If there is too little nutrient in the substrate they sometimes shed their roots as a way of moving around and propagating the species. Low light can also cause them to want to float to the surface. From a nutrition perspective: - some micronutrient deficiencies will cause the stems and roots to be more susceptible to rotting. Boron is one candidate I think. If your micronutrient ferts have Boron, I would try a solid fertilizer in the substrate near these plants, or even just mixing some laterite in with your substrate in that area. Good luck |
