Description
Aloe marlothii is a large succulent with a usually unbranched stem topped with a rosette of stiff grey-green to blue-green leaves with a sharp point and reddish-brown spines along the margins and randomly on both surfaces. The leaves lose many of the spines from the surfaces as the plant becomes older. They are up to 5 feet (1.5 m) long and 10 inches (25 cm) wide. The stem grows to 10 feet (3 m) tall, usually covered by the withered old leaves. Flowers are orange to bright red and appear in late fall and winter on a wide-spread branching panicle with up to 30 racemes.
Etymology
The specific epithet "marlothii" honors the South African botanist Rudolf Marloth (1855-1931).
How to Grow and Care for Aloe marlothii
Light: When growing Aloes indoors, place your plants near a southern or southwest-facing window that gets 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 marlothii can withstand temperatures as low as 20 to 50 °F (-6.7 to 10 °C), USDA hardiness zones 9a 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 it from becoming rootbound.
Propagation: Propagating Aloe can be done by using the offsets, cuttings, or seeds from a mature plant.
