Why Herbs Fail in Mason Jars: Drainage Myth and Light Needs

A novice planted chives, cilantro, basil (seeds), and oregano (starter) in mason jars with gravel "drainage." After moving to a windowsill, oregano wilted with black spots within hours. Soil damp, house 70°F.

Mason Jars Are Poor Seed-Starting Containers

Leroy explains: Gravel doesn't create drainage—water saturates the soil above it, creating a perched water table that promotes rot and fungus. Jars also lack airflow.

Basil's Specific Needs

Basil requires bottom heat and full morning sun to thrive—conditions hard to meet in a jar on a windowsill.

Better Approach

• Use pots with drainage holes.
• Provide strong light and warmth.
• Water only when surface is dry.
