How to Grow Anthurium? A Detailed Guide to Hydroponic Anthurium Cultivation
What should you pay attention to when caring for anthurium flowers at home?
1 Hydroponic anthurium The suitable humidity for anthurium
Anthurium likes a relatively humid environment. The humidity mentioned here refers to the relative humidity in the air, not just the water content in the growing medium. And humidity is a variable, because when humidity rises and dry winds intensify (especially in northern China), if water is not replenished, the humidity will drop. Generally speaking, the humidity anthurium needs should be kept at 70%—80% (temperature 20—28°C). The level of humidity can regulate moisture for anthurium, that is, it regulates the transpiration from the leaf surface of anthurium.
2 The suitable humidity for anthurium
If the relative humidity is too low, it causes drought and water shortage, the edges of the leaves and spathes become dry and withered, and the spathes become uneven. The water temperature for watering anthurium should be kept at around 15°C (including the nutrient solution used for watering); this point is especially important in severe cold and extreme heat. And the medium moisture should not be too wet, because the roots of anthurium are semi-succulent, and the roots themselves store a large amount of water. Too much water in the medium causes a lack of oxygen in the medium, obstructs root respiration, and being in an overly wet state for a long time will cause root rot. You can use discarded cola bottles or mineral water bottles, fill them with tap water, let it sit for 3—4 days, then pour it into a spray bottle and spray the leaf surface of the anthurium. In summer, spray once at 10:00—11:00, and spray once after 15:00, but the pH value of the sprayed water should be low.
3 How to manage anthurium
After adding the nutrient solution, it should also be left to sit as described above before use. On one hand, the chlorine in tap water can volatilize; on the other hand, water that has been left to sit can stay consistent with room temperature. Do not put the water that has been left to sit in the sun, to avoid the growth of green algae. If you use cooled boiled water, that is also feasible. When growing anthurium hydroponically, the speed of inducing new roots takes a relatively long time compared with plants such as Aglaonema. However, its root system is quite vigorous; once hydroponic roots form, it is extremely easy to care for. Therefore, you should choose robust, virus-free anthurium plants. They can be disinfected with agricultural streptomycin, and then acclimated with a flower nutrient solution.
For hydroponics, pay attention to water quality. It is best to use mineral water. Tap water needs to be left for a few days before it can be added!

Cultivation Techniques of Hydroponic Anthurium Hydroponic Planting Methods
Before growing soil-grown anthurium hydroponically, it must first be acclimated so that it grows new roots in water, and then it can be placed in water for hydroponic cultivation.
1. Dig the potted anthurium out of the soil, cut off rotten roots, fibrous roots, and old leaves, wash it clean with clear water, put it into a potassium permanganate solution to disinfect, and then rinse the anthurium again with clear water. If using a transparent glass container for hydroponics, it is best to cover the outside of the glass with a black plastic bag to prevent strong light. Cover the top with a transparent convenience bag (to keep warm and retain moisture). Place it in a spot with scattered light, and keep the temperature above 10 degrees.
2. During acclimation, change the water frequently. In the first half month, do it once every 3 days; in the second half month, once a week. Every time you change the water, add nutrient solution once, and the nutrient solution should be selected specifically for hydroponic flowers. After one month, the anthurium 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. If the hydroponic flowerpot is semi-transparent, it will be somewhat better. Carefully put the anthurium roots into the hydroponic basket; river stones or expanded clay pebbles can be placed in the basket to fix the plant's position. 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, change the water according to the actual situation. When there are many impurities in the water, it should be changed. After a period of time, the hydroponic flowerpot should also be cleaned. Nutrient solution should not be added too frequently, because it will cause eutrophication of the water, speed up the reproduction of microorganisms in the water, and cause the oxygen content of the water to drop sharply, which is not conducive to plant growth.
5. If a larger flowerpot is used for hydroponic anthurium, small fish can also be kept in the water. The plant and fish mutually benefit each other and also form a corresponding scene. It can be said to serve two purposes at once.
How to Manage
After adding the nutrient solution, it should also be left to sit as described above before use. On one hand, the chlorine in tap water can volatilize; on the other hand, water that has been left to sit can stay consistent with room temperature. Do not put the water that has been left to sit in the sun, to avoid the growth of green algae. If you use cooled boiled water, that is also feasible. When growing anthurium hydroponically, the speed of inducing new roots takes a relatively long time compared with plants such as Aglaonema. However, its root system is quite vigorous; once hydroponic roots form, it is extremely easy to care for. Therefore, you should choose robust, virus-free anthurium plants. They can be disinfected with agricultural streptomycin, and then acclimated with a flower nutrient solution.
Disease Prevention and Control of Hydroponic Anthurium
Anthurium sometimes shows premature flower senescence, deformity, adhesion, splitting, vitrification, and blue spots. These are mostly physiological diseases caused by improper management of fertilization, potting soil, and air humidity, or by varietal reasons. The prevention method is to improve cultivation management, fertilize reasonably, and provide appropriate ventilation.
The main pests and diseases of potted anthurium include bacterial wilt, leaf spot disease, root rot, Cylindrocarpon spp., Cylindrocladium spp., nematodes, red spider mites, aphids, lepidopteran pests, whiteflies, scale insects, snails, and more.
Anthracnose
Anthracnose is one of the common diseases of anthurium. The pathogen is a fungus of the genus Gloeosporium or Colletotrichum. The former's symptoms are round brown lesions forming along the leaf veins, after which the lesions join together to form large lesions with brownish-yellow edges, and the diseased part finally dries up. The latter is similar to the former, with black setae growing on the acervuli, and it can also cause flower rot, forming black necrotic spots on the spadix. High humidity is the main cause of this disease. The control methods are chemical control and strengthened cultivation management. It is necessary to ventilate and let in light frequently, avoid water or air-conditioning condensate splashing on the leaves, and promptly remove diseased leaves.
Red Spider Mites
Symptoms of red spider mite damage: mainly causing leaves and flowers to fade, affecting the marketability of leaves and flowers. In the early stage of damage, pesticide control can be sprayed. The control agents include: dicofol, propargite, omethoate, and fluvalinate, etc.
Bacterial Wilt
Bacterial wilt is a bacterial disease caused by Xanthomonas, and can infect leaves and spadix. In the early stage of onset, water-soaked, semi-transparent irregular small spots form on the leaves, then turn black, with a bright yellow edge outside, and the area around the lesions loses green color. This pathogen can cause systemic infection, manifested as old leaves turning yellow, petioles breaking, and vascular bundles turning yellow. The control method is to strengthen cultivation management, supplement with chemical control, promptly remove diseased plant residues, and burn them. During cultivation management, minimize artificial wounds and minimize the use of ammonium nitrogen fertilizer. Generally, in the early stage of onset, spray agricultural streptomycin or new phytomycin.
Bacterial Leaf Spot
The symptoms shown are of one type on leaves and flowers: in the early stage, water-soaked spots can be seen on the back of leaves and flowers, and later brown spots appear at the leaf margins, accompanied by yellow halos. Another type is that the bacterial infection starts on the stem and rapidly expands to the entire plant by infecting cells through vascular bundles. In the early stage, it can be found that the color of new leaves is dull, because the vascular bundles are blocked by bacteria, hindering the flow of water and the transport of nutrients within the plant, making the leaf color dull and the leaves yellow. In a relatively short time, this type of infection will cause flower stalks and leaves to fall from the plant, and the growing point rapidly rots with bacterial ooze flowing out.
There is no specific cure for bacterial diseases, so prevention is mainly the priority:
Environmental Prevention
Strengthen the control of greenhouse temperature (the ideal reproduction condition for bacteria is around 30 degrees), the sanitary environment, and the movement of personnel and tools in the production area, etc.
Fertilizer Prevention
During plant growth, try not to use nitrogen fertilizer in high NH4 form. Remove or isolate diseased plants.
Leaf blight nematode disease is caused by infection by nematodes of the genus Aphelenchoides, mainly infecting the roots and leaves. The symptoms are necrotic spots or brown spots forming along the leaf veins, the roots enlarging, and finally the entire leaf drying up. The control method is mainly to strengthen seedling quarantine, select robust seedlings, and properly disinfect the cultivation substrate.

How to Grow Hydroponic Anthurium What to Do If Hydroponic Anthurium Leaves Turn Yellow
The leaves of anthurium are jade-green and the flowers are brilliantly colored, and hydroponic anthurium looks even more ornamental. However, hydroponic anthurium has relatively high requirements, and it is prone to the phenomenon of leaves turning yellow during cultivation. So how should we grow hydroponic anthurium? Below, we will introduce relevant knowledge about hydroponic anthurium cultivation.
How to Grow Hydroponic Anthurium
1. Transplanting. Dig the potted anthurium out of the soil, cut off rotten roots, fibrous roots, and old leaves, wash the roots clean with clear water, put them into a potassium permanganate solution to disinfect, and then rinse the anthurium again with clear water. If using a transparent glass container for hydroponic anthurium, it is best to cover the outside of the glass with a black plastic bag to prevent strong light. Cover the top with a transparent convenience bag (to keep warm and retain moisture). Place it in a spot with scattered light, and keep the temperature above 10 degrees.
2. Changing water. During acclimation, change the water frequently. In the first half month, do it once every 3 days; in the second half month, once a week. Every time you change the water, add nutrient solution once, and the nutrient solution should be selected specifically for hydroponic flowers. After one month, the anthurium 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.
Later, because the root respiration of anthurium is very strong, it is necessary to change the water for the anthurium regularly, remove the mucus secreted from the anthurium root system and some algae plants, and cut off old roots and rotten roots. This also helps increase the dissolved oxygen content in the water. Generally, change the water once every 2 or 3 days, and in winter it can be changed once a week, adding nutrient solution once each time you change the water.
For acclimated hydroponic anthurium, change the water according to the actual situation. When there are many impurities in the water, it should be changed. After a period of time, the hydroponic flowerpot should also be cleaned. Nutrient solution should not be added too frequently, because it will cause eutrophication of the water, speed up the reproduction of microorganisms in the water, and cause the oxygen content of the water to drop sharply, which is not conducive to plant growth.
3. Potting hydroponic anthurium. If the hydroponic flowerpot is semi-transparent, it will be somewhat better. Carefully put the anthurium roots into the hydroponic basket; river stones or expanded clay pebbles can be placed in the basket to fix the plant's position. Add water to half or 2/3, so that the roots not submerged in water can still breathe from the air. When growing hydroponic anthurium, just immerse 1/2 of the anthurium root system in water, and expose the other roots to the air so that the anthurium roots can breathe. Insufficient dissolved oxygen in the water will cause anthurium root rot.
4. Light and temperature. Anthurium likes warm, semi-shaded environments, and avoids exposure to strong sunlight. During the process of growing hydroponic anthurium, pay attention to the placement position. It is best to place it in a spot that is ventilated and breathable and can avoid strong light. In summer, the ambient temperature around hydroponic anthurium should not be higher than 28°C; in winter, the cultivation temperature for hydroponic anthurium must not be lower than 14°C. Below this temperature, the anthurium will suffer cold damage.
5. If a larger flowerpot is used for hydroponic anthurium, small fish can also be kept in the water. The plant and fish mutually benefit each other and also form a corresponding scene. It can be said to serve two purposes at once.
What to Do If Hydroponic Anthurium Leaves Turn Yellow
Reasons Why Hydroponic Anthurium Leaves Turn Yellow
In fact, the most important thing for hydroponic anthurium is water. The plant obtains most of its nutrients from the water, and another part relies on photosynthesis to accumulate nutrients. If water is not added in time in the hydroponic container, the nutrients in the water are insufficient, or the light is insufficient, any one of these will cause anthurium leaves to turn yellow.
Solutions for Hydroponic Anthurium Leaves Turning Yellow
1. Add water in time
Frequently check the water level in the hydroponic container. When the water level is below 1/3 of the roots, water needs to be replenished in time. As long as there is enough water in the hydroponic container, there is no need to sprinkle water on the leaf surface every day. If the leaves are dirty, gently wipe them with a damp cloth.
2. Add nutrient solution at the right time
For hydroponic anthurium, how often to change the water does not matter much; the key is to grasp the content of the nutrient solution in the water. As time goes on, the water will be absorbed by the plant, and the daily process of adding water has actually already completed the step of changing the water.
Therefore, in order to ensure sufficient nutrients in the water, when adding water to the container, drip in a few drops of nutrient solution. As for exactly how much to drip, you can be flexible according to the growth condition of the anthurium. At minimum, drip two drops each time, then observe the plant's growth. If normal, maintain the original state; if growth is poor, add appropriately.
3. Supplement sunlight
Compared with soil cultivation, hydroponic anthurium needs more sunlight. Ensure 2-3 hours of direct sunlight every day (avoid direct sunlight at noon). In winter, more sun exposure can prevent branches and leaves from becoming weak and turning yellow.
