New Rose Bush Produces Miniature Blooms – Heat and Water Stress

Peach Roses Now Small, Not Double

Planted spring, bloomed large. Two months later, blooms small. Bayer 3-in-1 applied, not due for reapplication.

Cause

Sudden high heat causes roses to reduce flower size to conserve water. Fertilizer in heat is not absorbed (roots shut down).

Action

Water deeply, stop fertilizing, let plant acclimate. Large blooms will return when weather moderates.
