Water:
Thriving in rocky terrains, rockcresses efficiently retains moisture, requiring weekly watering. It exhibits drought tolerance and prefers drier environments, balancing hydration and drainage. Typically grown outdoors, rockcresses flourishes with monitored soil moisture levels to prevent waterlogging, especially during its active growing season.
Propagation:
The primary propagation method for rockcresses is seed sowing. Successful germination requires adequate light, temperatures of 21-23°C (70-75°F), and well-draining soil. Seed stratification can assist in some climates. Avoid damping off by using sterile potting mix and providing indirect light until germination.
