Are rhizomes supposed to be buried under the ground or sit on top of the soil? Last year I noticed that my sarr rhizomes appeared very prone to rot buried as they were in the soil. When I dug some up to divide them I saw that roots had been growing out all over the place, even from the top of the rhizome. I thought this could not be good for pitcher development and may choke out the plant, so I potted many of my sarr rhizomes a little bit above the surface this year. However, a couple have not resumed growth yet and may have dried out. I had originally chalked this up to division stress but now I'm not too sure. I can take pictures if it would help. Thanks!
