Fill your summer flowerbeds with versatile and vibrant begonias. Begonias are especially suitable for flowerbeds because they grow easily and spread out to create a carpet of blooms. With minimal care, begonias will establish themselves readily and soon will be thriving in a sunny or partly sunny growing spot. Give them fertilizer periodically throughout the summer and remove the spent blossoms, and you will have a beautiful flowerbed.
Cultivate the soil of the flowerbed to a depth of at least 6 inches with a garden spade after the final spring frost. Sprinkle at least 2 inches of compost on top of the soil. Work the compost into the soil with a garden spade and rake the flowerbed surface smooth.
Dig holes for the begonia plants, spacing them approximately 6 inches apart. Make the holes deep enough that the begonias will be at the same depth as they were in the temporary containers.
Place the begonia plants into the prepared holes. Fill the soil in around the roots of the begonia plants and firm the soil down lightly with your hands.
Water the newly planted begonia plants to saturate the soil but not to the point of creating puddles. Water the begonia plants throughout the growing season when the soil dries. Wait until the soil dries again before providing more water.
Add 2 inches of shredded mulch around the begonias to conserve soil moisture and prevent weeds.
Fertilize the begonias once per month with an all-purpose fertilizer. Sprinkle the fertilizer into the soil around the plants. Consult the package recommendations for the amount of fertilizer. Work the fertilizer into the soil with a hand rake, taking care not to allow the fertilizer to touch the plant foliage. Water the begonias immediately after fertilizing to help the fertilizer reach the roots.
Deadhead the begonias with pruning shears when the blossoms fade. Clip off any blossoms, stems and leaves that fade and shrivel. Clip off the entire blossom stem to keep your begonia plants attractive as you remove the blossoms.
