Preparing Seed Trays

Preparing trays of seedlings can be an indoor or outdoor activity. Watching seedlings grow from a tiny seed into a mature plant reminds us that life continues, however dark it may seem at times. Seeds are a symbol of renewal and new chances.


Reduces stress and reaffirms continuity of life.

Materials required:

  • seeds
  • seed tray
  • firming board
  • sowing compost
  • watering can
  • permanent marker or pen
  • planting labels.


  1. Select seeds suitable for clients and the current season. Annuals are a good choice as they grow so quickly, as are salad vegetables.
  2. Fill the tray with compost, breaking it up as you do so. Fill the tray to about 1 cm from the top.
  3. Use your hand or a firming board to level the compost and compact it slightly. The firming board is a thin board that will fit inside your board. Drag the board across the top of the tray to make sure surface is flat and even.
  4. Moisten the soil. Use a watering can with a rose, so that the water is dispersed evenly and does not become too wet.
  5. Sow your seeds. Large seeds can be positioned individually, whilst smaller seeds should be sprinkled. Tiny seeds can be mixed with silver sand to make it easier to distribute them evenly over the seed tray.
  6. Some seeds then need to be covered in compost whilst others should be left uncovered. Check your seed packet to be sure. If the seeds need to be covered, sprinkle a light layer of compost over the tray.
  7. Compact the soil. Use your hands or the firming board to gently, but firmly press the soil down over the seeds.
  8. Label the tray. Use a permanent marker or pen to write the variety planted on one side of the label and the date planted on the other side.
  9. Follow growing instructions provided on the packet. This should include information on the temperature, amount of sunlight, and amount of water the seeds need.
