One more item whivh may or may not be related. These white specs were showing up right after I planted the rose next to it.

I do not see any visable bugs on plants.

Black fuzzy on leaves is black spot. White spots is ”Saw Fly/rose slugs.” Tge dots start as egg areas & grow into rosecslugs-look like little green catipliiars then turn into daw flies after eaten holes in leaves.

Remove all leaves with saw fly white dots (egg areas.) Spray for insects afterwards in esrly morning ir in evening whennsun is not sining. Bugs eat holes in keaves at that time-& you need to spray on bugs to exterminare.

Remove all black spotted leaves, dispose of them , then spray what is left of rose bush. Fungicides prevent BS not cure it. .

Hold on, hold on...that's not black spot, those hundreds of dark spots mostly around the leaves' margins, with leaf edge curling! That's a sign of magnesium deficiency. Liquid feed with Miracle-Gro All Purpose as directed on the label for the rest of the growing season, tapering off in September, to no further feeding past Oct. 1.

Don't remove any foliage. Let the roses retain their foliage as long as they please, damaged or not.

Also mandatory, do a systemic spray of Bayer Complete Insect Control....that zaps everything that chews or sucks roses (except spider mites....no evidence seen there, so far), so: rose slugs, downy scale insects, fuzzy aphids (really nasty), etc......are history. Three sprays, two weeks apart should do it.

I dont know if you could tell from my pictures but the dark is actually tiny black specks. The underside of leaf look fine , no specks.

Moses how about Epson Salts? I used to add that each spring but read that it was not necessary.

This is a new garden, with all new plants, at new house, in new city so beds will need time to develope. Ha…Hope I live long enough to see...

Where are you Austin? Your climate conditions reveal much towards getting a correct diagnosis. If you can go back to your introductory, 'Austin,' and add your agricultural zone, closest big city, climate description, like: Mediterranean, with wet winters and hot dry summers, or northeast USA, hot humid wet summers & cold snowy winters, etc..., it would help greatly. My advice may not be pinpointing your problem. I know NE USA issues pretty well, but elsewhere......no first hand experience.

I sm in zone 9 Houston Texas. In the high 90’s this week and last 2 lot of rain and humidity with mosquitos and blazing sun between. I looked up Magnesium and my leaves have more relation to it than the other deficienties I saw picturs of-but ….not quite. i know it is not black spot 50 yrs of rose growing in wet weather confirms my ability to recognize/ we dont get rust down here in heat or not to my knowledge anyway.

Moses those are black spects rather like pictures I see of rust that are orange. Never had rust so going on pictures. Back of leaves do not show back specs.

looks like someone sprinkled pepper on them.

Agree the pattern looks like some sort of nutrient deficiency and not a fungal disease I have ever dealt with. Austin since this is a new place you may want to test the soil and see what you’re working with for any future gardening.

I am not an expert on spoil. I just add Mills Magic + all those other recommended items in Feb-March and assume anything lacking will be handled. Many products have been suggested for soil enrichment over the years, a few seem to be going in smd out of favor.

I thought I would spray a product containing spinosad like compose. Rose will be weak so it wont hurt and in the least will be a preventative

. i have not gotton my eco balance yet so feel I am lacking the good guys. . i think Houston is the ecocenter for all bad the bugs.

I have fought Rose Roset in Dallas, chili Thrips last August when I moved that attack my gav potted brought from Dallas. Now this wierd occurance. It may be enough to turn me to tropicals that love this climent.

😬🙀

Spider mites damage?

Has anyone dealt with veinal chlorosis.? I read that the yellow veining on my leaves could be that. I have not sprayed any weed killer / a possible contributer for the yellow veins. according to google.

still searching for answers??

Austin,

Do the Miracle-Gro I recommended. What have you got to lose? Then do the Bayer insecticide I recommended. Spinosad works in the movies, but not in real life! 😁

I checked with The Compendium of Rose Diseases and Pests, 2nd edition. On page 49 it says the manganese toxicity can cause small black dots on the interveinal areas. I believe that is what your photo shows. In other words, a nutritional toxicity (too much manganese), not a nutritional deficiency.

I do not know what the remedy is, but at least this might be a starting place.

You are a doll rosefolly!! I have been searching everywhere for literature with info. Your source needs to be top of my list. I will search this out but it looks more encouraging than anything I have found. Guess the epson salts will be saved for feet snd bath. Sure glad Amazon delivery has been delayed.

Rosefolly- Amazon has a 2nd eddition for $250. snd I located a site selling a 3rd edition for $175. So do you feel book is worth the $$ ?

neither are available as a digital.

The $250 amazon is a paperback.

I will purchase one if it is worth it…. Not sure why so pricy but I will consider worth the price if it has hard to locate information. Google has only given me basic stuff when I search.

Could you check at your library?There's plenty of excellent information at .edu websites. Check out the Google searc above. Good plant culture with mulch etc. helps with Manganese bioabailabiolty.

Good idea, library has too many homeless these days for my visit but Sure I can find other source or just order book.

Hmm. I guess we dont have that prob at my local. however, I generally get ebooks from my library. Very simple and easy to do.

I very much appreciate the time everyone has taken to respond. i was lost on this and everyone has been most helpful. Thank you

Rifis you are correct that looks like my problem. This is a HUGE help. Ha, I probably should have had soil tested before I bought this house.

At 80 this will be my last garden so happy roses is importaint to my happiness… ♥️

Rifis, that's a great, very comprehensive article that everyone should read and save for future reference.

Austin, I bought my copy back when it was still in print. I don't remember what it cost but I do remember that it was quite expensive even at that time. Still it was less than you are seeing now.

As to whether it is worth it or not, I cannot say. It is authoritative, less than 100 pages but each page densely packed with information. I believe it is meant for horticultural and plant disease professionals, not for someone who is merely serious about growing roses. I bought it because I am a former librarian and lifelong information nerd. If there is a book about something that intrigues me, I will probably buy it.

I would not expect this book to ever be digitized. The target market is small, which is also partly why it is so expensive.

I did a little looking around and found a used copy for $79. Here is the link:

https://www.morgancountyseeds.com/product/compendium-rose-diseases-pests-second-edition/

There is a third edition out now and it is around $175. Ouch. I think I'll stick with the one I have.

For snyone still following / I am sending soil samples and stem samples to Texas A&M. They have been helpful in past with RRD. Thanks again everyone. It will be interesting to see how close we got in analyizing. I will post update when I get it. probably 2-3 weeks they say.

I have read that one needs to remove ”all leaves with fungus or pests like the saw fly holes in leaves, then spray.”

I believe it is fungus….. a type such as Downy Mildew. I had something similar-lookedcalmost samecas yours-, removed effected leaves, sprayed a fungicide.

if it is slightly purple- black-it is Downy mildew.

It circles the edges of the leaves sometimes & travels on top of the leaves veins spreading.

You will know it is Downy Mildew if the top leaves of the rose bush are effected first. (Black spot happens to bottom leaves first & DM effects top leaves first.)

Your photo, see how the edges if the leaves are covered in it-it is on the edges of the leaf.

Downy Mildew comes in lighter & darker purple varieties to almost blackish purple. It can go around the edge of a leaf. it can soread over the veins of the leaf filling it in more daily. This is one variety of DM belo photos….

On some roses it is lighter purple & around leaf edges.

sometimes it looks more lighter purple & blotchy-almost a total different look.

DM looks different on other varieties of rose leafs.

Humid hot weather brings on fungus. I treat my roses for all types of fungus. I pretty much have had all of the above and many more types. I studied pest and fungus management for awhile and did some rose consulting.

These leaves have saw fly/rose slug holes. Effective pest management requires removing all infested leaves. Saw flies lay eggs on the leaves, they hatch and eat small holes in the leaves and eventually they eat the entire leaf almost and leave it appearing lacey veins only. To remove an infestation, remove all leaves with holes and spray, which is recommended by experts. in addition, once an insect has bit into a leaf, the leaf gives off an aroma which attracts that insect & it’s friends to locate the damaged-bitten leaf and munch some more. , Getting rid of the damaged leaves stops the insects from returning.

Also, wiggle lines on leaves can be leaf miners.. I see a couple wiggle lines. Insect treatments can eradicate the insects on the leaves, but remove all leaves with insect damage, also to better control it. .

I do not think you have manganese deficiency.

Plants now have Chili Thrips. Not surprising they were probly weakened. I am trying a new product calked XXpire. it is suppose to be the new one that works without causing harm. We shall see.

I have read all comments carefull and studied them in comparison to my problem. i have come to two conclusions. First this has got to be kindest, most caring, helpful group of people in any online web posting organization.

Second conclusion is that each comment has merits that point to it being the correct diagnosis.

I am going forward to first treat the darn chili thrips. I am hopeful XXpire will be as good as I read. Has snyone used it?
