Rainfall varies from area to area. Check that your vegies/garden have received sufficient water by simply keepng an eye on the rain guage. When you know how much rain you have had, you can conserve water becuase you don't need to water the garden if there has been enough rain. Using a rainguage takes the guesswork out of the watering decision!
This rainguage comes with an installation guide, and directions for recording rainfall.
