Sensitive Plant (Mimosa pudica) Care: Light, Water, and Pruning for Healthy Growth

The sensitive plant (Mimosa pudica) is famous for its leaves that fold up when touched, but it’s also prone to leaf drop if conditions aren’t right. This tropical native needs specific care to thrive indoors.

Optimal Conditions

• Light: Bright, indirect light with some gentle morning or late afternoon sun. A north window alone may be too dim.
• Temperature: Keep above 60°F (15°C). Cold drafts cause leaf loss.
• Water: Maintain evenly moist soil—water when the surface feels dry. Never let it sit in water. The roots need a brief dry period to "breathe" (absorb CO₂ from soil air). Constant moisture suffocates them.
• Humidity: High humidity helps. Use a pebble tray or group with other plants.

Pruning and Pest Control

Pinch back stems regularly to encourage bushy growth and prevent legginess. Watch for spider mites—look for fine webbing in leaf axils. If found, spray daily with room-temperature water for a week to dislodge them.

Seedling roots rot quickly in heavy soil. Use a light, well-draining mix with perlite. With attentive care, your sensitive plant will reward you with its fascinating movements and delicate pink flowers.
