What it is
Lemon Balm (Melissa officinalis) is in the Lamiaceae (Mint) family. A calming lemon-scented mint relative for tea. Like mint, it spreads — give it room or a pot.
How to grow it
It wants part sun, water it moderate, and give it average, moist soil. Target a soil pH around 6.0–7.5. Space plants about 18 in apart. Expect roughly 70. Hardy perennial.
How it's used
Lemon Balm is used: tea, fresh, infused.
🔎 How to identify it
- Opposite crinkled leaves
- Square stems
- Strong lemon scent

How to grow & propagate lemon balm
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate lemon balm
Almost everything in the mint family roots from cuttings so readily it feels like cheating. Snip a 4–5 inch non-flowering tip, strip the bottom leaves, and either set it in a glass of water on the windowsill or push it straight into damp potting mix. You'll usually see roots in 1–2 weeks. Seed works too, but cuttings give you an exact copy of the parent — which matters when one plant tastes better than its neighbor.
Beginner's path: take more cuttings than you think you need. They're free, they cost you nothing but a few minutes, and the ones that take more than make up for the ones that don't. This is how a single plant becomes a hedge, a row, or a gift for every neighbor on the street.
Growing lemon balm in Texas
Give it part sun and average, moist soil. Match the spot to the plant and most of the battle is already won.
Because it's a perennial, the work is mostly up front. Get it sited and established and it comes back on its own year after year — one of the best returns on effort in the whole garden.
In a container it'll dry faster than in the ground, so check the top inch of soil daily in summer; pots on a hot Texas patio can need water every single day.
Harvesting
Figure on roughly 70 before you're harvesting. Pick herbs in the morning after the dew dries for the strongest oils, and harvest little and often — regular cutting keeps a herb bushy and stops it bolting. The part you're after: leaves.
Making more for free
Save it the easy way — vegetatively. Because you can clone this plant from a cutting, division, or piece of root, you never have to buy it again: keep one healthy mother plant and make all the copies you want.
Keep this knowledge offline
A garden full of lemon balm is a real asset when times get hard — but the know-how to grow, store, and use it shouldn't live only on a website you can't reach. That's why I keep a copy of the references I rely on on a local server at home. Project NOMAD is a free, open-source way to run Wikipedia, survival and medical guides, maps, and even a private AI on your own hardware — knowledge that keeps working with no internet, no cloud, no signal.
