Anthuriums are known for their enduring, heart-shaped blooms. The colorful, magnificent blossoms add a wonderful pop of color to the house and are quite simple to maintain!
If you have bright shade, anthuriums are a fantastic option for an outdoor summer container as they thrive in the heat and humidity and should bloom all season.
Light:
Anthuriums will grow and survive in low light, but they won’t blossom because they need medium to bright light to bloom. Select a location that receives some sunshine but is not directly in the sun (early morning or late afternoon sun is generally OK).
Water:
Keep the soil barely damp but not drenched. In the spring and summer, the plant will require extra water, especially if it is in direct sunlight. Root disease may result from overwatering and be challenging to treat.
Use any all-purpose fertilizer ideal for indoor plants to fertilize in the spring and summer. You can achieve excellent results by fertilizing at a diluted rate (often 1/4 strength) with each watering, and you won’t need to keep track of when you last fertilized. It also works well to use a slow-release fertilizer like Osmocote.
Heat Index and Humidity:
Regular home temperatures are excellent, but like many tropical houseplants, summertime outdoors brings additional heat and humidity that feels “exactly like home.” If you decide to grow your Anthurium outdoors, just be sure to keep it away of direct sunlight.
Do not place your Anthurium too close to a heat source or in a hot or cold draft. This may cause the leaves to dry out and develop brown tips.
Repotting:
Repot your Anthurium in the spring when the roots are starting to grow if it is outgrowing its container. Any high-quality, well-drained soil mixture will do.
Anthuriums develop an extended stem with exposed root nubs as they get older. These stems can be wrapped in wet sphagnum moss, tied, and covered with a thin piece of plastic to keep the moisture in. The roots should start to develop into the moss if you keep it moist. Once a significant number of new roots have grown, the stem can be severed at the soil line and the newly developed roots potted.
Anthuriums should continue to bloom for nearly the entire year as long as they receive enough light, moisture, and fertilizer during active growth. If your Anthurium isn’t blossoming, it’s probably due to a lack of moisture or light.
How long must it be light for anthuriums?
Bright, filtered light is necessary for flowering anthuriums because direct sunlight will burn the leaves and blossoms. Low light will inhibit growth, mute the color, and result in fewer, more modest “flowers.” A location where your anthuriums will get at least 6 hours per day of bright indirect sunshine is ideal.
Where should an anthurium be placed?
The anthurium enjoys being situated in a bright area, but not in the sun. Because the plant’s leaves may burn if it is placed in direct sunlight. Because the anthurium prefers warmth, avoid placing it in a dark location where it will produce fewer blossoms. Avoid placing your plant near a hot radiator and keep it away from draughts. An anthurium flowers best when the temperature is between 20 and 22 C.
Low-light anthurium growth is possible.
Although anthurium plants can withstand all intensities of indirect light, those that do so will produce fewer flowers and develop more slowly. However, because direct sunlight can burn the leaves, these plants cannot tolerate it. Bright, directed light is optimal for their growth.
The soil must be free draining but retain some water in order to properly care for anthuriums. An equal mixture of potting soil and orchid soil or perlite will give the type of soil that anthuriums prefer if you are growing this plant as a houseplant. Plant outside in a spot that has good drainage. Anthurium plants dislike soil that is constantly wet.
Don’t overwater your anthurium plant, but be sure to water it frequently. Anthuriums should only be watered when the soil feels dry to the touch. Too much water may kill the roots because the plant is prone to root rot. The rootball will be challenging to re-wet if you let the plant’s pot become too dry, which will slow down its growth. If the rootball in the pot gets too dry, give the anthurium plant’s container an hour in the sink to rehydrate it.
Anthurium plant maintenance doesn’t call for a lot of fertilizer. Once every three to four months, the plant only needs to be treated with a fertilizer that is 1/4 strength. Use a fertilizer with a greater phosphorus amount to produce the best flowers (the middle number).
Anthurium care is simple and straightforward. Watering is easy after the plant is in the appropriate soil and location. Your home or garden will benefit from having an anthurium blooming there by producing lovely, long-lasting flowers.
Does anthurium tolerate shade?
Anthuriums thrive in the controlled conditions of the house when provided with frequent waterings, steady temperatures, and indirect sunlight. Anthurium is particularly sensitive to the cold and requires consistent temperatures between 60 and 90 degrees F (15-32 C) in order to thrive. It is hardy to zones 10 or higher. Outdoor anthurium plants may suffer harm when the temperature falls below 60 F (15 C).
Anthuriums also need regular watering and soil that drains well. They are vulnerable to root rot, crown rot, and fungi infections if they remain in moist, squishy soil for an extended period of time. Anthuriums require filtered indirect light or partial shade. They can become scorched by too much sunlight, and they can lose their elegant spathes and spadixes if there is insufficient light. They also dislike being outside in windy conditions.
If temperatures in your region can drop below 60 degrees F when growing anthuriums outside, it is preferable to grow them in containers that can be transferred indoors (15.5 C.). Additionally, it’s crucial to fully hydrate the root zone and then let the soil dry up in between waterings. In partially shaded places, where the soil tends to stay moist and soggy, this isn’t always simple to perform. Organic soil amendment and peat or Spanish moss mulching around the plant can also be beneficial. However, never let the plant crown of an anthurium be covered by earth or mulch.
The majority of the nutrients that anthuriums require should come from the organic matter they are grown in. If you decide to fertilize outdoor anthurium plants, do it just once every two months with a phosphorus-rich fertilizer.
Planting anthuriums in areas where children or animals congregate is not advised since several types are toxic or contain oils that can irritate the skin.
How are anthuriums kept from blooming?
Anthuriums are renowned for their extravagant, exotic flower bracts, which frequently bloom all year long and appear in vivid hues of red, pink, and white. Therefore, it can be very upsetting if your anthurium isn’t flowering while generating foliage that seems healthy.
Why isn’t my anthurium in bloom? Since anthuriums are fussy about their surroundings, problems like wet soil or inadequate illumination might keep them from flowering. By giving your anthurium plenty of indirect sunlight, appropriate watering, high humidity, and weekly feedings with diluted phosphorus-rich fertilizer, you may encourage it to bloom.

How often should anthuriums be watered?
H2O and Humidity
Low to medium water requirements apply to this houseplant. In between waterings, let the soil to dry out. If you reside in a hot climate, water your lawn once every two to three days; if it rains frequently, water as needed. The anthurium needs appropriate drainage most of all.
What exactly is dazzling indirect light?
In conclusion, brilliant indirect light is bright enough to read by and to cast a shadow, though not a dark, distinct one. It can be found a few feet away from south- or west-facing windows that are not sheltered, as well as close to windows that face north and east. Additionally, it can be produced by placing plants on windows that receive direct sunlight and diffusing sheer white curtains—the kind you can see through—between the glass panes.
In rooms or corridors without windows or if plants are placed in corners more than 5 feet from windows, bright adequate light for houseplants is probably not going to be present. You can use fluorescent or LED grow lights to produce bright, indirect light for such locations.
The best way to create bright, indirect light for your plants is by using your windows and the direction of the sun throughout the day.
Your windows’ orientation and how clear they are of obstructions both affect how much light your plants receive. Remember that white walls will reflect more light to your plants than dark ones.
South-facing window: Place plants that demand bright, indirect light about 3 to 5 feet away from the window or far enough back that the sun’s rays never quite reach them if your south-facing window receives a lot of sun during the day and is not shaded by surrounding trees or buildings. You can set your plants as close to that window as you like, as long as the sheer drape stays between them and the glass, if that window is shaded or covered with a sheer curtain that diffuses light.
West-facing window: The same general guidelines that apply to unobstructed south-facing windows also apply to unobstructed west-facing windows, especially those that face southwest. It often receives midday sunshine that is hotter and brighter than that coming through an east-facing window. You should therefore situate your plants 3 to 5 feet away from the window panes in these westward-pointing windows as well, or arrange a sheer screen between them and the window.
Unshaded east-facing windows receive direct morning sunshine, but the morning sun’s rays are softer than those of the afternoon sun. Therefore, a diffusing drape is not necessary when placing most plants that like bright, indirect light near or even on the ledge of an east-facing window.
North-facing window: Because north-facing windows rarely get direct sunlight, you may normally put plants that love bright, indirect light on their windowsills, where they will get the most light that is available there. You could want to put a mirror opposite the window to reflect more of the light back at the plants because even that might not be enough illumination for them, especially during the winter. As an alternative, think about getting an LED or fluorescent grow light.
Do I need to mist my anthurium?
A humid atmosphere is ideal for anthurium. As a result, you must water evenly and use lukewarm water for your spray. Depending on the particulars of your case, this will change. You might need to spritz your anthurium every day and water it every few days if you live in a hot, dry climate. You might go a week or two without watering in a humid environment.
The soil squeeze test is the greatest general rule to follow. Insert your finger into the ground up to the first joint. Take a little soil out with your hands. You don’t need to give the plant any more water if you can roll the soil into a ball and squeeze out water or if the ball stays together. Give the dirt some water if you can’t roll it into a ball and it’s powdery.
In terms of fertilizer, you can feed it a mild water-soluble fertilizer every two to three weeks during the growing season. Winter is the wrong time to fertilize. Even if the plant is kept indoors, it will typically require more water in the spring and summer. Depending on the particular climatic circumstances in your area during the fall and winter, you may want to minimize your watering.
Can you keep anthurium in your bedroom?
The anthurium rarely goes dormant in between blooms, making it a perfect choice for the bedroom since you can keep it there all year. “Fun fact: The anthurium’s blossoms are actually modified waxy leaves rather than flowers. This plant will generate more stunning, vivid ‘flowers’ the more bright indirect light it is placed in. Each of these blooms lasts for around eight weeks. The anthurium’s unaltered green, heart-shaped leaves are also rather lovely, in my opinion.”
The ideal window for anthuriums?
Anthuriums are renowned for being picky when it comes to their growing environment. And location is one of the most crucial elements in maintaining their health and beauty. Your Anthurium’s health depends on receiving the proper amount of sunshine, so it’s critical to arrange it in the ideal location in your home. How much light, though, do anthuriums actually require?
Anthuriums require a lot of light to thrive. But take care! A lot of it can burn their leaves. The plant will receive light in the early morning hours but will be protected from the heat of the day if placed in an east-facing window. Keep anthuriums away from windows if they have a southern or western exposure, or use sheer curtains or blinds to block the sun.
[Note: The above advice is based on the premise that you are in the Northern Hemisphere. The directions for northern and southern light exposure must be reversed for any of our readers who live south of the equator.]
Your anthurium could not be receiving enough light if it isn’t blooming frequently or appears to be having a hard time growing. Even while they may be able to live in low light, these plants won’t be at their best. If there isn’t a bright space in your home for your Anthurium, think about shifting it there or adding LED grow lights to make up the difference.
