Agreed, depending on the climate, from my limited and mostly indoor cultivation of about a dozen species for around 12 years. A steep learning curve as I started with frost hardy cold temperate plants. The Stagnospora rots the roots at the basal plate, and the neck of the bulb, thus depriving it of both roots and leaves. Then any new leaf emerges with black tips and red margins, the outer scales of the bulb then die and rot........ given careful cultivation, minor infections disappear in a year or less, without chemicals.
