I seem to be developing a problem with my pygmy gemmae. I have so far lost one D. Stellifolia and two D. Dicrhosepla to some kind of fungus. I am aware that gemmae need higher humidity in order to 'gemmanate' but now they have developed a few petioles each is it time to reduce the humidity? Why has it only attacked certain gemmae which are growing in close proximity alongside one another?
Will fungicide harm these youg plants?
