How to Care for Aloe Vera
Aloe barbadensis miller
Save
Aloe Vera (Aloe barbadensis miller) is one of the most useful plants you can keep indoors. It's drought-tolerant, thrives on neglect, looks great on a sunny windowsill, and its thick leaves are filled with a clear gel that's been used for centuries to soothe burns, cuts, and skin irritation. It's the original kitchen windowsill plant for a reason.
Native to the arid Arabian Peninsula and North Africa, Aloe Vera stores water in its fleshy leaves to survive long dry spells. That means the number one rule of indoor aloe care is simple: don't overwater it. Get that right and this plant will reward you for years — with proper care, aloe vera can live over a decade and produce pups annually.
Its upright rosette of serrated grey-green leaves adds sculptural presence to any space. Non-toxic to children when used topically, but toxic to cats and dogs if ingested, so keep it out of reach of pets.

Aloe Vera Care Guide
Watering: Water deeply and infrequently. Let the soil dry out completely — all the way through — before watering again. In spring and summer that's roughly every 2–3 weeks. In fall and winter when growth slows, stretch it to once a month or less. When you do water, pour until it drains from the bottom, then discard the runoff — never let aloe sit in standing water.
The most common way to kill aloe is overwatering. Mushy, translucent, or soft brown leaves at the base signal root rot — not underwatering.
Light: Aloe loves bright light and does best near a south or west-facing window indoors. It can handle direct sun, but transition it gradually over 1–2 weeks when moving to a sunnier spot — going from low light to full sun too quickly causes sunburn (leaves turn orange-brown and dry out). A north-facing window won't provide enough light for healthy growth long-term.
Soil & Potting: Always use a cactus or succulent mix. Improve drainage further by mixing in perlite or coarse sand. The pot must have drainage holes — no exceptions. Because aloe has shallow roots but heavy leaves, repot into a wider container (not necessarily deeper) when it starts to outgrow its pot to prevent tipping. Repot every 2–3 years or when roots are visibly crowded.
Fertilizer: Aloe is adapted to nutrient-poor desert soil and doesn't need much. If you want to fertilize, use a diluted cactus or succulent fertilizer once or twice during spring and summer only. Over-fertilizing causes weak, floppy growth and can burn the roots.
Humidity & Temperature: Unlike most houseplants, aloe prefers dry air. It handles low humidity without complaint and doesn't need misting — in fact, misting the leaves can promote rot. Keep it away from cold drafts and AC vents, and bring it inside before temperatures drop below 50°F (10°C).
Gel Use
This is what makes aloe genuinely useful, not just decorative. To harvest the gel, cut a mature outer leaf at the base with a clean sharp knife. Let the cut end drain for a few minutes — the yellow latex layer just beneath the skin is a laxative and can cause digestive irritation, so you want that to drain off before use. Slice the leaf open and scoop out the clear gel inside.
Apply topically to minor burns, sunburn, cuts, and skin irritation. Do a patch test first on sensitive skin. Do not ingest the gel or latex — despite some commercial products using food-grade aloe, the raw gel and especially the latex from a home plant can cause significant digestive issues.
Cultivars
Most plants sold as "aloe vera" are Aloe barbadensis miller, the standard medicinal variety. A few related species worth knowing:
- Tiger Aloe — smaller, with striking white horizontal banding on dark green leaves. More decorative than medicinal, but same basic care.
- Lace Aloe (Aloe aristata) — compact with white-tipped bumpy leaves. Notably more tolerant of lower light than standard aloe.
- Short-leaved Aloe (Aloe brevifolia) — small blue-green rosettes that clump readily and are very low maintenance.
All share the same core care: bright light, dry soil, infrequent watering.
Common Problems
Common Problems
- Mushy leaves or soft brown base: Root rot from overwatering. Remove from the pot, trim any black or mushy roots, let dry completely for several days, and replant in fresh dry cactus mix. Don't water again for at least a week.
- Thin, curling, or deflated leaves: Underwatering. Give a deep soak and leaves should plump back up within a day or two.
- Orange or crispy brown patches: Sunburn from transitioning to direct sun too quickly, or salt buildup from tap water. Flush the soil with distilled water and move out of harsh afternoon sun.
- Pale, yellow, or leggy growth: Not enough light. Move to a brighter spot — aloe reaching for light will grow tall, floppy, and weak.
- Drooping leaves: Usually underwatering, root rot, or insufficient light. Check the soil — if it's bone dry, water deeply. If it's wet, let it dry completely.
- Brown leaf tips: Common and often harmless — usually dry air or minor underwatering. Trim the tips if cosmetics matter.
- Mealybugs or scale: Rare indoors but possible. Treat with a cotton swab dipped in rubbing alcohol or diluted neem oil.
FAQs
Yes — cut a mature outer leaf at the base, let the yellow latex drain, scoop out the clear gel, and apply topically. Good for burns, sunburn, and minor skin irritation. Patch test first. Don't ingest the raw gel or latex.
Every 2–3 weeks in spring and summer, once a month or less in fall and winter. Always let the soil dry completely before watering. When in doubt, wait another week — aloe handles underwatering far better than overwatering.
Root rot from overwatering. Remove from the pot, trim mushy roots, let dry several days, and repot in fresh dry cactus mix. Don't water for at least a week after repotting.
Either underwatering, root rot, or insufficient light. Check the soil — bone dry means it needs water, soggy means root rot. Leggy drooping usually means it needs more light.
No. Aloe is a succulent adapted to dry conditions — prolonged water exposure causes the roots to rot. It cannot be grown hydroponically long-term.
Yes — toxic to cats and dogs if ingested. Keep it out of reach. It's safe for children's skin but the raw latex and gel shouldn't be ingested by anyone.
It's likely not old enough (3–5 years is typical), not getting enough light, or the pot is too large. A slightly pot-bound plant in bright light is most likely to produce pups. A spring fertilizer dose can also help encourage them.
It'll survive short-term but won't thrive. Low light causes pale, floppy growth and prevents pup production. A south or west-facing window is ideal.
Over ten years with good care. It's a long-lived plant that keeps producing pups throughout its life, so the lineage continues indefinitely even after the mother plant eventually declines.
