Hello, new plant pops here. I was recommended to purchase a moisture meter. I already have one, but I am not entirely sure how to use it. My meter has a scale from 1 to 10, where 1-3 indicates âDry,â 4-7 indicates âMoist,â and 8-10 indicates âWet.â Are âDryâ and âWetâ always undesirable, or does the optimal level vary depending on the type of plant I am caring for? For instance, I believe rosemary prefers to dry out slightly between waterings. Should I water it until the meter reads âMoist,â then check periodically until it reaches âDry,â and then water again? Conversely, for a tomato plant, which I believe requires more consistent moisture, should the soil always read âMoistâ when I check it?
