Step by Step Instructions

1 Select your seedlings
2 Prepare your pot for planting
3 Position your seedlings in the pot
4 Plant your seedlings in position
5 Apply seaweed concentrate to your seedlings
6 Apply fertiliser after three months
  • Step 1. Select your seedlings

    Knowing what to look for when choosing seedlings can help give your garden a great head start. Generally speaking, you need to make sure they look healthy with no dead ends. Make sure your pre-water your seedlings before transplanting to give them sufficient moisture.
  • Step 2. Prepare your pot for planting

    Planting your seedlings in a pot is a great option, particularly if you have a limited garden bed space. Make sure your pot is the right size for the amount of seedlings you have. If the pot is too small, the plants will be forced to compete for water and nutrients, and will most likely suffer. 

  • Step 3. Position your seedlings in the pot

    Fill the pot with a quality potting mix, until it is about three quarters full. Now position your plants an equal distance apart in the pot. This will balance out the plants and give them the best chance for growth. 

  • Step 4. Plant your seedlings in position

    Dig some holes for each of the seedlings. The trick is to make each hole double the size of the seedling, and the same depth as the seedling’s soil. To remove seedlings from their original pots, put your fingers around the plant, flip it upside down, and tap the bottom until the seedling slides out. Now place the seedling into the potting mix, using your hands to bring the soil to the sides of the plant. Try not to compress this too much. It’s a great idea to keep the tag next your plant.

  • Step 5. Apply seaweed concentrate to your seedlings

    Applying seaweed concentrate will give your seedlings the best chance for growth.

    Use a ratio of 30ml concentrate to 9L water and mix this into your watering can. Water the entire amount evenly over your plants using the watering can. Do not worry if your plants flatten out in the process, these will spring back within 24 hours.

  • Step 6. Apply fertiliser after three months

    Give your seedlings about three months to grow before using a granulated fertiliser.  Fertiliser helps to promote better root growth and foliage for your seedlings. Always refer to the instructions on your fertiliser on how to apply.
