Would I be able to get a master's in horticulture with a bachelor's in geography?

I’m a junior currently pursuing a B.S. in geography with a focus in GIS. I went into geography because I wasn’t sure what I wanted to do but I was always interested in different places and cultures so I thought it would be a good fit and I heard that knowing GIS could get me a good job. However, I now realize that I want to go into the wine industry. My school doesn’t offer a degree in horticulture and I don’t want to change majors because I’m too far in at this point. My school does offer a minor in ecological restoration from the forestry department so I think I’m going to go for that because you have to take classes in soils, water resources, ecology and other things that would be valuable for horticulture. Would this be a good idea and/or possible? If not is there any jobs in the wine industry that could use someone with a geography and GIS background?
