Where Have All the Flowers Gone?

Rosie Lerner, Extension Consumer Horticulture Specialist, Purdue University.

While some spring flowering trees and shrubs performed admirably this season, some species had few or no blooms at all.  In addition, some plants were so late to leaf out that they had many of us concerned that they had died overwinter.  Some shrubs such as forsythia flowered only on the lower branches where snow cover provided good insulation.   While it is still possible that these plants may continue to show effects of the harsh winter, most of these plants should recover and return to normal blooming next year, assuming reasonable weather.  We recommend conservative pruning to remove only dead branches and conserve as much foliage as possible so the tree to maximize leaf area for photosynthesis for recovery.
