Will Anthurium Rebloom? Let’s find out!

Sharing is caring!

Anthurium, also well-known as tailflower, flamingo flower, and laceleaf, belongs to a genus of 1,000 species of flowering plants.

Anthurium produces beautiful blooms that come in varying shades of white, yellow, pink, orange, or green.

But the blooms most commonly grown are mainly red in color.

Looks can be deceiving. Although Anthurium blooms look exotic, they are toxic.

The blooms on an Anthurium plant are one of the longest blooming indoor flowers that live up to 2 to 3 months.

Will Anthurium Rebloom?

When taken care of properly, an Anthurium can rebloom all year around. If the condition in which your Anthurium is grown mimics those of a tropical rainforest, you can expect up to 6 blooms per year, each lasting 8 weeks long. The best conditions to make your Anthurium rebloom are temperatures between 70-85 °F (21-29 °C), bright indirect sunlight, and high humidity.

 

Why Won’t My Anthurium Rebloom and How to Make it Rebloom?

 

Potting Mixture

New plant owners always assume it’s good to water your plant frequently. However, this is not applicable for Anthuriums. Anthurium requires a well-draining potting mixture.

Waterlogging in the soil can prevent the roots from taking up oxygen and can lead to root rot.

Ensure your potting mixture has a pH close to 6.7 or 5.5 (slightly acidic) and has a coarse texture.

 

Lighting

Anthuriums can bloom sufficiently in lower light conditions. However, bright indirect light is best and a lack of light might prevent reblooming.

Avoid placing your Anthuriums in direct sunlight as they can burn the leaves. Adequately lighting for 9 hours a day is mandatory to ensure beautiful blooms.

Use a grow light to regulate and supplement the light exposure to your Anthurium.

 

Temperature

Anthurium blooms thrive well in most indoor settings. However, they are sensitive to rapidly changing temperatures.

To ensure your Anthurium doesn’t suffer from temperature changes, keep them away from doors, windows, heating, and cooling systems.

 

Humidity

Since Anthuriums are tropical plants, they require a high humid environment to survive. Lack of humidity will take away the sheen from your foliage and hinder its ability to produce blooms.

To provide adequate humidity, keep your plants closer together or purchase a humidifier. However, you need to ensure that there’s proper ventilation.

Too little airflow can lead to insects, mold, or fungus infesting, while too much airflow can cause your Anthurium foliage to dry and scorch.

To control the ventilation, use a gently blowing fan.

 

Repotting

As time passes, the potting mixture will breakdown and become compact, depriving your Anthurium of much-needed oxygen.

If you frequently fertilize your potting mix, you will also have a problem with leached salts.

Hence, you should repot your Anthurium every two years.

When deciding to repot your Anthurium, ensure that the new pot is the same size or at most 2 inches larger than the previous pot.

When repotting, fill only 1/3 of the pot with the potting mixture.

As new air roots grow, gradually add more potting mix.

 

Watering Issues

Improper watering is one of the common reasons why your Anthurium won’t rebloom. Anthuriums love moisture, but excessive watering can, as previously mentioned, lead to root rot.

When watering your Anthurium, ensure there are proper drainage holes to prevent waterlogging.

Water the soil mixture once again if the soil is dry to touch.

You will need to water your Anthurium more frequently during hot temperatures, almost every day, and less often during cooler seasons, 2-3 times per week.

 

Diseases

Anthuriums are highly susceptible to bacterial and fungal diseases, which can prevent reblooming.

Conditions such as bacterial blight, bacterial wilt can manifest due to waterlogging and cooler temperatures, respectively.

On the other hand, fungal infestations such as root rot, water molds, and black nose disease are also common. Water mold and root rots occur as a result of over-watering and improper drainage.

Black nose disease results from serve humidity and warm conditions.

Using fungicides containing mefenoxam and mancozeb are useful in combating water molds and black nose diseases.

To avoid damage to your Anthurium from bacterial wilt, you need to properly sanitize your shearing tools with quaternary ammonium compounds.

 

Others

Other than providing adequate growing conditions for your Anthurium, you can prune wilted or wilting blooms.

Pruning wilting flowers will allow your Anthurium to provide nutrients to new blooms rather than keeping dying blooms alive.

Cut the stalk with the wilting bloom as well as remove dead and decaying foliage. If you notice browning leaves, gently remove the leaf using a sterilized shearing tool.

Use phosphorus-rich liquid fertilizer per month to provide your Anthurium the nutrient it requires to produce beautiful blooms.

When purchasing an NPK fertilizer, note the center value (P) to ensure high phosphorous content; 20% phosphorus content is ideal.

Don’t overly fertilize your Anthurium as salt can build up in the soil, burning the roots. Avoid using fertilizing during the fall and winter seasons.

 

Frequently Asked Questions about Anthurium and Reblooming

 

Will Anthurium produce blooms in winter?
