Ah what lengths I will go through to fit more dahlias. I did some research on most efficient circle packing in a unit square - why? Because the plants would occupy a roughly circular area, so you could use circle packing to get the most efficient use of space. So I want to expand my large section into one giant bed 20' x 40', effectively two squares. Using the info on a circle packing page, I could pack 140 30 inch circles into that area, with five rows of 16 and 4 interlocked rows of 15. A nice hexagonal packing, the most efficient possible.
