Greenhouse job checklist - week 28

2 - 8 July 2012

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
