Begonias In Hanging Baskets

Question

I take my baskets in each winter and start them off in a greenhouse in spring. They have bloomed profusely every year for last 5 years but having put on lots of vibrant foliage this year there is no sign of flowers? What seems to be the likely problem thanks

Answer 1

Generally lots of foliage and no flowers means the plant received too much nitrogen fertilizer. Try giving your plants a bloom booster fertilizer and see if that helps. Begonias don't usually need much fertilizer, but since yours are 5 years old, they may be spent.

Too little light can also be the culprit but begonias should bloom in part sun or shade. If they are in full sun, move them to a shadier location. Here is more on its care:
