How to grow your own seedlings in a few simple steps

There is nothing more gratifying than growing your own seedlings and enjoying the fruits (or vegetables) of your labor. Here are the steps to master seedling every time, from planting to transplanting. Grab a trowel and get started!
Difficulty level : Easy
Duration : 2 months
It is possible to sow your seedling in just about any sterilized container, so long as the water can evacuate. Many containers are made explicitly for seedling, such as peat pellet refills, recommended for small seeds. Biodegradable plantable pots, are perfect for larger crops, like pumpkins, or plants with fragile roots, like cucumbers, because they can be planted into the earth with the seedling.

Seedling planning

What types and quantities of containers, soils, and seeds will you need? How much space and sunlight do you have? What are your fruit and vegetable needs? When should you sow different seeds? Before digging into the project, put pen to paper and answer these questions.

Filling containers

  • 2.1 - Fill containers with soil.
  • 2.2 - Slightly tap the soil so the seeds adhere well.
  • 2.3 - If you want to use old soil, put it in the oven at 100°C for 30 minutes to sterilize it.

Pro tip

Add a third of vermiculite to the soil for optimal results.

Planting the seeds

  • 3.1 - Plant the seeds 4 times deeper than the diameter of the seed. For very small seeds, like carrots, simply cover them with a thin layer of soil.
  • 3.2 - Follow the recommendations on the packaging or our sowing calendar to plant seeds at the right time and with correct spacing.
  • 3.3 - Identify the seeds with little wood sticks.

Pro tip

If you have leftover seeds, save them in the refrigerator or freezer. If you opt for freezing, make sure to thaw the seeds for 24 hours before planting them.

Boosting germination

  • 4.1 - Water the seedlings without soaking them – a sprayer is perfect for the task.
  • 4.2 - Make sure the water drains appropriately.
  • 4.3 - Expose the seedlings to direct sunlight.

Pro tip

Cover seedlings with newspaper to maintain the humidity.

Pricking the plants

  • 5.1 - Water the plants and wait one hour.
  • 5.2 - Fill the individual containers with soil and vermiculite.
  • 5.3 - Delicately separate the plants, making sure not to damage the roots.
  • 5.4 - Make a hole in the soil of the containers and plant the roots of the young plants to the collar.
  • 5.5 - Lightly tap the soil around the plant and water it.
  • 5.6 - Place the plant indoors, in the shade, in order for it to regain strength.

Pro tip

For tomatoes, plant not only the roots, but a part of the stem in the soil. This allows the plant to become stronger, faster.

Transplanting to the garden

Before planting seedlings in the garden, they must harden off. The transition occurs over 15 days.
  • 6.1 - Start by placing the plants outdoors in the shade for one or two hours during the day.
  • 6.2 - Repeat for a few days, leaving them outside longer each day.
  • 6.3 - Then, leave them outdoors all day, in moderate sunlight, when there is no risk of them freezing.
  • 6.4 - Finally, plant them in the garden all the while respecting the correct spacing between the bulbs and rows.
