Forensic Science for Rose Deaths?
Now that it has stopped raining every other day, it is so hot there's
no way I'm going to work in the gardens especially since we now have skeeter-born illness here! (I'm a wimp, it's true.) I'm still chewing over what went wrong that resulted in the death of so many grafted roses, mostly the new ones I planted bare root. What has been different this year is: 1. LOTS of rain. 2. No anti-fungal or insecticide sprays at all since mid-May. What happened: I planted around 15 big, fresh, healthy bare roots from S&W Greenhouse, all Weeks and J&P roses in early April. I babied them. They all showed growth and many bloomed. Then inside a month they began dying. They show signs of cane borers, but all my roses with thick enough canes do and always have. (My usual spray doesn't treat borers, I guess.) They died one cane at a time, turning brown and dry. Where they were planted: Nice big 2X2 holes, most in a cultivated bed that I had professionally dug and amended in early 2002. Permatil all around, then rich black soil. No fertilizer. Bud unions set just above the soil surface. The bed is lower than most of mine but drains just fine. These roses never sat in water. Cass mentioned that it might be soil related, some sort of nutrient problem or pathogen, which makes sense--however, in the bed where most died there are healthy, beautiful own-roots that I planted Fall 2002 that are doing wonderfully and never missed a beat, have bloomed their heads off, etc. They are Muncy Austins, Roses Unlimited hts such as Granada, and some Michael's roses. Penelope and Paul Neyron are the only "oddballs" in the group and are going great guns. These roses are planted about ten feet from the dead bareroots, all along a chainlink fence. If anything, the property slopes toward the healthy roses, so they might have had the best chance of sitting in water. It is certainly true that ALL of the roses I planted opposite the healthy ones were the new grafted bare roots, and all are dead. The area gets six hours of sun, at least, some in the morning and some in the afternoon. Any ideas? I can just buy ownroots from now on, but I want to KNOW what did these in. I have had success with bare roots before. Thank you. |

Maybe you should investigate on the rootstock.

Most of the dead plants are still in the ground, as I have only pulled out Arizona. Arizona is the only bare root to die in a front, sloped bed, but was another of the new bare roots. Do you think I ought to pull the dead ones out to look at the roots? Arizona's looked just like they did when I put them in. Except dead, not just sleeping! Jocelen. "Shiva" wrote in message s.com...

They died one cane at a time, turning brown and dry. I'm as stumped as you are. This is all guesses. Could have been a terrible case of the canker that infested so many roses in California this year. I'd pull those puppies out of there just in case. That stuff would cause the cane to blacken and die back from any cut ends. It was bad this year, and it was insidious. When I bought my second Outta the Blue, it was a big, healthy, fully leafed-out plant with lots of bloom. But when I was deadheading, I found cankered ends of canes right in the middle. By then I knew how bad it was and pruned very hard. The plants grew and grew and flowered non-stop. I just repotted by my Outta the Blues and found more canker creeping down the sides of canes. So even with a new long cane 18 inches long, I found canker on the off side of the basal -- and the canker had extended below where the 18 in. cane broke from the basal. Once again, I cut it all out, well below the canker. Believe me, you wouldn't know a thing was wrong with these roses by looking at the bloom and foliage. Oh, and I went nuclear this spring and sprayed with everything I could find that might have some impact on canker -- macozeb, Compass, Junction, wettable sulfur. I never saw a bit of improvement or even arrest. The only thing that helped was a hot, dry spell. Where they were planted: Nice big 2X2 holes, most in a cultivated bed that I had professionally dug and amended in early 2002. Permatil all around, then rich black soil. No fertilizer. Bud unions set just above the soil surface. The bed is lower than most of mine but drains just fine. These roses never sat in water.

Penelope and Paul Neyron are the only "oddballs" in the group and are going great guns. Are the oddballs part of the batch of BR's, the remainder of which died? I don't understand. These roses are planted about ten feet from the dead bareroots, all along a chainlink fence. If anything, the property slopes toward the healthy roses, so they might have had the best chance of sitting in water. It is certainly true that ALL of the roses I planted opposite the healthy ones were the new grafted bare roots, and all are dead. So this is one big raised bed? What is the retaining material? Doesn't NC have a county extension that does free or cheap soils tests? What do you have to lose? Was soil imported for the bed? Pull out the dead dozen and see if you find anything of note on the roots. Or even if they have roots. |

It sounds to me like a case of drowned roots. If the bare roots were planted in March and the rains immediately started and didn't stop for months, then the bare roots would have never gotten the chance to breathe (literally) and grow properly. Established root systems would grow far deeper and more extensive and could probably thrive in such conditions. However, a one month old plant doesn't have any roots deeper than about 2 feet, and at that depth *all* of the soil would be sodden. Just my two cents... |

My drainage sounds worse than yours, having predominantly clay soil, but I've found that a little moisture is much better than a lot. I've got (possibly) some marginal benefit by using plant starter solution on my new plantings. Having said all that, it looks like my bare root Benjamin Britten and Ernest's Blue roses are going to suffer infant mortality. This I blame entirely on the supplier, who shall remain nameless for now. The bushes were too tiny to be 2 years old - a case of rushing new varieties to market, I would suspect. Their root systems were barely there. Not happy.... |

Dig them up and look at the roots. I suspect that they will show that there
was not any new root development. This can a result of several factors the first being rain and saturated soil, another is that the root stock was damaged by handling and transportation from the grower. Dr. Huey is a very hardy root stock, if you dig them and find that the root system is healthy, the grafts were probably damaged and they existing canes simply used their store of food and then died. Again this is usually a result of poor handling. Examining the root system will most likely give you the best indication of what caused the canes to die. Tim |

If, in general, the subsoil gets even wetter than the topsoil because that's where all the water drains *to,* how do you explain that? And, even large roses tend to have the vast majority of their root system in the top 2 feet of soil. None of that changes the likely cause. Oh, and I never put bareroots right in the ground. I lost 7 or 8 one year due to dessication from high winds in March. Now I baby them until they are big honkin 5 gallon plants. I can control water and drainage until they're ready to take it on their own. If a pot isn't draining, I knock the rose out and repot in different topsoil in a larger pot. |

And.. I'm still surprised that she didn't see signs of stress in the established plants in the ground. Having seen the volume of rain that those folks got this year, I doubt that the word drains really applies. As far as I know, it was literally raining just about every day. We got tons of rain, but we seemed to have periods of dryness in between (and I don't think that the eastern seabord got much respite - it always seemed to be either raining or drizzling). It was almost perfect for our lawns. I don't think I had to water *once* during June and July, and this is almost unheard of. Of course, now, we're in the dry, hot dog days of August, although we got a much needed cloudburst last night. If, in general, the subsoil gets even wetter than the topsoil because that's where all the water drains *to,* how do you explain that? And, even large roses tend to have the vast majority of their root system in the top 2 feet of soil. I'm thinking that with a larger root mass, there's more of a chance to get *some* oxygen exchange - plus, there's some acclimation that's in play (almost one of those elusive "life force" issues - the more established the plant, the harder it is to kill it with the same conditions that affects younger, less-established plants. (hey, I'm jus making some uneducated guesses here). None of that changes the likely cause. Oh, and I never put bareroots right in the ground. I lost 7 or 8 one year due to dessication from high winds in March. Now I baby them until they are big honkin 5 gallon plants.

Nice roses. You put 3 in a wankle engine shaped bed? And I really like that site for posting pix. Loads fast, easy to navigate. These bare roots went directly in the ground the day after Memorial Day of this year. They obviously performed beautifully. Many people *do* put them directly into a nice prepared prepared bed. I don't do it here because late bareroot season here coincides with seasonal winds that last for 3 weeks with no rain right after the rainy season. Soils are still cold, so it's hard to get roots growing in the ground. Young plants crisp up fast under those conditions. OTOH, a pot allows the soils warm, the roots to grow, and the rosarian to closely monitor a number of roses in a single location. |

Nice roses. You put 3 in a wankle engine shaped bed? Why yes I did. Great pickup (you, not the RX-7 g). And I really like that site for posting pix. Loads fast, easy to navigate. I do too. It used to be free, but he's finally had to start charging. $22 a year for 100 mb. I've currently got about 160 mb online and I haven't been limited or charged extra. It's actually a "photographer's" site, not an on-line storage site. Lots of great photographers have galleries there. I basically use it in lieu of a personal web site to post photos (mostly for sharing pics with others, not showcasing my awesome photography skills g) I also like the fact that you can post full sized photos as well (not being limited to a certain size like at some online photo sites). I downsized all of my rose shots simply because I knew that I was out of room. These bare roots went directly in the ground the day after Memorial Day of this year.

OTOH, a pot allows the soils warm, the roots to grow, and the rosarian to closely monitor a number of roses in a single location. Have you ever done the mounding thing with bare roots? I'd think this would offer sufficient protection from wind and dryness. I've always had great luck with this method. Having saidthat, one should do what one is comfortable with and what works in their climate. The frustrating thing about mounding is wondering how they're doing under the mulch. But it's really cool when you finally uncover the plants. One thing I *didn't* do that I always have done in the past is cutting the first buds. Usually with hybrid teas, you get one or two buds, but in this case, the first flush all happened at once and I got over 30 buds on the three plants. I figured that the plant knew what it was doing chuckle. I'm guessing that I'm going to have one more flush before it's all over. The downside to such massive bud growth so early is that when we had a big rainstorm a couple of days ago, it caused weepy blooms the next day (because there just isn't the substance to the stems yet). Boy, I really like this plant a lot. |
