Moisten the planting mix so it's slightly damp. Place an inch or two of potting mix in the pot and place the bulb on top of it, roots side down, pointy end up. You want to end up with about 1/3 of the bulb exposed above the soil line, so add or remove potting mix underneath the bulb, if necessary. Place more mix around the bulb, firming it as you go, until it's within an inch of the pot rim.
