I'm still losing some of my smaller Sarracenias due to rhizome rot/melt/fungus/something. This summer has been unbearably hot and dry. At the past advice of one of our veteran Sarracenia growers--Bugweed--I've started growing my plants in undrained plastic tubs. About 2 years ago, I remember him explaining the nuances of why undrained containers or circulating bogs work better than the widely accepted tray method (which I've always used). He advised that keeping the rhizomes constantly wet ("the wetter, the better") and allowing the water to evaporate creates a healthier oxygenated environment than plants that rely on soaking up water from a tray. I decided to give this method a shot this spring when I found out many of my smaller plants were rotting away from their rhizomes. Yet, I am still losing smaller plants--why??
At this point, I am wondering if the sudden shriveling of many of my pitcher plants is actually due to unseen insect attack, rather than weather, water, or media issues. I've applied Orthenex to these pitchers and hoping this might repair the problem.
