A dormant eye is an as-yet inactive bud on a plant from which a new shoot, leaf, or root can emerge under the right conditions. The term originates from fruit growing and horticulture, but is now also frequently used for houseplants when discussing propagation by cuttings. As long as a dormant eye has not been activated, it is usually only visible from the outside as a small, often inconspicuous bump on the stem or at a leaf node.
Unlike an already active eye, from which a shoot is visibly growing, a dormant eye is in a kind of resting phase. The plant only activates it when certain stimuli are triggered – for example, by injury to the stem, exposure to light, moisture, or the removal of apical dominance, i.e., the inhibiting influence of the main shoot tip.
Dormant eye on a Monstera
The dormant eye is particularly well-known in connection with the Monstera, as this plant can be excellently propagated via cuttings with one or more eyes. On a Monstera cutting, the dormant eye is usually located directly at a leaf node, often near an aerial root. If the cutting is cultivated in water, soil, or sphagnum moss, a new shoot can develop from this eye, provided there is sufficient warmth, light, and humidity.
For the successful activation of a dormant eye on a Monstera, the following applies:
- The cutting should have at least one leaf and one visible eye, as no new shoot can emerge without an eye.
- A consistently moist, but not wet, environment promotes activation.
- Warm temperatures between approximately 22 and 26 degrees Celsius and bright, indirect light accelerate the process.
- Patience is crucial, as the activation of a dormant eye can take several weeks to months, depending on the conditions.
Why the dormant eye is important for plant enthusiasts
For anyone who wants to propagate plants themselves, knowledge of dormant eyes is essential. It determines whether a cutting has any potential for a new shoot at all. Anyone who consciously looks for an existing, intact eye when buying or trimming a cutting significantly increases the chances of successful propagation.
