How to Care for Wax Begonias

Wax begonias are an easy low-maintenance annual. They come in a variety of beautiful colors, such as white, pink or red. Their glossy silky leaves make them seem almost artificial. Because of their neat appearance, wax begonias do well as a border for a flower garden or along a sidewalk. You can plant a wax begonia in a window box on the porch. Wherever you decide to plant the begonia, keep a few tips in mind for their proper care.

Slow-release granular fertilizer

Mulch

Plant the wax begonia in a partially shaded location in your yard, where they tend to do well. However, if the soil is kept regularly moist, wax begonias can grow in full sun.

Plant wax begonias after the last frost and the temperature remains above 60 degrees Fahrenheit at night. This will be in the beginning of spring for most regions. Place them about eight inches apart to allow for adequate growth room and air circulation.

Water very well after planting, and put down a 2-inch layer of mulch, such as pine straw or bark, to reduce weeds and keep the soil moist. Keep the mulch a couple of inches away from the stems to help prevent diseases. Water only when the soil feels dry to the touch.

Fertilize the wax begonias with a slow-release granular fertilizer after planting. They don't need much, though. Use about 1/2 tablespoon per plant if the soil is rich. Double that amount if it's a poor soil.

Pinch back leggy stems if needed throughout the growing season. Pinch back about a third of the length of the stem. This will also create a bushier plant.

You don't have to deadhead wax begonias because they will deadhead on their own.
