Everything it needs
9 essentials at a glance
Watering
Crassula Umbella prefers to dry out between waterings.
Water thoroughly every 2-3 weeks during the growing season (spring and summer) and reduce to once a month in fall and winter. Signs of over-watering include yellowing leaves and mushy stems, while under-watering may cause leaf shriveling and dropping.
Light
This plant thrives in full sun to partial shade, ideally receiving 6-8 hours of direct sunlight daily.
It can tolerate some shade but may become leggy if not given enough light. Ideal placement includes south or west-facing windows.
Soil
Crassula Umbella prefers well-draining soil with a pH range of 6.0 to 7.0.
A cactus or succulent potting mix is recommended, or you can create your own by mixing regular potting soil with sand and perlite for improved drainage.
Humidity
This succulent thrives in low to moderate humidity levels, ideally around 30-50%.
To increase humidity, you can group plants together or use a humidity tray. Signs of humidity stress include leaf curling and browning edges.
Temperature
The ideal temperature range for Crassula Umbella is between 65-80°F (18-27°C).
It is hardy in USDA zones 9-11 and can tolerate brief periods of cold down to 30°F (-1°C) but should be protected from frost.
Fertilizing
Use a balanced, diluted fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
Reduce feeding in fall and winter. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Prune Crassula Umbella in early spring to maintain its shape and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary, but removing spent flowers can promote a tidier appearance.
Repotting
Repot every 2-3 years or when the plant outgrows its pot.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes or stunted growth. To repot, gently remove the plant from its pot, shake off excess soil, and place it in fresh potting mix.
Propagation
Propagation can be done through leaf cuttings or offsets.
For leaf cuttings, take a healthy leaf, allow it to callous for 1-2 days, then place it in well-draining soil. Water sparingly until roots develop. The best time for propagation is in spring or early summer.
