How much sun does an aloe vera need indoors?

Four to six hours of bright light a day, ideally a south- or west-facing window. Aloe is a desert succulent and stretches, pales, and flops when it does not get enough — a plant leaning hard toward the glass or growing thin, floppy leaves is asking for more light. That said, an aloe moved abruptly from a dim corner into full summer sun can sunburn, showing brown or reddish patches, so increase light gradually over a week or two. Under weak winter light, a grow light keeps the rosette compact.

Why are my aloe leaves turning brown or mushy?

Mushy, translucent, water-soaked leaves mean overwatering and the start of root rot, the number-one killer of aloe. The fix is to let the soil dry completely, cut back watering, and if the base is soft, unpot and check the roots. Dry, thin, brown-tipped or curling leaves point the other way — underwatering or scorching sun. Firm leaves that flush reddish-brown are usually sun stress and not harmful. Match the symptom to the cause before you reach for the watering can, because watering a rotting aloe finishes it off.

Do aloe vera plants need fertilizer?

Very little. Aloe evolved in poor, gritty soils and grows fine with no feeding at all for a season. If you want to push growth, use a balanced houseplant fertilizer or a succulent formula diluted to half strength, no more than once a month in spring and summer, and never in fall or winter when the plant is resting. Overfeeding causes weak, floppy growth and salt buildup in the mix that damages roots. When in doubt, feed less; a starved aloe recovers far more easily than an overfed one.

How do I know when to repot my aloe?

Repot when the plant is clearly crowded — roots circling out the drainage holes, the rosette wider than the pot, or a cluster of pups filling the surface. Most aloes need repotting every two to three years, best done in spring. Move up just one pot size; aloe actually flowers and stays sturdier when slightly root-bound, and an oversized pot holds too much wet soil around the roots. Always use a fresh gritty succulent mix and a container with a drainage hole, and let a repotted aloe sit dry for about a week before the first watering.

Is aloe vera safe around pets?

No. Aloe vera is toxic to cats and dogs — the latex just under the leaf skin contains compounds that cause vomiting, diarrhea, and lethargy if a pet chews the leaves. Keep the plant on a high shelf or in a room pets cannot reach. The clear inner gel used on human skin is the low-risk part, but pets bite through the whole leaf, so treat the plant as unsafe around animals.

Aloe vera care comes down to three things: bright light, gritty fast-draining soil, and watering only when the mix is completely dry. Give it four to six hours of bright light a day, plant it in a cactus or succulent mix in a pot with a drainage hole, and water deeply but infrequently — roughly every two to three weeks indoors, and far less in winter. Get those right and aloe is close to unkillable; get watering wrong and it rots from the base within weeks. Almost every struggling aloe is not underloved but overwatered.

Aloe vera (Aloe barbadensis) is a desert succulent that stores water in its thick leaves, so it is built to survive drought and to resent wet feet. We do not physically grow or test the plants and products we cover; this guidance reflects horticultural consensus and aggregated grower experience, as described in how we rank.

Aloe Vera Light: Bright, and Plenty of It

Aloe wants the brightest spot you can give it indoors — a south- or west-facing window with four to six hours of direct or very bright light. In good light the rosette stays compact, the leaves plump and upright, sometimes blushing a healthy reddish tint at the tips. In too little light, aloe etiolates: the leaves grow thin, pale, and floppy, and the plant leans toward the window trying to find more sun.

The one caution is a sudden move into intense sun. An aloe that has lived in a dim corner can scorch when abruptly placed in full summer glass, showing brown or bleached patches. Increase its exposure over a week or two. If your brightest window still is not enough, especially in northern winters, a modest grow light keeps the plant tight and healthy — see our grow light picks.

Watering Aloe Vera: The Make-or-Break Skill

The golden rule is to water thoroughly, then wait until the soil is bone dry before watering again. When you do water, soak the mix until it runs from the drainage hole, then empty the saucer so the pot never stands in water. In a bright indoor spot that usually works out to every two to three weeks in the growing season and once a month or less in winter, but always test by feel, not by the calendar.

Push a finger two inches into the soil, or lift the pot — a dry pot is noticeably light. Only water when the mix is fully dry. When leaves look thin, curled, or puckered, the plant is genuinely thirsty. When leaves go soft, translucent, or mushy at the base, you have overwatered and rot is starting. For the full watering schedule by season and pot size, see how often to water aloe vera.

Leaf sign	What it means	Action
Plump, firm, upright	Well hydrated	Nothing — keep the routine
Thin, curling, puckered	Underwatered	Water deeply once, then resume normal spacing
Soft, mushy, translucent, brown at base	Overwatered, rot starting	Stop watering, dry out, check roots
Reddish-brown flush, still firm	Sun stress, harmless	Reduce direct sun slightly if unwanted
Brown crispy tips	Underwatering or dry air	Water on schedule; usually cosmetic

Soil and pot: drainage above all

Aloe must have a fast-draining, gritty medium. A bagged cactus and succulent mix works straight from the bag; a standard potting mix holds far too much water and will rot the roots. If you only have regular potting mix, cut it heavily with perlite, coarse sand, or pumice — roughly one part grit to two parts mix — to open it up. What kills aloe is soil that stays wet, so err toward gritty.

The pot matters just as much. Always use a container with a drainage hole; a pot without one traps water at the roots no matter how careful you are. Terracotta is ideal because it is porous and wicks moisture out of the mix, giving you a wider margin for error on watering. Size up only one pot at a time — aloe is happiest slightly snug.

Temperature and humidity

Aloe is comfortable in ordinary home conditions, roughly 55 to 80 F, and actively dislikes the humidity and misting that tropical houseplants enjoy. It tolerates dry indoor air perfectly well, so skip the pebble tray and the humidifier — extra moisture only raises the rot risk. Keep it away from cold drafts and never let it sit below about 50 F for long; aloe is not frost-hardy and cold, wet conditions are a fast route to collapse. In summer it enjoys a spell outdoors in a bright, sheltered spot, brought back in before nights turn cold.

Feeding: less is more

Aloe needs almost no fertilizer. It grows in nutrient-poor desert soils in the wild and will do fine unfed for a full season. If you want to encourage growth, feed no more than once a month in spring and summer with a balanced or succulent-specific fertilizer diluted to half the label strength, and stop entirely in fall and winter. Overfeeding produces soft, weak, floppy leaves and leaves a salt residue in the mix that burns the roots. A lightly fed or unfed aloe is a sturdier aloe.

Repotting Aloe Vera and Its Pups

A healthy aloe produces offsets — small clones called pups — around its base, and over a couple of years the plant crowds its pot. Repot every two to three years in spring, moving up just one pot size into fresh gritty mix. When you unpot, gently separate any well-rooted pups and pot them individually to make new plants; the full method is in how to grow aloe vera and how to propagate aloe vera. After repotting, wait about a week before watering so any damaged roots can heal, which prevents rot entering the fresh wounds.

Common problems, quickly diagnosed

Base going soft and brown: root and stem rot from overwatering. Unpot, cut away all mush, let the healthy tissue callus, and re-root the top in dry gritty mix.
Leaves flat and splaying outward: too little light. Move to a brighter window or add a grow light.
Brown spots after a move: sunburn from a sudden increase in direct sun. Acclimate gradually next time.
Leggy, stretched stem: chronic low light; the fix is more light, and you can behead and re-root the compact top.
No new growth in winter: normal dormancy. Water sparingly and wait for spring.

Trimming damaged or overgrown leaves is covered in how to prune aloe vera, and if you have overdone the watering, how to save an overwatered plant walks through the rescue. The same dry-loving approach applies across succulents generally at the houseplants hub.
