Careful observation of the plant will tell you if you have watering issues. If you overwater your plant you’ll notice: a. The leaves of the plant can appear yellow and are prone to yellow-brown patches at the tips of the leaves. b. If the situation is serious, severe drooping and curling of the leaves may be observed. This is due to the fact that overwatering can cause root rot and the plant is already having a hard time absorbing more water. If your Polka dot begonia is planted indoor, overwatering is all too easy to do with the plant as it cannot tolerate any standing water. The earlier you notice the overwatering the better. If you see standing water or some leaf change, stop watering! Allow the soil to air out over the course of 3-5 days. If you’re noticing signs of root rot, you’ll need to act fast. You’ll have to remove the plant from the pot or ground and then wash off the roots. Remove any dead or decaying roots while trying to keep as much intact as possible. Throw out all the old soil and clean out the pot then add in new soil. If you’re planting in your garden, remove the old soil and replant it in a new location. While overwatering is an issue, so is underwatering. The Polka dot begonia is very sensitive to drought conditions and will quickly decline if they don’t receive consistent watering. Signs of underwatering include: -Curled, pendulous, lifeless leaves; -Some leaves will gradually turn yellow from the bottom; -The edges of the leaves will turn brown. Underwatering tends to be easier to fix than overwatering. Simply increase how often you water the plant. If your plant is drying out quickly, the air might be too dry. Consider increasing the humidity so the soil stays moist for longer. You might also think about moving the plant to a different location if you notice it is getting too much sunlight or the spot is too hot in order to prevent extra evaporation.

Generally speaking, you should water the plant around once per week during spring. However, compared to spring you should increase the watering frequency during the summer but decrease that in winter. However, the timing might change based on a variety of factors such as humidity, temperature, soil type, and so on. To further determine the appropriate watering frequency for your Polka dot begonia, you should use your finger or Soil Moisture Meter more often to check the soil condition, remember to keep the soil moist but not soggy. Water after the top 1.5-2 inches or so of soil has dried out and build the watering schedule for your Polka dot begonia by continually testing. Potted plants are more prone to being overwatered than their outdoor counterparts since it's easier for the water to become contained. Make sure you use a pot with proper drainage holes and well-draining soil. Make sure there’s no excess water in the plant tray before watering. If your Polka dot begonia is planted in the ground, rain will allow it to grow better. The Polka dot begonia usually needs about 1 inch of rain per week to maintain growth. If rainfall is low, you may need to do additional watering once a week to ensure proper plant growth. Humidity also plays a role in keeping the plants properly watered. Plant can grow in normal room humidity, but it prefers higher humidity if possible - generally around 40 to 60 percent. More humidity means the soil will stay wetter for longer. With indoor plants, you can increase the humidity by placing a small humidifier next to the plant. For outdoor plants, you can mist the plant throughout the day.

There are plenty of viable ways to supply your Polka dot begonia with water. If you grow your plant in an indoor pot, for the Polka dot begonia in small pots, you can bring your potted plant to your kitchen sink. Then, use the faucet to add water to the container. By holding the pot in your hands, you should easily notice when the water begins to run through the pot’s drainage holes, at which point you can stop watering. The cold temperature will hurt the plants' root system, so please don't do this during winter or in cold climates. Most of the time, watering via your faucet is permissible for the Polka dot begonia. However, if the local tap water contains a high proportion of fluorine, chlorine or salts, you should consider using rainwater or lake water. Also, since the Polka dot begonia can respond well to overhead watering and watering directly into the soil, you can use a watering can, hose, or just about any tool you’d like to water it. For Polka dot begoniaed in the ground, when there is not enough rain, aim the hose at the root system and open the spout for more than 10 minutes to fully water. Tips: The Polka dot begonia is quite sensitive to the water you use. They are used to soft, acidic water found naturally. If you live in an area with hard water you can use an at-home water filter to remove any minerals and salts. To get rid of chemicals, you can let your tap water sit out for around 24 hours so that they dissipate. You can also purchase filtered water for your plants. Polka dot begonia likes water with 6.5 pH the best. Rainwater is a better choice than tap water, so you can store some rainwater when it's raining for your Polka dot begonia.

Polka dot begonia needs the humid conditions tend to keep the plants moist. They do not dry out completely between waterings. However, if soggy is retained, it will tend to make its root system rotten. So people will always water after the top 1.5-2 inches or so of soil has dried out. The depth of testing is often related to the depth of the soil. When the soil depth is around 5 inches, it is recommended to test about 1.5 inches or so (about one-third of the soil depth), and more for larger pots. If you have a Soil Moisture Meter, then watering becomes easy by inserting the same position and when the soil meter is found to be around 3, then watering can be done. If it is still greater than 3 then you will need to wait a little longer until it dries out. Keeping it this way will allow you to avoid overwatering your plants.

It is helpful to lightly prune this plant periodically during the spring and summer. When performing this light pruning, you should search for leaves that have wilted, become discolored, show signs of disease, or have died completely. Remove dead or damaged leaves by cutting their petioles, or trimming off stems that have died. This will increase the light and ventilation of the plant and help it to grow. Some gardeners also choose to remove the flower buds of the Polka dot begonia. However, removing flower buds before they open is a strictly aesthetic decision that will emphasize the beauty of this plant’s showy leaves.

You can prune your Polka dot begonia 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.

Pruning the Polka dot begonia 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.

Since pruning for the Polka dot begonia should take place periodically throughout the season, what you do after pruning can vary. For instance, if you prune to remove selected leaves and stems from your Polka dot begonia, you won’t need to do anything except continue your regular maintenance routine. At times, you may choose to remove healthier leaves and include them in a display of cut flowers and foliage. However, there is no crucial maintenance task to perform for this plant after typical pruning. The only thing to note is that when watering after pruning, you need to be careful not to touch the wound to prevent fungus from infecting the plant through the fresh wound. Placing Polka dot begonia in a well-ventilated location will also help the wounds to dry out and heal in time. The timely replenishment of Polka dot begonia after pruning will help the Polka dot begonia to recover as soon as possible.

For your major pruning, use sharp pruning sheers that will make clean cuts to avoid damaging your plants. As you are pruning your Polka dot begonia, 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 symmetrically. If the overall growth of the plant is weak, the flowers need to be pruned back in time for flowering to be able to save nutrients for leaf growth and allow the plant to grow more vigorously.

Polka dot begonia typically needs full, indirect sunlight in order to thrive indoors. This means that the plant should be exposed to bright sunlight that doesn’t hit it directly from a window or another light source, like a grow light. You can easily protect it from direct sunlight by placing a sheer curtain between your Polka dot begonia and the window, or by placing it behind a part of the window with a dark screen.

If this is your first time bringing your Polka dot begonia home, then it might be a good idea to try to ease it into the sunlight it needs, rather than place it in bright, indirect light right away. Over the course of two weeks or so, you can slowly move your plant into the sunlight to avoid shock or burning of the leaves from sudden intense light exposure. By easing it into the light, your Polka dot begonia is much more likely to adapt to your home environment well.

Polka dot begonia is one that can easily sunburn with too much sunlight. In the wild, these plants only receive mild, dappled light, filtered down from tree canopies. While they need more light than that to grow in our homes, too much can certainly cause issues. If your Polka dot begonia is getting too much light, you’ll notice that the foliage begins to look bleached or washed out, the tips of leaves may turn yellow or brown and crispy, and it may even grow too quickly to support itself.

Sunburn for plants is much less severe than sunburn for people. While it may look unsightly, crispy, burnt leaves can be removed if they’re too far damaged to recover, or over half of the leaf is damaged. However, you can also try trimming back the leaves just to remove any sunburn damage in an effort to save them, if there’s not too much discoloration. Move your Polka dot begonia away from its light source to avoid future light damage.

While some plants may be ready to face the sweltering sun straight out of the ground, Polka dot begonia needs some time to build itself up enough to tolerate bright light. Propagated cuttings should receive only moderate indirect light, while new leaves during the growing season should be shielded a bit as well. The tender new leaves are more prone to sunburn than any other part of the plant.

Fortunately, plants can communicate in their own language to convey whether they have adequate sunlight or not. Like most plants, your Polka dot begonia will tell you if it isn’t getting enough sunlight. The most visible sign is when your plant becomes particularly dark, or there is no new growth on the plant from one season to the next. You’ll also notice that leaves that do grow in may remain smaller than others, since there isn’t enough light to photosynthesize to support large new leaves.

Depending on how bright the sunlight is that your Polka dot begonia gets, the number of hours in a day may vary. If you have your plant in bright, indirect light, then there’s no need to try to restrict or increase the amount of time your plant gets this light each day. However, if light is less bright or further away from your Polka dot begonia, then you can try to aim for at least eight hours of full light per day.

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 Polka dot begonia 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.

Polka dot begonia 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 Polka dot begonia 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.

All plants rely on soil nutrients to facilitate their growth, and the Polka dot begonia is no exception. However, it is not always a guarantee that the soil in which your plants grow will have all of the nutrients required. Fertilization and soil amendments help ensure that the plants in your garden not only have the basic nutrients they need but also that they get the nutrients that are specifically necessary to them. Polka dot begonia needs fertilizer to ensure that its roots and stems continue to develop in a healthy way throughout the growing season. Fertilization will also help a Polka dot begonia a set of leaves that looks fantastic, which is especially important for this plant since its foliage is its main point of ornamental appeal.

A Polka dot begonia will need the greatest amount of fertilizer during the seasons in which it is actively growing. This active growth phase typically spans most of the months that make up spring, summer, and early fall. Once winter ends, you should plan to feed your Polka dot begonia about once every two to four weeks. Continue feeding at this rate until the fall months arrive. Once fall arrives, you can reduce your fertilization rate, reducing the amount of fertilizer you give gradually until you cease feedings entirely in anticipation of winter, when the Polka dot begonia will have far less active growth.

Throughout most of the year, including spring, summer, and most of the fall, you should continue feeding your Polka dot begonia regularly. The only exception to this is if you notice that your Polka dot begonia has received too much fertilizer or if you have managed to fertilize your Polka dot begonia incorrectly, causing fertilizer burn or some other issue that you'll need to remedy before returning to a regular feeding schedule. The only time of year when you should not fertilize a Polka dot begonia is during winter. If you grow this plant indoors in an area where the winters are cold, it will enter a dormant phase during the winter. Feeding this plant during its dormant phase is not only unnecessary and unhelpful to this plant's growth, but it is also very likely to cause fertilizer burn.

The fertilizer for a Polka dot begonia has a specific blend of nutrients, each of which is present in relatively low amounts. An ideal fertilizer will have an N-P-K ratio of 3-1-2. However, a general-purpose fertilizer that has an even blend of nutrients can work well in some cases. Still, even when using a balanced fertilizer, the ratio number representing the volume of each nutrient should be at 10 or lower. The fertilizer you use can be either granular or liquid based. If you choose to use a liquid-based fertilizer, it is often best to dilute the strength by half. While there is not much downside to granular fertilizer, it is often most sensible to use liquid fertilizer, especially if you feed your Polka dot begonia while you supply water.

The fertilizer that you purchase for your Polka dot begonia will likely come with application instructions that you should follow in most cases. However, for a Polka dot begonia, you should always fertilize just before or while you are watering the soil, as this will prevent the fertilizer from burning the plant's roots. If you use a slow-release granular fertilizer, you should sprinkle it on the soil and then provide water immediately after. If you use a liquid-based fertilizer, you should dilute it with water, apply it to the soil, then supply a bit more water. Diluting your fertilizer by at least half is especially important in spring and fall when the plant's growth is ramping up and decelerating, respectively.

Since it is advisable to fertilize your Polka dot begonia every few weeks throughout the growing season, overfertilization is not often an issue. However, it remains possible for this to occur. If you overfertilize your Polka dot begonia, you may notice accumulations of excess fertilizer on the soil’s surface and foliage discoloration. Fertilizer burn is the most common issue you should worry about when feeding a Polka dot begonia. This issue occurs when you overfertilize, fail to dilute your fertilizer, or when don’t water during and after fertilization. In any of those cases, the fertilizer can draw moisture out of your plant’s roots, causing it to dry out. Often, fertilizer burn will manifest with browning and yellowing of this plant’s leaves.
