What is Bugleweed?
Ajuga reptans, or bugleweed, is a hardy perennial that grows in Europe but is now a common plant in gardens all over the world. In my experience, bugleweed is unique because it grows by sending out runners, or stolons, that root wherever they touch soil. Over time, these runners form a thick mat. This is a great bugleweed ground cover because it fills in gaps quickly. The leaves are oval and shiny, and they can be any color from deep green to burgundy, with creamy edges for extra interest. In late spring, you’ll see those lovely flowering spikes grow 6 to 8 inches tall, with groups of blue, purple, or pink flowers on top that attract bees and butterflies. I put it in my own backyard under some old oaks, and it just weaves through the mulch like it’s on a mission to cover every inch.
What Are the Benefits of Bugleweed Ground Cover in Your Garden?
I’ve told a lot of clients to use bugleweed ground cover over the years because it’s a workhorse that solves problems without making new ones. First of all, its thick growth chokes out weeds before they can take root, so you don’t have to pull them up all the time. Bugleweed’s rooting runners help keep soil in place during heavy rains on slopes and hills, which helps control erosion. It can grow in a lot of shade, like under trees or along north-facing walls, where grass has trouble. And it’s easy to care for: once it’s grown, it doesn’t need much water or fertilizer, so it’s great for gardeners who forget things or don’t have a lot of time. I’ve used bugleweed ground cover in my landscaping projects. It adds color all year long in milder climates because its leaves stay green. Plus, it’s deer-resistant, which is a plus in suburban yards. It also doesn’t spread too much in most places, but you should keep an eye on it so it doesn’t end up in places you don’t want it to.
Seasonal Care Calendar
To keep your bugleweed ground cover looking its best through the seasons, I’ve put together this simple calendar based on what I’ve done in my own gardens and client sites. It’s all about timing those small tasks for maximum impact.
Season | Care Tasks |
Spring | Divide overcrowded clumps; plant new starts; lightly fertilize; mulch around plants to retain moisture; watch for emerging pests. |
Summer | Water during dry spells; trim back spent flower spikes; control spread by edging; monitor for heat stress in sunny spots. |
Fall | Clean up fallen leaves; divide if needed; apply a light mulch layer for winter protection; reduce watering as growth slows. |
Winter | Minimal care; protect from heavy snow if in cold zones by avoiding foot traffic; prune any damaged foliage in late winter. |

How To Plant And Care For Bugleweed
It’s not hard to plant and care for bugleweed; it’s more like giving a good friend a place to stay. I’ve helped dozens of homeowners grow healthy bugleweed ground cover over the years, and it all comes down to these simple steps. I’ll show you how to do each one, based on my own mistakes and successes, so you can get it right the first time.
Step 1: Pick the Right Place to Plant
The first step to a happy bugleweed is to find a place that it likes. I have found that bugleweed ground cover does best in partial to full shade, where it can spread without getting burned by the sun. Try to find places under trees, along shaded edges, or in those hard-to-reach spots where other plants flop. It can handle some morning sun, but too much heat in the afternoon can make the leaves fade or slow down growth. Bugleweed likes ground that is always damp but not too wet. Check the moisture level in your soil. In my experience, staying out of full sun in hot places keeps it from wilting, and staying away from bone-dry places keeps it from getting thinner. Walk around your yard at different times of the day to see how the light changes. Keep in mind that bugleweed is forgiving but grows best where it doesn’t have to compete with tree roots for water.
Step 2: Make the soil loose and able to drain well.
Prepare the soil before you plant. It’s the base for healthy bugleweed growth. I always start by using a garden fork to loosen the top 6 to 8 inches and break up clumps so that the runners can easily root. To keep bugleweed from getting root rot, it needs soil that drains well. If your yard has heavy clay like mine did years ago, mix in organic matter like compost or leaf mold. A quick soil test from your local extension can help you find the right pH level, which should be between 5.5 and 7.0. I’ve added peat moss to sandy soils to help them hold moisture better, and it makes a huge difference in how quickly they grow. Get rid of weeds and trash first. Bugleweed will outcompete them later, but it needs a clean start.
Step 3: Putting plants in the right places to cover the ground
Spacing is very important to get that thick carpet look without making it too crowded. I recommend planting bugleweed starts 12 to 18 inches apart. They’ll fill in in a season or two because they spread so quickly. For faster coverage in bigger areas, go tighter at 8–12 inches, but keep an eye out for competition. This spacing lets air flow through bugleweed ground cover beds, which keeps mildew from growing and makes sure the mat is thick. Think about how big the plants will get; each one will eventually cover a few square feet. I learned the hard way that planting things too close together can make them patchy because they shade each other out. So, at first, give them some space.
Step 4: How to Plant Bugleweed the Right Way
Dig holes that are about 4 to 6 inches deep for most starts. This is the same depth as the root ball. Put the bugleweed in the hole, spreading the roots out gently, and then fill the hole back in with soil, pressing it down to get rid of air pockets. Water right away to settle everything down. I like to plant in the spring or fall when the weather is mild. This gives the roots time to get used to their new home before the weather gets too hot or too cold. If the roots of the bugleweed ground cover are tangled, you can tease them apart. After that, lightly mulch with bark or compost to keep weeds down and moisture in. I’ve seen this simple step double the survival rate in new beds.
Step 5: Watering While the Plants Are Growing
Watering is very important in the first few weeks. Try to keep the soil evenly moist, with about an inch of water per week, or more if it’s dry. I use a soaker hose for bugleweed ground cover so that the leaves don’t get wet, which can lead to fungus. Bugleweed can handle dry weather once it has grown for 4 to 6 weeks, but don’t let it completely dry out when it’s hot. I’ve seen that watering my gardens regularly at the beginning makes the leaves thicker later on. Put your finger in the soil to see if the top inch is dry. If it is, it’s time to water. You won’t have to water as often as you used to, maybe every 10 to 14 days.
Step 6: Give them food and light fertilizer.
Bugleweed doesn’t need a lot of food, but a little extra helps a lot. In the spring, I use a balanced, slow-release fertilizer, like a 10-10-10 granular type, at half strength to keep the plants from growing too quickly and becoming more vulnerable to pests. Compost top-dressing works great for bugleweed ground cover in soils that don’t have a lot of nutrients. I’ve done it every year and seen bright colors as a result. Don’t fertilize in the fall so that plants can get ready for winter. Look for signs of deficiency, like yellowing leaves, and only make small changes. In my experience, too much fertilizer can make stems weak and floppy.
Step 7: Trimming and controlling the spread
After flowering, use shears to cut off the spent blooms of bugleweed, just above the leaves. This will keep the plant looking nice. This makes the plants grow thicker. To keep bugleweed from spreading, I put up barriers like plastic or metal strips buried 4 inches deep around the edges of the beds. When runners hit them, they turn back. Every few years, lift sections of crowded areas to make them less crowded. Regular trimming keeps it from taking over lawns in my yard and keeps the mat healthy and even.
Step 8: Taking care of pests, diseases, and uneven growth
There are some pests, like slugs or aphids, that can harm bugleweed, but it is tough. I pick slugs by hand at night or use organic baits. If you have diseases like crown rot because of bad drainage, make the soil better as needed. Too much shade or competition can cause patchy growth. To fix this, cut back on overhead branches or split up clumps. I take care of bugleweed ground cover, and neem oil sprays work on small infestations without using strong chemicals. Be on the lookout for problems in humid weather.
Step 9: Taking care of and maintaining long-term bugleweed ground cover
In the long run, bugleweed ground cover is worth the little work it takes to keep it looking good all year. Every three to four years, divide the plants to keep them healthy. Every year, put mulch around them to keep weeds away. In sensitive ecosystems, keep an eye on them to see if they spread too much. In colder areas, it might die back, but it will come back in the spring. From my years of experience, it stays a low-maintenance staple with regular but light care, like weeding and watering every now and then.
The Best Types of Bugleweed
I have tried a few different kinds of bugleweed, and each one is different in its own way. The leaves of “Chocolate Chip” are narrow and bronze-purple, which gives it a beautiful chocolatey color in the shade. ‘Burgundy Glow’ has leaves that are pink, white, and green, which makes dark areas look brighter. ‘Black Scallop’ has deeply scalloped, almost black leaves that look great with blue flowers. This gives it a classic look. “Catlin’s Giant” is bigger, has bolder leaves, and taller spikes, making it great for bigger areas. And “Golden Glow” has chartreuse edges that shine in the dark. Mixing different types of bugleweed in ground cover designs adds texture and interest without any extra work.
Things Newbies Shouldn't Do
There are some common mistakes that new gardeners make when growing bugleweed. When you plant too many plants too close together, they compete with each other and create thin spots. Make sure to give them enough space, as I said. If you don’t fix soggy soil, it will cause root rot. If you don’t control bugleweed ground cover, it can become a bully and take over lawns or flower beds. So, put up edges early. Weeds will grow if you don’t use mulch, and fungus will grow if you water established plants too much. I’ve learned that starting small and watching things grow keeps most problems from happening when I help friends fix these.
Ideas for landscaping and how to use them
In creative landscaping, bugleweed ground cover looks great. Plant it under old trees where grass won’t grow. This will make a natural forest floor. It keeps soil from sliding down hills and adds color. Put it along the edges of paths to make them look softer and more like trees. It grows between rocks in rock gardens to look wild. Bugleweed is a good alternative to grass in shady yards because it doesn’t need to be mowed or watered as much. I’ve made beds with it and hostas or ferns to add texture, or I’ve let it spill over retaining walls to make it look like it’s cascading. It can also be used in containers, where it can hang over the edges.
How to Get Thicker and Healthier Coverage
Here are some tips from my toolbox for getting that soft bugleweed ground cover. For a natural flow, plant in groups of odd numbers. After it rains, gently press down on loose runners to help them root. Once a month, a deep soak is better than watering often but not deeply. Plant spring bulbs next to them; they will easily poke through the mat. To get more color, shear the whole bed in early spring to make new growth. Don’t walk on new plants; it compacts the soil. And if the leaves start to look dull, a foliar spray made from seaweed extract brings them back to life. I’ve used this on client projects with great results.
Ways to Propagate (Division and Runners)
It’s easy and cheap to grow bugleweed. To divide, in the spring or fall, dig up a mature clump and carefully pull apart sections that still have roots. Replant right away, with 12 inches between each plant, and give them a lot of water. This is how I’ve split one plant into five, filling in gaps quickly. For runners, cut 4 to 6 inch pieces with nodes, press them into wet soil, and use wire to hold them down if you need to. Keep it in the shade and wet until it roots, which should take about two to three weeks. This method makes bugleweed ground cover beds grow much bigger without having to buy more starts.
In conclusion, bugleweed ground cover is a simple and dependable choice for any gardener who wants a beautiful garden that doesn’t need much care. It’s been a mainstay in my gardens for years, turning problem areas into highlights. It spreads quickly, tolerates shade, and doesn’t need much care. Try it out; you’ll be amazed at how much easier it makes gardening.
FAQs –
1. How quickly does bugleweed grow in a normal garden?
Under the right conditions, bugleweed can grow 6 to 12 inches a year, but I’ve seen it cover a 10-square-foot area in two seasons with plenty of moisture and shade. Soil quality and climate are two things that matter. In my milder zone, runners root faster in loamy soil than in clay. To speed it up, encourage by burying tips, but keep an eye on it to make sure it doesn’t go too far.

3. Can people walk on bugleweed like they can on grass?
Bugleweed can handle light foot traffic, but it isn’t as tough as grass for heavy use. It can handle some walking on paths I’ve made, even though it gets a little bruised and then heals. For areas with a lot of foot traffic, use stepping stones to protect the mat. In shaded areas with little traffic, it’s better.
4. What other plants go well with bugleweed?
Hostas, astilbes, and ferns go well with bugleweed because they add height and texture to its low profile. It lets spring bulbs like daffodils grow through it without any problems. To keep competition down, stay away from aggressive spreaders like mint. This mix makes layered, low-maintenance beauty in shade gardens.
5. How can I bring back bugleweed patches that are getting thinner?
Thinning is often a sign that there isn’t enough light or nutrients. I’ve brought patches back to life by splitting them up and replanting healthy parts, adding compost, and making sure the moisture is even. If it’s too shady, trim back the branches above to let in more light. Patience pays off; these changes will make it bounce back in a season.
6. Does bugleweed bring animals to the garden?
Of course, its flowers attract bees and butterflies, which helps pollination. I’ve also seen more hummingbirds in my yards. Deer usually don’t eat it because of its texture, so it’s good for wildlife but not a buffet. It’s a quiet way to help ecosystems.
7. Can I grow bugleweed in pots?
Yes, bugleweed grows well in pots on patios or balconies. Mix that drains well, give it some shade, and water it often. I’ve put varieties like “Chocolate Chip” in pots so they can trail over the edges in a cute way. For year-round green, keep your plants inside during the winter in cold areas.
8. How do you get rid of bugleweed if it grows too much?
If bugleweed starts to grow, use a shovel to dig it up in pieces, making sure to get all the roots so it doesn’t grow back. I’ve cleared areas by putting down black plastic in the summer heat. Pull runners by hand for small areas. It’s persistent, so persistence wins. Follow up with those who are behind.
