Not always—but in most cases, self watering planters do use special pots or inserts to function properly. These components are designed to separate the soil from the water reservoir and control how moisture moves upward to the roots.
While you can create similar systems with regular pots, purpose-built designs tend to be more reliable and easier to maintain.
What Makes a Self Watering Planter Different?
Unlike standard pots, self watering planters include a few key features:
- A water reservoir at the bottom
- A wicking system (fabric wick or soil column)
- A barrier or insert separating soil from standing water
These elements work together to deliver water gradually instead of flooding the soil.
In many store-bought designs, the “insert” is a removable inner pot that sits above the reservoir.
What Are Self Watering Planter Inserts?
Self watering planter inserts are internal components that hold the soil while allowing water to move upward from below.
They typically include:
- A perforated base or mesh
- Built-in wicking feet or channels
- Space for roots to grow safely above the water line
These inserts are what make the system consistent and prevent roots from sitting directly in water.
Can You Use a Regular Pot Instead?
Yes, but it requires some modification.
You can convert a regular pot into a self watering system by adding:
- A water container or tray below
- A wick (such as cotton rope or fabric strip)
- A way to separate soil from standing water

DIY setups can work well, but they often require more monitoring and adjustment than ready-made planters.
Store-Bought vs DIY Inserts
Both options have their advantages, depending on your needs.
Store-bought planters or inserts
- Designed for consistent water flow
- Easy to use and maintain
- Often more durable
DIY systems
- More affordable
- Customizable for different plants
- Require more setup and testing

When Special Inserts Are Most Helpful
Using a proper insert or dedicated planter is especially useful when:
- Growing moisture-sensitive plants
- Setting up larger indoor plants
- You want low-maintenance plant care
- You’re new to self watering systems
These designs reduce the chances of overwatering or poor wicking performance.
Final Thoughts
So, do self watering planters need special pots or inserts? Not strictly—but they definitely help. Purpose-built inserts improve consistency, reduce guesswork, and make the system more reliable.
While DIY solutions can work, using a planter designed for self watering is often the easiest way to get healthy, well-hydrated plants with minimal effort.
FAQ
Can you use any pot as a self watering planter?
Not directly. It needs modifications like a wick and reservoir to function properly.
Are inserts better than built-in systems?
Both work well, but built-in systems are usually simpler, while inserts offer flexibility.
Do self watering inserts fit all pots?
No. Inserts are typically designed for specific sizes and may not fit every container.
