When is the last frost in the Southwest? I get this question almost on a daily basis at our University retail gardening store.
I could get the answer from the local TV, Radio or online weather information services. But as you know they can sometimes be unreliable.
However the best answer comes from nature itself. Mesquite trees and shrubs. Look closely at these great looking drought tolerant shrubs. If you see small buds and or foliage you can bet the cold frosty mornings are no longer a problem for this season.
