I know that in the wild S. psittacina has been known to capture aquatic prey during flooding. Does anyone know how long can they be submerged for, or if it would begin to rot or kill the plant due to flooding being a temporary thing? Would it be a possible way to help curb the "wigglers" (mosquito larvae) in my outdoor watering trays? Would a submerged plant grow differently than a terrestrial one?
Any comment or discussion is welcomed and appreciated.

Based on wild observations and some of the more sophisticated cultured setups that i have seen, if you can keep the water moving they can be immersed for days if not weeks. The key, IMO, is keeping the roots oxygenated. When you have still, warm water on top of peat/sand substrate, conditions become anoxic very quickly.
Plants that i have seen floating in slightly moving water seem to be the most vigorous - possibly a consequence of well oxygenated roots and plentiful captured prey. Other things to keep in mind is nutrient exclusion in the soils - not just for the Sarracenia, but also for pathogenic and non-pathogenic fungi that likely play a role in the natural history (and culture) of these plants. there is still a lot to learn.

Agreed, Plus keep in mind in nature you are likely usually talking about a much large water column. It would be worth your time to read up on Hydroponics. Even if you have no intention to grow CP hydroponically (Which I have experimented with by the way with interesting results- I have also grown a good handful of non-CPs using hydroponics with some interesting results.), the basic principle behind it can tell you alot about where things go wrong with overwatering. Fundamentally, hydroponics is a way of flooding your plants without totally nuking the root system (and here is where the hydrogrowers come out of the woodworks to burn me at the stake). Yeah, I am oversimplifying with that statement, but the spirit is correct... |

Oh, try adding a bubble stone to the water, You might be surprised by the result  |
