I start in prepared soil about the first of March...I use my backyard tree (Texas fan ash) as a guide which begins to fully bloom about the same time..
I always have a great advice or suggestions by one of the managers, his name is Daniel.
It depends on what kind of flower are you talking about. Some flowers do really well in the cold and some do much better in the heat. All the managers there are Really helpful. Let them know we're going to plant them and they can give you some advice..also try listening to Norm Schilling radio show called Desert Bloom on Thursdays he helps by giving advice on gardening on Vegas
