Transplanting lemon balm is best done in early spring before the plant puts out its full flush of new growth. If you’ve ever wondered how to transplant lemon balm, you’re in the right place. This hardy herb spreads quickly, so moving it to a better spot or dividing it keeps your garden tidy and your plant healthy. Let’s walk through the simple steps together.
Lemon balm is a mint family member, which means it grows like crazy. It can take over a garden bed if you let it. But transplanting is easy and rewarding. You’ll get more plants for free, and your lemon balm will thrive in its new home.
Why Transplant Lemon Balm?
You might need to transplant lemon balm for several reasons. Maybe it’s outgrowing its spot. Or you want to share it with a friend. Sometimes the soil gets tired, or the plant becomes too crowded. Moving it gives it fresh soil and space to grow.
Transplanting also helps control its spread. Lemon balm sends out runners underground. If you don’t keep it in check, it can invade other plants. By moving it to a contained area or a pot, you keep your garden organized.
Another reason is to rejuvenate an old plant. After a few years, lemon balm can get woody and less productive. Digging it up, dividing it, and replanting the healthiest parts gives it new life.
How To Transplant Lemon Balm
Now let’s get into the main event. Here is the step-by-step guide on how to transplant lemon balm. Follow these steps, and you’ll have success every time.
Step 1: Choose The Right Time
Early spring is best, just as new growth starts. The soil is cool and moist, which helps roots settle in. You can also transplant in early fall, but give the plant at least six weeks before the first frost. Avoid hot summer days—the stress can kill the plant.
If you must move it in summer, do it on a cloudy day or in the evening. Water deeply before and after transplanting to reduce shock.
Step 2: Prepare The New Location
Lemon balm likes full sun to partial shade. It grows well in most soils but prefers rich, well-draining ground. Dig a hole twice as wide as the root ball and just as deep. Mix in some compost or aged manure to give it a nutrient boost.
If you’re planting in a pot, choose one at least 12 inches wide with drainage holes. Use a quality potting mix. Lemon balm spreads quickly in containers too, so don’t go too small.
Step 3: Water The Plant Well
Water your lemon balm thoroughly the day before transplanting. This makes the soil stick to the roots and reduces stress. It also makes digging easier. Give it a good soak, not just a sprinkle.
If the plant is in a pot, water it until water runs out the bottom. For garden plants, use a hose or watering can to saturate the area around the base.
Step 4: Dig Up The Lemon Balm
Use a garden fork or shovel to loosen the soil around the plant. Start about 6 inches away from the base to avoid cutting too many roots. Gently lift the plant from the ground. Shake off excess soil so you can see the roots.
If the plant is large, you might need to dig a bigger circle. Take your time. Damaging the roots too much can set the plant back. For established clumps, you can divide them at this stage.
Step 5: Divide If Needed
Lemon balm grows in clumps that are easy to split. Look for natural divisions where the stems separate. Use a sharp knife or your hands to pull apart the clump. Each division should have several roots and at least one stem.
Dividing is a great way to get more plants. You can replant the divisions in different spots or give them away. Make sure each piece has enough roots to survive.
Step 6: Plant In The New Spot
Place the lemon balm in the prepared hole. The top of the root ball should be level with the soil surface. Backfill with soil and press down gently to remove air pockets. Water thoroughly after planting.
Space multiple plants about 18 inches apart. This gives them room to spread without crowding. If you’re using a pot, fill around the roots with potting mix and water well.
Step 7: Mulch And Care
Apply a 2-inch layer of mulch around the base. This keeps the soil moist and cool. It also suppresses weeds. Use organic mulch like straw, bark, or compost. Keep the mulch away from the stem to prevent rot.
Water regularly for the first few weeks. Lemon balm likes consistent moisture but not soggy soil. Once established, it’s quite drought-tolerant. Check the soil every few days and water when the top inch feels dry.
Common Mistakes To Avoid
Even experienced gardeners make mistakes when transplanting lemon balm. Here are a few to watch out for.
Transplanting Too Late In The Season
If you wait until summer, the heat can stress the plant. Leaves may wilt or turn yellow. The roots struggle to establish. Stick to early spring or early fall for best results.
Not Watering Enough After Transplant
Newly transplanted lemon balm needs extra water. The roots are damaged and can’t take up moisture well. Keep the soil consistently damp for the first two weeks. Don’t let it dry out completely.
Planting Too Deep
Burying the stem can cause rot. The crown of the plant should be at soil level. If you plant too deep, the stem may decay. If too shallow, roots dry out. Level is key.
Ignoring Spread Potential
Lemon balm spreads aggressively. If you don’t want it taking over, plant it in a container or use a root barrier. You can also trim back runners regularly. Some gardeners sink a pot into the ground to contain the roots.
Aftercare For Transplanted Lemon Balm
Once your lemon balm is in its new home, give it some TLC. Here’s what to do in the weeks after transplanting.
Watering Schedule
Water deeply once or twice a week, depending on weather. In hot spells, you might need to water more often. Check the soil moisture with your finger. If it’s dry an inch down, it’s time to water.
Reduce watering as the plant establishes. After a month, lemon balm can handle drier conditions. But don’t let it wilt for long periods.
Fertilizing
Lemon balm doesn’t need much fertilizer. A light application of balanced organic fertilizer in spring is enough. Too much nitrogen makes leaves soft and less flavorful. Compost worked into the soil at planting time provides all the nutrients needed.
If you notice yellowing leaves, it might be a sign of nutrient deficiency. Add a weak liquid fertilizer or top-dress with compost.
Pruning And Harvesting
You can start harvesting leaves once the plant has settled in, about 4-6 weeks after transplanting. Snip leaves from the top to encourage bushy growth. Regular harvesting keeps the plant compact and productive.
Prune back flower stalks to prevent the plant from going to seed. This also keeps the leaves flavorful. If you want to save seeds, let a few flowers bloom and dry.
Winter Protection
In cold climates, lemon balm dies back to the ground in winter. Mulch heavily after the first frost to protect the roots. In spring, new growth will emerge from the base. In mild climates, it stays evergreen year-round.
If you’re growing in pots, move them to a sheltered spot or indoors for winter. Container plants are more vulnerable to freezing.
Growing Lemon Balm In Containers
Transplanting lemon balm into a pot is a smart move. It controls the spread and lets you move the plant around. Here’s how to do it right.
Choosing A Pot
Use a container at least 12 inches wide and deep. Bigger is better because lemon balm has a vigorous root system. Make sure the pot has drainage holes to prevent waterlogging.
Terracotta pots work well because they breathe. Plastic pots retain moisture longer. Choose based on your climate and watering habits.
Potting Mix
Use a high-quality potting mix that drains well. Add perlite or sand for extra drainage. Avoid garden soil—it compacts in pots and can harbor pests. Mix in some compost for nutrients.
Fill the pot about two-thirds full, place the plant, then add more mix. Water thoroughly after planting to settle the soil.
Maintenance In Containers
Container-grown lemon balm needs more frequent watering than garden plants. Check the soil daily in hot weather. Fertilize lightly every month during the growing season with a balanced liquid fertilizer.
Repot every two years or when roots fill the pot. Divide the plant at that time to keep it healthy. Container plants can become root-bound if not maintained.
Benefits Of Transplanting Lemon Balm
Why go through the trouble? Here are the payoffs.
- Healthier plants: Fresh soil and more space reduce disease and stress.
- More plants: Division gives you new starts for free.
- Better control: Move it to a spot where it won’t take over.
- Improved flavor: Stressed or crowded plants produce less aromatic leaves.
- Aesthetic appeal: A well-placed lemon balm plant looks great in any garden.
Transplanting also lets you refresh the soil. Over time, soil can become depleted. Moving the plant to a new spot with rich soil gives it a boost.
When To Avoid Transplanting
There are times when transplanting isn’t a good idea. Avoid it during flowering—the plant is putting energy into blooms, not roots. Also skip transplanting in extreme heat or cold. The shock can be too much.
If your lemon balm is diseased or pest-infested, don’t transplant it. You’ll just spread the problem. Treat the issues first, then move the plant.
Very old, woody plants may not transplant well. They have a tough root system and may not recover. It’s better to take cuttings or divide younger parts.
Frequently Asked Questions
Can I Transplant Lemon Balm In Summer?
Yes, but it’s risky. If you must, do it on a cool, cloudy day. Water deeply before and after. Provide shade for the first week. Expect some wilting, but it should recover with care.
How Deep Should I Plant Lemon Balm?
Plant it at the same depth it was growing before. The crown should be level with the soil surface. Planting too deep can cause rot, too shallow dries out roots.
Does Lemon Balm Need Full Sun?
It prefers full sun but tolerates partial shade. In hot climates, afternoon shade prevents leaf scorch. In cool areas, more sun gives better flavor and growth.
How Often Should I Water Transplanted Lemon Balm?
Water every 2-3 days for the first two weeks. Then reduce to once a week. Adjust based on rainfall and temperature. Keep the soil moist but not waterlogged.
Can I Transplant Lemon Balm From A Store Pot?
Absolutely. Store-bought lemon balm is often root-bound. Gently loosen the roots before planting. Follow the same steps for garden or container planting. It will adapt quickly.
