What is Good Filler for Plant Pots?

If you enjoy gardening, you know that choosing the right soil for your plants is essential for their growth and health. However, sometimes the soil may not be enough to fill the entire pot, or you might want to save on soil. In these cases, using a good filler can be a convenient and cost-effective option. In this article, we will discuss some great fillers for plant pots.

1. Pea Gravel

Pea gravel is an excellent filler for plant pots. It is affordable, easy to find, and provides good drainage. The small, smooth stones allow water to flow freely through the soil, preventing waterlogging and root rot. The gravel also creates air pockets that allow the soil to breathe, promoting healthy plant growth.

When using pea gravel, make sure to cover the drainage holes at the bottom of the pot with a layer of landscape fabric or a coffee filter. This will prevent the gravel from falling out and blocking the drainage holes.

2. Styrofoam Packing Peanuts

Styrofoam packing peanuts are another good filler for plant pots. They are lightweight and easy to find, and they don't decompose over time. This means you can reuse them again and again. They also provide good drainage and improve the circulation of air in the soil.

When using styrofoam packing peanuts, make sure to cover them with landscape fabric or a coffee filter to prevent them from rising to the surface and becoming exposed.

3. Coco Coir

Coco coir is an eco-friendly filler for plant pots. It is made from coconut husks and is a renewable resource. Coco coir provides excellent drainage, retains moisture well, and is naturally resistant to fungus and bacteria. It also improves the structure of the soil and provides aeration.

Coco coir can be used alone or mixed with soil. It is available in bricks or loose form and is easy to find at garden centers and online.

4. Perlite

Perlite is a lightweight, porous material that is made from volcanic glass. It provides excellent drainage, improves aeration, and helps to retain moisture in the soil. Perlite is also sterile, so it won't introduce any pathogens or diseases to your plants.

Perlite can be used alone or mixed with soil. It is available in different grades, so make sure to choose the right one for your plants.

5. Vermiculite

Vermiculite is another good filler for plant pots. It is a natural mineral that is heated to expand and become lightweight and porous. Vermiculite improves aeration, retains moisture, and helps to moderate soil temperature. It is also sterile, so it won't introduce any pathogens or diseases to your plants.

Vermiculite can be used alone or mixed with soil. It is available in different grades, so make sure to choose the right one for your plants.

Conclusion

Using a good filler for plant pots can help to save on soil, improve drainage and aeration, and promote healthy plant growth. Pea gravel, styrofoam packing peanuts, coco coir, perlite, and vermiculite are all excellent fillers that are easy to find and use.
