Evan, the water that it's in is very small. Probably what would have helped it was the tree canopy overhead. But the length of time it stays cold probably has a big bearing on it as well. If it's cold long enough for the chill to get into the plant tissue there possibly could be damage. Last year was a mild winter. Normally July would have had those June temperatures one or two days also. This winter looks like being more normal, in that temperatures will probably bottom out a few more times. Already had a 15.8C although technically were not in winter yet.
