How to damp down your greenhouse

Do it:

Jun, Jul, Aug

Takes just:

15 minutes

Take 10 minutes first thing in the morning, during the height of summer, to pour water onto the floor of the greenhouse. This simple task creates enough moisture throughout the day to prevent your plants from suffering heat stress.

You will need

  • Watering can full of water


When the weather forecast predicts hot and dry weather, pour water on the greenhouse floor early in the morning. This allows the water to slowly evaporate during the day, adding much-needed moisture to the air.


Dampen the greenhouse floor, not the plants. Water dripping onto leaves encourages fungal disease, while water splashed onto fruit can ruin its appearance.
