Learn how to clean, maintain, and get the most out of your self-watering planter with simple, step-by-step care instructions.
Quick answer
Caring for a self-watering planter is straightforward: regularly clean the glass, check the cork bung, and refill the water compartment to keep your plant healthy and the planter looking clear.
Why regular care matters for self-watering planters
A self-watering planter works by drawing water from a lower reservoir up to the soil through a cord. Over time, mineral deposits, algae, or soil residue can cloud the glass or clog the wicking system. Regular maintenance keeps the water flowing freely and the glass crystal clear.
Because these planters are mouthblown from recycled glass, gentle handling and cleaning methods help preserve their unique character and prevent damage.
Step-by-step self-watering planter care
- 1. Empty and disassemble the planter: Remove the plant and soil from the top compartment. Take out the cork bung and separate the two glass sections. Pour out any remaining water from the lower reservoir. Do not pull the wicking cord out of the top compartment—it is threaded through the cork and should stay in place.
- 2. Clean the glass components: Wash each glass section by hand with warm water and a mild dish soap. Use a soft sponge or cloth to avoid scratching the recycled glass. For stubborn mineral deposits, soak the glass in a 1:1 white vinegar and water solution for 15 minutes, then rinse thoroughly. Never use abrasive scrubbers or harsh chemicals—they can etch the glass or damage the cork bung.
- 3. Rinse and dry the cork bung: Rinse the cork bung under cool running water to remove any soil or residue. Pat it dry with a clean towel and let it air-dry completely before reassembling. Cork can swell if soaked too long; avoid submerging it in water for extended periods.
- 4. Reassemble and refill: Insert the cork bung back into the lower compartment, then place the top compartment on top. Fill the lower reservoir with fresh water, add soil and your plant to the top compartment, and allow the wicking cord to draw water upward. Check the water level weekly—the reservoir should never be completely dry for more than a day.
