Propagating Geogenanthus Ciliatus

Envy Tropicals By MV

To propagate a Geogenanthus ciliatus, stem cuttings are the most effective method, preferably during the spring when the plant is in its active growth phase. Select a healthy stem (4-6 inches long) with one or two leaves, making a clean cut just below a leaf node.

Let the cutting dry for a day or two, and then plant it in a well-draining potting mix. Water well and ensure it gets bright and indirect light. Keep it safe from direct sun exposure during this time. The cutting will form roots in 4-6 weeks.

Best Pot Size for Growing Geogenanthus ciliatus

You can start Geogenanthus ciliatus in a 5-6 inches pot, which will be good for a few years, depending on its growth and spread, keep on repotting it into a size bigger container than the old one.

Requirements for Growing Geogenanthus ciliatus

The optimal light for Geogenanthus ciliatus is filtered sunlight, providing bright yet indirect illumination. While they can tolerate low-light areas for a period, geo plants require some bright light over time to promote healthy leaf growth.

Direct sunlight should be avoided as it can scorch the delicate leaves. If relocation is not possible, using a light cloth or curtain to filter the sunlight or using growth lights in low-light areas can be beneficial.


For optimal growth of Geogenanthus ciliatus, use a well-draining soil mix that retains moisture. Maintain a slightly acidic to neutral pH level, around 6.5 to 7.

Here is How to Check Your Soil pH at Home

Add perlite, peat moss, coco coir, or orchid bark to the potting mix for ideal conditions. Ensure the pot has proper drainage holes to allow for easy water flow.


Geogenanthus ciliatus hates overwatering. In general, water the plant when the top inch (2.5 cm) of soil feels slightly dry to the touch. This may require watering approximately once or twice a week during warmer months.

Temperature and Humidity

The ideal temperature range for Geogenanthus ciliatus is around 65-75°F (18-24°C). This temperature range provides optimal conditions for growth and overall health.

Geogenanthus ciliatus thrives in environments with moderate to high humidity levels, typically ranging from 50% to 70%. Here are some ways to increase humidity indoors:

  • Place a humidifier near the plant or use a room humidifier to add moisture to the air.
  • Grouping plants together can create a microclimate of increased humidity.
  • Set the plant on a tray or saucer filled with water and pebbles. As the water evaporates, it increases the humidity around the plant. Ensure that the plant’s roots do not sit directly in the water to avoid waterlogging.
  • Mist the plant’s foliage with water using a spray bottle. Mist the leaves regularly, especially during drier periods.

Use a balanced, water-soluble fertilizer like 20-20-20 or similar. Dilute it to half or quarter strength to avoid overfertilizing, as this can lead to salt buildup in the soil and cause damage to the plant.

Fertilize Geogenanthus ciliatus every 5-6 weeks during the growing season, which typically spans from spring to early fall. Reduce or suspend fertilization during the winter months when the plant’s growth slows down.

Pests and Diseases

Geogenanthus Ciliatus is prone to infestations by common indoor houseplant pests like mealybugs, thrips, and spider mites. It is important to regularly check the plant for any signs of pests or diseases. If an infestation is detected, isolate the affected plant and treat it with suitable pesticides like neem oil or insecticidal soap.

Due to its preference for high humidity and consistent moisture, Geogenanthus ciliatus can be susceptible to fungal diseases. If you notice any signs of disease, promptly isolate the affected plant and treat it with a suitable fungicide.
