The twisted new growth has powdery mildew disease, which you should look up. You can control it by hosing down the foliage occasionally at a time when it will dry quickly and applying an organic fungicide such as oil, sulfur, or Cornell mixture. See the FAQ on the Organic Roses Forum. The large brown areas appear to be some type of spray burn. Have you applied anything to the foliage? The round brown spots could be spot anthracnose disease, to which Therese is susceptible. It spreads in cool weather with rain, but you may not need to do anything about it. TB is a tough rose.

Countryrose, those are some splendid photos. I have both "sisters" growing near one another. Therese is quite prone to attack by rose stem girdler and so she does not get a chance to reach her full potential but is constantly trying to grow new canes to replace the ones I have to prune away; she reaches about 4 ft. maximum. In spite of Therese' lovely reddish canes, my heart goes to Marie. The purity of her white petals is heartbreaking - and those red accented buds! Ahhhh, so beautiful. She is extremely diminutive here, being only about 2' tall. I have to get down on hands and knees to appreciate Marie's beauty and fragrance, growing there at the foot of her sister. If there would be any resistance to deer, BTW, it might be that she's so small they would overlook her in favor of more upright browsing - like Therese! ;-)

I'm not sure what's up with your Theresa Bugnet rose, though good soil and adequate moisture would help to induce further flowering. Mine continues to bloom on new wood, though nothing spectacular after the spring flush ... otherwise, this is a favorite of mine! Terry

Hi, my name's Tricia & I read through the Northern Forum a lot but rarely post here because I live in Connecticut now. But, I have some experience with the roses being discussed here from living in New Hampshire & so I thought I'd make a post. Hope nobody minds. R. 'Therese Bugnet' will naturally grow into a vase-shaped form with her canes arching up and over. She's never, on her own, going to look like a stout, bushy rugosa...she's got much more grace than that. She'll need about an 8' circle of real estate to really strut her stuff. The canes will be held off the ground enough you can plant small ground covers (like geraniums) at her feet & she looks wonderful. Since she's an early bloomer...she often experiences heavy rains while in full bloom. I have found that her flowers are remarkedly sturdy...I just gave the canes a good shake to get rid of excess water & left her alone. A couple hours later the flowers were always looking pretty good. R. 'John Cabot' (Canadian Explorer Series) is a much larger rose than R. 'Therese Bugnet'. 'John Cabot''s natural form is also to grow tall & then arch over. It's even more robust than R. 'William Bafflin'! To let this rose do its natural thing...give it about a 10-12' circle of real estate & just let those long, wonderful canes grow up until gravity takes over & they gracefully arch over towards the ground. It's a stunning sight in full bloom! It'll naturally grow to about 8-10' tall. OR, 'John Cabot' can be trained to be a quasi-climber. It will require a tall, very sturdy trellis because this rose throws LOTS of canes each year. The canes will still have a tendency to reach for the top of the trellis & arch over the top. I had an old clothes line in my back yard...we removed two end posts & attached a swing to the other set of posts. Planted a 'John Cabot' at the base of each post. In four years, both rose bushes had grown to the top of the posts and arched over the top pole...draping the swing in roses for two glorious weeks in June. Right after bloom, 'John Cabot' begins throwing new, vigorous canes. Tie these up quickly because they seem to harden off faster than most roses & become difficult to work with even just after a couple weeks. If you are allowing your 'John Cabot' to grow naturally...every year (starting with year 3), prune out 3-4 of the oldest canes at the base to keep the shrub vigurous. If you have an "own root" shrub & experiene winter die-back...you can cut 'John Cabot' to the ground each spring & it'll regrow to about a 4' shrub each season assuming about a 100 day season. Like R. 'Theresa Bugnet', it's natural form though is NOT bushy, stout, & short. Think something more like a natural (unpruned) forsynthia that has been allowed to grow unmolested by pruners (although, of course, a rose will never be as dense as a forsynthia)...and that's the effect R. 'John Cabot' has in the landscape. Hope someone finds my experience useful.
