When watering the African basil, 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 African basil 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 African basil, 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 African basil, 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 African basil have become brittle and brown. It is crucial that you notice the signs of overwatering as soon as possible when caring for your African basil. 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 African basil 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 African basil 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 African basil 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 African basil 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 African basil can show an admirable ability to withstand drought.

When it comes time to water your African basil, 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 African basil can change depending on growth stages as well. For example, when your African basil 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 African basil 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 African basil 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 African basil more water at this time.

The African basil 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 African basil will contract a disease.

It is most common to grow the African basil 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 African basil 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 African basil 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.

The usual goal for the African basil is to have it grow as big and full as possible. While the plant doesn’t require consistent trimming, it can benefit by removing old flowers and any damaged, dead, or diseased leaves. You can also trim back the leaves if it is starting to get too big for the pot and space you are keeping it.

African basil don’t have a winter dormancy cycle at the suitable temperature. With that said, their growth does slow down as the days get shorter, however the leaves don’t die. What does that mean for pruning? It means there’s no specific season where it’s better to prune. Ideally, you will want to wait until the flower blooms before pruning it, which can take about a month after the appearance of the blossom. With deadheading, you’ll want to do this around late spring or when only a few of the blossoms have faded. You should always prune brown or yellow leaves when you notice them. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

Once you’ve pruned your plant, you should dispose of the stems and leaves either by composting the healthy ones or throwing out the diseased parts. You can also fertilize just before or after pruning, which gives African basil a little vitamin boost that can provide it the nutrients needed to better protect itself from any nearby pathogens or diseases. You don’t need much after care when you’re done pruning. It might benefit from light watering and some liquid plant food to encourage new blooms and growth.

Chances are you’re not getting the African basil from seed, which means you’re already getting a mature plant. Since the plant doesn’t have a true dormancy cycle, there are really only two phases: blooming and non-blooming. While the plant is blooming, you should only remove yellow or dead leaves and cut off any brown tips on the leaves. Avoid doing too much pruning during this time as it can stress the plant. Still, you should remove any diseased or dead leaves to keep your plant presentable. The best time to prune is after the blossoms have already wilted. You can remove both the spent blossoms and any old and yellowed leaves at the same time. If you’re noticing a large amount of yellow leaves, you might be overwatering your plant or not giving it enough nutrients. While yellow or brown leaves don’t always mean there’s an issue, if you notice a large amount of leaves shifting colors, it usually means there’s a problem with the plant.

As an evergreen plant, African basil doesn’t have the same cycles as those found in colder areas. The leaves will remain green throughout the year, which is one of the many reasons it is a popular houseplant. If you want to deadhead, you should do so after the blossoms have already wilted. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

How you prune the African basil will depend on whether you’re performing general care or deadheading. For general care, simply cut off the blossoms that have already died. Make sure to get as close to the base as possible and snip at a 45-degree angle. Repeat this for all stalks with wilting blooms. After that, trim back any outer leaves that are old and yellowing. If you simply want to thin the plant out, start with the outermost leaf and work your way in. Avoid removing more than 30 percent of the leaves at once. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

African basil typically needs at least six to eight hours of direct sunlight every day. If you are growing your plant outdoors, make sure to choose a spot that receives full sunlight throughout the day. If you are growing your African basil indoors, try to place it near a south-facing window or another location that receives plenty of sunlight. While African basil needs full sunlight to grow and thrive, it’s essential to avoid exposing them to direct sunlight during high temperatures, such as over 35°C(95℉) or during hot summer afternoons. If the sunlight is too intense, it can cause the leaves to become scorched or wilted. To avoid this, you can consider using sheer curtains or blinds to filter the sunlight or moving the plant to a shadier spot.

If your African basil doesn't receive enough sunlight, it may struggle to grow and may become weak and leggy. The leaves may also start to turn yellow, indicating that the plant is not getting enough sunlight to produce chlorophyll. In extreme cases, the plant may even die.

While African basil needs full sunlight, it’s crucial to avoid exposing it to too much direct sunlight. If the plant is exposed to intense sunlight for an extended period, it can start to show signs of sunburn, such as brown or scorched leaves. To avoid this, make sure to monitor the plant and move it to a shadier spot if necessary.

For this tropical plant to thrive, you’ll want to keep them between 75℉ and 90℉ (25-32℃). Each species can handle temperatures outside of this range, but keeping it within several degrees of these limits will ensure they grow to their maximum potential. As for its extreme temperature limits, any environment below 50℉ (10℃) or above 95℉ (35℃) will begin to hinder its growth and cause various aberrations to its leaves and stems. This is especially true with low temperatures; even a light frost can cause your tropical plants to perish. Cellular death can begin to happen at a rapid pace, with some species dying in as little as 12 to 24 hours.

While African basil doesn’t require any changes in temperature to enter different growing phases, it is important to stay consistent. Wild temperature fluctuations can slow down its growth regardless of its current phase, so it's always better to keep them in a controlled environment. That optimal temperature range of 75℉ and 90℉ (25-32℃) is vital to maintain, especially staying above the lower limit. Going above 90℉(32℃) isn’t ideal, but as tropical plant it won’t suffer too much. On the other hand, going below 50℉ (10℃) (and especially 40℉/5℃) will begin to directly damage this heat-loving plant species.

African basil does not need different temperatures for different growing seasons. The most important step in seasonal care is to keep the environment within the optimal temperature range. That's why it's always best to keep this plant indoors. That way, you can control the temperature no matter what the climate is like outside. Light is also important for tropical species, with all of these plants preferring a partial side level of sun exposure. This means any light they receive needs to be dappled or filtered, with bright but indirect light being the best option when growing your plants indoors. Too much direct sunlight can negatively affect your plant’s leaves, reducing its growth potential.

Tip #1: Don’t Leave Your Plant Near Windows in Colder Months If you want to make sure your plant isn’t exposed to colder temperatures, you may want to keep them away from windows. In colder months like late fall and winter, even the smallest draft can leak cold air into your home through cracks in your windows. While this air usually dissipates and warms up as it travels throughout your home, any plants placed in close proximity to the window will be affected. Move your tropical plants into an area where they will still get bright but indirect light, while making sure they won’t be affected by potential drafts. Tip #2: If You Find Dry Patches, Your Plant May Be Getting Too Much Sunlight or Heat You may notice the leaves become white or even scorched on a sunny day. These discolorations and unusual markings usually indicate that a plant is getting too much heat or sunlight, and it may be dehydrated. Excess light and heat will dry out the soil, stopping plants from getting the moisture they need to support their cellular structure. It also slows down or stops the process of photosynthesis, further hindering growth. If ignored for too long, these dry spots can spread and eventually result in the death of your plants. Tip #3: Avoid Frost at All Costs Colder temperatures and frost can damage your plants by causing ice crystals or disrupt normal physiological activity. This makes it nearly impossible for water to move freely throughout plant tissue, creating a deficit of moisture in their stems and leaves. You can tell a plant has been damaged by frost if it begins to suffer from hydrosis (it will appear as though it's soaked with water.) If the problem persists, your plants may begin shriveling and turning a dark brown or black hue. After that, the plant will almost certainly die.

The best way to maintain the right temperature range for African basil is by keeping an eye on both the climate and humidity. You’ll want to try to keep each species in a room where you have access to climate control, keeping the heat in the temperature range best mimics its natural habitat. The humidity levels will also have a direct effect on temperature, so it's important to monitor these as well. You can artificially raise the humidity of your growing space by using a humidifier or lightly misting the leaves with water. If you intend to grow this species outside, you may find it difficult to maintain the right balance of temperature and humidity. If temperatures begin to drop or the air becomes too dry, your best option is to find room within your home and move your plant inside. An indoor growing space will allow you to control the climate more closely, helping your plant reach its full potential.

Fertilizer, and soil nutrients in general, are an essential form of fuel that your African basil will use to maintain healthy growth. In general, plants use the nutrients they find in the soil to develop new plant material and keep their existing components in good condition. For the African basil specifically, fertilization is necessary to help this plant display the best version of its flowers. Since the flowers are the main form of attraction to this plant, most gardeners will want to do all they can to ensure the flowers appear in their best form. Fertilization is one of the most reliable ways to help your African basil produce the best possible blooms.

The African basil goes through two main phases throughout each year. The first phase is the dormant phase, in which this plant will put forth minimal new growth. This dormant phase takes place during the winter. The other phase is the active growth phase, which takes place during spring and fall, which is when your African basil will need fertilization the most. Generally, it is best to fertilize your African basil starting in the spring months. You should repeat the feeding about once per month throughout the rest of the spring and through most of the summer. As fall approaches, you can begin to reduce your fertilization rate.

You want to support African basil growth, but you also don’t want to cause root burn. Your plant is actively growing in the spring and summer, it’s when the extra nutrients are necessary. In the fall and winter, your plant will enter its dormancy stage. It’s when you want to stop fertilizing.

The ideal fertilizer for a African basil is one that has a relatively balanced mix of the three main plant nutrients, with slightly higher amounts of phosphorus. Alternatively, some gardeners choose to improve their African basil 's soil by adding organic materials such as compost, worm castings, and manure. Fertilizers can come in many forms, and most of these forms will work well for your African basil. However, some of the best fertilizers for African basil come in either a liquid or a powdered form. Regardless of which you use, you should ensure that you dilute your fertilizer and apply it while watering your African basil.

Once you have found a suitable fertilizer and learned the ideal fertilization schedule for your African basil, you are ready to learn how to apply your fertilizer. When feeding your African basil, the most reliable method is to mix your liquid fertilizer with water before applying it to the soil. Each fertilizer may have different directions on how to feed your plants. Usually, it is best to follow the manufacturer's guidance on how to use the fertilizer they produce. These instructions should include information on how to properly dilute the fertilizer to prevent overfertilization. Mixing your fertilizer in water is an easy process, and once it is complete, all you need to do is pour the mixture into the soil where your African basil lives.

Overfertilization is something that you should consider when caring for any plant, but it is especially important when growing a African basil. A African basil, when overfertilized, will show clear signs of distress, which, at times, may be so serious that they lead to the death of your plant. Overfertilized African basil will likely show leaf discoloration as well, including browning. In the worst-case scenarios, excessive fertilization will draw moisture out of your plant's roots, which can cause it to decline quickly.
