How to Propagate Begonia Seeds

Begonias can add a splash of bright colors to your outdoor landscape or potted container garden. They're also relatively easy to care for. Instead of buying mature begonias, you can germinate seeds. To get plants ready to bloom by summer, sow the seeds in December or January.

Seed tray
Sterile, soilless seed starting mix
Spray bottle
Begonia seeds
Plastic kitchen wrap

Instructions

- 1
  Fill a shallow seed tray with sterile, soilless seed starting mix. Fill the tray to within 1/2 inch of the top.
- 2
  Sprinkle the tray with water so it's evenly moist--to avoid disturbing the soilless mix, you may wish to use a spray bottle--or, if the tray has drainage holes on the bottom, place it in another tray full of water. The tray-within-a-tray setup is ideal for preventing overwatering and reducing the development of fungus.
- 3
  Press one or two seeds a couple millimeters into the surface of the soilless seed mix, spaced apart by a couple inches.
- 4
  Cover the top of the seed tray with plastic kitchen wrap and place the tray in an area that receives indirect light. Maintain a temperature of approximately 65 to 70 degrees Fahrenheit.
- 5
  Remove the plastic wrap once the sprouts have broken the surface. This usually takes about seven days.
- 6
  Mist the tray once a day with water.
