How to Grow Amorphophallus Rivieri

Locate a plant pot that is twice the width of the Amorphophallus rivieri corm. the name of the root system. Fill the pot with standard potting soil until it reaches approximately 1 1/2 inches from the top rim.

Measure the width of the corm with a ruler and dig a hole in the center of the potting soil that is the same depth. Insert the corm into the hole horizontally and cover it up with potting soil.

Water the soil until it drains from the bottom of the pot. Then monitor the soil moisture daily and add more when need to prevent it from drying. The soil must always feel damp but not wet.

Place the pot in an area that has full sun exposure or partial sun exposure. If outdoor temperatures are above 60, you can place it outdoors, otherwise find an indoor window.

Fertilize the soil once the top of a leaf emerges from it. Apply an all-purpose plant fertilizer monthly from spring through the midsummer, using the amount of product specified on the packaging. In the midsummer switch to a fertilizer labeled as “bloom booster” until the plant dies back in the fall.

Wait until the leaves die back in the fall, cut them off 2 to 3 inches above the surface of the soil using hand pruners. Stop watering the soil until the central flower dies back as well. Allow the plant to remain dormant until spring and then resume watering.
