What is the best season for planting native desert plant species?

• A. Summer
• B. Fall
• C. Mid Winter
• D. Late Spring

Answer: (B)

Planting native desert species in fall is best because it gives roots time to establish during cooler, moister conditions before the next hot, dry summer. The soil remains warm enough for root growth while air temperatures are milder, and autumn rains or reduced irrigation help keep moisture available without heavy evaporation. This window minimizes transplant shock since the plant can focus energy on root development rather than new top growth. In contrast, summer plantings face intense heat and water stress, while winter planting can slow establishment as many desert natives are less active and late-spring plantings can hit rising heat before roots are well established.
