It’s additionally vital to acknowledge dormancy habits so that you don’t suppose a residing plant has died on you, or a malingering plant is wholesome when it’s not.
Tuberous begonias, for instance, go dormant in winter even indoors, and drop their leaves and die again. Wax begonias have fibrous roots and should accomplish that effectively indoors that they not solely hold their leaves or develop new ones, they proceed to bloom.
Hardy begonias planted outside will die again naturally in Zones 6 to 9. When you plan to overwinter them in pots in colder areas, you’ll must trim the stems again your self.

If a pest inhabitants or harm is found however it’s minimal, eradicate the issue earlier than you take the time to winterize.
When pests are proliferating or crops are unhealthy, destroy these specimens, skip winterizing, and discover new choices for the subsequent rising season.
When you’re carried out planning, right here’s find out how to full winter preparations for the varied forms of begonias:
Carry Wax Begonias Inside for Winter
Outdated-school however ever-popular wax begonias are one of many best mass-planting flowers to overwinter and develop once more subsequent 12 months.

Put together for the transition by decreasing irrigation by half beginning in late summer season. By late August, stop fertilizing.
Rake plant particles from the backyard mattress or decide useless leaves and weeds from container-grown crops. The very last thing you need is to convey bugs or fungal ailments inside with the crops.
To ease their transition to a brand new indoor surroundings, pinch the stems again to a peak of about three inches. Some old-timers additionally pinch all of the flowers in late summer season, however I’ve discovered it’s sufficient to deadhead any which have turned brown.
Container-grown outside crops can transfer inside of their outside pots in the event that they’re not too heavy and you’ve got someplace to set or dangle them. Guarantee they’ve drainage holes on the backside and a saucer to catch extra water.
In the event that they’re rising in a backyard plot or panorama, you’ll wish to transplant them into light-weight, shallow pots full of a sterile, well-draining potting combine.
Bear in mind, whereas they want humus-rich soil to assist in drainage, they don’t want fertilizer through the winter, so keep away from premade mixes that comprise time-release fertilizer.
Dig up the crops earlier than you anticipate temperatures under 60°F to reach, and repot them on the identical stage they have been within the floor, backfilling with contemporary potting combine.

Water sparingly in winter, solely when the soil is dry to about an inch and a half under the floor, which you’ll be able to examine along with your pinky or a soil moisture meter. If unsure, skip the water since these ornamentals are notably liable to root rot from overwatering.
Through the winter, hold the crops wholesome by constantly deadheading the blooms, eradicating useless leaves with a pointy, clear paring knife, and instantly eradicating any plant particles from the soil floor to discourage illness.
These ornamentals don’t like transitions (I can relate!), so ease their stress by introducing them to new situations steadily.
Begin with just a few hours a day within the new location, whether or not shifting the plant to a hotter indoor spot in autumn or a cooler outside spot in spring.
Add an hour or two per day till every week has handed. By then, your begonia must be acclimated.

As a budget-stretching different, dig up and retailer the tubers through the chilly months. Then use them to begin new crops you may transplant outdoors in spring.

Go away the stems connected, however trim them to be an inch lengthy.
Let the tubers “treatment” in a cool, dry area like a shed or storage for a few weeks. This enables them to dry, so that they’ll keep contemporary in storage.
You’ll know that they’re prepared when the remaining stem stubs are unfastened and dry.
Then mud off any soil that’s nonetheless holding on with a high quality paintbrush or clear toothbrush, and nestle the cured tubers into a few inches of sawdust or a peat different in a cardboard container. I like to make use of shoeboxes, or one thing of an identical dimension.
Vermiculite
Natural vermiculite is my high decide for indoor gardening tasks like this one. Pure horticultural vermiculite is accessible in eight-quart baggage from Burpee.
Cowl the tubers with one other inch of sawdust or vermiculite and stow the field someplace that’s reliably 40 to 50°F.
They need to be high quality till you might be able to replant them outside or begin new crops from the tubers indoors. However do examine first to ensure the tubers haven’t turn out to be overly moist, mushy, or odiferous, and destroy any which can be.
Some of us like to make use of a separate small paper bag to comprise every tuber, so if one goes dangerous it received’t have an effect on the others and may be readily disposed of.

The center-shaped leaves are beautiful even with out blooms, however in addition they produce clusters of aromatic flowers in white or shades of pink.
They’ve a stunning trait of blooming from midsummer by late fall and are successful with pollinators.
As the times get shorter in autumn, they start to go dormant, with the primary signal being yellowing leaves.
The cool factor about these is that in dormancy, they kind pea-sized bulbils that can drop to out there soil and sprout into new hardy begonia crops come spring.
When you like, you may harvest these bulbils your self and plant them the place you’d wish to see extra begonias.
Hardy begonias have tuberous roots however the overwintering course of just isn’t the identical as you’d use for much less cold-resistant tuberous sorts.

Container-grown B. grandis can merely be moved straight into your chosen cool-but-not-freezing spot after the primary frost, however be sure you mulch the crops closely first.
Come spring, out they go, however solely after every week or so of hardening off of their pots.
