How to build a tomato string supports

Instead of canes, each plant climbs a string hung from above. It's cheap, quick and perfect in a greenhouse or over growbags, where canes won't go in deep.

Tools

Step by step

  1. In a greenhouse, skip to step 2. Outdoors, hammer in two stakes 2.4m apart behind your plants, then screw the batten across the top.
  2. Tie a string to the bar above where each plant will go, long enough to reach the ground.
  3. Plant the tomato. Tie a loose loop of the string round the bottom of the stem, under the lowest leaves - or bury the end under the rootball.
  4. Once a week, gently twist the top of the plant round the string - once round every few leaves - so it climbs it.
