How to Care for Anthurium Plant

Looking for a flowering houseplant? Look no further than the tropical anthurium. Anthurium plants, also known as “Flaming Flower”, are one of the most beautiful and low-maintenance houseplants you can grow.

Luckily for us, they’re both pleasing to look and easy to care for.

Indoor plants are known for their low-maintenance qualities and their lush green foliage, but few house plants produce the stunning heart-shaped flowers that anthuriums do.

These flowers are not technically flowers – they’re spathes, or modified leaves, that grow out of the plant’s spiky spadix. This makes them incredibly long-lasting so you get the best of both worlds: glossy, deep-green leaves and sturdy, flowering blooms.

Anthuriums are not only stunning, though, they also help purify the air in your house, just as many other popular houseplants do, including the pothos plant.

Warning: Anthuriums are toxic to pets if ingested, so make sure to keep them away from your fur babies! Also, remember to use gloves when removing leaves because the plant’s sap can cause minor skin irritations. Keep plant out of reach of children, too.

Anthuriums Need Indirect Sunlight and Humidity

Unlike many low-light houseplants, anthuriums need plenty of sunlight to produce the flowers they’re famous for. They’re one of the world’s most longest-blooming plants, so depriving it of the sunlight it needs will severely hinder its bloom production.

However, giving this plant access to strong, direct sunlight for hours on end is not the way to go. Doing this can actually cause your plant distress and can also lead to sunburnt leaves.

Instead, aim to place your plant in an area of your house that receives filtered light throughout the day, such as on a table near a window. 

Anthuriums also need humidity, since they’re native to tropical environments. They do best in room temperatures above 60 degrees Fahrenheit and about 80 percent humidity.

This is why they make such good houseplants! Keeping them outdoors in temperature below 55 degrees is not ideal for this plant.

If you’re unsure about the humidity levels in your home, try placing your anthurium near your kitchen or a bathroom. You can also try using a humidifier to increase the humidity in your house.

Repotting Root Bound Anthuriums

Anthuriums do well in smaller containers, but they eventually outgrow them. To encourage growth, you should aim to repot your plant every couple of years.

You want to increase the pot size gradually, however. Never repot your houseplant in a container that is far larger than the one that it came in because this can shock the plant.

Instead, find a container that’s about 20% larger than the plant’s current container. Repotting this way will minimize shock and also the anthurium with enough space to grow.

How will you know when it’s time to repot your anthurium plant? To determine whether it’s time to repot, simply take a look at the plant’s root system.

To do this, gently tilt the pot sideways and then lift up your anthurium by the base so that the roots are exposed.

If the sides and bottom of the soil are covered with roots, then it’s time to repot. Also, tangled roots that are growing out of the drainage hole is a sure-fire sign that it’s time to repot.

Take a look at the photo below: this anthurium’s root system is beginning to look pretty root bound. It’s not too bad, but it’s a good idea to repot at this time before the situation gets out of hand.

How to Water an Anthurium Plant

The surest way to kill this indoor plant is to over water it! It’s why learning how to properly water anthuriums is so important.

Always remember that this tropical plant does not like to be overwatered and does not like to sit in soggy soil, much like pothos plants and succulents.

Only water your anthurium house plant when the soil is dry. To test the dryness of the soil, simply stick your finger into the soil about an inch deep. If the soil feels dry, it’s time to water.

Grab your watering can and soak the soil until you see water escape from the drainage hole (you should never plant houseplants in pots that don’t contain a drainage hole).

Once you see water drip out of the container, it’s time to stop watering! Discard any remaining water from the saucer, and let your plant soak up the water it needs. Let the soil run dry again until your next watering.

You’ll usually need to water your anthurium about once a week during the cooler months, and every few days during Summer months.

Remember that anthuriums can tolerate dry soil, so wait to water until an inch of the soil lacks moisture.

Observing the Leaves of Your Anthurium

The leaves of your beautiful anthurium plant will give you signs as to whether or not they’re getting the light and water they need.

If you pay close attention to your plant, you’ll be able to diagnose any problems it might be experiencing.

For example, if the leaves are turning yellow, your plant is likely getting too much sunlight and should be moved farther away from the light source.

If the tips of the leaves start to brown, you might be giving your plant too much or too little water.

If the soil feels dry, give your plant a good watering and if the soil feels moist, give it a few days before your water again.

Also, if the flowers are not gaining color, this means the plant isn’t getting enough sunlight. Most anthurium blooms are red, pink, white, or yellow, so if the blooms are the same color as the foliage, then that’s your sign to move it closer towards the sunlight.

Remember that anthuriums need enough light to produce their flowers, so make sure you place your plant in a spot that gets several hours of indirect sunlight each day.

Deadheading Anthuriums

Anthurium blooms are famously long-blooming. The blooms last about three months before dying off and taking a good rest.

When your plant’s blooms are spent, grab your pruning shears or sharp scissors and snip them off. Your plant will produce more blooms in a few months.

Always protect your hands when you trim your anthurium because the plant can cause minor skin irritation.

Fertilizing Anthuriums Plants

The appropriate fertilizer can strengthen your plant and aid in bloom production. You can fertilize your plant in the Springtime, which is when the plant usually begins to wake up from its rest.

Always choose a fertilizer that is high in phosphorus and low in nitrogen; phosphorus will encourage blooms whereas nitrogen can strangle them.

Anthurium care is not complicated or time-consuming. If you can remember to water your anthurium when the soil is dry and place it in a spot that gets plenty of indirect sunlight, then you should be able to enjoy anthurium plants in your home.

Anthuriums are tropical plants, so they thrive indoors and in humid environments. If you’re a gardening beginner who is looking to test the waters, then anthurium plants are for you!
