How do you tell when it is time to re-pot a plant?

How do you tell when it is time to re-pot/re-soil?

Are there anything that we can do to help plants survive the winter?

Hi @moksie7,

One of the most obvious signs is when roots start growing out of the drainage holes at the bottom of the pot, indicating the plant has outgrown its current space. If you gently remove the plant and notice the roots are tightly coiled around the soil in a circular pattern, it’s likely root-bound and needs a larger pot. Other signs include slow growth, yellowing leaves, or water draining too quickly, which can mean the soil is depleted or the roots are taking up too much space. Additionally, if the soil looks compacted, dry, or has a white crust from mineral buildup, it’s time to refresh it. Finally, if the plant appears top-heavy or unstable, it may need a larger container for better support. Regularly checking for these signs will help ensure your plant continues to thrive.

To help plants survive the winter, there are several steps you can take. First, reduce watering since plants generally grow more slowly in colder months and require less moisture. Ensure they are placed in areas with adequate light, as daylight hours are shorter. Keep them away from cold drafts, heaters, or radiators, as extreme temperature fluctuations can stress plants. For outdoor plants, consider adding mulch to insulate the roots or covering them with frost cloths during freezing nights. Indoor plants may benefit from increased humidity, which can be achieved with a humidifier or by placing a tray of water near them. Lastly, avoid fertilising during winter, as most plants are in a dormant state and won’t benefit from extra nutrients until spring. 

If you can provide more information on the types of plants you're concerned about and your location that will help our members provide more tailored advice.

Please let me know if you have any questions.

Hi @moksie7,

Just thought I'd add to Mitch's reply that experienced member @Noelle has shared a comprehensive step-by-step guide How to pot a plant that you should find useful.

Thank you Mitchell - I have a young avocado plant in a pot and it hasn't grown (stayed at the same height) for a while.   The leaves have not turned colors and maintained green.   I don't see any roots shooting out at the bottom of the pot.  Should I re-pot?

If you can show us a picture of the plant, including the pot, that would be helpful in determining if it is due for a re-pot @moksie7. A plant not growing can't be entirely attributed to being in an undersized pot. 

Have you fertilised the plant recently? If not, that could be a reason for it not growing.
