Hi, first time growing dahlias. Im in central Florida, so my dahlia is already starting to sprout. It has 3 shoots coming up from the tuber. Am I supposed to leave all 3? Or should I leave only 1? Im not looking for show winning blooms, but I would like a decent size and number for cutting. All the tutorials either don't say anything about the number of shoots, or seem to imply that there will only be 1. Any thoughts would be very much appreciated.
