An apparatus secured to extend upwardly from a rooftop for redirecting free oncoming flow of a gas passing over an edge of the rooftop. The apparatus has an elongated member having at least a lower flow-surface, and a leading edge portion having a leading-rim extending therealong. A plurality of supports is spaced along the elongated member. An upper-end of each support is secured to, integrated-with, or otherwise extends from the lower flow-surface of the elongated member. There may be several such elongated members that may be joined. The lower-end of each support extends from the rooftop or sidewall structure to provide a spaced relationship between the lower flow-surface and the rooftop. The leading-rim of the leading edge portion extends into the oncoming flow to redirect of at least a portion thereof so that it flows under the leading edge portion and along the lower flow-surface and, preferably, on into a re-circulation region above the rooftop. A self-deployment mechanism for each support allow for deployment of the apparatus to an operational position upon sufficiently strong gusts.

A method of covering a pot having an upper rim, and containing a floral grouping, comprising: providing a tubular sleeve having an upper end, a closed lower end, a decorative base portion and a tapered portion, the tubular sleeve having a first side, a second side, an outer peripheral surface, an inner peripheral surface, and an inner retaining space surrounded and defined by the inner peripheral surface, the upper end having an edge, the tubular sleeve initially constructed to have a flattened condition and the closed lower end having a gusset therein and the tubular sleeve free of an upper portion sized to surround and encompass the floral grouping disposed within the pot; and opening the tubular sleeve to expose the inner retaining space and disposing the pot and floral grouping contained therein into the inner retaining space. 6. The method of claim 5 wherein, in the step of providing a tubular sleeve, the base portion has a drainage hole therein. 7. The method of claim 5 wherein, in the step of providing a tubular sleeve, the base portion has a ventilation hole therein. 8. The method of claim 5 wherein, in the step of opening the tubular sleeve, at least a portion of the edge of the upper end of the tubular sleeve is positioned near the upper rim of the pot. 9. A method of covering a pot having an upper rim, and containing a floral grouping, comprising: providing a tubular sleeve having an upper end, a closed lower end, a decorative base portion and a tapered portion, the tubular sleeve having a first side, a second side, an outer peripheral surface, an inner peripheral surface, and an inner retaining space surrounded and defined by the inner peripheral surface, the upper end having an edge, the tubular sleeve initially constructed to have a flattened condition and the closed lower end having a horizontal bottom therein in the flattened condition and the tubular sleeve free of an upper portion sized to surround and encompass the floral grouping disposed within the pot; and opening the tubular sleeve to expose the inner retaining space and disposing the pot and floral grouping contained therein into the inner retaining space. 10. The method of claim 9 wherein, in the step of providing a tubular sleeve, the base portion has a drainage hole therein. 11. The method of claim 9 wherein, in the step of providing a tubular sleeve, the base portion has a ventilation hole therein. 12. The method of claim 9 wherein, in the step of opening the tubular sleeve, at least a portion of the edge of the upper end of the tubular sleeve is positioned near the upper rim of the pot. 13. A method of covering a pot having an upper rim, and containing a floral grouping, comprising: providing a tubular sleeve having an upper end, a closed lower end, a decorative base portion and a tapered portion, the tubular sleeve having a first side, a second side, an outer peripheral surface, an inner peripheral surface, and an inner retaining space surrounded and defined by the inner peripheral surface, the upper end having an edge, the tubular sleeve initially constructed to have a flattened condition and the base portion comprising excess material therein for forming a bottom in the closed lower end and the tubular sleeve free of an upper portion sized to surround and encompass the floral grouping disposed within the pot; and opening the tubular sleeve to expose the inner retaining space and disposing the pot therein. 14. The method of claim 13 wherein, in the step of providing a tubular sleeve, the base portion has a drainage hole therein. 15. The method of claim 13 wherein, in the step of providing a tubular sleeve, the base portion has a ventilation hole therein. 16. The method of claim 13 wherein, in the step of opening the tubular sleeve, at least a portion of the edge of the upper end of the tubular sleeve is positioned near the upper rim of the pot. 17.
