Great, Green, Growing, Groundcovers!
May 15th, 2012Groundcovers have been a staple in home and commercial landscapes for many years. This group of low-growing plants enhance almost any bed’s appearance, providing texture variation and color contrast for surrounding plants. Their beauty and aesthetic value isn’t their only function. Groundcover can help to cut down on weed growth in some areas, as well as aiding in moisture retention for trees and shrubs. A thick stand of groundcover can even reduce your annual maintenance costs, as it can substitute for annual mulching after it is established. There are also instances where turfgrasses cannot survive because of the limited availability of sunlight, which can be the ideal situation for some groundcovers.
There are hundreds of plants that can be used for groundcover. Selecting the best variety is key. There isn’t one perfect groundcover, but many have advantages and disadvantages. Examining your site, your maintenance implications, and function of use is essential to finding a groundcover that will be great, instead of one that will make you growl. Be sure to know what growing zone you live in to make the best selection for your landscape. Here are just a few of the popular varieties that are used in our area.
English Ivy (Hedera helix)
English Ivy is a widely-used, very traditional, evergreen groundcover. It establishes fairly easy and is a vigorous grower. Being a quick-grower can be its greatest disadvantage as well. Ivy will creep up structures, trees, and surrounding items, causing damage to surfaces at times. It’s a great choice, but carries a substantial consideration of maintenance, as it will need trimmed off of surrounding items several times a year. It does very well in low-light situations, can can also grow in partially-sunny areas as well.
Pachysandra (Pachysandra terminalis)
Another traditional ground cover is Pachysandra. This variety can be somewhat difficult to establish, but is a great addition to landscapes, because it is not a climber, and won’t scale walls and trees. Pachysandra develops a small white bloom in the spring, and is also an evergreen plant that will provide color to your beds year-round. One of the major disadvantages to Pachysandra is its likelihood of insect and disease damage. If this is the variety you choose, please know that there will need to be an insect and disease management program required to address concerns 4-5 times per growing season. It will tolerate shady and semi-shady situations, which gives it more usability than ivy.
Periwinkle (Vinca minor)
Periwinkle (Myrtle) is one of our favorite ground covers to install. This plant will tolerate both shady and sunny areas. It establishes at a moderate rate, is evergreen, and develops beautiful flowers in spring but will re-bloom throughout the summer. It is also not a climber, making it easier to manage in a landscape. It can develop some issues with disease when high night-time temperatures and abundant humidity is present, but overall is a pretty durable plant.
Plumbago (Ceratostigma plumbaginoides)
Plumbago is also another terrific choice. This plant will flower in mid-summer with these beautiful blue flowers. In late summer, the foliage will turn a gorgeous coppery-bronze before shedding it’s foliage in fall. It typically prefers full sun, but can adapt into shaded areas as well. There are a few diseases that can damage the leaves on the plant, but it is at most times very resilient.
Choosing the correct ground cover is not the only consideration. A plant’s success is heavily impacted by it’s installation and maintenance, particularly while it is attempting to establish. Beds that are determined as the area of installation need to be properly prepared. The soil should be tilled to 4-6″ so the soil will not be too compacted for the young, expanding roots. Testing the soil and adding fertilizer and organic compost provides a nutrient-rich environment for the plants to mature. Proper spacing is critical as well as a light cover of mulch to help moisture to retain. Ground cover plants may take a year or more to mature to the point that they can tolerate periods of drought, so watering on a regular basis is essential. Managing weeds in your landscape beds can be somewhat problematic until the plants fill-in. Pre-emergent weed controls are helpful to reduce hand-pulling in these areas. If you use a local landscaper to install these plants, make sure they perform these recommendations as part of the installation, or you could be throwing away your investment.
Good luck growing great, green, ground cover!
