As others have said, it is normal to lose any growth buds on new bare-roots, so that's not a concern. The rose has to grow hair roots before it can take up enough moisture to support growth. This may take 3 or 4 weeks. It's a good idea to mound soil over the cane stubs or spray them with anti-transpirant to reduce moisture loss. 50% manure and alfalfa is too rich a mix. I don't know whether this will have bad consequences or not, but the danger is not heat so much as excessive nitrogen that can burn hair roots and foliage, or excessive salts that can inhibit water uptake.

"Propagation: Rosa Damascena is propagated through one year old stem cuttings. It can also be propagated through the divisions of old plant, lateral sprouts with roots and seeds. Stem cuttings are collected at the time of pruning in mid October to end of December; 20 cm long, 0.75-1.50 cm thick cuttings are planted in nursery; 2/3 of the stem length is inserted into soil. IB A @ 200-250 ppm is given to induce rooting. These cuttings are ready after one year for transplanting into main field." http://www.tandfonline.com/doi/pdf/10.2478/V10133-010-0032-4 ---------------------------------------------- " The cultivars and ecotype of Rosa damascena Mill. have been grown by using cutting or two old-suckers for many years" "Stem cuttings are collected at the time of pruning in mid October to end of December; 20 cm long, 0.75-1.50 cm thick cuttings are planted in nursery; 2/3 of the stem length is inserted into soil.

Thank you, Val, excellent info about the dose (2 Tablespoon) .. is your soil sandy/loamy ? Sandy soil leaches out salt easier than clay (retains salt very well). Seaweed from CA (alkaline clay) raises her own-chicken, she dilutes her fresh-poo with water 1st, before applying. Seaweed has 11 inch. of rain, compared to Newberry, Florida of 47.33 of rain. Sulfate of potash has salt-index of 43, at half of salt-index of high-nitrogen chicken manure. I put 1 teaspoon sulfate of potash per small own-root rose. The roses in loamy potting soil (MG-moisture control) .. didn't mind. But the roses in my dense & heavy & sticky clay wilted in hot sun, despite my watering in. For that reason I don't apply fertilizer in clay, unless it's all-night, or all-day rain right after application. When the deer ate all the leaves off my own-root Firefighter rose in June 2013, I spread 1/3 cup of dried-chicken manure NPK 5-3-2 around the bush .. and watered that in .. but we didn't get rain for over 2 weeks in June, and that burnt some of its roots, it didn't survive winter. The late rosarian Karl Bapst, zone 5a, also warned folks about less granular fertilizer in spring since the newly-grown feeder roots is so tiny, thus too much granular fertilizer will burn it. Zone 5a own-roots are so small, with winter below -20 killed all the feeder-roots, and new-growth is very tiny.
