A foldable trellis device in accordance with the present invention includes a predetermined trellis configuration having first and second symmetrical portions with substantially similar dimensions and design features. The foldable trellis device further includes pivoting connecting elements to pivotally connect the two portions to allow the two portions to “close” such that front surfaces of respective first and second portions become engaged, or to allow the first and second portions to manually positioned to vertically resist gusting winds. To increase the stability of the foldable trellis device when wind gusts are relatively strong and from varying directions, a stabilizing member is pivotally connected to the first and second portions to form a wind resistant configuration when taking a top elevation view of the foldable trellis device.
