Amorphophallus konjac (Voodoo plant)
 
Description
Amorphophallus konjac, commonly known as the Voodoo plant, is a fascinating and unique tuberous plant native to Southeast Asia. It is well-known for its striking foliage and unusual flowering structure. The single leaf is umbrella-shaped, deeply divided, and can reach impressive sizes. When mature, the plant produces a dramatic inflorescence—a large spadix surrounded by a maroon spathe—which emits a distinctive odor to attract pollinators.
Konjac is prized for its ornamental value and is also cultivated for its edible corms, which are used in traditional Asian cuisine to make konjac jelly or noodles.
 
Care Sheet for Amorphophallus konjac
Light
🌞 Bright, indirect light is ideal. It can tolerate some morning sunlight but should be shielded from intense afternoon sun.
During dormancy, light is unnecessary as the bulb rests.
Temperature
🏡 Thrives in temperatures between 20–30°C (68–86°F) during the growing season.
Protect the bulb from frost by overwintering it indoors if temperatures drop below 10°C (50°F).
 
Watering
During the growing season (spring to autumn), water regularly to keep the soil slightly moist but not soggy.
Allow the topsoil to dry slightly between waterings to prevent root rot.
When the plant enters dormancy (late autumn), stop watering entirely and store the bulb in a dry, cool place.
 
Soil
Use a well-draining soil mix, such as equal parts loam, sand, and compost. Amorphophallus konjac prefers nutrient-rich soil.
Ensure the container has drainage holes to avoid waterlogging.
 
Feeding
Apply a balanced liquid fertilizer every 2–4 weeks during the active growing season.
Stop feeding once the plant starts to die back in preparation for dormancy.
Dormancy
After the foliage dies back, the plant enters a dormant phase.
Remove the bulb from the soil, clean it, and store it in a dry, dark, and cool environment until spring.
 
Potting/Repotting
Repot the bulb annually in early spring, just before it begins to sprout.
Plant the bulb with the top just below the soil surface. Larger bulbs may need deeper pots.
 
Pests and Diseases
Generally pest-free but may occasionally attract fungus gnats or suffer from root rot if overwatered.
Inspect regularly and maintain proper watering to avoid issues.
 
Special Notes
The inflorescence has a strong odor, often compared to rotting meat, but this only lasts for a few days.
Handle the bulb with care, as it can cause skin irritation. Wear gloves if necessary.
 
With proper care, Amorphophallus konjac will reward you with its extraordinary growth and fascinating lifecycle!
