30+ Year Old Angel Wing Begonia. Prune Or Not To Prune.

Question

Previously I left this begonia outside in indirect sunlight in Tennessee. Not enough light inside so took into basement with one window in winter. It dropped all leaves and I cut it back each winter to about 3-4 inches. It always came back in the summer full and tall. I have now moved to Kentucky in a house with a wonderful sun room. I never took it outside this summer because it was happy and thriving inside. I did transplant it to a little larger pot than the one it has been in probably over 10 years. It has never bloomed, wish it would. Seems like it’s getting a little lanky and I thought I should prune it back some. Recommendations? It typically is in front of a 6′ tall window but xmas tree is there right now.

Answer 1

It should bloom if it gets enough bright, indirect light, humidity, and the proper nutrition. If you aren't fertilizing, try that and see if it blooms. Choose a fertilizer a little higher in phosphorus than nitrogen. You can lightly prune anytime, which also will encourage blooming.
