The Echeveria ‘Perle von Nurnberg’ is a popular succulent, known for its striking rosette form and captivating blue-gray, pink, and purple hues. This hybrid is a favorite among plant enthusiasts due to its visual appeal and straightforward care. While generally easy to maintain, a common concern is when the ‘Perle von Nurnberg’ begins to elongate or “grow tall.” This article explores the reasons for this stretching and provides practical solutions.
Understanding Etiolation in Echeveria Perle von Nurnberg
When an Echeveria ‘Perle von Nurnberg’ grows tall, it is experiencing etiolation, a condition caused by insufficient light. The plant stretches to find a more adequate light source, resulting in an elongated stem with widely spaced leaves, departing from its natural compact rosette form.
When etiolation occurs, the ‘Perle von Nurnberg’ loses its characteristic short, dense structure. Its stem becomes visibly stretched, and the leaves, once tightly clustered, spread out, creating a sparse, leggy appearance. This stretching is not a sign of healthy development but rather indicates the plant is actively seeking more light. Once a succulent has etiolated, it will not revert to its original compact form without intervention.
Preventing Leggy Growth
Providing sufficient light is the most effective measure to prevent leggy growth. Echeveria ‘Perle von Nurnberg’ thrives in bright, direct sunlight, ideally receiving at least six hours daily to maintain vibrant coloration and compact shape. For indoor plants, a south-facing window is recommended, offering the most intense natural light. Rotating the pot periodically ensures all sides receive adequate light, preventing uneven stretching.
When natural light is limited, supplemental grow lights are highly beneficial. Full-spectrum LED grow lights provide the necessary intensity to prevent etiolation. Position the grow light within a few inches of the plant for effectiveness without causing burns. Consistent light exposure helps the plant maintain its characteristic tight rosette.
Watering practices also play a role in preventing leggy growth. Overwatering, especially with low light, can exacerbate stretching. Follow the “soak and dry” method, watering thoroughly only when the soil has completely dried out. This mimics the dry conditions succulents experience naturally.
Approach fertilizer application with caution. Excessive nitrogen promotes rapid, leggy growth instead of the desired compact form. Use a balanced succulent fertilizer, diluted to half or quarter strength, sparingly during the active growing season (spring and summer). This supports healthy development without encouraging unwanted stretching.
Correcting an Etiolated Echeveria
Correcting a leggy Echeveria ‘Perle von Nurnberg’ involves “beheading,” a technique that allows the plant to restart compact growth. Use a clean, sharp knife or scissors to cut the stem just below a healthy rosette of leaves, leaving a few inches of stem attached.
After cutting, both the severed rosette and remaining stem require a callusing period. Allow cut surfaces to dry and form a protective scab for two to five days. This callusing prevents rot when reintroduced to moisture. Place cut pieces in a dry, well-ventilated area away from direct sunlight.
Once the rosette’s cut surface has callused, replant it into fresh, well-draining succulent soil. Create a small hole, insert the callused stem, and ensure the rosette sits firmly. Provide immediate bright light to prevent re-etiolation. New roots typically form within a few weeks.
The remaining “mother stem” in the original pot can produce new offsets along its length. Continue caring for this stem as a mature plant; new rosettes will emerge, contributing to a bushier plant. Healthy leaves removed during beheading can also be propagated. Once callused, lay these leaves on well-draining soil to sprout roots and tiny new rosettes.
