The Time to Plant Begonias

Native to tropical South America and southern Africa, begonias are versatile plants that grow well in just about any shady spot in a landscape, from pots and planters to borders and flower beds. For beginners, begonias are best grown from starter plants and will offer the best performance when set out at the proper time.
  1. Time to Plant Begonias

    • The best time to plant begonias is in mid-May or after the threat of frost for your region.

    Types of Begonias

    • The tuberous begonia is the one most often sold at local garden centers. It grows in a wide range of colors, including pink, red, white, yellow, orange and bi-colors. The blossoms of these plants may be single or double, ruffled or plain, according to Iowa State University Extension. Begonias are also available in an array of hybrids that offer a diverse display of form and color, with blooms of some varieties reaching up to 9 inches in width.

    Place to Plant Begonias

    • Choose a site that has well-drained soil, partial shade and shelters from strong winds, advises Iowa State University Extension. Sites that offer morning sun but afternoon shade are ideal. Total shade is not desirable as the plant will not produce any flowers, according to Plant-care. Begonias also grow well in acidic soil, not ordinary garden soil. A combination of coarse leaf-mold, peat moss, coarse sand and rotted cow manure provide a good balance of nutrients, says Plant-care.

    Caring for Begonias

    • Begonias like water, but not too much. Keep the soil moist without being soggy, recommends online resource Plant-care.com. The frequency of watering will vary depending upon planting site. Begonias planted in borders and beds should be watered once a week in hot weather; container grown plants will require more frequent watering. Avoid using alkaline or hard water on the plants. To promote blooming and proper growth, fertilize begonias with a diluted fertilizer throughout the growing season, advises University of Minnesota Extension.
