The effects of season, root pruning, and transpiration reduction techniques (anti-transpirant spray with and without foliar pruning and foliar pruning alone) on percent survival and rank of creosotebush (Larrea tridentata) transplanted from a native stand were estimated. Only season had a significant impact on survival determined 6 months after transplanting. Survival was higher in spring, summer, and fall than in winter. With regard to shrub rank 6 months after transplanting, there was no significant advantage over the most economical treatment combination of not root pruned-foliar pruned. Within this combination the spring and fall transplants were superior to winter transplants with summer transplants intermediate.
