Aloe Humilis (Spider Aloe) – How to Grow and Care Guide

Succulent fans, Aloe humilis—the spider aloe—is a stunning addition to your indoor collection! This easy-care succulent will enhance any area. This site explains how to grow and maintain this lovely plant.

Aloe Humilis (Spider Aloe)

Spider Aloe, a low-growing succulent native to South Africa’s northern Great Karoo, is Aloe humilis. It has amazing rosettes of broad and incurved greyish-green leaves with reddish spots and tall flowering spikes. This intriguing plant needs bright light and well-drained soil to thrive in USDA zones 9-11.

Given its long bloom cycles, Aloe humilis can grow 3 feet tall and 3 feet broad outdoors. Indoors, this plant will likely stay under 2 feet tall.

The Spider Aloe can handle more moisture than most ornamental aloes, causing neophyte gardeners to believe that aloes need little water. This plant needs a lot of water in summer, therefore keep it in full sun and dry. Don’t worry about pests or diseases attacking your spider aloe, no matter where you display it!

While studying, we found that some South African cultures treat cuts by spreading Spider Aloe stem juice on the wound, which not only heals but also gives any area a unique, easy-care aesthetic!

Aloe Humilis Care

Spider aloe is a beautiful, low-growing succulent. South African native, it thrives in warm areas and can withstand frigid conditions. Aloe humilis needs light and well-drained soil. Extreme wetness causes root rot in most aloes.

This species can grow two feet tall and one foot wide under ideal conditions. Aloes have broad, spindly leaves with delicate yellow-green hue and mottled patterns or blazing red tips from bright light exposure. A shallow root system produces rosettes with deeply grooved stems. If grown in full sun, small yellow flowers develop on tall spikes above the foliage in mid- to late April.

Aloe humilis needs good drainage and mild temperatures throughout the growing season (60 to 90 degrees Fahrenheit). Overwatering promotes rot, powdery mildew, and botrytis rot. Many growers prefer to water this plant directly onto the roots, however if frost has been a problem in your area, decrease watering after winter till spring.

Fertilize lightly in early spring using low-nitrogen cactus/succulent food mixes from garden centers or online vendors to avoid overwatering soil during peak summer evaporation. Spider aloes grow best outside year-round from established individuals planted on permanent sites in full sun with periods of bright shade. Bring them indoors for winter protection if temperatures drop below 30 degrees Fahrenheit.


The clump-forming species grows to 6″ tall and 3′ broad. Blooms for months. Star-shaped, yellow flowers can also be orange or pink.

Soil And Transplanting

Cactus mix dirt helps spider aloe drain. Root rot can result from overwatering. Growing spider plants outdoors in USDA Hardiness Zones 9b–11b is easy. Indoors, grow in bright light but not direct sunlight at 65°–80° F (18°–27° C). Aloe humilis loves to be re-potted every two or three years with well-draining cactus mix at the same level.

Flowering and Fragrance

Aloe humilis is mainly grown for its ornamental value, rather than for fragrant flowers. This succulent can flower throughout the year, but it’s more likely to produce blooms in summer and fall when outdoor temperatures are milder. The star-shaped flower heads contain many small yellow or orange blooms, and will sit just above the foliage on thin stems. These blooms are quite small and have no fragrance, yet still make up a floral display that is sure to be admired! When planting in pots, it’s best to choose one with good drainage holes – spider aloe’s roots need plenty of oxygen.

Light and Temperature

Aloe humilis prefers bright light but may handle medium light and should not be in direct sun for more than two hours per day. Outdoors, pick a position with some noon sun protection. To illuminate it, place it near a south or west-facing window. Expect slow growth and fewer blossoms with little light.

Warm temperatures—65°F–80°F (18°C–26°C)—are ideal for Spider Aloe growth. In USDA hardiness zones 9b–11, Aloe humilis can survive outdoors year-round with protection. Aloe needs 40°F–50°F (5°C–10°C) temperatures to endure cooler weather. Freezing temperatures or 40°F will harm these succulents.

Watering and Fertilizer

Aloe humilis needs to be watered every two or three weeks in summer and once a month in winter to avoid drying up. Mulch and gravel protect plants from light frosts and retain moisture during warm weather. Feed Aloe humilis diluted liquid fertilizer with an NPK ratio of 8-8-8 or 10-10-10 every few months during the growing season. To avoid root burn, water before and after feeding to distribute nutrients.

Grooming & Maintenance

Aloe humilis care is simple and beneficial. Pruning is the only task, but it’s one of the best for your plant. Since spring and summer are excellent growing seasons, prune and groom.

Remove dead and damaged leaves first. Trimming spent stems and wilting blooms ensures optimum growth and maintains the Aloe at its best! Trim the plant using sharp shears or scissors. Use tip pruning or selective thinning to make your young Spider Aloe erect with a central leader.

Grooming also keeps plant tissues hydrated. This reduces summer moisture stress and improves growth. Make sure no old leaves from uprooted plants touch other plants when brushing or combing them out. This could spread pests or diseases. Finally, regularly remove fallen leaves to avoid mulching material buildup on the soil surface, which can cause root rot.

Aloe Humilis Propagation

Aloe humilis is a low-growing succulent with orange-yellow spring and summer flowers. If watered and lit, they can bloom again in summer. Offsets or base leaf cuttings spread Aloe humilis readily. Cut an offset at the base without damaging the parent plant. A mature leaf can be cut off with sharp scissors or a clean blade close to the root and left to grow calluses before planting in fresh soil. Single leaves can be rooted by placing them on standard soil medium, covering them with another thin layer of soil, and keeping the top moist until new roots emerge. This applies to all Aloes because they propagate similarly.

Aloe Humilis Uses and Diseases

Aloe humilis, sometimes known as spider aloe, is a Karoo succulent shrub. This succulent grows quickly and requires minimal care. Containers and rock gardens benefit from spider aloe’s thick, meaty or waxy leaves. It blooms from October to early summer with racemes of yellow or orange flowers.

Offsets are the most popular means to propagate spider aloe, however seedlings can also be used. Seed-grown Aloe humilis may not be true to type. Choose healthy offsets from a parent plant you like for optimal results.

Aloe humilis is beautiful and useful! When used topically to small burns, rashes, or insect bites, the leaves’ gel-like material heals, and drinking its extract can help stomach disorders including indigestion and irritable bowel syndrome (IBS). The extract can nourish skin with amino acids, minerals, and Vitamins C & A as a shampoo or face wash.

Spider aloes are resilient plants that need minimal care, but drought-like weather or insufficient irrigation during warmer months can pose issues. Spider aloes are also susceptible to root and crown rot due to excessive moisture at their roots, so it’s crucial to give them proper air circulation and monitor soil wetness regularly. When fertilizing Aloe humilis, use low doses of vitamins B9 and A, which enhance development if not abused!

Aloe humilis growth and toxicity

Aloe humilis grows slowly to around 8 inches (20 cm) tall and 16 inches (40 cm) wide (40 cm). Late winter and spring flower spikes grow over its succulent rosettes.

Non-toxic aloe humilis. Aloe humilis is safe for pets and children, unlike other aloes. Avoid touching the gel in the leaves since direct contact with the sap can irritate certain people.
