Pot size

Small plants can be kept in 8cm pots until they start to grow near the edges of the pot, at which point they can be moved to larger pots. They should only be planted in a pot that is 3-5cm wider than their outermost stems.
Temperature

Humidity

Growing Season
Crassula ‘Dorothy’ grow throughout the year, but active growth slows down in peak winter and peak summer.
Propagation
Crassula ‘Dorothy’ is best propagated from stem cuttings.
Stem cuttings: Crassula is easy to propagate from stem cuttings. Only take cuttings in autumn and spring. Cuttings will not root well in mid-winter or summer. Simply use a sterilized sharp knife to remove a cutting from the main stem. Make sure it is at least one third of the size of the main stem of the plant before removing it, otherwise it may struggle to survive. Let this cutting air dry for two weeks. It should begin to produce aerial roots on its own. Plant the cuttings in the same soil as the mother plant.
