How to plant your seeds
Follow these simple steps to give your seeds the best start.
-
Prepare your soil & tray
Fill trays or small pots with seed-starting mix. Press gently to settle—no need to pack tight.
-
Sow seeds at the right depth
Plant roughly 2–3× the seed’s width deep. Tiny seeds can be pressed lightly into the surface.
-
Water & keep warm
Mist or bottom-water. Cover until sprouting if the packet suggests it. Keep in a bright, warm spot.
