Aloe Vera (Aloe barbadensis miller) is a rosette succulent with thick, fleshy, lance-shaped leaves filled with gel, arranged in a spreading rosette that slowly produces offsets. This guide covers everything it needs: light, water, humidity, temperature, soil, repotting, feeding, propagation and the common problems that show up when something is off. The care numbers below come from the Garden Grove plant database, so you can follow them with confidence.
Aloe vera is probably the most useful succulent you can grow: its thick, fleshy leaves are filled with a cooling gel that has been used on minor skin irritations for centuries, and the plant itself is handsome, with a spreading rosette of blue-green, serrated leaves. It is also one of the easiest succulents to keep, as long as you remember it is a desert plant — it wants bright sun, gritty soil that drains fast, and water only when the soil has dried out fully. Overwatering is the fastest way to kill it. Keep it away from pets, though: aloe vera is toxic to cats and dogs if eaten.

Light
Give your Aloe Vera bright direct light — a sunny windowsill is ideal, ideally with several hours of direct sun a day. Sunlight is what keeps it compact and colourful; in too little light it stretches, pales and loses its shape. Our grow-light calculator can help work out how much light your spot actually provides.
One caution: a plant bought from a shaded shop or greenhouse can scorch if it is put straight into harsh midday sun. Introduce it gradually over a week or two, increasing the sun a little each day. Once it is acclimatised, it will take full sun happily. Rotate the pot a quarter turn every couple of weeks so it grows evenly and does not lean towards the window.
Watering
Water every 2–3 weeks; let soil dry fully. Push a finger into the soil before you water: if it is still damp at all, wait; if it is dry all the way through, water thoroughly until water runs out of the drainage holes, then empty the saucer so the plant never sits in standing water. With succulents, the rule is simple — when in doubt, wait another few days.
Water less in winter, when growth slows and the soil stays wet longer, and a little more in summer, when the plant is actively growing. If you want a routine rather than guesswork, our watering calculator gives a starting point for your pot size, and the watering schedule generator can help you build a habit around it. Signs of overwatering include soft, mushy leaves and a soft stem base; signs of underwatering include wrinkled, deflated leaves that plump up again after a good watering.
Humidity and temperature
Aloe Vera prefers low humidity and temperatures of 60–80°F. That low humidity is good news: most homes are dry enough already, and this plant will not need a humidifier, a pebble tray or a bathroom spot. In fact, damp, stuffy air is more of a risk than dry air, so give it good air circulation and avoid crowding it among humidity-loving plants.
Temperature is rarely a problem indoors, since most homes sit inside the 60–80°F range for most of the year. The things to watch are cold draughts in winter and cold windows that chill the leaves overnight, and sudden temperature swings near heating vents. Keep the plant away from radiators too — not because of the heat, but because the dry, hot air can scorch the leaves. Our humidity and temperature checker can tell you whether your room suits this plant.
Soil and potting
Aloe Vera needs a very free-draining, gritty mix — this is the single most important part of its care. Standard potting soil on its own holds far too much water, so mix it half and half with perlite, pumice or coarse grit, or use a ready-made cactus and succulent mix. A pot with drainage holes is not optional; without one, water has nowhere to go and root rot follows. Terracotta pots are a good choice because they breathe and help the soil dry out. Our potting-mix calculator can work out the parts for a homemade mix for your pot size.
Top-dressing with a layer of grit or small stones keeps the base of the leaves dry and looks tidy, but it is optional. What matters is that water passes through the mix quickly and the soil dries out fully between waterings. Never use a saucer that holds standing water under a succulent.
Repotting
Repot every 2–3 years, or sooner if roots are circling the drainage holes or pushing out of the top of the pot. Move up only one pot size — a pot that is too big holds wet soil the roots cannot use. Spring is the best time to repot, when the plant is about to grow, and fresh mix gives the roots a new supply of air and nutrients. Our repotting calculator can help you work out the next pot size and how much fresh mix you will need.
When you repot, take the chance to inspect the roots: healthy roots are firm and pale, while black, mushy roots are rotted and should be trimmed away with clean scissors. Tease out the bottom of the root ball gently so the roots can grow into the fresh mix, set the plant at the same depth it was growing before, and water it in well. Do not repot a stressed or sick plant unless the pot or soil is the cause of the problem — repotting is a shock, and a struggling plant recovers better once the underlying issue is fixed.
Feeding
Feed during the growing season, in spring and summer, with a balanced liquid houseplant fertiliser at half the strength on the label, and do not feed in autumn and winter when the plant is barely growing. Always follow the directions on the label — more fertiliser is not better, and excess salts build up in the soil and burn the roots, which often shows up as brown leaf tips. If you have been feeding heavily, flush the soil with plain water every few months to wash the salts out. A plant that was recently repotted into fresh mix needs no extra food for the first couple of months, since fresh mix already contains nutrients.
Propagation
Aloe Vera is propagated from the offsets, or pups, that form around the base of a mature plant. In spring or summer, gently separate a pup that has a few leaves and its own roots, let the cut end dry for a day or two, then pot it in a very free-draining, gritty mix and water sparingly until it establishes. Leaf cuttings do not reliably root, so pups are the method to use. A healthy plant produces pups freely, so you will rarely be short of new plants to share.
Common problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Wrinkled leaves | Underwatering | Water thoroughly and let the excess drain away, then water again when the soil has dried fully. |
| Sunburn spots | Sudden harsh direct sun | Move the plant out of harsh direct sun and into bright light that is indirect, or introduce it to sun gradually. |
| Mushy leaves | Overwatering / root rot | Stop watering immediately and let the soil dry out fully. |
Wrinkled leaves
Likely cause: underwatering. Water thoroughly and let the excess drain away, then water again when the soil has dried fully. If the leaves stay wrinkled while the soil is wet, check the roots for rot.
Sunburn spots
Likely cause: sudden harsh direct sun. Move the plant out of harsh direct sun and into bright light that is indirect, or introduce it to sun gradually. Burnt spots will not heal, but new growth should come out clean.
Mushy leaves
Likely cause: overwatering / root rot. Stop watering immediately and let the soil dry out fully. If the base is soft, take the plant out, cut away any rotted parts, let the cuts dry, and repot in dry, gritty mix. Only water again once the plant shows signs of recovery.
Frequently asked questions
How often should I water aloe vera?
Water every 2–3 weeks; let soil dry fully. Always check the soil with a finger first rather than watering on a fixed day, because the interval changes with the season, the pot size and the warmth of the room. Water thoroughly when the soil is dry enough and let the excess drain away completely, and never let the plant sit in standing water.
What light does aloe vera need?
It needs bright direct light. A spot near an east- or west-facing window usually suits it well. Too little light gives slow, weak growth, while harsh midday sun can scorch the leaves — use the guidance in the Light section above to place it well.
Is aloe vera safe for cats and dogs?
According to the data used for this guide, aloe vera is toxic to cats and dogs. Keep it out of reach of pets that chew plants, and if a pet eats any of it, contact your vet.
Can I use the gel from my aloe vera plant on my skin?
The gel inside the leaves has traditionally been used on minor skin irritations. If you use it, cut a thick outer leaf, let the yellow sap drain away, and scoop out the clear gel. Stop using it if your skin reacts, and do not eat the plant — aloe vera is toxic to cats and dogs and is not a medicine.
When should I repot aloe vera?
Repot every 2–3 years, in spring, or sooner if roots are circling the drainage holes. Move up one pot size only and use a fresh mix suited to this plant — see the Soil and potting section above. If you are also growing other houseplants, the same repotting routine works for them — browse the houseplants hub for more care guides in this series.
