How to Care for Aloe Vera Plant
How to care for aloe vera plant comes down to five things: strong indirect light, gritty fast-draining soil, a soak-and-dry watering routine, a warm room, and knowing when to leave it alone. Aloe vera is a succulent, not a tropical houseplant, and most of the plants that die on a windowsill die from too much water, not too little.
Light: bright, but ease it in
Aloe wants several hours of bright light a day. North Carolina State Extension lists aloe vera's light range as full sun (6+ hours of direct sun) to partial shade (2-6 hours), and a plant moved suddenly from a dim room into strong direct sun can sunburn, showing up as brown or bleached patches on the leaves. If you're moving a plant from a dim corner to a sunny windowsill or outdoors for summer, do it gradually over 7-10 days, adding an hour or two of direct sun at a time. A south- or west-facing window is usually the best year-round spot indoors. If the leaves turn thin, pale, and start reaching sideways toward the glass, that's a light problem, not a watering one - move it closer to the window.
Soil: fast drainage matters more than fertility
Aloe roots rot in soil that stays wet. Use a cactus/succulent mix, or build your own with roughly equal parts:
- Potting soil
- Coarse sand or perlite
- Pumice, crushed lava rock, or fine gravel
North Carolina State Extension's plant profile calls for very well-drained soils suitable for succulents - regular bagged potting soil on its own holds too much water and stays damp for days, which is exactly what causes rot. Always use a pot with a drainage hole. Unglazed terracotta is a good choice because the porous walls let extra moisture evaporate; plastic and glazed ceramic hold moisture longer, so water less often in those.
Watering: soak, then let it go bone dry
This is the step most people get wrong. Aloe stores water in its leaves and is built for drought, not a weekly watering schedule. NC State Extension's guidance is direct: allow the soil to completely dry between waterings, and avoid overwatering because it leads to root rot.
In practice:
- Push a finger about 2 inches into the soil. If it's still damp, wait.
- Once it's fully dry, water thoroughly until it runs out the drainage hole.
- Empty the saucer - don't let the pot sit in standing water.
Depending on pot size, soil mix, and room conditions, that usually lands somewhere around every 2-3 weeks in spring and summer and closer to once a month or less in fall and winter, when growth slows down. Treat those numbers as a starting point, not a rule - the finger test is what actually tells you when to water, since a small terracotta pot in a dry room dries out much faster than a large plastic one.
Mushy, translucent, or collapsing leaves near the base almost always mean overwatering and early rot, not underwatering. Underwatered aloe looks different: leaves get thin, curled, and puckered but stay firm.
Temperature
Aloe is comfortable at typical indoor temperatures, roughly 55-80°F, and does not tolerate frost. If it spends summer outside, bring it in before nighttime temperatures drop into the 40s. Cold, wet soil is worse than cold alone - a chilled plant sitting in damp soil rots fast.
Feeding
Aloe doesn't need much fertilizer. A diluted balanced houseplant or cactus fertilizer once every 4-6 weeks during spring and summer is plenty. Skip feeding entirely in fall and winter - the plant isn't actively growing, and extra fertilizer just builds up salts in the soil.
Repotting
Repot every 2-3 years, or sooner if roots are pushing out of the drainage hole or the plant has gotten top-heavy and started tipping over. Slide the plant out, shake off the old soil, and check the roots - trim off any that are dark, mushy, or hollow. Move up one pot size, not a much bigger pot, since oversized pots hold excess moisture longer than the roots can use. Use a fresh succulent mix, and hold off on watering for about a week after repotting to let any cut or damaged roots dry and callus, which lowers the odds of rot setting in.
Propagation: dividing the pups
Mature aloe plants send up offsets, commonly called "pups," around the base of the main rosette. NC State Extension notes aloe vera spreads by offsets and can be propagated by division. To separate them:
- Wait until a pup has its own few sets of leaves and ideally its own roots, usually a few inches tall.
- Unpot the whole plant and gently work the pup free from the parent, keeping as much root as possible.
- Let the pup sit somewhere dry and out of direct sun for a day or two so the cut or torn area calluses over.
- Pot it in dry succulent mix and skip watering for about a week, then resume the normal soak-and-dry routine.
Planting a fresh-cut offset straight into wet soil is a common way to lose it to rot before it's even rooted, so let that callus form first.
Pests
Aloe isn't a pest magnet, but mealybugs, spider mites, and aphids do show up occasionally.
- Mealybugs: small white cottony clumps, usually in leaf joints.
- Spider mites: fine webbing and stippled, dull-looking leaves; more common in dry, poorly ventilated rooms.
- Aphids: small clustered insects on new growth or near flower stalks.
For light infestations, wipe pests off with a damp cloth or a cotton swab dipped in rubbing alcohol. For anything heavier, spray insecticidal soap or a neem oil solution, coating the undersides of leaves, and repeat every 7-10 days until it's clear. Isolate a badly infested plant from others while you treat it.
Rot and other problems
Root and stem rot is the most common way aloe plants actually die, and it's almost always from watering on a fixed schedule instead of by soil dryness, or from a pot with no drainage hole. If the base looks mushy or smells sour, unpot it, cut away every soft or brown root and any mushy stem tissue back to firm white tissue, let the cut surfaces dry for a day or two, and replant in dry soil. Don't water again until you see new growth.
Brown, crispy leaf tips are usually just tap water fluoride or mineral buildup, or occasional underwatering, not an emergency. Leaning, leggy growth with wide gaps between leaves means the plant needs more light, not more water or fertilizer.
Is aloe vera safe to have around pets and kids?
Be honest with yourself about this one before putting it somewhere a cat, dog, or toddler can reach it. The clear inner gel is the part used topically and in food products and is generally considered safe for topical use, though it's worth patch-testing on skin first. The problem is the rest of the plant: the yellowish sap (latex) just under the skin of the leaf, and the leaf skin itself, contain anthraquinone compounds, including aloin, that can irritate bare skin on contact and cause stomach upset if eaten. NC State Extension's own listing warns the plant is poisonous through ingestion or dermatitis, with skin irritation from the latex among the noted symptoms. The ASPCA also lists true aloe (Aloe vera) as toxic to dogs and cats, with vomiting and a change in urine color among the reported signs if a pet chews on it. Keep it out of reach of pets that like to chew on houseplants, and if you're trimming leaves for the gel, rinse the yellow sap off skin and tools before it sits for long or gets near food.
FAQ
How often should I water my aloe vera plant?
There's no fixed interval - water only when the soil is completely dry a couple of inches down, which tends to be roughly every 2-3 weeks in the growing season and less often in winter. Check the soil rather than the calendar.
Why are my aloe vera's leaves turning brown or mushy?
Mushy, translucent leaves or a soft base point to overwatering and root rot. Crispy brown tips without softness are more often mineral buildup from tap water or occasional underwatering.
Can I use the gel straight from the leaf?
Yes, most people do - cut a leaf, split it open, and scoop out the clear inner gel, avoiding the yellow sap layer just under the rind. Patch-test on a small area of skin first since some people react to it.
Is aloe vera dangerous to cats and dogs?
Yes. The ASPCA lists it as toxic to both cats and dogs. Keep the plant out of reach of pets that chew on leaves, and call your vet or the ASPCA Animal Poison Control Center if a pet eats a significant amount.
