Overwatering on sedum lineare

sedum lineare with overwatering

What's Happening

Sedum lineare exhibits compromised growth due to rapid water consumption in green roof habitats. CAM (Crassulacean Acid Metabolism) photosynthesis requires distinct day/night cycles—stomata open at night to fix CO2, storing malic acid in vacuoles. Overwatering disrupts this drought-adapted metabolism. ABA (abscisic acid) signaling at 0.2 mg/L root application reduces transpiration without compromising CAM efficiency.

How to Fix It

  1. 1

    1. Check soil moisture with finger—water only when top 2-3 inches are completely dry

  2. 2

    2. Water deeply until water drains from bottom holes—discard excess after 30 minutes

  3. 3

    3. Provide bright indirect light during day, complete darkness at night to support CAM rhythm

What You'll Need

moisture meter perlite terracotta drainage tray

How to Prevent It

Water only when soil is completely dry to the touch (top 2-3 inches). CAM metabolism is disrupted by constant moisture—allow 7-14 days between thorough waterings depending on light and temperature.
