I have some beautiful wax and angel-type begonias in pots. Can I bring them inside for the winter? How do I care for them? – Robert


Both wax begonias and angel wing begonias are fibrous-rooted, which means they have a basic, familiar-looking stringy root ball.

These are the begonias commonly sold in hanging baskets and as bedding plants. Fibrous-rooted begonias make great house plants over the winter, as do the rhizomatous types (such as Rex begonias), which are grown primarily for their foliage.

All you really need is a little space and a bright window, and these types of begonias will continue to grow (and possibly even bloom!) year-round.

Bewildered by Begonias? To know how to care for your begonia over the winter, you really need to know what kind of begonia you’re growing.

Fibrous and rhizomatous begonias are easy to grow as house plants, but tuberous begonias need to be stored as bulbs over the winter, and hardy begonias should just be left outside.

If you aren’t sure what kind of begonia you have, check out our article on How To Grow Different Varieties of Begonias.

How To Overwinter Fibrous and Rhizomatous Begonias

Follow these tips for overwintering fibrous and rhizomatous begonias indoors.

  • 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.
  • Leave in Pots: To save the work (and plant stress) of potting your bedding begonias, try nestling them in the ground in pots that are easy to lift out in the fall.
  • Repot if Necessary: Spring is the traditional season for repotting begonias, but if yours are so rootbound that they’re struggling, go ahead and move them to a bigger pot before bringing them indoors for the winter.
  • Trim Back: Lightly pinch or trim back leggy begonias to shape them up. If you’re digging up bedding plants or repotting a rootbound plant, cut back the tops to about the same size as the root ball.
  • Inspect Carefully: Don’t bring pests or diseases indoors! Throw away any begonias that look diseased or infested, and treat minor problems before bringing them inside.
  • Light: Bright filtered light is ideal, with perhaps some winter sun from an east-facing window. Blooming types of begonias like more sun than foliage types. Even though the light is dimmer indoors, be careful of too much sun exposure, especially if your begonias are used to growing in the shade.
  • Water: Keep begonias evenly moist, neither soggy nor dried out. Begonias don’t like “wet feet,” so empty the drainage tray or decorative planter after watering, so that they don’t sit in a puddle.
  • Fertilizer: Feed your begonias lightly throughout the winter. These types don’t go dormant, but they will slow down some over the winter. A good rule is to feed them more when they’re growing, and less when they slow down.
  • Temperature: Keep your begonias between 65° to 73° F during the day, and no colder than 55° F at night. Be aware of drafts and freezing window glass that might damage foliage.
  • Add Humidity: A pebble tray will help give your begonias extra humidity to cope with the change in environment. If you’re overwintering Rex begonias, they might need misting or a little help from a humidifier.
  • Adjustment Period: Some begonias respond to the shock of moving indoors by dropping and regrowing some or all of their leaves. Don’t worry, just pinch back leggy stems and keep on taking care of your begonia until it grows new leaves.

Further Information


  1. This advice was exactly what I was looking for. Very helpful.
    My begonias did well this summer. Lots of rain and sun I guess. I hate to see the potted plants die in the fall so I will follow this advice.
    Thanks a million

  2. Thank you for your much apprecated advice. If i put my beddng beonias in an unheated green house but cover them with fleece might they suvive? I do have a small parafeen heater and candels, which I use with terracote pots and this keeps frost away. Please reply and many thanks

  3. I have 2 hanging baskets of the Encanto Waterfall Begonia that still have beautiful flowers on them. Live on the east coast so brought them in today. How can I keep them over the winter? Where should I place them, watering etc….

  4. This information was very helpful. I also brought my beautiful watering can filled with wax begonias and Angel wing begonias
    inside because I didn’t want to lose them! I purchased this arrangement at a garden shop in early summer here in the Rochester New York area and it was such an enjoyable thing to display on my patio table!
    Another question is, will the begonias outside come back up in the spring?
    Thank you so much

  5. This advice is wonderful thank you. I have the most gorgeous orange begonia that I would hate to lose to frost so I am bringing it indoors. It’s huge so heaven knows where I will put it

  6. Thank you! Thank you! Thank you! I take care of my Mother’s plants and I <3 it! Her begonia and I aren't getting along! The info you shared is just what I needed!! 🙂 Thanks again!

  7. I live in Texas and I trimmed down and mulched my bedded wax begonias. My potted begonia (also wax) I brought inside. And have been keeping it up. Yesterday I noticed mold on the soil top. Any tips to keep the mold out of my begonia’s soil?

  8. Thank you so much for the information! I have 2 Begonia plants that have thus survived the winter inside. However, they are getting quite leggy or stringy. I was afraid to cut them back.

  9. Thank you so much for the information! I have 2 Begonia plants that have thus survived the winter inside. However, they are getting quite leggy or stringy. I was afraid to cut them back. The stems have new growth on them, but they wither and turn brown. How far can I cut them back?
    Also, I tried using a growth hormone to start another plant. It didn’t take. How can I start more Begonias from the 2 I have? Much appreciated!

  10. My daughter bought me a small pink budded one should I replant it in more soil as it’s winter in Indiana and can I keep it potted and place it outside

  11. Thanks for this information. Being on Canadas west coast we can get lots of rain, and some frost, I will see how they do indoors…
