How to grow haworthia
Overview
Haworthiopsis attenuata, commonly known as haworthia, is a small, clump-forming succulent from South Africa, grown for its attractive rosettes of dark green leaves with white tubercles. It is ideal as an indoor or patio plant in Australia, tolerating low light and infrequent watering. Key to success is providing excellent drainage and avoiding prolonged wet soil.
Varieties
- Haworthiopsis attenuata 'Variegata' — A variegated form with cream or yellow stripes, popular in Australian collections for its striking appearance.
Soil Preparation
Use a very free-draining mix: 2 parts coarse sand or perlite to 1 part potting mix, or a commercial cactus mix. Ideal pH is 6.0–7.0. Ensure the pot has a drainage hole; avoid heavy clay or water-retentive soils.
Growing Guide
Plant haworthia in a free-draining succulent or cactus mix, in a pot with drainage holes. Position in bright, indirect light or morning sun, avoiding harsh afternoon rays. Space offsets 5–10 cm apart when dividing. Water sparingly, allowing soil to dry completely between drinks. In temperate zones, grow indoors or in a sheltered spot; in subtropical areas, protect from heavy summer rain by placing under cover.
Care
Feed with a diluted liquid succulent fertiliser once in spring and once in autumn. Remove dead or shrivelled lower leaves to keep the rosette tidy. Repot every 2–3 years into fresh mix to prevent soil compaction and replenish nutrients.
Companion Planting
Pair haworthia with other small succulents like Echeveria, Sedum, or Crassula in a mixed pot or dish garden. Avoid planting near moisture-loving plants such as ferns or impatiens, which can lead to overwatering and root rot.
Common Pests & Risks
Mealybugs are the most common pest, appearing as white cottony masses in leaf axils; control with a cotton swab dipped in alcohol or use neem oil. Root rot from overwatering is the main disease; prevent by using a well-draining mix and allowing soil to dry completely.
Troubleshooting
Yellow leaves: usually from overwatering; reduce watering and check drainage. Brown leaf tips: caused by too much direct sun or low humidity; move to brighter indirect light. Soft, mushy leaves: sign of root rot from wet soil; repot into dry mix and cut away damaged roots. Leggy growth: insufficient light; move to a brighter spot. White spots on leaves: likely mealybugs; treat with alcohol or neem oil.
