Do Wax Begonias Come Back Every Year. Annual begonia plants may be cut back before frost and used inside as a houseplant in winter. What it is.
Only in zones 10 and 11. Begonias dont handle cold temperatures and frost well. Cut back bedding or fibrous begonias to 3 76 cm every 4 months in mild climates where there is no frost to renew the plants.
What it is.
Begonias are annuals so they wont grow back each year. Now your second question. Begonias dont handle cold temperatures and frost well so wait until at least one week after the final frost of winter to plant them. Most begonias die at frost but this one is a perennial version that sends up stems of nodding pink flowers from July into mid-fall then dies back to the ground.
