Begonia, Richardsiana help
I purchased a baby, 4-5", Richardsina 8-9 yrs ago..as soon as roots filled its 2" pot 'it was shipped in,' I potted in a bonsai container. It grew like a weed, and flowered from spring well into fall yearly.
It's pruned a couple times a year, mainly to keep from growing every-which-way, given away many cuttings, 'since I prefer not to discard healthy growth.'
I don't know if I pruned too early, but after its haircut, it stopped growing, totally! Instead of new growth, leaves are dropping. It's evergreen not decidious.
Could I have killed it by pruning too early? Or is it something entirely different? It gets fertilizer and Superthrive during growing season.. Since it's on the ledge of a kitchen window, I hose foliage once or twice a week, without wetting soil. Any ideas? Thanks, Toni
