Princess Diana Rose: Bloom Cycle and Pruning Guide for New Gardeners

A new rose gardener asked if their Princess Diana rose blooms only once a year and when to prune, as they expected more flowers.

Flush Blooming Habit

Princess Diana blooms in flushes: a heavy crop in early summer, a pause of a few weeks, then another bloom cycle. Newly planted roses often take a year to establish and produce their full flowering potential.

Pruning Timing

Do not prune a first-year rose. Wait until the following spring, then cut back by about one-third. This encourages vigorous new growth that will carry the next season's flowers.
