The 'new rose at my cottage' appears to have health problems!


May treat it for Black spot.

Rounded black spots with fringed edges appearing from July onward are the most obvious symptom of this disease. The big black spots appear
first on the lower, older leaves and then spread upwards. As the leaves grow they may turn yellow and eventually fall off.
Spray with a systemic fungicide, such as Benomyl, Triforine, Burpirimate or Carbendazim.
Burn affected leaves.

Powdery Mildew (Odium)
White powdery-looking coating on leaves, buds and flower stems, spreading quickly. (see further under "Flower buds do not open".

Suggestions appreciated! Found the above here: http://www.lillysrosegarden.com/rose-diseases-pests.html
