What is an acceptable mortality rate in collections?
I read recently in another thread that orchids are, in theory anyway, eternal, so I guess everybody's rate should be 0%. I know in practice, however, that is not the case, so I wondered if anyone could help me make some honest comparison. I have about 300 plants in my collection and I guess I lose on average about 20 a year, which is about 7%. I make up the number with purchases and propagations/swaps etc so the number is stable.I think this figure is too high though and I do what I can to reduce it by cutting out the crass negligence etc. I also bin a good number because I don't like tending failing plants, which pushes the figure up, but I reckon you have to do that. What are other folks achieving?
