The Alocasia macrorrhizos ‘Flying Squid’ is a dwarf cultivar known for its unusual morphology. A mutation of Alocasia macrorrhizos ‘Plumbea’, this plant features long, slender petioles that dominate its appearance. The actual leaf blade is reduced to a tiny, spear-like structure at the petiole’s tip. This sculptural form strongly resembles squid tentacles, giving the plant its common name and making it a prized addition for Aroid collectors.
Ideal Environmental Conditions
The Alocasia ‘Flying Squid’ requires bright, indirect light to thrive and maintain its upright growth habit, mirroring its tropical forest origins. Placing it near an east-facing window or a few feet away from a well-lit south or west window typically offers sufficient illumination. Direct midday sun must be avoided, as the specialized, thin petioles and vestigial leaf blades can easily scorch or suffer from dehydration under intense, unfiltered light.
Temperature stability is important for the successful cultivation of this tropical Aroid. The plant prefers consistent warmth, with ideal temperatures ranging between 65°F and 80°F (18°C and 27°C). Exposure to temperatures below 60°F (15°C) can cause stress and potentially trigger the plant into an unwanted dormancy. Cold drafts from windows or air conditioning units should be avoided entirely.
High ambient humidity is particularly important, often exceeding 60% relative humidity. Insufficient moisture in the air can lead to browning or crisping along the edges of the tiny leaf blades and petiole tips. Utilizing a dedicated room humidifier is the most effective way to meet the plant’s moisture demands, especially in drier indoor environments. Grouping the plant closely with other moisture-loving plants can also create a beneficial microclimate.
Substrate Requirements and Watering Strategy
The choice of growing medium directly impacts the health of the rhizomatous root system, which is highly susceptible to rot. Standard, dense potting soil is unsuitable because it retains too much moisture and restricts essential oxygen flow. The plant requires an airy, well-draining, and chunky substrate, often referred to as an “aroid mix.”
An effective substrate uses components like orchid bark, perlite or pumice, and coco coir. This porous composition allows for rapid drainage while still holding enough moisture to satisfy the plant’s needs. The chunky nature of the mix prevents the waterlogged conditions that are detrimental to the underground corms.
Watering involves thoroughly saturating the substrate and then allowing the top one to two inches of the mix to dry out before watering again. Apply water until it drains freely from the pot’s drainage holes, ensuring the entire root ball is hydrated. Discard any water that collects in the saucer after 15 minutes to prevent the roots from sitting in stagnant moisture. Watering frequency must be significantly reduced during the cooler winter months when the plant’s metabolic rate slows down.
Seasonal Maintenance and Feeding
Routine maintenance for the Alocasia ‘Flying Squid’ includes providing regular nutrients and managing its growth cycle, which often involves a period of rest. During the active growing season, typically spring through early fall, the plant benefits from monthly applications of a balanced liquid houseplant fertilizer. This fertilizer should be diluted to half or quarter strength to prevent nutrient burn on the sensitive roots.
Fertilization should be completely suspended in the late fall and winter months, aligning with the plant’s natural tendency toward dormancy. Repotting is generally necessary only when the plant becomes visibly root-bound, which usually occurs every one to two years. When repotting, select a container that is only one size, or about 1 to 2 inches, larger in diameter than the previous one to avoid excessive soil volume that could lead to overwatering issues.
Dormancy is a natural, protective mechanism in many Alocasia species, often triggered by lower light levels or cooler temperatures. Signs of the onset of dormancy include a marked slowing of growth and the yellowing and dropping of older petioles. If the plant enters this resting phase, all above-ground growth may die back completely, leaving only the underground storage corm. During this time, dramatically reduce watering to just a minimal amount to prevent the corm from completely desiccating, and withhold all fertilizer until new growth resumes in the spring.
Propagation Methods and Troubleshooting Common Issues
Propagation Methods
The most reliable method for propagating the Alocasia ‘Flying Squid’ involves the division of its underground corms or the separation of offsets. Alocasia plants produce small, bulb-like structures called cormels, which are miniature versions of the main corm found nestled among the roots. These cormels can be gently twisted or cut away from the mother plant using a sterilized blade during the spring repotting process.
Plant each separated cormel in its own small pot filled with the standard airy aroid mix. Keeping newly potted cormels in a warm, high-humidity environment greatly improves the chances of successful sprouting and establishment. This division method ensures that the new plantlets possess the exact genetic characteristics of the parent plant.
Troubleshooting Common Issues
Several issues can arise, often stemming from environmental factors, with yellowing leaves being a frequent symptom. Yellowing of older, lower petioles often indicates overwatering and subsequent root stress, especially if the soil mix is too dense or the watering schedule is too frequent. Conversely, yellowing or drooping can also signify severe underwatering, which is why checking the soil moisture before watering is so important.
Pests like spider mites are a common problem for Alocasia species, which thrive in the same low-humidity conditions that cause leaf crisping. These pests are identifiable by fine webbing and tiny specks on the petioles and leaf undersides, and they can be managed with regular applications of horticultural oil or insecticidal soap. Fungal issues, such as leaf spot, are less common but can occur in conditions of poor air circulation combined with high humidity, making gentle air movement around the plant a beneficial preventive measure.
