Aloe vera is one of the easiest houseplants to keep alive. It stores water in its thick leaves, forgives forgotten waterings, and even gives you free baby plants. Get a few basics right and it can stay healthy for a decade or more.
Meet the Plant
Aloe vera is a succulent that grows in a rosette of thick, pointed leaves with soft teeth along the edges. It is not a cactus. It comes from hot, dry regions, which explains its needs: plenty of sun, fast-draining soil, and very little water.
Its leaves hold a clear gel that people have used for centuries to soothe minor burns and dry skin. Mature plants can send up a tall stalk of yellow or orange flowers in summer, though this is uncommon indoors.
Choosing a Healthy Plant
When buying, look for:
- Plump, upright leaves that feel firm, not soft or floppy
- Fresh green color without brown spots or mushy patches
- Small new leaves growing from the center
- Dry, crumbly soil that smells earthy, not sour
- No pests, such as white cottony fluff or webbing between leaves
A plant with a few baby pups at the base is a good sign of active growth.
Potting and Soil
Drainage matters more than anything else for aloe.
- Pot: Choose a container with drainage holes. Unglazed terracotta is ideal because it lets moisture escape and is heavy enough to keep the plant from tipping.
- Size: Pick a pot only slightly larger than the roots. An oversized pot holds extra wet soil and invites rot.
- Soil: Use a cactus or succulent mix, or make your own by mixing roughly equal parts potting soil and perlite or coarse sand.
- Planting depth: Keep the base of the leaves above the soil so the center of the plant never sits in wet soil.
After potting, wait about a week before the first watering so any damaged roots can settle.
Light
Aloe loves sun. Give it:
- Ideal: Several hours of direct sun each day, such as at an east- or south-facing window
- Acceptable: A bright spot with lots of indirect light
- Avoid: Dim corners, where the plant turns pale, thin, and leggy
If your aloe has been in low light, move it toward the sun gradually. Suddenly moving it into strong sun can scorch the leaves. In very hot summers, a sheer curtain can protect it from harsh afternoon rays.
Watering
Overwatering is the number one killer of aloe.
- Water deeply, but rarely. Let water run through the pot until it drains out.
- Wait until the soil is completely dry before watering again, roughly every two to three weeks in warm months.
- In winter, when growth slows, water much less, perhaps once a month or even less.
- Pour water around the base rather than into the center of the rosette, where it can collect and cause rot.
- Never let the pot sit in a saucer of standing water.
Rule of thumb: when in doubt, don’t water. An aloe can go weeks without water, but soggy soil can kill it quickly.
Temperature and Humidity
Aloe is happy in normal room temperatures, roughly 18–29 °C (65–85 °F), and average household humidity. It does not tolerate frost and dislikes temperatures much below 10–13 °C (50–55 °F). In colder climates, keep it indoors in winter and away from cold drafts.
Feeding
Aloe needs very little fertilizer. A light feeding with a diluted balanced fertilizer once or twice in spring and summer is plenty, and fresh soil every few years often does the job on its own. Too much fertilizer can burn the roots and weaken the plant.
Pruning and Everyday Care
- Remove old, dried outer leaves by pulling them gently downward or cutting them at the base.
- Cut off flower stalks once blooming finishes.
- Wipe dust from the leaves with a damp cloth so the plant can absorb more light.
- Use clean, sharp tools for any cutting.
If you harvest leaves for gel, take only one plump outer leaf at a time from a mature plant, cutting close to the base.
Making New Plants
Aloe multiplies easily through pups, the small offshoots that grow around the mother plant.
- Wait until a pup is a few inches tall with its own roots.
- Gently separate it from the mother plant.
- Let it dry in a shaded spot for a few days so the cut end forms a callus.
- Plant it in dry succulent mix.
- Wait about a week or two before the first watering.
Don’t try to root aloe cuttings in water. They usually rot instead of growing roots.
When to Repot
Repot every two to three years, ideally in spring, or when:
- The pot is crowded with pups
- Roots poke through the drainage holes
- The soil looks old, hard, and pale
- Growth has slowed noticeably
Aloe doesn’t mind being a little crowded, so there’s no rush.
Common Problems and Fixes
| Problem | Likely Cause | What to Do |
|---|---|---|
| Soft, mushy leaves | Overwatering or root rot | Let soil dry out; unpot, trim black roots, and repot in fresh dry mix |
| Wrinkled, thin leaves | Too little water | Soak the pot thoroughly, then resume regular watering |
| Yellow leaves | Watering problems or too much sun | Check soil moisture and light |
| Brown or reddish leaves | Sunburn or heat stress | Filter the light or move back from the window |
| Tall, leaning, pale growth | Not enough light | Move to a brighter spot |
| White cottony patches | Mealybugs | Wipe with an alcohol-soaked swab and treat with neem oil or insecticidal soap |
Persistent orange spots or dark, sunken spots on the leaves can signal a fungal problem. In that case, isolate the plant and remove badly affected leaves. If it keeps spreading, it may be best to start fresh with a healthy plant.
Safety Notes
- Gel on skin: The clear inner gel is generally safe to apply to minor burns, but test a small patch first, since some people react to it.
- The yellow latex just under the leaf skin can irritate the stomach and should not be eaten.
- Pets: Aloe is toxic to cats and dogs if chewed, so keep it out of their reach.
If you have any medical concern, speak with a doctor rather than relying on a houseplant.
Seasonal Cheat Sheet
- Spring and summer: Bright sun, deeper watering every couple of weeks, light feeding if needed
- Fall and winter: Very little water, keep it warm and away from drafts, and maximize whatever light you have
Final Thoughts
Aloe vera rewards neglect better than most plants. Give it bright light, gritty soil, and a pot that drains freely, and water only when the soil has dried out. Do that, and you’ll have a resilient, good-looking plant that also gives you pups to share with friends.
