Plant techniques

Support tomatoes and identify side shoots

Check the label: indeterminate tomatoes are usually trained as cordons; determinate bush varieties keep their branching growth.

When to do it

Install support at planting and inspect during active growth.

What you need

  • Variety label
  • Suitable stake, cage or trellis
  • Soft ties and clean snips

How to do it

  1. Check the label: indeterminate tomatoes are usually trained as cordons; determinate bush varieties keep their branching growth.
  2. Install a support sized for the mature plant. A bush may benefit from a cage, while a tall cordon needs a firm stake or trellis.
  3. On a cordon, identify the main stem and a leaf stalk. A side shoot grows in the angle between them; a flower truss is different.
  4. Remove small unwanted cordon side shoots gently and tie the main stem loosely as it grows. Do not routinely remove bush tomato side shoots.
  5. Recheck ties and fruit weight. Retain useful leaf cover and avoid stripping the plant in hot weather.

What success looks like

  • The intended main stems remain supported without losing flower trusses.

Watch out for

  • Pruning a bush tomato as a cordon.
  • Mistaking a fruiting truss for a side shoot.
