Transplanting a seedling at Rooted Flowers.From space issues to health, there’s many reasons why flower gardeners transplant their seedlings. Let’s take a look:

  • To give the seedlings more space to grow and develop strong root systems.
  • To provide better access to nutrients and water, which can help the seedlings grow faster and stronger.
  • To reduce competition among seedlings for resources.
  • To prevent the seedlings from becoming root-bound, which can limit their growth and health.

Generally, it's time to transplant seedlings when they have outgrown their initial container or tray, and have developed their first true leaves.

Once the seedlings have developed their true leaves, they are typically ready to be transplanted.

Additionally, if the weather is mild and the plants are hardy enough, they can be transplanted when they are a few inches tall and have at least two sets of true leaves.

Similarly, waiting too long to transplant can result in the seedlings becoming root-bound, which can limit their growth and health. A good rule of thumb is to transplant seedlings when they have outgrown their initial container or tray and have developed their first set of true leaves.

    1. Preparation: Choose a larger container or cell tray and fill loosely with soil. Level soil level as if you’d level a cup of flour in baking.
    2. Watering: Water the seedlings in their initial container or tray before transplanting. This helps to reduce stress on the plants during the transplanting process.
    3. Removal: Carefully remove the seedlings from their initial container, making sure not to damage the roots or stem. Gently hold the most robust part of the seedling, usually the stem.
    4. Placement: Make a hole with your finger and place the rootball of the seedling into the new soil. I like to use a pencil or flat head of a nail to push the root ball in. *Do not push on the stem, it could break. Firm the soil around the plant to ensure good contact between the roots and soil.
    5. Watering: Water the seedlings thoroughly after transplanting to help settle the soil around the roots and reduce stress on the plant.
    6. Care: Continue to care for the newly transplanted seedlings. They may look floppy initially but will perk up overnight.

    Transplanting is a technique and skill that every flower gardener should have in their seed starting bag of tricks.

    While the lisianthus might be delicate to look at, it's surprisingly hardy. These flowers can handle cooler temperatures better than many other blooms, and once they're cut and arranged in a vase, they last a long time. This durability and their capability to give two flushes of flowers make them a favorite for many, including myself.
