    It depends on how dried out and dead the roses are. If there are still good green canes and some good foliage, then there is a chance. If the canes are all dried out and showing the signs of being withered and turning to brown, then perhaps not. My suggestion would be to water the rose garden well with some water that has Super Thrive added to it. If you cannot find the product Super Thrive where you are, look for it on Ebay or Amazon.com and order some in. Also obtain a good root stimulator product. Add both items to the water you water the rose garden with the next 4 to 5 times the garden needs watering. Prune out all the dead and withering cane material down to where good healthy material exists. Prior to one of the waterings, sprinkle 1/3 cup of Epsom Salts around each rosebush and scratch lightly into the soils. If this does not bring the rosebushes back, it is time to dig out all the old rosebushes and plants and replant it with some you always wanted to try. Or replant favorites and mix in some new ones.

    The first thing to do is to stop feeding and dead-heading the rose. Fertilizer and dead-heading give it the signal to grow; new growth at this point won't have time to harden before freezing temps. If you can, the best approach to winter for a container is to bury the rose, pot and all. Above ground, a container plant is considered less hardy. If your rose is listed as hardy to -29 C may only be hardy to 0 C above ground. This is because the entire rootball is likely to freeze solid; roots will not be able to replace moisture lost by canes in drying winter winds. This creates conditions for tip die-back which can be severe. Do you have a shed or garage; placing it there will at least reduce winds. If the pot will be on concrete/cement, place insulation between the pot and the hard surface. Surround the rose with chicken wire and pack with leaves, straw or blanket insulation. Cover the rose crown with 6 cm of soil. Once the soil is frozen, add additional dirt to cover the canes. It is not too late to plant a rose and it is the safest alternative.

    You can prune after flowering in early summer. They only bloom once and on old wood, so pruning any other time will cut off the next season's blooms.

    I don't see a rose disease for this either. It can be natural.

    Yes, rose seeds do need the stratification period to sprout and grow. Please keep in mind that some rose seeds available on-line at various websites are a scam. They are not rose seeds at all. Most will not ever sprout and are not any form of seed. Instead they are small clumps of organic material. Here is a link to my article on growing roses from see for you as well: https://www.gardeningknowhow.com/ornamental/flowers/roses/growing-roses-from-seed.htm

    Basically there are two ways, two different times of the year to grow roses from cuttings. Softwood Cutting Season begins in June and continues through the summer. By fall the wood hardens off and you have to do things a bit differently. https://fauxncotton.com/
