How to Propagate Anthurium Clarinervium

There are two methods you can choose from to propagate your plant: Anthurium clarinervium cuttings or root division. Below, we provided a step-by-step guide for each method so that you will know which one is easier to do for you:

Stem Cuttings

1. First of all, you need to obtain stem cuttings from your plant. It is better to cut from new growth or you can obtain the cuttings when you are pruning your plant. Make sure that the cuttings are at least two to four inches long with two leaves. Also, always cut above a leaf node.

2. After that, you can either do water propagation or cure the stem cutting before planting it:

Water Propagation

    • Place the cuttings in a jar filled with water until they produce roots that are at least one inch long

Curing the Stem

    • Curing allows the formation of a callous end to promote healthy growth. To cure your stem cutting, lay it in a warm room (not hot) for 5 to 7 days.

3. Plant the stem cutting in a self-draining pot. Keep the soil moist until your plant starts growing and make sure that it gets enough lighting. Follow the plant care tips we have mentioned in the last section of this blog.

Root Division

  1. Carefully pull your Anthurium out of the soil on its pot to avoid damaging its roots.
  2. Rinse the roots to remove the soil using gentle running water.
  3. Once the roots are clean, gently pull some roots apart to divide the plant.
  4. Allow the divided roots to dry for at least 12 hours by laying them on a clean paper towel.
  5. After the roots have dried, plant them using the recommended potting soil. Make sure the roots are fully immersed in the soil.

Common Anthurium Clarinervium Diseases/Problems

The plant is easy to grow. But because of its specific potting and humidity requirements, it can be affected by various diseases if not cared for correctly. Below are the common problems that you might encounter with Anthurium Clarinervium plants:

#1 Root Rot

  • Possible causes might be overwatering and humid conditions
  • Use a well-draining potting mix to avoid root rot
  • Try to trim off diseased roots and repot your plant
  • You can also propagate the remaining healthy roots to save your plant if the root rot is worse than expected

#2 Pest Infestation

  • Since the plant needs high humidity to live, it attracts pests like spider mites, mealybugs, scale, and aphids
  • Spray your plant with insecticidal soap to control the pests

#3 Yellow Leaves

  • The common causes are overwatering, root rot, and not enough sunlight
  • Other symptoms include droopy plant stems
  • Control your watering schedule and place your plant in a bright location

#4 Brown Leaf Edges

  • Common causes are lack of humidity and too much direct sunlight which leads to leaf scorch
  • The only solution is to add humidity through regular misting or using a humidifier (we will discuss more on this in the Anthurium clarinervium plant care tips section)

#5 Stopped Growing

  • Your plant will grow slowly and look like it stopped growing if it is not receiving enough light and its environment is dry
  • Move your Anthurium to a brighter location (do not expose your plant under direct sunlight)
  • Daily misting and putting the pot on a pebble tray can also help increase humidity

#6 Dull Foliage

  • Again, not enough light can cause your plant to have dull veins and leaves. Without enough light, your plant cannot undergo the photosynthesis process to produce its needed nutrition
  • Follow the recommended lighting tips in the next section to fix a dull Anthurium foliage

Anthurium Clarinervium Plant Care Tips

When you are growing a tropical plant as a houseplant, you have to mimic its natural habitat so it can thrive the way you want it to. As we’ve said earlier, Anthurium clarinervium is a very sensitive plant with special living requirements. If you want your plant to grow healthy, follow the tips we provided below:

Soil

Let’s start with the Anthurium clarinervium potting mix. First of all, the soil must be well-draining because this plant needs quick drainage to avoid root rot. You can check if the soil mix is well-draining beforehand. Just pour water on it while it is in the pot and observe how fast the water is draining through it.

For the recommended potting mix, orchid bark soil mixes would be the best. The key ingredients for this potting mix recipe are sphagnum moss, perlite, and Douglas fir bark. However, make sure that there is more sphagnum moss and perlite compared to the bark. The ideal ratio is 5:1. Lastly, the acidity of the soil should range from 5.5 pH to 6.5 pH.

Lighting

For Anthurium clarinervium lighting, here are the tips you can follow:

  • The plant thrives in medium-light conditions
  • Avoid direct sunlight because it can scorch and burn your plant. The plant has a high sensitivity to heat and the sun.
  • Stick to east or north-facing windows and avoid west or south-facing windows

Watering

Remember that Anthurium clarinervium roots are exposed because they are epiphyte plants. The exposed roots will dry out faster compared to other plant roots, especially during warm seasons. It is better to water your plant around three times per week during these times.

However, do not overwater your plant as it can lead to root rot and cause your plant to die. Only water your plant if the first two soil layers are dry. Always make sure that you use a self-draining pot for your plant too.

Moreover, keep the soil moist during the growing season (March to September). You don’t have to water the plant that much in the dormant seasons and in colder months because the soil can retain water easier in these times. Only water your plant two times a month during the dormant seasons.

Temperature

The plant has different temperature requirements depending on the season. In the growing season, the ideal temperature range for optimal growth is between 64°F (18°C) and 70°F (21°C). The plant can also tolerate temperature ranges from 54°F (12°C) to 85°F (29°C).

Humidity

These plants thrive and grow faster in very humid conditions. Their leaves will also become greener and brighter in high humidity. The optimal humidity is around 80% but 60% is good enough.

There are two ways you can do to increase humidity in the plant’s environment:

  • Use a humidifier
  • Use a pebble tray

If you don’t have enough budget, you can use create a pebble tray for your plant:

  • Fill the tray with pebbles
  • Add water but do not add too much that the water is already covering the pebbles
  • Place your plant’s pot on the pebble tray

The water evaporating from the pebble tray will create humidity that will go straight to the plant.

Fertilizing

Use half-strength Anthurium clarinervium fertilizer with a high phosphorus content. The phosphorus should have the highest amount compared to all other elements in the fertilizer. This plant doesn’t need to be fertilized often. You only need to fertilize it every two months in its growing season and once a month in the winter months.

Moreover, you need to flush the soil of your plant every three to four months to prevent the buildup of mineral salt. This is a common issue with Anthurium clarinervium plants. To flush the soil, you just need to run water through it for at least three minutes.

Repotting

Repotting Anthurium clarinervium plants is as easy as repotting any other houseplant. These plants have a slow growth rate. Thus, you only need to repot them every two to three years, especially if they are already outgrowing their current pot. Also, the best time to report is during springtime.

In ideal living conditions, your plant can grow quickly and develop strong stems as well as broad leaves. So it is recommended to check your plant regularly to make sure that its pot still has enough space to make room for new growth. Or else, your plant might become stunted.

Here are the signs that can tell you if it’s time to repot your plant:

  • If your plant is already too big for its pot
  • If you can see roots in the pot’s topsoil
  • If the plant’s roots are growing outside the pot’s drainage holes

Pruning

Occasional pruning encourages vigorous growth and helps in improving your plant’s appearance. You can snip off dead, diseased, or faded foliage, as well as leggy stems, every once in a while to help your plant grow better. We recommend pruning your plant in the spring before its growing season. Also, since the flowers are not aesthetically appealing, Anthurium clarinervium flower cutting is recommended to allow your plant to concentrate on producing new growth.
