Greenhouse job checklist - week 19

6 - 12 May 2013

It's time to...

Fit automatic openers to greenhouse vents to encourage good air circulation
Plant tomatoes in growing bags or large pots, training them on to canes or wires for support
Bring pots of strawberries into the greenhouse to produce early flowers and fruit
Sow cyclamen and schizanthus for indoor flowers
Buy scented-leaf pelargoniums, such as 'Chocolate Peppermint' and 'Lady Plymouth'
Plant pots with heat-treated freesia corms to produce fragrant flowers this summer
Watch out for pests, checking under leaves and on shoot tips for signs of whitefly or red spider mite. Treat immediately, or introduce biological pest controls
