Greenhouse job checklist

4 - 10 July 2016

It's time to...

  • Pinch out tomato sideshoots developing from the main stem
  • Fit automatic vent openers to help control air flow and fit extra low-level louvre vents if required
  • Tie in tomato shoots to their supports. Water daily to prevent the compost drying out, which can cause split fruits and blossom end rot
  • Thin out bunches of grapes with pointed scissors
  • Pinch out shoot tips on coleus to encourage plants to branch, and remove any flowers that form
  • Propagate pelargoniums from cuttings during July and August to grow strongly rooted plants that will survive the winter
  • Feed crops in growing bags and pots every week
  • Watch out for vine weevil beetles and larvae, and treat compost with a suitable product such as Provado Vine Weevil Killer 2
