What are the key points to note when growing Anthurium as a houseplant at home?
Key points for growing Anthurium
1. Temperature
When growing Anthurium at home, keep the temperature as steady as possible. The optimal growing temperature for Anthurium is 16-24°C, and the minimum temperature should stay above 12°C. In an ordinary home with heating, this is easy to achieve. But at the same time, you must note that the pot must not be placed on top of a radiator or too close to one. When the summer temperature exceeds 30°C, move the plant to a well-ventilated room on the relatively north side, and you can spray water around the plant to cool it down.
2. Light
Normal growth of Anthurium requires plenty of diffused light. For home growing, generally note the following: in summer, avoid strong direct light on the leaves and flowers; in autumn and winter, when conditions allow, move it near a window to increase light. You also need to rotate the plant regularly to ensure it receives light evenly and to promote a full, rounded crown shape.
3. Humidity
Normal growth of Anthurium requires around 70% air humidity, which is generally very hard to achieve in an ordinary home. You can wipe the leaves wet several times a day with a clean damp towel, or spray water around the plant regularly to increase air humidity. (But never sprinkle water on the flowers, as this affects their ornamental quality.)
4. Watering and fertilising
Under normal growth conditions, water the potting soil once a week, letting it dry out and then get wet again. Generally follow the principle of not watering until the soil surface is dry, and when you do water, water thoroughly. In spring, autumn and winter, you can appropriately reduce the number of waterings and the amount of water. Every half a month, apply a 7-8% special nutrient solution or a fertiliser water diluted 500 times along with watering.
5. Pruning
Generally, as Anthurium grows, the leaf stalks at the base gradually degenerate; when the stipules dry out, they can be cut off promptly. When the flower stalk turns yellow after flowering, it must also be cut off as soon as possible from the base, leaving a 2 cm protective stub.
How to grow potted Anthurium, and how to propagate Anthurium
Everyone should have seen Anthurium; it appears often in our daily lives, and many people even grow potted Anthurium at home. Its bright red flowers are unique and delicate, and paired with its emerald green leaves, it is very beautiful and elegant. So do you know how to grow potted Anthurium correctly? Let's learn about it together below!
How to grow potted Anthurium
1. Soil selection
For home growing, you can buy ready-mixed potting soil directly at a garden shop. After getting home, add a small amount of expanded clay pellets or dry tree bark to the nutrient soil you bought. Expanded clay pellets : dry tree bark = 2:1. However, the soil for growing Anthurium must maintain good permeability and good drainage.
Be sure to sterilise the soil before planting. However, if the soil you prepared was bought as professional soil from a specialist shop, you can skip this step. Sterilising is to give Anthurium a smaller chance of suffering from pests and diseases in the later stages of growth.
2. Temperature requirements
The most suitable growing temperature for Anthurium is 14-35°C. When the winter temperature is below 10°C, Anthurium is easily frostbitten, so increase the temperature promptly. When the summer temperature is above 35°C, sprinkle water around the Anthurium to cool it down.
3. How to fertilise
Anthurium likes fertiliser and has a higher demand for magnesium fertiliser. It is best to go to a professional flower shop and buy a foliar fertiliser with a relatively high magnesium content to use together. Or choose a water-soluble compound fertiliser diluted into a liquid fertiliser to feed Anthurium. Spray once a week during the growing period. When fertilising, stick to the principle of "light fertiliser applied frequently"; better less than more, because too much will directly burn the seedlings~
4. Watering cycle
Watering Anthurium needs to be done according to how dry the potting soil is. According to the pattern summarised by flower growers, in spring and autumn we should water once every three days. In summer, once every two days, and in summer note that at noon you should use a sprayer to mist the leaves to increase humidity. In winter, watering once every 5-7 days is enough.
When the weather is cold, water between 9 a.m. and 4 p.m. When watering, note to alternate between dry and wet, and avoid watering when the plant is severely short of water, as this affects the growth and development of Anthurium.
5. Note to control humidity
High temperature and high humidity is the environment Anthurium likes. Humidity is related to temperature; when the room temperature is above 28°C, we need to manually increase indoor humidity. You can use a humidifier or sprinkle water to add humidity. When the temperature is below 20°C, just maintain the indoor ambient humidity; there is no need to water.
In winter, even if the indoor temperature is relatively high, it is best not to lower the temperature and retain moisture too much. If the leaves are too wet at night, the plant's cold resistance is reduced, causing frostbite and making it harder to get through the winter.
How to propagate Anthurium
1. Seed propagation: In breeding Anthurium, sowing seeds is the main way to obtain new Anthurium varieties. The Anthurium fruit is a berry type and must be sown immediately after harvest. Before sowing, remove the fruit skin and wash off the flesh to avoid the skin and flesh rotting and becoming mouldy and affecting the seed germination rate.
The sowing method can use the pure sand germination method: sow the seeds individually in clean river sand at a sowing depth of 0.5-0.8 cm, maintain a certain humidity, and generally they will germinate in about 15 days, with new leaves soon growing out. When they have grown to 5-6 leaves, they can be transplanted into a substrate of pure perlite mixed with peat soil or coconut coir at 1:2 for temporary planting.
2. Division propagation: Division propagation is best chosen in the cool spring and autumn. When dividing, be careful not to damage the mother plant. Do not divide side shoots that are too large, do not divide side shoots that are too close together, and do not divide side shoots that are too weak and small. Choose side shoots that are relatively easy to separate from the mother plant and are relatively robust, with at least 2 or more main roots.
Key points to note for home potted Anthurium
1. Proper humidity for a beautiful posture
When growing Anthurium, note to retain moisture. Only after truly keeping the humidity Anthurium needs during its growing period under our control can we have enough confidence to let Anthurium grow robustly.
2. Insufficient sunlight makes flowering difficult
Anthurium likes sunlight, and with insufficient sunlight during the growing period it is hard to flower. However, Anthurium is not suited to direct sunlight, which burns the leaves. The best method is to put Anthurium in a shaded place and let it receive diffused light; just note that it must not be too shady. This avoids burning from strong light while still having refracted sunlight for photosynthesis.
3. Unsuitable temperature makes it hard to keep alive
Growing Anthurium requires attention to temperature control. The maximum temperature should not exceed 35°C, and the minimum temperature should not be lower than 14°C. Below 10°C, cold damage can occur at any time, so 18-28°C is best. In summer the temperature is high, so note ventilation and sprinkling water; in winter, grow it in a greenhouse.
The habits of Anthurium
Wild Anthurium often grows epiphytically on trees, sometimes on rocks or directly on the ground. It likes warm, humid, semi-shaded environments and avoids direct sunlight.
Anthurium is suitable for growing in a warm, humid environment with good drainage, and is afraid of drought and strong direct sun. The most suitable temperature for growth is 26-32°C, and the most suitable night temperature is 21-32°C. It can withstand a maximum high temperature of 35°C and can tolerate a low temperature of 14°C.
Anthurium growth needs appropriate sunlight, but avoids direct sunlight. It is suitable for growing in an environment with 70%-80% air humidity.
Foliage-type Anthurium varieties need semi-shade or shade, and the temperature should be a bit higher. Generally the minimum temperature should not be below 16°C. In winter, maintain a room temperature of 20-22°C and keep air humidity high.
Through the above content, I believe everyone has gained some understanding of potted Anthurium care. Anthurium's flowering period is very long, and Anthurium is not only beautiful and pretty but also very easy to care for. As long as you master the correct fertilising and watering techniques, it basically does not take much time to manage.
How to grow home Anthurium, and how to grow home Anthurium
Home Anthurium has fresh, vivid colours, and the flower shape is beautiful and special. Many families like to grow home Anthurium to enjoy its graceful appearance while adding a touch of greenery to the home. Home Anthurium's growth habits are relatively special, and it can be propagated by grafting. Let's learn below about how to grow home Anthurium. How to grow home Anthurium

The pests that most often occur on Anthurium are red spider mites, nematodes, cabbage caterpillars, whiteflies, thrips, snails and scale insects, among which red spider mites, nematodes and cabbage caterpillars are especially predominant. However, Anthurium is very sensitive to insecticides. If insecticides must be used, it is best to choose low concentrations. One thing to note in particular is that all copper-containing pesticides, such as dimethoate, dichlorvos, malathion, parathion, methamidophos and so on, will poison Anthurium, so it is best not to use them.How to prune home Anthurium
To keep Anthurium from consuming too much, we should promptly cut off dead branches and remaining branches during the growing period. As for the pruning techniques for Anthurium, there is the saying of "three adjustments and two cuts", namely adjusting direction, adjusting the plant, cutting off suckers, cutting off flower buds, and cutting off old flowers.
