Great alternatives to grass for lawns: climate-proof and zero-maintenance

Different plants to replace lawn grass with

Lawns sure require a lot of work to stay lush and green! Add on a dose of climate change, and clearly lawns aren’t the best choice for many gardens anymore. So what plants should we grow instead of lawn grass? Discover a few easygoing ground cover plants that will succeed in covering vast expanses in emerald tones.

Grass lawns means too many chores

Lawn grass has many drawbacks, especially due to climateA pristine green lawn is a lot of work! There’s all that regular mowing, the occasional moss-removal, sowing of seeds wherever a bare patch appears… Summers get less and less rain, and lawns turn yellow awfully fast as they dry out. With this list of drawbacks in mind, one starts to wonder: what can I replace my lawn grass with?

This is even more relevant if you only visit your holiday house from time to time, and whenever the soil is particularly hard to manage because its too dry or the slope is too abrupt.

Ground cover for full sun

Woolly thyme

This short thyme variety only grows a foot and a half tall for three feet wide (50 cm tall and 1m wide). It’s ideal for dry soil in full sun. Woolly thyme is perfectly suited to dry gardens where sowing grass would only yield a burnt, brown mat. It’s a rugged perennial with hairy gray-green leaves.

Once properly settled in, it can cope with both Summer droughts and Winter frosts. At the end of Spring, this short ground cover shrub is dotted with pink flowers. Nothing to do at all anymore once your woolly thyme has survived a couple years.

Zoysia tenuifolia

Gentle mounds of Korean velvet grassAlso called Korean grass, this no-mow grass forms a dense mat with small mounds and valleys. Never growing any taller than 4 inches (10cm), Zoysia easily copes with treading and footsteps – it actually makes the plant grow more dense. Each plant spreads to about 16 inches (40 cm) across. The plant stays green in all seasons except for Winter. Indeed, if temperatures drop below 32°F (0°C), it turns yellow.

It isn’t finicky in terms of soil, and can make do with any type of growing substrate as long as it drains properly. Once it’s colonized its patch, this type of lawn won’t required any care apart from a once-a-year weeding session. In very hot dry climates, you’ll need to water twice a month during the dry season. In milder climates, no need to water.

Kikuyu

If you live more in Southern parts and don’t get any freezing in Winter, you might want to look into Kikuyu. It’s a plant that appeals to many in warm areas. For instance, in Spain, it’s attracting attention. This easy-to-care-for grass (Kikuyu has the botanical name Pennisetum clandestinum) propagates naturally. You can even mow it once or twice a year if you feel it’s getting a bit too tall.

Ground cover for shade areas

Helxine

Helxine is a charming ground cover plant with small round leaves that are nice and green even without much light. It looks a bit like moss, and grows best in cool, rich soil. It can take moderate foot passage, and usually reaches 4 inches (10 cm) in height. Each plant will grow about 1 foot across (30 cm).

Watch out for the cold, because this cute plant can only cope with freezing down to 14°F (-10°C).

It will gracefully cover the often bare soil at the foot of trees, without suffocating them. Its soft, fluffy texture will espouse the contours of your garden, you can even play around with mounds and the occasional lawn ornament to create interesting landscape features. This perennial will excel in completely shaded areas, and will also fare well in part sun. It’s often included in small urban gardens, alongside shaded ponds, and in Japanese gardens.

Creeping Dichondra

Note, however, that it prefers rich sandy soil. This perennial hates stagnant water, and can’t break through heavy soil. Whether its cool or dry doesn’t matter, but it must always drain perfectly.

Growing to 4 inches in height, a single specimen will cover 1½ square feet (a square about 50 cm wide). It quickly produces a dense, emerald-colored carpet. A drawback in some cases is that it really can’t take a lot of footwear. Best place it in a spot that doesn’t get much foot traffic, and around trees. It will gracefully add a band of lush green along the foot of hedges.

Not much care (just the planting!)

One of the main advantages of ground cover plants is that they require almost no care at all. But this is only true once they’ve conquered their growing space! Right after planting, it’s best to make sure basic care steps are followed so that you may savor a chore-free garden later on. First and foremost, remove weeds, sticks and rocks. Loosen the soil up with a broadfork and rake the soil up before planting. Over the first six months, you’ll have to diligently weed out any seeds that germinate. Do this manually, don’t use any chemicals since these will also affect your ground cover. In this manner, your ground cover plant will dominate and crowd any newcomers out in the long run.

Last of all, whatever you plant, you’ll have to water regularly over the first summer. How often to water depends on the plant species. After that, there’s nearly nothing left to do! Just a short yearly weeding session to pull out tree and shrub seeds, or the eventual mowing to keep growth under control, and you’re done!
