Water is a vital part of thriving plant life; without it, your plants would shrivel up and die. Ensuring your plants receive precisely the amount of water they need can be difficult, especially if you’re new to gardening. But even the most experienced gardeners over- and under-water their plants once in a while. When you’re taking care of a jungle of plants, it can be hard to remember the specific needs of each one.

While a quick poke in the dirt can tell you if the soil is soaking wet, it’s tougher to discern more subtle moisture levels. Checking moisture levels can also help you determine how well your soil is retaining water; if your soil feels dry after a rainstorm, it may be draining too well. With the help of a soil moisture meter, you can do away with some of the guesswork and get it right almost every time.

What do the best soil moisture meters have in common? A quality soil moisture meter will be accurate.  A soil moisture meter should also be durable, particularly if you’re planning to use it to measure moisture levels outdoors. And though it’s important to keep it out of the elements when not in use, it should be rust-resistant, as it will be exposed to a lot of dirt and moisture. A sturdy construction will also help prevent potential breakage when inserting the meter in heavy clay soils.

Some soil moisture meters also boast additional features like sensors for measuring pH, sunlight, and other factors. Multifunction soil moisture meters can provide a quick snapshot that may alert you to potential problems. If your soil pH reading is off the charts, for instance, you should complete a soil test.

A practical soil moisture meter will also have an easy-to-read display, whether that’s digital or analog is up to you. Either way, the characters on the display shouldn’t make you squint, both to ensure you’re reading the measurements correctly and to prevent eye fatigue.
