Garden location 2 gets about half the sunlight than location 1 (3h vs. 6h).
I am skeptical that would be a reason for enhanced scaping. But, the combination of less light + GA may have some effect, perhaps.
I did not mention that my in-ground GA-treated seedlings are also scaping (I justnow noticed). But, there I was more random in the planting and spraying so excluded those as my notes are not as meticulous (as the varying environments would be harder to compare between seedlings, so I did not think it worth keeping great notes on those).
I have no more room to expand the testing. But, it may be possible to do so over time (yearly). Or, we can gather some interested folks here to try this next year and then do a meta-analysis of collated results.
