The 'John F. Kennedy' white hybrid tea rose thrives in full sun with proper winter protection for its first year.
Roses need 6-8 hours of direct sun for optimal bloom, disease resistance, and cane ripening. Afternoon shade tolerance only applies after the minimum sun requirement is met. Plant your JFK rose in the sunniest location available—your pink rose's sunny spot is ideal.
Newly planted roses lack deep roots. Mound 12 inches of soil/compost/mulch around the base after full dormancy (leaves dropped, ground frozen). This insulates the vulnerable crown and young roots from Boston's freeze-thaw cycles.
Boston's humidity favors fungal diseases. Ensure good air circulation, water at soil level (not foliage), and consider preventive sulfur sprays in spring.
