A module (10) for use in a green wall system comprises a box having a base (12) sides (16, 18) a front (20), a rear wall (14) and a top (22). At least some of the side, rear and base define a plurality of relatively small apertures (28), typically of the order of 10 to 30 mm in effective diameter. The front (20) defines a plurality of substantially larger apertures typically of the order of 10 to 12 cm in diameter. In some embodiments, the rear wall or side walls may also define larger diameter apertures. In use, the module (10) may be lined with a permeable geo-textile bag (40) and filled with a planting mix (42). The box is closed using its top (22). The bag (40) is slit through the larger apertures in the front panel and plants (200) are inserted into the mix. Once the plants are established, the module is sandwiched between front (100) and rear (102) U-shaped frames to improve its durability and bolted together using threaded bolts and nuts. The nuts define anchor means for attaching an array of the modules to support rails defining keyhole shaped apertures mounted to a wall. In the array, there are small gaps between the modules so that they can be individually removed form the array and replaced. |
