Alocasias are fantastic plants for the garden or home. Native to Southeast Asia and Australia, they are used to warm temperatures year round and must be overwintered in pots or dug up and stored as bulbs in a cool, dry place in all but the warmest climates. Regardless of how you grow them, though, fertilizing alocasia plants is essential to their healthy growth. Keep reading to learn about alocasia plant feeding and when to fertilize alocasia.
Alocasia plants have the potential to become enormous. If overwintered successfully for multiple years, they can reach 10 feet (3 m.) in height and produce leaves that are 3 feet (1 m) long. The key to growing such stunning plants is fertilizer.
Alocasias are very heavy feeders, and fertilizing alocasia plants frequently is the only way to keep up with their appetite. Before planting your alocasias, mix 2 pounds (1 kg.) of slow-release fertilizer per 100 square feet (9.5 sq. m.) of soil.
Keep up regular fertilization every two to four weeks.
Is feeding alocasias really necessary if you’re growing them indoors? Chances are you want your houseplant somewhere under ten feet (3 m.) tall. The thing about fertilizer, however, is that it isn’t just for rapid growth. Kept in a pot, your alocasia almost certainly won’t reach its full potential size, but it still needs regular fertilization, perhaps even more so.
Because of the small amount of soil in a container, nutrients can be washed away more easily. With every watering, add a little water soluble fertilizer to keep your alocasia plants growing healthy and strong.
If your alocasia’s leaves start to appear burnt, however, it probably means you’re applying too much fertilizer. Flush the container with plenty of clean water until it runs out of the drainage holes and cut back on your fertilizing regimen.

When it comes to the natural beauty of Alocasia Amazonica, also known as Alocasia Polly, it is all about the elaborate tropical foliage. When grown in preferred conditions and given proper care, this hybrid Alocasia will grace your indoors with its lush growth and distinctly colored leaves for years to come. Below we have listed a brief outline of their care for the best performance and healthiest growth.
How To Care For Alocasia Amazonica: Grow in lightweight soil that drains well and water when the top of the soil begins to dry. Maintain moderate humidity, place in a bright location with indoor temperatures between 65°F and 80°F and fertilize every two to four weeks during the growing season.
Whether you are new to growing Alocasias or are just adding a new variety to your indoor collection, continue reading because we’ve taken all the mystery out of properly growing an Alocasia Amazonica.
There are various possible reasons behind your Alocasia’s leaves curling. Most of them are related to improper care and environmental issues.
Don’t worry if you are not sure which one your plant is dealing with. I will go through all the reasons that could cause the leaves curling, and you can learn how to improve your Alocasia’s life.
Since Alocasias are tropical plants, moisture is very important for them to survive. Proper watering and regulating moisture is an important step in Alocasia plant’s care.
It is important to keep the soil moist and not soaking in water. However, if you stop watering your plant regularly, it often leads to the curling of the leaves.
If your Alocasia plant is dealing with an issue of under-watering, its leaves will start drying out and will become crispy. That will further lead to curling of alocasia leaves.
Fixing this issue is simple and easy. All you need to do is learn how to water your Alocasia plant properly and adapt your watering routine.
Alocasia plants love moisture and they thrive when the soil is wet. It is important not to over-water your plant, of course, but to still keep it moist.
Watering your Alocasia once a week should be enough for it to thrive. However, if you want to track the moisture of the soil, I would recommend you use a moisture meter.
Keep in mind that Alocasia plants are in a dormant stage during winter. That is why you should water your plant less during this period, as it requires less water.
Pests and insects infest all plants, even the indoor ones. They are annoying to deal with and always find their way back.
Alocasia plants are mostly prone to mealybugs and spider mites infestations. Insects can cause a lot of issues, such as damaging the plant cells, damaging the whole plant by sucking the juices, or even killing it off completely.
When it comes to Alocasia plants, it is often the case that insect infestations lead to the curling of the leaves.
The best way to get rid of the insects is to first find out why they are attacking your plant. From there, you can get to fixing the issue and saving your plant.
Make sure that your plant has no dust on it. Insects love dust, so try showering or simply dusting off your Alocasia plant from time to time. This will prevent them from infesting your plant again.
To get rid of them, you should try using neem oils. This will remove the bugs and prevent them from inhabiting your plant.
If you cannot provide your plant with this type of oil, there are various sprays you can try. They will also eliminate the bugs as well as their eggs.
Although you’re keeping your Alocasia plant in a pot, it will still need regular fertilization. It won’t grow to its full size, but it needs fertilizers to thrive.
However, it is important to keep it safe and not over-fertilize your Alocasias. Over Fertilizing can burn the root system which will ultimately affect the whole plant.
Excess nutrients will damage the leaf cell and will have burnt look. It is one of the most common reasons behind their leaves curling.
Alocasia plants are hungry plants and they require regular fertilization. You should feed your Alocasia plants once every two weeks, only during the growing season.
As it is the case with most plants, it is important not to fertilize Alocasia plants during winter. That is the period when your plant is not growing and therefore has no need for additives.
Using a regular water-soluble fertilizer during spring and summer will be enough for your Alocasia plant.
If your plant’s leaves start to dry and curl, it probably means you are over-feeding them. If this happens, you should water your plant thoroughly, let the water drain out, and slow down with the additives for a little bit.
Potassium deficiency in Alocasia plants reflects in curling and drying of the leaves. They usually affect lower and older leaves first.
If you suspect that your plant is dealing with potassium deficiency, don’t worry. There is a way to treat it and I’ll help you learn how.
The easy way to fix this is with potassium fertilizers. The best fertilizers for your plant would be the ones rich in potassium chloride, potassium nitrate, potassium sulfate, and monopotassium phosphate.
If you prefer using organic fertilizers, try feeding your plant with seaweed, compost made of banana peels, or comfrey liquid. Whatever option you choose, make sure to supply enough water to uptake all the necessary nutrients.
Alocasias are tropical plants and they cannot survive in low temperatures. If you live in an area with a cold climate, your plant might deal with leaves curling if you don’t give her some special care.
Alocasia can not tolerate temperature below 10°C/50°F. It thrives well between 20-30°C/ 68-86°F temperature range.
Alocasia plants prefer warmer temperatures. If your plant’s leaves start to curl, maybe you should consider placing it in a room with a higher temperature.
Overwatering your Alocasia plants commonly leads to root rot. If the leaves start to curl or develop brown spots, it is often an indicator that your plant is suffering from this issue.
Watering your Alocasias can be tricky. They love humidity and their soil to be moist, which is why plant owners usually over-do it.
Keep in mind that Alocasia’s soil should be damp, but now flowing in water. If your plant starts showing the signs of root rot, it is time to give her some special care.
Make sure to remove the damaged leaves first. Cut off the rotten roots with a sterilized scissor. After that, let the accumulated water drain out completely.
Ideally, you should re-pot your plant and change up your watering routine. If you choose to do this, make sure to make the soil a little more drainage-friendly. Try adding peat moss to the mix.
Water quality is important when it comes to plant care. For the house plants especially, it is very harmful to use tap water.
Tap water contains minerals and salt, which is why it is often called ‘hard water’. Substances such as these lead to a buildup in the soil. The buildup of the minerals then prevents the plant to absorb water which causes the leaves to curl.
To prevent this from happening, it is best to use filtered water for your Alocasia plant.
There are numerous water filters you could buy which will filter out your tap water for you, and it is an easy way to produce a mineral-free one.
If water filters are too pricey for you, you can always buy filtered water and keep it on a side for your plants. It will be less pricey and will give you the same result. You can also consider collecting rainwater for your houseplants.
Although Alocasia plants are tropical and prefer to be in bright places, too much light can do more harm than good, one of the issues being curling of the leaves.
Excess light creates energy more than your plant can handle. Then it shows symptoms like curling leaves. It is important to balance it out and to find a middle ground when it comes to lightning.
Alocasia plants need to get plenty of sunshine. Although they need more than most of the other houseplants, the light should be filtered.
Since it is easy to stress and burn the leaves with too much light, it is important to keep them in the filtered sunshine for about 6 to 8 hours a day.
If you find the right spot, your plant will thank you with beautiful and healthy green leaves. You can consider using a curtain to filter the direct sunlight.
If there is one thing that tropical plants need – it is high levels of humidity. Therefore, your Alocasia plant will need it, too. This is often a problem for plant owners during winter.
Lack of humidity causes the plant leaves to lose more water. So there will be a lack of water within the plant cell. Besides other issues it will cause curling and drying of the leaves.
That is why you should make sure to provide your Alocasia with enough moisture.
You should always keep the air around your Alocasia plants moist enough. A humidifier will be your best friend, especially during winter. You can keep plants together to keep the humidity level high.
Make sure not to moisturize your plant by misting. Wet leaves often lead to fungal infections and you will give yourself even more issues to deal with. Using humidifiers is the way to go!
Keep your plant warm, keep it away from the air-conditioned rooms, and give her enough humidity. It will love you for it!
Although they can be outdoor plants, it does not necessarily mean that they prefer large pots. If the pot size is small then the root system of your alocasia can not spread.
Then it can not intake water and nutrients properly. So Wrong pot size can also lead to the curling of the leaves when it comes to your lovely Alocasias.
Alocasias like to be root bound. That is why you don’t have to rush and put them into larger pots once the root bounding begins.
When you decide that it is time to put your plant into a larger pot, make sure that you don’t change the pot size drastically.
You want to keep your Alocasia plant happy and to settle in her new home quickly.
How to Prevent Alocasia Leaves Curling
◙ Learn how to water your Alocasia. You are taking care of a tropical plant, which means you need to keep its soil moist at all times. To keep it healthy, make sure to use filtered water instead of the hard one.
◙ Give it light! Your Alocasia plant will thrive in bright places. However, don’t over-love it. Filtered light for about 8 hours a day will be just enough.
◙ A humidifier is your best friend. It is important to provide your alocasia with enough humidity. This tropical plant loves highly humid places, so make sure to use a humidifier around it.
Alocasia stingray needs bright filtered light for good growth and vibrant leaves. So, the best place for the plant will be a west-facing window.
If the direct sun rays are coming from the window. Then you need to install a curtain between the window and the plant. This will prevent the direct fall of sun rays.
If you do not want to use a curtain. In this situation, you should move the plant a few feet away from the window.
The last thing you can do is use artificial growing lights. Nowadays we have many options in the market.
Out of them LED grow lights are more useful and highly efficient.
They emit a light spectrum that is similar to the sun rays. The plant cannot differentiate between the light emitted by the sun or LED light.
200 watts grow light is perfect to grow 1 to 2 alocasia stingray plants.
For Alocasia stingray care water, it 2 times per week in the summer season. Whereas it needs less water on winter days.
Before watering regardless of the season, you should check the condition of the potting soil. Pour some water only if the top 2 inches of the soil are dry.
Water the plant until the water comes out of the draining hole. This technique keeps the soil moist for a long period of time.
Filtered water is best to use. Because tap water may contain chlorine. Water authorities add it to the water to kill the harmful organisms in the water. This type of water is not recommended for Alocasia stingray care.
Soft water free from heavy minerals is a perfect choice.
This plant needs a warm temperature. Maintain the temperature between 18 to 26 degrees C. If it drops below 12 degrees C. The plant can survive in it. But once the temperature drops below 12 degrees C.
Then the cells in the plant leaves start freezing and dying. This process continues until you adjust the temperature to the correct range.
Sudden high temperature causes leaf curls and makes them dry. Low temperature triggers yellow leaves.
Temperature also affects the nutrition absorption rate of the roots. Sudden fluctuations give a shock to the plants.
You need slightly acidic soil. The pH of the soil should be between 5.5 to 6.5. The best mix would be
1part garden soil + 1 part perlite + 1 part peat.
This mixture together from a good draining soil with excellent aeration qualities.
Such soil can save the plants if you forget them to water. Because the perlite has the ability to store water contents for a long time.
Your plants need high humidity than the normal range. This means you have to work more to keep the room-air well moist. One simple solution is using the humidifier. This can be expensive for some growers. Do not worry we have some affordable yet powerful techniques.
Fill a normal tray with water and put some small stones in it. Then put the plant pot on it. This will increase the humidity. Because when the water in the tray gets evaporated it will make a balance of air moisture around the plant pot.
The last method is misting water on plant leaves on hot days and grouping the plants. By putting all plants close together you can build a humidity balloon around them.
Occasionally misting water on plants keeps the plant temperature in control.
Note: Humidifier is the best and instant solution to low humidity.
10-10-10 formula will do best for the stingray plants. To speed up the growth give fertilizers to the plants in their growing phase. Spring to August is the right time for fertilization.
You need to give a nutrient boost to plants once every 3 weeks. Liquid fertilizers are recommended. Because they are easy for the plants to absorb. They do not create any salt build-up in the root area.
Highly fertile soil is required therefore you need to add compost-like substances to the soil. If you are using pre-fertilized soil. then you don’t need to fertilize plants. Because such contains all the essential nutrients.
It is slightly costly than the normal potting soil.
If you grow this plant in USDA zones 9b to 11 then you need to surely trim it. Because due to the perfect temperature they might not go to their resting period.
Wear the gloves and sterilize your tools.
Closely observe the plant and look for signs of damage
You have to remove them first and then move to the overly grown parts.
Yellow leaves brown-spotted leaves need to be removed.
All parts of Alocasia are poisonous and can be fatal if ingested. Initial symptoms may present as paralysis of mouth and throat after eating and difficulty speaking, nausea, diarrhea, delirium. Alocasia can also cause severe skin irritations, so wear gloves when handling the plant.
Alocasia is the name of a large family of tropical herbaceous perennial plants that are grown primarily for their dramatic foliage. Commonly called elephant's ear, alocasia colorations, leaf patterns and overall plant size vary greatly by cultivar but they all thrive in partial shade conditions outdoors and bright indirect light indoors. All elephant's ear plants are grown from and reproduce with underground rhizomes.
Plant alocasia in outdoor locations where they will receive filtered shade and grow indoors in a location where they will receive bright indirect light. Choose a planting site that will easily accommodate your variety of alocasia at maturity as they do not respond well to being moved after they have established themselves in a location. Keep the soil rich in nutrients by mulching with one or more organic materials such as compost, leaf mold, shredded bark or cocoa hulls. Mulching will also help prevent moisture lost to evaporation.
Water your alocasia regularly so that the soil around the rhizome is always moist. Do not allow the soil to ever dry out. Judge when it is time to water by dipping your fingertip an inch into the soil. If it feels just barely moist it is time to water. If you are growing alocasia in a container of any kind, make sure that you have plenty of drainage holes so that the soil does not become saturated. Excess water can rot the rhizome.
Feed alocasia once a month with a general purpose water soluble houseplant fertilizer such as Miracle-Gro. Apply the formula onto wet soil at half the recommended dose. Alocasias are not heavy feeders and the rhizomes can be damaged by a build-up of fertilizer mineral salts.
Prune away any damaged, diseased or dying stems and leaves when you see them by cutting the stem down to the plant base with clean, sharp secateurs. Other than removing damaged stems and pruning to control size, alocasias do not require pruning to spur growth.
The alocasia frydek enjoys bright, indirect light. Just as importantly, it doesn’t do well with either extreme.
The worst place you can put it is under direct sunlight. While it can tolerate up to 1 to 2 hours per day of this, it will struggle then suffer if exposed for longer periods. You’ll see its leaves get scorched and brown spots start to appear. Its leaves can likewise turn yellow or pale in color.
Needless to say, you don’t want to keep the plant under the sun’s rays for long periods of time. This means in west, south and east facing windows, it is a good idea to keep the plant a few feet from the opening. Of the three, the east has more gentle sunlight. So, it has less of a sunburn risk for your plant.
On the other hand, low light isn’t as bad. But, it will still hamper the growth rate of your plant. As such, it will take longer for leaves to form. And, in many cases, the leaves and plant will be smaller. In dimmer conditions, your plant will look weak and kind of malnourished.
However, don’t be alarmed if the plant’s growth slows during the winter. For first time owners, this may look like a problem. However, the lower light and cooler temperature of winter causes the plant to go into its dormant state. Once spring comes, it will bounce back.
For the time being (in winter), scale back on watering and stop feeding
The best temperatures for your alocasia frydek is between 65 and 85 degrees Fahrenheit. It also enjoys consistency. As such, it is a good idea to keep the plant somewhere nighttime temperature doesn’t drop too far off from the daytime.
Additionally keep it away from openings where cold drafts can suddenly come in. Vents that produce warm or cold air are likewise no-no’s. So, you want to keep it away from heaters and air conditioners as well.
If exposed to these conditions, you’ll see its leaves turn yellow while some with die. The plant will likewise start wilting.
The good news is, most homes have temperatures that fit into the range. Once the temperature drops under 60 degrees, the plant may go into dormancy. During the winter, this is its natural cycle (and come back to life in spring). But, you don’t want to let this happen at other times of the year.
Humidity is another important factor needed for proper care of your Green Velvet Alocasia. Ideally, it likes humidity to stay above 50%, which can be a problem for many homes.
The average home’s humidity hovers between 40% to 50% for most of the year. In wintertime, it drops under 40%. As such, you want to be able to bring up that level, even if it is just around the plant.
Low humidity can damage the plant causing brown leaf tips and edges.
Thus, when taking care of tropical plants, it is a good idea to get a hygrometer, which is a device that measures humidity. This lets you know if you need to take extra measures to increase air moisture.
If you do, here are the simplest ways to do it. I recommend the free and hands-off methods more so it doesn’t cost you thing. Plus, once you set them up, you won’t need to do regular maintenance often.
Other options that work also include the following. But, they do have more drawbacks.
Like other alocasias, the most challenging thing about caring for the green velvet is watering. To thrive, they need moist soil. But, you need to be careful not to over do it because the plant struggles with wet, soggy soil.
This balance is what makes things complicated.
During the warmer months when the plant is actively growing, let the top 1 to 2 inches of soil dry before watering again. This is a much better way than following a time-based watering schedule as climate and other conditions affect how quickly the soil dries.
Additionally, it is important to note that the plant has thick stems and foliage. This allows it to store water much like succulents do. But, unlike succulents, it isn’t drought tolerant. So, you need to tow the line between too little and too much water.
Once the weather gets cold in the winter, you’ll want to switch up your strategy. Because the plant despises overwatering, you want to be more careful here. The cold weather and the plant’s dormant state means soil will take much longer to dry.
As such, dousing with deep watering is not a good idea. Instead, you want to water a little at a time. Then add as needed.
This is not the most efficient way to water for a few reasons.
That said, it is a good method to prevent overwatering which can kill your plant. So during this period in its growth cycle, it’s the best solution. Then return to a more regular watering strategy come springtime.
From the previous section on watering, you can already guess that well draining water is key to the plant’s good health. In addition, the Alocasia Frydek also likes rich soil.
Thus, a peat based potting mix that drains quickly is a good options here. You can likewise use coconut coir if you want something more sustainable. In case you want to create your own recipe, taking advantage of perlite will help it drain moisture faster.
Whichever substrates you decide to use, make sure that it can retain some moisture as well. This will allow the plant to absorb the water and nutrients it needs.
During its growing season between spring and summer, feed the plant with a balanced water soluble fertilizer diluted to half strength every 2 to 4 weeks. The plant likes to feed more than other houseplants. So, want to give it enough to grow.
However, it is important not to overdo it. That’s because as much as fertilizer helps the grow, too much of it is toxic to your plant. When it received too much, it will experience fertilizer burn.
Alocasia Green Velvets don’t need a lot of pruning. Here, you only need to trim the old, damaged or yellow leaves.
In its natural growth cycle, the plants will produce new leaves every so often to replace the old and wilting ones. As such, if you see brown, drooping foliage, it doesn’t always mean there’s a problem. But, you need to be abel to tell the difference between its natural aging process and health issues.
In the case of the latter, you’ll want to investigate and quickly fix the problem.
Division is the best way to propagate your Alocasia Green Velvet. And, the best time to do so is during the spring or summer. This allows the new plant to start growing right away.
Also, it is a good idea to propagate when you repot the plant. This way, you do both at the same time.
Here’s how to propagate Alocasia Frydek via division.
You won’t need to repot your alocasia frydek more than once every 2 years. And, the only time you need to do so is when it is rootbound. A few ways to tell include:
Additionally, the best time to repot is during the spring or early in its growing season. This allow the plant to take advantage of the fresh soil and bigger pot to grow.
When choosing a new container, make sure it is just slightly bigger than the original pot. Since the plant is susceptible to overwatering, you don’t want a lot of soil relative to the plant. On the contrary, the alocasia frydek prefers the opposite.
If you’re planning to propagate your green velvet, this is likewise the time to do so.
Here’s how to repot your alocasia frydek.
Gently take the plant out of its container. The more rootbound it is, the harder it will be to remove from the pot. But, don’t jar or shake it hard to speed things up. This only increases the shock the plant experiences.
One way to make it easier to take the plant out of the container is to water the plant a day or two before you plan to repot. This softens the soil a bit to make it easier to slide out of the container.
When you have the plant out inspect the root ball.
Here, you’re looking to remove excess soil and dirt. You also want to spread out the roots. And, if needed trim away any mushy roots.
Fill the new pot with fresh potting mix. Ideally, you want enough soil underneath so the plant will stand at the same height as it did in the old containers.
Insert the plant into the new pot and add the remaining potting mix to fill the container.
Water he soil and place it back there it was.
The Alocasia Frydek is a plant you do not want kids and pets playing with. It is toxic when ingested because of its calcium oxalate crystals. These can cause irritation and swelling in your mouth, throate and digestive tract.
Similarly, you want to wear gloves when working on the plants as it irritates the skin upon touch.
Most of the problems that happen to the Alocasia Frydek are related to overwatering. The biggest and most dangerous one of all being root rot. Additionally, excess moisture allows bacterial and fungal diseases to develop.
As such, it is important to consider the following:
When it comes to pests, your Alocasia Frydek attracts mealybugs, thrips, spider mites and aphids. Thus, it is important to check your plant regularly for any signs of pest infestation. If you do find them, quickly separate the plant from the rest and start treatment.
Also, make sure to check the nearby plants to see if the pests have spread to them.
Alocasia Stingray is considered rare for its unique form of tropical Elephant Ears. Wherever room you want to put it, it adds an exotic touch. The stem is considered unique with its mottled pattern similar to Alocasia Zebrina,
It is very eye-catching. It’s rare yet on-trend because of its exceptional feature.
Allow the top 2-3 inches to dry between watering to ensure that your Alocasia Stingray isn’t going to be overly soaked in water.
During winter, it will take longer for the soil to dry due to cold temperatures. This time, you need to reduce the watering frequency.
