Repotting a plant from a plastic container is a simple process, but it can be a stressful experience for the plant. It is recommended to repot a plant when you notice signs such as roots growing through the drainage holes, the plant drying out faster than usual, or leaves drooping or turning yellow. The first step is to gently remove the plant from its current pot by turning it sideways and tapping the bottom of the container until the plant slides out. Next, loosen the plant's roots with your hands and trim any extra-long thread-like roots, leaving the thicker roots intact. Remove about one-third of the old potting mix and add a layer of fresh potting soil to the new planter. If the new planter doesn't have drainage holes, use lava rocks or similar materials at the bottom for better drainage. Finally, place the plant in the centre of the new planter, add more potting mix around it, and water it well.

When to repot
Repotting a plant can be stressful for the plant, so it is recommended to avoid doing it too often. Plants typically need to be repotted every 12 to 18 months, depending on their growth rate. Slow-growing plants can stay in the same pot for years and may only need a soil replenishment.
Spring, before the start of the growth season, is usually the best time to repot your plants. It is recommended to avoid repotting in extreme temperatures, especially during heat waves, as it can add extra stress to the plant.
There are several signs that indicate it is time to repot your plant:
- Roots are growing through the drainage hole at the bottom of the planter.
- Roots are pushing the plant up, out of the planter.
- The plant is growing slower than normal (different from winter dormancy).
- The plant is extremely top-heavy and falls over easily.
- The plant dries out more quickly than usual, requiring more frequent waterings.
- The aboveground parts of the plant take up more than three times the pot space.
- There is a noticeable salt and mineral buildup on the plant or planter.
- The plant's leaves are drooping or starting to yellow, even though you are watering it properly.
If you have just purchased a new plant, it is recommended to wait a few days or weeks for it to acclimate to your home before repotting it.

Removing the plant from the plastic container
Removing the plant from its plastic container is a delicate process. Firstly, it is important to assess whether your plant is root-bound, meaning that the roots are growing in very tight circles around the base of the plant. If this is the case, you will need to carefully unbind the roots and trim them. If your plant is root-bound, it may be easier to cut it out of the pot, especially if it is a large plant or the roots are very tight.
Once the roots have been loosened, you can begin to remove the plant from the plastic container. Turn the plant sideways and gently hold it by the stems or leaves. Tap the bottom of the container until the plant slides out. You may need to give the base of the stems a light tug to help it out. If the plant is firmly attached, you can try squeezing the sides of the pot to loosen the soil or use a small shovel or butter knife to help ease it out.
As the plant comes out of the container, gently grasp the base of the plant to steady it as you slide off the pot. If the roots are very tight, you can start by gently massaging the roots at the bottom until they loosen from their coils, and then continue massaging the roots until they are all loose.
Once the plant is out of the container, you can shake off any loose soil so that you are left with just the plant and its roots. This will make it easier to place the plant in its new pot and add the new soil.

Preparing the new planter
Choose the Right Size
When selecting a new planter, it is important to consider the size of your plant and its roots. If your plant has outgrown its current plastic container, choose a new planter that is slightly larger, typically 1 to 2 inches larger in diameter for tabletop planters and up to 4 inches for floor planters. This will provide enough room for your plant to grow without adding too much extra soil, which can affect water absorption.
Drainage and Aeration
Ensure that your new planter has a drainage hole at the bottom. Proper drainage is essential to prevent waterlogging and promote healthy root growth. If your new planter lacks a drainage hole, create a layer at the bottom using materials such as lava rocks, gravel, pebbles, or a thin layer of plastic mesh. This layer will help with drainage and prevent soil from escaping through the drainage hole. Additionally, aerating the soil by creating small holes will enhance the absorption of air, water, and nutrients by the roots.
Prepare the Soil
Start by adding a layer of fresh potting soil or compost to your new planter. Pack it down gently, removing any air pockets. If reusing the old soil, mix it with fresh potting soil to replenish nutrients. When adding the plant to the new planter, ensure it is centred and secure. Do not pack too much soil around the plant, as this can affect root breathing.
Watering
After repotting, water your plant thoroughly and slowly. Newly transplanted plants experience stress, and ample watering helps them recover. Water until the pot feels heavy and water runs out of the drainage holes. You can let the pot sit in a saucer for a while to absorb any excess water, then dump the remaining water. Your plant might need less frequent watering in the first few weeks after repotting due to the increased soil volume.
Remember, preparing the new planter is just one aspect of repotting a plant. Other steps, such as removing the plant from its current plastic container and loosening the roots, are also important for a successful transition.

Adding the plant to the new planter
Once you have removed your plant from its plastic container, you can begin to add it to its new planter. If your plant is root-bound, you will need to carefully loosen the roots with your hands, unbinding them from their tight circles and giving them a trim. If your plant is not root-bound, you can simply place it on top of the fresh layer of mix in the new planter.
When placing your plant in its new planter, ensure that it is centred. You can then add potting mix around it until it is secure. Be careful not to pack too much soil into the planter, as the roots need to breathe. If your plant is not root-bound, you can also choose to place it in a plastic pot before putting it into the new planter. This works well if your new planter is a cache pot, which is a decorative pot without holes.
If your plant has been sitting in its plastic container for a long time, it may be pot-bound. This means its roots have run out of room to grow. In this case, you should repot your plant into a new planter that is only slightly larger—no more than 1 to 2 inches in diameter for tabletop planters and no more than 4 inches for floor planters. If you are repotting a very small plant, your new planter might only need to be an inch larger. If you are repotting a large plant, you can follow the same guidelines.
If your new planter does not have a drainage hole, you should layer the bottom with lava rocks, gravel, or similar materials before adding the potting mix. This will help with drainage. Once you have placed your plant in its new planter and added the necessary potting mix, you can water it well. A freshly repotted plant does not need to be fed fertilizer.

Aftercare
Repotting is a stressful time for a plant, so it is important to take good care of it afterward. Firstly, it is best to avoid repotting in autumn or winter when plant growth slows or completely stops, as this increases the risk of fresh compost sitting too wet. Spring is generally the best time to repot, as plants start into growth, but early to midsummer is also suitable for many plants.
After repotting, it is recommended to wait until the soil has mostly dried out before removing the plant from its ceramic or terracotta pot. If you have repotted a succulent, it is a good idea to remove extra soil or peat from the roots to give them the best chance to get established in new soil. Succulents have shallow root systems and grow more slowly than other plants. For vine, grass, or tree-type plants, you can mostly leave the roots alone. Just shake away excess soil or slightly loosen a root ball with your hands if the plant was root-bound.
If you have repotted your plant into a larger container, you will likely need to water it more. However, be careful not to overwater, as this can lead to root rot. To avoid this, ensure your planter has good drainage, and do not pack too much soil into the planter, as you want the roots to breathe. If your planter doesn’t have a drainage hole, layer the bottom with lava rocks, gravel, or a similar material before adding the potting mix. You can also use a thin layer of pebbles or rocks at the bottom of the pot, but this takes up space and adds weight to the planter.
If you have cut the plant out of its pot, keep a close eye on it for any signs of stress or damage to the roots. If your plant is root-bound, it is important to unbind the roots and give them a trim. You can prune off any thread-like roots that are extra long, but make sure to leave the thicker roots at the base of the foliage.

Frequently asked questions
If the roots are poking through the drainage holes, the plant is pot-bound and needs repotting. Other signs include drooping or yellowing leaves, slow growth, and the plant drying out more quickly than usual.
Most plants need repotting every 12 to 18 months, but slow-growing plants may only need repotting every few years. Spring, before the growth season, is the best time to repot. Avoid repotting in extreme temperatures.
Choose a pot that is only 1-2 inches larger in diameter than the current pot. This ensures there is room for growth without adding too much extra soil, which can lead to issues.
For plastic pots, you can gently squeeze the sides to loosen the soil. You can also use a small shovel or knife to help loosen the soil from the edges. Turn the plant on its side and tap the bottom of the pot until it slides out.
Water the plant well and place it in a saucer to soak up excess water. Newly transplanted plants need ample water to recover from the stress of repotting.
