Why My Anthurium Cirinoi Is Leaves Turning Yellow?

What is Anthurium Cirinoi?

Anthurium Cirinoi is a magnificent plant with a huge growth habit. It is less well-known than the closely related Anthurium Warocqueanum, but is equally as dazzling in our opinion. All plants for sale are cultivated from seed collected from the mother plant in Hawaii by a friend of ours. It is a very magnificent example.

The leaves are large and leathery, with a thin, slightly wavy margin. The leaves are pale with a dark green background and covered in raised, tan colored protrusions.

The flowers are white, held on a long stalk above spreading lateral bracts. The petals are little more than two ‘lips’ which partially wrap around the tiny stamens. As the flower ages it turns yellow from the base up until all that is left is the lip of the flower.

Cirinoi is fairly easy to grow, but does enjoy the same conditions as Anthurium Warocqueanum. It has a good sized root system and requires plenty of water and fertilizer to grow to its full potential. However, we have found that it appreciates some shade from direct sunlight during the summer months.

If you are looking for a magnificent plant with huge leaves and interesting flowers, this is definitely a plant to look out for in the future.

How do you care for Anthurium Cirinoi?

Anthurium Cirinoi is a plant with a large tan colored root system. It produces new leaves and flowers from this root system. The following are factors to consider when caring for Anthurium Cirinoi;

Light

Anthurium Cirinoi is a plant which grows in the forests of Hawaii and as such it enjoys some shade from direct sunlight. In summer months, Anthurium Cirinoi enjoys partial shade, avoiding direct sunlight. This helps to slow down growth and allows its foliage to remain lush and healthy while protecting it from sun burn.

Soil

Anthurium Cirinoi needs a soil rich in nutrients, with a large amount of organic material. A mix of soil and compost is ideal. We have found that Anthurium Cirinoi also enjoys being grown in a bog garden, where it can be kept permanently moist through the use of an automatic watering system.

Water

Anthurium Cirinoi is a slow-growing plant which requires plenty of water. Watering Anthurium Cirinoi regularly means the plants will continue to produce new leaves, flowers and roots for a long time.

Fertilizer

Anthurium Cirinoi has a high nutritional content and plants which have been grown indoors over a long period of time do not require additional fertilizer. Plants which are grown outside in direct sunlight need more nutrients and will benefit from them once they are exposed to more light.

Temperature

Anthurium Cirinoi enjoys a temperature of around 65oF. At this temperature plants are fully grown with good root system and maximum health. A temperature of 50oF is good for indoor plants. Plants that are growing outdoors need to be protected from temperatures below 40oF or frost.

Temperature fluctuations should be kept to a minimum, especially in the range of 40oF-60oF. This range can cause damage to the plant and should be avoided. A temperature fluctuation of more than 15 degrees per day should also be avoided, 50-55oF during the day and 45-50oF at night is best for Anthurium Cirinoi.

Humidity

Anthurium Cirinoi requires abundant humidity, which can easily be obtained by misting its leaves regularly. The plant does not like excessive humidity though, and will suffer in an extremely humid environment if situated in an area which is over-watered.

Repotting

Anthurium Cirinoi is a very large and slow-growing plant. It can be grown in a wide variety of containers, as long as the roots of the plant are supported by a soil-filled pot. Once the plant is sufficiently large, repotting into larger pots is advised.

Repotting Anthurium Cirinoi can be done in midwinter or whenever it has outgrown its pots. The soil inside the pot should always be loosen, but not removed all the way to the bottom of the pot.

Propagation

Anthurium Cirinoi can be propagated from both seed and vegetative cuttings. Seeds should be soaked in water and kept moist for a few days before planting. The seeds are very sensitive to drying out and will not germinate if this occurs.

Seeds should be sown on the surface of the soil in a lightly dampened pot, covered with a plastic bag to retain humidity. Germination will occur after about three weeks, when shoots appear above the soil line.

Pruning

Pruning is necessary in Anthurium Cirinoi to maintain the health of the plant. The ideal time to prune is during the growing season, spring or summer and while the plant is still outside. To do this, remove any leaves which are dead or diseased from the plant. Leave three or four leaves on each stem, removing them as needed when they yellow. Pruning is essential during autumn or winter for indoor plants.

 

Why my Anthurium Cirinoi is leaves turning yellow?

Anthurium Cirinoi has been known to suffer from leaf burn caused by whitefly. A few symptoms of this are that the plant leaves start to turn yellow and drop off, the plant starts looking sick and it can start losing size. The following are the causes of yellow leaves;

Overwatering: This is the main cause of leaf burn in Anthurium Cirinoi. Leaves which have no water and are suffering from being over-watered will turn yellow. It is recommended that Anthurium Cirinoi be grown on a bog garden which collects water via a system of pipes and pumps; this allows the plant to be watered on demand, avoiding over-watering.

Underwatering: Another cause of leaf burn in Anthurium Cirinoi is under-watering. This happens when the plant receives no water and is suffering from being over-watered. Anthurium Cirinoi which are over-watered will have yellow leaves which turn red, before eventually falling off.

Low light: Leaves which are not receiving enough light will also turn yellow. Anthurium Cirinoi which are in a low light situation need more light, this is simply achieved by moving the plant to a brighter area, or creating artificial lighting such as fluorescent tubes.

Low temperature: Leaves will also turn yellow when the temperature of the room is low. Here are some tips to keep the temperature of your Anthurium Cirinoi at a constant 55oF

The temperature in your home should be between 50 and 60oF at all times, adjust your thermostat accordingly. Air conditioning should not be used in Anthurium Cirinoi which are grown indoors, as it will cause them to lose their leaves.

Excess fertilizer: Freshly-cut stems of Anthurium Cirinoi should not be given fertilizer as it can cause the plant to go through brown leaf tips, which will eventually turn yellow. If they are to be given any fertilizer at all, it should only be some aged compost.

How often do you water your Anthurium Cirinoi?

Watering your Anthurium Cirinoi depends on how you grow it. If you have indoor plants, watering them every day is recommended. Take into consideration the size of your Anthurium Cirinoi, the bigger the size of your plants the more water it will need.

Watering outside plants should be done every two or three days depending on the climatic condition of your area. One way to know when to water your plant is by its moisture level in soil. When planted in a bog garden, the soil will be moist enough not to need watering. But when indoors, watering should be made daily.

Watering is achieved by simply tilting the pot, so that any excess water drains out. The combination of a dark-colored pot and regular watering will maintain a constant moisture level in your Anthurium Cirinoi’s soil bed. However, if the leaves are yellow and dropping off of your plant they are dead and should be discarded immediately.

What is the ideal temperature for Anthurium Cirinoi?

Anthurium Cirinoi prefers a temperature of between 65 and 76oF. However, the ideal temperature can vary depending on the plant size and age.

The ideal temperature refers to the temperature at which the plant’s leaves are most comfortable. This can be achieved by keeping your Anthurium Cirinoi in its own environment, or by placing it in a greenhouse or artificial light.

Anthurium Cirinoi grown outdoors will enjoy its optimum temperature during summer (April through to September). During this period, the surrounding soil will warm to around 80oF. Plants of all types should be exposed to sunlight to maintain a healthy red color.

During autumn (September through to March), temperature changes, with the open air temperature dropping an average of 30oF. During this period, Anthurium Cirinoi can be placed indoors in a room which has been heated. It is advisable to place them near windows which receive sunlight during this period and can also be protected from freezing temperatures with a frame or box surrounding them.

How do you propagate Anthurium Cirinoi?

Anthurium Cirinoi are very hardy plants and can be propagated vegetative by cuttings or seeds. Three to four young plants should be tied together to form a single clump in order to create a bigger plant. The best time to do this is during the summer (April through September). The following are procedure when propagating Anthurium Cirinoi by cutting;

  • Select a healthy plant. Look for healthy, green, growing plants and make short cuts (1/2 inch) down the stem with your pruning shear.
  • Cut four to six inches of stem from the base of the plant and train branches on a 6-inch nursery pot with drainage holes and keep at room temperature for two weeks before planting into the ground.
  • After two weeks, plant the cuttings in rich, loose, well-drained soil. Ensure the soil is well watered.
  • Water the pots using a fine rose spray to moisten the roots and keep in a shaded area when growing young plants.
  • When new growth appears on 1-inch stems, repot and water regularly.
  • Once a strong root system has been established, move to a larger pot. Prune the plant during the growing season to encourage new growth and flowering.
  • Remove and discard yellowing, dying leaves from the top of the plant.

How do you propagate Anthurium Cirinoi by seeds?

Anthurium Cirinoi are self-sterile plants and hence self-pollination is unreliable for producing seedlings. To produce reliable seedlings, you must use a second compatible species of an Anthurium. The following are procedure when propagating;

  • Select a healthy plant to be the seed parent and one or more plants to be the pollen parent(s). The pollen parents should be grown under exactly the same conditions as the seed parent plant. Select one plant of each sex in order to pollinate your entire group of plants.
  • To prevent self-pollination, you need to physically isolate them from each other.
  • To encourage cross-pollination, plant the partners in a multi-pot.
  • Fertilize both plants as usual.
  • In order for the seedlings to establish themselves and become healthy, give them supplemental lighting throughout the night. Be aware that most Anthurium seeds germinate very poorly in storage and should be planted after a few weeks of storage.
  • Once a strong root system has been established, move to a larger pot and periodically repot them for new growth and flowering.

How much humidity do Anthurium Cirinoi?

Anthurium Cirinoi prefer the humidity levels to be around 50% to 60%. This can be achieved by misting them daily, using a humidifier, or placing their pot next to a running water feature.

If you choose to place them near an open water feature, use one that is powered by electricity. The reason for this is that when placed near a running water feature with no filtration system, leaves may become discolored or damaged from minerals and dirt in the water. Anthurium will be able to enjoy this feature in their indoor home.

Anthurium Cirinoi should also be able to enjoy their home with a decent amount of sunlight. To enjoy the sun, either places them in a greenhouse or opens outdoor location and closes the leaves from direct sunlight so that the leaves can still stay healthy.

If you choose to place Anthurium Cirinoi near an open water feature, ensure that it is powered by electricity. The same applies to your open windows when placing Anthurium indoors.
