How to Grow Lemon Balm (Melissa Officinalis)

How to Grow Lemon Balm
Lemon balm is one of those plants that make herb keeping worthwhile. If you've ever entertained the notion of a cottage garden complete with cabbage roses, hollyhocks and even a sedate stand of English ivy, there's no doubt lemon balm would have a place somewhere in that idyllic landscape.

How to Grow Lemon Balm

Lemon balm is a member of the mint family, and like all the mints, it tends to ramble. It produces long stems that start out tidy but eventually begin to lean every which way like a head of unruly hair. Wandering by a patch in spring you'll see light green, toothed leaves in a dome shaped mound. The plant can grow to almost five feet in some cases, but tends to be somewhat smaller -- and certainly looks best if cut back regularly to maintain a cohesive shape.

Originally a native of southern Europe, lemon balm now grows wild in many parts of the world, including areas of the U.S. It's a perennial in hardiness zones 5 through 9. It's also a bee magnet. The "melissa" in its scientific name is Greek for honeybee. You've probably heard that honey bees have been having a tough time with parasitic wasps and pesticides in recent years. Show your bee love by filling a corner of your garden with lemon balm. Imagine the honey that pairing would produce.  Oh, and if you've had trouble pollinating your squash blossoms (or anything else), plant a little lemon balm nearby for added insurance.

This versatile herb is easy to grow. For everything you get into the bargain, you'd expect lemon balm to be persnickety about soil pH or susceptible to wilt or vulnerable to the predations of common insects. It turn out that everything about this little plant is good news, though.

The literature typically suggests planting it in soil with a neutral pH (7) and warns of potential problems with mildew.  I've found lemon balm is adaptable and more rugged than most writers give it credit for. Just give it decent soil and protect it from punishing heat with a layer of mulch and a regular watering schedule -- or at least place it in a location that receives afternoon shade. It will tolerate somewhat boggy soil, too.

Where many mints tend to take over a garden plot, lemon balm is less aggressive about usurping real estate. I've had a few plants in an eastern facing shady spot for the last decade. I prune them to near ground level in fall, and they regrow every spring, much like peppermint and other common mints. They overwinter under inches of compacted snow, and all they ask for is a little fertilizer and some drought protection in spring and summer.

This useful plant also tends to be naturally pest and disease resistant. Many strongly scented herbs are. Rub fresh lemon balm leaves on your skin when you're doing yard chores. It'll act as a homemade mosquito repellent.

If you plan to harvest lemon balm on a regular schedule, it's a good idea to fertilize plants every couple of months for the best results. Here's a good rule of thumb: the more you harvest, the more you should nourish.

Uses for Lemon Balm

Lemon balm is a culinary, cosmetic, medicinal and aromatic herb -- a true herbal bonanza. It has some impressive and handy uses: It's considered one of the top five medicinal herbs for sleep problems, and has been used as a sedative and antianxiety herb for centuries. Along with valerian, it's often referred to as "herbal valium." Where valerian smells like sweaty feet when used in, say, a calming tea, lemon balm smells like lemon blossoms in a cup. It really does have a heavenly aroma.

I've mentioned before that it smells like lemon furniture polish, but the fragrance is more delicate and sweeter than that. Although it's a plant in the mint family, it doesn't smell the least bit minty. If you keep it near a walk or garden gate, it will release fragrance when visitors brush past it. Here's a tip: Try keeping lemon balm with lavender by your entry or porch. It's a nice way to welcome guests and one they'll remember.

Fresh lemon balm leaves are also a nice addition to fruit salad, tossed green salad or fresh salsa. Sprigs make a great garnish that's a nice change from plain old parsley (or dill or cilantro). Chopped or dried leaves also make a mild lemony seasoning for fish, shellfish or fowl. I've even added chopped leaves to cupcake recipes.

Lemon balm is often used fresh or dried as a relaxing tea, and you can add it to homemade potpourri for a clean, light scent that compliments most citrus based blends.

Medicinal Lemon Balm

There's a lot literature available explaining the potential medicinal uses for this herb.  Although its sedative properties are well documented, research into the advisability of using it for more serious disorders is ongoing, though.  It contains over 100 chemical compounds, many of which need additional formal research.

Melissa Officinalis may or may not be effective in treating the following conditions with which it's been associated.  The jury is still out and may be out for some time to come. Your best recourse is to track study results and other news on your areas of interest and discuss those findings with your doctor or herbalist.

  • Alzheimer's disease
  • Herpes
    Lemon Balm Profile
  • Migraines
  • Colic
  • Flatulence
  • Stomachache
  • Toothache
  • Graves' disease
  • Cramps (female discomfort)
  • ADHD (Attention Deficit-Hyperactivity Disorder)
  • Loss of appetite

Lemon balm is an antiviral, an astringent and an antispasmodic.  It is also high in antioxidants (flavonoids).

If you like the idea of taking lemon balm as a calming or sleep inducing herbal remedy but don't like tea, the fresh leaves can be added to bath water for a homemade aromatherapy session. Oral supplements, scented candles and essential oils are available, too. (Inhaling the fragrance can carry many of the same benefits as drinking the tea or taking a lemon balm supplement.)

There are potential side effects when using lemon balm regularly or in large doses.  It may increase the effects of prescription sedative medications. It may make it more difficult for the body to absorb some types of thyroid medications, too.  Lemon balm should be avoided by pregnant or nursing women as its effects on young children and the unborn aren't fully understood.  Consult your doctor or herbalist before taking lemon balm or any other medicinal herb or herbal blend.

Although the use of the common name "lemon balm" is pretty widespread throughout the U.S., you'll also find Melissa Officinalis sold or referred to by other names, like:

  • Bee balm
  • Melissa
  • Sweet Mary
  • Balm
  • English balm
  • Garden balm
  • Honey plant
  • Dropsy plant
  • Heart's delight (Don't you love that?)
  • Cure-all

Growing Lemon Balm Indoors

Lemon balm can thrive indoors as a houseplant, but it needs at least six hours of good light a day.  Here's a quick light test:

On a sunny day, place a sheet of white paper in front of the window where you plan on keeping the pot.  When the sun's shining, position your hand between the window and the paper at about the elevation at which the actual plant will be located.  Your hand should produce a well delineated shadow from which you can see the clear outline of all your fingers.  That's the level of light the plant will need for about six hours a day.  Less light will require the addition of a grow light or the plant will likely have problems.

Offer lemon balm good potting soil and a layer of mulch. Avoid letting the soil dry out completely.

Lemon balm also makes a good commuter plant: a potted patio or deck plant that overwinters indoors.

Special Notes: I've never had powdery mildew problems with lemon balm, but on general principal I do prefer watering all my plants in the morning rather than in the evening.

  1. Oh great post, think I'll have to reconsider planting lemon balm now. I was going to but then thought ' what can I use it for' but your post gave me much more info on it that I could find in my books. Thank you.

  2. What a super informative post! Lemon balm can be a little aggressive in zone 7 (although, like you say, not nearly as aggressive as most mints). Here it tends to spread more by seeds than stolons. Cutting back when in flower has completely controlled any aggressive tendencies in my garden. This is a super fun plant to use in children's garden's. It can take a little manhandling, and kids love the fragrance. One group of kids had a little confusion as to the plant's real name. When digging and dividing, they would toss plants to each other yelling "Lemon BOMB!!!"

    1. Amanda,

      Lemon bomb! I couldn't put it better myself. Thanks for writing.

    where can i find and to purchase this beneficial plant for myself and our senior mother? i currently live in san leandro,calif.

    1. Hi Brian,

      You can find lemon balm from most herb outlets either in San Leandro, Oakland, Hayward, Castro Valley or online. My list of seed catalogs for 2013 contains many online sources for lemon balm. It is also available has an herbal supplement, essential oil and tea ingredient.

  4. This is lovely!! I just got loads of little bushes from a colleague and have only used them in herb baths yet. For one who has trouble sleeping and loves tea in general, this shall be tried!

  5. I GROW THIS IN NEW ENGLAND, A Lovely plant, hides under the snow all winter and springs up in the spring - great mosquito repellant - have it near my deck - so far no bugs!

  6. Okay, I have grown herbs for a very long time, and have grown lemon balm indoors and out. I am not a newbie at gardening, but....
    I do have one question though, I've had my lemon balm out in the back yard in the same place for about 4 years now, propagated it and moved it around, but this year as I was trying to dig some up to move it I noticed that it didn't have my favorite lemon scent anymore! I know my plants, and I have no clue as to why it doesn't smell anymore!??? Any ideas??? I didn't put compost around it last year (I had just given birth to my son last June, so I didn't have time to garden much, although I was out pulling weeds at 8 1/2 months pregnant)
    But has this happened to anyone else before? I am at a total loss! And no, I do not have it confused with another plant.

    1. Hi Trixiestreasures,

      I haven't had problems with lemon balm losing scent, although I do know that mint family plants (catnip, lemon balm, etc.) can cross pollinate.

      Maybe a kindly reader will have some thoughts.

  7. I wondered about that, I do have peppermint that went rogue and is butting up against the lemon balm...

    can i/how do i store it for use before snails and hot sun take the best from the many plants! i have around my garden ..can it be be kept in freezer, i have put bay leaves in freezer and pop them into my cooking when needed, any ideas : )

    1. You can dry lemon balm to use in recipes and for a relaxing tea. (One of the easiest ways is to dry it in the back seat of a hot car. It also freezes well, either in freezer bags or in a water mixture frozen into ice cube trays.

  9. Thanks...great article
