Everything it needs
9 essentials at a glance
Watering
Rafflesia arnoldii requires consistent moisture, but it is crucial to avoid waterlogging.
Water the plant every 2-3 days during the growing season, ensuring the soil remains damp but not soggy. In the dormant season, reduce watering to once a week. Signs of over-watering include yellowing leaves and root rot, while under-watering can cause wilting and browning of the edges of the leaves.
Light
This plant thrives in partial shade, mimicking its natural habitat in the rainforest understory.
Ideally, it should receive 4-6 hours of filtered sunlight daily. Direct sunlight can scorch the leaves, while too little light can hinder growth and flowering.
Soil
Rafflesia arnoldii prefers well-draining, rich organic soil with a pH range of 5.5 to 6.5.
A potting mix that includes peat moss, compost, and perlite is recommended to ensure proper drainage and nutrient availability.
Humidity
The Stinking Corpse Lily thrives in high humidity levels of around 70-90%.
To increase humidity, consider using a humidity tray or a humidifier. If humidity is too low, the plant may exhibit wilting leaves and brown tips.
Temperature
Ideal temperatures for Rafflesia arnoldii range from 75-85°F (24-29°C) during the day and 60-70°F (15-21°C) at night.
It is sensitive to cold and should be kept in hardiness zones 10-11. Prolonged exposure to temperatures below 50°F (10°C) can be detrimental.
Fertilizing
Use a balanced, slow-release fertilizer with an NPK ratio of 10-10-10 during the growing season.
Fertilize every 4-6 weeks, tapering off in the fall. Signs of nutrient deficiency include stunted growth and yellowing leaves.
Pruning
Pruning is minimal for Rafflesia arnoldii.
Remove any dead or yellowing leaves to promote healthy growth. Use clean, sharp scissors or pruning shears to avoid damaging the plant. Deadheading is not applicable as the plant produces a single flower.
Repotting
Repot Rafflesia arnoldii every 2-3 years or when the roots outgrow the pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter and follow these steps: gently remove the plant from its pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Propagation of Rafflesia arnoldii is challenging and typically occurs through seed germination.
Collect seeds after the flower has bloomed and allowed to mature. Sow seeds in a well-draining medium and keep them moist. Germination can take several months, and the best time to propagate is during the rainy season.
When it's unhappy
Yellowing leaves
Why it happens
Often caused by over-watering or nutrient deficiency.
How to fix it
Check soil moisture levels and adjust watering frequency. Consider fertilizing if nutrient deficiency is suspected.
Wilting leaves
Why it happens
Typically a result of under-watering or low humidity.
How to fix it
Increase watering frequency and ensure the humidity levels are adequate.
Root rot
Why it happens
Caused by waterlogged soil and poor drainage.
How to fix it
Ensure proper drainage in the pot and reduce watering frequency. Remove affected roots and repot in fresh soil.
Flower drop
Why it happens
Can occur due to stress from temperature fluctuations or inadequate light.
How to fix it
Maintain stable temperatures and ensure the plant receives the right amount of filtered light.
Brown leaf tips
Why it happens
Often a sign of low humidity or over-fertilization.
How to fix it
Increase humidity levels and reduce fertilizer application.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to grow. Ensure it receives adequate light and humidity to encourage blooming.
Summer
During summer, maintain consistent moisture and humidity levels. Fertilize every 4-6 weeks to support growth and flowering.
Fall
In fall, gradually reduce watering as the plant enters dormancy. Monitor humidity levels to prevent stress as temperatures drop.
Winter
In winter, limit watering to once a week and ensure the plant is kept in a warm environment. Avoid fertilizing during this dormant period.
Toxicity & Safety
Rafflesia arnoldii is not known to be toxic to pets or children. However, ingestion of any part of the plant can cause gastrointestinal discomfort, so it is best to keep it out of reach.
