How to Grow Haworthia
Haworthia fasciata
Haworthia is one of the easiest succulents to grow indoors, tolerating low light levels that would stress most other succulents. It thrives on a bright windowsill with indirect light, infrequent watering, and well-draining cactus compost. Water only when the soil is completely dry, and avoid direct midday sun which can scorch the leaves.
Yearly Lifecycle
Care Essentials
Feed monthly with a dilute cactus and succulent fertiliser during spring and summer only. Do not feed in autumn or winter.
Watch For
- Mealybug
- Root rot from overwatering
- Vine weevil grubs
- Fungus gnats

☀️ Light
Bright indirect light — no direct midday sun
An east or north-facing windowsill is ideal in the UK. Avoid south-facing windowsills in summer as intense direct sun bleaches and scorches the leaves.
💧 Watering
Only when soil is completely dry
Water thoroughly, then allow the compost to dry out completely before watering again. In winter reduce to once a month or less. Bottom watering (placing the pot in water briefly) is preferred.
🌱 Fertilizing
Monthly with dilute cactus feed in spring and summer only
Apply a quarter-strength cactus and succulent fertiliser monthly from April to September. Do not feed in autumn or winter when the plant is dormant.
✂️ Pruning
Remove dead or dried outer leaves as needed
Peel away dead outer leaves cleanly at the base. Remove any flower stalks after flowering if not setting seed. No other pruning required.
🌿 Temperature
Keep above 5°C; avoid cold draughts
Haworthia tolerates temperatures down to about 5°C but prefers 10-25°C. Avoid positioning near cold draughty windows in winter. It is not frost-hardy and must be kept indoors year-round in the UK.
Growing Tips
Water sparingly — less is more
The most common cause of haworthia death is overwatering. Water thoroughly, then wait until the soil is completely dry before watering again. In winter, once a month or less is sufficient.
Indirect light is ideal
Haworthia thrives on a bright windowsill with indirect light. Avoid direct midday sun which will bleach and scorch the leaves. East or north-facing windowsills work well in UK homes.
Well-draining compost is essential
Always use cactus and succulent compost, or mix standard potting compost with 50% perlite or coarse grit. Standard multipurpose compost retains too much moisture and causes root rot.
Offset division refreshes plants
Haworthia naturally produces offsets (pups) around the base. Separate these in spring using a clean knife, allow the cut to dry for a day, then pot into dry cactus compost and water after a week.
Pests & Diseases
Pest Mealybug
Identification: White cottony clusters in leaf axils and between leaves; sticky honeydew residue.
- Dab individual bugs with a cotton bud dipped in rubbing alcohol.
- Apply neem oil solution to affected areas.
- Systemic insecticide drench as a last resort.
Pest Vine Weevil
Identification: C-shaped white grubs in the compost; plant suddenly collapses at the base.
- Apply Steinernema kraussei nematodes to moist warm compost in spring or autumn.
- Imidacloprid compost drench.
Pest Fungus Gnat
Identification: Tiny black flies hovering around the compost; larvae feed on roots in wet compost.
- Allow compost to dry out completely between waterings.
- Apply Steinernema feltiae nematodes to moist compost.
- Yellow sticky traps to catch adults; compost drench with imidacloprid for severe infestations.
Disease Root Rot Pythium / Phytophthora spp.
Symptoms: Mushy, translucent, or blackened leaves at the base; foul smell; plant collapses.
Treatment: Remove from pot immediately. Cut away all soft, rotted roots and leaves with a clean knife. Allow to dry for 2-3 days, then repot in fresh dry cactus compost. Do not water for 2 weeks.
Prevention: Use free-draining cactus compost. Never allow water to sit in the saucer. Reduce watering drastically in winter.
Disease Rust Spots / Corky Scab Abiotic / minor fungal infection
Symptoms: Brown, reddish, or corky raised spots or patches on the leaf surface.
Treatment: Remove severely affected leaves. Improve air circulation and reduce humidity.
Prevention: Avoid wetting the leaves when watering. Ensure good ventilation around the plant.
