Need good book on houseplants
I am looking for a good, extensive and serious english-language book on houseplants! Hope someone here might give me some advice on titles, authors etc.
I have no prolem finding good books about garden plants, but when it comes to houseplants its another matter. 90% of the books seems to be of the type "beginners guide to ...", "... for dummies" or "50 plants you cannot kill".
Well, I have no intention of killing my houseplants - what I need is precise advice on watering schemes, fertilizer use (also when the advice is: none), light, humidity and maybe some background on the climate where the plant belongs. Preferably also for more unusual indoor plants.
I am sure such books exist, only I cannot find them because any search on "amazon" drowns me in the begginer-type titles.
