Went with a $14 moisture meter over the finger test on my balcony tomatoes, and the numbers surprised me
I kept killing my cherry tomatoes on my third floor balcony here in Fresno, and I finally figured out it was watering, not sun. So last spring I had to pick between sticking my finger in the dirt like my mom does or dropping $14 on a cheap moisture meter from the garden center. I went with the meter, mostly because my pots are deep and my finger was never telling me the truth. Turns out the top inch was bone dry while the bottom of the pot was still soaked, and I'd been drowning them after 3 hot afternoons in a row. My plants perked up in about 10 days once I started waiting for the meter to hit 3 or lower before watering again. Now I'm wondering if the cheap meters drift over time, or if I should just trust it for a full season. Has anyone tested theirs against a scale to see if it's still accurate?
