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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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!

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.

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.

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.

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.

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.

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.

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.

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.

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.
