A handy tool that measures the amount of moisture in your soil, letting you know just how wet or dry your soil is. Just remember not to leave it sitting in your soil or the tip will rust! To use: stick the moisture meter in the soil in several different locations near the root ball. If your soil is reading in the dry zone it's time to water! If it's reading anywhere above the dry zone let your plant dry out for a few more days before watering.
