josieskid,
Do I ever have standing water? It is very seldom I don't have standing water. The first year growing many plants in the bog I felt sure they were doomed when the freezing weather came (the bog was much wetter then than now due to all the organic materials I have hauled in). They took it in stride and showed no signs of adverse effects. Now I know our winters (this one doesn't count being we didn't really have one) are not that harsh. But I have had a few winters now that really did get down in the low teens. Not saying that the entire bog bed is constantly submerged in water, but there are large portions of it that it is normal to have standing water. Have I ever lost any plants down in the bog? Yes I have, but I blamed that more on dormancy issues than rot, but it could have been the result of rot, there was just nothing left when I tried to dig in the spot where the plants had been. But, only a very few, three or four out of well over a hundred plants.
