      Cannot over water plants now

      Love my Sustee Moisture Meters. I have them inserted in my indoor and some outdoor pots. I cannot over water now like I did before and a few plants died. It makes so easy to check the colour every couple of days to see if I need to water . Just moved from Victoria to S. E. Queensland the daily temp and humidity makes such a difference now compared to living in Victoria.
