How to Prevent Orchid Root Rot

Published on August 02, 2025 | By Orchidshade

Orchid root rot is a common issue that can devastate your beautiful plants, especially in humid climates like Dhaka’s. Caused by overwatering, poor drainage, or fungal growth, root rot turns healthy roots into mushy, brown messes, stunting growth and potentially killing your orchid. At Orchidshade.com, we’re here to help you prevent this problem with practical tips tailored for orchid lovers. Let’s dive into how to keep your orchids thriving!

What Causes Orchid Root Rot?

Root rot occurs when orchid roots sit in water for too long, depriving them of oxygen. In humid environments, fungi like Pythium or Rhizoctonia thrive, attacking weakened roots. Common culprits include:

Overwatering or using heavy soil instead of proper orchid media.
Pots without drainage holes or saucers holding standing water.
Poor air circulation in damp conditions.

Steps to Prevent Orchid Root Rot

Use the Right Potting Media
Orchids need a well-draining mix like bark, coconut husk, or perlite. Avoid regular potting soil, which retains too much moisture. Repot every 1–2 years to refresh the media.
Choose Pots with Drainage
Opt for pots with holes to let excess water escape. If using decorative containers, ensure an inner pot with drainage sits inside.
Water Wisely
Water your orchids once every 5–7 days, allowing roots to dry out between sessions. In Dhaka’s monsoon season, reduce frequency and use rainwater to avoid mineral buildup.
Improve Air Circulation
Place your orchids in a breezy spot or use a small fan. Good airflow prevents moisture buildup, especially in humid weather.
Check Roots Regularly
Inspect roots monthly. Healthy roots are firm and green or white; rotten ones are soft and brown. Trim affected areas with sterile scissors and repot immediately.

Monsoon (June–September): Protect from heavy rain and ensure drainage.
