What to Do When Anthurium Won't Bloom? Causes and Solutions Explained
Because the anthurium's flower is fiery red and waxy, paired with a pale yellow spadix, it is also called the flamingo flower and painter's palette, and its symbolic meaning is excellent, so many households keep a pot for ornamental purposes. But many people run into a problem when growing it: the anthurium only grows leaves and won't bloom. What is going on here? Let's take a look.
1. Insufficient light
The anthurium's inflorescence forms in the axil of each leaf, which requires the number of flowers and leaves to be equal. If the difference is large, then it is a light factor. If there is too little light, under the influence of photosynthesis the plant itself produces relatively fewer assimilates, there are fewer leaves, and therefore fewer flowers.
Solution: In spring, autumn and winter it can be placed in a spot with ample light, while in summer the temperature is higher and the sunlight is stronger, so strong direct light should be avoided to prevent sunscald from prolonged exposure.
2. Insufficient fertilizer
Nitrogen, phosphorus and potassium are the three most important elements needed for plant growth. For a plant to bloom normally, phosphorus fertilizer is essential; a lack of phosphorus will cause it not to bloom. If nitrogen fertilizer is applied in excess, the leaves will grow rampantly, producing the phenomenon of only leaves and no flowers.
Solution: When fertilizing the anthurium, try to choose a multi-element compound fertilizer based mainly on phosphorus and potassium. When buying fertilizer, the packaging has a table of nitrogen, phosphorus, potassium and trace element content; choose the one with the highest phosphorus and potassium content, which is a multi-element compound fertilizer based mainly on phosphorus and potassium. Using this fertilizer on the anthurium can achieve the effect of one flower per leaf.
3. Soil too alkaline
Long-term application of chemical fertilizers to the potting soil, or not repotting and changing the soil for a long time, can make the soil too alkaline, which is unfavorable to plant growth and development and is also one of the causes of the anthurium not blooming.
Solution: For those growing it in pots, it is advisable to tip out the pot every spring and autumn, change the soil, and move it into a pot one size larger, using peat soil, perlite and vermiculite mixed at 3:1:1. Trim the roots a little to encourage more new roots and avoid the soil becoming too alkaline.
4. Unsuitable temperature and humidity
The suitable temperature for the anthurium is between 25-30 degrees; it can tolerate a maximum high temperature of 35 degrees and a minimum low temperature of 14 degrees. Once the temperature is too high or too low, its growth will stop, which is also one of the reasons it does not bloom.
Solution: In the hot summer season, spray in time to maintain moisture, requiring humidity between 70%-80%. In spring and autumn the temperature is lower and the humidity is higher, which easily induces growers, so pay attention to keeping it warm and protecting it from the cold.
