When Do Begonias Stop Flowering?

Begonias offer a wide array of colors, sizes and shapes, making them versatile plants for home gardens, according to the National Gardening Association. Begonias exist as both annuals and perennials, both of which are long-blooming plants.

Time Frame

• Begonias planted outdoors bloom until a hard freeze kills the foliage. Indoor plants bloom continually when properly maintained.
  

  Cultural Requirements

• Begonias stop blooming if they have inadequate growing requirements. Outdoors, they need a partially shaded location for best results. Indoors, they need a brightly lit room. Begonias that stop blooming while inside usually begin blooming again when exposed to increased light levels.
  

  Tip

• Dig up tuberous begonias after foliage is killed by frost. Leave tubers until they are dry and then store them for winter in containers or peat moss at 35 to 41 degrees Fahrenheit.
