What to Do About Black Spots on Your Sempervivum tectorum

Identifying Black Spots

🕵️‍♂️ Recognizing Symptoms

Black spots on Sempervivum tectorum leaves can start as small, dark blemishes, potentially expanding into larger lesions with distinct characteristics. Look for:

• Irregular or circular spots, dark brown to black in color.
• Spots that may have concentric rings or feathery margins.
• A yellow halo around the spot, which often indicates a fungal issue.
• Tiny black dots within the spots, which could be fungal fruiting bodies.
• Changes in the leaf's texture at the site of the spot, such as being water-soaked, dry, or brittle.

🌡 Assessing Plant Health

To determine the underlying cause of black spots, consider the plant's overall health and environmental conditions:

• Check for overwatering by observing if the soil is consistently soggy or if there's a water-soaked appearance to the leaves.
• Feel the spots; squishy spots may suggest overwatering, while crispy ones could indicate sunburn.
• Inspect for physical damage, such as tears or punctures that could have led to black spots.
• Evaluate environmental stress by considering recent changes in temperature, light exposure, or humidity levels.
• Monitor the plant's response to adjustments in care; persistent or worsening spots despite improved conditions could point to a fungal infection.
