Care for a Begonia X Tuberhybrida


Begonia X Tuberhybrida, or tuberous begonias, are flowering plants that can be grown in semi-shady flower beds, window boxes, patio pots or hanging containers. Tuberous begonias are available in a variety of hues including pink, white, yellow, orange and red, with single, double or ruffled blooms. Although tuberous begonias are perennials, they are frost-tender. However, they can be removed from the soil, wintered over and replanted the following year.

Step 1

Plant tuberous begonias in partial shade outdoors in late spring. The plant will do well with morning sunlight but must be shaded during the afternoon.

Step 2

Water tuberous begonias once every week during dry weather. Tuberous begonias planted in containers should be checked daily and watered whenever the soil feels dry to the touch.

Step 3

Fertilize tuberous begonias every other week. Look for a balance liquid fertilizer with numbers such as 14-14-14. Follow the directions on the fertilizer package, except dilute the fertilizer to half strength.

Step 4

Remove spent blooms from tuberous begonias to encourage the plants to continue to bloom as long as possible. If the wilted blooms are allowed to remain on the plant, the plant's energy will be used to make seeds instead of blooms.

Step 5

Dig up tuberous begonias if you live in a climate with freezing winters. Dig the begonia with a garden fork or spade. Cut the stem down to about 1 inch, and leave a bit of soil on the tuber. Allow the tuber to dry in a cool room for two to three weeks, then store the tubers in a cardboard box or a paper bag filled with dry sawdust or vermiculite. Store the tuber at 40 to 50 degrees F and don't allow the tuber to freeze.
