Our range is large and we supply butterfly protection vegetable cages in many sizes as listed below. The benefit of using a “Build Your Own” brassica cage are that they are supplied in flat-packs and easily built into the frame size you have purchased or combined with another frame to make a larger frame. The build your own butterfly protection frame system allows you to combine frames and you can purchase additional tubes, connectors and woven 7mm butterfly netting as required.

Each frame is made up of either 1m or 1.25m aluminium powder coated tubes which are connected to each other using the “Build-a-Ball” frame connectors. Frames are fixed to the soil using a ground spike inserted into the aluminium tubing of the frame. When the brassica frame is constructed, the 7mm butterfly netting is put over the frame. Fixing pegs are used to keep the netting tight and to stop any gaps between the soil and the inside of the veg cage.
