Growing begonias is fun, and you can enjoy them both in your garden or indoors. Learn everything there is to know about them in this detailed begonia plant care guide.
In this article, I’m going to give you tons of care and maintenance tips, show you how to fix common problems, answer your FAQs, and much more!
If you think that begonias are only good for growing in your garden, think again! There’s no doubt that they add tons of color to the garden, but many varieties can also be kept indoors as houseplants.
That means you can grow your favorite varieties for years to come, either indoors or out. And it’s easier than you might think. Yaaaas!
Below I am going to show you exactly how to care for begonias. I will give you tons of information about them, including the different types, hardiness, growing them indoors or outside, fixing common problems, and more!
Information About Begonias
Before you can become a begonia care ninja, it’s important to understand some basic things about them. First, there are tons of different kinds that you can grow (and collect!).
Some can easily be kept as houseplants, while others are a synch to overwinter. But one thing is for sure, all of them add amazing color, both outdoors and inside the house.
Different Types Of Begonias
There are over a thousand different kinds of begonias, and they come in a wide variety of shapes, sizes, and colors.
Some are adored for their gorgeous flowers, and others for their amazing foliage colors and patterns. At a high level, there are four common types of begonia plants:
- Tuberous – (e.g.: Rieger begonias) These begonias have bulbs (tubers) and large flowers
- Rhizomatous – (aka: Rex begonias) These begonias are mostly grown for their gorgeous foliage
- Cane – (aka: Angel wing begonia) These begonias are usually large, showy, and constant bloomers
- Fibrous – (aka: Wax begonias) These begonias are common bedding plants famous for the prolific flowers
The different kinds of begonias don’t all require the exact same care. So it’s best to figure out what type you have so you know if it requires any special treatment.
Are Begonias Annuals Or Perennials?
Though they are commonly sold as annual plants in cold climates, begonias are actually tropical perennials that can live for many years.
Some are only hardy to zone 9, while others can survive in colder climates down to zone 6. It’s best to look up the exact variety you have if you’re unsure how hardy they are before planting begonias outside.
Begonia Flowers
With the proper care, many types of flowering begonias will bloom year round. However, some of the rhizomatous varieties don’t flower at all, but have amazing foliage.
Don’t worry, what they lack in flowers, these begonias more than make up for in unique and colorful leaves.
In fact, many avid growers prefer the non-blooming types because you can’t beat their stunning foliage.
How To Grow Begonias
As I’ve already mentioned, begonias can grow either outside or indoors. So in this section, I’ve broken it down to give you specific details about caring for them both outdoors and inside the house.
Growing Begonias Outdoors
Begonias are wonderful for adding tons of color to a shade garden, or combined in mixed outdoor patio planters. Choose a spot in your garden that has rich, well-draining soil.
If you have poor-quality soil, you can amend it with worm castings, compost, or an organic all-purpose fertilizer before planting.
Most begonias grow best outdoors in partial shade or dappled sunlight. They can survive in full shade, but might not bloom very well if they don’t get enough sunlight.
Growing Begonias Indoors
Once the weather gets too cold outside, you can bring your begonias indoors, and grow them as houseplants. Heck, many types will even grow great indoors all year round!
Place them in a spot where they get bright, indirect light, and keep the soil consistently moist. Begonias do best in a home that is kept between 65-75 degrees F.
If you want, you can move them outside during the summer to give them a boost. Just be sure to wait until all chance of frost is gone before putting them outdoors in the spring.
Begonia Care Instructions
No matter where you choose to grow them, the good news is that the basic begonia plant care requirements are the same for all types. Follow the tips below for the best success.
Water
Proper watering is one of the most difficult parts of successful begonia plant care. That’s because they like to be kept evenly moist, but won’t tolerate being overwatered. It can be a difficult balance.
Rather than watering begonias on a set schedule, you should always check to make sure they need it first.
Stick your finger about an inch into the soil. If it feels wet, then let it dry out a bit more before watering again.
If you struggle with getting it right, then I recommend using a soil moisture gauge to help you out.
Indoors they do have a greater risk for fungal problems and rot if the leaves get wet. So to avoid any issues, it’s a good idea to water begonias from the bottom.
To do that, simply fill the plant tray or cache pot, and allow the soil to soak it up through the drainage holes.
Don’t let the soak for too long though, only to the point where the soil is moist again. Dump out any water that hasn’t been absorbed after 20 minutes.
Growing begonias in African violet pots is a great way to make bottom watering easy, and it will also help prevent overwatering.
Humidity
Like most tropical plants, begonias like a lot of humidity. This usually isn’t a concern when they’re growing outside, but can be a struggle indoors.
Humidity is especially important during the winter months, since heating our homes makes the air even dryer than normal. An indoor humidity monitor is a good tool to use to keep track of how dry the air is.
There are several things you can do to help increase the humidity to a level that will make your begonias happy.
Try running a humidifier near them, or place them on a pebble tray filled with water (don’t allow them to sit in the water though).
You could even grow small begonia plants in a decorative cloche, or keep all of them in a mini indoor greenhouse for the winter.
Sunlight
Some begonias need more sunlight than others, and there are new varieties on the market these days that can even handle full sun.
But most will suffer if they get too much sunlight, and it can burn their tender leaves. In general, they prefer a partial shade location where they are protected from the intense afternoon rays.
Indoors, you should grow begonias in a spot where they get bright, indirect light. An east or west facing window would be the perfect spot.
If the leaves start to turn white or faded, or look like they’re burning, then that means it’s getting too much sun. In that case, move it to a shadier location.
On the flip side, if the stems start to grow leggy and reach for the window, then they’re not getting enough light. Move it closer to the window, or add a grow light.
Potting Soil
Begonias aren’t super fussy about the type of soil they’re planted in. But ideally, they prefer one that is fast draining, and also holds moisture.
You could certainly use general purpose potting soil, and that will usually work just fine for them. An African violet potting mix also works well for growing begonias.
To help the soil retain moisture, or if you tend to under water, add peat moss and/or vermiculite to the mix before planting.
Outdoors, you can amend your garden soil with compost, worm casting, or peat moss.
Fertilizer
Begonias will benefit from regular feedings during their active growing season (spring and summer). Start by giving them a weak dose of half or quarter strength liquid fertilizer in early spring.
Then gradually increase the dose, so you’re feeding them weekly as part of your regular begonia plant care routine during the summer.
They can be sensitive to chemicals tough. So I highly recommend using an organic flower fertilizer on them, rather than synthetic ones.
A good quality organic compost fertilizer is always a great choice. You can buy it in a liquid concentrate, or get tea bags and brew your own. Organic African violet fertilizer also works great for feeding begonias.
Instead of liquids, you could mix a granular fertilizer into the soil a couple of times throughout the summer, if you prefer. Stop fertilizing begonias in the fall, and don’t feed them at all during the winter.
Repotting
The best time to repot is in the spring, but only do it once they’ve outgrown the container. Begonias like to be root-bound, and can struggle if repotted too often.
When it’s time for repotting begonias, be certain to choose a container that is only one size larger than the current one. They can start to suffer if they’re planted in a pot that’s too large.
Always use a container that has drainage holes to prevent overwatering. Also, pots that are made out of plastic or ceramic are better choices than terracotta. Clay wicks moisture out of the soil, and it ends up being too dry for growing begonias.
Pruning
Regular pruning is a great way to keep begonias growing and looking their best. Deadheading the faded flowers also helps to encourage new blooms.
Spring is the best time to trim them for shape and size. Pruning begonias in the fall or winter can result in weak and leggy growth.
But you can prune dead leaves and flowers at any time during the year. You can simply pinch out the spent flowers, but be sure to use a sharp pair of precision pruners to avoid damaging the plant while trimming the leaves and stems.
Pest Control
Another awesome thing that makes begonia plant care even easier is that they don’t usually have much trouble with houseplant pests. Yes!
Fungus gnats and mealybugs are the biggest risks, so keep an eye out for them.
The presence of gnats in the soil is a sign that you’re overwatering. The best way to get rid of them is to allow the top inch of soil to dry between waterings. You can also use a yellow sticky trap to help control them.
Bugs on the leaves are pretty rare. But if they do appear, it’s best to treat them by hand rather than spraying anything on your begonias. Dip a cotton swab in rubbing alcohol, and use it to kill and remove the bugs.
Many times you can wash the leaves with a diluted mild liquid soap and water. But some begonias are sensitive to this, so be sure to test it on a few leaves before washing the whole plant.
Begonia Propagation Tips
You can propagate mature begonias from leaf or stem cuttings, by division, or even by collecting and then planting the seeds.
The cuttings are pretty easy to root, as long as they get enough humidity. For best results, take cuttings that are a couple of inches long, and include a few leaf nodes. Remove some of the lower leaves, as well as all of the flowers and buds.
Dip the cut end into rooting hormone, then stick it into a light airy soilless mix of peat moss, vermiculite and perlite or pumice.
Keep the soil consistently moist, and be sure the air around the cutting stays very humid. I have found that it’s much easier to use a propagation chamber, and I’ve had the best success with that.
Learn all you need to know about how to propagate your begonias in my step by step guide here.
Seeds
Growing begonia seeds is definitely the hardest (and slowest) form of propagation. They can be a bit difficult to grow from seed, but it’s fun to experiment.
If you want to try saving seeds from your begonia, then don’t deadhead the flowers. Seed pods will form where the flowers were.
Allow the pods to dry on the plant, then collect them in a small bowl. The seeds are tiny (like dust), so don’t attempt this when it’s windy!
Bringing Begonias Indoors For Winter
If you put your begonias outside for the summer, make sure you bring them back indoors before it gets too cold, or they could start to suffer.
It’s best to bring them inside before the temperature gets below 60 degrees F in the fall. They don’t like to be cold, and the shock might be too much for them to survive.
Tuberous varieties are the only ones that can’t be kept as houseplants, they prefer to go dormant during the winter. Learn how to overwinter tuberous begonias here.
Troubleshooting Common Begonia Care Problems
The most frustrating thing about growing begonias is when they start having problems, and you have no idea what’s wrong.
So, in this section, I’ve listed out some of the most common problems, along with the probable causes, and solutions.
Leaves Turning Brown
Most of the time, brown leaves means they aren’t getting the right amount of water (usually under watering). But can also be caused by lack of humidity or extreme temperatures (freezing or sunburn).
Ensure the soil stays consistently moist, and run a humidifier next to them if the air is dry.
Flowers Turning Brown
Begonia flowers turn brown as they start to die back, which is totally normal. Pinch out the brown/faded flowers regularly to encourage fresh new blooms.
Leaves Turning Yellow
This is usually caused by overwatering, but in some cases could be due to a fungal disease or lack of light. Ensure the soil is not wet or soggy.
If you suspect disease, prune off the yellow leaves, give your begonia better air circulation (an oscillating fan works great indoors), and never water over the top of the leaves.
Dropping Stems / Leaves
When a begonia starts dropping leaves and stems, it’s usually because of too much water (especially during the winter).
But it could also be from exposure to cold temps, or moving the plant around too much.
Leaves Turning White
White or faded leaves usually happens when they are getting too much direct sun. Move it to a location where it gets bright, indirect light inside, or to a shadier spot outside.
Curling Leaves
This can be caused by a number of problems. First, check to make sure there aren’t any bugs on the leaves. Otherwise, it could be due to lack of humidity, improper watering, or too much sun or heat.
Wilting Or Drooping
Droopy leaves is usually caused by under watering. But it could also happen after the plant has been repotted, if it’s being overwatered, or if it’s getting too hot.
Not Flowering
First off, not all begonias flower, so this may be normal for the variety that you have.
If you have a flowering one, then it could be caused by lack of nutrients, using the wrong type of fertilizer, or not enough light.
Begonia Plant Care FAQs
In this section, I will answer some of the most frequently asked questions about begonia care. If you don’t see yours here, then ask it in the comments below.
Are begonias easy to grow?
Yes, they are easy to grow, as long as you give begonias the right care. They are the most fussy about water and humidity, which can be a struggle to get right for some.
Do begonias like sun or shade?
Most begonias like shade, and will burn in the full sun. However, there are new cultivars that have been bred to grow in the full sun. So it really depends on which variety you have.
Can begonias live inside?
Yes, begonias can live inside, and they make excellent houseplants. The only types you can’t grow indoors year-round are the tuberous ones, because they require a period of winter dormancy.
Do begonias come back every year?
It depends on where you live. Begonias are tender perennials that can survive outside during the winter in the right growing zone. Some are hardier than others though, so it’s important to know the ideal climate for each variety that you have.
Are begonias indoor or outdoor plants?
Begonias can be grown as either indoor or outdoor plants, depending on where you live and the variety that you have.
How do I save begonias for next year?
Bring them indoors for the winter. Begonias can either be grown as houseplants, or you can overwinter the tubers – depending on what type you have.
Growing begonias is easy, and you can enjoy their beauty year round. Plus it’s fun to collect different varieties, and they are all sure to add tons of color to your home and garden. If you follow these begonia plant care tips, they will thrive for years to come.

Flowers brown on edges and do not open
Amy Andrychowicz says
I suspect a watering issue is what’s causing you begonia flower buds to turn brown before they open. Check the soil to make sure it’s not being overwatered, it should be slightly damp, but not wet. I would also inspect the flowers and leaves for bugs, and deadhead the buds that have brown on them.
Michael Hicks says
I overwatered my begonias and the whole stalk fell off. Can I salvage these and if so how?
Amy Andrychowicz says
Uh oh, sorry to hear that your begonias are struggling. It’s difficult to know for sure if they will grow back after the stalk falls off. The best thing you can do is let the soil dry out a bit, and give it time to see if they will recover.
Vicki says
My Begonia bent just above the soil level then broke off the base. I put it in water and it finally produced roots. I’m going to repot it now. Unfortunately my other one just did the same thing. I’ll try to root that one out too.
Linda Palmer says
the greenhouse lady told me to use Epson salt on my begonias. but how much? she said just a little???i am still confused. how much and how often? thanks in advance for ur help
Amy Andrychowicz says
Rather than epsom salts, I recommend using a natural granular fertilizer for flowering plants. See the “Fertilizer” section above for my recommendations.
Deb Bury says
Hi-I just bought a begonia 1 month ago-beautiful pink blooms-but now the edges of the blooms started turning a pastel green- now some of the whole blooms themselves are that pastel green. What am I doing wroing? Is it time to dead head some of the off the plant? thank you for your help.
Amy Andrychowicz says
It’s hard to say for sure. Begonia flowers do tend to change color as they age and begin to fade, which is normal. But it could also be due to improper lighting, or either a pH or nutrient deficiency. I would make sure it’s getting the right amount of light and water, then check the pH of the soil. Once spring comes, you can start feeding regularly with a natural fertilizer for flowering plants.
Anne Leblanc says
My begonia strigillosa is getting brown, dry, crispy leaves faster than I can remove them. I am afraid I am losing both plants (mama and her baby plant). The soil is too damp, I am letting it dry. But I am afraid I am losing the battle. Such a gorgeous plant but now it looks terrible. I wish I could send a picture, it would help you help me!
Thanks,
Anne
Amy Andrychowicz says
It sounds like you’re doing the right thing by letting the soil dry a bit. You could speed that up by sliding the plants out of their pots, and letting them sit bare-root. Also, make sure to check the leaves for signs of bugs, just in cause that is the problem. Brown, dried leaves is one symptom of spider mites.
Mary Ellen Holt says
I got 4 begonias in a large pot for Mother’s Day. They are blooming but they are getting too tall and are bending over. Why? What can be done?
Amy Andrychowicz says
I recommend pruning your leggy begonias to get them back in shape. It’s a bit late in the season for it, but worth it if they are perennials in your area, or you plan to bring them indoors for winter. Pruning is the best way to get them busy and full again, so it’s worth a try.
Sue says
Ive left my begonias out all over the winter normally they come back bu this year looks like they’re not can I dig them out to see if there’s any shoots or will I kill them if I disturb them do they need fresh compost I’m not sure what to do ?
Amy Andrychowicz says
You can certainly dig around your begonias to see if the roots are still alive. If they are tuberous types, then you should see firm, white tubers under the soil. Otherwise, you should see a healthy root system (firm and white roots). If there’s no signs of healthy tubers, or you only find brown/dead roots, then they likely didn’t survive the winter. If you had a colder than normal winter, then that would explain why they didn’t make it this year.
marilyn millar says
I bought a Begonia should I cut the big leaves on top they are turning brown .I have lots of flowers starting to bloom. Is tea good for plants.
Amy Andrychowicz says
Yes, I would prune off the leaves that are brown. However, you might want to figure out what is causing them to turn brown in the first place. Begonias usually prefer a shady location, and too much sun can burn their leaves. So make sure they’re getting the proper sun exposure. Yes, compost tea is great for any type of plant.
Chris says
I have yellow begonia and I am starting to get red/orange on some of the petals. What does that mean?
Amy Andrychowicz says
It may just be the variety of begonia you have. Or, it could be that the flowers turn red/orange as they start to fade. As long as your plant looks healthy, I wouldn’t worry about it.
Gwen says
Do you have any suggestions for how to start begonia bulbs.It is supposed to be a begonia Switzerland.???
Amy Andrychowicz says
Yes, your begonia tubers should have a flatter side and a side that is more pointy, similar to other bulbs. Plant them with the pointy end facing up, about 1″ deep and 1-2″ apart. If you live in a cold climate, it’s best to plant them indoors 4-5 weeks before your last frost date to give them a head start.
Susan says
This information was so helpful I just had to thank you. I’ve never been successful with begonias and now I know why. I have three new plants to try and I’m so excited.
Thanks again?
Amy Andrychowicz says
Awesome, so happy that my guide helped you so much! You’re welcome. Good luck with your new begonias, and have fun!
Val Beavis says
My border begonias have all frizzled up and are dying this year, only out in the front garden the rest are fine, is this because of the hot weather we have had this year, this is the third year I have had them there, The last two years they were great, I got lots of compliments about them, but this year naaaaah not good..can you help at all.
Amy Andrychowicz says
It sounds to me like your begonias were getting too much sun this year. I would double check the sun exposure of that area during the summer to make sure it’s not too sunny for them. Otherwise, make sure they are getting plenty of water during those summer heat waves. They don’t like hot, hot weather, so keeping them well hydrated will help them get through it.
Kezia says
My begonia’s leaves are becoming brownish on the edges, then it withers. I am worried. What could be the reason and how to help her out? please guide me.
Amy Andrychowicz says
Do you know if your begonia is a tuberous variety? If so, then it sounds to me like it’s going dormant, which is totally normal. Here’s how to overwinter tuberous begonias.
Anna Vogel says
My giant begonia leaves are turning a pale reddish pink all of a sudden and then getting holes in the leaves, then dying, turning brown. What should I do? They were doing great for some time now, are planted outside in a flower bed under a tree. Is this a fungus?
Amy Andrychowicz says
It sounds to me like your begonias are starting to go dormant. If you had a cold spell recently, that could have triggered it. Also, if the type you’re growing have tubers (aka bulbs), then they will naturally die back in the fall, and go dormant for the winter. You can lift the tubers and store them indoors, if that is the case. Here’s how… How To Overwinter Tuberous Begonias.
Brendan Douglas says
Hi. My begonias have over growing leafs. Should I have pich them at early stage?? Many thnx
Amy Andrychowicz says
Yes, you can pinch your begonias to keep them growing bushy and fuller.
Dora says
I just read your post on wintering tuberous begonias which was very helpful and answered all my questions! Thanks much!
Amy Andrychowicz says
Awesome, glad you found the post about overwintering them! 🙂
