Prune and Feed
Lightly prune, feed, and water roses on a weekly or bi-weekly basis to encourage them to flower continuously into the late fall. But use only one-quarter the amount of fertilizer that you'd use if you fed them less frequently. The object is to apply a minimal amount of fertilizer each time you water.
Keep the Blossoms Coming
Trim faded blooms down to the first five-part leaf throughout the season. New blooms will appear in about three weeks.
Give Roses an Overall Pruning
Prune branches all over the plant to maintain a pleasing shape. This helps strengthen the lower canes and root system.
Smash the Suckers
Remove suckers from below the graft. Then smash the bases of the sucker growth so repeat growth is discouraged.
Cut Bouquets at Day\'s End
Cut roses last longer when cut late in the day, unlike other blooms, which last longer when cut early in the morning. Those cut after 4:30 p.m. will last up to ten hours longer than those cut at approximately 8:00 a.m. The sugar that the leaves manufacture and store during the day remains in the leaves, nourishing the blooms. In flowers cut early in the morning, those sugars have traveled to the stem and roots during the night, so there\'s little left in the leaves to feed the blooms.
