Greenhouse job checklist - week 20

13 - 19 May 2013

It's time to...

Put up shading to reflect scorching sunlight and keep temperatures down
Open all vents on warm days, but close again in the evening
Order plug plants and seedlings by post, and pot up as soon as they arrive
Take leaf cuttings from houseplants, including African violets, begonias and Cape primrose
Hang yellow sticky traps over plants to catch whitefly and flying pests
Sow seeds of herbs, such as parsley, chives, coriander, garlic, basil, dill, fennel, mint, thyme, sage and lovage
