Understanding the Different Types of Begonias
Before you start digging, it helps to know which begonia you are bringing home. While there are thousands of varieties, most home gardeners choose from four main groups. Each group has its own personality and preferred role in the garden.
Tuberous Begonias
Tuberous begonias are the "glamour" plants of the family. They grow from a potato-like tuber and are famous for their large, spectacular flowers that can reach several inches across. These blooms often resemble roses, camellias, or carnations. They come in both upright and trailing forms, making them the perfect choice for window boxes and hanging baskets where their heavy blossoms can drape beautifully over the edges.
Wax Begonias
Wax begonias are the dependable workhorses of the summer garden. You can identify them by their succulent, waxy leaves, which come in shades of bright green or deep bronze. These plants stay relatively small and compact, usually reaching about 6 to 12 inches in height. Because they are so consistent and bloom non-stop, they are ideal for mass plantings in garden borders or as colorful accents in mixed containers.
Rex Begonias
If you prefer interesting textures and patterns over flowers, Rex begonias are for you. These are grown primarily for their foliage. Their leaves feature swirls, stripes, and splotches in shades of silver, purple, pink, and burgundy. While they do produce small flowers, the real show is the leaves. They are excellent as indoor houseplants or as "thriller" plants in shaded outdoor pots.
Cane-Stemmed and Angel Wing Begonias
These begonias have upright, woody stems that look a bit like bamboo. The most famous variety in this group is the Angel Wing begonia, named for its long, pointed leaves that resemble wings. These plants can grow quite tall and often produce large, drooping clusters of flowers. They are very popular as year-round houseplants but can also spend the summer outdoors in a protected, shady spot.
Key Takeaway: Choose Tuberous begonias for big, showy flowers, Wax begonias for colorful borders, and Rex or Angel Wing varieties for stunning foliage and height.
Right Plant, Right Place: Where to Grow Begonias
The first step toward success is matching your begonias to the conditions in your yard or home. Begonias are tropical plants by nature, which means they enjoy warmth and humidity, but they have very specific needs when it comes to light and soil.
Light Requirements
Most begonias are famous for their ability to grow in the shade. However, "shade" doesn't mean total darkness. In the garden, they prefer "filtered" or "dappled" light—the kind of light that peeks through the leaves of a tall tree.
If you are planting them in a spot that gets some sun, try to make sure it is morning sun. The afternoon sun in many parts of the US is too intense and can scorch the leaves, leaving them with brown, crispy edges. Varieties with bronze foliage are generally a bit tougher and can handle more sun than those with green leaves.
Soil and Drainage
Begonias have delicate root systems that do not like to sit in water. For this reason, drainage is the most important factor in your soil. Drainage simply refers to how fast water leaves the soil after rain or watering.
In garden beds, the soil should be rich in organic matter but loose enough that it doesn't stay soggy. If your soil is heavy clay, consider planting in raised beds or containers instead. For potted begonias, always use a high-quality, all-purpose potting mix. Ensure your pots have plenty of holes in the bottom so excess water can escape easily.
Temperature and Humidity
Because they come from tropical regions, begonias are very sensitive to the cold. They should not be placed outdoors until the danger of frost has passed and nighttime temperatures are consistently above 60°F. If the air is too cold, the plants may stop growing or drop their leaves. They appreciate humidity, which makes them feel right at home in the humid summer air of the East Coast and Midwest.
How to Plant Begonia Tubers
If you are starting with tuberous begonias from Longfield Gardens, you will likely receive them as dormant tubers. These look like small, brown, shaggy discs. Starting them is an exciting process that marks the beginning of the spring season.
Starting Tubers Indoors
In many parts of the country, the growing season isn't quite long enough to get the most out of tuberous begonias if you wait to plant them outside. Starting them indoors about 8 to 12 weeks before the last frost date gives them a head start.
- Find the Indented Side: Look at the tuber closely. One side will be slightly hollowed out or indented. This is the top where the sprouts will emerge. The rounded side is the bottom.
- Prepare the Container: Use a shallow tray or small pots filled with damp potting mix.
- Place the Tubers: Set the tubers onto the soil with the indented side facing up. You do not need to bury them deep; just tuck them into the soil so the tops are barely visible or covered with only a half-inch of soil.
- Water Lightly: Give them just enough water to settle the soil. Avoid overwatering at this stage, as a tuber without roots can rot if it stays too wet.
- Provide Warmth and Light: Place the tray in a warm spot (around 70°F) with bright, indirect light. In a few weeks, you will see pink or green buds starting to sprout.
Transplanting to the Garden
Once the weather is warm and the plants have several leaves, they are ready for the outdoors.
- Spacing: Space your begonias about 8 to 12 inches apart. This gives them enough room to grow without crowding, which helps air circulate around the leaves.
- Depth: When moving a started plant into a larger pot or the ground, plant it at the same depth it was growing in its original container. The base of the stem should be level with the soil surface.
- Handle with Care: Begonia stems and leaves are succulent, which means they are full of water and can snap easily. Handle the plants gently during the move.
What to Do Next: Planting Checklist
- Check the 10-day forecast to ensure nighttime temperatures stay above 60°F.
- Verify that your planting site or container has excellent drainage.
- Ensure the indented side of the tuber is facing up.
- Water the soil immediately after planting to settle the roots.
Essential Care for Begonias
Once your begonias are settled in their new home, they are relatively low-maintenance. They don't require constant attention, but getting the watering and feeding right will result in much larger blooms and healthier foliage.
Watering Correctly
The goal with begonias is to keep the soil "evenly moist." This means the soil should feel like a wrung-out sponge. It shouldn't be dripping wet, and it shouldn't be bone-dry.
The best way to tell if it is time to water is to use your finger. Stick it about an inch into the soil. If it feels dry, it is time to water. If it still feels damp, wait another day or two. When you do water, try to aim for the base of the plant. Getting water on the leaves can sometimes lead to fungal issues like powdery mildew, especially if the air is very humid.
Feeding Your Plants
Begonias are heavy feeders, especially the tuberous and Rex varieties. They need a consistent supply of nutrients to keep producing those big flowers and colorful leaves.
For the easiest results, you can mix a slow-release granular fertilizer into the soil at planting time. Alternatively, you can use a water-soluble liquid fertilizer once a month throughout the summer. Look for a "balanced" fertilizer (like a 10-10-10) or one formulated for flowering plants. Always follow the instructions on the package for the correct amount to use. For more care details, see our Begonia Care and Propagation guide.
Grooming and Pruning
Begonias are generally "self-cleaning," which means the old flowers will fall off on their own as they fade. You don't necessarily have to "deadhead" them (remove spent blooms) to keep them flowering, but removing wilted flowers can keep the plant looking tidy.
If your begonias start to look a bit "leggy"—meaning the stems are getting very long with few leaves at the bottom—you can pinch them back. Simply use your thumb and forefinger to snip off the top inch of the stem. This encourages the plant to grow more side branches, resulting in a fuller, bushier shape.
Key Takeaway: Consistent moisture and monthly feeding are the "secrets" to begonias that look great all summer. If they get too tall, a quick pinch will help them fill out.
Growing Begonias in Containers
Begonias are perhaps the best container plants for shade. They don't mind being a little crowded, and their shallow roots mean they can thrive in pots of almost any size.
Choosing the Right Pot
While begonias can grow in plastic or ceramic, many gardeners prefer terra cotta or clay pots. Clay is porous, which means it allows air and moisture to move through the sides of the pot. This helps prevent the soil from staying too wet, which is a common cause of begonia trouble. Whatever material you choose, the pot must have drainage holes.
Potting Mix Tips
Never use "garden soil" or "topsoil" in a container. It is too heavy and will pack down, preventing the roots from breathing. A high-quality potting mix that contains peat moss, perlite, or vermiculite is perfect for begonias. These materials help the soil hold onto just enough moisture while allowing the rest to drain away.
Companion Plants
Begonias look wonderful on their own, but they also play well with other shade-loving plants. Try pairing them with:
- Coleus: Known for its vibrant foliage that matches many Rex begonia colors.
- Ferns: The delicate texture of ferns provides a beautiful contrast to the bold leaves of begonias.
- Fuchsia: A great partner for trailing begonias in hanging baskets.
- Caladiums: These offer large, heart-shaped leaves that complement the smaller flowers of wax begonias.

Seasonal Transitions: Overwintering Your Begonias
In most of the United States, begonias are treated as annuals, meaning they finish their life cycle when the frost arrives. However, because they are perennials in tropical climates, you can save them to grow again next year.
Saving Tuberous Begonias
As autumn approaches and temperatures drop, tuberous begonias will naturally start to turn yellow and die back. This is a signal that the plant is moving its energy into the tuber for the winter.
- Reduce Water: Stop watering once the leaves start to yellow.
- Lift the Tubers: After the first light frost kills the top of the plant, carefully dig the tubers out of the soil.
- Clean and Dry: Shake off the excess soil and let the tubers dry in a cool, shady spot for a few days.
- Storage: Place the dry tubers in a paper bag filled with peat moss or sawdust. Store them in a cool, dark, and dry place (like a basement or crawlspace) where temperatures stay around 40–50°F.
- Replant: In the spring, take them out and start the process all over again!
Bringing Houseplants Indoors
Rex and Angel Wing begonias can be brought inside to live as houseplants for the winter. Before the nighttime temperatures drop below 50°F, move your pots indoors. Place them in a bright window but keep them away from cold drafts or dry heat vents. They may lose a few leaves as they adjust to the lower humidity of your home, but they will soon settle in. If you want another indoor-care perspective, see Growing Angel Wing Begonias.
Staying Safe in the Garden
It is important to remember that begonias, while beautiful, contain certain compounds that can be irritating. The underground parts of the plant, such as the tubers and rhizomes, contain calcium oxalate crystals.
If you have curious pets or small children, it is best to plant begonias in containers that are out of reach or in garden beds where they won't be nibbled on. Ingestion can cause irritation to the mouth and throat. Always wash your hands after handling the plants or wear gardening gloves to avoid any minor skin irritation.
Troubleshooting Common Begonia Issues
Even though we aim for a perfect season, gardening always involves a little bit of observation and adjustment. If your begonias aren't looking their best, the fix is usually very simple.
Yellowing Leaves
If the leaves are turning yellow and the stems feel soft or mushy, the plant is likely getting too much water. Check the drainage of your pot and allow the top inch of soil to dry out before you water again.
Brown, Crispy Edges
This is usually a sign of "leaf scorch." It happens when the plant gets too much direct afternoon sun or if the air is extremely dry. Move your pot to a shadier spot or ensure the soil is staying consistently moist during heatwaves.
Powdery Mildew
This looks like a dusting of white flour on the leaves. It happens when there is high humidity and not enough air movement. To prevent this, space your plants a bit further apart and try to keep the leaves dry when you water. If it persists, you can find simple organic sprays at your local garden center.
Dropping Flowers
If your begonia is dropping its buds before they open, it might be stressed by a sudden change in temperature or uneven watering. Try to keep the environment as consistent as possible, and the plant will usually recover on its own.
FAQ
Do begonias need a lot of sun?
Most begonias prefer partial to full shade. They thrive in bright, indirect light or filtered morning sun. Too much direct afternoon sun can burn their leaves, though wax begonias with bronze foliage can tolerate more sun than other varieties.
How often should I water my begonias?
You should water begonias whenever the top inch of soil feels dry to the touch. The goal is to keep the soil consistently moist but never waterlogged. Containers usually need more frequent watering than garden beds, especially during hot summer days.
Can I grow begonias indoors?
Yes, many types of begonias make excellent houseplants. Rex begonias and Angel Wing begonias are particularly popular for indoor growing because of their beautiful foliage. They need bright light and a bit of extra humidity to look their best inside.
Do I need to remove old flowers from my begonias?
Most modern begonia varieties are "self-cleaning," meaning the old flowers fall off by themselves. However, removing spent blooms and any yellowing leaves can help keep the plant looking tidy and may prevent fungal issues in humid weather.
Conclusion
Begonias are a wonderful addition to any home or landscape, bringing unmatched color and texture to the shaded parts of our lives. By choosing the right variety for your needs—whether it’s the massive blooms of a tuberous begonia or the striking patterns of a Rex—you can create a professional-looking display with very little effort.
