1. Diffused Sunlight and Suitable Location

Anthurium Rotundistigmatum naturally grows on the Panama forest beds around 500-1000 meters, covered by tall trees. Therefore, you should care to provide a similar setting at home.

Ensure to keep Anthurium Rotundistigmatum in diffused sunlight, such as a shady spot a few feet away from the window, door, or patio.

Houseplants thrive best in indirect sunlight

Pay special attention to its location as the direct sunlight can burn the leaves, and a drafty, low-lit place will slow down its growth.

However, optimal sunlight is a must to attain deep green leaves.

Note: About 75-80% or at least 6-8 hours of indirect sunlight would suffice to keep the plant looking green.

Tips to Provide Adequate Sunlight

  • Find a well-lit spot with adequate indirect sunlight: patio, door, and window that gets some early morning sun.
  • The east-facing window will be an ideal spot as it receives ample early morning sunlight.
  • Alternatively, place them close to the north-facing or west-facing window.
  • Ensure to keep them 5-6 feet away when placed at the south-facing window to avoid direct sunlight.
  • Rotate your plant every few weeks at the same spot to ensure even growth on each side.
  • Consider placing the plant under appropriate LED grow light when the sunlight seems scarce or insufficient, especially in fall and winter.

Light color spectrum and intensity play an essential role in a plant’s growth. Read our article about the best color light for plant growth?

2. Regular Watering

Anthurium Rotundistigmatum enjoys evenly moist soil, but it does not tolerate sitting in a pool of water.

The basic rule of watering your Anthurium is to wait until 70% of the topsoil or top two inches to dry out.

Provide 300-500 ml water every 4-5 days to let the soil dry out between watering to Anthurium Rotundistigmatum. Otherwise, water once every week with 700-800ml water.

Water the plant when required.

This watering schedule would only apply in the growing season (spring and summer). Cut back on watering in fall and winter to once every 15 days.

Anthurium Rotundistigmatum can slightly tolerate drought conditions significantly when the temperature exceeds 95 degrees Fahrenheit.

However, an extended dry period will cause excess transpiration (water loss) and slow down its growth.

Overwatered PlantUnderwatered Plant
Yellowing, limping, and droopy foliageWilted and crispy leaves
Decayed lower rootsBrown leaf edges
Slowed plant growthCurled and browned leaves
Root RotStunted foliage growth

Tips to Provide Adequate Watering

  • Inspect whether the top 25% of soil or about 2-inches of the topsoil is dry.
  • Use a soil moisture meter or insert your finger to inspect the soil condition
  • Immediately water the plant if it seems dry; otherwise, wait for a few more days.
  • Run the container under the tap and let it sit until all the water comes out of the drainage holes.
  • Cut back on watering when you catch overwatered symptoms, including brown soil, decayed stems, and mushy roots until it revives.
  • For severely dehydrated Anthurium, deepwater the plant to moisten the soil or place it on a pebble tray filled with cool water.
  • Whenever watering, care to use distilled or rainwater water kept at room temperature to avoid chemical build-up in the soil.

3. Ideally Warm Temperature

Anthurium Rotundistigmatum thrives well in USDA hardiness zones ten or above. They enjoy ideally warm and humid conditions around the year as it mimics the natural Panama lowlands.

Ensure to keep the temperature anywhere from 68°F to 79°F (20°C to 26°C) during the day and nothing less than 60°F at night for Anthurium Rotundistigmatum.

When you notice droopy leaves and stems, you should know it is too cold, and dried, crispy leaves mean it is overly hot.

Although it can survive well up to 90°F, especially in summer, prolonged drought can push back the plant growth.

Tips to Ensure Optimally Warm Temperature

  • Keep your Anthurium close to the window where it receives a lot of filtered, diffused sunlight.
  • Mist the plant leaves to increase humidity when the temperature rises above 90°F.
  • Move them inside under LED grow light when the temperature drops below 60°F.
  • Consider covering the plant with a frost blanket or plastic bag to prevent cold drafts in winter.
  • Otherwise, placing a heating pad under the plant will help keep the soil temperature optimal.

Pro Tip: Avoid placing your Anthurium in front of the heater or air conditioner to avoid extreme temperatures.

4. Highly Humid Condition

Anthurium Rotundistigmatum prefers slightly high humid levels to maintain upright stems, even growth, and rich green leaves.

Provide about 70% humidity to Anthurium Rotundistigmatum that would naturally mimic wet tropical forests.

When the humidity level drops, the plant growth will simultaneously slow down. A low humid condition is a significant concern for Anthurium plants as they quickly lose water from their leaves.

On the other hand, too much humidity can invite diseases and fungus to the plant. Here is an image highlighting the low and high humid conditions.

Tip to Maintain High Humid Condition

  • Huddle all the plants together in a room to naturally boost the humidity level.
  • Alternatively, add an electric humidifier to increase or decrease the humidity level.
  • Misting the leaves occasionally in summer will help increase humidity in the air.
  • Otherwise, place your plant on a pebble tray filled with water to keep the soil cool and moist.

However, beware of extreme humid conditions as Anthurium are susceptible to bacterial and fungal infestations.

One way to avoid the onset of the disease is to inspect the plant regularly and quarantine it.

5. Fast Draining, Organic Soil Mix

Anthurium Rotundistigmatum ideally enjoys an organic soil mix that drains quickly to avoid excessively wet soil.

The advantage of such a mix is that your plant will retain enough moisture before the soil dries out.

Provide an organic potting mix based on perlite, peat moss, and regular potting soil to keep the mix well-aerated.

Adding some coco coir and orchid bark will help retain moisture for a prolonged duration. One way to obtain an ideal potting mix is to get a commercial mix from the market.

Here are a few recommendations;

Soil Mix Image Features
Black Gold All Purpose SoilA multi purpose, nutrient rich mix that's ideal for most of the plants
Miracle-Gro Indoor Potting MixContains coco coir, which holds and releases water,
Also helps soil to get easily wet again
FoxFarm Ocean Forest Potting Mix Ocean Forest has a light, aerated texture that's perfect for indoor and outdoor plants

However, commercial mixes usually contain more soil, retaining more water and later compaction.

Hence, the best solution is to prepare a homemade mix, and here is how to do it.

  • Add one part of perlite with the same part of peat moss and potting soil
  • Mix half part coco coir and orchid bark

Alternatively,

  • Mix two parts of orchid mix with one part of activated charcoal and a mix of perlite and peat.

6. Monthly Fertilization

Anthurium enjoys regular fertilization in the growing season, but you must remember how to apply the fertilizer best.

Provide mild plant food rich in phosphorus to Anthurium Rotundistigmatum once a month or dilute the solution to 1/4 strength before applying.

Keep the fertilization to the active growing season, spring and summer, and immediately cut back in fall and winter as the plant goes into dormancy.

Furthermore, you must remember that Anthuriums do not withstand too much potassium but love phosphorus to grow flowers and fruits.

An overfertilized Anthurium will begin exhibiting changes such as yellowing and drooping foliage, stunted growth, and burned vegetation.

On the other hand, the plant not receiving enough Nitrogen and phosphorus will mainly indicate yellowing leaves, dropping blossoms, and a sick-looking plant.

Tips to Fertilize Anthurium Rotundistigmatum Properly

  • Use plant foods rich in Phosphorus and Nitrogen than Potassium.
  • Choose a slow-release granular fertilizer or liquid-based plant food.
  • Ensure to dilute the solution to 1/4 strength by mixing in water using the liquid-based fertilizer to prevent burns and salt residue.
  • Moisture aids in nutrient uptake. So, I recommend watering the plant before fertilizing it.
  • You can remove excess salts from the pot by soaking it in lukewarm water.

Here are a few recommendations;

Pro Tip: Organic fertilizers work great, too, including eggshells, chicken/fishbone, or vegetable leftovers.

7. Growth Rate and Pruning

Anthurium Rotundistigmatum is your typical tropical sub-plant with lush green leaves that become larger than the plant.

A member of Belolonchium, it boasts thin, ovate-triangular leaves that spread 26-56 cm long and 17-30 cm wide.

It is broadest at the point of petiole attachment with the anterior lobe.

The upper surface may turn from matte to semi-glossy, depending on the time of the year.

Like most Anthurium, it blossoms every year in late spring or summer, where you would notice a pale green to reddish-purple spathe.

It usually turns reddish brown with time, and the size varies from 8 to 13.5 cm long.

The Anthurium will give out beautiful berry-like fruit about 25 cm long in an obvoid, rounded shape if you are lucky.

However, Anthurium Rotundistigmatum does not require frequent pruning except for dead, decayed, and old leaves.

8. Repotting Anthurium Rotundistigmatum

Anthurium Rotundistigmatum would only require repotting every couple of years to retain upright shape and timely root growth.

They are slow-to-moderately growing plant that need repotting once every two years.

Check for visible signs of slowed growth or roots growing out of the drainage holes to consider repotting.

Propagating Anthurium Rotundistigmatum

Luckily, you can propagate Anthurium Rotundistigmatum quickly at home. Moreover, you can multiply this beautiful plant using healthy stem cutting or plantlets.

Propagating via seeds is also possible, but you must ensure to get berries from the fruiting after pollination and plant them in a germination tray like growing any other seedling.

Here are two popular ways to propagate Anthurium Rotundistigmatum.

1. Propagation via Stem Cuttings

Propagating the stem-cutting is the easiest way to go with Anthurium.

In early spring, you need to obtain healthy stem cutting to begin the propagation process.

Here is how to go ahead with it.

  • Inspect your plant for healthy stem cuttings. An upright stem with one to two large leaves would suffice.
  • If you notice aerial coming from the bottom node, select it for the high chances of propagation.
  • Take a sharp knife or pruning shear to cut the stem below the bottom node.
  • Ensure the freshly cut stem has at least two nodes and one leaf attached.
  • Take a glass of water set at room temperature and add some rooting hormone dropping.

  • Next, insert the cutting into the glass and keep it in a warm location.
  • Change the water every five days to avoid fungal or bacterial growth.
  • Alternatively, take a small pot and the potting mix to propagate directly in the soil.
  • Before transplanting the stem cutting, apply some rooting hormone to the cut end.
  • Immerse the cutting into the soil with leaves staying outside, moisten it, and leave the cutting in a warm location.
  • Cover the cutting with a clear plastic bag to encourage high humidity and warm condition.

Voila! Your stem cuttings will begin growing new feeder roots within a few weeks.

2. Propagation via Plantlets

  • Rooting plantlets is another way to go with propagating Anthurium Rotundistigmatum unless it is a relatively new plant.
  • The plantlets are attached to the mother plant’s stem that you can easily cut off for propagation.
  • Take a pruning shear and cut the plantlet from the mother plant without damaging the main stem.
  • Next, prepare a potting mix in a new pot.
  • Trim the plantlet off any yellowing, rotting, or damaged sections.
  • Nicely place the plantlet in the potting mix and provide a similar growing condition to witness a healthy growth within a few weeks.
