Overwintering Begonias

Some Begonias go dormant for the winter and others have no dormant period and continue to grow and flower for the entire winter.

Contributors: Dr. Rick Schoellhorn

As fall approaches many gardeners want to bring their flowers indoors to keep enjoying them into the fall and winter months. Begonias are often a problem for many people because Begonias differ so much in the way they grow. Some Begonias go dormant for the winter and others have no dormant period and continue to grow and flower for the entire winter. Knowing which Begonia your have can help a lot of having success with bringing the plants indoors for the winter.

Some basics:

When bringing plants indoors from an outdoor garden area there are some basic do’s and don’ts to consider. The first priority is to make sure your plants are free of insects or disease before bringing them in for the winter. Indoor conditions are very stressful to most plants and when plants are stressed they are more susceptible to insects and diseases. So before you bring plants in for the winter you may want to give them a good looking over, it will save you problems later in the winter when you may not want to use chemicals indoors.

Indoor conditions are generally lower light than outdoors, so plants will have to adjust to lower light levels, sometimes they can do this easily and sometimes they must drop their outdoor leaves and grow new leaves that are better adapted to interior conditions. Plan for some leaf drop until plants become established again. All Begonias need bright filtered light when brought indoors and can sometimes be grown in full sun, but be careful not to burn plants by exposing them to bright sun if they were grown in the shade previously.

The inside of your house is also very dry due to your heating system which removes water from the air as it heats the air in your house. You can make life a lot easier for your plants if you provide a source of humidity. Many people mist their indoor plants and while this helps it only lasts for a short period. A better long term solution is the use of a pebble tray under your plants where water can be added as it evaporates to keep the humidity higher around your indoor flowers. A pebble tray is simply a container that holds water filled with pebbles so that your plants sit on the pebbles and not in the water itself, water evaporates around the plant a creates a small “greenhouse” effect.

Begonia types:

Begonias are incredibly diverse, so knowing what type of Begonia you have makes it a lot easier to succeed in over wintering them. Also many people confuse the Strawberry Begonia (Saxifraga stolonifera) with a true Begonia, it is not related at all but does make a nice houseplant in bright windows through the winter.

Rhizomatous Begonias

This group is the easiest to maintain indoors and make wonderful house plants in a bright filtered light setting. The way to tell if you have a rhizomatous begonia is to look for the rhizome or thick stem creeping along the surface of the soil. 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. Examples of these Begonias include: Black Coffee, Last Laugh, Palomar Prince, and River Nile.

Cane type & bedding begonias

These two groups look very different but are both easy to keep over the winter. The Cane types include Angel Wing Begonias and also the Dragon wing types. These need very bright light to look their best, but not scorching sun. Keep lightly moist and lightly fertilized through the winter months. They never go dormant, so do not allow them to become very dry. Examples of Cane and Fibrous begonias include: Sinbad, Dragon Wing, Gum Drops, Buttered Popcorn, Maribel, Benigo, Burning Bush, Angel Wing, and all the bedding types usually sold for the landscape.


Rex Begonia

Rex Begonias are a bit more of a challenge for indoor growing, but with a high humidity level can be gorgeous indoors with bright filtered light. These plants like constant moderate moisture, high humidity, and regular fertilization. They do not go dormant, so never allow them to dry out, they are very sensitive to dry roots and quickly decline if not cared for. However their electrifying foliage makes them one of the most desirable plants for both containers outdoors and inside. If you can grow African violets, you can grow Rex Begonias, so give them a try. Examples of the Rex Begonias include: The Great American City Series, Fire Flush, Capricorn, Taurus, and Fairy.

Tuberous & Tuberous types of Begonias including B. boliviensis

OK, if you have succeeded with other Begonias here is your final exam. The tuberous Begonia group REQUIRES winter dormancy. This means you need to begin in fall by reducing the water to the plants until the tops have died back and the soil is completely dry. Once the plant has gone completely dormant most gardeners remove the tuber from the soil. The tuber is usually found where the stems meet the ground. Carefully clean off the tuber of soil and old roots and store in a warm dry location over the winter.  Some gardeners swear by a fungicide powder to control diseases on the dormant tuber, this can be applied before storing the tubers.

In early spring the tubers may be replanted in fresh soil and given a head start on the season in a bright windowsill where they do not become chilled. The tuber should be planted so that the upper surface is at the surface of the soil, no deeper. When planting the tubers, water them well with a light fertilizer and do not water again until either the soil dries or you begin to see new stems emerging from the soil. Most gardeners start their tubers in small pots 4”-5” this way they can be transplanted into larger pot later but they do not become too wet during the crucial period where they waking up and beginning to grow.

New growth means your tubers are beginning to grow new roots and need to given fertilizer and water on a regular basis. Never allow tuberous begonias to become soggy, they are very sensitive to root rot if they stay too moist. Examples of Tuberous type Begonias include the following: Illumination, Non-Stop, On Top, Ornament, Panorama, Pin Ups, and Charisma series.

As with all garden plants brought indoors for the winter, you may have good luck and you may not. Remember that if all of this seems like too much work you can simply buy new plants in spring and start clean. Also Begonias can be prone to a variety of bacterial and fungal problems, especially under indoor conditions, so if you see problems of this type showing up during the winter, contact your local garden center for advice on how to control any problems.

Hi! Just found this site as I am looking for some help with my gryphon named Ruby Begonia. She is at least 10 years old and was about 4 ft tall, but didn’t overwinter as well this year. She has become very odd shaped & her stalks are about 2-3” in diameter and dying. They do get some new growth on the ends but they are not healthy. I want to cut off the stalks and shape her up, but not sure of the best way to do this & when I should do it. I really would like to save her! Thank you for any help you can offer.

I cut off a few blooms the beginning of October and brought inside in just a cup of water and put in window sil....the stem is still alive and still blooming. I have almost zero knowledge of flowers....this just seems really strange that it’s still alive. No soil...just basically 10 or 11 weeks now

Begonias can do that. Give it some more time and you might get roots on your stems and you can plant them up for next year.

Okay in reading on overwintering tuberous the wording "MOST people remove the tuber" appears. Does this mean if after you let it dry out you can leave it in the fiber pot in a cool dark place? How long does it have to be allowed to be dormant? Does it always need new soil in the spring?

You can leave them in the fiber pot and just bring them out again in the Spring, but I don't believe that method is as  foolproof as removing them and storing them for the winter and then replanting again in the spring.

I keep my Gryphon in a north window during the winter and by spring, all the leaves have dropped. After returning it to a shady spot outdoors in the summer, it becomes massive and gorgeous again. Does it require dormancy during the winter, or is there something that I can do to encourage foliage indoors in the winter?

Kerry Meyer's picture
Kerry Meyer Tue, 10/02/2018 - 4:34pm

I think you might be better off putting it in a spot where it gets more light.  Since it bounces back in the spring and looks awesome in the summer, you don't necessarily need to change anything, but see if a brighter spot helps it to maintain foliage all winter.

Hello - Thank you for your informative article. I still am unsure of what to do with my approx. 5 year old Rex Begonia, Escargot. I have had no trouble with this plant for many years bringing it in and outside of my Southern New Hampshire home at appropriate times. It usually gives off an abundance of flower stalks sometime while it is indoors. I vacationed in May 2018 and when I returned it was totally dead looking. Apparently it was a very warm week and it dried out . I brought the pot outside to a shady spot and it still has done nothing. The Rhizome is showing at the surface of the soil and is a good size in this 8.5" round,6"tall clay pot. It does not seem to be squishy as if it is rotted since being left out in the shade. Can you give me any suggestions or opinion on the status of this plant? I am hoping it has gone dormant due to lack of water and will come back. Seems odd that it survived many winters, but went down at a few days of neglect in Spring. I do not feed it often. I have a sunroom full of plants, and an outdoor garden that thrives despite not being fed as often as they should be. I appreciate any response!

Kerry Meyer Tue, 10/02/2018 - 4:22pm

If you haven't already removed the the dead foliage, that would be the first thing to do. Then water as necessary and be patient.  As long at the rhizome seems fine I think you have a reasonable chance of it bouncing back. Do NOT overwater it as that would be problematic.  Moist, not wet is the goal.  Then just give it time to bounce back.

Rick is in New Zealand and Australia for the next 5 weeks - he's SO lucky!  So you are stuck with me, instead of Rick who is true expert when it comes to Begonias.  If they look really dried out I think you are probably out of luck after two years.  However, giving them a soak for a bit and re-evaluating would be pretty low-key.  If they look better after some moisture, go ahead and pot them and see what happens. If it doesn't seem worth your time and effort, buy new and go from there.

Hello and good afternoon. I was given a begonia plant 5 years ago. This person said she has had it for 15 years before she gave it to me. I have re-potted it twice during that time. It is in bloom right now and growing so fast I will have to re-pot soon. It has green leaves with seven point leaves. It has red veining and some red under the leaves. The leaves are speckled with lighter green. The flowers are green with yellow pestle and the seed pods are green with red on the outside.I have kept it inside facing north in the kitchen window. I love this plant and just want to make sure I am doing everything I need to to take care of it properly.

If you have the plant and it is growing well, it should be fine once spring comes and you can just move it slowly outside with some shade until it adjusts to life outdoors. It should flower once it is adjusted and growing well!

I live in Vermont and have a yellow begonia I'm trying to keep over the winter. I kept it outside in a pot in the summer and fall and brought it inside before frost hoping it would continue to bloom inside. The blooms finally faded and dropped off. It looks like "Illumination" on your website but I'm not sure. The flowers look like that variety but each bloom had a second flower next to it with single petals (5 or 6). The stems are thick and the leaves are pointed. I wish you had another photo showing the whole plant so I could be sure. I kept it in a north facing window with good light but no direct sunlight but the leaves on one stem started showing mildew. I removed some of the leaves. Was this ok? I plan to spray it with a water hydrogen peroxide solution, is that ok? Any advice on how to overwinter this plant would be greatly appreciated. I would love to put it outside again next summer. Thank you.

Hi there -
OK so your Begonia is a tuberous Begonia and it wants to go dormant as winter approaches, the cooler temperatures and shorter days all tell it to slowly die back and rest through the winter. So you can leave your plant in the window sill but stop watering and let it slowly go dry and wither down to it's tuberous root. Perfectly OK to remove any leaves with powdery mildew but don't cut it back until it has completely dried out. Once the soil is no longer damp you can put in a closet or storage space (temperature around 40 deg) and leave it through the winter until next spring. Then carefully life the tuber from the soil, repot it in a new pot and grow it in a windowsill until you can go outside with no danger of frost.
There is a more detailed description of this in the article at this link:

Best of luck and Happy Holidays!

Does this begonia go dormant in winter? After bringing it indoors, all leaves have become dry and shrivel up at the edges and eventually die. I have watered only on the sparse side. Can I save this begonia? Margaret

Rick Schoellhorn Tue, 11/21/2017 - 7:41am

Hi Margaret -

Readjusting a Rex Begonia, like escargot, to indoor conditions is always touch and go. But this type does not go dormant however, they do love high humidity and most indoor situations involve hot dry air coming from your home heater - and that makes for rough times on Begonias. Also there is a lot less light indoors, much less than deep dark shade outside, so the plant has to lose a lot of leaves that it can't support anymore indoors. But don't give up. Here are some tips:

Try placing the plant in a window with bright morning sun, nothing scalding hot, but well lit.
Make a pebble tray to go under the plant so there is a source of humidity to help fight off the indoor dry air burning the leaf edges. Here are some ideas on keeping humidty higher around your houseplants:
Also misting the foliage can be helpful, but generally something like a pebble tray is less work for you and more constant moisture for the plant.

You are right to keep watering low, Begonias hate soggy soil, so keep that up all winter.The key thing with Begonias is consistency, so keep the plant lightly moist at all times, avoid big swings in watering where the plant gets very dry and then when watered stays very wet. Begonias like a constant level of moisture.

Best of luck!

This morning when I looked outside, my begonias, which until yesterday still had foliage and even a few flowers, are suddenly all limp and dead looking!
They are protected under a canopy but obviously last night's cold got them.
Do you think they will come back?
I plan on cutting all foliage and storing them as advised, is that OK?
I was given these beautiful plants a few weeks ago, having never had begonias before, I hope I didn't massacre the poor things!
Thank you!

OK so first off, they were going to go down anyway, so there is no reason to feel bad, however a freeze means you'll need to be extra careful and avoid things getting too wet before you go into dry storage for the winter.
I would say you should quickly get these plants into a dry, protected from freezing place and don't cut them back but just dry them out, once they are dry you can cut them back.
Otherwise I think they will hopefully be fine!

You can do this a couple of ways.
1) Bring it in as an indoor house plant, put it in indirect sunlight. Keep it dry, water about every other week or every third week.

2) Put in a cool basement. Not much sunlight, water once a month. It will drop it’s leaves, leaving only the stock left by Feb.
Take outside when all danger of frost has passed.

When bringing in any outdoor plant make sure to inspect for pests, water well with soapy water to flush out any critters. You can transplant, but this is best done in the spring when you get new growth.
No fertilizer is needed until spring.

I would like to overwinter an Unbelievable Miss Montreal begonia. Does this begonia type need a dormancy period or will it keep growing indoors? I am trying to root a cutting from the same plant, and have managed to achieve some small roots on the cuttings on my second try (the first ones rotted in water), but I am not sure yet whether I will have any success in getting them to grow in soil. Can this begonia type be propagated by leaf cuttings?

Rick Schoellhorn's picture
Rick Schoellhorn Tue, 10/24/2017 - 5:15pm

Hi there!
OK so Miss Montreal is a typical tuberous begonia, so it must go dormant. The article will tell you how to do this but it really just means stop watering it and let it die back to the tuber below the soil. No more fertilizer and really best if you can keep it in the shade or a dark area once it is mostly dry. Then in spring bring the pot back out, place it in a bright window, and moisten the soil, you should see new shoots within a week or two.

It really can't be overwintered and kept growing.

Best of luck!

Hi, I have some beautiful trailing apricot Begonias and they, have grown beautifully. I would like to grow them on next year but i have no idea how to do this. They do not have a corm, i bought them from a local shop and they were already in little potting pots. I assume this means they were seeds originally, so do i have to do cuttings? I really am a novice at this but would appreciate any help or advice that you could give me.

Rick Schoellhorn's picture
Rick Schoellhorn Wed, 10/18/2017 - 10:24am

OK so there are many kinds of Begonias and they need a bit different care depending on the type you have, but if you have Apricot trailing types they are most likely tuberous, even though they came in pots when you bought them, as they go dormant this winter they will send that energy into their roots and the developing corm. Is there a name tag in the pots? That would help to positively identify the plants?

So for tuberous begonias you want to start letting them get drier and stop all fertilizing as the nights get colder, they will not tolerate a freeze, so protect from any nights that are that cold. Essentially you job is to tell to go to sleep by reducing water, until the pots have dried out. Then you either dig up the plant and store the corm/tuber or simply moved the already potted plant into an area that stays around 40 degrees. It can be a good idea to apply a systemic fungicide while the plants are still growing, that way they pick up the fungicide in their tuber and that helps it to survive over the winter without rotting.

What you don't want is for the plant to kept wet and cold as that will definitely cause the tuber and stems to rot.

So ease the plants into a cold dry dormancy for the winter, and then next spring when it is warm, bring them back out into the light and transplant them once you see new shoots emerging from the soil!

Best of luck!

Rick Schoellhorn's picture
Rick Schoellhorn Wed, 10/18/2017 - 10:15am

OK so for overwintering plants in a greenhouse the rules are the same as if you were bringing them indoors. We have an article on that and the link is here:

The main thing is to do your pruning and spraying for any disease or insects BEFORE you bring the plants into the greenhouse, otherwise the whole winter will be spent trying to take care of problems in the tight confines of the greenhouse. Once inside the greenhouse any disease or insects also can easily jump from one plant to the next making your life, So it is easier to do all that while they are outside.

Have fun and enjoy the greenhouse and winter color!

I overwintered my 4, 10" pot, hanging basket Dragon Wing Begonias and it went well. Now, it is time to acclimate them outside.


Last year, my nursery told me to cut the plant into 2 plants and plant both of them. Now, today, the same person at the nursery told me something completely different. She said to cut the bottom "dome" of the root ball off. Then, cut the sides off the root ball to make it a square. Then, put the plant back in its pot and add new soil to fil in the cut off areas.

Surely, the plant has to be root bound after being in the same pot for an entire year. And, I cannot go to a larger pot. So, what steps do you recommend I do now to ready my plants for the upcoming year?

Thank you,

Hey there Rick -
OK so if you need to replant them in the same pots and want them to have fresh soil to grow in for the year, reducing the root ball by 1/3 to 2/3 is fine. They are pretty darn tough. I personally would avoid splitting the plant into 2 plants since it is so much harder on the plant (unless of course they are obviously separate plants to begin with), where just reducing the size of the rootball and replanting is actually easier on the plant over all.

Keep them moist but not soaking wet (root rot can be a problem if they are very wet) and especially if they are in low light. Definitely give them some fertilizer to encourage new root formation.

Begonias have a very fine hair-like root system, so they will rebound fairly quickly from a trim.

I hope this helps and have a great weekend!

I have brought my begonias in for the winter and most of them have died off. Now some of the survivors have white dusty spots on the leaves. The new leaves look shiny and healthy but this whatever it is is spreading. Is thee hope? Or should I ditch all the planters, the plants and the dirt. The crop has been decimated with maybe only 10% still alive. They are in a spot with indirect lighting in my kitchen bordering on the deck.

Hi there!
OK so I believe your problem here is powdery mildew, many Begonias can get it and especially under indoor conditions. Your best treatment is to apply a fungicide that specifically controls powdery mildew. Something like this product: which is natural might work.

IF the begonias you are talking about are the types with very large rose-like flowers (called Tuberous Begonias) this might get you through until spring. Most tuberous begonias should be allowed to dry out entirely as fall turns to winter, and then you can store the tubers in a cool dry place, like a garage or unheated closet, and then replant the tubers again in spring. This is a lot simpler and easier than trying to keep them alive and growing all winter.

I hope this helps! Yell if you have more questions!

I would encourage you to really back off of the watering, most begonias will actually do much better with a drier soil base that drains well. The foliage and the stems are great moisture reservoirs which allow the plant to survive and grow with the need for constant irrigation. What I would encourage is slowly back down your watering regime until the soil is moderately dry, new foliage should start to sprout, and then start a new with a mild water soluble fertilizer and a thorough watering. It is far better to water thoroughly but less often. Hope this helps, and enjoy your begonia parenting.
