Answered

Short story - had to move the bush - 2 other rose bushes - Floribunda's - same food etc have new growth and flowers (one on each side of JFK). All three moved together. All have black spot - been treated. Very humid, wet summer. Replanted in June. Leaves still green. Just no new growth. Canes turning funky brown slowly. Been treated with bayer advanced 3-1 systemic rose care and a copper fungicide. Garden centers here say just wait. Thanks in advance.

    There are so many things it might be. When did you transplant it? Did you bare-root it when you moved it or disturb the feeder (white) roots? How big of a hole did you dig and how far apart are the shrubs? Did you amend the planting hole, and if so, what did you use? After planting or transplanting I generally recommend that no chemical nitrogen fertilizer is applied until after a good first bloom. I amend planting holes with about 4 cups of alfalfa pellets or 2 cups of alfalfa meal, well composted steer manure at a 1:3 manure to soil ratio, and a couple of heaping tablespoons of epsom salts. If I have it, I toss a small handful of super-phoshate (NO nitrogen) and some more alfalfa meal or pellets in the drip zone and water very well.

      @Deborah Donovan-Navarro Thank you - it did not disturb the feeder roots too much, I kept as much dirt with it as I could. Spacing is an issue. I could not place things far apart do to the mess they were making it really was obscene how much they destroyed to put a sidewalk in - see the before and after - the rosebushes were on the left - the side with the railing.

    The folks at the garden center are correct. It's stressed from being moved and needs time to re-establish a new root system. Just deep water if necessary, it looks overall healthy and should come back just fine. Btw, those rose canes are not funky, that's typical for a JFK, I think it may be related to the "mother" variety of rose from which is was hybridized. Have a couple of rose freak friends that have them and theirs looks like that.

    Thank you Catherine. Sometimes the hardest thing is just waiting. The JFK is special for us and it was just the one plant I did not want to lose.

    Get two things plus the deep watering: Super-phosphate (0-5-5 or 0-10-10 or similar. No nitrogen!) and get some alfalfa meal. Be generous using the alfalfa meal around the drip line of the rose and the super-phosphate will help to build the root and stem system. I don't know how you feel about chemicals, but there are 3-way systemic rose food to keep aphids off and prevent fungus diseases of black spot and powdery mildew. Before applying systemic gently remove the already diseased leaves and dispose of them, but do not put them in the compost. Don't miss the fallen leaves! If it's salvageable and you protect it over the winter, it should have a good shot at getting strong and thriving next spring.

    @Deborah Donovan-Navarro please explain. Why would you recommend superphosphate with no nitrogen and then alfalfa pellets which are all nitrogen? Not that I think it's a bad idea, since phosphate really helps the plant to build a strong root system. But I don't get that, please clarify.

    Catherine. Tanya lives in Pennsylvania. Chemical nitrogen would encourage leaf growth going into fall, which you don't want. Alfalfa meal is very slow acting and will do most of its work in the spring. It will do more to strengthen than spur growth at this point. I am a master gardener and served on the horticultural committee and as "rose lady" at a world class estate. I cared for well over 200 roses for several years. In my experience you can't go wrong with alfalfa meal any time of year and putting it in the planting hole is very helpful to settling roses into their new cultural conditions.

      @Tanya L M You might search for "own root" roses for future purchases. They're much easier to winter over in borderline zones. I lived literally right next to Puget Sound in zone 7B and I protected the grafts on my roses with mulch every winter. Most years I didn't need to, but some years we lost all of the standards. Sad.

    Thank you, Deborah, that answers my question. I too happen to be a master gardener, abet a "former" one. Didn't realize PA was so close to the "freezer" zone, although I've lived there for a time, but it was in the southern part of the state. I envy your "play time" with all those roses. sigh Sometimes it's hard to be a rose "freak".......LOL

    Catherine - it is hard for me sometimes to know what zone I am in - we are 2 miles from the lake. I do think the new hardiness zone is better - problem is not everyone uses it.

    @Tanya M, well I think it's going to take some time for the new zone info to catch up with everyone. No doubt the topography of your property is another issue, being that close to a lake is going to effect that somewhat. Besides, the zone maps is only a suggestion, it gives you a general idea so you have a better idea of what will grow best in your area. Once you get to know your ground, you'll know which areas will work best which plants. I'm in Zone 7b, but I have an area that's rather sheltered, so I can "fudge" with some tropicals. I do have to protect them in the winter, but I have a banana tree of which I am so pleased and proud. Fascinating plant, I was amazed.

    Catherine - same zone, but opposite sides of the country. I only grow a few roses these days, as an aging gardener and having recently relocated to a previously bank-owned property. Rehab gardening is my favorite, but other than some very nice Japanese maples, 5 Yakushimana rhododendrons and one pieris, I've pretty much had to start from scratch this time.

    @Deborah Donovan-Navarro looks like you are going to have tons of gardening fun. You pretty much have a brand new, fresh palette to play with. ^-^ I don't know what the deal is with the JFKs but the kinda "funky" looking canes seems to go with it. A couple of my MG friends have them and have the same complaint. Looks weird, but the plants are healthy, and producing bloom like crazy.
