Architecture: every productive leaf needs light

Not every leaf sits in full sun. Inner, overlapping, or north-facing walls in a dense planting work less. Training, spacing, and a measured prune move light into the factory.

The intro series covers pinch-for-branch as a form tool. Here the job is light: a bush that shades itself is not automatically more yield.

If inner fruit is pale and outer fruit is fine, the architecture — not the bag — is the first fix.

In this series

• Ask what cuts sugar production — not which bag to add
• A crop is only as good as its root system
• Maximise yield per drop, not drops per hectare
• Yield falls before the leaf wilts
• Fruit drop is the plant aborting when resources fail
