All of our bulbs come needing to be planted with in a few weeks of shipment which is based on our region. It is recommended to plant the bulbs once the soil temperatures reach 55*F which happens to be in September or October here in our area. South of here that could be as late as November. You want it to be cool enough the bulbs remain dormant, but warm enough you can still dig to plant them. Remember to pay attention to the depth needed for the particular bulbs you are planting. The general rule of thumb is a depth 3x the height of the bulb. If too shallow they could incur damage and loose viability.
