Sodate
On this page
Aloe vera needs a genuinely bright spot — a south or west window — gritty succulent mix, and water only when the soil is fully dry (every 2-3 weeks). It multiplies via pups, so one plant becomes many. The gel is soothing on skin, but the yellow latex beneath the skin is a purgative: mildly toxic to cats and dogs, and the reason you shouldn't eat home-prepared leaves. $5-$25.
Key facts
- Cultivated for so long (documented in Egypt over 3,500 years ago) that its wild origin is uncertain — likely the Arabian Peninsula; it now grows worldwide in warm climates.
- The clear inner gel is roughly 99% water and is the part used on minor burns and sunburn.
- The yellow latex (aloin) just under the leaf skin is a strong laxative — this is what makes aloe mildly toxic to cats and dogs, causing vomiting and diarrhea if chewed.
- Produces offsets (pups) freely: a healthy plant surrounds itself with babies you can pot up.
Care requirements#
| Plant type | Indoor / outdoor (year-round outdoors in USDA 9-11) |
| Growing medium | Gritty, fast-draining cactus/succulent mix |
| Light needs | Bright light with some direct sun — a south or west window; acclimate gradually to harsh summer sun |
| Water frequency | Every 2-3 weeks; soak thoroughly, then wait until the soil is completely dry |
| Humidity | Low; dry household air is ideal |
| Temperature range | 18-27°C (65-80°F); protect below 10°C (50°F); frost destroys the water-filled leaves |
| Fertilizer | Diluted succulent feed 2-3 times in spring-summer at most |
| Soil pH | 6.0-8.0 (unfussy) |
| Drainage needs | Very high — the number one care factor |
| Pot recommendation | Terracotta with a drainage hole, wide rather than deep (aloe roots are shallow) |
| Harvesting gel | Cut an outer leaf at the base, stand it upright 10 minutes to drain the yellow latex, then fillet out the clear gel |
| Toxicity | Mildly toxic to cats and dogs (aloin latex); gel is used topically on human skin |
Growth & propagation#
| Mature size | 30-60cm rosette indoors; larger in the ground |
| Growth rate | Moderate for a succulent — several new leaves a year in good sun |
| Propagation methods | Pups (offsets) around the base; leaf cuttings generally fail because of the high water content |
| Propagation difficulty | Very easy via pups — cut away with some roots and pot up |
| Repotting schedule | Every 2-3 years, or when pups crowd the pot or the plant gets top-heavy |
| Pruning needs | None — harvest or remove outer leaves at the base as needed; leaves don't grow back once cut |
Common problems & troubleshooting#
| Symptom | Likely cause | Fix |
|---|---|---|
| Mushy, water-soaked leaves collapsing at the base | Overwatering and root rot — the classic aloe killer | Unpot, cut away rotted roots and leaves, let the plant dry callous for a day or two, repot in dry gritty mix |
| Thin, curled, dull leaves | Long-term underwatering — the plant is consuming its own water reserves | Water deeply; leaves plump up over a week or two |
| Flat, pale, stretched growth leaning to the light | Not enough sun (etiolation) | Move to a south or west window gradually; new growth comes in compact |
| Leaves turning brown-red overall | Sun stress — often after a sudden move into harsh direct summer sun | Usually harmless stress colouring; shift to slightly less intense light and it greens up |
| Brown, dry, sunken spots after a cold night | Chill or frost damage to the water-filled tissue | Keep above 10°C; trim destroyed leaves at the base — they won't recover |
Drought-built, drowning-prone
Sodate waits until your aloe's soil has fully dried before nudging you — because watering too often is the only way most people kill one.
Seasonal care#
Varieties & cultivars#
| Variety | Distinguishing trait | Note |
|---|---|---|
| Aloe vera var. chinensis | Smaller, spotted form common in the houseplant trade | Often sold as plain aloe vera; keeps white spots into adulthood |
| Aloe 'Minibelle' | Compact hybrid with heavily spotted slender leaves | Windowsill-sized |
| Aloe barbadensis 'Miller' | The thick-leaved commercial gel-production strain | The name you'll see on cosmetic labels |
Buying checklist#
- Leaves are fat, firm, and upright — thin or floppy leaves mean stress
- Grey-green colour is normal; deep green with soft spots suggests overwatering
- Base of the plant is dry and firm, with no dark mushiness at the soil line
- Pups around the base are a bonus (free plants)
- Plant sits stable in its pot — a wobbly aloe often has a rotted root system
Pricing by region#

Often confused with#
Name confusion warning#
Not everything sold as "aloe" is Aloe vera. Shops mislabel haworthias, gasterias, and ornamental aloes as aloe vera. If you want the medicinal gel plant, look for thick, grey-green upright leaves — and never use gel from an unidentified lookalike on skin.
Where it's actually grown#
Potted aloe vera is mass-propagated from pups in succulent nurseries in Florida, California, Spain, and across Asia, while commercial gel comes from irrigated field plantations in Mexico, the Dominican Republic, Texas, and India — the two supply chains are entirely separate.
Import & biosecurity restrictions#
| Region | Note |
|---|---|
| Australia | Live plant imports restricted under biosecurity law; abundantly grown domestically. |
| US | Domestic sale unrestricted; hardy outdoors in the far south and southwest. |
| UK | No restriction; strictly indoors except in the mildest coastal spots. |
| India | No restriction; grown commercially at farm scale (notably in Rajasthan and Gujarat) and sold everywhere. |
| Canada | CFIA permits for commercial imports; a windowsill plant only. |

Frequently asked questions
Is aloe vera toxic to cats and dogs?
Mildly, yes. The yellow latex under the leaf skin contains aloin, a purgative that causes vomiting and diarrhea if pets chew the leaves. It's rarely dangerous, but keep it out of reach of chewers.
How often should I water aloe vera?
Every 2-3 weeks — soak it thoroughly, then wait until the soil is completely dry. In winter, once a month is plenty.
Can I use the gel straight from the plant?
For minor burns and skin irritation, yes: cut an outer leaf, stand it upright to drain the yellow latex, then use the clear inner gel. Don't eat home-prepared leaves — the latex layer is a strong laxative.
Why is my aloe floppy and thin?
Usually not enough light. Aloe needs real sun; in a dim corner the leaves stretch, flatten, and flop. A south or west window fixes new growth.
What do I do with the babies around my aloe?
Those pups are free plants. Once they're a few centimetres tall, cut them away with some roots at repotting time, let them dry a day, and pot them in succulent mix.
