🌱 Aloe Vera

Use a low-drainage, granular, largely mineral substrate to avoid waterlogging and root rot. A cactus/succulent mix amended with coarse sand and/or mineral aggregates (pumice, perlite, slag, lava rock or horticultural gravel) is suitable; avoid heavy clay soils and composts too rich in peat, which retain water. Aim for an open, airy structure with high porosity and good aeration of the root zone. In containers, use a pot with drainage holes and a fast-draining mix; don't leave the plant in water or a saturated saucer. Allow the medium to dry out considerably between waterings. Soil response is best when it is neutral or slightly alkaline (approx. pH 6.5-8).

Aloe vera propagates most reliably from shoots ("pups"); seed sowing is possible but slower and more variable. From shoots (recommended) - Period: spring to early summer (during active growth). - Selection: choose a robust plant with several leaves and its own roots (or visible root initials). Larger plants establish more quickly. - Separation: depot the clump and gently detach the shoot from the parent, retaining as many roots as possible. If cutting is necessary, use a clean, sharp blade. - Callus: leave cut surfaces to dry and callus in a warm, shady, well-ventilated place for around 1-3 days (longer for larger wounds or in humid conditions). - Potting mix: cactus/succulent mix with very low drainage; improve drainage by adding mineral components (pumice, perlite, coarse sand). - Container: small pot with drainage holes; avoid oversized pots, which remain damp. - Planting depth: plant at the same depth as before; keep the crown above the surface and do not bury the leaves. - First watering: wait ~5-7 days after repotting (longer if roots have been damaged), then water lightly. Thereafter, water sparingly, only after the mixture has dried thoroughly. - Establishment: keep plant in bright light, protected from the midday sun, until established; gradually increase sun exposure. From seed (if available) - Seed quality: use fresh seed whenever possible; germination decreases as seed ages. - Timing: sow in warm months, or indoors with background heat and bright light. - Medium: sterile, low-drainage sowing medium (fine cactus mix with added perlite/ponce) in clean pots/trays with drainage. - Sowing: surface sow and bury; cover only with a very thin layer of fine sand. - Conditions: bright light (avoid intense midday sun), heat ~21-27°C, and light air circulation. - Humidity: maintain regular but light humidity, never soggy. Watering from below can reduce the risk of seedling damping-off. - Germination: generally within a few weeks in warm, light conditions. - After germination: once seedlings are large enough to handle, transplant them carefully and pot them individually in a granular succulent mix; gradually acclimatize them to stronger light and drier intervals. Planting and care essentials - Light: bright light in full sun; acclimatize gradually to avoid burning. - Water: "Soak then dry"; reduce watering considerably during cool, low-light periods. - Temperature: protect from frost; for regular growth, maintain temperature above ~10°C. - Outdoor planting (warm climates): plant in raised beds or well-drained soil; avoid heavy/clayey sites unless substantially amended with coarse mineral matter. - Hygiene: remove dead leaves and prevent water from stagnating in the crown to avoid rotting.

Aloe vera feeds very little. Use a balanced cactus/succulent fertilizer containing relatively little nitrogen, or a general houseplant fertilizer diluted 1/4-1/2. Fertilize only during the active growth period (generally spring to summer): apply approximately every 4 to 8 weeks, or limit to 1 or 2 light applications throughout the season. Do not fertilize in autumn/winter or whenever growth is slow (cool temperatures or low light levels). Apply fertilizer to soil that is already moist (water first) and avoid allowing the liquid to penetrate the rosette/crown. Don't apply too much; excess soluble salts can burn roots and leaf tips. Use a fast-draining mix and rinse the pot with clear water from time to time to reduce salt build-up. After repotting in a new mix, wait about 4-6 weeks before fertilizing. For plants established in the open ground, fertilization is generally not necessary; if growth is weak, make a light application in spring, and avoid products with a high nitrogen content, which promote sluggish, weak growth.

Aloe vera inner leaf gel is widely used topically as a skin protector, emollient and moisturizer. It is commonly applied for minor burns (including sunburn), superficial abrasions and mild irritant and contact dermatitis. The results of clinical trials and systematic reviews indicate that aloe vera gel may provide modest symptomatic relief (e.g., reduction in pain, erythema, pruritus) and may shorten the healing time of some superficial or partial-thickness burns and mild inflammatory skin conditions, but results are inconsistent, formulations vary considerably and aloe gel should not replace medical assessment of deep, extensive, infected or non-healing wounds. The bitter yellow exudate from the leaf ("aloe latex"; not the transparent gel) contains anthraquinone glycosides (notably aloin) and is traditionally used orally on a short-term basis as a stimulant laxative in cases of constipation. However, it often causes abdominal cramps and diarrhea and, with repeated or high-dose use, can lead to dehydration and electrolyte disorders (particularly hypokalemia), with potential drug interactions (e.g. with diuretics, cardiac glycosides and other agents affecting potassium levels). Many authorities advise against or restrict the oral use of aloe latex; it should be avoided during pregnancy and breastfeeding, and should not be used on a long-term basis. Topical aloe may also cause irritation or allergic contact dermatitis in sensitive individuals.

Aloe vera is not commonly prepared as a pleasant "tea" from the inner gel; the main traditional use of the oral infusion/decoction is for the latex of the dried leaf ("aloe" medicine), which contains anthraquinone glycosides (notably aloin) that act as a stimulant laxative. Taken as an infusion, aloe latex has been used for short-term relief of occasional constipation by increasing intestinal fluid secretion and stimulating bowel motility. Alleged additional benefits of internal infusion (e.g. digestive soothing, metabolic, "detox" or immune support) are not supported by reliable clinical evidence. Orally administered aloe latex can cause clinically significant adverse effects (abdominal cramps, diarrhoea, dehydration, electrolyte disorders such as hypokalemia) and drug interactions; it is therefore not suitable for chronic use and is generally not recommended, except on medical advice; it is contraindicated during pregnancy and should be avoided in children and in cases of inflammatory bowel disease.

Aloe vera needs light pruning; remove only dead, damaged or diseased outer leaves. Use a clean, sharp knife or pruning shears and cut the leaf as close as possible to the base/crown without injuring the central growth point. Do not trim leaf tips for aesthetic reasons (this leaves permanent brown edges); instead, remove the whole leaf if necessary. Prune during the active growth period (spring-summer) so that wounds heal more quickly. If the plant is crowded, separate and remove offshoots by cutting them off at the base with some roots attached; allow the cut surfaces to dry and heal for 1 to 3 days before potting or resuming more abundant watering. Disinfect tools between cuts, and avoid getting sap on your skin or eyes.
