Description
Aloe dorotheae is an eye-catching succulent that forms rosettes of shiny yellowish-green leaves that turn orange-red in full sun. It can grow up to 12 inches (30 cm) tall and freely produce offsets, forming large clumps of rosettes growing on sprawling or decumbent stems. The leaves are thick, fleshy, and recurved, with teeth along the margins and often with some white spots.
The flowers are tubular, orange-red, or yellow with green tips. They appear on usually unbranched flower stalks that can grow up to 2 feet (60 cm) long in winter.
How to Grow and Care for Aloe dorotheae
Light: When growing Aloes indoors, place your plants in a southern or southwest-facing window with plenty of bright, indirect light. Outdoors provide light shade, especially during the hottest parts of the day.
Soil: Plant Aloes in well-drained soil specially formulated for cacti and other succulents, or make your soil mix. Drainage is essential because too much moisture around roots can cause root rot.
Hardiness: Aloe dorotheae can withstand temperatures as low as 25 to 50 °F (-3.9 to 10 °C), USDA hardiness zones 9b to 11b.
Watering: These succulents need regular watering but are very tolerant of drought conditions for short periods. Water deeply, but only when the soil is dry. Cut back on watering during the winter months.
Fertilizing: Aloes generally do not require fertilizer but may benefit from the extra nutrients.
Repotting: These plants are not particularly fast-growing and will only rarely need repotting. Repot them in the spring in a container a few inches larger in diameter every few years to keep them from becoming rootbound.
Propagation: Propagating Aloe can be done using offsets, cuttings, or seeds from a mature plant.
