The short answer
Choose for the plant’s requirements and mature size as well as your space. One recommended pot volume will not suit every crop.
See the sourceIn this guide
Check your situation
- Check crop-specific container requirements.
- Measure usable internal space and confirm drainage.
- On a balcony, consider access, stability and building load limits.
What to do now
- Choose the plant before settling on the container.
- Check internal dimensions rather than only the outside diameter.
- Estimate volume when comparing suitable containers.
What not to do
- Do not choose by appearance alone.
- Do not put a small plant into an enormous pot just because larger established plantings dry more slowly.
Do you need to buy anything?
Keep a pot with suitable dimensions and drainage. Consider filled weight before choosing another.
