How to Care for Haworthia
1. Light Requirements
Haworthia plants thrive in bright, indirect light. They can tolerate direct morning sunlight but should be shielded from intense afternoon sun, which can scorch their leaves. Indoors, place them near an east- or west-facing window for optimal growth.
Signs of Too Much Sun:
Leaves turning red, yellow, or white (indicates sunburn)
Shriveling or browning of leaf tips
Signs of Insufficient Light:
Fading green color
Slow or leggy growth
2. Soil and Potting Mix
To prevent root rot, Haworthias require well-draining soil. Use a cactus or succulent potting mix, or create your own by mixing:
50% coarse sand or perlite
30% potting soil
20% pumice or gravel
A pot with drainage holes is essential to prevent excess moisture retention.
3. Watering Schedule
Overwatering is the most common issue with Haworthia plants. Water your plant when the top inch of soil is completely dry.
Spring/Summer: Water every 1-2 weeks
Fall/Winter: Reduce watering to once a month or when the leaves start to wrinkle slightly
Avoid letting water collect in the rosette, as this can lead to rot.
4. Temperature and Humidity
Haworthia thrives in warm temperatures between 70-95°F (21-35°C) and can tolerate cooler temperatures down to 50°F (10°C). They should be protected from frost, as temperatures below 40°F (4°C) can be damaging. Good air circulation is essential, so avoid placing them in overly humid environments.
5. Fertilizing Haworthia
Feed Haworthia with a diluted cactus fertilizer during the growing season (spring and summer). Avoid fertilizing in fall and winter when the plant is dormant.
Propagating Haworthia
The easiest and most effective way to propagate Haworthia is through offsets, or “pups,” which grow at the base of the parent plant.
Step-by-Step Propagation Guide
Wait for Offsets: Allow small pups to develop around the base of the plant.
Separate the Offsets: Use a clean, sharp knife to cut the pup away, including as many roots as possible.
Let It Dry: Leave the offset in a dry, shaded area for 24 hours before planting.
Replant: Use the same well-draining soil mix as the parent plant.
Water Sparingly: Wait a few days before watering to prevent rot.
Common Issues and Solutions
1. Pests (Mealybugs & Fungus Gnats)
Solution: Remove mealybugs manually with alcohol-soaked cotton swabs; reduce moisture levels to prevent gnats.
2. Yellow or Red Leaves
Cause: Too much direct sunlight
Solution: Move to a slightly shadier location
3. Drooping or Mushy Leaves
Cause: Overwatering leading to root rot
Solution: Let soil dry out completely before watering again; repot if necessary
