Visual Moisture Indicator: See exactly when your plant needs water with a simple color change—no apps, batteries, or guesswork. Know When to Water: White = dry. Color where the soil begins = still wet—wait before watering to avoid overwatering. Designed to Break Down: Works through multiple waterings, then naturally breaks down in soil—this is intentional, not a defect. Still Changing = Still Working: As long as color appears near the soil line, your PlantDoc is actively reading moisture. 5-Pack for Ongoing Use: Distribute across plants or replace over time as part of your watering routine. Stop guessing when to water your plants. PlantDoc is a biodegradable moisture indicator that shows when your soil is dry—using a simple color change. WHITE = dry → water your plant COLOR where the soil begins = still wet → wait Designed to work through multiple watering cycles, PlantDoc naturally breaks down in soil over time. This is part of the design. As long as it’s changing color, it’s still working. Over time, natural soil tannins may cause browning—this is normal and does not affect performance. When it begins to break down, simply add a fresh PlantDoc to your watering routine. No plastic. No batteries. No guesswork.
