Yes, growing mint in a self watering planter is not only possible—it’s actually one of the easiest and most successful ways to grow this herb indoors. Mint is a fast-growing plant that prefers consistently moist soil, making it a perfect match for reservoir-based watering systems.
Because mint tends to dry out quickly in traditional pots, many indoor gardeners struggle to keep it hydrated. A self watering planter helps solve this by providing a steady supply of moisture without the need for frequent watering.
Why Mint Thrives in Self Watering Planters
Mint naturally grows in environments where soil stays slightly damp, so it adapts very well to consistent watering systems.
Loves consistent moisture
Mint doesn’t like drying out. A reservoir keeps the soil evenly moist, which supports healthy leaf growth.
Fast-growing roots
Mint spreads quickly, and access to steady water encourages strong root development.
Low maintenance
Once set up properly, you won’t need to water your mint plant as often.

How to Set Up Mint in a Self Watering Planter
Getting started is simple, but a few details can make a big difference.
Choose the right planter size
Mint grows quickly, so a medium-sized planter (around 6–8 inches wide) works well for most indoor setups.
Use a well-balanced soil mix
Combine potting soil with perlite or coco coir to maintain both moisture and airflow.
Water from the top initially
When first planting mint, water the soil thoroughly from above to activate the wicking system.
Once the system is working, the plant will begin drawing water from the reservoir on its own.
Tips for Healthy Indoor Mint Growth
To keep your mint thriving, pay attention to a few key factors.
Provide enough light
Mint grows best with about 4–6 hours of bright, indirect sunlight.
Trim regularly
Frequent harvesting encourages bushier growth and prevents the plant from becoming leggy.
Avoid overfilling the reservoir
Although mint likes moisture, constantly saturated soil can still cause problems.
Common Issues to Watch For
Even though mint is easy to grow, a few issues can arise.
- Yellowing leaves from overly wet soil
- Slow growth due to low light
- Root crowding in small containers
Repotting when needed and maintaining a proper watering balance can prevent most problems.
