When you talk about rhizome rot, is that more of a winter or a summer problem for you?
Another Florida grower here: I usually have problems with rot in the summer due to the excessive rains + tray.
Right now I'm switching over from tray growing to big community pots. I just have too much trouble with Sarracenia when I let them sit in water.
Watering depends on the time of year. All of our pots have drainage holes. During dormancy, typically we water once or twice a week, depending on how much rain we get and relative humidity. Winter/spring is our dry season. As Jeremy indicated, most rot problems rear their ugly head in summer when humidity is high and rain is frequent, but rot may occur at any time. Michelle does a mid morning walk thru nearly every day, looking for potential problems. It is important to catch rot problems early on before it spreads through the whole plant.
In spring, when temps are moderate, we are in the peak of our dry season, and the plants are just out of dormancy. Watering is daily.
Our plants get either rain or RO water.
We do not place sphagnum in/on our Sarracenia pots. We know it looks nice, but it is a major contributor to rot. Best to keep the rhizome as exposed to light and air as possible.Overall, it is important to avoid stagnant conditions.
Hope this is helpful.
The Fusarium fungus is one known cause of rhizome rot. Fungus gnats are a vector in spreading this fungus. By keeping your media on the dry side you are keeping the fungus gnat population at bay. What happens if you put a mulch of sand (~1/2 inch) on top of your pots? This keeps the gnats out since they need wet decaying organic matter for their larvae.
Grand Hotel... always the same. People come, people go. Nothing ever happens.
Thanks for your tips, Trent.
