So how is it that water plants like lilies, Cattails, and rushes are green and full of chlorophyll? They uptake calcium just fine in solid water. Of course too much rain will waterlog the soil and damage roots. But I'm not buying that Banana soil with the right amount of constant moisture needs to dry out. Waterlogged and just moist (constantly) with sufficient air in the soil are two very different environments for roots. I'm convinced that there's no need to dry out if the moisture conditions are ideal.
