Uneven Recovery After Black Spot: Why One Mini Rose Lags

Uneven Recovery After Black Spot: Why One Mini Rose Lags

Strong fungicides can stress sensitive varieties. Your red mini rose likely reacted badly to the treatment, slowing its regrowth.

Recovery Aid

• Foliar feed: 1 tbsp fish fertilizer per quart water, sprayed on leaves every 2 weeks.
• This delivers nutrients directly to foliage, bypassing stressed roots.
• Apply to both roses for balanced vigor.

Long-Term Consideration

If the red variety remains disease-prone and weak, it may be inherently susceptible. Consider replacing with a more resistant miniature like 'Rainbow's End' or 'Sun Sprinkles'.
