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.

End of Season

  • Stop the leader once four to six trusses have set under glass. Remove lower leaves to help ripening.

Feed & Water

  • If in doubt: water in the morning, feed once a week during flowering, and remove any yellow leaves at the base.
