Growing Sensitive Plant (Mimosa pudica) from Seed Indoors

A Connecticut grower starts Mimosa pudica seedlings in November (40°F outside) under grow lights. Past attempts failed due to watering issues (likely overwatering/rot). Asks about watering frequency, light, and longevity.

Care Guidelines

• Tropical: needs >60°F. Keep indoors.
• Prefers sunny windowsill; fluorescent lights okay. Incandescent lights too hot.
• Small pots (2–3") for seedlings; larger pots cause slow growth and rot risk.
• Water when soil surface is dry. Frequency depends on conditions.
• Pinch/prune regularly to encourage branching and prevent legginess.
• Watch for spider mites.
• Short-lived novelty plant; loses sensitivity, rarely lasts >1 year.
• Leaf folding is a defense mechanism exposing thorns.
