Everything it needs
9 essentials at a glance
Watering
Haworthia retusa prefers to dry out between waterings.
Water every 2-3 weeks during the growing season (spring and summer), allowing the top inch of soil to dry out completely before watering again. In fall and winter, reduce watering to once a month. Signs of over-watering include yellowing leaves and mushy stems, while under-watering may cause shriveling and browning of the leaf tips.
Light
This succulent thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, place it near a window that receives filtered light for about 6 hours a day. It can tolerate lower light conditions but may become leggy and lose its compact form.
Soil
Haworthia retusa prefers a well-draining soil mix, ideally a cactus or succulent potting mix with a pH range of 6.0 to 7.0.
Ensure the pot has drainage holes to prevent water accumulation, which can lead to root rot.
Humidity
This plant prefers low to moderate humidity levels, ideally around 30-50%.
To increase humidity, you can place a humidity tray filled with water near the plant or mist it lightly. Signs of low humidity stress include browning leaf tips and wilting.
Temperature
Haworthia retusa thrives in temperatures between 70-80°F (21-27°C) during the day and can tolerate cooler nights down to 50°F (10°C).
It is hardy in USDA zones 10-11, but should be protected from frost and extreme heat.
Fertilizing
Use a diluted, balanced fertilizer (NPK ratio of 10-10-10) during the growing season, applying every 4-6 weeks.
Avoid fertilizing in fall and winter when the plant is dormant. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Pruning is minimal for Haworthia retusa.
Remove any dead or damaged leaves at the base using clean, sharp scissors. This can be done at any time of year. Deadheading is not necessary for this plant.
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 current pot, shake off excess soil, and place it in fresh potting mix, ensuring the roots are spread out.
Propagation
Propagation can be done through offsets or leaf cuttings.
For offsets, gently separate them from the parent plant and allow them to callous over for a few days before planting in well-draining soil. For leaf cuttings, take a healthy leaf, let it callous for a few days, and then place it in soil. Best timing is during the growing season in spring or early summer.
