The Aloe vera plant is widely valued for its dual nature as a resilient houseplant and a source of soothing gel. Its thick, fleshy leaves contain a clear mucilaginous substance used topically for skin irritation and internally as a dietary supplement. Successfully managing this succulent requires understanding two distinct forms of “storage”: the seasonal care needed for the living plant and the preservation methods required for its harvested product.
Storing the Live Plant During Dormancy
The Aloe vera plant enters a natural period of dormancy during the colder months, typically from late fall through winter. This shift requires a corresponding change in environmental conditions to prevent stress or root rot. Maintaining a stable temperature is important, as Aloe vera is susceptible to damage below 50°F, with an ideal indoor range between 55°F and 80°F.
During dormancy, the plant’s metabolic rate slows significantly, reducing its need for water. Watering frequency must be drastically decreased, often to as little as once a month, allowing the potting mix to dry out completely between sessions. Overwatering is the most common cause of plant demise, leading to root rot when the soil remains saturated.
The plant requires bright, indirect light year-round, but its light requirements are less demanding during dormancy. Placing the pot near a south or west-facing window, protected by a sheer curtain, provides sufficient light without risking leaf burn. If the plant has been outdoors, it must be inspected for pests and moved inside before nighttime temperatures fall below the 50°F threshold.
Preparing and Storing Harvested Leaves
When harvesting a leaf for its gel, proper preparation and short-term storage are necessary to maintain freshness and avoid skin irritation. Begin by selecting a thick, mature, outermost leaf and cleanly slicing it near the base using a sharp, sanitized knife. The cut leaf must then be placed upright in a container for 10 to 15 minutes to allow the yellow liquid, known as aloin, to fully drain. This latex-like substance can cause digestive upset or skin sensitivity if not removed.
For short-term preservation, the entire harvested leaf can be stored in the refrigerator, which slows degradation. The cut end should be wrapped tightly in plastic wrap or aluminum foil to seal the wound and prevent moisture loss. A whole, wrapped leaf can be refrigerated for up to one or two weeks, maintaining the integrity of the gel inside. When a portion is needed, a small section can be sliced off, and the remaining cut end should be re-wrapped before returning it to the refrigerator.
Methods for Long-Term Gel Preservation
Once the clear gel is extracted from the leaf, its shelf life is limited unless further preservation steps are taken. The simplest method for long-term storage is freezing the gel in measured portions to halt microbial growth and maintain structural integrity. Using silicone ice cube trays allows the gel to be frozen into convenient, single-use doses that can be easily thawed for application.
These frozen cubes should be transferred to an airtight freezer bag or container once solid and can be stored for six to eight months. Freezing may alter the gel’s texture, causing it to become watery upon thawing, but a quick whisk or blend will restore a usable consistency. If the extracted gel is intended for refrigeration, natural stabilizers must be added to delay oxidation and spoilage.
Vitamin C powder (ascorbic acid) or a few drops of Vitamin E oil can be mixed into the gel to act as an antioxidant. The addition of these stabilizers can extend the refrigerated shelf life of the gel from about one week to two months. Regardless of the method chosen, the container must be airtight and clearly labeled with the date of preparation to ensure the gel is used while still fresh and potent.
