Soil pH test kit
Measures soil acidity/alkalinity to match plants to conditions and detect contamination. Explains why certain plants thrive in specific urban spots.
What to look for
- 1pH range 3-10 covers most urban situations from acidic wood mulch to alkaline concrete runoff
- 2Probe-style meters give instant readings; paper strips require water mixing but cost less per test
- 3Depth markings or 4-inch probe length for root-zone testing, not just surface
- 450+ tests minimum for strips, replaceable probe tips for electronic versions
Skip
- Meters that only test moisture—pH is the critical measurement for plant selection
- Decorative meters without calibration—accuracy matters for deciding what will actually grow
Used for: testing guerrilla garden sites before planting · understanding why forageable plants cluster in certain spots · assessing neglected urban soil quality · matching plants to median strips and parkways
