Growing Lemon Verbena and Keeping it Alive
Growing Lemon Verbena and Keeping it Alive.Growing Lemon Verbena.North American home gardeners who try to grow this tender, wonderfully fragrant perennial herb may succeed more often than they fail, but a large number who try year after year eventually develop a deep sense of frustration and guilt when they repeatedly “commit herbicide”.A Spanish researcher assigned it to the genus Aloysia (named for Maria Louisa, wife of King Charles IV of Spain) because its fruit separates into two nutlets, whereas the fruits of Verbena species separate into four.Though lemon verbena is sometimes still offered as L. citriodora, it has long been reassigned to the genus Aloysia, this time as A. triphylla.The plant will need little to no water while it is dormant, whether indoors or out.Fertilize lemon verbena as you would any other herb plant: as often as every two weeks indoors or every four weeks in the garden when the plant is growing vigorously, less during periods of slower growth, and not at all during dormancy.Although lemon verbena often loses its leaves and becomes dormant when days become short, it grows year round in its native haunts, where day length is virtually unchanging, and dormancy does not seem to be a requirement for its health and longevity.It can be triggered by bringing a potted plant indoors in late summer or after the first frost, by digging up a plant from its summer garden spot and potting it for indoor winter growing, by transplanting a small plant into a larger pot, or simply in response to a strong, cold draft.Many gardeners grow lemon verbena in a pot so that it will be easy to move indoors and out as the weather dictates.Choose a pot at least 12 inches in diameter to allow the roots ample growing room and to limit the effect of short-term air-temperature changes on soil temperature.It may be helpful to cut such plants back a little to accommodate the loss of roots.Different sources list different temperatures—from 14 degrees to 22 degrees Fahrenheit—below which lemon verbena is not likely to survive.One experienced gardener recommends that you resist the temptation to perform such a test because the dead wood protects that which is alive; if your curiosity can survive the wait, the answer will come eventually in the form of new growth (or its continued absence).Like other plants, lemon verbena transpires or gives off water mostly through its leaves, and it stands to reason that a leafless plant uses far less water than one covered with leaves.One of the common ways gardeners kill lemon verbena is by overwatering during leafless periods; this is especially easy to do if you’ve been watering on a time schedule.In early spring, the plant is watered, occasionally fertilized, and placed in a warm, sunny spot; growth should begin within a couple of weeks.Those who grow this plant successfully advise taking basal cuttings of the current year’s growth in summer when the plant is growing vigorously.Such cuttings root fairly easily (see “Growing Herbs from Stem Cuttings” in the February/March 1993 Herb Companion).Lemon Verbena Pests.Why We Keep Trying to Grow Lemon Verbena.Lemon Verbena Sources.HC, 20150-A Rough & Ready Trail, Sonora, CA 95370.HC, 141 North Street, Danielson, CT 06239.Our summer temperatures range into the 90s and sometimes to 100 degrees.Hope springs eternal; I’m keeping the pot and eyeing another lemon verbena plant.I always think, “It just has to live this time.And Tales of Herb Growing Success.Last spring, I brought home a lemon verbena and planted it directly into the garden.The second day, I cut the pathetic stem to about 12 inches.Since they must be moved in for winter, I keep them all in pots with standard potting soil, and I keep the pot significantly larger than the plant so it’s not rootbound in winter when it’s cold.(I’ve tried leaving the leaves on, but they fall off with the cold anyway.).I water only when bone dry.My plants begin to leaf out in February when it’s still too cold to move them outside.I’ve experimented with moving some plants outside when light frosts (around 30 degrees) are still expected, and keeping some inside until it’s warmer out.I’ve changed my annual routine: I wait until the last possible minute to dig it up, which is about the beginning of November (unless it snows).At least once a week, I give it about 1 1/2 quarts of water, and I mist the leaves frequently.One year it lost all its leaves, but they came back.Last year, it kept its leaves most of the winter.I cut back all stems immediately to 6 to 8 inches from the soil, and then neglect them until February, watering them only lightly once a month or less.It takes about three weeks for some green to poke through, at first at the ends of the branches.Bring it indoors in fall and isolate it from other plants that attract whiteflies.As with most other plants, there are probably as many ways to grow lemon verbena as there are growers.
What Is the Best Mix of Herbs to Grow Together in a Pot?
Herbs grown together in a pot can work if you harvest their leaves regularly for cooking, which keeps the plants small and prevents any one plant from taking over the space and squeezing out the other plants.Pots prevent them from spreading out, and the original plants don't live very long.Don't mix different mints in the same box because they interbreed and will produce some new and probably not as deliciously fragrant varieties.Lemon-Scented Plants. .
