I recently received my parent's fuschia and, while it bloomed often and fully before, it no longer grows new buds and the existing ones are dying before they open. A few of the leaves are browning. It's September 1st and I live in a agricultural area in California.
The plant is in a warmer environment but gets much more shade as it's kept indoors. I did feed it strong NPK (20-20-20) fertilizer tea and it exploded in buds for awhile. I pinched some off so as not to overwhelm the plant. It's always wet and I water as needed. I put it by the window to get more fresh air after the last buds died off and it's getting more sun but showing no signs of improvement.
Did I do anything to hurt my plant or is this natural fall hibernation?
