It’s not just about the fresh lemony scent, but the endless ways you can use it – teas, cooking, and even natural remedies. Ever find yourself wishing you had more of it? Well, here’s the good news: propagating lemon balm from cuttings it’s super easy and fun. So, let’s dive into how you can do this, along with a few tricks I’ve picked up over the years.
You know what’s cool? The methods you’ll use to propagate lemon balm can be just as handy for other members of the mint family. If you’re curious, feel free to check out my guide on mint propagation.

Get to Know Lemon Balm: 5 Things You Should Know
Perennial Herb with Multiple Harvests
Lemon balm, a perennial herb native to Southern Europe and parts of the Middle East, is a reliable addition to any herb garden. As a perennial, it returns year after year, providing you with a steady supply of aromatic leaves. What’s even better is that you can harvest these leaves multiple times throughout the growing season, ensuring a continuous supply of fresh, lemony goodness. It’s the perfect choice if you’re looking for an easy-to-care-for plant that keeps on giving.
Rapid Growth
This herb isn’t shy about growing – fast and wide. If you plan to let it roam freely in your garden, keep an eye on it, or it might just take over. Personally, I prefer growing lemon balm in pots to prevent it from taking over other plants.
Low Maintenance
One of the things I love about lemon balm is how little fuss it needs. Once it’s settled in, you can almost forget about it. It’s the kind of plant that just does its thing, leaving you to enjoy its benefits with minimal effort.
Thrives in Various Conditions
Whether it’s basking in full sun or chilling in partial shade, lemon balm doesn’t mind. It’s also fantastic indoors – so if you have a sunny window, you’re in luck. You’ll get to enjoy its scent and harvest the leaves throughout the year.
Versatile Uses and Health Benefits
Lemon balm isn’t just about taste; it’s also known for its calming effects, helping to reduce stress and anxiety, promote sleep, and even support digestion. This makes lemon balm a valuable addition to any garden or home.
The Best Time to Take Lemon Balm Cuttings
Timing can make all the difference when you’re propagating plants. From my experience, the best time to take cuttings from lemon balm is late spring or early summer. The plants are thriving during this period, making it the ideal time to give propagation a go. I like to do it in the early morning, when the plants are still cool and fresh from the night – it seems to help them bounce back quicker.
Taking Lemon Balm Cuttings
So, you’ve got your timing down. Now, let’s go over how to take those cuttings properly:
Choosing the Right Stem
Look for healthy, green, non-flowered stems about 3 to 6 inches (7 to 15 cm) long. Aim for sturdy stems that are free from any signs of disease or damage. This gives your cuttings the best shot at rooting successfully.
Focusing on the Nodes
The node is the part of the stem where the leaves and side shoots sprout. This is where the magic happens – roots are most likely to form here. So, make sure you cut just below a node. Not sure where the node is? Look for a small bump or swelling on the stem where the leaves are attached – that’s your node.
Using the Right Tools
Always work with clean, sharp scissors or pruning shears. A clean cut reduces the risk of infection, and sharp tools make for a precise cut that’s better for the plant.
Avoid Over-Harvesting
When taking cuttings, it’s important not to over-harvest. A good rule of thumb is to take no more than one-third of the plant at a time. This ensures the parent plant remains strong and continues to thrive.
Preparing the Cuttings for Rooting
After you’ve picked your stems, it’s time to prepare them for rooting:
Start by removing the lower leaves from the bottom of the stem, leaving a couple of small, healthy leaves at the top. This helps the cutting focus on growing roots instead of supporting extra leaves. If the remaining leaves are large, I sometimes trim them in half to reduce water loss. It’s a small step, but it really helps keep the cutting hydrated.
Tip: Don’t toss those leaves! You can dry them and use them later in teas or as a garnish for dishes.
Rooting Lemon Balm Cuttings in Water
Now for the part that always feels a bit magical – getting those cuttings to root in water. While there are generally two main methods for propagating cuttings – rooting in water or planting directly in soil – I’ve found that cuttings tend to root faster using the water method.
To start, choose a small jar or glass, and fill it with clean water. Make sure the container is tall enough to support the cuttings and allow the bottom nodes to be submerged.
Place your prepared cuttings into the water, ensuring the bottom nodes are fully submerged. The nodes are where the roots will begin to form. It’s best to place the jar in a spot with indirect sunlight – too much direct light can heat up the water and harm the cuttings.

Keep an eye on the water level to ensure the nodes stay submerged. Change the water every few days to keep it fresh and oxygenated, which helps prevent mold and encourages healthy root growth. Within a couple of weeks – typically 1 to 2 weeks – you should start to see roots forming.
Transferring the Cuttings to Soil
Once the roots on your cuttings have grown to about 1 to 2 inches long (2.5 to 5 cm), it’s time to plant them in soil.
Prepare the Pots
Get small pots ready – about 6 to 8 inches (15 to 20 cm) in diameter is ideal for 3 to 4 cuttings. Ensure the pots have drainage holes at the bottom to avoid water buildup and prevent root rot. Fill the pots with a light, well-draining mix, such as a blend of peat and perlite, or a seed-starting mix.
Planting the Cuttings
Make small holes in the soil with your finger or a pencil, spaced evenly apart. Carefully place each cutting into its own hole, making sure the roots are covered and the stems are supported. Gently press the soil around each cutting to ensure it makes good contact.
Watering
After planting, water the soil lightly to help settle the roots, but be cautious not to overwater. The young roots are still sensitive to too much moisture.
Placement
Position the potted cuttings in a location with indirect light and maintain the soil consistently moist, but not waterlogged. Over the next few weeks, the cuttings should begin to establish themselves in their new environment. When you notice new leaves starting to emerge, it’s a good sign that the roots have adapted well and the plant is on its way to thriving.
Caring for Your New Lemon Balm Plants
Watering
In the first few weeks after transplanting, it’s crucial to keep the soil consistently moist, but don’t overdo it. Once the plants settle in, they won’t need as much attention. Still, I like to give them regular water, especially during dry spells. A little extra care at this stage really pays off down the road.
Pruning and Harvesting
Over time, I’ve learned that lemon balm really benefits from regular pruning. Trimming it every few weeks keeps the plant looking neat and encourages fresh, vigorous growth. Plus, regular harvesting helps the plant grow even stronger and fuller. It’s a win-win – more lemon balm for you, and a healthier, happier plant.
Dealing with Pests and Diseases
Lemon balm is generally a tough plant, but sometimes aphids can become an issue, especially on the tender new growth. These tiny pests suck the sap from the leaves, which can weaken the plant and cause the leaves to curl or become distorted. It’s frustrating, but I’ve found that a quick spray with mild soapy water usually keeps them under control.
In humid conditions, I’ve also noticed that powdery mildew can sometimes develop. To prevent this, I make sure there’s good air circulation around the plant and try not to get the leaves too wet when watering.
