Mildew Damage on Potted Roses in South Florida

Leaves

Diagnosing Shriveled, Stunted Growth

Three 20-gallon potted roses in South Florida show shriveled leaves, stunted growth, and blooms 1/3 normal size.

Photo shows classic mildew damage—fungus burns leaves, causing stunting and distortion. The damage is done on affected foliage.

No treatment needed for current damage. New, normal leaves will emerge within 2-3 weeks, and the roses will return to healthy growth naturally.
