What are Groundcover Plantings & How Can They Be Useful on Hills?
Groundcovers are typical planted in large groupings, often referred to as mass plantings. These plantings can completely fill in a garden space or slope and “cover the ground,” overtime. These mass plantings help prevent soil and mulch erosion, because of their dense stem and root growth habits.
A key reason that we like groundcover plantings in particular for hills vs. typical plantings with gaps between plants, is that groundcovers are meant to fill in so densely that there is no need to add mulch between the plants once they fill in. For this reason, groundcover plants are considered lower maintenance. Not needing to re-mulch your hillside garden saves time, money and energy cleaning up mulch that tends to wash down the hills during heavy rains.
There are numerous options to choose from when it comes to selecting a great ground cover plant for your hillside and this article will discuss 12 excellent groundcover planting options to consider. When planning out a groundcover design and installation project, we will start by examining options based on the intended look/style, light conditions (how much sun exposure) and the amount of slope within each area of the yard. Slopes, hills, or changes in elevation will present different challenges compared to level ground; These include, erosion control, drainage options, and usage of the area. Although not required, we also often incorporate boulders to mix in texture within a ground-cover plantings in our landscape designs.
The benefits of using a groundcover are numerous, they provide a stabilizing element to the landscape and cutting down on erosion, they proved a vibrant look to any yard, and they proved a great alternative to installing more expensive hardscapes to your landscaping.
