Seedlings should be repotted when their roots begin to outgrow the current container. This is usually indicated by visible roots poking out of the drainage holes or becoming root-bound. Repotting helps provide enough space for the seedlings to continue growing and develop a strong root system.
One famous gardener, Peter Cundall, once said, “Repotting seedlings at the right time is crucial for their healthy development. Neglecting to repot them can stunt their growth and lead to root rot.”
Here are some interesting facts about repotting seedlings:
-
Timing: Seedlings should generally be repotted when they have developed their first true leaves, which usually occurs about two to four weeks after germination. This allows them to establish a healthy root system before transplanting them into larger containers or outdoor beds.
-
Container Selection: When choosing a new container for repotting, it is important to select one that is slightly larger than the current container to allow for root growth. Avoid using containers that are too large, as excessive soil volume can lead to moisture retention and root rot.
-
Soil Mix: Use a well-draining soil mix specifically formulated for seedlings or young plants. A good mix usually consists of equal parts compost or peat moss, perlite or vermiculite, and garden soil or potting mix. This helps provide adequate drainage while retaining enough moisture for the seedlings to thrive.
-
Transplanting Technique: Gently remove the seedling from its current container, being careful not to damage the fragile roots. Placing your hand over the soil surface, turn the container upside down and tap the bottom to release the seedling. Hold the seedling by its leaves, not the stem, to minimize any stress on the roots. Plant the seedling in the new container, making sure to bury it deep enough for the soil to cover the entire root system.
-
Watering and Care: After repotting, water the seedlings gently to avoid disturbing the newly planted roots. Keep the soil consistently moist, but not waterlogged, to promote healthy growth. Place the repotted seedlings in a well-lit area, preferably near a window or under grow lights, to provide sufficient light for photosynthesis.
Table: Benefits of Repotting Seedlings
| Benefits | Description |
|---|---|
| Prevents root-bound growth | Repotting helps prevent the seedlings’ roots from becoming root-bound, which can hinder their growth. |
| Allows for better nutrient uptake | By repotting, seedlings are provided with fresh, nutrient-rich soil that allows for better nutrient absorption, supporting healthy growth. |
| Promotes stronger root system | Repotting seedlings into larger containers encourages the development of a robust root system, which improves overall plant health and resilience. |
| Enables continued growth | As seedlings outgrow their initial containers, repotting provides them with ample space to continue growing and flourishing. |
| Prevents competition for resources | Repotting allows seedlings to have sufficient space and resources without competing for nutrients, water, and light, leading to healthier growth. |
| Helps transition to larger pots | Repotting is an essential step in the gradual transition of seedlings from small containers to larger pots or outdoor beds, ensuring their successful acclimatization. |

By following these guidelines and ensuring proper care, seedlings can flourish and reach their full potential. Remember, repotting at the right time and with the right technique is key to nurturing healthy and thriving plants.
Video answer to “when to repot seedlings?”
This video discusses the timing and methods of transplanting seedlings, focusing on different types of plants such as vegetative, fruiting crops, and house plants. For vegetative and fruiting crops, transplanting is recommended when the roots start to come out of the drainage holes. However, for house plants, it’s best to transplant when the roots make up around 50% of the available soil volume. The video also mentions the exception of tomatoes, which can be buried deeper due to their ability to set roots along the stem. Lastly, the importance of avoiding the mistake of burying plants too deep is emphasized.

After 6 to 8 weeks under the grow lights, many of the seedlings need to be repotted into larger containers to ensure continued healthy growth until it’s time to move them into the garden. You’ll know your seedlings are ready to be repotted when their roots have filled their current containers and their foliage is crowding out the neighbours.
But how do you know when to repot seedlings? 1. They have one or two sets of true leaves The ideal time for transplanting your seedlings is about 3 weeks after they… 2. The cotyledons are turning yellow and falling off Cotyledons are the first leaves that emerge from a seed. They are… 3. The
When To Repot Seedlings they have grown to be twice as tall as the height of the container they’re in there are a lot of roots growing out of the bottom of the seed cells (i.e.: they’re pot-bound) they’ve stopped growing larger, or their growth is stunted the soil dries out so quickly that you have
The best time to repot houseplants is in the spring between February and April. This is when the growing period begins, so once your houseplants are in new soil, they can immediately start producing new leaves.

Ideally before they’re transplanted, seedlings should be at least twice as tall as their starter trays. So, that would be about 3-4″ tall.
