Overview of Amorphophallus zenkeri subsp. zenkeri

How to Grow

Choosing a Location 🌞

Amorphophallus zenkeri subsp. zenkeri thrives in partial shade to filtered sunlight. Aim for warm conditions, ideally between 20°C to 30°C (68°F to 86°F), and ensure high humidity levels above 60% for optimal growth.

Soil Preparation 🌱

For soil preparation, use a well-draining mix rich in organic matter, such as peat or compost. The ideal soil pH should be slightly acidic to neutral, ranging from 6.0 to 7.0.

Planting Techniques 🌿

When planting, corms should be placed 4-6 inches deep in the soil. Space them 12-18 inches apart to give each plant room to grow and flourish.
