YES! It will prosper only with fungicide sprayings on a regular basis.

Depends on the zone. She will BS here, but not defoliate. Even without regular spraying.

In humid areas, I hear she's a complete disaster, but will still continue to bloom.

This rose is a very, very, very prolific blooming machine.

Thanks for your feedback.
I reckon it's a good thing that the spots I have planned for JL are in the spray area of our garden.

She's one of those roses that is on a strict spray schedule once blackspot season starts. No powdery mildew at least. Oh yes, and watch for spider mites too. Her pluses outweight her negatives for most (myself included). Prolific spring blooms (with moderate repeat thereafter), amazingly vigorous, she's a real show stopper in spring.

I'm thinking of getting this beauty for an obelisk in my front yard. Maybe a 5' wrought iron. How often do you think it will have to be sprayed for bs? I'm new to spraying this year.

Maureen, it would have to be sprayed as per the schedule on the fungicide you are using. If using Immunox, then every 7 days. If using Banner Maxx (or Bonide Infuse or Fertilome Systemic) every 14 days. And, it will get larger than 5', but you can control the top.

Yup. In our organic garden it nearly defoliates from blackspot, but does continue to bloom very well anyway.
