The Monstera Albo captivates with its striking white and green foliage. This distinctive appearance comes from a genetic mutation where parts of the leaves lack chlorophyll, the pigment for green color and photosynthesis. However, owners often see “reversion,” where the plant starts producing all-green leaves, losing its white patterns.
Understanding Reversion
Variegation in Monstera Albo plants arises from a chimera, an organism with cells of different genetic makeups. Reversion occurs when chlorophyll-producing cells outcompete the non-chlorophyll cells, causing a loss of white variegation. This is a natural survival mechanism, as the plant prioritizes green tissue to maximize photosynthesis and energy production.
Common Causes of Reversion
Several factors can influence a Monstera Albo’s tendency to revert. Insufficient light is a common trigger; low-light conditions cause plants to produce more chlorophyll-rich green tissue to maximize photosynthesis, often at the expense of white variegation. Nutrient imbalances, whether deficiency or excess, can also impact variegation stability. The plant’s genetic makeup is a factor, with some individuals being more prone to reversion. Additionally, mature and aging plants may naturally show a greater propensity for reversion.
Identifying Reversion
Recognizing early signs of reversion allows for timely intervention. The primary indicator is the emergence of new leaves that are predominantly or entirely green, with little to no white variegation. Reverted growth typically manifests in fresh foliage. Entire stems may also begin producing only green leaves, indicating a more significant reversion of that section.
Managing a Reverted Plant
Once reversion is identified, action can sometimes encourage the return of variegation. Pruning off all-green stems or leaves is a common practice. This involves cutting back to a node that still shows good variegation, as this indicates potential for future patterned growth. Removing green growth redirects the plant’s energy to variegated sections, potentially encouraging new, patterned leaves.
After pruning, observe new growth to assess the plant’s response. Some plants may continue to revert, and successful re-variegation is not always guaranteed.
Preventing Future Reversion
Maintaining optimal growing conditions is the most effective strategy for preventing future reversion. Provide bright, indirect light, as insufficient light causes variegation to fade. Avoid direct sunlight, as the white, chlorophyll-lacking parts of leaves are susceptible to sunburn. Grow lights can supplement natural light, especially in darker months.
Consistent watering is beneficial; allow the top inch or two of soil to dry between waterings to prevent root rot. High humidity, ideally above 60%, supports plant health and helps maintain variegation. Balanced fertilization during the growing season provides nutrients, but over-fertilization, particularly with nitrogen, may promote excessive green growth. Regular observation allows for early detection of reversion signs, enabling prompt care adjustments.
