How to plant your seeds

Follow these simple steps to give your seeds the best start.

  1. Prepare your soil & tray

    Fill trays or small pots with seed-starting mix. Press gently to settle—no need to pack tight.

  2. Sow seeds at the right depth

    Plant roughly 2–3× the seed’s width deep. Tiny seeds can be pressed lightly into the surface.

  3. Water & keep warm

    Mist or bottom-water. Cover until sprouting if the packet suggests it. Keep in a bright, warm spot.
