Feed & Water
- Water deeply and evenly — irregular watering causes splitting and blossom-end rot. Feed weekly with high-potash tomato food once first truss sets.
- If in doubt: water in the morning, feed once a week during flowering, and remove any yellow leaves at the base.
Greenhouse
- Damp down floors on hot days to raise humidity and deter red spider mite; ventilate mornings.
Outdoor
- Pinch out side-shoots on cordon plants weekly. Support heavy trusses; tie in the leader.
Pests
- Watch for whitefly, aphids and early signs of late blight (brown patches with pale halos on leaves).
Harvest
- Pick fruit when fully coloured and slightly soft. Leave the calyx on — it keeps them fresh.
