under-watering and over-watering can be detrimental to plants.
The best way to determine whether a plant needs water is to
check the soil moisture. With the InGauge Soil Moisture-Tester
it is now easy to know when and how much to water
potted and garden plants, lawn & small trees. The InGauge
Soil Moisture-Tester is a heavy-duty, recycled plastic
gauge that tests soil dampness. Just insert the blade into
the soil and pull it out. To determine dampness, observe soil
color and how it clings in any of the five evenly spaced notches.
The handy moisture-tester can be left in soil
all-year as a beautiful garden accent and then used to test
soil whenever needed.
