Leaf drop on Begonia maculata
What causes sudden leaf drop of young, glossy green leaves on an Angel Wing begonia? An otherwise thriving 6 month old cutting. There's no infestation, the stems are healthy, there's nothing wrong at the bases of the leaves - just a damp little bit that eventually dries off. Utterly bizarre! It's got good light; a large pot; stick-it-in-and-leave-it-BabyBio droppers. Could a new leaflet push out one already established? All the dropped ones, so far, have had tiny leaf spikes sitting directly behind them at the base. I hate hearing that 'floppp', turning around to look knowing another one's gone. Help, before he goes completely bald! Thank you in advance.
