What Do Aloe Plants Need to Stay Healthy?

The Aloe vera plant is a well-loved houseplant recognized for its thick, fleshy leaves that store a soothing, clear gel. This succulent is native to arid climates, giving it natural resilience and capacity to withstand drought. Its popularity stems from its hardiness and purported medicinal uses, making it an excellent choice for indoor gardening. To maintain plump leaves and healthy growth, replicating its native dry, bright environment is the primary objective of proper care.

Light and Sun Exposure

Aloe vera thrives with bright, indirect sunlight for six or more hours daily. Placing the plant near a south or west-facing window is often ideal. However, intense, direct sun passing through glass can scorch the leaves, causing brown or bleached patches. The light should be filtered or diffused to prevent this sunburn, which damages the water-storing cells.

The plant communicates its light needs through its appearance. Insufficient light causes the leaves to stretch and lean toward the light source, a process called etiolation, resulting in weak, pale growth. Conversely, too much direct sun may cause the aloe to turn a reddish-brown or yellow color as a stress response, indicating it needs a shadier spot. A healthy plant maintains a compact, vibrant green rosette of firm leaves.

Proper Watering Techniques

Improper watering is the most common cause of decline for indoor Aloe vera plants. Since the leaves hold large reserves of water, the plant does not tolerate consistently wet roots, which quickly leads to fungal root rot. The fundamental technique is the “soak and dry” method: thoroughly saturate the soil until water flows from the drainage hole, then allow the soil to dry out completely.

Before rewatering, confirm the top two inches of the potting medium are entirely dry, usually by inserting a finger into the soil. This typically translates to watering every two to three weeks during the spring and summer active growing season. Watering frequency must be reduced during the cooler fall and winter months, potentially only once a month or less. If the leaves appear thin, curled, or shriveled, the plant is dehydrated and needs a thorough soak.

Soil Composition and Drainage

The root system requires a highly porous and aerated planting medium to facilitate rapid drying between waterings. Standard all-purpose potting soil is too dense and retains excessive moisture, making it unsuitable for this succulent. Instead, use a specialized cactus or succulent mix. Another element is amending regular potting soil with coarse sand, perlite, or pumice to improve drainage.

The substrate should mimic the sandy, gritty soil of its native habitat, allowing water to pass through quickly and prevent waterlogging. Selecting a container with a drainage hole is necessary to allow excess water to escape immediately after soaking. Unglazed terracotta pots are often preferred over plastic because their porous material wicks moisture away from the soil, helping the root zone dry faster.

Temperature Control and Feeding

The plant thrives in the comfortable temperature range preferred by humans, ideally between 65°F and 75°F. While Aloe vera tolerates warm conditions, it is highly sensitive to cold and must be protected from temperatures dropping below 50°F. Keeping the plant away from cold drafts near windows or air conditioning vents during winter prevents cold stress.

As a species adapted to nutritionally poor desert soils, Aloe vera has very low nutrient requirements compared to other houseplants. Fertilization is not necessary for survival, but a light feeding supports robust growth during the spring and summer months. If feeding, use a balanced houseplant fertilizer diluted to half or quarter strength, applying it only once or twice during the active growing season. The plant should receive no fertilizer during its rest period in the fall and winter.
