mersiepoo, I trust you "are" remembering that a raspberry "cane" lives just two years: normally and without special drastic pruning, a cane comes up from the roots and makes a full sized cane the first year ("without" berries the first year unless it's an "everbearer" or fallbearer type), then this cane lives on into its second year whereupon (if all goes well) it makes fruit, and Then_this_cane_dies. If it fails to make any fruit (like yours, from what you say) the second year, it presumably dies anyway. Probably I could have explained this better, but maybe you will know what I mean and what I am getting at: the fact that your second year canes eventually die (if I understand you right) during that second year, especially during the latter part of that second year, would not be anything unusual or abnormal in itself, or necessarily initself a sign of disease: but the lack of successful berry production does seem like a sign of disease. To hazard a guess: these raspberries you have might be some kind of black raspberry, and , reminiscednt maybe of the situation with red raspberries--wherein red raspberries also come in a yeallow version--well black raspberries also have a yellow berried variation, really more a gold color in my experience and not the same shade as the "red raspberry yellow version." The gold or yellow version of black raspberries is, in case that is what you have (and I think your vine descriptions do fairly well match "black raspberries") I believe is, as found, almost always wild black raspberries/gold variant (there "are" cultivated versions of the gold variant of black raspberries, but from what I understand they're so obscure and rare, that the chance of coming upon them in a planting or a backyard would seem exceedingly small). "And", black raspberries in the wild, from what I've experienced anyway, can be very disease prone as to the berries, with the blossoming and the berries sometimes seeming to start out fine, but often drying up and dying (the beries I mean,) often during ripening or just after ripening. As in, the whole plot. Not normally one of the really serious diseases such as kills the plants or threatens the existence of other nearby ones such as the other ones of other types that you have, but might best be kept an eye on incase similar berry problems start ashowing up on your other raspberries (in which case, probably definitlely consider rooting out the mysterious ones as they might, then, be well suspected of beding the cause. Meanwhile, if you keep them, maybe good for wilflife cover or something? Your call of course, as to what to do with or about them and as to your priorities

Thanks Chris- I really shouldn't chuckle because it is better to be safe than sorry. When I moved down to the prairie here and we had all this buckthorn on our property I thought it was the beloved chokecherries that we had always made jelly from on the farm back home. I popped one in my mouth and had to spit for 10 minutes to get it off my tongue- now I read that they can cause severe gastric upset. Berry picking in the woods from blueberries, strawberries, blackberries, highbush cranberries, chokecherries etc. is a fond memory of my childhood...I'll never forget the glass quart jar full of water that we all drank from and my brother and sisters all yelling at me for picking and eating more than I put in my pail.

ask in the fruit forum ... if you want to perfect growing such .... could have been winter damage... mine took a severe hit .. many plants died ... are they in full sun??? what is tempo [cant google such a general word] .. is it listed for berries.... and why did you use it.. if you didnt know what the problem was ... and you are aware.. that cane are biennial.. right???? ken

I temporarily planted some in my cottage garden, with the intent of putting into a permanent bed. Well, I did transplant them. But, they do not produce enough fruit to be worth the trouble. No matter what I did, not much fruit. I got canes canes canes and more canes and healthy too. But not much fruit. And the horrible thing is.... now I got canes coming up alllllll oooooooooover my cottage garden and cannot get rid of them all. Worse than Johnson Grass they are. Go and buy good healthy domestic canes. Those produce fruit. PVP
