About Rock stonecrop
Petrosedum forsterianum, also known as Rock Stonecrop, is a low-growing perennial succulent that forms dense mats of compact rosettes. Its fleshy, blue-green leaves often develop reddish hues under intense sun. It's ideal for rock gardens, green roofs, gravel gardens, or as ground cover in dry, sunny locations.
Native range
Western and Central Europe
Care tips
It requires full sun for compact growth and good coloration; too much shade can make it leggy and weak. Watering should be infrequent, allowing the substrate to dry out completely between waterings, as it is very susceptible to rot from excessive moisture. Use a very well-draining substrate, preferably sandy or with plenty of perlite. A common mistake is overwatering, especially in winter, which can be fatal for the plant.
How to save a dying Rock stonecrop
- Warning signs
- Soft, yellowing or browning leaves, leaf drop, etiolated (long and weak) stems.
- First aid
- Remove plant, check roots (cut if rotted). Repot in dry, well-draining substrate. Place in bright indirect light.
- What kills it
- Overwatering, especially in winter or low light. Also prolonged lack of light causing etiolation.
- Can it be saved?
- Yes, if stems still have firm areas. Propagate healthy cuttings if the base is too damaged.
