The present invention describes a method of covering a flower pot with an oversized sleeve, as well as a plant package formed therefrom. The sleeve has an inner diameter which is greater than the maximum diameter of a pot disposed therein. The sleeve may have a detachable upper portion, a skirt portion with a linear or non-linear upper end, or with or without gussets in the lower end or sides. The sleeve may be secured about the pot by crimping a portion of the sleeve having a bonding material thereon, or by using a securing element.
