Can I save a plant with root rot?

Yes, if you catch it early. Trim the dead roots and repot in dry soil.

How often should I water to avoid this?

Aim for every 7 to 14 days, but always check the soil moisture first rather than following a strict calendar.

Corn Plant: root rot, causes and fixes

Check these first

Stick your finger two inches into the soil to check for dampness.
Lift the pot to see if water is trapped in the saucer.
Gently pull the plant from the pot to inspect the roots for a foul smell or dark color.

Likely causes

Overwatering
Most likely
How to tell: The soil feels soggy and does not dry out between waterings. The base of the stem may feel soft or squishy to the touch.
What to do: Stop watering immediately and let the soil dry out. If the rot is severe, you must repot the plant into fresh, well draining soil and trim away any black, mushy roots.
Poor drainage
Possible
How to tell: Water sits in the bottom of the decorative pot or the saucer. The plant looks wilted even though the soil is wet.
What to do: Ensure your pot has drainage holes at the bottom. Empty the saucer after every watering so the roots never sit in standing water.
