ABSTRACT:
A retractable greenhouse canopy apparatus (10) including a support mechanism (22) pivotably mounted to the ground beside a greenhouse (12) for extending above but not fully across the greenhouse. The support mechanism includes a first portion (23) extending upwardly from the ground and a second portion hingedly attached to the distal end of said first portion. An insulated blanket (14) is supported by the support mechanism and includes a first portion (54) for covering a section of the greenhouse beneath the support mechanism and a second portion (56) for covering a section of the greenhouse beneath the second portion of the support mechanism. The second portion of the support mechanism is folded relative to the first portion of the support mechanism and the support mechanism is pivotably raised to retract the blanket sufficiently to expose a previously covered region of the greenhouse and the second portion of the support mechanism is unfolded relative to the first portion of the support mechanism and the support mechanism is pivotably lowered to extend the blanket and cover the exposed region of the greenhouse.
