Causes and treatment methods of non-flowering of Anthurium andraeanum

Anthurium andraeanum because of its fiery red and waxy, with bright yellow stamens, also known as crane flowers and candles, and its meaning is very good, so many families will raise a pot for viewing. But many people will encounter a problem when breeding, that is, Anthurium andraeanum only grow leaves but do not blossom, what is the matter at this time? Let's take a look.

1. Lack of light

The inflorescence of Anthurium andraeanum is formed in the axil of each leaf, which requires that the number of flowers is the same as that of leaves. If the difference is large, it is the light factor. If the light is too little, under the influence of photosynthesis, the plant itself produces less assimilates, fewer leaves and fewer flowers.

Treatment: in the spring, autumn and winter, it can be placed in a place with sufficient light, while the summer temperature is higher and the sun is stronger, so strong direct exposure should be avoided so as not to cause sunburn easily.

2. Insufficient fertilizer

Nitrogen, phosphorus and potassium are the three most important elements for plant growth. In order for a plant to blossom normally, there must be phosphate fertilizer, and the lack of phosphorus will lead to its non-flowering. If nitrogen fertilizer is applied, the mature leaves will grow wildly, and there will be a phenomenon of only long leaves but no flowering.

Treatment method: when we apply fertilizer to Anthurium andraeanum, we try our best to choose the multi-element mixed fertilizer based on phosphorus and potassium element. when we buy fertilizer, there is a table of the content of nitrogen, phosphorus, potassium and trace elements on the package, and the one with the highest element of phosphorus and potassium should be selected. this is the multi-element mixed fertilizer based on phosphorus and potassium. Using this fertilizer to fertilize Anthurium andraeanum can achieve the effect of one leaf and one flower.

3. The soil is too alkaline.

Long-term application of chemical fertilizer or no change of soil for a long time will lead to excessive alkalinity of the soil, which is disadvantageous to plant growth and development, and is also one of the reasons why Anthurium andraeanum does not blossom.

Treatment method: for potted farming friends, pour the flowerpot every spring and autumn season, change the new soil, pour a larger flowerpot, use peat soil, perlite vermiculite according to 3:1:1 configuration. Prune the roots to promote more new roots to avoid excessive alkalinity of the soil.

4. Temperature and humidity are not suitable.

The suitable temperature of Anthurium andraeanum is between 25 and 30 degrees, the highest temperature is 35 degrees, and the lowest temperature is 14 degrees. Once the temperature is too high and too low, it will stop its growth, which is also a reason why it does not blossom.

Treatment method: timely spray moisturizing in summer high temperature season, requiring humidity between 70% and 80%, low temperature and high humidity in spring and autumn, which is easy to induce farmers, and should pay attention to heat preservation and cold prevention.

The above is the reason why Anthurium andraeanum does not bloom and how to deal with it. I hope it can help you. If you want to know more about it, please pay attention to us.
