Everything it needs
9 essentials at a glance
Watering
Dischidia Nummularia prefers to dry out slightly between waterings.
Water thoroughly when the top 1-2 inches of soil feel dry, typically every 1-2 weeks. In the growing season (spring and summer), increase frequency, while in fall and winter, reduce watering. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaves to shrivel and drop.
Light
This plant thrives in bright, indirect light but can tolerate partial shade.
Ideally, it should receive 6-8 hours of filtered sunlight daily. Direct sunlight can scorch the leaves, so placing it near a window with sheer curtains is beneficial.
Soil
Dischidia Nummularia prefers a well-draining potting mix, ideally a blend of orchid bark, perlite, and peat.
The pH should be slightly acidic to neutral, around 6.0-7.0. Ensure the pot has drainage holes to prevent water retention.
Humidity
This plant enjoys high humidity levels, ideally between 60-80%.
To increase humidity, consider using a humidity tray or a humidifier. Signs of humidity stress include browning leaf tips and wilting leaves.
Temperature
Dischidia Nummularia thrives in temperatures between 65-85°F (18-29°C).
It is not frost-tolerant and should be protected from temperatures below 50°F (10°C). It can be grown in USDA hardiness zones 10-12.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20, diluted to half strength.
Fertilize every 4-6 weeks during the growing season and reduce frequency in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Dischidia Nummularia in spring to maintain its shape and remove any dead or damaged leaves.
Use clean, sharp scissors to make clean cuts. Deadheading is not necessary, but trimming back leggy growth can encourage bushier growth.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Carefully remove the plant from its pot, trim any damaged roots, and place it in fresh potting mix.
Propagation
Propagation can be done through stem cuttings.
Take a cutting with at least one node and place it in water or moist soil. Ensure it receives bright, indirect light and maintain humidity. Roots should develop in 2-4 weeks. The best time to propagate is during the growing season in spring or early summer.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or insufficient light.
How to fix it
Adjust watering frequency and ensure the plant is receiving adequate light.
Shriveling leaves
Why it happens
Under-watering or low humidity levels can lead to shriveling.
How to fix it
Increase watering frequency and humidity levels to restore plant health.
Leaf drop
Why it happens
Sudden changes in temperature or over-watering can cause leaves to drop.
How to fix it
Maintain stable temperatures and adjust watering practices.
Root rot
Why it happens
Over-watering and poor drainage can lead to root rot.
How to fix it
Ensure proper drainage and allow the soil to dry out between waterings.
Pest infestations (e.g., mealybugs)
Why it happens
Pests can thrive in high humidity and poor air circulation.
How to fix it
Regularly inspect the plant and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks with a balanced fertilizer.
Summer
During summer, maintain consistent moisture and humidity. Ensure the plant is not exposed to direct sunlight, which can cause leaf burn.
Fall
In fall, gradually reduce watering as the plant's growth slows. Monitor for pests, as they may become more active during this time.
Winter
In winter, reduce watering further and avoid fertilizing. Keep the plant in a warm area, away from drafts and cold temperatures.
