How often should I water to avoid rot?

Water every 7 to 14 days, but always check the medium first. If it still feels damp, wait a few more days.

Can I save a plant with root rot?

Yes, if you catch it early. Trim the dead roots, improve the drainage, and keep the plant in a bright spot with good airflow.

Staghorn fern: root rot, causes and fixes

Check these first

Smell the potting medium for a sour or rotten odor.
Check if the roots feel soft and mushy rather than firm.
Ensure the plant is not sitting in standing water.

Likely causes

Overwatering
Most likely
How to tell: The plant looks wilted even when the medium is wet. The roots will appear dark, slimy, and smell unpleasant.
What to do: Remove the plant from its mount or pot and trim away any black, mushy roots. Repot the fern in fresh, well draining sphagnum moss and reduce your watering frequency.
Poor Drainage
Possible
How to tell: Water pools at the bottom of the container or the mounting material stays soaked for weeks. The base of the plant may start to turn black.
What to do: Ensure your mount or pot has plenty of holes for air circulation. Use a chunky, airy mix like bark and moss to prevent water from stagnating.

When to worry

If the base of the plant is turning black and mushy, the rot may be too advanced to save. Act immediately if you notice a foul smell or dark, soft roots.

Stopping it coming back

Always allow the medium to dry out significantly between waterings and ensure excellent airflow around the roots.
