Hi Randy,

I grow hundreds of different tulips to recreate a historic garden display
in Salem, Oregon every year. We have a pretty elaborate process for dealing
with the tulips in the garden, after they are finished blooming, usually
around May, but before the leaves die back they are dug up, dipped in a
sulfur or copper solution to deal with fungal issues and bundled up by
variety, wrapped in burlap and then healed in a dry bed until the leaves
die back in mid summer....

This is done because the summer beds that display the tulips are irrigated
for the summer perennial and annual display and most tulips don't want any
summer water, but you have to let the leaves die back attached to the bulbs
so they set flowers for the next season. After the leaves have all died
back the bulbs are graded out with the largest and healthiest saved for
next years display, these are stored in paper bags, after a sulfur dusting,
and stored in a cool garage until the fall rains return.

In October or November the Tulips are planted back into the beds and the
whole process starts over, ....
