These deciduous trees are widely adapted throughout the U.S. having varieties suitable to every state. Santa Rosa is one of the most popular varieties in Arizona. They produce sweet plums that are attractive to birds. Consider a fine mesh bird netting.
Newly planted trees need more frequent watering until they are well-rooted. If a new plant wilts or has dull leaves, it is a sign you aren’t watering enough. In Arizona, watering your plants too much during the spring can cause yellow leaves and root rot. You should take special care not to let your trees stand in pooling water. The best time to prune your fruit tree is during the dormant season, the first months of the year. Annual pruning controls the tree size and ensures better fruit quality.
