I think oreos do require wetness early on in the season in order to hold on to their new pitchers, and at this time in Alabama it is wet after winter and spring rains.
What time of year were the soils bone dry? During summer the old pitchers are lost because of the dryness, and this even happens if kept soaking.
I keep my oreophilas wet as I do all my others, and they lose their pitchers in July. I find that keeping them wet though you can gain a small second crop in summer, albeit just a couple more pitchers.
