After Mildew Treatment, Rose Stops Producing Buds: Recovery Timeline

A fall-transplanted rose bloomed in spring but had white coating on buds (mildew) and dry leaves. After spraying for mildew and insects, no new buds appeared. Leaves looked okay.

Mildew Aborted Buds

Powdery mildew destroys developing buds. The rose needs about a month to form new ones. If the spray didn't fully control the mildew, it may continue to suppress budding.

Wait and Watch

Allow a month for new buds. If none appear, the fungicide may be ineffective—try a different one. Some roses are repeat bloomers; others bloom once. This one sounds like a repeater.
