Depending how warm the weather is, down here I found it nearly impossible to over-water my E-ears. As yours, they were in nice, big well-draining pots and unless it rained, I was watering them 2 gallons, twice a day when the weather was in the 90's. You probably will get hotter weather than we do for at least some of the summer.
This summer, I have given most of them away, and something else is in the big pots, so the remaining EEars are all in one pot, sitting under a downspout. It has been raining cats and dogs almost every day for the last two weeks, so they're getting drowned, and loving it!
