A unique disposable and collapsible nursery container for trees and shrubs is comprised of an outer plastic film bag and an inner bendable sheet of expanded polystyrene. The invention overcomes numerous problems which currently exist in the marketplace. In particular, the expanded polystyrene sheet is coated on the inside with a root pruning compound which prevents excessive root ball formation. In addition, expanded polystyrene has insulating qualities which protect the roots from excessive cold or excessive heating caused by exposure to sunlight. The present invention can be shipped and handled in a collapsed state thereby creating savings in storage and transportation. |
