Any other tips for planting bulbs?
For best flowering results, store bulbs in a cool, frost free, place until you are ready to plant them. Remove bulbs from their packaging so they can get some fresh air, but make sure your pets don’t nibble them. It is important to plant bulbs within the same season that they are supplied.
