Build trellis from screed mats yourself
Cheap Rank grid made of screed mats (about 2x1 meter piece about 5.00?) From the building materials trade I use as Rank-Help, for snake cucumbers and runner beans etc.
Make trellis itself - how it works:
First, I use the hammer to drive a fixing rod in the middle of the screed mat. The fixation rod should be stable and about 2 m high after impact. Fix the mat to the bar with wire or cable ties. Put a fixation rod to the right and left of the mat.
This trellis help should be available from both sides for harvesting. Planted with fire beans, the climbing aid is also a nice screen.
