Supplies You’ll Need

Healthy lemon balm plant
Sharp scissors or garden snips
Small glass or jar
Fresh water
Small pots with drainage holes
High-quality potting mix

Step 1: Choose a Healthy Stem

Select a stem about 4–6 inches long.

Look for stems with:

Several sets of leaves
Flexible green growth
No flower buds

Flowering stems use more energy producing seeds than roots.

Step 2: Make the Cutting

Using clean scissors:

Cut just below a leaf node.
Remove the lower leaves.
Leave several healthy leaves near the top.

Roots will develop from the leaf nodes beneath the water or soil.

Step 3: Root the Cutting in Water

Fill a small glass with fresh water.

Place the cutting into the water so the leaf nodes are submerged while the leaves remain above the waterline.

Set the jar in bright, indirect sunlight.

Avoid placing it in harsh afternoon sun.

Step 4: Change the Water

Replace the water every 2–3 days.

Fresh water helps prevent bacteria and encourages healthy root development.

Roots usually begin appearing within 1–3 weeks.

Step 5: Plant Your Rooted Cutting

When roots are about 1–2 inches long:

Fill a small pot with quality potting mix.
Plant the rooted cutting carefully.
Water thoroughly.
Place the pot in bright light.

Keep the soil evenly moist until the plant becomes established.

Can You Root Lemon Balm Directly in Soil?

Yes!

Many gardeners place fresh cuttings directly into moist potting mix.

To increase humidity:

Cover the pot loosely with a clear plastic bag.
Keep the soil lightly moist.
Remove the cover once new growth appears.

Caring for Your New Lemon Balm Plant

After transplanting:

Provide 4–6 hours of sunlight daily.
Water when the top inch of soil becomes dry.
Harvest regularly to encourage bushy growth.
Pinch back stems to prevent legginess.

Lemon balm grows vigorously and responds well to frequent harvesting.

Common Problems

Cutting Wilts

Possible causes include:

Too much direct sunlight
Water not changed often enough
Stem was damaged during cutting

No Roots Develop

Usually caused by:

Older woody stems

Insufficient light

Yellow Leaves

This can happen from:

Overwatering
Poor drainage
Standing water becoming stale
