Should begonias be cut back in the fall?
Cut back begonias in autumn. You should cut them back up to 1/3 of the plant after flowering. Throughout the year, prune your begonias to shape their growth. If you have winter-flowering begonias, cut them back in the spring after they have finished flowering.
Can you leave begonias in the ground over winter?
Leaving Begonias In The Ground As long as the type of begonia you have is hardy in your climate, then you can overwinter them right in the ground. If they have tubers, then they’ll survive as long it stays above 50° F. During the winter, the foliage on tuberous varieties may die back if the bulb goes dormant.
Can you save begonias for next year?
CORVALLIS – Many people enjoy the lush blossoms of tuberous begonias in pots on patios and as outdoor hanging plants. There’s no need to throw them away when cold weather hits and the tops die. The tubers can be saved over the winter and planted again the next spring for another year of showy color.
When should I bring my begonias inside?
Timing Is Important: Bring your begonias inside before the first frost, or they may be lost for good. Also, to reduce temperature and humidity shock, take advantage of that wonderful early fall season (when neither the heat nor air conditioning is running nonstop) to get your plants acclimated to the indoors.
How do you take care of begonias in the winter?
Begonias in this group like to be kept lightly moist and lightly fertilized all winter and do not go dormant, so never dry them out entirely. Most are winter flowering and can provide not only beautiful foliage but also sprays of white to pink flowers in late winter.
Do begonias need sun or shade?
Most begonias grow best in part shade (4 to 6 hours of direct morning sun a day), or filtered sun (as through trees). Most will tolerate full shade (no direct or filtered sun), but won’t be as dense and usually have fewer flowers. A few grow in full sun.
How do you care for potted begonias outside?
Outdoors, rex begonias like part- to deep shade, ordinary potting soil, and water when the top inch or so of the soil is dry. Give them a balanced liquid fertilizer once a month, or add granular timed-release fertilizer to the potting soil at planting time. Avoid misting the leaves; alkaline water just desiccates them.
How do you keep begonias alive in the winter?
Store begonia tubers individually in paper bags or line them in a single layer atop newspaper. Place these in a cardboard box in a cool, dark, dry location. You should also be overwintering a begonia grown outdoors in containers. Pot-grown begonia plants can be stored in their containers as long as they remain dry.
