Introduction
The first time you see a begonia in full bloom or marvel at its swirling, colorful leaves, it is hard not to fall in love. Whether it is the massive, rose-like flowers of a tuberous begonia or the neon-bright patterns of a Rex begonia, these plants have a way of stealing the spotlight. Many gardeners enjoy them in patio pots or hanging baskets throughout the summer, but as the weather cools, a common question arises: will begonias survive indoors?
The wonderful news is that begonias are tropical plants by nature, which means they are perfectly suited for life inside your home. At Longfield Gardens, we want to help you transition these beautiful plants from the garden to your living room with ease. While some types of begonias thrive as year-round houseplants, others prefer a short winter nap before returning to the garden in spring. If you are looking for more ways to use them outdoors too, the Upright Double Begonias collection is a great place to compare varieties.
This guide will help you identify which type of begonia you have and provide the simple steps needed to keep it healthy indoors. Whether you are a beginner or a seasoned gardener, you will find that caring for begonias inside is a rewarding way to keep your home bright and cheerful all year long. With just a few basic adjustments to light and water, your begonias can continue to be a source of joy well beyond the summer season.

Understanding Your Begonia Type
Before you bring a plant inside, it helps to know which group it belongs to. Not all begonias behave the same way once they move indoors. Identifying your plant is the first step toward giving it exactly what it needs to flourish. Most begonias fall into three main categories that work well in a home environment.
Rex and Rhizomatous Begonias
These are often called "foliage begonias." They are prized for their spectacular leaves rather than their flowers. You might see patterns of silver, purple, pink, and deep green in swirls or metallic finishes. These begonias grow from a thick, fleshy stem called a rhizome that sits right at the soil surface. Because they naturally grow on forest floors in the shade, they are some of the best varieties to grow as permanent houseplants.

Cane-Stemmed Begonias
You may know these by the popular name "Angel Wing" begonias. They have long, upright stems that look a bit like bamboo, with swollen joints or "nodes." Their leaves are often shaped like wings and may have beautiful silver spots. These begonias are very sturdy and can grow quite large indoors. They often produce clusters of drooping flowers in shades of pink, red, or white. For a closer look at size and shape, see How High Do Begonias Grow?.
Tuberous Begonias
These are the showstoppers you likely planted in your garden beds or hanging baskets for their massive, colorful blooms. Varieties like "Non-Stop" or "Illumination" begonias belong to this group. Unlike the other types, tuberous begonias grow from a brown, potato-like bulb called a tuber. These plants usually want to go dormant in the winter. While they can stay indoors, they will "sleep" through the coldest months rather than continue growing. You can browse the Upright Double Begonias collection to compare flower forms and colors.
Key Takeaway: Identify if your begonia is grown for its leaves (Rex), its upright stems (Cane), or its large garden flowers (Tuberous). This tells you if the plant will stay green all winter or if it needs a rest.
Creating the Best Indoor Environment
Once you bring your begonia inside, the goal is to mimic the warm, tropical environment it loves. You do not need a professional greenhouse to make this happen. Most begonias are happy in the same temperatures that humans enjoy. However, a few small tweaks to your "indoor climate" will make a big difference.

Finding the Right Light
In the garden, begonias usually love the shade. Indoors, "shade" is often too dark for them to stay healthy. The best spot for an indoor begonia is a place with bright, indirect light. This means the plant should be in a very bright room, but the sun’s rays should not hit the leaves directly. A Rex begonia is especially well suited to that kind of filtered light.
Direct afternoon sun can be too hot and may scorch the delicate foliage. An east-facing or west-facing window is often perfect. If you only have a very sunny south-facing window, you can soften the light with a sheer curtain. If the stems of your begonia start to look "leggy" or stretched out, it is usually a sign that the plant is reaching for more light.
Managing Temperature and Drafts
Begonias are sensitive to extreme temperature changes. They prefer temperatures between 65°F and 75°F during the day and slightly cooler at night. The most important thing is to keep them away from "drafty" spots. This includes cold air from windows in the winter or hot, dry air from heating vents and radiators. A steady, moderate temperature helps the plant stay relaxed and productive.
What to Do Next
- Pick a bright spot near a window where you can easily see the plant.
- Check for nearby heater vents and move the plant if it is in the direct path of hot air.
- Observe the leaves for a week; if they look washed out, move the plant slightly further from the light.
Mastering the Art of Watering
Watering is the most important part of indoor begonia care, but it is also where many gardeners get a bit nervous. At Longfield Gardens, we believe in a "deep water and dry out" approach. This is much better for the plant than giving it tiny sips of water every day.
The Finger Test
The best way to know if your begonia needs water is to use your finger. Stick it about an inch into the soil. If the soil feels damp, wait a few more days. If the top inch of soil feels dry to the touch, it is time to water.
Why Drainage Matters
"Drainage" simply means how fast water leaves the soil. Begonias have very delicate roots that can rot if they sit in puddles of water for too long. Always make sure your begonia is in a pot with holes in the bottom. When you water, pour enough so that it runs out of the holes. This flushes out any salt buildup and ensures the roots at the bottom of the pot get a drink. After about 20 minutes, empty any water that has collected in the saucer beneath the pot.
Adjusting for the Seasons
Plants grow more slowly in the winter because the days are shorter. This means they "drink" less water. You will likely find yourself watering your begonias less often in January than you did in July. Always let the plant tell you when it is thirsty rather than following a strict calendar schedule.
Key Takeaway: Water your begonia only when the top inch of soil feels dry. Always use a pot with drainage holes and never let the plant sit in standing water.
Humidity: The Secret to Healthy Leaves
One of the biggest challenges for begonias indoors is dry air. Most homes become very dry in the winter when the furnace is running. Begonias come from humid tropical regions, and they love moisture in the air. If the air is too dry, you might notice the edges of the leaves turning brown and "crispy."
The Pebble Tray Solution
A great way to boost humidity without making your whole house feel damp is to use a pebble tray. Fill a shallow tray or saucer with small stones or pebbles. Add water to the tray, but keep the water level just below the top of the stones. Set your begonia pot on top of the stones. As the water evaporates, it creates a little "cloud" of humidity right around the plant’s leaves. Just make sure the bottom of the pot is not actually sitting in the water.
Why Misting Isn't the Answer
You might be tempted to use a spray bottle to mist your begonia leaves. While this seems helpful, it can actually cause problems. Wet leaves are more likely to develop mildew or fungal issues indoors where there is less air movement. It is much better to provide "ambient" humidity through a pebble tray or by grouping several plants together, which naturally releases moisture into the air.
Improving Airflow
While begonias like humidity, they do not like stagnant, "heavy" air. If your plants are packed too tightly together, they might struggle. Giving each plant a little "breathing room" ensures that air can circulate around the leaves, which keeps the plant dry and healthy.
Bringing Garden Begonias Inside for Winter
If you have begonias growing in outdoor containers, you can certainly bring them inside to protect them from the frost. This is called "overwintering." Depending on the type of begonia, you will treat them in one of two ways. If you are wondering how light affects them outdoors, the guide How Much Sun Does a Begonia Plant Need? is also helpful.
Bringing in Wax and Cane Begonias
Small wax begonias (the ones often used in bedding) and tall Angel Wing begonias can be brought inside and treated like houseplants.
- Check for guests: Before bringing them in, look under the leaves and in the soil for any insects. A gentle spray with a garden hose can help wash away any lingering bugs.
- Prune back: You can trim the plant back by about a third. This makes it easier to manage indoors and encourages the plant to grow new, healthy leaves that are adapted to lower light levels.
- Expect a transition: It is normal for a plant to drop a few leaves when it first moves inside. It is just adjusting to the new environment. Be patient and keep the care consistent.
Overwintering Tuberous Begonias
Tuberous begonias (like those from the Longfield Gardens collection) naturally want to rest during the winter. As the nights get cooler and the days get shorter, you will notice the leaves starting to turn yellow. This is a sign the plant is moving its energy down into the tuber. For broader planting advice, see How Deep Should I Plant Begonias?.
- Stop watering: When the foliage begins to die back, stop watering the plant.
- Let it dry out: Once the stems have completely withered, you can cut them off near the soil line.
- Store the tubers: You can leave the tubers in their pots (if the soil is bone-dry) or dig them up and store them in a cool, dark, dry place like a basement or closet.
- Wake them up: In the early spring (usually March or April), you can bring the tubers back into the light, start watering again, and watch the new sprouts emerge.
Key Takeaway: Most garden begonias can come inside for winter. Some will stay green and grow, while tuberous types will go dormant and need to be kept dry until spring.
Potting, Soil, and Fertilizer
Keeping your indoor begonia healthy also involves the right "housing" and "food." Because begonias have relatively small and shallow root systems, they do not need massive pots. In fact, they often do better when their roots are a little bit snug.
Choosing the Right Soil
Begonias need soil that is light and "fluffy." Avoid using regular garden soil from your backyard, as it is too heavy and will pack down tightly in a pot, suffocating the roots. Instead, use a high-quality "potting mix" designed for indoor plants. These mixes usually contain peat moss or coco coir and perlite (those little white "popcorn" bits) to help with drainage and airflow.
When and How to Feed
Your begonia will benefit from a little extra nutrition during the growing season (spring through early autumn). Use a balanced, water-soluble fertilizer formulated for houseplants. We recommend diluting the fertilizer to half-strength. It is much better to give the plant a weak "snack" regularly than a heavy "feast" all at once.
During the winter months, when the plant is growing very slowly or is dormant, you should stop fertilizing entirely. The plant is resting and does not need the extra nutrients until the days get longer in the spring.
Grooming Your Plant
To keep your indoor begonia looking its best, do a little bit of "housekeeping" every few weeks.
- Deadhead: Remove any faded or dried-up flowers. This encourages the plant to put its energy into new growth.
- Remove yellow leaves: If a leaf looks old or yellow, snip it off at the base. This keeps the plant tidy and prevents any potential mold from starting on decaying foliage.
- Rotate the pot: Every time you water, give the pot a quarter-turn. This ensures all sides of the plant get equal light and prevents the begonia from leaning toward the window.
Common Signs of a Happy Begonia
When your begonia is thriving indoors, it will tell you! Learning to read the plant’s signals helps you feel more confident as a gardener. A happy begonia will have firm, vibrant leaves. Depending on the variety, it may produce clusters of delicate flowers even in the middle of winter.
If you see new, tiny leaves unfurling at the center of the plant, you know you have found the "sweet spot" for light and water. If the plant stays upright and the colors of the leaves are bright and distinct, you are doing a great job.
On the other hand, if the plant looks a little "sad," do not worry. Usually, a small change is all it takes to fix things.
- Leaning stems: The plant needs more light.
- Drooping leaves: This could mean the soil is too dry or too wet. Check the soil with your finger to be sure.
- Crispy edges: The air is likely too dry. Try a pebble tray.
By observing your plant and making these simple adjustments, you will find that begonias are actually quite resilient and forgiving. They want to grow, and with your help, they will.
Growing New Begonias from Cuttings
One of the most exciting things about keeping begonias indoors is how easy they are to propagate. "Propagation" is just a fancy word for growing a new plant from a piece of an old one. Many begonias, especially Rex and Cane types, are famous for being easy to "clone."
Water Rooting for Cane Begonias
If you have an Angel Wing begonia that is getting too tall, you can trim the top off and grow a whole new plant!
- Take a cutting: Cut a stem that is about 4 to 6 inches long, making the cut just below a "node" (the bump where a leaf attaches).
- Remove lower leaves: Take off the bottom couple of leaves so you have a bare stem.
- Place in water: Put the stem in a glass of clean water. Make sure no leaves are touching the water.
- Wait for roots: Place the glass in a bright spot. Within a few weeks, you will see little white roots growing from the stem. Once the roots are about an inch long, you can plant your new begonia in a pot with soil.
Leaf Cuttings for Rex Begonias
Rex begonias can actually grow new plants from just a single leaf. It feels a bit like magic! You can simply place a leaf stem in water, or even cut a leaf into sections and press them into damp soil. This is a fun project to do with children or as a way to share your favorite plants with friends.
Key Takeaway: Begonias are very easy to multiply. Trimming your plant can actually give you "free" new plants to enjoy or give away.

FAQ
Can I bring my outdoor "Non-Stop" begonias inside for the winter?
Yes, but they will likely want to go dormant. Tuberous begonias like the "Non-Stop" variety usually stop blooming and lose their leaves in the winter. Instead of keeping them as active houseplants, it is best to let the foliage die back, store the tubers in a cool, dry place, and replant them in the spring for another season of garden color.
Do begonias need direct sunlight when they are inside?
No, most begonias prefer bright, indirect light. Direct sunlight—especially through a window which can magnify heat—can scorch their leaves and cause them to turn brown or fade. A spot near a bright window with a sheer curtain or an east-facing window that gets gentle morning sun is usually the best choice for indoor success.
Why are the edges of my begonia leaves turning brown and crunchy?
This is usually caused by low humidity. Indoor air, especially during the winter heating season, is often much drier than the tropical environments begonias prefer. You can fix this by placing your plant on a pebble tray filled with water or by grouping it with other plants to create a small pocket of moisture in the air.
How often should I water my begonia once it is indoors?
There is no set schedule, as watering depends on the light and temperature in your home. Instead of a calendar, use your finger to check the soil. Water the plant thoroughly only when the top inch of soil feels dry. Remember to always empty the drainage saucer so the roots are not sitting in water, which can lead to rot.
