How to Grow Anthuriums
The best time to grow them is during spring or summer. Also, putting them in containers is the best way to go for house plants such as anthuriums. Depending on the growth habit of the species or cultivar you like, the container and location would vary. For example, the Anthurium andraeanum has an erect stature and is grown in the usual plant pots. On the other hand, types that have strap-like foliage, such as A. vittarifolium and A. pendulifolium, are grown in hanging pots.
Some of the things you need to consider when choosing the right pot are your plant’s growth habits, leaf and flower structure, and sensitivity. Along with choosing the right container is choosing where to place your plant. Most types of Anthurium prefer a humid and bright location with good airflow, which is why they are often placed near windows.
The easiest and most efficient way to propagate anthuriums is by division. Through time, they tend to grow and produce new plants especially when all their growing requirements are met. By this time, overcrowding may be observed. A sign of overcrowding is having a denser plant but slower growth. Overcrowding sign shows that it is time to divide your plant.
In dividing, you will need a knife, garden trowel, pot, and potting mix. The first thing to do is to loosen up the soil and uproot the clumped plant. Lightly shake the root part to have a clearer view. Select the plants to be separated and carefully detach them. Using a knife would be easier but remember to avoid cutting the major roots. Lastly, plant anthurium in its new pot with the potting mix.
Give the new plant the same care. If the repotting is successful, flowers may be observed after a year. An additional tip is to repot annually, preferably during spring.
Knowing the origins of your plant is the best way to determine which type of soil they would need. For anthuriums, they are mainly grown in tropical regions with dry and loose soil. Some types are even epiphytic, meaning they survive by clinging on to trees.
With this being said, the best growing media for anthuriums are loam to sandy loam soils. Some add mulch and sphagnum moss to improve the soil texture. If you are new to the gardening scene, there are readily available planting mixes in the market. Remember to get a mix that has good drainage, is disease-free, and is loose. If you have available soil, performing soil tests will help you know what to improve. Also, remember to pasteurize the soil to get rid of soil-borne pathogens.
Pruning is only done as needed. It is performed with the use of sharp pruning shears to remove dead and damaged plant parts. This act is beneficial for the health of the plant and gives off better aesthetics.
Repotting and Transplanting
Repotting and transplanting have the same steps as propagating but without dividing. If your anthurium plant has already become too big for its pot, choose a pot one size bigger than the old one. If it is your first time to repot, here are some steps you can follow:
- Using a garden trowel, loosen the soil on the edges of the pot. Keep the soil in the middle intact.
- Fill ⅖ of the pot with soil or growing mix.
- Tilt the pot and guide the plant as you remove the plant from its old pot. This part can be messy especially when the soil is loose. Try to keep as much soil root bound as possible.
- Plant the anthurium on its new pot and fill the spaces with soil or mix.
- Using your fingers, lightly press on the soil around 1.5 inches away from the base. Do not press too hard to avoid compacting the soil.
How to Care for Anthurium Plants
Follow our Anthurium care guide to grow healthy plants:
Anthuriums love moderate amounts of water. Also, it prefers slightly dry soil. Do the finger test to know when it is time to water. Stick your finger down the soil for up to 6 cm deep. If that part of the soil is dry, you may water your plant again.
They love basking in indirect bright light but not directly under the sun. Some growers put their anthuriums near windows to get that bright light. On the other hand, inadequate light exposure will lead to slower growth of the plant.
Temperature and Humidity
Since they are houseplants, the ideal daytime temperature for them is around 21 to 27 degrees Celsius. At night, it prefers a colder temperature of up to less than 10 degrees Celsius. The common types can thrive in 60-80% humidity but there are rare types that prefer up to 90% humidity. In general, they love places with high humidity.
There are no special fertilizers needed for this plant but regular application of complete fertilizer will be beneficial. As houseplants, they are bound to have fewer nutrients in their soil making it deplete faster through time. To avoid malnutrition, apply diluted complete fertilizer monthly. The mixture should have one part fertilizer and four parts water. Also, time the application during the actively growing stages of the plant which is usually around spring and summer.
Pest and diseases
Anthuriums are commonly affected by fungal and bacterial diseases, which are commonly seen in masse. Here are the most common diseases:
Black Nose Disease
Brought upon by the fungus, Colletotrichum gloeosporioides, this disease causes the blackening of the spadix and it can progress to rotting of the whole spadix. Also, leaves and stems may be affected during serious infestations. It is prominent in humid areas wherein the fungus gets inside the plant’s system through cuts and damages.
Rhizoctonia Root Rot
Rhizoctonia solani is the causative organism of this disease, which lives in soils and could survive there for years despite the lack of a host. Your plant might have this if it exhibits symptoms such as early death of younger stems or mushy stems.
Phytophthora and Pythium
The fungal pathogens for this disease are the Phytophthora nicotianae var. parasitica and Pythium splendens. Common symptoms of this disease include yellowing of the leaves and root damage. If it gets worse, black lesions on the leaves may be seen. Also, you will observe that the plant does not grow despite giving all the necessary growing requirements.
Caused by the bacteria, Ralstonia solanacearum, this disease makes the anthurium’s foliage yellow during its early stages. As the disease progresses, it destroys the plant’s vascular system making the stems brown and mushy. To know if it’s caused by a bacteria, cut an infected part and dip it in a clear glass filled with water. Observe closely to see bacterial ooze.
Xanthomonas axonopodis pv. dieffenbachiae is this disease’s causal organism. It makes the plant’s foliage turn yellow and dull. Also, there are noticeable mushy brown lesions on different parts of the leaf. This disease occurs in moist environments, especially if there are stagnant droplets of water on the surface of the plant.
Control for Anthurium Diseases
Since the mentioned diseases are spread in a moist environment, remember to keep the plant surfaces dry and avoid overwatering. Pasteurization of the soil is also crucial to make sure that soil-borne diseases are killed. Another way to prevent the spread of diseases is by isolating infected plants and cleaning garden tools after usage.
The use of chemical pesticides may bring benefits especially for anthuriums in large numbers. There are protective fungicides present in the market too.
Common Anthurium Insect Pests
Aphids, mites, thrips, and mealybugs are the most common insect pests for anthuriums and other household plants. If the infestation is still low, you can pluck the pests manually or using home remedies. The use of soap and water to wash the plants is one of the home remedies for small infestations.
However, as the infestation progresses, remember to isolate the infested plants and clean all the gardening tools. Another control measure would be the use of pesticides. Some pesticides are household plants friendly and are readily available in the market.
As a general rule in using pesticides, read the recommended rate and make sure to follow the instructions.
