How to Grow Aloe Vera
Aloe barbadensis miller
A popular succulent with thick, fleshy lance-shaped leaves containing soothing gel. Grows outdoors year-round in warm, dry climates (zones 9-12) and makes an excellent low-maintenance garden plant. Needs full sun to partial shade and very well-draining soil.
Yearly Lifecycle
Care Essentials
Feed once or twice during the growing season with a diluted succulent fertiliser. Aloe vera is a very light feeder.
Watch For
- Root rot from overwatering (most common problem)
- Aloe mites causing gall-like growths
- Soft, mushy leaves indicating cold damage

☀️ Light
Bright indirect light; tolerates some direct sun indoors
Place on a south- or east-facing windowsill for best results. Aloe vera can handle a few hours of direct indoor sun but will scorch if moved suddenly from low light to full summer sun.
💧 Watering
Water deeply, then allow to dry out completely
Water thoroughly when the top 2-3 cm of compost is bone dry, then leave until dry again. In winter reduce to once a month or less. Always use a pot with drainage holes.
🌱 Fertilizing
Light feed once or twice in the growing season
Apply a diluted balanced succulent fertiliser at half strength in spring and again in midsummer. Do not feed in autumn or winter when the plant is resting.
✂️ Pruning
Remove dead outer leaves and spent flower stalks
Cut off brown or dried outer leaves at the base with clean scissors. Remove spent flower stalks after blooming. No routine pruning is required.
🌿 Humidity
Low humidity preferred; avoid steam and damp
Aloe vera is a desert succulent and thrives in normal household humidity (30-50%). Keep away from kitchens and bathrooms where humidity is high.
🌿 Temperature
Minimum 10°C; protect from cold draughts
Aloe vera prefers temperatures of 15-27°C and will not tolerate frost. Keep away from cold windows in winter and avoid draughts from open doors.
Growing Tips
Let it dry out completely
Aloe vera stores water in its leaves — water only when the top 2-3 cm of compost is completely dry and the leaves start to look very slightly wrinkled. In winter, stop watering almost entirely.
Drainage is non-negotiable
Use a cactus and succulent compost mixed with extra horticultural grit. A terracotta pot with drainage holes is ideal — plastic pots retain too much moisture.
Plenty of light
Give aloe vera the sunniest windowsill or brightest spot in the room. It tolerates some direct sun indoors but will stretch and pale if the light is too low.
Harvest gel carefully
To use the gel, cut an outer leaf at the base cleanly with a sharp knife. Rinse off the yellow latex (aloin) near the cut end before using the clear gel — aloin can be a skin irritant.
Pests & Diseases
Pest Mealybugs
Identification: White waxy cottony masses in leaf axils and along leaf margins, often accompanied by sticky honeydew.
- Dab individual bugs with a cotton bud dipped in rubbing alcohol.
- Spray with a diluted neem oil solution, ensuring coverage of all crevices.
- Apply a systemic insecticide labelled for houseplants containing imidacloprid.
Pest Aloe Mites
Identification: Gall-like bumpy distortions on leaves and stems; tissue appears warty or tumour-like. Unlike spider mites, aloe mites are microscopic and not visible.
- Remove and destroy all affected leaves immediately — there is no reliable organic cure.
- Isolate the plant to prevent spread to other succulents.
- No widely available chemical cure; badly infested plants are best discarded.
Pest Scale Insects
Identification: Small brown or tan oval bumps attached to leaf surfaces and stems; scrape off to reveal soft body underneath.
- Scrape off scales manually with a soft toothbrush or fingernail.
- Wipe affected areas with a cloth dampened with diluted neem oil or insecticidal soap.
- Apply a systemic houseplant insecticide; repeat after 14 days.
Disease Root Rot Pythium spp. / Phytophthora spp.
Symptoms: Leaves turn yellow, brown, and mushy from the base upward; stem base feels soft; roots are black and smell unpleasant.
Treatment: Remove the plant from its pot, cut away all blackened roots with sterile scissors, dust cut ends with sulphur powder or cinnamon, and repot in fresh dry gritty compost. Allow the plant to dry out for several days before watering again.
Prevention: Always use free-draining compost; never let the pot sit in standing water; reduce watering significantly in winter.
Disease Aloe Rust Phakopsora pachyrhizi (similar fungal species)
Symptoms: Orange-brown powdery pustules on leaf undersides; corresponding yellow spots on upper leaf surface.
Treatment: Remove affected leaves; improve air circulation; apply a copper-based fungicide if severe.
Prevention: Avoid wetting the foliage when watering; ensure good ventilation around plants kept outdoors in summer.
