Description
Haworthia truncata is a small succulent plant with gray or gray-green leaves that have a nearly rectangular cross-section and a rough upper surface, giving the impression of being cut. It can slowly grow up to 0.8 inches (2 cm) tall with a spread of 4 inches (10 cm). The leaves are more or less upright, tightly appressed, and arranged in 2 opposite rows.
The small white flowers appear on slender stalks that can grow up to 8 inches (20 cm) long, mainly in late spring.
How to Grow and Care for Haworthia truncata
Light: Place the potted plant in a bright area with some protection from the hottest rays of the day. White, yellow, or red-tinged leaves usually indicate that your H. truncata receives too much sunlight. Deep shade tends to weaken the plant over a prolonged period. If your plant has spent the winter indoors, gradually move it outdoors into the bright sun to prevent sunburn.
Soil: Like all Haworthias, this plant does not like its roots to remain wet for prolonged periods, so the soil should be well-drained. You can use a commercial potting mix for succulents or make your own.
Hardiness: This succulent likes warmer temperatures in the summer but cool in the winter. However, it does not like being too cold. H. truncata can withstand temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: In spring and fall, when the growth is most active, water H. truncata thoroughly, then wait until the top of the soil dries out before watering again. Water your plant less during the winter when its growth slows down significantly. During the hottest summer months, when this plant is mostly dormant, water it just enough to keep the leaves from shriveling.
Fertilizing: H. truncata does not require much fertilizer. However, for optimum growth, fertilization is a good idea. Feed only with a dilute fertilizer and only during the active growing season.
Repotting: This slow-growing succulent can stay in the same pot for years. To keep your plant healthy and happy, repot H. truncata into fresh soil every two to three years in spring or fall. Repotting time is also the time to take offsets for propagation.
Propagation: Vegetative propagation, especially by offsets, is the quickest and most common method of propagating H. truncata. This plant can also be propagated by leaves and seeds. Remove the offsets when they have started developing their own roots. Sow seeds in spring or fall in a well-draining soil mix.
