Man, I hate hearing about losses from rot. I've been fortunate to be rot free; the mix I use is 50:50 peat and silica sand, with a small amount of high quality lfs at the container bottoms so the media doesn't leak out. I go to a construction supply store and ask for 'sandblasting sand.' Like others have said, be very careful not to breath the dust as it will turn your lungs into sushi.
I grow my Sarracenias in a grow tray, filling it up to at least 1/4 pot height then let all of the water get used up till the tray is bone dry. This helps keep mosquitos from breeding (plus I use mosquito dunks) and also hopefully helps with root aeration. I only let the tray stay dry for 24 hours at the most during growing season so they don't get stressed. In the winter I store them in my unheated garage and let the trays go dry for longer periods of time.
I'm currently having rot issues. Been growing 4 yrs and this is a first for me. I have about 10 out of 50 plants affected. It started with a dewthread tho. It was coming out of dormancy and the outer layers of the hibernacula were turning black.
One grow site vid recommended water no more than halfway up the pots but after reading this thread i reduced the level to just above the drain holes and will let that go down before adding more. I'm hesitant to top water since I lost one after doing so. Lost another when I did a repot during the grow season.
I'd like to repot everything now bu I'm worried obout losing anything else so I'm going wait until early spring 2021 with perlite in the bottom of the pot with the screens over the holes. I liked that idea. Was thinking of doing that before I read this thread but this just solidified it for me. Only thing extra I might do is add a plug of lfs in the perlite that reaches into the soil mix so it can get water. Thoughts?
I've also used the propiconozale but, for a few plants, it was too late. My r.rose looks like it'll pull thru and my maxima is still iffy. Anyone know what concentration to use? I did an 8 oz per 100 gal mix and let the entire pot sit up to the grow point for about an hour. Anyone know if it should be a higher concentration?
Lastly, from what I've read, I like the idea of using sand in the soil mix. Pool filter sand? Sounds like a good price for quantity but, does it leach any hardness into the water? Love the idea of glass silica but, yes, its expensive.

adaetz100: Sarracenia purpurea tends to add a lot of red/purple to its offspring, but there are some lovely dark red flava x leucophylla crosses too. Look up 'Royal Ruby' if you're not familiar with it already--it's a natural flava x leuco hybrid
