Overwatering Causes Brown Spots on Indoor Plants

Diagnosing Brown Spots: The Overwatering Connection

A plant owner waters three unidentified indoor plants three times weekly, resulting in brown spots on leaves including new growth.

Immediate Diagnosis

Watering three times weekly is excessive for almost all houseplants. Brown spots on new growth particularly indicate root stress from waterlogged soil.

Correct Watering Protocol

• Most plants: Allow top 1-2 inches of soil to dry between waterings
• Succulents/cacti: Allow soil to dry completely
• Moisture-lovers (ferns, peace lilies): Water when surface feels dry
• Never water on a schedule - Check each plant individually

Next Steps

1. Identify your three plant species for specific care
2. Immediately reduce watering frequency
3. Check for root rot (mushy, dark roots)
4. Repot in well-draining mix if soil stays soggy
5. Remove severely damaged leaves

The owner was asked to provide plant names for tailored advice. Proper identification is essential since water needs vary dramatically among species.
