover that can also tolerate shade. It stays quite small, 7 to 15 cm, and as the name suggests, is also an evergreen. The plant does well in zones 4 to 8, forming a very dense carpet. Another advantage of the beautiful flowering groundcover is that it is very drought tolerant, making it very hardy.

But do not be alarmed by this, as plants can develop deep root systems and thereby compact the soil on slopes. Even if it has to grow sideways, it will still do well on slopes because they cannot disturb the plant. Where hanging branches touch the ground, they form very strong roots that penetrate deep into the soil, trapping it. This is how you behave like a groundcover and stabilize the slope. Golden lilac blooms wonderfully yellow in spring.

Plants for slope stabilization: Japanese Isander, fat man

Its roots also form a cohesive web that strengthens soil structure and minimizes soil erosion on steep slopes. Although the plant produces dainty small white flowers from April to May, it is more visible due to its lush green foliage. The leaves are leathery, rich green, grow profusely and will undoubtedly decorate your garden. Japanese Isander grows in partial shade to shade.
