This trouble is rarely observed for Tillandsia bulbosa. The growing tip was covered by the bulge at the base of the foliage, and growing leaves can not be expanded. The photograph shows that new leaves are tangling in the basement bulge. Color of leaves in the bulge is pale green because no sun light is illuminated. This trouble will be solved by itself. Encroaching leaves will push and break the bulge. Then leaves turn dark green gradually.
