Question
I received a rosebush last year and did not want to put it in the grown next to another rosebush that is fighting disease.I planted it in a large pot and it did very well. When winter approached I put it in the greenhouse, kept the temp at 60 degrees, and occasionally add some water when the leaves droop. I was amazed that I got a beautiful and fragrant flower! Is the plant in a dormant stage right now , or is there something I need to do before I put it back outside this spring?

Answer
In all depends where you garden as to when you put a rose outside. Because your rose is used to 60', the outside temperature must not go very far below that or the plant will be damaged or even die. If possible you will need to perhaps turn the heat off in the greenhouse if there are no other plants in there. That way the rose gets hardened off and will not mind being planted  where it will be colder. If you can't turn the heat off , then start by placing the rose in an unheated garage at night and outside in a sheltered area during the day. Again when the weather warms up and there is no chance of a nasty frost at night, plant the rose in your garden.
