This program is not yet available but coming very soon from what I have heard.
The Society of American Florists has lobbied for funds to be available to floriculture growers also

It is certain that applying quickly will be essential as there is likely not enough money in the fund to cover the need. I’ll let you know when I hear any updates, but check back frequently on the USDA website so you will know when the applications are available.
Thanks to John Sanderson for letting me know.
