Learning how to plant ground cover is the difference between a clean living carpet and a patchy bed full of weeds. Ground covers are often sold like an easy shortcut: plant a few plugs, wait a season, and bare soil magically disappears. Real yards are not that generous.
Ground cover plants fill in when the site is prepared correctly. That means removing weeds first, matching the plant to the light and soil, spacing plants close enough, watering during establishment, and keeping competition down until the canopy closes. Skip those steps and even the “easy” plants struggle.
Before planting, make sure you have chosen the right plant for the site. A sunny dry strip may need creeping thyme or sedum. A shady bed may need sweet woodruff, barrenwort, ferns, or hosta. A slope may need tougher plants plus erosion control. For plant selection, use our main ground cover plants comparison.
Quick Answer: How to Plant Ground Cover
- Step 1: Remove weeds, turf, roots, rocks, and debris before planting.
- Step 2: Improve soil only for the plant you chose. Do not make dry-loving plants sit in rich wet soil.
- Step 3: Space plugs close enough to fill in before weeds dominate.
- Step 4: Plant in staggered rows for faster visual coverage.
- Step 5: Water consistently during establishment, then adjust to the plant’s mature needs.
- Step 6: Weed early, edge spreading plants, and repair bare spots before they become problems.
Ground Cover Planting at a Glance
| Step | Why It Matters |
|---|---|
| Remove weeds first | Ground covers cannot smother established weeds immediately. |
| Match plant to site | Sun, shade, drainage, and foot traffic decide success. |
| Prepare soil | Roots establish faster in loosened, appropriate soil. |
| Use proper spacing | Closer spacing fills faster and reduces weed pressure. |
| Water during establishment | Even drought-tolerant plants need moisture while rooting. |
| Weed and edge | Maintenance early prevents long-term mess. |
When to Plant Ground Cover
Spring and fall are usually the best times to plant ground cover because temperatures are milder and roots can establish before extreme heat or cold. Summer planting can work with careful watering, but small plugs are easy to lose in hot dry weather.
- Spring: Good for most ground covers, especially in cold-winter regions.
- Fall: Excellent for many perennials because roots establish before summer heat.
- Summer: Riskier; water attention matters more.
- Winter: Usually not ideal unless you garden in a mild climate and the soil is workable.
Step 1: Choose the Right Ground Cover
Planting technique cannot fix the wrong plant. Creeping thyme wants sun and drainage. Sedum wants dry conditions. Sweet woodruff prefers shade. Ice plant needs heat and drainage, plus regional caution. White or blue flowering ground covers need the same site matching as any other plant.
- Creeping thyme for sunny paths, pavers, and dry edges.
- Sedum for dry slopes, rock gardens, and low-water beds.
- Ice plant for hot dry color where it is regionally appropriate.
- White flowering ground covers for clean shade or sun designs.
- Blue flower ground covers for cool color in paths, slopes, and borders.
Step 2: Remove Weeds and Grass Completely
This is the part people want to skip. Do not skip it. Young ground covers do not beat mature weeds, turf roots, bindweed, bermudagrass, nutsedge, or invasive runners by positive thinking.
- Remove existing turf with a sod cutter, shovel, or sheet-mulching plan.
- Dig out perennial weed roots as thoroughly as possible.
- Wait for a flush of new weeds if the area was very weedy, then remove those too.
- Avoid leaving chopped rhizomes in the soil if the weeds spread from fragments.
- Do not plant into an active weed problem and expect the ground cover to win immediately.
Step 3: Prepare the Soil for the Plant You Chose
Not all ground covers want the same soil. This is where many installations go sideways. Compost is useful for some beds, but it is not automatically good for every plant.
| Plant Type | Soil Prep | Avoid |
|---|---|---|
| Dry sun plants | Improve drainage with grit, gravel, or raised planting. | Rich soggy soil. |
| Shade perennials | Add compost where soil is depleted and roots can grow. | Smothering tree roots with deep soil. |
| Moisture lovers | Improve organic matter and keep even moisture. | Dry, hot, reflective sites. |
| Walkway plants | Create loose soil pockets between stones. | Compacted gravel with no root zone. |
Step 4: Decide Between Plugs, Pots, Seeds, Cuttings, or Mats
There is no single best planting form. The right choice depends on budget, area size, patience, and how fast you want coverage.
| Planting Form | Best For | Trade-Off |
|---|---|---|
| Plugs | Most ground cover projects | Good balance of cost and speed. |
| Potted plants | Small beds and fast visual impact | More expensive. |
| Seeds | Budget planting and large areas | Slow and vulnerable to weeds. |
| Cuttings | Sedum, repairs, propagation | Needs patience and careful moisture. |
| Mats | Sedum carpets and fast coverage | Higher upfront cost. |
If you are using sedum mats instead of plugs, the sedum mat installation walkthrough covers soil depth, fitting tiles, trimming edges, and watering until the mat roots into the base.
Step 5: Space Ground Cover Plants Correctly
Spacing decides how quickly the planting fills in and how much weeding you do before it closes. Closer spacing costs more upfront but often saves time and frustration.
| Spacing | Best For | Result |
|---|---|---|
| 6 inches apart | Tiny plugs and high-visibility areas | Fastest fill, highest cost. |
| 8 to 12 inches apart | Most plug plantings | Good balance. |
| 12 to 18 inches apart | Larger perennials and budget projects | Slower fill and more weeding. |
| 18 to 36 inches apart | Shrubby ground covers and large spreaders | Longer establishment window. |
Step 6: Plant in Staggered Rows
A staggered triangular pattern fills more evenly than straight rows. It also looks more natural and reduces obvious empty lanes between plants.
- Lay plants out before digging.
- Stagger the second row so plants sit between the plants in the first row.
- Keep spacing consistent unless the bed shape requires adjustment.
- Step back and check the pattern before planting.
- Dig holes only as deep as the root ball.
- Set crowns level with the soil surface.
- Firm soil gently around roots.
Make Ground Cover Planting Easier
A soil knife, garden kneeler, measuring tape, and gentle watering wand make spacing and planting plugs much easier.
Step 7: Mulch Between Young Plants
A light mulch layer helps reduce weeds while ground covers fill in. The key word is light. Thick mulch can bury crowns, smother creeping stems, and slow the spread you are trying to encourage.
- Use fine mulch in shade beds: Keep it thin and away from crowns.
- Use gravel around dry-site plants: Sedum, thyme, and ice plant often prefer mineral mulch.
- Avoid mulch mountains: Do not bury low stems or new shoots.
- Refresh carefully: Once the ground cover fills in, you may not need much mulch at all.
Step 8: Water During Establishment
New ground covers need water while roots establish, even if the mature plant is drought tolerant. Watering should keep the root zone from drying out completely without making the bed soggy.
- First 2 weeks: Check soil often and water when the top layer begins to dry.
- Weeks 3 to 8: Water less often but deeper as roots grow.
- After establishment: Match watering to the plant’s mature needs.
- On slopes: Use shorter watering cycles to prevent runoff.
- During heat waves: New plugs may need extra protection and water.
How to Plant Ground Cover on a Slope
Slopes need more planning because water, mulch, seed, and soil can move downhill before plants establish. Use plants that match the slope’s sun and moisture, then stabilize the area while roots take hold.
- Remove weeds and turf thoroughly.
- Work across the slope, not straight up and down.
- Use staggered planting to slow runoff visually and physically.
- Choose plugs or mats instead of seed for faster stabilization.
- Use jute netting, erosion fabric, rocks, or terraces where needed.
- Water gently so soil does not wash away.
- Inspect after heavy rain and replant washed-out areas quickly.
Common Ground Cover Planting Mistakes
- Planting into weeds: Ground cover is not instant weed control.
- Spacing too far apart: Cheap at planting time, expensive in weeding time.
- Using the wrong plant for the site: Sun, shade, drainage, and traffic matter.
- Overmulching: Thick mulch can smother low-growing plants.
- Overwatering dry-site plants: Sedum, thyme, and ice plant hate soggy soil.
- Ignoring edges: Spreading plants need boundaries near lawn and paths.
- Expecting no maintenance: Ground covers are low maintenance after establishment, not zero maintenance.
Want Help Installing Ground Cover Correctly?
Large ground cover projects can involve turf removal, grading, drainage, soil prep, erosion control, and plant selection. If the area is a slope, a front-yard lawn replacement, or a high-visibility path, it may be worth getting help before buying hundreds of plugs.

Final Takeaway
Ground cover planting works when you treat establishment as the real project. Remove weeds first, prepare the soil for the plant you chose, space plugs close enough, plant in staggered rows, water carefully, and keep the bed clean until the plants close in.
Once established, ground covers can reduce mulch use, soften hardscape, suppress some weeds, and make difficult yard areas look intentional. The payoff is real, but the clean carpet starts with boring prep work.
Frequently Asked Questions About Planting Ground Cover
How do you plant ground cover?
Remove weeds and turf, prepare the soil for the plant you chose, space plugs correctly, plant in staggered rows, water during establishment, mulch lightly, and weed until the ground cover fills in.
How far apart should ground cover plants be planted?
Small plugs are often planted 6 to 12 inches apart. Larger ground covers may be spaced 12 to 36 inches apart. Closer spacing fills faster and reduces weeding.
When is the best time to plant ground cover?
Spring and fall are usually best because temperatures are milder and roots can establish before heat or cold stress. Summer planting requires more careful watering.
Can you plant ground cover over grass?
It is usually better to remove grass first. Planting ground cover directly into turf creates competition for water, nutrients, and light.
Should you mulch around ground cover?
Yes, but lightly. Mulch helps reduce weeds while plants establish, but thick mulch can bury crowns or smother creeping stems.
How long does ground cover take to fill in?
Many ground covers take one to three growing seasons to fill in, depending on plant type, spacing, soil, water, and weed control.
Can you plant ground cover on a slope?
Yes, but slopes need erosion control while plants establish. Use plugs or mats, stagger planting, water gently, and consider jute netting or rocks on steeper slopes.
Do ground covers stop weeds?
Ground covers help suppress weeds after they fill in, but they do not kill established weeds immediately. Weed removal before planting is essential.
Should I use seeds or plugs for ground cover?
Plugs are more reliable and fill faster. Seeds are cheaper for large areas but slower, more uneven, and more vulnerable to weeds.
How often should I water new ground cover?
Water often enough to keep the root zone lightly moist during establishment. After plants root, reduce watering based on the needs of the specific ground cover.
