Water deeply at the root zone, wetting soil 18–24 inches deep for established shrubs. Rewater when the upper 2–3 inches begin to dry; increase frequency during extreme summer heat and reduce in winter. Containers and new plants need more frequent checks.
Roses (Rosa species and hybrids) are flowering shrubs or climbers valued for colorful, often fragrant blooms. Heat-tolerant cultivars perform best in Phoenix gardens.
Light: At least 6 hours of direct sun, preferably morning sun with afternoon shade. Avoid reflected heat from west-facing walls and pavement.
Water: Water deeply at the root zone, wetting soil 18–24 inches deep for established shrubs. Rewater when the upper 2–3 inches begin to dry; increase frequency during extreme summer heat and reduce in winter. Containers and new plants need more frequent checks.
Soil: Well-drained soil enriched with compost; slightly acidic soil is preferred. Phoenix’s alkaline soils may require nutrient management. Apply 2–3 inches of organic mulch, keeping it away from the crown.
Mature size: Varies by cultivar; many shrub and hybrid tea roses reach 3–6 feet tall and 2–5 feet wide. Miniatures are smaller, while climbers may produce canes 10–20 feet long.
Bloom: Repeat-blooming varieties flower most heavily in spring and fall, with fewer, smaller blooms during extreme summer heat. Once-blooming varieties generally flower in spring.
Evergreen / deciduous: Generally deciduous, but often semi-evergreen in Phoenix’s mild winters.
Growth rate: Moderate to fast during spring and fall; growth slows in extreme heat.
