Give delicate plants extra shade

Put plants under your greenhouse benches for more shade when the sun is at its hottest. Some plants suffer in the heat, even when the vents are open – and those with delicate leaves or lush growth, like leafy herbs, will suffer the most.

Leave them in the shade for a few days if the forecast is for hot weather, but for them to grow well, you will eventually need to move your plants up for a bit more light.

Herbs such as parsley will dry out more slowly and are less likely to wilt if moved to a cool and shady spot on hot days
