The Philodendron burle marx is admired for its distinct, variegated foliage, but this characteristic can sometimes diminish, a phenomenon known as “reversion.” Reversion occurs when a variegated plant loses its special coloration, returning to an all-green form. This article explains what reversion entails and how to manage this change.
Understanding Plant Reversion
Variegation stems from a genetic mutation or a chimeric condition, where different genetic cell lines exist within the same plant, resulting in varied tissue appearances. Some plant tissues may lack the ability to produce chlorophyll, leading to white or yellow areas on leaves, contrasting with green tissue.
The green, non-mutated cells in a reverted section contain more chlorophyll, essential for photosynthesis. These green sections are more vigorous and grow faster than the variegated parts, giving them a competitive advantage. If left unchecked, these robust, all-green shoots can eventually outgrow and take over the entire plant, leading to a complete loss of the original variegated pattern.
Common Causes of Reversion
Insufficient light is a primary cause of reversion. Variegated areas of a plant contain less chlorophyll. In low-light conditions, the plant may prioritize chlorophyll production to maximize energy absorption, leading to the development of all-green leaves.
Nutrient imbalances can also play a role, encouraging the plant to revert to a more vigorous, all-green form. Plant age can also influence susceptibility to reversion. Some forms of variegation are inherently unstable, making them more likely to revert regardless of environmental conditions.
Managing Reverted Growth
Managing reverted growth involves identifying affected sections. Reverted sections appear as pure green stems or leaves. These green shoots are more vigorous and can quickly dominate the plant.
The most effective way to manage reverted growth is by pruning. Carefully cut back the all-green sections. Make your cut just below the last variegated leaf on the reverted stem, ensuring you remove the entire green portion.
After pruning, monitor your plant for any new signs of reversion. If a plant has fully reverted, pruning may no longer be effective. At this point, consider accepting the plant’s new all-green form or, if possible, propagating from any remaining variegated parts.
Preventing Future Reversion
Proactive care minimizes the chances of your Philodendron burle marx reverting. Providing optimal light conditions, such as bright, indirect light, helps maintain its variegation. Adequate light ensures the variegated sections can perform photosynthesis effectively, reducing the plant’s need to produce more chlorophyll.
Consistent care practices, including appropriate watering, maintaining suitable humidity levels, and stable temperatures, contribute to plant vigor. A healthy plant is less likely to experience reversion. Balanced fertilization, using a general-purpose houseplant fertilizer, supports healthy growth without promoting excessive green foliage. Regularly inspecting your plant allows for early detection of any emerging green shoots, enabling prompt removal before they become established.
