Hi, I just bought a bareroot grafted Cary Grant 2 weeks ago. Few days ago I noticed one of the cane near the bud union turn black & is spreading. What is it and what should I do? Is it caused by virus or bacteria? Help me, I don't have much experience with roses.

tomatoes with Mosaic virus/tobacco virus
Comments (10)I disagree... herbicide damage rarely causes spots on the leaves, and the yellowing tends to be a general overall thing (especially on the growing tips), not mottled. It's always easier to figure out with a picture, but a virus is possible. TMV is, indeed, almost nonexistent outside of labs in the US. Cucumber Mosaic Virus, on the other hand, is out there, and may be more common than you think (many Heavenly Bamboo plants carry it; the resulting red color is considered desirable). There is also Tomato Spotted Wilt Virus, which is rampant in many parts of the country. Both CMV and TSWV are vectored by insects; they are the major viruses we usually run into in tomato plants. They can strike individual plants, leaving neighbors alone. If you're dealing with an herbicide, the effects will show up on neighboring plants which are close to each other and sharing the bed, or different species of plants that share the same soil/exposure, like squash or peppers (but not necessarily every kind of vegetable). The plants might pull out of a light exposure once the source of herbicide is removed; the best sign is when they start to grow again. Badly herbicide-damaged or virus-infected plants will stop growing or slow to a crawl, and will never start again. Am I stuck with never using this soil for tomatoes again? No. Any virus you are likely to encounter in tomatoes doesn't persist in the soil. If your soil is contaminated with herbicide (and I can't imagine how you would manage that with Mel's Mix, unless the compost part was badly contaminated) then you will have to get rid of it, but not if the herbicide drifted over from elsewhere. How badly will my harvest suffer? Virus-infected plants will not bear, or will bear misshapen and often bad-tasting fruit. Since you're not likely to get any good fruit out of these plants once the virus is well established, you'll have fewer plants to harvest from. If herbicide-damaged plants recover, they will be set back by at least a few weeks, but the fruit you get after that should be fine. Is moving the plants to a different part of my back yard sufficient, or do I need to destroy them? If it's a virus, you need to pull them. CMV and TSWV are transmitted by insects which can fly, and infected plants can serve as a reservoir for insects to infect your currently healthy plants. (Besides, they won't fruit well, so why keep them?) If it's herbicide damage... well, if the soil isn't the problem, and there's no new drift from elsewhere, then there's no real point to moving them. Either they'll pull out or they won't. How likely is it that all my tomato plants are infected? I have around a dozen plants and hate to think that I need to destroy them all. I've gotten a few virus-infected plants over the years; once I confirm that it's a virus rather than some quirk of weather or genetics, I pull the (usually single) plant and look for the same symptoms on other plants. Out of three years I've had a virus problem, I've had to pull four plants total, and I grow over 15 plants a year. So keep your eyes peeled, and if you're lucky, it might turn out to be just a couple. They're all growing well. Now this is what confuses me. Is it just the normal-looking plants that are growing well? If so, cross your fingers and leave them be. If the shoestring-leaf ferny plants are also growing "well", as in vigorous and putting out lots of new growth, digdirt may be onto something with his herbicide theory.

Comments (13)Anthrax and Botulism are both caused by soil-born organisms. They are probably in every garden on the planet. Has your child had chickenpox yet? That's a Herpes virus that attacks the nervous system and remains alive in your nerve tissue for life. Look forward to the neurological conditions it can cause forever, especially if your immune system is depressed by excess worrying. The fact that there are millions of other species in the soil, taking up most of the space, eating the microbes that make humans sick, is the safety factor. Getting an assortment of harmless germs on your hands and breathing normally, I argue, is safer than walking around a hospital or working in a crowded office. That's where there are high concentrations human-specific pathogens. Sanitizing everything in those areas also eliminates most of the competition that keeps the bad germs in check. Your garden is your happy place, not your mortuary. I have a worm bin. A large one. I'm worried about inhaling the powdered lime and the rock dust that I put in it and on the garden, but my only negative reaction to my worms is the 'gross' factor. I regularly harvest buckets of liquid that drains from my worm bin so that I can water plants with it. Pouring it from the bucket into my little watering can normally results in getting some on me and everywhere. Not dead yet. My dog drinks the worm juice when I'm not looking. The only days she acts sluggish or sick are after she gets her shots at the vet. After playing fetch with her for a while, I sometimes rinse the slobber off of my hands in the bucket of worm juice. (I do rinse them in the sink once I get back in the house though) I think the last time I got sick was in 2002. I was in Army basic training, under a lot of stress, sleep deprived, and sharing space with people from all around the country. People carry disease-causing germs in concentrations that can cause disease in healthy people, healthy soil does not. The stress of worrying about disease is arguably more harmful to your health than dirt. Humans have been farming by hand for something like 10,000 years or so before the queen of England declared she takes a bath once a week and thus made wash tubs common household items. Germ hysteria has probably done more to harm human health than guard it. Here is a link that might be useful: Chicken Pox...See MoreTrojan Virus - Causing Major Problems

Comments (1)You have not posted any substantive information detailing your water conditions or the model number of the 3M filter that was recommended for treatment of the water conditions you haven't specified. We can not speak intelligently regarding water treatment without the results of a water test by a certified lab. A water treatment company that pretends to should not present itself as professional.
