The Gardman Soil Moisture Meter will set you back $11.95 and provides a guide for optimal watering of plants and lawns either indoors or outdoors.
The reaction to the tool has been positive on social media. In the Facebook group, Crazy Indoor Plant People Australia, one user said the meter changed her life.
"I found worms whilst repotting a plant and totally freaked out. Now I'm petrified of sticking my finger in my plant's soil to check if I need to water. Got this handy tool from Bunnings today!! #lifesaver."
Another user in the group agreed, saying the meter is great but warned people to wash it after each use.
"These are great but be sure to sterilise with each use. Otherwise, you'll just be transferring diseases from pot to pot. I learnt the hard way," they said.
