Introduction
Begonias are some of the most versatile and rewarding plants you can add to your garden, but their beauty does not have to be limited to the porch or patio. Many gardeners are surprised to learn that these tropical favorites are actually quite happy to live inside your home. Whether you are captivated by the shimmering, metallic patterns of foliage begonias or the delicate, cascading blooms of flowering varieties, growing them indoors is a wonderful way to enjoy their charm all year long. At Longfield Gardens, we enjoy testing how different varieties perform both in the ground and in containers, and many of our favorites transition seamlessly to indoor life. If you are ready to shop, start with our begonia collection or browse spring-planted bulbs for more options.
This guide is designed for anyone who wants to bring that lush, tropical feeling inside. We will cover which types thrive best in a home environment and how to provide the simple care they need to flourish. For a broader overview of planting and care, see our begonia care guide.
While begonias have a reputation for being slightly particular, they are actually very communicative plants. Once you learn to read their signals, you will find that they are much easier to care for than many common houseplants. Our goal is to help you feel confident as you welcome these stunning plants into your living space.
Growing begonias indoors is an achievable and rewarding project for any plant lover. With a few basic adjustments to lighting and humidity, you can create a vibrant indoor oasis. If you want to match plants to your home’s light conditions, our sun or shade guide for begonias is a helpful next step.
Choosing the Right Begonia for Your Home
The first step to success is choosing a variety that fits your indoor environment. There are thousands of begonia species, but they are generally grouped into a few main categories based on their root systems and growth habits. Understanding these groups makes it much easier to provide the right care.
Rex Begonias
Rex begonias are the undisputed kings of the foliage world. They are grown specifically for their large, asymmetrical leaves that come in a dizzying array of colors, including silver, purple, pink, and deep burgundy. These plants grow from rhizomes—thick, fleshy stems that creep along the soil surface. Because they naturally grow on the forest floor in tropical regions, they are well-suited for the lower light levels found in most homes.
Cane-Stemmed Begonias
Commonly known as "Angel Wing" begonias because of their wing-shaped leaves, these are some of the toughest varieties for indoor growing. They feature tall, bamboo-like stems and often have beautiful silver spotting on their foliage. Many cane begonias also produce heavy clusters of pendulous flowers in shades of pink, red, or white. They are upright growers and can become impressive floor plants over time.
Rhizomatous Begonias
Similar to Rex types, these begonias grow from a thick horizontal stem (the rhizome). However, they are often a bit more resilient and less prone to leaf edges drying out. They offer incredible textures, from fuzzy, felt-like leaves to "eyelash" begonias with tiny hairs along the leaf margins. They are compact and look lovely on side tables or desks.
Tuberous Begonias
These are the showstoppers of the summer garden, known for their massive, rose-like blooms. While they are usually grown outdoors, you can explore tuberous types like our Non Stop begonias or the Begonia Non Stop Mix if you want plenty of color. They can be kept in a sunny window during their blooming season. It is important to remember that tuberous begonias require a dormancy period in the winter. Unlike the evergreen Rex or Cane types, these will naturally die back in the fall, and the tubers must be stored in a cool, dry place until spring.
Key Takeaway: For a beginner looking for a year-round houseplant, Cane-stemmed and Rhizomatous begonias are the easiest to manage. If you want high-impact color and pattern, Rex begonias are the best choice.
Light Requirements for Indoor Success
Getting the light right is the most important factor when you grow begonias indoors. In their native habitats, most begonias live under the canopy of larger trees. This means they love light, but they do not want the harsh, direct rays of the sun to hit their leaves.
The ideal spot for most indoor begonias is near an east-facing or west-facing window. An east window provides gentle morning sun, which is perfect for encouraging blooms on flowering types without scorching the foliage. If you only have a south-facing window, which tends to be very bright and hot, move the plant a few feet back from the glass or use a sheer curtain to filter the light.
If you notice your begonia is becoming "leggy"—meaning the stems are stretching out with large gaps between the leaves—it is likely asking for more light. Conversely, if the leaves start to look bleached or develop brown, crispy spots, it may be getting too much direct sun.
For homes with limited natural light, begonias respond very well to LED grow lights. Placing your plants under a light for 10–12 hours a day can keep them lush and vibrant even in the middle of winter. If you want more help matching begonias to brighter or shadier spaces, our begonia light guide is worth a look.
Watering with Confidence
Watering is the area where most gardeners feel a bit nervous, but the rule for begonias is simple: keep them moist, but never soggy. Most begonias have fleshy stems that store a bit of water, which makes them somewhat forgiving, but they do not like to sit in a saucer of water.
The best way to tell if your plant needs water is the finger test. Insert your finger into the top inch of soil; if it feels dry, it is time to water. If it still feels damp, wait a day or two. When you do water, apply it directly to the soil and avoid getting water on the leaves, as this can encourage fungal issues.
During the winter months, when the plant's growth slows down and the air is cooler, you can allow the soil to dry out a bit more between waterings. Always use a pot with drainage holes so that excess water can escape freely.
- Water deep: When you water, do so until it runs out of the bottom of the pot.
- Drain well: Never let the pot sit in a tray of standing water for more than 15 minutes.
- Check often: Smaller pots dry out faster than larger ones, so check your plants at least twice a week.
Creating the Perfect Humidity
Begonias love humidity. Most homes, especially during the winter when the heat is on, have very dry air. This can lead to the edges of the begonia leaves turning brown and crispy. However, you should avoid the common "internet hack" of misting the leaves with a spray bottle. Misting only raises the humidity for a few minutes and can leave the foliage vulnerable to powdery mildew.
Instead, try one of these simple, effective methods to boost humidity:
- The Pebble Tray: Fill a shallow tray with pebbles and add water until it is just below the top of the stones. Set your begonia pot on top of the pebbles. As the water evaporates, it creates a humid microclimate right around the plant.
- Grouping Plants: Plants naturally release moisture through their leaves. By grouping several begonias or other houseplants together, you create a collective pocket of higher humidity.
- Humidifiers: If you have a large collection, a small room humidifier is the most reliable way to keep your plants happy during the dry winter months.
Next Steps for Success:
- Choose a spot with bright, indirect light (like an East window).
- Buy or find a shallow tray and some decorative pebbles.
- Check the soil moisture every few days to establish a routine.
Soil and Fertilizer Basics
Because begonias are sensitive to overwatering, they need a soil mix that drains quickly while still holding a little bit of moisture. A high-quality, peat-based potting soil mixed with a bit of perlite or vermiculite works beautifully. This ensures that the roots have plenty of access to oxygen.
When it comes to feeding your plants, begonias are moderate eaters. During the active growing season (spring through early autumn), you can use a balanced, water-soluble fertilizer. We recommend diluting the fertilizer to half the strength suggested on the label and applying it once a month. This "weakly, weekly" approach—or in this case, a light monthly touch—prevents salt buildup in the soil and provides a steady supply of nutrients.
In the winter, when the plant is resting, stop fertilizing entirely. Resumed feeding in the spring when you see new leaves beginning to unfurl.
Temperature and Airflow
Begonias are comfortable at the same temperatures that humans are. They generally thrive in temperatures between 65°F and 75°F. They can tolerate slightly cooler nights, but they are very sensitive to frost and cold drafts. Keep your plants away from drafty windows, air conditioning vents, and space heaters.
Good airflow is also vital. While they love humidity, stagnant air can lead to fungal problems like powdery mildew. You don't need a gale-force wind, but a gentle movement of air in the room will keep the foliage dry and healthy. If your plants are packed very tightly together, give them a little breathing room to ensure air can circulate around each stem.
Potting and Repotting Your Begonias
Begonias actually prefer to be a little bit snug in their pots. If you put a small begonia in a very large pot, the excess soil will stay wet for too long, which can lead to root issues. Only move your plant up to a larger container when you see roots beginning to grow out of the drainage holes or if the plant needs to be watered every single day to stay hydrated.
When you do repot, choose a container that is only one size larger than the current one (for example, moving from a 4-inch pot to a 6-inch pot). Spring is the best time for this task, as the plant is entering its most vigorous growth phase and will recover quickly.
- Select the pot: Ensure it has at least one large drainage hole.
- Prepare the plant: Gently tip the plant out of its old pot, supporting the base of the stems.
- Loosen the roots: If the roots are circling the bottom, gently tease them outward.
- Add soil: Place some fresh mix in the bottom of the new pot, set the plant in, and fill around the sides.
- Water in: Give the plant a good drink to help the soil settle around the roots.
Bringing Outdoor Begonias Inside for Winter
Many of the begonias we ship at Longfield Gardens are grown as outdoor annuals in colder climates. However, if you have a favorite plant in a container, you can certainly bring it inside to overwinter. The key to this transition is acclimation. For shipment timing and zone details, check our shipping information and hardiness zone map.
Plants experience shock when they move from the high-light, high-humidity environment of the outdoors to the lower-light, drier conditions of a house. About two weeks before the first frost is expected, move your pots to a shadier spot on your porch or under a tree. This helps the plant get used to lower light levels.
Before bringing them through the door, give the plants a thorough inspection. Check the undersides of the leaves and the soil for any hitchhiking insects. A gentle spray with a garden hose can help wash away dust and any lingering pests. Once inside, place them in your brightest window and expect a few leaves to drop as the plant adjusts. This is a normal part of the process, and new leaves adapted to the indoor light will soon take their place.
Simple Pruning and Maintenance
To keep your indoor begonias looking their best, a little bit of grooming goes a long way. Begonias can sometimes become "leggy" or tall and sparse. To encourage a bushier, more compact shape, you can simply pinch off the growing tips of the stems. This signals the plant to grow more side branches.
You should also remove any "spent" flowers or yellowing leaves. This is called deadheading. It keeps the plant looking tidy and prevents old blooms from falling onto the leaves and causing rot. Using a clean pair of snips or just your fingers, remove the old growth back to the main stem.
Growing New Plants from Cuttings
One of the most enjoyable things about growing begonias indoors is how easy they are to propagate. If you have a friend with a beautiful plant, or if you want to make more of your own, you can easily grow a new begonia from a leaf or stem cutting.
For Cane-stemmed begonias, take a stem cutting that is about 4 inches long and has at least two nodes (the bumps where leaves grow). Remove the bottom leaves and place the stem in a jar of clean water or a small pot of moist perlite. In a few weeks, you will see white roots appearing.
For Rex and Rhizomatous begonias, you can actually grow a whole new plant from a single leaf. Cut a healthy leaf with its stem attached and tuck the stem into moist soil. Alternatively, you can lay a leaf flat on top of the soil and make small nicks in the main leaf veins. If you keep the soil moist and the humidity high (covering it with a clear plastic bag helps), tiny new plantlets will begin to grow from those nicks. It feels like magic, but it is just the amazing resilience of the begonia!
Troubleshooting Common Issues
Even with the best care, you might run into a few hurdles. The key is to act quickly and keep the solutions simple.
Yellowing Leaves
If the lower leaves are turning yellow and falling off, the most common cause is overwatering. Check the soil; if it feels very wet, let it dry out completely before watering again. If the soil is dry and the leaves are yellowing, the plant might be hungry for a bit of fertilizer or more light.
Brown Leaf Edges
This is almost always a sign of low humidity. Move the plant away from any heat vents and set up a pebble tray. If the brown spots are only on the side of the plant facing a window, it might be getting a bit of sunburn from direct rays.
Powdery Mildew
This looks like a dusting of white flour on the leaves. It usually happens when the air is damp and stagnant. To fix it, increase the airflow in the room and make sure you aren't getting water on the leaves when you water the plant. You can remove the affected leaves to prevent the fungus from spreading.
Pests
Indoors, begonias can occasionally attract mealybugs (which look like tiny bits of white cotton) or spider mites (which create very fine webbing). If you see these, you can usually take care of the problem by wiping the leaves with a cotton swab dipped in rubbing alcohol or using a gentle insecticidal soap.
Key Takeaway: Most begonia problems are caused by "too much" rather than "too little." Too much water, too much direct sun, or too much fertilizer. When in doubt, scale back and observe how the plant responds.

FAQ
Can I grow outdoor "wax" begonias as houseplants?
Yes, wax begonias are actually very resilient indoors. If you have them in your garden beds, you can dig them up before the first frost, pot them in fresh soil, and bring them inside. They prefer a very bright window and will often continue to produce their small, cheerful flowers all winter long if they get enough light. If you need help getting started with a new plant, our begonia care guide covers the basics.
Why is my begonia dropping its leaves after I brought it inside?
This is a common reaction to the change in environment. The plant is shedding leaves that were adapted to the bright, humid outdoors and will soon grow new ones that are better suited to your home's light and humidity. Ensure it has plenty of indirect light and keep the soil consistently moist (but not wet) during this transition.
Do indoor begonias need to be repotted often?
No, begonias actually prefer to be slightly root-bound. You usually only need to repot them every two to three years, or when you notice the roots are tightly filling the pot and the plant needs water much more frequently than usual. When you do repot, only go up one pot size to prevent the soil from staying too wet. For order timing and coverage by region, review our shipping information and hardiness zone map.
How do I make my indoor begonia bloom?
Flowering begonias, like the Cane-stemmed varieties, need sufficient light to produce blossoms. If your plant looks healthy but isn't blooming, try moving it to a slightly brighter location, such as an east-facing window. You can also use a fertilizer with a slightly higher phosphorus content during the spring and summer to encourage flower production.
