Best Moisture Meters

Overwatering kills more container plants than drought, and a moisture meter takes the guessing out of it. You push the probe into the pot and read whether the soil is dry, moist, or wet at root level, which is far more reliable than poking a finger into the top inch, especially in deep planters where the surface lies about what is happening below. Most balcony gardeners are well served by a simple analog probe that needs no batteries. Look for a probe long enough to reach the root zone of your pots, and treat the reading as guidance you combine with knowing which plants like it dry and which like it damp.
