How often to water Moses-in-the-cradle
- Spring–Summer (Mar–Sep)
- Every 5 days
- Water thoroughly a day or two after the topsoil dries, as a guide; the fleshy leaves store water, so avoid a soggy mix.
- Autumn (Oct–Nov)
- Every 7 days
- Drying slows in autumn; generally wait two to three days after the soil dries.
- Winter (Dec–Feb)
- Every 14 days
- Water sparingly about a week after the soil dries; keeping it on the dry side helps it tolerate cold.
Light and placement for Moses-in-the-cradle
