The Fire begonia (Begonia tuberhybrida Nonstop Fire) is a variety of heat-tolerant begonia that will set a shady corner of the garden ablaze with double blooms in orange, yellow and red. Flowering from late spring into early summer, the Fire begonia grows to 10 inches in height and 12 inches wide with solid green foliage. In hanging baskets, patio pots or in a flower bed, the Fire begonia will thrive as long as it is in shade and kept moist. Sow the Fire begonia seeds from mid-January to mid-March.
Fill the seeding tray with seed-starting mix and water it until it is completely saturated. Allow the tray to drain completely.
Hold the seed packet over a sheet of white paper when opening. The seeds are extremely small.
Scatter the seeds over the surface of the soil in the tray. Do not cover the seeds with soil.
Place the tray in a plastic bag or cover it with plastic wrap and place it in a well-lit area where the temperature remains between 75 and 80 degrees Fahrenheit. Lightly mist the surface of the soil if it appears to be drying. The Fire begonia seeds should germinate within three weeks.
Transplant the Fire begonia into 3-inch pots, filled with equal parts of sand and potting mix, when they have their fourth set of leaves.
