Hi Lauren. Well, I sure hope viewers are also checking the comments, because this is a very good point. I'll pin this to the top of the comments section to improve the chances people see it. I've been basing my assumptions on older research (where it was thought insects and pruning tools were a major factor in spreading the disease), and it seemed to make sense to what I learned in hort school about virus transmission - so I hadn't looked up the newer studies. My fault. Some university and college fact sheets on the virus still warn about those causes, so I don't feel so bad. But then, most horticulture departments are pretty cautious anyhow - I recall that they wouldn't let students who were smokers handle the tomato plants without fresh gloves because they said it could transmit TMV from their cigarettes. In my case, I'm still going to err on the side of caution for a couple of reasons: 1) I'm a commercial supplier of roses, so the consequences of being wrong are higher for me, and 2) it would be pretty difficult to design a study large enough to rule it out entirely. The virus must have had some mode of spreading in nature (prior to humans mucking about with bud grafting) - and root grafting alone as a mode of transmission would have kept the virus(es) constrained to quite a local distribution. For those seeing these or other RMV symptoms on plants in their gardens, though, I'm going to backtrack on my recommendation in the video and say that if the markings don't bother you, and the virus doesn't seem to be impacting garden performance significantly, AND you're not using the plant for propagation, then you might want to keep the rose. It looks like the risk of spreading my hand tools is lower than I thought (but please still clean your tools!)

Fraser Valley Rose Farm Ok, that makes perfect sense to me. I also read that RMV is more of a symptom of the “type” of virus and that there are many viruses that cause mosaic in roses. Not sure how true that is but either way yeah I’d say there isn’t near enough research to make that large of a gamble (for folks like you) and if I had roses in my collection that were more difficult to get my hands on I would be more cautious probably. Apparently there are some suppliers that at least in the past have been notorious for propagating diseased roses and the rose that is showing symptoms is an Alfred Sisley I bought from Walmart a few months ago. It’s really pretty and I couldn’t find any accounts of the virus spreading from infected to unaffected plants so I’m ok with rolling the dice. If it does spread that’s at least valuable info I can share.

Thanks for the encouragement!

My pleasure George.

My pleasure Barbara

Thanks for the information, very usefull. 1:29 time for a new jacket?😜

Great approach. Thanks Prajakta

Thanks Andrea

My pleasure Helen. Thanks for watching

Thanks so much 😊

So nice to hear. Thanks for watching.

Happy you figured it out!

Thanks. I know a couple of people who took their horticulture training through U of Guelph, and liked it a lot. They have online courses too.

Thanks!

Thanks for pointing out the concern with chlorine and metals in the water supply. Definitely worth considering your water source.

Aw, thanks.

Thanks for the feedback Marcy - I'm glad you find them useful!

Thanks Jon

Thanks Chris

Thanks!

Thanks - yes, some of the symptoms can be pretty similar. Happy to hear it turned out okay for you

Just east of Mission BC Canada

Good to hear you've nailed down the problem!

Sure thing

If it's in a pot it's far easier to check - in the ground, you can always dig down into the surrounding soil to check for overall soil moisture.

Thank you

It's pretty hard to know what specific nutrients are missing without soil testing. It could be iron - or just as easily be nitrogen or magnesium. If a dose of iron helps to green it up, that'll help to confirm the info.

Yes - a test hole nearby the plant will give you a good idea of soil moisture.

Hi Rossanna. I mad a quick video on it: kzfaq.info/get/bejne/ntlplsaEluCXYJc.html The basics are a very pronounced discoloration and growth distortion, often quite local to one branch on your shrub.

Thanks!

I think you could be right with the overfertilization. I've overfed my tomatoes, and found the leaves went darker green, and the plant stayed super compact.

Repot or rinse with water repeatedly.

@@FraserValleyRoseFarm Thanks so much!

Hi Lila. When I hear white spots on roses, I think powder mildew (check google images for confirmation). It's a fungal infection, and you can do some good by thinning the growth of your roses to allow air circulation to the inside. A consistent supply of soil moisture also seems important. Little holes could be a lot of pests - beetles will punch little holes in leaves, but also snails. Unless the damage is severe and progressive, it may not be worth tracking down.

White spots can be mealy bugs also. Zoom in and see if they are bugs..

@@FraserValleyRoseFarm Many thanks for the reply

Hi Enoc. It sure is one of the causes - too much water or poor drainage can make the plant susceptible to root rot. Poor roots = poor uptake of water and nutrients.

A little bit of yellowing or dropping of lower leaves shouldn't concern you too much. \It's pretty natural for the plant to favor the top growth in distributing nutrients and moisture.

Yes, I'd generally say that own-root roses of the same age will be smaller and slower growing than grafted roses. The problem with yellowing as a symptom is that it mean either thing: too much, or too little. It seems that your climate has been cool and moist, and you have them on a similar schedule as more established roses, so I don't suspect they're too dry. If they've been too wet, it will manifest as root rot. Water in a container can remain too moist even if it's bottomless - the plant may just be having difficulty using up all the water in a large container in its stage of growth. I'd probably back down the watering for a bit, but it's hard to say from here. Also just make sure that it's not overfertilization.

@@FraserValleyRoseFarm thank you Jason, I'll cut it down and will use a moisture meter before next watering. Thanks again

Hi Faye. I haven't grown lemons myself, but I had a quick look online and it still comes down to the same basic questions: are the roots healthy, are they getting an appropriate amount of water & nutrients, is there some other stress or seasonal change that would explain it?

And another thing how do you deadhead clusters of roses like the knockout roses have thank you
