How to grow Anthurium? An analysis of the key cultivation techniques for Anthurium
Many people enjoy growing flowers, especially those with auspicious meanings, such as Anthurium and Guzmania, but some beginners are not very familiar with flower cultivation, so the editor is here to share some experience on growing Anthurium!
Anthurium: its flower language means realizing great ambitions, passion, and warm blood. Anthurium is a perennial evergreen herbaceous plant. The plant height is 20-70 cm, the stem is extremely short, and aerial roots are easily produced. The leaf stalks are hard and slender, and the leaves are bright green, long-elliptic and heart-shaped. The flower stalk is usually higher than the leaves, with a spadix inflorescence at the top; the spadix is golden yellow and upright, and the spathe spreads open, broadly heart-shaped, with a wavy wrinkled surface. The flowering period is long, and under suitable environmental conditions it can bloom in all four seasons.
Light: It likes a semi-shaded environment and is afraid of direct exposure to strong sunlight in summer and autumn. Generally, when placed indoors, it is best to put it near a window. In a spacious office, if the fluorescent lights are on all day, then Anthurium can be placed on any desk for a long time.
Temperature: It likes a warm and hot climate. The suitable growth temperature is 20-30 degrees, and its cold tolerance is poor. In winter, the temperature is best kept above 8 degrees.
Water: It likes a warm and moist environment. Usually, when the surface of the growing medium looks dry, you can water it, and the same applies in winter when there is heating indoors. If there is no heating indoors in winter, you can wait until the upper part of the medium is dry to about 2 cm deep before watering.
Anthurium also likes high relative air humidity, with 70%-80% being best. Therefore, when the air is dry, spray water on the leaves several times a day. To avoid trouble, it is best to place the flower pot on a shallow dish filled with pebbles and water.
Fertilizing: Starting from spring when the leaves begin to grow, and continuing until autumn, apply a small amount of compound fertilizer granules with a nitrogen:phosphorus:potassium ratio of 1:1:1 to the flower pot once every half month. Stop fertilizing in winter when the temperature is low.
Pruning: When old, yellowed leaves appear at the lower part of the plant, use your fingers to peel the leaves together with the leaf stalks from the base. Spent flowers after fading should also be removed in the same way together with the flower stem, or you can pinch the spent flower stem tightly with your fingers and pull with a bit more force, and the spent flower stem can be broken off from the base.
Propagation: Because small plantlets grow beside the mother plant, these small plantlets can be separated from the mother plant and then planted. This division propagation is usually carried out together with repotting.
Repotting: Every spring, plants that have bloomed should be repotted, and division propagation can be done at the same time. Because the stem will keep growing longer, the mother plant will also become taller and taller. For a mother plant that has grown too tall, it can be cut back short, but the stem must carry several adventitious roots, and then it can be planted directly. The shortened mother plant can also be kept, because it will continue to sprout side branches and bloom.
That covers the question of growing Anthurium. The so-called "flowers" of some plants have ornamental value, but in fact they mainly refer to the brightly colored bracts (or called bract leaves) produced when they bloom, such as Anthurium. Because of this, many people want to grow Anthurium.
How to grow Anthurium Precautions for growing Anthurium
Anthurium can be grown as a potted plant. A single potted flowering period can last as long as 4~6 months, and it can bloom year-round. Many people grow it at home because it has high ornamental value. It is like an open red palm, with a small golden-yellow spadix standing upright on the palm, making it especially eye-catching. Academically, it is called a "spathe." Below let us take a detailed look at how to grow Anthurium and the precautions for growing Anthurium.
How to grow Anthurium
How to grow Anthurium well is a meticulous task. You need to consider drainage at the bottom of the pot, and add more broken bricks, tiles, gravel, and similar materials. After planting, water thoroughly and place it in a cool place to recover; just spray water on the leaves 1~2 times a day and maintain the surrounding air humidity. Repot once every 1 year in spring, remove dead roots and some old roots to encourage new root growth, and add some new soil at the same time.
Precautions for growing Anthurium
Humidity
Normal growth of Anthurium requires about 70% air humidity, which is generally difficult to achieve in ordinary home cultivation. You can use a clean wet towel to wipe the leaves wet several times a day, or spray water around the plant regularly to increase air humidity. (But be sure not to sprinkle water on the flowers, so as not to affect the ornamental quality.)
Watering and fertilizing
Under normal growth conditions, water the growing soil allowing it to dry and become wet alternately each week. Generally follow the principle of not watering when the soil surface is not dry, and watering thoroughly when you do water. In spring, autumn, and winter, the frequency and amount of watering can be appropriately reduced. Every half month, apply a special nutrient solution at 7-8% or a fertilizer solution diluted 500 times along with watering.
Pruning
Under normal circumstances, during the growth of Anthurium, the leaf stalks at the base gradually degenerate, and when the stipules become dry they can be cut off promptly. After flowering, when the flower stalk turns yellow, it must also be cut off as soon as possible from the base, leaving a 2 cm protective stub.
Temperature
When growing Anthurium at home, the temperature should be ensured as much as possible. The optimum growth temperature for Anthurium is 16-24°C, and the minimum temperature should be kept above 12°C. If an ordinary household has heating facilities, this condition is easy to meet. But at the same time, note that the flower pot must not be placed on top of a radiator or too close to a radiator. When the summer temperature exceeds 30°C, the plant must be moved to a relatively north-facing room with good ventilation, and water can be sprayed around the plant to lower the temperature.
Light
Normal growth of Anthurium requires sufficient scattered light. For home cultivation, generally note the following: in summer, avoid strong direct light on the leaves and flowers; in autumn and winter, when conditions permit, move it near a window to increase light. The plant also needs to be rotated regularly to ensure it receives uniform light and to promote a full, rounded crown shape.

How to grow Anthurium Precautions for growing Anthurium
Anthurium is a flower variety with extremely high ornamental value and has long received widespread attention. So how do you grow Anthurium? I believe everyone would also very much like to know the answer to this question. Then next let us take a look at what methods there are for growing Anthurium. By learning about Anthurium knowledge, we can better apply it to daily life. So next let us take a look at how to grow Anthurium.
Methods for growing Anthurium
(1) Cultivation method: When potting seedlings, in terms of procedure, the growing medium should be prepared first. The medium should be chosen for good permeability. In China, peat and perlite are generally used (at a ratio of 3:1), and the medium still needs to be sterilized. If old pots are used when potting, the pots should also be sterilized to avoid cross-infection by pathogens and insect eggs. For the pots, you can choose black plastic bag culture pots, or you can directly use plastic pots. But no matter what kind of pot is used, one with good drainage performance should be chosen. If the drainage holes are blocked, clear them before potting. The planting requirement is the same as low planting, that is, not too deep and not too shallow, and the stem tip should not touch the medium or debris.
(2) How to fertilize for home cultivation: Preparing your own nutrient solution for home maintenance is rather cumbersome. Therefore, powders already formulated according to nutrient requirement elements are available on the market, and when used they can be mixed with water in proportion. There is also a slow-release fertilizer on the market now. Bury it in the soil according to the instructions, and afterward it dissolves as you water, for the Anthurium to absorb. Apply 1-3 grams at a time, and its fertilizer effect can last up to 3 months. These fertilizers have one thing in common: the required nutrient elements are complete. Different growth stages have different formulas, and they are clean and hygienic. In fact, slow-release fertilizer is also used in large-scale cultivation. Especially for those maintained outdoors, fertilizing before rain is as good as not fertilizing at all, and using slow-release fertilizer can avoid this. In home maintenance, you can also compost hoof and nail pieces and sesame paste residue, and if you add some ferrous sulfate to it, the so-called alum fertilizer water will have an even better effect. In home fertilizing, you should grasp the principle of dilute rather than concentrated, and small amounts more often.
(3) How to apply water: Anthurium likes an environment with higher humidity. The humidity mentioned here refers to the relative humidity in the air, not only the water content in the growing medium. Humidity is also a variable, because when humidity rises and dry winds increase (especially in northern China), if water is not replenished, then humidity will decrease. Generally speaking, the humidity required by Anthurium should be kept at 70%-80% (air temperature 20-28°C). The level of humidity can regulate humidity for Anthurium, that is, regulate the transpiration on the leaf surface of Anthurium. If relative humidity is too low, causing drought and water shortage, the edges of the leaves and spathes will become dry and withered, and the spathes will be uneven. The water temperature for watering Anthurium should be kept at about 15°C (including the nutrient solution applied). 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-fleshy, and the roots themselves store a large amount of water. Too much water in the medium causes oxygen deficiency in the medium, obstructs root respiration, and long-term overly wet conditions will cause root rot. The above explains the quantitative standard for moisture. Growing Anthurium at home makes it very difficult to achieve the effect of a greenhouse, and this is also an obstacle for households buying Anthurium. But we can create a humidity environment suitable for Anthurium growth through the following methods. For example, if the household also keeps ornamental fish, you can place the Anthurium on top of the fish tank, with a tray under the pot, or beside the fish tank. You can also use two flower pot trays: place a slightly larger tray below and fill it with water, then use a smaller tray upside down on the tray with water, and then place the potted Anthurium on it, taking care that the bottom of the pot does not touch the water surface. You can also use discarded cola bottles or mineral water bottles, fill them with tap water, let them sit for 3-4 days, then pour the water into a spray bottle and spray the leaf surface of the Anthurium. In summer, spray once at 10:00-11:00 and once after 15:00, but the pH value of the sprayed water should be low. The water used for watering should also be left to sit as above before use. On one hand, the chlorine in tap water can volatilize; on the other hand, the water that has been left to sit can remain consistent with room temperature. Do not put the water left to sit in the sun, to avoid the formation of green algae. If you use cooled boiled water, that is also feasible.
Methods for growing Anthurium hydroponically
1. Nutrient solution suitable for Anthurium survival
It is recommended to choose a foliage plant nutrient solution. It must be replaced once every 7-10 days. Regularly changing the water for Anthurium can remove the mucus secreted by the Anthurium root system and some algae. In summer, when the temperature is high, change the water more frequently than in winter. It is recommended to change the water for Anthurium once every 2-3 days. Do not fill the water too full, to prevent Anthurium root rot. It is best to keep about half of the Anthurium root system exposed above the water surface. This can ensure the roots' absorption of oxygen.
2. Light and temperature required for hydroponic Anthurium
Anthurium likes semi-shade, and a warm, moist environment is also one of the requirements for Anthurium's growing environment. It is afraid of exposure to the sun, so during cultivation special attention should be paid to the placement location. It is best to place it in a spot that is ventilated and breathable while avoiding strong light. In summer, when growing Anthurium hydroponically, note that the surrounding environment temperature must not be higher than 28 degrees. Relative air humidity should be maintained at 80%. When the weather is relatively dry, spray an appropriate amount of water on the leaf surface of the Anthurium. In winter, the temperature for hydroponic Anthurium must not be lower than 14 degrees. Below this temperature, Anthurium is prone to cold damage. Be sure to keep it warm and raise the temperature. Also control the air humidity at about 80%, and be sure not to place Anthurium outdoors, otherwise it is very easy to cause cold injury to Anthurium.
3. Oxygenation methods for hydroponic Anthurium
The difficult problem faced by hydroponic Anthurium is that if the dissolved oxygen in the water is low, it will cause root rot in Anthurium. Therefore, during hydroponic cultivation, the oxygen content in the water must be increased in time. Among these, the simplest method is vibration: fix the flower plant with one hand, and hold the container with the other hand and gently shake it more than 10 times. After shaking, the dissolved oxygen content of the nutrient solution can increase by about 30%. Or add 1% hydrogen peroxide (3% hydrogen peroxide solution) to the nutrient solution. If conditions permit, a miniature submersible pump or oxygenation pump can also be used to oxygenate the nutrient solution.
