Lemon balm (Melissa officinalis) Flower, Leaf, Care, Uses

The key to knowing when to water lemon balm is to look at its leaves. Water the plant as soon as they begin to look wilted. Timings can vary depending on the plant's location. so checking the leaves is the best indicator. Water deeply so that it reaches the entire root system and make sure the soil has dried somewhat before rewatering.

Fertilization

Lemon balm performs better when fed using a soil mulch rather than a fertilizer. This is because the plant's delightful aroma is reduced by using fertilizers. So instead of fertilizing apply an inch or two of good organic mulch to the soil at the start of the growing season.

What is the best way to water my Lemon balm?

When watering the Lemon balm, you should aim to use filtered water that is at room temperature. Filtered water is better for this plant, as tap water can contain particles that are harmful to its health. The reason that the water should be at room temperature or slightly warmer is that the Lemon balm comes from a warm environment, and cold water can be somewhat of a shock to its system. Also, you should avoid overhead watering for this plant, as it can cause foliage complications. Instead, simply apply your filtered room temperature water to the soil until the soil is entirely soaked. Soaking the soil can be very beneficial for this plant as it moistens the roots and helps them continue to spread through the soil and collect the nutrients they need.

What should I do if I water my Lemon balm too much or too little?

Both overwatering and underwatering will be detrimental to the health of your Lemon balm, but overwatering is a far more common issue. When this species receives too much water, its stems and leaves may begin to wilt and turn from green to yellow. Overwatering over a prolonged period may also lead to diseases such as root rot, mold, and mildew, all of which can kill your plant. Underwatering is far less common for the Lemon balm, as this plant has decent drought tolerance. However, underwatering remains a possibility, and when it occurs, you can expect to find that the leaves of your Lemon balm have become brittle and brown.

It is crucial that you notice the signs of overwatering as soon as possible when caring for your Lemon balm. Some of the diseases that arise from overwatering, such as root rot, may not be correctable if you wait too long. If you see early signs of overwatering, you should reduce your watering schedule immediately. You may also want to assess the quality of soil in which your Lemon balm grows. If you find that the soil drains very poorly, you should replace it immediately with a loose, well-draining potting mix. On the other hand, if you find signs that your Lemon balm is receiving too little water, all you need to do is water more regularly until those signs have subsided.

How often should I water my Lemon balm?

If your plant is in a pot. The most precise way to decide whether your Lemon balm needs water is to plunge your finger into the soil. If you notice that the first two to three inches of soil have become dry, it is time to add some water.

If you grow your Lemon balm outdoors in the ground, you can use a similar method to test the soil. Again, when you find that the first few inches of soil have dried out, it is time to add water. During the spring and early fall, this method will often lead you to water this plant about once every week. When extremely hot weather arrives, you may need to increase your watering frequency to about twice or more per week. With that said, mature, well-established the Lemon balm can show an admirable ability to withstand drought.

How much water does my Lemon balm need?

When it comes time to water your Lemon balm, you should not be shy about how much water you give. With the first two to three inches of soil dry, this plant will appreciate a long and thorough watering. Supply enough water to soak the soil entirely. The amount of water you add should be enough to cause excess water to flow through the drainage holes at the bottom of your pot. If you don’t see excess water draining from the pot, you have likely underwatered your plant. But do not let the water accumulate inside the soil, which will be very dangerous to the plant as well. Alternatively, a lack of water draining through the pot could indicate poorly draining soils, which is detrimental to the health of this plant and should be avoided. If the plant is outside, 1 inch of rain per week will be sufficient.

How should I water my Lemon balm at different growth stages?

The water needs of the Lemon balm can change depending on growth stages as well. For example, when your Lemon balm is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your Lemon balm will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your Lemon balm will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your Lemon balm more water at this time.

How should I water my Lemon balm through the seasons?

The Lemon balm will have its highest water needs during the hottest months of the year. During the height of summer, you may need to give this plant water more than once per week, depending on how fast the soil dries out. The opposite is true during the winter. In winter, your plant will enter a dormant phase, in which it will need far less water than usual. In fact, you may not need to water this plant at all during the winter months. However, if you do water during winter, you should not do so more than about once per month. Watering too much at this time will make it more likely that your Lemon balm will contract a disease.

What's the difference between watering my Lemon balm indoors and outdoors?

It is most common to grow the Lemon balm indoors for any gardener that does not live in temperate and tropical regions. Those gardeners should consider the fact that soil in a container can dry out a bit faster than ground soil. Also, the presence of drying elements such as air conditioning units can cause your Lemon balm to need water on a more frequent basis as well. if you planted it outside. When that is the case, it’s likely you won’t need to water your Lemon balm very much at all. If you receive rainfall on a regular basis, that may be enough to keep your plant alive. Alternatively, those who grow this plant inside will need to water it more often, as allowing rainwater to soak the soil will not be an option.

When should I prune my Lemon balm?

You can prune your Lemon balm any time you notice dead, diseased, or damaged leaves during the growing season. Once you notice such a leave, locate an unwanted leaf, then follow its stem all the way to the bottom of petiole. Removing dead stems will increase the light and ventilation of the plant and help it to grow. You can cut its stem just above the soil’s surface to remove it. Such pruning can take place as needed during spring and summer. Also, this plant can bloom any time between spring and fall, and some gardeners choose to remove flower buds before they have a chance to open. Removing unopened flower buds allows this plant to focus most of its growing energy on its beautiful leaves. However, pruning in this manner does not necessarily influence the plant’s overall health. Cutting back should be done late in the winter to early spring. Ideally, you should wait until you see new basal growth before you cut off the dead and dried winter parts, to about 6 inches from the ground.

How can I prune my Lemon balm?

Pruning the Lemon balm is as easy as waiting until you notice dead or damaged leaves on your plant. When you recognize these leaves, equip yourself with a pair of sharp and sterile hand pruning shears. Hand pruning shears will work best as larger tools like loppers will not be well suited to the precise cuts you need to make. Once you have a proper set of pruning tools, locate an unwanted leaf, then follow its stem all the way to the bottom of petiole. Removing dead stems will increase the light and ventilation of the plant and help it to grow. Cut the stem just above where it exits the soil to remove it entirely. If you wish to stop this plant from flowering, you can use the same pruning shears to remove any buds before they open. Finally, you may prefer to just trim off dead or damaged portions of the plant, including deadheading spent flowers, to keep it looking its best. This can be done at any time of year. Diseased or damaged stems should be cut right at the soil line and removed completely. Blooms should be cut off just below the flower head. Cutting back should be done late in the winter to early spring. Ideally, you should wait until you see new basal growth before you cut off the dead and dried winter parts to about 6 inches from the ground.

What should I do after pruning my Lemon balm?

All that is required of you once you have pruned your Lemon balm is to clean up. Once you have pruned, deadheaded, or cut back your Lemon balm, gather the bits you have cut off and discard them. If there are any diseased parts of the plant that you have pruned away, do not discard them with the rest of the pruned pieces. Diseased foliage should be disposed of. When watering after pruning, be careful not to touch the wound to prevent fungus from infecting the plant through the fresh wound. Placing Lemon balm in a well-ventilated location will also help the wound to dry out and heal in time.

Are there any tips for pruning my Lemon balm?

For your major pruning, use sharp pruning sheers that will make clean cuts to avoid damaging your plants. As you are pruning your Lemon balm, step back occasionally to check the appearance of the plant to make sure it has the shape you want and that you are pruning it symmetricaly. It is recommended that gloves and safety glasses be worn while pruning Lemon balm.

Are there any instructions for pruning my Lemon balm?

Pruning is an important part of plant care and maintenance. Different plants have different pruning requirements. Some plants may need little to no pruning, while others may require more specific attention. Most plants should be pruned to remove damaged or unhealthy foliage. Other plants may be pruned to control their shape and size. Pruning may even be done to remove the flower heads of plants and stop them from self-seeding. Although some gardeners may find pruning a tedious task, it is a necessary evil and is an essential part of keeping your plants happy and healthy.

What type of sunlight does Lemon balm need?

Lemon balm needs full sun every day, and these plants rely on a minimum of six hours of sunlight to keep their leaves, roots, and blooms in a healthy state. Even though most perennials need six hours of sunlight a day, plants like the Orange Daylily or Giant Coreopsis could live off less sun for a minimum of three hours daily. Even though these perennial flowering plants can live with only three hours of direct sunlight, they won't be able to thrive like they would in sunnier conditions.

Can sunlight damage Lemon balm? How to protect Lemon balm from the sun and heat damage?

The few Perennial Flowering Plants that don't like excessive heat in warm climates might react poorly to too much sun if they have heat damage. These plants may wilt or dry out from too much sun and may also develop growth issues if they're regularly in the sun during the most intense heat of the day. Some plants don't need protection from the light afternoon sun, but those that are harmed by intense afternoon exposure should be provided some shade in warmer climates. Gardeners could give these plants plenty of shade by planting them in spots that don't receive direct heat during the afternoon, like under trees or behind bushes.

Should I protect Lemon balm from sun exposure?

While many perennial plants need plenty of sun to bloom to their fullest extent, some of them benefit from less sun in warmer climates. For example, people who live in hotter climates might want to provide shade for their flowering perennials in the hot afternoon sun, and this is even more true for months in the summer.

Even though some perennial flowering plants will benefit from partially shaded in the hottest climates, plants like the Giant Coreopsis aren't intimidated by too much sun. They might sit outside in the full sun in hot weather and still thrive.

What will happen if Lemon balm gets inadequate sunlight?

If you're growing Lemon balm and you aren't getting enough sunlight, you'll notice signs of inadequate requirements in your plants. Most plants won't produce as many blooms as they would if they had full sun exposure. Some plants will develop dry spots on their leaves, but most of these plants will still bloom in the inadequate sun. Even though they bloom, the flowers will be smaller and less full.

Does Lemon balm need special care about sunlight during its different growth stages?

Lemon balm is great flowers in gardens and will have optimum blooming if it gets six hours of sunlight a day minimum. Sometimes, flowers stay fresh longer if they're partially shaded during the really hot parts of the day. When Lemon balm is young, gardeners want to ensure their younger plants are getting plenty of sunlight but don't have to endure intense heat during the afternoon sunlight. If you have a fully mature plant, provide it with plenty of sun so it may keep up its growth properly.

How much light does Lemon balm need for photosynthesis?

Lemon balm will need a minimum of six hours of light to best support their photosynthesis cycles. These flowering plants need the sun to help their foliage and blooms grow. However, certain perennial flowering plants like the Giant Coreopsis might need anywhere from eight to twelve hours of full sun a day to maintain their large flowers and healthy foliage.

How much light should Lemon balm get per day to grow healthily?

If you want your Lemon balm to grow healthy and bloom as much as possible during its blooming season, you should try to give your plant six hours of direct sunlight. Some perennial plants might even do more sunlight and could sit in the sun for up to twelve hours, depending on the heat in the area and the general environment. Plants like the Red Hot Poker and Giant Coreopsis thrive in much hotter climates and might sit in all types of strong sunlight.

Some home gardeners have to use grow lights because their spaces don't allow for tons of outdoor sunlight. Most perennials could grow happily in grow lights, but they will need anywhere from eight to fourteen hours of artificial light to stay strong since these lights don't have as much power as the sun.

What is the optimal temperature for Lemon balm?

The best temperature for Lemon balm depends on the time of year. There are two primary seasons to discuss for temperature: the growing season, and the dormancy season. During the growing season, once Lemon balm has begun to sprout, the ideal temperature range should be anywhere from 65~80℉(18~27℃). Any colder than 15℉(-10℃), and the plant will suffer; its leaves may brown and wilt, but if this is a short cold snap, then Lemon balm may be able to survive with some help.

During the warmer parts of the year, Lemon balm will need to be similarly protected from temperatures that are too high. 95-105℉ (35-40℃) is the top of this plant’s temperature range, and anything above that will compromise the integrity of the foliage and blooms of Lemon balm. Hotter temperatures can cause wilting, drooping, and even sunburn on the leaves, which can be difficult for Lemon balm to recover from. There are quite a few ways to combat this issue that are quick and easy!

Temperature requirements for first year or seedling Lemon balm

If this is the first year of your Lemon balm outside as a new plant, then it may need a little extra tending during the coldest months of the year. Not only can frost more severely damage a first-year Lemon balm, but it can also prevent it from growing back as a healthy plant come spring. This plant needs to be kept at 40℉(5℃) or above when they’re not yet established, which can be done either by bringing your Lemon balm inside for a month or two, or putting up mulch or fabric barriers that protect from frost damage.

It’s also a good idea to plant Lemon balm in a shadier spot during the first year or two, as smaller and weaker plants have a more difficult time maintaining their own temperatures in the heat. First-year Lemon balm should receive no more than five hours of direct sunlight per day, particularly if the ambient daytime temperature gets above 80℉(27℃). Shadecloth and frequent watering or misting are the keys to summer heat control.

How can I protect Lemon balm from extreme temperatures?

If cold temperatures (below 15℉(-10℃)) do occur during the growing season, there are a few measures you can take to help protect Lemon balm from frost or cold damage. If you’re growing Lemon balm in a container, then the container can simply be brought inside in bright, indirect light until the temperatures rise up over the lower threshold again. Another option that’s better suited for ground-planted Lemon balm is to use mulch or horticultural fabric to create an insulated barrier around the plant, which will protect the plant from frost and cold wind.

For temperatures that are hotter than 80℉(27℃) in the shade during the day, be careful to only expose Lemon balm to six hours or less of sunlight per day, preferably in the morning hours. Putting up shade cloth, or a fine plastic mesh, can help reduce the amount of direct sunlight that hits the plant during the hottest parts of the day. You can also install a misting system that allows for a slow release of cooling mist around the base of the plant during the day to lower ground temperatures.

Dormant season temperature recommendations for Lemon balm

During the cold winter months, Lemon balm needs a certain measure of cold in order to stay in dormancy until it’s time to sprout. Sprouting too early, that is before the danger of the last frost has passed, can be fatal to Lemon balm, especially if it’s already had a head start when the frost hits. Winter temperatures should ideally stay below 32℉(0℃), but if they get up to 40℉(5℃), everything will be just fine.

An unexpected warm spell during the cold months, which can happen in more temperate climates like woodland rainforests, can trigger a premature sprout from Lemon balm. In this case, if there’s still imminent danger of frost, you may want to try covering it with clear plastic on stakes so that the cold has less of a chance of damaging the new sprout. This setup can be removed when the danger of frost has passed. Occasionally, Lemon balm will be able to resprout at the correct time without any help, but this method increases the chances of a successful second sprouting.

Why do I need to fertilize my Lemon balm?

The leaves of the Lemon balm comprise most of its main structure, and fertilization is one of the most impactful ways that you can ensure that those leaves look great while also serving their function. Proper fertilization will help your Lemon balm hold leaves with consistent color and a healthy texture.

Fertilization also works below the soil's surface to help your Lemon balm generate new roots and maintain the roots that are already part of the root system. This means that fertilization will not just keep your plant healthy now, but it will also help your plant be better capable of absorbing soil nutrients in the future.

When is the best time to fertilize my Lemon balm?

If you grow your Lemon balm outdoors each year, this perennial plant will send new growth shooting out in early spring. The emergence of those leaves is a sign that the time is right to begin fertilization for the year.

Often, a Lemon balm will perform just fine with a single application of fertilizer when the spring arrives. However, if you wish to maximize the growth of your Lemon balm, you can repeat the feeding multiple times throughout the spring and early summer. If you choose this route, you can feed your Lemon balm about once every month to a month and a half.

When should I avoid fertilizing my Lemon balm?

In the late fall and winter, your Lemon balm will enter a dormant phase in which it will no longer produce new growth. At this time, you should avoid fertilizing your Lemon balm. If you choose to fertilize multiple times during spring and summer, you should begin reducing your fertilization rate as summer approaches, as your Lemon balm 's growth rate will also slow.

Overall, it is never a wise choice to fertilize your Lemon balm during times when the weather is unseasonably hot or when the soil is extraordinarily dry. Fertilizing in either of those cases can stress your Lemon balm and cause it to perish prematurely.

What type of fertilizer does my Lemon balm need?

Fortunately, choosing the best fertilizer for a Lemon balm is a very straightforward task. These plants will thrive on a general-purpose garden fertilizer that has equal amounts of nitrogen, phosphorus, and potassium. A fertilizer that has a ratio of 10-10-10 or something similar will be very effective. When in doubt, be sure to avoid fertilizers that have high amounts of nitrogen.

Most of the best fertilizer for a Lemon balm will come in a granular form. These fertilizers should be slow-release and will be very easy to apply to the soil. It can also be helpful to feed your Lemon balm using an organic soil amendment such as compost.

How do I fertilize my Lemon balm?

Wait until your Lemon balm has just barely poked its first leaves through the soil's surface in early spring. Once you see that sign, apply a granular slow-release fertilizer with a balanced formula to the soil that surrounds the base of your Lemon balm.

You can repeat a similar process later in the season if you choose. When reapplying fertilizer to a Lemon balm, you should, again, apply the fertilizer to the soil at the base of the plant rather than to the plant itself. At times, this may require you to move some leaves out of the way to access the soil above the roots. It's also often a good choice to water your Lemon balm before and after you feed it.

What happens if I fertilize my Lemon balm too much?

The Lemon balm doesn't necessarily need to receive high volumes of fertilizer each year, which means overfertilization is entirely possible. If you overfertilize your Lemon balm, you will likely notice first that the leaves have turned brown.

Overfertilization of Lemon balm is especially common if you use a fertilizer that has higher concentrations of nitrogen. High nitrogen content will likely cause the leaves of your Lemon balm to become discolored, lose much of their moisture, and begin curling at the margins. Many gardeners avoid such complications by limiting fertilization of their Lemon balm to once per year in early spring.

Feng shui direction

East

Lemon balm harmonizes well with East-facing spaces, as it symbolizes growth, renewal and tranquility. This direction is associated with the Wood element, which lemon balm is said to enhance with its lush foliage, promoting balance and positive energy flow throughout the environment.

Water

Every week

Lemon balm hails from regions in the Mediterranean, Western Asia, and South Europe where weather conditions involve humidity and natural soil moisture due to consistent, moderate rainfall. Such constant hydration without waterlogging frames lemon balm's watering preferences. Emulating this requires regular, light watering, enough to keep the soil moist but not drowned, signifying an innate tolerance for relatively higher moisture levels compared to dry-climate plants.

Lighting

Full sun

Lemon balm thrives when exposed to abundant sunlight throughout the day, though it can also get by in slightly shadowed spots. Its origins in open meadows contribute to its sun-loving disposition. Overexposure may result in leaf scorching, while insufficient exposure could hinder its robust growth and vitality.

Temperature

0 38 ℃

Lemon balm originates from regions where the temperatures are typically 68 to 95 °F (20 to 35 ℃). This indicates a distinct preference for a warmer climate. For optimum growth, adjust temperatures to meet these preferences whenever possible.

Transplant

1-2 feet

Lemon balm ideally flourishes when transplanted during mid-spring to early summer, as this period offers optimal growing conditions. Choose a sunny or partially shaded location with well-draining soil. If necessary, enrich the soil with organic matter prior to transplanting for better growth.

Common Pests & Diseases

Common issues for Lemon balm based on 10 million real cases

Leaf beetles

Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.

Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Brown spot

This infection can cause brown spots or patches to appear on the plant.

Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Sap-sucking insects

Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.

Solutions: Sap-sucking insects can be hard to spot, as they are often small and attach to the undersides of plant leaves. If you see signs of an infestation, follow these steps to eradicate it. Hand-pick bugs and remove eggs: Inspect your plants for insects and drop any you find in a container of soapy water. Look carefully at the undersides of plant leaves and squish any egg clusters you find. Use Insecticide: Targeted spraying can take out sap-sucking insects. Small infestations can be controlled with insecticidal soap, though larger outbreaks might require a stronger spray. Introduce natural predators: Many insects, including ladybugs and praying mantises, love to feast on sap-suckers. You can purchase them at garden stores and release them near infected plants, or encourage wild ones by creating habitat space.

Thrips

Thrips are 1 to 2 mm bugs with slender black or translucent-yellow bodies. They move quickly and feed on the plant's sap.

Solutions: Thrips can be controlled in several ways. Spray plants with Pyrethrin, which is an organic pesticide derived from marigolds (follow label instructions) or Permethrin, the synthetic version of Pyrethrin. Introduce beneficial insects to the garden that eat thrips, such as minute pirate bugs and green lacewings. Remove heavily infested plants from the area and discard. Address viral diseases that may have been transmitted by the pests. For less serious cases -use a hose to spray the thrips off of the plants.

Underwatering

A lack of water will cause the leaves to gradually turn yellow starting at the base of the branch while the entire plant appears to wilt.

Solutions: Your plant is very thirsty and needs water promptly. You can revive your plant by giving it water. The easiest technique is to slowly pour water into your plant’s soil so that the whole surface is moistened. If you pour the water too quickly, the water will flow directly through rather than diffusing throughout the soil. If your plant’s pot does not have drainage holes, do not give your plant more than about a third of the pot’s volume of water. If your plant’s pot does have drainage holes, you can add water slowly until the soil is thoroughly moistened and the water flows freely through the pot. If you trim off yellow leaves to improve the plant’s appearance, do not remove more than a third of the plant’s leaves. It may be better to wait until leaves have died and fallen off to remove them.

Aged yellow and dry

Natural aging can cause leaves to turn yellow and dry out.

Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
