Houseplant Guttation: Why Your Corn Plant "Cries"

Natural Water Release

Water droplets on leaf tips of dracaena (corn plant) and other tropicals indicate guttation—not "crying." When roots absorb more water than the plant can transpire (usually at night with high soil moisture and humidity), root pressure forces water out through specialized leaf pores (hydathodes).

Key Characteristics

• Pure water—not sticky
• Occurs on leaf margins/tips
• Common in grassy tropicals (dracaena, dieffenbachia, philodendron)
• Indicates ample soil moisture

When to Worry

If droplets are sticky, that's honeydew from aphids, scale, or mealybugs—not guttation. Treat with insecticidal soap.

Management

Reduce watering frequency, improve air circulation, ensure pots drain freely. Guttation itself is harmless but signals conditions that could promote root rot.
