Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.

😖 Common Issues

Overwatering is a likely cause of issues with Rauh's Armatocereus. These plants are very sensitive to wet soil so if you notice your plant becoming squishy or translucent, overwatering is the likely culprit.

Cut your plant just past where the rot ends and allow it to callus over for a few days before replanting it in fresh, dry soil. Download Greg to make sure your plant never gets overwatered again!
