The Best Soil for Begonia Flowers


Begonias are annuals that grow from spring to fall, and die at the first frost. They bloom in oranges, yellows, pinks, reds and white, but only succeed when they get the right amount of sun and good, solid nutrition.


  • Begonias require quick drainage in their soil, and suffer in standing water, so it’s important that any begonia site drain quickly after rain. Gardeners should supplement this drainage by adding quick-draining soil or loam to the soil at planting.


  • Begonias also require nutrition and moisture retention, and fail in drought or poor soil. Add organic compost to the soil at planting to help retain moisture, further loosen the soil and add long-lasting nutrition.


  • According to the University of Vermont Extension website, begonias require regular feedings if they’re to succeed. Gardeners should add balanced 10-10-10 fertilizer at planting, and then side dress the begonias with this fertilizer once a month.
