5 walkable ground covers: lawn alternatives that save water, time and money

Many gardens struggle with parched lawns and rising water bills – but there is a green alternative that needs less upkeep.

Every summer, the same scene returns: brown patches across the lawn, endless watering, mowing and feeding – yet the area still looks tired by the end. More and more gardeners are looking for a living ground cover that can cope with foot traffic, attract insects and use far less water, time and money. This is precisely where walkable ground cover plants come in.

Why a conventional lawn can become an expensive burden

The dream of an evergreen carpet comes at a cost. A traditional lawn demands considerable work, particularly through hot, dry summers. Several factors push up the bill:

• frequent mowing, usually every week during the growing season
• regular fertilising to maintain a rich green colour
• intensive watering during extended dry spells
• petrol or electricity for the lawnmower
• overseeding when areas scorch or become mossy

In addition, many lawns occupy sites that were never suitable: too sunny, too dry, too shady or with heavy soil. The result is intensive maintenance for only moderate results. Ground covers can perform far better in these conditions – especially when they are selected to suit both the site and the intended use.

Choosing the right ground cover saves water, work and frustration over time – while creating a tougher, more vibrant area.

Before choosing: three questions that determine everything

Before putting new plants into the ground, it is worth carrying out a quick site check. Three aspects matter most:

• Sunlight: Full sun, partial shade or mostly shade?
• Soil: Is it heavy and damp, or light and dry?
• Wear: Will it only be walked on occasionally, or used every day by children and dogs?

A thyme carpet works well in sunny, relatively dry spots that are only stepped on from time to time. An area where children play football every day needs tougher options, or even a mix of plants and wood chips.

Top 5 ground covers that withstand foot traffic

1. Zoysia tenuifolia – the dense lawn alternative for heavy use

Known as Mascarene grass, Zoysia tenuifolia is considered an insider choice for heavily used areas. It forms an exceptionally dense cushion that copes well with intensive use.

• high resistance to foot traffic
• far fewer cuts than a conventional lawn (once or twice a year)
• drought-tolerant once well rooted
• ideal for play areas and frequently used paths

Visually, Zoysia resembles a very fine, soft carpet. Anyone who enjoys the uniform look of a lawn can achieve a similar effect here with less work and lower water use.

2. Lippia (Phyla nodiflora) – a low carpet with a flowering bonus

Lippia, also known as a woody verbena species, grows extremely low and covers the ground quickly. Its small flowers attract bees and other insects.

• a tolerant ground cover for repeated walking
• can survive two to three months of drought once established
• creates a closed, low-maintenance carpet
• suitable for sunny to partially shaded positions

For anyone wishing to make their garden more insect-friendly without giving up a walkable surface, Lippia is an excellent choice.

3. Micro-clover – tough and almost self-fertilising

Micro-clover, meaning very small-leaved clover, blends naturally into a green area. It handles foot traffic well and offers one key advantage:

Micro-clover fixes nitrogen from the air and supplies it to the soil – greatly reducing the need for fertiliser.

This quality makes it particularly suitable for family gardens. Children can play on it, the surface remains resilient, and maintenance is largely limited to occasional trimming.

4. Thyme carpets – fragrant, drought-tolerant and bee-friendly

For sunny, relatively low-fertility areas, ground-cover thyme varieties are a good option, including wild thyme (Thymus serpyllum) and woolly thyme. They form dense, low cushions and release an aromatic scent with every step.

• very well suited to dry, stony sites
• tolerates occasional foot traffic, for example around seating areas or beside paths
• attracts bees and wild pollinators
• requires little to no supplementary watering once established

Thyme species cannot cope with heavily used play areas, but they are ideal in courtyards, between stepping stones or around patios.

5. Turquette and Sedum – for extremely dry, poor areas

On truly barren, sandy or stony sites, specialists such as Turquette (Herniaria glabra) and foot-tolerant Sedum species excel. They are especially suited to slopes, stepping stones and joints.

• very low nutrient requirements
• almost no additional water needed after establishment
• cover the ground, preventing erosion and weed growth
• suitable for light to moderate foot traffic only

Anyone who has previously failed to establish a lawn in these “problem areas” will often do much better with these specialist ground covers.

How to replace a lawn with walkable ground cover

Remove the old lawn thoroughly

For the new plants to establish themselves, the old lawn must be removed completely. This can be done, for example, by lifting the turf or using a powered cultivator. Crucially, remove as many root remnants and persistent weeds as possible, otherwise they will hinder the initial establishment.

Prepare the soil properly

Next, loosen the soil to a depth of 15 to 20 centimetres. Adding mature compost improves almost any soil type:

• heavy, clay-rich soils become looser and better aerated
• light, sandy soils retain moisture for longer
• micro-organisms become active, encouraging establishment

Spring and autumn are the best planting periods. Natural rainfall then supports root development, while temperatures are more moderate.

Water correctly during the establishment phase

The first few months determine whether the new carpet becomes reliably robust in the long term. Rather than applying small amounts of water continually, it is better to water deeply but less often. This encourages deeper roots, enabling the plants to cope much better with dry spells later on.

A simple technique helps when weeding: work after rain or watering. Unwanted plants can then be pulled out more easily with their roots, without severely damaging the ground cover.

Everyday care: much easier than a conventional lawn

Once the ground cover is established, maintenance drops considerably. Usually, all that is needed is:

• occasional shaping cuts or infrequent mowing for Zoysia
• checking for isolated dominant weeds
• with micro-clover, perhaps a light trim before flowering if very few flowers are wanted

For intensively used play areas, a combination is worthwhile: micro-clover or robust grasses in the centre, thyme or Sedum around the edges, and wood chips on heavily worn routes. This keeps the surface stable over the long term without placing excessive demands on individual species.

What many people overlook: additional ecological and practical benefits

Alongside reduced work and lower costs, walkable ground covers provide several other advantages. Many species flower, supplying nectar and pollen for insects and contributing to a more lively garden appearance. Instead of a uniform lawn that can often seem still, they create varied carpets with smaller-scale detail.

There is another benefit: ground covers protect soil more effectively against erosion and heavy rain. Rainwater can soak in more readily, reducing surface run-off. This eases pressure on both the drainage system and drainage on the property itself.

Practical examples for different garden types

For small urban courtyards, a mixture of Lippia and thyme around seating areas works well, with a few stepping stones used as paths. In family gardens with plenty of activity, a blend of micro-clover and robust grasses is suitable, while border areas can be planted with Sedum and Turquette.

Allotment gardens also benefit: anyone who does not want to mow every weekend can create heavily used areas with Zoysia, plant the remaining space with foot-tolerant flowering cushions and greatly reduce how often the mower is needed.

Those unfamiliar with botanical names can ask at a garden centre specifically for “walkable ground covers” for sun, partial shade or shade, and check whether they are suitable for gardens used by children and dogs. A quick look at the mature height also helps: very low, cushion-forming species are more appropriate for joints and stepping stones, while slightly taller, springy carpets are better for play areas.
