What to Do If Anthurium Does Not Bloom? Causes and Solutions
The anthurium has a graceful posture, with leaves growing on the upper slant of the petiole, and petals fiery red and exceptionally vivid, but during cultivation it often fails to bloom. The main reason is that care and management are not carried out according to its ecological habits; for example, an anthurium with insufficient light will not bloom. Below, let us take a look at what to do if an anthurium does not bloom!
When Does the Anthurium Bloom
The anthurium has a very long flowering period. Generally, after the anthurium blooms, each flower's flowering period lasts about one month, and what is most unusual is that the anthurium can bloom all year round. The flowers are unique, with a spathe inflorescence, and the colors are vivid and gorgeous and richly varied. Each flower's flowering period lasts about one month, and what is most unusual is that the anthurium can bloom all year round. The flower color also changes greatly; from the unfolding of the bract to the withering and fading of the flower, the color undergoes a series of changes, from the initial cream yellow to milky white, finally becoming green, and turning yellow again before withering. The bracts are leaf-shaped; common bract colors include red, pink, white, and so on.
What to Do If the Anthurium Does Not Bloom
The main reasons an anthurium does not bloom are that the placement location is too dark and there is too much nitrogen fertilizer. The anthurium likes warmth and fears cold, likes moisture and fears drought, likes shade and avoids sun exposure, and growth is also inhibited when the temperature exceeds 30 degrees. In winter, the minimum room temperature should be above 10 degrees, otherwise the anthurium is prone to frost damage. For the growing soil, use mountain forest leaf mold with good air permeability and high humus content, mixed with a small amount of coarse sand and sheep manure. Because the fleshy roots of the anthurium contain a lot of water, when planting, spread several layers of relatively large pieces of rot-resistant bark or large-grained stones flat at the bottom of the pot as a drainage layer.
The Growing Environment of the Anthurium
1. Temperature: The anthurium is relatively sensitive to temperature. The suitable growth temperature is 14-35°C, the optimal temperature is 19-25°C, and the day-night temperature difference is 3-6°C, that is, it is best to be 21-25°C during the day. If it is below about 13°C for a long time, although the plant will not die, it will be difficult to recover growth for a long time. When the temperature is higher than 35°C and the light is relatively sufficient, leaf surfaces are prone to sunburn. Because damaged leaves will not reverse, this affects the overall quality of the anthurium.
2. Light: The anthurium is a shade-tolerant plant and avoids direct sunlight, but do not think that because the anthurium is a shade-tolerant flower it does not need light. According to observations, when light increases by 1%, its flower production also increases by 1%, except that this is within the suitable light intensity range for the anthurium. The relatively suitable light intensity range is 10000-20000 lux, mainly determined according to different varieties and different growth conditions at different growth stages. Under any circumstances, ensure that light does not exceed 25000-30000 lux for a long time.
3. Humidity: The optimal relative air humidity for the anthurium is 70%-80%, and it should not be lower than 50%, because maintaining relatively high air humidity in the cultivation environment is the key to successful anthurium cultivation.
4. Soil and Fertilizer: For potted anthurium soil, it is advisable to use peat soil plus 1/4 perlite, and additionally mix in a small amount of bone meal or decomposed cake fertilizer powder and mix evenly. The bottom of the pot needs a layer of coarse sand and other materials to facilitate drainage. After a period of cultivation and management, the substrate of the anthurium will undergo biodegradation and salinization, thereby lowering the substrate pH value and increasing the EC value, thus affecting the root system's ability to absorb fertilizer and water. Therefore, the pH value and EC value of the substrate must be measured regularly, and the proportion of each nutrient element adjusted according to the measured data, so as to promote the plant's absorption of fertilizer and water.
