Tillandsia xerographica is a popular air plant, recognized for its striking, sculptural form. Native to dry tropical regions of Mexico, Guatemala, and El Salvador, it reproduces by producing offsets, commonly known as “pups.” Understanding their development and care allows you to expand your air plant collection.
Understanding Xerographica Pups
Xerographica pups are miniature clones that emerge from the base of the mother plant after it has completed its blooming cycle. This process is the plant’s natural method of reproduction, especially since Tillandsia xerographica blooms only once. Tiny nodes at the plant’s base signal the beginning of pup development.
While some Tillandsia species produce pups within weeks of blooming, Tillandsia xerographica can take several months, or even up to two years, for pups to become noticeable after flowering. The mother plant directs energy towards these offsets, which gradually grow into miniature versions of the adult plant, ensuring the species’ survival as the mother plant senesces.
Caring for Pups While Attached
While pups are attached, consistent care for the entire plant is important. Bright, indirect light is suitable for Tillandsia xerographica, though its silvery leaves and drought tolerance allow it to tolerate more direct sunlight than other air plants. Positioning the plant within 3 to 5 feet of an east or west-facing window is ideal.
Regular watering is also important for the health of the mother plant and developing pups. Soaking the entire plant in room-temperature water for 20 to 30 minutes once a week is a common practice. After soaking, gently shake off excess water and allow the plant to dry completely within four hours to prevent rot, especially since water can collect in its crevices. Good air circulation is important during this drying period.
Separating Xerographica Pups
Separating Tillandsia xerographica pups from the mother plant requires careful timing and technique. Pups are ready for separation when they have grown to at least one-third to one-half the size of the mother plant. Attempting to separate them too early might hinder their ability to thrive independently.
To detach the pups, use a sharp, sterilized knife or garden shears. Position the mother plant on a stable surface and carefully cut the pup away from the base, ensuring to include a small portion of the connecting tissue. Alternatively, if the pup is large enough, it may be gently twisted off by holding both the mother plant and the pup firmly at their bases and applying a slight downward pull.
Caring for Detached Pups
Once separated, Tillandsia xerographica pups require specific care to establish themselves as independent plants. After separation, allow the cut surface on both the pup and the mother plant to dry and harden for a couple of days before watering. This prevents bacterial growth and rot.
Provide pups with bright, indirect light, similar to conditions preferred by mature Tillandsia xerographica plants. Regular watering is necessary, through soaking for 20-30 minutes once a week, ensuring they dry completely afterward. Good air circulation remains important to prevent moisture-related issues. Fertilizing is not needed for the first three months after separation, as young pups are sensitive. These new plants can be displayed on decorative surfaces or mounted to wood.
