Double Begonias Mixture

Begonia x tuberhybrida


Begonias are in the Begoniaceae family and native to tropical and sub-tropical regions of the world. They are tender, like warmer temperatures and are a good choice to brighten up shady areas. Our tuberous begonia mix will produce double blooms of red, orange and/or yellow. They grow best in pots and window boxes.


Plant the rounded side down, dimpled side up, 1-2” deep in rich, well-draining soil. You may see pink growth tips on the upper side. Plant where they will receive morning sun and afternoon shade, and protection from heavy winds. Leaves and flowers will burn if the plant gets too much sun; too much shade will yield lush foliage, but few flowers. Begonias are notoriously slow growers and it can take 4-6 weeks before you see signs of growth. To get earlier blooms, you can plant the tubers inside 6-8 weeks before the last frost date in your area. Plant in pots or flats filled with a 50/50 mixture of moist peat moss and perlite, or potting soil mixed with equal parts peat moss and sand or perlite. Place the tubers just below the soil surface, as they may rot if planted too deeply. Water well; do not water again until planting medium is dry or you see growth. Keep warm, above 60°F; grow lights are not needed at this stage. Expect shoots in 5-6 weeks. Once growth is evident, move begonias to a bright location, such as a sunny window. Transplant outside after all chance of frost has passed, being careful not to disturb the roots. As with all plants, harden off over a two week period before moving them outside for good. Set them outside for a few hours the first day, in an area sheltered from wind and direct sun. Each day, leave them outside a little longer to build resistance to the elements.


Begonias require well-drained soil, but will not tolerate drought. Keep the plants watered, but allow the soil to dry slightly before watering. Avoid getting the leaves wet if possible and maintain good air circulation around the plants. For best bloom results, feed with a liquid fertilizer every 2-3 weeks during the growing season.


Begonias are tender plants and are only hardy in zones 9 and 10, where they may be left in the ground. Apply a protective layer of mulch in zone 9. Treat begonias as annuals in colder zones or dig them up to store inside for the following year. After the first frost, dig up the tubers and store in a frost-free location out of direct sunlight for a few days. Remove excess soil and old foliage and roots. Do not wash the tubers. Store them in dry peat moss or vermiculite in the dark between 35 and 50°F. Check occasionally for rot and discard any bad tubers.
