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.

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.

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.

Hi Mitch - One is a Lychee plant and the other an Avocado plant....both have not grown much recently.
I moved the succulent plant off the Avocado plant briefly and found these grub and earth worms....do they affect the soil and the roots of these plants?
Please see images below.
Thanks,
Ben
Hello @moksie7
Looking at your photo the plants don't appear to have outgrown their pots. However, the presence of grub and earthworms is bit concerning.
Grubs and earthworms have a complex relationship with potted plants. Grubs, the larvae of beetles, are generally considered bad news. Many species feed on plant roots, which can significantly weaken or even kill your potted plants. If you discover grubs in your pots, it's best to remove them manually and replace the infested soil. Pesticides like OCP 250ml Eco-Neem Concentrate Botanical Insecticide can also be an effective control method.
Earthworms, on the other hand, are beneficial in garden beds, where they aerate the soil and break down organic matter. However, their presence in pots can be more problematic. While they don't eat living plant tissue, their tunneling can disrupt drainage, creating pathways for water to escape too quickly and dry out the soil. Over time, their castings can also compact the soil, making it dense and poorly aerated.
Additionally, they may break down the components of the potting mix too quickly, reducing its suitability for plants. While a few earthworms in a healthy plant's pot might not be a major concern, if you're worried about their impact, you can try to remove them or repot the plant with fresh soil.
Please remember to wear personal protection such as gloves, goggles and a mask when using chemical sprays.
