Reviving a Drought-Stressed Rose in Phoenix Heat

Situation

A school garden rose bush in Phoenix, Arizona, received no water over summer while temperatures exceeded 100°F daily. Despite deep watering several times a week, the plant appears dry with dead branches and leaves.

Diagnosis and Action Plan

Roses in extreme heat suffer root stress, causing a wretched appearance. If canes are drying, the plant needs more water. Create a watering basin (a dish-shaped depression) around the base, apply mulch to retain moisture and cool roots, and prune back to green growth. Watering foliage is acceptable—it allows immediate water uptake, akin to rain. The rose will recover once the heat subsides.
