Geez, Aslan, I just noticed your post. Sorry for the delay!
Yep, when you say "concern" ourselves, yea, we do. Whitetail deer nutrition is all our company does. We started the deer nutrition industry, and as far as I know, we are still the only company that derives its income solely from that endeavor. With regard to the SouthWest, the biggest problem we have had has, of course, been rainfall. Most of our planting mixes need the 30+ inches per year that most of the eastern US gets. We do have two low-rainfalll mixes though. Now, we have a perennial mix named Imperial Whitetail Extreme that will tolerate as low as 16 inches per year in rainfall, and lemme tell ya, it's dynamite there's a little evergreen forb / herb in there that honest to gosh tastes like watermellon; it's that sweet, and the deer flat nail it. We also have an annual alternative named No Plow that will pretty much grow anywhere winter wheat and oats can be grown.
Hope all's well with you. Good to hear from you again.
Best,
Jon
