Spread the love

If you’re like me, the allure of an Anthurium lies in its stunning flower bracts, boasting hues of vibrant red, pink, or white. However, the disappointment of a non-blooming Anthurium can be disheartening.

Fear not! In this comprehensive guide, I’ll unravel the mysteries behind your Anthurium’s reluctance to bloom and provide you with practical tips to transform it into a year-round floral spectacle.

If the requirements of the Anthurium flower are met, it turns out to be a grateful perennial that does not stop blooming. However, the situation is different if the plant does not receive all the care it needs.

It usually produces a lot of foliage, but the beautifully colored leaves with the impressive flower bulbs do not appear. Here we tell you what to do if your anthurium does not bloom.

When does Anthurium bloom?

Anthurium flowering occurs during the spring-summer season. At this time of year, the plant must be helped with a specific fertilizer for flowering. This way it can dazzle with its striking leaves throughout the season. The anthurium flower usually lasts around two months, depending on the care you take of the plant. Once the flowers wither, we must remove them so that new ones can grow during the next flowering.

Reasons why your anthurium is not flowering

If your anthurium is not blooming, here are several reasons that may be affecting its ability to produce those beautiful exotic flowers.

Insufficient Light for Flowers

Illuminate the path to Anthurium blossoms by addressing its light needs. While Anthuriums can endure low light, the absence of vibrant blooms suggests inadequate sunlight. Ensure your plant basks in bright, diffuse light throughout the day, mimicking the filtered brilliance of its natural habitat. If sunlight is scarce, consider incorporating a full-spectrum growth light for a consistent 9-hour daily illumination.

Unsuitable Substrate

The key to unlocking your Anthurium’s full blooming potential lies in its substrate. Inadequate drainage can hinder flowering, as waterlogged soil disrupts oxygen absorption crucial for the plant’s vitality. I recommend a blend of 50% Coconut Fiber and 50% orchid substrate for optimal aeration, ensuring a thriving root system. Remember, proper drainage holes in the pot are non-negotiable.

Temperature Troubles

The thermostat might be affecting your Anthurium’s floral ambitions. Remember, these tropical wonders thrive in temperatures between 70 to 90 degrees Fahrenheit. Guard against drafts and sudden temperature fluctuations by strategic placement away from doors, windows, fans, or air conditioning ducts. Providing a stable and cozy environment is the key to unlocking its blooming potential.

Neglecting Humidity Needs

Humidity plays a pivotal role in your Anthurium’s flowering saga. While it can tolerate 50-40% humidity, a tropical touch of 70-80% is ideal for robust growth and vibrant blooms. Embrace creative solutions like a humidifier, terrarium, or pebble-filled tray under the pot to elevate humidity. Remember, recreating a jungle-like atmosphere is the secret to a flourishing Anthurium.

Nutrient Deficiency

Nutrients are the lifeblood of your Anthurium’s flowering prowess. Container life deprives it of the natural soil processes, making supplemental nourishment crucial. Opt for a phosphorus-rich liquid fertilizer, diluted to 10-20% strength, applied after watering or directly on the foliage. This nutritional boost mimics nature, providing the essential elements for a blooming spectacle.

How to make Anthurium bloom

Here are a few simple adjustments you can make in the care of your plant, to enjoy its beautiful flowers all year round.

Give enough light

The most influential factor in the flowering of anthuriums is light. You want to place them somewhere bright all day but still out of direct sunlight which can damage them. While you may not notice anything negative about your plants’ growth in low light, bright, indirect light encourages flowering.

You can use a grow light in the greenhouse to compensate for this requirement and turn it on for 9 hours a day. A full spectrum grow light will be the best option for creating healthy and vibrant anthurium flowers. Otherwise, place the plants in a location that diffuses light throughout the day.

Provide good temperature and humidity

The next factors you can manipulate in the greenhouse to make anthurium bloom are temperature and humidity. Be sure to place the anthuriums away from drafts or other elements that can cause rapid temperature changes.

Be aware of vents, vents, and exhaust fans that can cause this. As for the humidity requirements of anthuriums, they would do well at high levels. You can also increase the environmental humidity by spraying or misting the plant from time to time.

Water and feed correctly

Once you have a stable ideal environment for anthuriums, the next step is to check your practices. This includes knowing how to water and feed them, as these actions can also affect the flowering of anthuriums. In general, you want to maintain the moisture of the medium and give the plants a nutritional boost from time to time.

Feed them properly

Gardeners recommend feeding anthuriums with a fertilizer for flowering plants. You want to mimic the natural process of nutrient uptake in nature from forest debris and natural soil processes. You can do this by diluting the fertilizer and spraying it onto the foliage or soil after watering.

Those growing anthuriums in pots can also feed with high-phosphorus liquid fertilizer once a week. Personally, I favor granular fertilizers for their convenience, requiring application only every two months.

If your Anthurium seems reluctant to bloom, don’t be disheartened. By ensuring it receives abundant indirect sunlight, proper watering, elevated humidity, and a periodic phosphorus-rich fertilizer regimen, you’re laying the groundwork for a blossoming masterpiece.

Does anthurium bloom all year?

The anthurium can flower all year round, but usually, its flowering lasts about three months. After this period it begins a new cycle. In winter, the plant generally produces a few fewer flowers, but when the sun comes out more often, the anthurium comes out of its hibernation phase and starts again.

The secret to coaxing anthuriums into a second flowering is maintaining a cozy environment at around 60°F, creating the perfect setting for the upcoming flower spectacle.

However, if a flower exhibits any signs of discoloration, grant it the freedom to dry up and gracefully depart. Remarkably, some anthuriums might surprise you with green blooms, a telltale sign of their resilience and ability to bloom even during their dormant phase. It’s nature’s way of orchestrating a unique encore performance.

In conclusion, your Anthurium’s blooming journey is a reflection of its environment and care. Follow these tips diligently, and soon you’ll be reveling in the breathtaking beauty of your Anthurium’s vibrant flowers. Happy blooming!
