Knockout Rose Yellow Leaves After Drought Then Rain: Weather Stress

Knockouts planted last year, some freeze damage, recovered. Then drought → heavy rain. Now yellow leaves. Asks: too little or too much water?

Weather Whiplash = Stress

Drought → flood = ideal stress conditions. Roots can't adapt fast enough → yellow leaves.

Roses will regreen when conditions stabilize. No treatment needed. Just time.
