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.
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.
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.
How much sun is required by an anthurium?
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.
Can anthurium endure dim lighting?
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.
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.

My potted anthurium may I place outside?
In ideal circumstances, an anthurium can be placed outside. Being a tropical plant, it prefers warm weather. The Anthurium can be left outside during the summer if the temperature is around 20C. However, be sure to set it where there is no draft, no direct sunshine, and no temperature below 16°C. It is therefore preferable to bring your plant back inside when it becomes chilly at night.
How frequently do I need to water my anthurium?
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.
Indirect sunlight: What is it?
The two types of light—direct sunlight and indirect sunlight—are the first topic we’ll cover in our indoor plant light guide. Both of these types of light are probably present in your home; the trick is to arrange your houseplants to take advantage of each type of light.
Direct Sunlight
Direct sunlight is defined as light that travels in a direct line from the sun to the plant. For instance, the majority of window sills receive direct sunshine. If your house doesn’t receive enough direct sunshine to feed your plant collection, you can also create direct light with LED grow lights.
Indirect Sunlight
When something blocks the sun’s path and diffuses or filters the light before it reaches your plants, this is known as indirect sunlight. Sheer curtains, furniture, a tree outside your window, or even a different indoor plant placed in front to shield the lower-light plant are some examples.
How are anthurium blooms kept vibrant red?
However, if your plant’s blossoms start off green and stay that way, it’s definitely not getting enough light.
Balancing the lighting for these plants may be a real challenge. When novice plant owners realize that anthuriums like indirect light, they often treat them as shade plants.
The Flamingo Flower, however, is accustomed to receiving sun all day long because it evolved in the tropics. It simply prefers filtered or reflected light to direct light that beams directly onto its leaves.
Keep your Anthurium in a room with lots of natural light for the most vibrant blooms.
Simply avoid placing it right next to a window.
Another concern if you’re using fertilizer is that your plant can be receiving too much nitrogen. Anthuriums prefer a diet high in phosphorus, and too much nitrogen can also alter their color.
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.
My anthurium is dying; why?
The good news is that this plant probably only loses its flowers as a normal part of its life cycle! You may only be in-between blooms because a well-cared-for anthurium blooms at intervals of about three months all year long. If not properly cared for, this tropical plant may also be temperamental, so you may need to make some adjustments if your plant’s blossoms and leaves are fading or wilting.
Sharp shears should be used to remove any wilting or browning flowers to encourage healthy growth so that the plant may focus its efforts on maintaining its healthy blossoms. Here are some typical causes of anthurium blossom loss and tips for assisting your plant in recovering if its health is continuing to decline.
Overwatering or Underwatering Your Anthurium
Anthuriums can lose their blossoms due to both too much and too little water, but too much water might kill your plant completely by causing root rot. You need to make some quick course corrections in your routine for caring for plants if you notice that their leaves are browning or drooping along with the loss of blossoms.
During the growing season, which runs from March through September, keep the soil just barely damp. After giving your Anthurium a good soak, wait until the top couple of inches of soil are totally dry before giving it another drink.
Cold Damage to Your Anthurium
Tropical flowering plants called anthurium need warm temperatures to thrive. While indoor plants are typically kept warm enough, overly aggressive air conditioners or the winter can cause cold damage. Your anthurium enjoys daytime temperatures of 65 to 80 degrees and nighttime lows of no lower than 60 degrees. Your plant will benefit from air circulation, but keep it away from fans and vents for your air conditioner and heater.
Improper Light Conditions For Your Anthurium
The more light the plant receives, the more flowers it will produce; however, never expose the plant to direct sunlight as this will cause it to quickly stop producing flowers as well as die. Your Anthurium should be placed in an area with strong indirect light. They can handle less light in the winter.
Improper Humidity For Your Anthurium
Your Anthurium will benefit from daily spraying because it enjoys a humid environment. Use a humidifier or a pebble tray in the winter when the air is more likely to be dry.
Is it okay to place anthurium on a window?
A north or east-facing window will offer gentler, indirect light for indoor care that won’t burn the leaves of your anthuriums. If you don’t have a sheer curtain to diffuse the light, windows that face the west and south can be a little too bright. Alternatively, you can arrange your anthuriums far from any direct light sources, such as a bright window.
Although Florida’s humidity is ideal for growing anthuriums outdoors, the air inside of our houses is frequently much drier. You might need to add more humidity if the flower and foliage tips start to get crispy and brown. If we want plants to continue removing harmful poisons from the air, their leaves must remain supple and moisturized!
Using a spray bottle to mist your plants will keep them looking healthy, supple, and well-groomed. You may also keep them on a pebble tray that has an inch of water in it; this will allow water vapor to reach the leaves directly. Once a week giving their leaves a wipe-down allows them to absorb more sunlight and gives them a lustrous appearance. Keep them away from any chilly air conditioning breezes since it makes them anxious!
