Aloe Vera

Aloe vera · also called true aloe, medicinal aloe, burn plant

Aloe vera is a hardy succulent with fleshy, gel-filled leaves prized for soothing burns. It needs bright light and infrequent, deep watering.

Aloe vera is a clumping succulent with thick, fleshy, gray-green leaves edged with soft teeth, forming a rosette that can reach a foot or two across. The leaves are filled with a clear gel long used to soothe minor burns and skin irritation, making aloe both a decorative and a practical windowsill plant.

Adapted to hot, arid climates, aloe stores water in its leaves and thrives on neglect, asking mainly for strong light and well-draining soil. The most common way to harm it is overwatering, which rots the base and roots. With enough sun, mature plants produce offsets, or pups, around the base that can be separated into new plants.

How to care for Aloe Vera

Light

Aloe vera needs bright light and does best with several hours of direct sun, such as a south or west window. Too little light causes pale, stretched, floppy leaves. Acclimate it gradually to strong sun to avoid scorching the leaves brown or red.

Watering

Water deeply but infrequently, letting the soil dry out completely first, roughly every 2 to 3 weeks and even less in winter. Soak the soil thoroughly, then let all excess drain away. Overwatering is the fastest way to kill aloe, so err on the dry side.

Humidity

Aloe vera prefers dry air and tolerates the low humidity of most homes easily. No misting or humidifier is needed. High humidity combined with wet soil increases the risk of rot.

Temperature

Keep it between 55 and 80F. It enjoys warmth and can summer outdoors, but it is not frost-hardy and should be protected below 50F. Move it indoors well before the first cold snap.

Soil & potting mix

Use a fast-draining cactus and succulent mix, or amend regular potting soil with plenty of perlite, pumice, or coarse sand. Sharp drainage is essential to prevent root rot. A terracotta pot with drainage holes helps the soil dry faster.

Feeding

Feed sparingly, only once or twice during spring and summer, with a diluted cactus or succulent fertilizer. Aloe needs very little feeding and can be harmed by excess. Do not fertilize in fall or winter.

Pruning & grooming

Remove any shriveled, dead, or damaged leaves by cutting them at the base with a clean knife. Harvest gel from outer mature leaves as needed. There is otherwise little pruning required.

Repotting

Repot every 2 to 3 years or when offsets crowd the pot. Move up one pot size and refresh the gritty mix in spring. Let the plant settle a few days before watering to let any disturbed roots heal.

Propagation

Propagate by separating the pups that grow around the base, each with some roots, and potting them in dry succulent mix. Let any cut surfaces callus for a day before planting. Leaf cuttings rarely root and usually just rot.

Common Aloe Vera problems

  • Mushy, translucent leaves. Soft, water-logged leaves signal overwatering and rot. Stop watering immediately, let the soil dry fully, and repot into gritty, fast-draining mix if the base feels soft, trimming away any rotted tissue.
  • Pale, stretched leaves. Leaves that grow thin, pale, and floppy and flop outward are reaching for light. Move the plant to a sunnier spot with several hours of direct sun to restore compact, upright growth.
  • Brown or red leaves. Leaves turning reddish-brown often mean sunburn from too-sudden intense light, or stress from underwatering. Acclimate the plant to strong sun gradually and water deeply when the soil is fully dry.
Toxicity: Toxic to cats and dogs. The latex layer just beneath the leaf skin contains saponins and anthraquinones that cause vomiting, diarrhea, and lethargy if eaten.

Diagnose a problem

How to Identify and Fix Root RotRoot rot is caused by overwatering and poor drainage, which suffocate the roots and let fungus take hold. Caught early, most plants can be saved by trimming rot and repotting dry.Signs of Overwatering and How to Fix ItOverwatering suffocates roots in soggy soil, causing yellowing, soft leaves, and eventually root rot. The fix is to let the soil dry, improve drainage, and water by feel instead of a schedule.Why Is My Plant Leaning and Stretching Toward the Window?A plant that leans, bends, or stretches toward the window is reaching for more light, a behavior called phototropism. Here is why it happens and how to keep your plant growing straight.

Aloe Vera FAQ

How often should I water aloe vera?

Water aloe vera only when the soil has dried out completely, which is usually every 2 to 3 weeks in the growing season and even less in winter. When you do water, soak the soil thoroughly and let all the excess drain away. Because aloe stores water in its leaves, overwatering is far more dangerous than letting it go dry.

Why are my aloe vera leaves turning mushy or brown?

Mushy, translucent leaves are a sign of overwatering and root or base rot, so let the soil dry out and repot into gritty mix if the base feels soft. Brown or reddish leaves, by contrast, usually mean sunburn from too much sudden direct sun or stress from going too dry. Match the cause to the symptom before adjusting care.

Is aloe vera safe for pets?

No, aloe vera is toxic to cats and dogs. The latex layer just under the leaf skin contains compounds that can cause vomiting, diarrhea, and lethargy if a pet eats the plant. Keep aloe well out of reach of curious cats and dogs, ideally on a high sunny shelf.
