Man Made Global Warming? The 1975 Time Magazine had that famous (infamous) cover about Man Made Global COOLING..And as Mzstich mentioned, there is another pesky little fact about the "global" heat wave period during the middle ages that has yet to be rationalized away....There are real things to worry about. I'll not loose any sleep over this one, but you all go ahead.........Maryl

Henry...

Another alarmist title ... meh.

I guess we can plant these roses in our gardens to let us know that conditions are getting right for spider mites to be active. Kind of like a "canary in the mine". Right now, I have deVink's 'Cinderella' performing that task. If I see and incipient spider mite infestation on that rose, I know it's time to start washing my roses down to both cure the infestation on 'Cinderella' and to avoid infestations on the other roses in the garden.

Thanks for adding to the list of roses that can perform the same function.
Smiles,
Lyn

I have been fighting spider mites!!!!
Will they destroy the tiny new growth when it first pops out from the bud-eye?

I will get some pics tomorrow in the daylight.

About rose midge - This insect is less than 1/8 of an inch long; it lays eggs on new growth and under the sepals of buds. They hatch and feed on the new growth causing it to turn brown and die. Buds don't develop. In about a week the midge falls to the ground and emerge from cocoons as adults to start the cycle all over. There won't be many blooms in a garden with midge as most of the buds will be destroyed. The first sign of a midge infestation is a tiny crisp, burnt like piece of foliage at the tip of new growth. Also, the very top leaf is usually distorted.

Here's a link to Baldo's site on rose midge with some pictures. It is an old page as it mentions diazinon as a treatment, which has been banned, but the pictures are helpful.

Oregon State Univ also has a good page with pictures and more up to date treatments-

http://oregonstate.edu/dept/nurspest/rose_midge.htm

A friend of mine has rose midge; she didn't want to use a chemical control so destroyed most of her roses hoping to replant in a couple of years. the cultural controls she tried didn't work for her. Also, there have been some discussions on rose midge here as a number of people have dealt with it. If you search you can find old threads discussing it.

Disclaimer: I know the above only by reading, I've not seen it myself. I've also read pesticide burn can look like rose midge, but that's probably not a problem in your garden? Gean

Steve, thank you, that's exactly what I needed to know about the canes.

Kippy, I had not seen that one! You're right, the color matches Purple Splash perfectly. Since I can't find an HT purple maybe a Stormy Weather/Purple Splash/Stormy Weather trio would give a pleasant affect.

Thank you!

Big Lots! I get a lot of my gardening stuff there because they're prices are very reasonable. The metal ones with 4 wheels work the best, I think. They last for a good 4 or 5 years before they break and need to be replaced. The wood ones are cheaper but they don't last as long and don't bother with plastic ones because they don't last for even one season before breaking. Besides they don't allow for good drainage because they hold water in them.

Wheels bow and break on my metal ones. Got some from Arizona pottery, made of heavy duty plastic. Expensive but hold up to 500 lbs. thanks, Seil. Will try big lots .
And old school, I just take a milk container bound for the recycle, with me. Snow can work too.

Cadence, you can read labels and look for the active ingredient potassium bicarbonate. It is sold under many names in the USA. I'm sure it is available in Canada, as it is no more hazardous than baking soda.

Spinosad can spot leaves...
Both of our Carefree Sunshine roses were spotted by spinosad...
Always do spot testing before applying to entire rose bush...

A university soil test through your extension service should be pretty dang accurate.

Nematodes and PH are definitely possible culprits. Other possibilities could be soil history if you haven't lived their long. A previous owner could have dumped something in that soil that wouldn't show up on a standard soil test. Common culprit would be thats where they parked the car when changing oil/flushing out antifreeze.

My roses are grafted onto fortuniana. Though I have some old roses that do well here own root but not in this area. So nematodes shouldn't be as much of an issue. Other plants do well here in the soil with nematodes, but again not in this area. We've lived here for 14 years. This bed used to grow gorgeous roses, but not anymore. Michael good suggestion on the kitty litter.

Hi View1NY, well, I cut them back hard today and buried them in a pot with a good mix of potting soil and my own organic compost. We'll see who comes back!!

Yes, I bought them on ebay from a seller named Rio0776 out of California and I was extremely impressed with the size and health of the plants when they arrived and how long they lasted during my negligence!! :(

He's out of roses for this season but I've got him saved as a favorite seller and really don't want to buy from anyone else. The rootballs were substantial and full of good soil, and the rootstock is so fat and green on his plants and the shoots had new growth right away. I'll buy again and again from him no worries.

eco, thanks for the info. I saved that ebay seller so that I'll have it handy when I make my spring order.

Have you ever ordered an own root rose from that seller? I'm in Brooklyn NY & my climate is pretty similar to yours. The roses I have are all grafted onto Dr. Huey & was thinking about trying an own-root rose next time. I'm curious about how it would do but really don't have the patience to wait years to see a decent-sized plant. Any info would be appreciated.

Sulfur kills or repels bad spider mites (Two-Spotted Mite) as well. I never had a mite outbreak during the years that I used it. However, the TSMs can develop resistance to sulfur, and then you have a big problem because the sulfur suppresses the predatory mites that normally help control the TSM. This commonly occurs in agriculture--not so much in home gardens, but it is possible.

As Nicki says, potassium bicarbonate (Remedy, Green Cure) is probably a better choice for powdery mildew on roses. But sulfur is also somewhat effective against blackspot and rose rust.

Hi all, I'm new here but I'm buying some late season potted roses and cant decide between some beautiful orange and multicolor ones for here in NJ. Can anyone advise on these?
My color scheme is mostly lavender/mauve, peach/pink and white with some deep pink/purple and orange accents.

Chihuly floribunda, George Burns floribunda, Easy Does It floribunda, Living Easy floribunda and Joseph's Coat climber, Polka climber...which of the 4 floribundas (cant decide between Easy Does It and Living Easy) and 2 climbers do you think I should choose?

Thanks all!

Hi eco--you would probably get more responses if you started a new thread and asked your question.

Sorry I can't help you--haven't grown any of those roses. I like the ideas you are working with, however. : )

Yes, of course we have all seen pictures of what someone thought was RRD only to inquire and find out that their gardeners had been spraying weed killer all over. At least there is a test for RRD - thanks.

In addition to the possibility of herbicide spray damage, I feel that the public needs to be aware of the possibility of herbicide passage through the soil, i.e. rose roots absorbing herbicide, see link below.

I got the Black Cherry Floribunda and Monkey Business from J&P a few weeks ago as well and although they were large cuttings, they were still bareroot cuttings.

As long as the roots are hardy then they should survive but when I planted J&P roses last year late in the year they struggled the following year (my Disneyland is barely over five inches tall this year). I would make sure the ground is mulched around them. You didn't by any chance plant them next to the house did you? That would increase their chances due to protection from the wind and some warmth radiating from the house.

It says a lot about the quality of the new J&P that they sent these out to such a cold zone this late in the season. Most good nurseries would have set a date for shipment next spring. In your zone these are going to be very hard pressed to survive this winter. I know that Mad is correct that heavy mulching can cause disease problems but personally I think it's the only chance these have of making it through your winter.

Hopefully you planted them deep. Even if they are own root plants deeper is better in your zone. Instead of mulching with leaves I would suggest mounding them as high as possible with soil. You can actually bury them completely, like they do when they do the Minnesota tip. If you do this make sure that you put markers around them so you know where they are and can find them and unbury them come spring.

I don't ever recommend keeping roses in the house. It's a very tricky thing to do. They need much more humidity than a normal house has and even with lights they won't be happy. They also tend to have terrible problems with spider mites as well. If they were still potted I would suggest getting one of the small free standing green houses to put them in, outside, for the winter. The green house was very inexpensive at Big Lots (you can also find them on line this time of year) and I've had very good results with doing this with my seedlings and new cuttings.

I wasn't there at the start but I know you have gone to extraordinary efforts to understand this disease and help others to diagnose and limit the spread of RRD. I hope you see it dying out one day. Thank you for everything you have done.
