How to Grow Anthurium andraeanum Hydroponically at Home and Solutions for It Not Blooming

Anthurium andraeanum - when people hear this name, they are rather unfamiliar with its morphological features, as if they have never seen it, but it is actually very beautiful. Its planting methods are generally divided into two types: soil culture and hydroponics. Today we will introduce its hydroponic method and see how it is grown.

How to Grow Anthurium andraeanum Hydroponically at Home

1. Dig the potted Anthurium andraeanum out of the soil, cut off rotten roots, fibrous roots and old leaves, wash it clean with water, put it into potassium permanganate solution for disinfection, and then rinse the Anthurium andraeanum again with water. If you use a transparent glass container for hydroponic Anthurium andraeanum, it is best to wrap a black plastic bag around the outside of the glass to prevent strong light. Cover the top with a transparent convenience bag (for heat and moisture retention). Place it in a spot with scattered light, and keep the temperature above 10 degrees.

2. During the acclimation period of hydroponic Anthurium andraeanum, change the water frequently. In the first half month, change it once every 3 days; in the second half month, once a week. Each time you change the water, add nutrient solution once, and the nutrient solution should be specially selected for hydroponic flowers. After one month, Anthurium andraeanum will grow new roots, and the newly grown roots will be relatively adapted to the aquatic environment. The leaves will begin to sprout new buds.

3. Potting hydroponic Anthurium andraeanum. If a semi-transparent pot is used for hydroponic Anthurium andraeanum, it will be a bit easier. Carefully put the Anthurium andraeanum roots into the hydroponic basket; river stones or ceramsite can be put into the basket to fix the position of the plant. Add water to half or 2/3, so that the roots not submerged in water can still breathe from the air.

4. For acclimated hydroponic Anthurium andraeanum, water can be changed according to actual conditions. When there are many impurities in the water, it should be changed. After a period of time, the hydroponic pot should also be cleaned. Nutrient solution should not be added too frequently, because it will cause eutrophication of the water, accelerate the reproduction of microorganisms in the water, and the oxygen content of the water will drop sharply, which is not conducive to growth.

5. If a larger pot is used for hydroponic Anthurium andraeanum, small fish can also be kept in the water. Plants and fish mutually benefit each other and also form a corresponding landscape.

What to Do If Anthurium andraeanum Does Not Bloom

1. Suitable light

Light conditions are an important factor affecting the blooming of Anthurium andraeanum. Too strong light will lead to poor blooming of Anthurium andraeanum. Especially in summer, the scorching sunlight together with high temperature will damage the plant and its branches and leaves, thus causing the phenomenon of not blooming. So when cultivating Anthurium andraeanum, it is best to place it in an environment with scattered light to avoid direct sunlight on the plant.

2. Higher humidity

Anthurium andraeanum likes high humidity. The climate and environment in the south are relatively humid, but due to regional differences, the condition of high humidity cannot be reached in the north. The climate and environment in the north are very dry, and the humidity is insufficient, which will have a great impact on the blooming of Anthurium andraeanum. In addition, when the editor says here that Anthurium andraeanum likes high humidity, it does not mean giving Anthurium andraeanum more water. Do not misunderstand. Too much watering will instead have the opposite effect. So when watering Anthurium andraeanum, it is best to supplement moisture in the form of spraying. If the leaves are dry and cracked, the leaf surface should be moistened even more.

When spraying water, try to spray around the plant, which can increase the air humidity around the plant, and try not to spray it onto the leaves. In addition, if you want Anthurium andraeanum to produce perfect flowers, there are two more points we need to pay attention to. The most suitable growth temperature for Anthurium andraeanum is between 20 degrees and 30 degrees. Ensuring a suitable growth temperature for Anthurium andraeanum is very important. Also, the humidity should be suitable, which is beneficial to the blooming of Anthurium andraeanum. The second is that reasonable fertilization can be carried out. You can buy some nutrient fertilizers on the market that promote the blooming of Anthurium andraeanum.

Precautions for Cultivating Anthurium andraeanum

1. Choose according to the size of the plant. It cannot be too large, otherwise the soil will dry very slowly after receiving water, affecting the root system.

2. Repot in a timely manner so as not to affect the normal growth of the plant. Be careful when repotting, and do not damage the root system.

3. Absolutely avoid water accumulation. Just keep the soil moist. Do not water on winter nights, otherwise the rhizome is likely to be frostbitten.

How to Fertilize Anthurium andraeanum

1. Soil and fertilization

Anthurium andraeanum is relatively fond of fertilizer. For potted Anthurium andraeanum, the soil should preferably be fertile, loose, and have good air permeability and water permeability. It would be even better if the soil could also contain part of the nutrients necessary for the growth of Anthurium andraeanum. Soil containing leaf mold under trees is a very good choice. In addition, before putting soil into the pot, laying a layer of broken brick and tile pieces at the bottom of the pot can effectively improve drainage.

2. Temperature and fertilization

When the temperature drops to a certain level, the plant will stop part of its physiological activities, and at this time fertilization is not allowed. The optimal growth temperature range for Anthurium andraeanum is between 19 degrees Celsius and 25 degrees Celsius. So, for example, in northern China, in summer it is necessary to prevent the surrounding temperature from being too high, and in winter it is necessary to prevent unnecessary frostbite, and stop fertilization when necessary.

3. Water and fertilizer management

Anthurium andraeanum is especially afraid of dryness, so it is best to water it once every two days. However, do not water too much at one time when watering. Water accumulation in the pot may cause the roots of Anthurium andraeanum to rot. When watering, add an appropriate amount of one to two drops of liquid fertilizer, which can better promote plant growth.

It turns out that when cultivating Anthurium andraeanum, the requirements for water are very high, and special care must be taken when repotting, so these two points should be paid special attention to during cultivation. And if you want to see the most beautiful Anthurium andraeanum in bloom, it is generally recommended to plant it in April-May, because the peak blooming period of Anthurium andraeanum is in May-June.
