Rose bush problems!

It sounds like witches broom disease. It causes deformation on the canes, buds don't open and can cause an excess of thorns. If all of the rose bush is affected, there's nothing you can do to save it. There's no cure for witches broom. All you can do is try to prevent it. Horticultural oils or miticides.

some roses are grafted on to 'root stock' it may be that the root stalk part has taken over from the grafted canes. wild roses don't look like a traditional floral shop rose. the flowers may be pink or white, and usually only 1 row of petals.

the other thing to consider is....do your roses have a fungus/ parasite/ virus issue?

a master gardener can help you out.

I add chopped banana skins to my soil for my roses and the roses that grow are healthy and beautiful. Check for parasites also there are many all natural ways to use . google rose pests and you can probably get a lot of advice on this method.

The American Rose Society has a program enabling members of local societies to become accredited Consulting Rosarians. One of the things CRs will do is to come and visit your rose garden (for free) to look at your rose problems and advise you on how to deal with any diseases or pests your roses may have. Your closest rose society is the Detroit Rose Society (http://www.detroitrosesociety.org/Detroit_Rose_Society/Home.htmlv). I noticed that this page hadn't been updated recently, but once members become CRs, they tend to keep that accreditation updated as long as they are growing roses. Give them a call. Alternatively, look at their schedule and take a clipping to a local event. Someone there will be able to help you.
