How to Grow Anthurium Plants at Home:
4 Things to Do Before Planting an Anthurium
- Choose a Container. Find a well-draining container that isn’t much bigger than your plant’s rootball.
- Gather Supplies. You’ll need a suitable potting mix, a plant dish, and sturdy gardening gloves.
- Choose a Home. Anthuriums are easy to grow, but moving them around frequently can put stress on the plant. Look for a spot with the right sunlight and temperature.
- Prepare to Pot. If it’s cold outside, stay indoors to plant your anthurium. Find a sturdy surface and cover it with old newsprint for easy cleanup.
Anthuriums grow moderately slowly. With perfect conditions, they’ll grow more quickly. Mature plants reach about 12 to 18 inches in height with a spread of about 9 to 12 inches.
How to Plant an Anthurium
- Prepare a soil mixture using the guidelines listed below.
- Choose a well-draining container that’s only slightly larger than the plant’s rootball.
- Fill the container 1/3 of the way full with your potting mixture and place the anthurium on top.
- Continue adding potting mixture around the sides until the soil covers the roots.
- Gently pat the soil.
- Water until thoroughly wet. Allow moisture to drain completely.
How to Grow an Anthurium in Water
This attractive anthurium growing method uses principles of hydroponics. You’ll need a vase, mineral water, and indoor houseplant fertilizer.
First, rinse the anthurium’s roots until they’re completely free of soil. This will help prevent the bacterial and fungal growth that leads to root rot. Place the anthurium in a vase and fill with water until the waterline is just below the plant’s stems. Replace water at least once a month or more frequently to prevent rot and replenish the anthurium’s mineral source.
The Best Anthurium Plant Soil Mix
When creating an anthurium potting mix, consider where they grow naturally. Big surprise – wild anthuriums don’t grow in pots. They don’t even grow in the ground. Anthuriums actually grow from the bark of trees in tropical rain forests.
The best way to mimic an anthurium’s natural environment is by using a porous, coarse, low-moisture potting mix that will drain completely.
Make your own anthurium potting mix by combining:
- (approx) 1 part pine or fir bark
- 1 part peat moss
- 1 part pearlite
To purchase a potting mix, combine:
- 5 parts low-moisture potting soil
- 2 parts orchid potting mix
- 2 parts peat moss
- 1 part pearlite

Anthurium Light Preferences:
Anthuriums thrive in sunlight filtered through leafy canopies. They prefer moderate, filtered, or indirect light to grow properly. Their leaves can scorch if placed in a window that receives direct sunlight.
For more, see our in-depth guide to Anthurium plant light requirements.
Optimal Temperature and Humidity:
Anthuriums thrive in the temperature range we find comfortable, too! During the growing season (spring and summer), they like it a little warmer, and they prefer it slightly cooler during the dormant season (fall and winter).
They prefer a humid environment. Treat yours with an occasional misting or by running a humidifier nearby. Avoid placing an anthurium near an air conditioning vent, drafty window, or exterior door. A frequent burst of cool, dry air can stress your plant, stunting its growth and preventing it from blooming.

Anthurium Plant Care at Home:
When to Water Anthurium Plants:
Anthuriums are sensitive to root rot. Although they like humidity and frequent watering, they won’t tolerate standing water or overly saturated soil. Let the soil dry almost completely between waterings.
During warmer months, water your anthurium once a week. In the winter, water once every two to four weeks. Depending on your climate, you might need to water your anthurium more or less often.
When watering, take your anthurium to the sink. Soak it until the water runs out of the bottom of the plant. Let it drain completely before returning it to its favorite spot.
Watering with mineral, filtered, or distilled water is fine. If you’re on a city water system, use filtered water because chemicals like fluoride and chlorine can irritate the plant.
When to Fertilize Anthurium Plants:
During the growing season, fertilize anthuriums once a month with a balanced 1/4-strength plant fertilizer that’s high in phosphorous. Too much fertilizer can harm your plant. So, less is more.
When to Prune Anthurium Plants:
Anthuriums don’t require much pruning. Use clean, sharp pruning shears to remove spent blooms and yellowed leaves. Trim stems near the base of the plant.
Splitting the plant is the simplest way to propagate an anthurium. This requires neither a degree in botany nor any special supplies.
When new growth begins to sprout in the spring or summer, remove the plant from its pot and divide it into two (or more) sections with at least three leaves each. Avoid breaking roots and stems in the process. Pot the separate sections following the anthurium potting instructions above.
When and How to Repot an Anthurium:
It’s best to repot anthuriums during the growing season. However, if an anthurium is rootbound, re-pot it immediately. When anthuriums are rootbound, you might notice roots growing above the soil, roots sprouting from the drainage hole, wilting leaves, or a cracked/bent container.
- Water the anthurium a couple hours before repotting to moisten the roots for an easier transplant.
- Select a container that’s one to two inches larger than your current pot.
- Prepare a similar potting mix.
- Gently slide the anthurium out of its current pot and tease its roots loose.
- Fill the new container 1/3 full, place the anthurium inside, and fill in with potting mixture until it reaches the same level as in the previous pot.
- Water lightly to allow the soil to settle.
- Top off with additional potting mixture.
Beware, it’s normal for your anthurium plant to appear droopy for a couple of days after repotting.
5 Common Anthurium Problems & How to Treat Them
1. Roots Growing from Stems
Roots growing from the stems above the soil are aerial roots. They’ll benefit from an occasional misting or, if you don’t like their looks, simply trim them.
2. Roots Above Soil
Roots sprouting from the soil or through the pot’s drainage hole indicate a rootbound plant. Repot as soon as possible.
3. Yellowing Leaves
Yellowing leaves indicate several problems. Your plant might be receiving too much sunlight, too much or too little water, or it could be rootbound. Inspect your plant’s environment and care to determine the proper adjustment.
4. No Blooms
In ideal conditions, anthuriums bloom year-round. If yours lacks blooms, this could indicate a problem with its environment or care. Try giving your plant a bit of fertilizer and moving it to a sunnier location.
Anthuriums are susceptible to mealybugs, scale, and aphids. If you see pests, take action right away. Wash your plant’s leaves with a mild soap (avoid splashing it on the roots) or apply a pest-specific treatment from your local garden center.
