Queen Victoria Agave

The Queen Victoria Agave is drought tolerant and prefers infrequent waterings. The soil should be allowed to dry completely before thoroughly drencching the soil. During the summer months, roughly once every two weeks is appropriate, and during the winter, once every three weeks. Be sure to always check that the soil is dry before watering. Avoid overwatering, as this can lead to root rot and other water-related problems.

This houseplant prefers to bask in bright sunshine in the morning and should be shaded during the mid-afternoon. The Queen Victoria Agave is incredibly sensitive to direct sunlight, so some shade during the hottest parts of the day is beneficial. Though the Queen Victoria Agave strongly prefers bright light, it can still survive and thrive in parts of the home or garden that receive slightly lower levels of light.

The Queen Victoria Agave is very sensitive to fluctuating temperatures and needs warm temperatures between 55-80°F (13-27°C). Cool temperatures can hinder its growth. Make sure to keep the plant away from the direct draft of cold air from any potential sources such as air conditioners, windows, and doors.

This plant requires moderate to high humidity in order to thrive; ideally between 50-70%. Increase humidity in dry climates or environments using a humidifier or pebble tray. Misting the leaves of the plant also helps maintain an optimal humidity level, as well as keeps the leaves hydrated and clean, free of dust.

The Queen Victoria Agave prefers an airy, well-draining mix of potting soil. Avoid a mix that is highly alkaline or acidic, as this can lead to root burn or nutrient deficiencies in the plant. Opt for a combination that includes equal parts of sand, perlite, and organic potting soil.

Fertilizing is optional, however, if desired, apply a balanced cactus fertilizer during the spring and early summer months. Dilute the fertilizer at a rate of only about ¼ of the recommended strength to avoid burning the roots. Avoid applying any fertilizer during the fall and winter months, as there is insufficient light for the plant to adequately utilize the nutrients provided. It is best to use a water-soluble fertilizer, such as a 20-20-20 blend, for best results.

Common pests to watch out for include scale, mealybugs, aphids, and spider mites. These pests can lead to yellowing leaves, water spots, and shriveling leaves. To prevent pest infestations, always properly sanitize the plant's environment before introducing it. To get rid of any pests, remove the affected leaves and spray a commercial insecticide or a home-made insecticidal soap on the plant, followed by rinsing with clean, warm water. Generally, once pests have been removed, the plant should start to recover fairly quickly.

Repotting should be done when the plant has outgrown its pot, showing signs of distress due to lack of space or soil nutrients. This usually occurs every 2-3 years and can be done in the late spring, just as new growth is beginning to emerge. Be sure to select a pot that is slightly larger than the previous; this gives the plant more space for its roots to spread without overcrowding. Select a potting mix that is composed of equal parts of sand, perlite, and organic potting soil.

Queen Victoria Agaves require occasional pruning to maintain their desired shape and size. Using sharp, clean garden shears, prune off dead leaves and any unruly, excessively long leaves. Pruned leaves can be removed from the base of the plant and discarded properly. Pruned leaves can be used for propagation and should be kept in a dry, well-ventilated area until they have reached a desired size for planting.

Mulching can help both retain moisture levels in the soil and prevent weeds from growing in the medium around the plant. A biodegradable mulch such as dried grass clippings or leaves is an excellent choice as it breaks down over time and allows the plant’s root system more access to oxygen and water. Avoid using plastic mulch, as this can lead to root rot.

Propagation can be done by division or by leaf cuttings. To propagate by division, split a mature, healthy clump of Queen Victoria Agave. The root ball should be completely immersed in soil, and the new divisions should be planted in separate containers. To propagate by leaf cutting, cut off a mature, healthy leaf near the base of the plant. Allow the cutting to dry for a few days before inserting it into moist soil. Keep the soil evenly moist and wait several weeks for the roots to start growing.

This houseplant tends to grow straight and upright, without needing any additional support. However, some growers opt to use stakes or trellises to help keep its rosette form upright and strong.

Though not a necessary conditioning for this houseplant, it is beneficial to simulate a rest period for the Queen Victoria Agave at least once a year. During the winter months, decrease both fertilizer and water applications, while also avoiding any direct sunlight during the cooler hours. This helps stimulate the development of strong, healthy leaves and buds once temperatures begin to rise.

The Queen Victoria Agave is not known to be toxic to animals, and its sap is not known to be irritating to human skin. To be safe, it’s best to keep this houseplant away from small pets and children who may be tempted to chew on the pretty, colorful leaves.
