Notes
So long as the water can evacuate, you can sow your seedlings in just about any sterilized container. Many containers are made explicitly for seedlings, 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, as they can be planted directly into the earth with the seedling.

1
Creating a Plan

  • 1.1Learn about the needs of the seedlings you wish to grow.
  • 1.2Make a schedule for sowing different types of seeds.
  • 1.3Consider the amount of available sunlight and space you have.
  • 1.4Decide how many and what types of containers you want to use.
  • 1.5Figure out how much soil you require.

2
Filling the containers

  • 2.1Fill all of your containers with soil.
  • 2.2Tap the soil down lightly and add more if needed.
  • 2.3If using old soil, sterilize it first by placing it in the oven for 30 minutes at 100°C.

Pro Tip

Mix your soil with one-third vermiculite for greater moisture and nutrient retention.

3
Planting the Seeds

  • 3.1As a rule of thumb, most seeds should be planted about four times deeper than their diameter.
  • 3.2Small seeds, like carrot seeds, should remain closer to the surface with only a thin layer of soil overtop.
  • 3.3Refer to the seed packet or our sowing calendar for recommendations on when to plant seeds and how to space them.
  • 3.4Use small wooden sticks to mark the location of different seeds.

Pro Tip

Leftover seeds can be stored in the freezer or refrigerator. If frozen, make sure to allow them to thaw at least 24 hours prior to planting.

Fostering Germination

  • 4.1Water the seeds but take care not to soak them. Using a sprayer is ideal.
  • 4.2Ensure that the water drains properly.
  • 4.3Place the containers under direct sunlight.

Pro Tip

Covering the seedlings with newspaper can help maintain humidity.

5
Pricking out the Seedlings

  • 5.1Wait one hour after watering before pricking out seedlings into individual containers.
  • 5.2Fill each container with your soil and vermiculite mixture. Make a hole in the soil.
  • 5.3Separate the seedlings with care to prevent damage to the roots.
  • 5.4Replant individual seedlings into their new container. Lightly tap down the soil around the roots.
  • 5.5Water the seedling and place it in the shade to regain its strength.

Pro Tip

When pricking out tomatoes, plant part of the stem into the soil as well to promote stronger growth.

6
Transplanting Into the Garden

  • 6.1Start exposing the seedlings to the outdoors to harden them off and prepare them for planting.
  • 6.2Over the first few days, place the seedlings in a shaded spot for one to two hours, increasing the amount of time each day.
  • 6.3Once there is no longer risk of freezing, begin leaving the seedlings outdoors all day in moderate sunlight.
  • 6.4After about 15 days, you can plant your seedlings in the garden. Be sure to space out the bulbs and rows correctly.
