Not intentionally, but one year I had a cherry tomato plant that had some fruit left on it by winter and a storm blew off the rest into my rose bed. The next year, I had a lot of volunteer tomato plants in the bed. Didn't see much difference in the roses. I would say to compost the tomatoes first to make sure they don't sprout (but even composters have the same problem with volunteers in the compost bin).

Those nutrients in the tomatoes probably would only be made available to the roses if you had sufficient levels of organic matter in the soil so the soil bacteria would make those nutrients available, and if that happened the soil nutrients would be enough in balance that the tomatoes probably would make little difference.
If there are insufficient levels of organic matter in your soil and little bacterial activity those nutrients may take so long to become available as to be next to usless this growing season.

On the other hand, if you make a tomato smoothie and add that to your compost pile, you eliminate the problem of the seeds sprouting in your rose beds, add the moisture and nutrients to your compost to speed the process. Can't hurt. Seamommy
