One factor to consider is how fast the fertilizer breaks down into a form that the plant roots can make use of. One thing about "organic" fertilizers is that they must first break down via soil bacteria, fungus, earthworms...so timing would be effective if you knew how fast the nutrients make their conversion--or if you used an instantly available chemical fertilizer--maybe foliage feed--if you believe in foliar feeding...
A study done by the UC agricultural division found that roses have their maximum need for nutrients when they are in full bloom. This study was done in greenhouse conditions with the roses in a hydroponic solution. The amount of fertilizer absorption was precisely measured by seeing how much fertilizer was removed from the hydroponic solution by the plant roots, allowing for degradation, evaporation, ect. So giving roses a quick acting fertilizer at full bloom might give you maximum results.
However, simply providing moderate, steady amounts of nutrients in the form of compost and regularly applied organic fertilizers will likely do just as well. Experiment and see what works for you.

Oh how I love the enthusiam, photos, and sharing on this thread! Thanks all!!! I love lavender roses with a passion. So far my experience has been that I can grow them beautifully, no spray in my semi-arid garden. You've started off my morning on such a happy note! Thanks again. :-)

Hi, Advice appreciated. Trying to select new coral/orange rose for 60 foot planter.I have had great success with landscape rose called Drift in coral in my succulent garden.
they bloom continuously need no care but are not what I want for new planter. Currently have Ficus Repens and Hydrangea in the planter but it is just too sunny for hydrangea.They get leaf burn and I need to move them back to other side of the house where they did well. Roses I am considering are Coral Beauty,Carefree Celebration,Matchless Mother, Grand-Duc Henri, Tintinara, and Memories. I really love a larger blousey type of blooms and the landscape roses are great at a distance but small blooms.The planter is deep and 24 " wide and not enclosed on the bottom for good drainage.I want to be able to cut blooms for the house. Sun & water are no problem but choosing ten of the right roses is the challenge. All advice appreciated.Ficus is out of control as I am trying to espalier it and supports not all in yet.



The Tulsa Rose garden, at one time one of the largest in the United States, has revised it's RRV fatality list from 1/2 of the roses infected last fall to 2/3 of the roses infected with this years new burst of spring growth. Even more roses (100%?) may be infected and eliminated from the garden. They will not replant display roses until some sort of viable solution is found. Until then it will be planted with other ornamentals. They have plans to be a test garden for resistant RRV roses, but I don't know if they will follow through with that. Ironically the initial large breakout of RRV started in a long hedge of Knockout roses. They have had small outbreaks off and on for years, and I remember confirming my first case of RRV back in 1988 with the park horticulturalist. Last year I lost more roses then usual myself. Currently I do not have plans to replace them either. The mites are carried on the wind, and if there is anything Oklahoma has in abundance it's wind. Sad to see over 3,000 roses destroyed at this once beautiful park by this disease..........Maryl

Hmmm....that's interesting! We don't have an attic in our garage - but I imagine you could just have it lift them up to whatever height you want - for example onto a shelf. I'm going to show this to my husband. Thank you so much for thinking of me!! :)
As to the grafts - I did at first - but now I don't, and there's no need. Our garage is insulated and we cover with a lot of blankets. Right now there's snow outside - but I've taken off the the blankets from the roses. The canes are such a lovely green color. They are so pretty to me - just the canes alone. :)
Hope your garage lift goes well - and I'll tell my hubby. Thanks!!

I don't really have a loft, it's more a four foot high area over part of the garage. Good thing I am short, but what's a little aching back for more roses. I was just admiring my lovely green canes this past weekend. Did you ever take the temp in your garage this past winter? Mine is insulated on two sides so I think it should work. After looking at your picture of Queen of Sweden I had to have one. Thanks for posting it.



If you can bend one of the canes so that that part of the cane can buried for several inches, it wiil form roots at that point. See:

I used various hardy low-growing genarniums (e.g, Geranium Rozanne) and ceroposes (e.g., Mercury Rising) and lots and losts of laveders to fill in the empty spot between my roses. It has worked well for me so far (about two years) as none of these appears to an agressive competitor to the roses. (The bonus point is that they are supposed to be "deer proof"/"deer resistant" although "my" deer seem to eat anyting and everything when hungry....) I have a very small gardening space (thanks to the roaming deer) so I try to fit in as many plants as possible in my fenced front yard. I dislike mulch as space fillers, but my ideal garden could be a weedy eyesore for those more organized.. This year, I am adding chives among the roses, which is supposed to repell pests.

Let us know Susan how it works for you. Good luck!!
Oh too bad redwolf. Maybe you could play paint with the white stuff. Paint a happy face on your hand. Make it "talk" etc. Then paint one on her hand. Don't make any notice of the splinter. In fact do a face on each of your hands and each of hers (starting with the nonsplintered hand). You could maybe even put in some food coloring in it so that it doesn't look white - then maybe she won't connect it with the first white stuff. Hope you can get it out this way for her. :)
Redribbons - yes make sure you have baking soda for the thorns.
Seil - it's STILL snowing. :(

Just snap or rub them off with your fingers. The plants will grow new shoots, no problem. There is a good reason to remove them. They are using carbohydrates stored in the canes rather than getting their nutrients from the root system and sunlight (because the root system isn't doing anything right now), so they are stressing the canes a bit.

Is this a climber, handg? If so, could it be Crimson Glory, Climbing?

Great use of color and the background tree (Eucalyptus ?) adds to the whole compostion.
Thank you, iris gal. Can't take credit for that, though. Just putting in my roses where they'll fit. I do love the JJ and cm colors together.
Hope pic isn't upside down. I google for info,, and seems this is an ongoing problem without a fix. ;(
