Abstract: Protective container, especially adapted for vines, is provided with a sleeve comprising two semi-shells adapted to envelope a plant. A journal connects the two semi-shells and a latching element maintains the two semi-shells in a closed positioned so that the sleeve has a general shape of a tube open at both ends. The sleeve is sufficiently rigid so as to act as a support, and includes a lower portion adapted to be at least partially buried and envelope a root system of a plant, an upper portion constructed and arranged to enable free access therein, and an intermediate tubular portion, having reduced dimensions and reinforced mechanical resistance, separating the lower and upper portions. Projections in the general shape of teeth of a comb extend from the lower end of the lower portion to retain the root system of the plant and a substrate. The upper portion includes an openable portion which is selectably closable.
