Hi! New here, from Central. Florida. Just planted 28 roses over a series of two mos, and getting very frustrated b/c I can't figure out what's wrong with a few of my roses. I know I made a mistake and overfertilized w/Bayer systemic, b/c I can't add and didn't use enough water! However, the roses seem to have adjusted after dropping some leaves, and seem healthy.
Biggest prob I have is w/Ebb Tide, a floribunda, and Granada, a HT. Esp Ebb Tide... Both were bushy and beautiful, but now leaves all over plant are turning orangey and dull, and will drop off easily if pulled. Same w/Granda to lesser degree. Doesn't seem to be affecting blooming, but don't want to lose all my leaves!!! Hubby was watering with sprinkler right before dark, but have put an end to that. Both have plenty of sun, good soil and drainage. Other roses next to these don't seem to be having probs, and these two roses have one rose between them that is doing great. All my roses are planted at least three feet apart, so aren't being crowded, and have good air circulation.
Any advice? Many, many thanks--these roses are a huge investment for me, but also one of my biggest sources of joy and stress relief!

Take a piece of white paper out into the garden and tap the leaves with it under them. It's early for spider mites, but you never know. If you get little black specks, it's spider mites. There are a number of products on the market for spider mites, you chose what you're comfortable with. Make sure you spray all of the roses though so they don't just move to another rose. Spider mites hate water. If you spray the underside of the plants with water at time of day when they will dry before night, that will help keep them at bay.
Downey mildew is also a suspect. You want a product with captan in it to control downey. http://ohioline.osu.edu/hyg-fact/3000/3013.html It's not well known on roses, but it does happen. I had a problem with it a couple of years ago. Again spray all of the roses.
The south, Florida in particular, has problems with nematodes. I have absolutely no experience with this problem. You'd want to get in contact with your local Rose Society or Extention office to determine if this is the trouble.
Best of luck

This is good advice, but I have found that I can control spider mite infestations with washing the plant several days in a row. This breaks the breeding cycle. After the infestation is under control, just washing the plants when I water seems to be sufficient.

Thanks so much, both Wendy and Lyn. I sprayed w/a mixture of water, baking soda and Ivory dishwashing liquid that I read about on the site. So far, no response, but we'll see... If not, I'm going to try one or both of your remedies. I notice that the roses themselves also appeear washed out, color-wise, and the new growth appears somewhat discolored/distorted. It's driving me nuts, since I've never seen something like this before!!! I used to grow roses in Dallas, and have had just about every kind of problem... (Seems like every new rose I plant gets some yellow leaves, which I guess is it adjusting to transplanting. However, I always seem to get blackspot, no mater what, even though I water via soakers, and have taped up any holes that sprung and were spraying the roses from below... I think it's all the dew on the roses that forms overnight here in FL...)
Many, many thanks--smiles to both of you and your gardens!!!

You need to break the breeding cycle of spider mites to regain control of the impact of the infestation. The only way I know beyond using major chemicals is to wash the plant daily for several days in a row. The fact that you are watering with soakers leads me to believe that washing undersides of the leaves will be an important maintenace task in your garden. They go hand-in-hand.
However, that may be only one of the problems you are experiencing. Wendy's mention of the nematode problems in Florida soil is something you really need to learn about. So far, I have heard about this from many people growing roses in Florida. I do know that rose fields in Texas were treated with tilling in pine bark to fight the root nematode problem there and, from what I have read, it worked. I don't have that problem here in my garden, so I cannot even begin to give you good information. As Wendy suggested, it's best to contact local sources for information about this issue.
Good luck with your roses.
Smiles, Lyn

Thanks so much, Wendy and Lyn! Yes, I'm sure it's spider mites, since I used the paper and saw some small ones and bigger ones. Also, I have small webs every morning. I have sprayed with a mixture of water, baking soda and dishwashing liquid, and the yellowing leaves have diminished somewhat. I keep pulling off the rusty yellow leaves and putting them in the trash, and am getting lots of new growth and flowers. So, I'll keep it up. Lyn, when you say wash the leaves, what do you use?
I have soakers in the back, but in the front, I occasionally use sprinklers for a good soaking, making sure the leaves have enough time to dry, or else use deep watering via hose at the roots, making sure not to get the leaves. It's strange that three of the six roses in front seem to be having the probs, but the other three are fine. Two are floribundas, and one HT. Ebb Tide got it the worst and last, and Granada the worst first and Shocking Blue somewhat. My Knock Outs are fine, of course. Of course, I always seem to get blackspot, and spray accordingly. Is there a cheap way to combat this via homemade solution?
Doing some research, I've found that when it's hot and dry, spider mites love it. We've had very little rain... I researched nematodes, but luckily, doesn't seem to be the case. I purchased plants w/Fortuniata rootstock, which is esp for preventing nematodes. Thanks again, so much!

I'm glad it was spider mites and not something else. They're a pain, but managable. If you blast the under sides of your leaves with water, as Lyn suggested, for several days in a row and then do so a couple times a week you should be able to keep the mites in check.
I've heard that corn meal spread around the roses works well for black spot control. In FL the humidity makes that a constant battle as well, so I wouldn't take as something you are doing wrong. Regards Wendy

What do I use ? A very strong spray of plain water. If you wash them off, they don't breed. I know it sounds simplistic, but it has always worked in my garden as long as I washed them several days in a row. Then I washed them once or twice a week throughout the season and never had a serious infestation. That's my experience in my garden.
As you can see from Wendy's post, we seem to approach spider mite infestations the same way.
You are doing a lot of things right. Healthy plants are less susceptible to disease and insect damage.
Smiles, Lyn

I just thought I would share my experiences with spider mites. I only get them with the few roses I have that are watered with soaker hoses. Most of my roses are watered overhead with an automatic sprinkler system and dont get them. The reason I think, is that the overhead water is blasting under the leaves too and keeping them under control. I do realize that conventional wisdom says "Never overhead water roses or that will give them fungal disease" but honestly I have been doing this for 8 years and I only get a little powdery mildew on them in the fall, after I have stopped irrigation. I have over 60 rosebushes and they are healthy except for aphids in the spring.

Thanks, Tabris! It's funny, I have some roses on soakers, but the ones that got the mites aren't b/c I'd have to run a hose across my walkway to make it work. . Sound like you know what works for your roses, esp if you have 60 and have been doing that for 8 yrs! I still have so much to learn...
The spider mite prone roses are now doing much better after I cut them back severly. I am continuing to keep an eye open.... I still think it's the hot weather/no rain that we've been having here in Central FL. We've recently started to get some rain, so that, combined w/previous spraying, seemed to work. Now, of course, we have the wonderful problem of black spot, but that seems to be primarily w/a few roses, Disneyland is the absolute worst... If I look at it, it gets black spot. I just keep pulling off the diseased leaves and spraying occasionally.
THANKS to everyone that has helped me out with my original questions! I guess we all love tending to our beauties, although I have to say some are more my faves than others. Tuscan Sun is my absolute love--no problems, and bushy and sprouting new leaves from the botton. Just wish it had more scent...
Anyone else have an absolute favorite rose?

I live in the Seattle area and I started a rose garden 2 summers ago. I want the most disease resistant roses I can find, so I won't have to spray. Last summer I planted Sunsprite, About Face, Intrigue, Lady of Guadalupe, Elle, Scentimental, Honey Perfume, Rainbow Sorbet, Double Knock Out and Pink Knock Out, and so far they are all very healthy and haven't got even a tiny bit of blackspot or anything on them. I have never sprayed them either and do not intend to spray this summer. I also have Marmalade Skies, Sixteen Candles and Salsa which all have a bit of blackspot, but not too bad. Does anyone know of other very disease resistant roses for the Seattle area which are fragrant and will bloom all summer?

Well I am not sure of your zone or conditions, but I recommend Distant Drums, Lady of the Mist, Quietness. Tropical Fragrance, Ingrid and Glowing Amber. And new for me Golden Buddha is also turning out Disease resitant and fragrant. Another new one that fits what you are looking for is Jeri Jennings. Check the HMF search fr this and the Buy from tab should tell where these can be obtained from. Good Luck

I'm very impressed with Fabulous, It's a floribunda, I think...Put out by Jackson and Perkins. The only thing is, it is getting taller and taller and I've trimmed it very short this year. I was so impressed with it, that I now have two. The blooms are white and pale yellow. From a distance you are mostly seeing white. I also love all my David Austin Roses. But I'm still wishing for a 'Morning Has Broken' rosebush put out by Heirloom roses. My problem with getting one from them, is that they come in a very small 6 inch plant and we are going on a trip in June...also we have an over population of deer out here in Granbury,Texas...I have to rely on my "Scarecrow" water system to keep them away. This has been the only thing that has worked for us so far, and I have 70 rosebushes so far......Phyllis

I live in Lynnwood, WA. I have an own root tuscan sun (floribunda) in a container for about a year. It is very disease resistant, no black spot or mildew. It survived this past winter storm. It shows healthy growth.

Hi! I live in Central Florida, which is quite a diff climate than Seattle. I am using almost all Fortunianata rootstock from Nelson's and J & P, which does well in FL. All of the roses mentioned below can be purchased locally in your area, I imagine. Have planted over 28 roses this spring, and already had two HT own root roses that came with the house--Fragrant Cloud and Sterling Silver--hubby ran over this one w/his lawnmower, and it came back! Both have gorgeious smelly blooms, but are prone to blackspot. Take my advice with a grain of salt, b/c these are new plantings, but so far, I love these roses--vy little probs, and few issues w/black spot after I told my husband not to water right before dark. I have most of these roses on soaker hoses, as well. I agree, Tuscan Sun is a beaut. I've had it planted for almost two mos, and it thrives--multicolored blooms of yellow/orange/pink that change color as the blooms age, very bushy, loads of new growth, blooms from the botton, and nice, mild spicy scent. Also, have had really good luck with Shocking Blue--it's a deep lilac purple Floribunda, Celebrity, a huge flowered yellow HT with edges of petals trimmed in pink on young blooms, and Madame Isaac Pere, a deep pink Bourbon and bushy profuse bloomer. (All three of these smell WONDERFUL.) Also, I love Burgundy Iceberg, a vigorous deep purple Floribunda with a light rasberry scent. Love & Peace, a pink and yellow HT is gorgeious, very disease resitant, but only has a vy mild scent. If you like climbers, I brought Golden Showers back from an ugly looking plant I bought at 1/2 price--milder licorice smell, but beautiful yellow blooms, glossy leaves and very vigorous. Good luck--I'm new here, and this site has been great.

Thank you so much everyone for responding back. I'm going to check out suggestions made by all of you. We dug up half our front lawn 2 summers ago and made it into a rose garden. I have a black-gated arbor at the entrance to it and a small waterfall to the back with a statue of the Blessed Mother over it. I can't believe how much work it has taken to put this rose garden in. My Seattle dirt was solid clay and my husband couldn't hardly get a pick or shovel through it. So he spent the end of summer '05 and all last summer '06 digging up all the clay dirt, hauling it off in buckets and then bringing in good dirt. My rose garden is a rectangle with 6 foot wide beds all around for 30 roses. He also put in a soaker hose and hooked it up to our sprinkler system. This year we thought it would be easy because all the digging was done but actually finding the right roses has been harder than I thought. I would rather put some extra thought to the roses now though, instead of having to stress out over them after they are planted because of disease.
Phyl, how do you keep the deer from eating your roses? My sister lives in Woodinville, WA and she has lots of deer. She's quite the gardener but decided to give up on roses this year because the deer keep eating them up. And as far as buying the "Morning has Broken" rose....I just bought "Velvet Fragrance" from Heirloom, it is tiny but I'm going to plant it in a pot and let it get bigger before I put it in the rose garden. Maybe you could do that too and put it somewhere the deer can't get to it. Then when you get back from your trip in June you can plant it out in your garden. I did that last year with "Antique", a climbing rose from Heirloom and since it was so little in my garden I put a tomato cage around it to protect it. The Heirloom roses do grow fast though, so you won't have to wait long for it to grow bigger.
Again, thanks everyone, I'm new here too and it's great to be able share tips.

Hello...Your garden sounds great! We are basically doing the same thing..taking out the old dirt and bringing in the good dirt. In reply to your question about the deer...I bought the "Scarecrow", that was on the internet..You should be able to click on the word, scarecrow and bring it up...The scarecrow is plastic and looks like a black bird. It has a battery inside and is heat sensored. It's hooked up to the waterhose. Therefore, when anything comes within a certain distance..it squirts out water and then stops...it that something doesn't leave, it squirts them again with water. So far this has worked...and it shoots water out approximately 30 feet, depending on the size of the scarecrow. It revolves from one side to the other. Some do farther, but I didn't want to invest too much in something that I wasn't sure about....and another thing....the grandkids just love this...they enjoy watching it squirt their granddad..
I have really tuned into what is disease resistant and what isn't..I know that Dolly Parton is my worst rosebush for blackspot, but she has the most beautiful roses of all...That's the only reason I've put up with her all these years...A great one to buy is called Honey Perfume....The only problem with this one, is beetles....If there is a beetle a mile away, this rosebush attracts it....It's yellow, which they seem to love and it's very perfumed like honey....But ooooh how pretty it is...So tell your sister about the scarecrow. Maybe I will get 'Morning has Broken" afterall...Thanks, Phyllis

Hi, I live in the Seattle area and I suggest rosa rugosa roses. They are the easiest of all of my roses. I do not spray or fertilize. They are blooming now, producing many "starters", will bloom all summer and blackspot resistant. They will grow and spread forming a hedge in almost any soil including sand. I have pink but there is also an alba rosa rugosa. They are very fragrant. They are not a good cutting rose but if you want easy go with this rugosa or any of the other rugosas. You might check out The Uncommon Rose. I just recieved in April a Linda Campbell (red) and a Green Ice from them and both are already blooming with no care. I have picked up many small rugosas at Church sales area so you might look there too for inexpensive roses. Good Luck with your roses. Jody
