Introduction
Few plants offer the same level of versatile, season-long color as the begonia. Whether you are looking to brighten up a dark corner of your porch or add texture to a garden bed, these plants are up to the task. At Longfield Gardens, we enjoy how begonias provide a lush, tropical feel without requiring expert-level maintenance. They are the perfect solution for gardeners who want high-impact beauty with a straightforward care routine.
In this guide, we will explore exactly where begonias like to be planted to ensure they thrive from spring through the first frost. If you’re ready to shop, start with our Begonia Flower Bulbs for Sale collection. We will cover light requirements, soil preferences, and the best locations for different varieties. This information is designed for home gardeners of all skill levels who want to get the most out of these stunning plants. Success with begonias begins with matching the specific variety to the unique conditions of your yard or home.
Matching Light to Variety
The most common question about begonias is whether they prefer sun or shade. The answer depends almost entirely on the type of begonia you are growing. While most begonias are famous for their ability to thrive in the shade, some modern varieties are bred to handle more light. For a deeper breakdown of light needs, see our begonia sun or shade guide.
Tuberous Begonias
Tuberous begonias are the stars of the shade garden. They produce large, dramatic flowers that can look like roses or camellias. These begonias like to be planted in areas with filtered light or dappled shade. Direct afternoon sun is usually too intense for them and can scorch their tender leaves and petals.
A spot under a leafy tree or a covered patio is often the perfect location. If you see the edges of the leaves turning brown and crispy, the plant is likely getting too much direct light. Conversely, if the plant becomes "leggy" (stretched out with few flowers), it may need a bit more brightness.
Wax Begonias
Wax begonias, often called bedding begonias, are much more flexible. They have thick, waxy leaves that help them retain moisture and withstand more sun than their tuberous cousins. If you have a spot that gets morning sun and afternoon shade, wax begonias will likely flourish there.
Interestingly, the leaf color of a wax begonia can tell you how much sun it can handle. Varieties with bronze or dark-colored foliage typically tolerate direct sun better than those with bright green leaves. In cooler northern climates, these begonias can often handle full sun if they receive enough water.
Rex and Foliage Begonias
Rex begonias are grown primarily for their incredible leaf patterns and colors. Because they are often used as houseplants or tucked into shaded garden beds, they prefer "bright indirect light." This means a spot that is well-lit but never touched by the harsh rays of the sun. Think of the light found in a bright room but away from the window glass, or the shade on the north side of a building.
Key Takeaway: Always check the foliage of your begonia. Thick, dark leaves generally handle more sun, while thin, patterned, or pale leaves require deep or filtered shade.
Begonias
The Importance of Soil and Drainage
Once you have identified a spot with the right light, you must look at the soil. Begonias have relatively shallow root systems and are very sensitive to "wet feet." This is a common gardening term that means the roots are sitting in water that cannot escape.
What is Well-Draining Soil?
Begonias like to be planted in soil that is rich in organic matter but stays loose. "Drainage" refers to how fast water leaves the soil. If you pour water onto the ground and it sits in a puddle for several minutes, the drainage is poor. This can lead to root rot, which is one of the few ways a begonia can fail.
To improve your garden soil, we recommend mixing in compost or finely shredded bark. These materials create tiny air pockets in the soil. These pockets allow water to move through and give the roots space to breathe.
Soil for Containers
If you are planting in pots or hanging baskets, avoid using standard garden soil from the ground. Ground soil is too heavy and compacts easily in a container, which suffocates begonia roots. Instead, use a high-quality potting mix. Most potting mixes are "soilless," consisting of peat moss, perlite, or coconut coir, which provides the airy environment begonias love. For a step-by-step walkthrough, read our how to plant begonias in containers guide.
Moisture Consistency
While begonias do not like to sit in water, they also do not like to dry out completely. The goal is "evenly moist." A good rule of thumb is to stick your finger about an inch into the soil. If it feels dry, it is time to water. If it still feels damp, wait another day.
What to do next:
- Test your soil drainage by digging a small hole and filling it with water.
- If the water takes more than an hour to disappear, add compost to the area.
- Select a potting mix that feels light and fluffy for all container plantings.
Temperature and Airflow Requirements
Because begonias have tropical origins, they are very sensitive to temperature. They are not frost-hardy, meaning they will not survive a freeze. At Longfield Gardens, we advise waiting until the soil has warmed up and the threat of frost is completely gone before planting them outdoors. If you want more help on timing and planting basics, our begonia planting guide for a stunning shade garden is a great next step.
The 60-Degree Rule
Begonias are happiest when nighttime temperatures are consistently above 50°F, but they truly start to grow once temperatures hit 60°F. If you plant them too early in cold, damp soil, the tubers or roots may struggle or even rot before they have a chance to grow. If an unexpected late frost is predicted, be sure to cover your outdoor begonias or bring containers into a garage or shed.
Managing Humidity and Airflow
Many begonias, especially Rex varieties, enjoy a humid environment. However, high humidity combined with still air can lead to powdery mildew. This looks like a light dusting of white flour on the leaves.
To prevent this, ensure your begonias have plenty of room. Don't crowd them too closely together. Good airflow allows the leaves to dry out after a rain or watering, which keeps the plant healthy. When watering, try to aim the nozzle at the base of the plant rather than spraying the leaves. Keeping the foliage dry is a simple way to avoid most fungal issues.
Best Outdoor Locations for Begonias
Choosing the right physical location in your landscape is the next step. Since we know begonias like shade and well-draining soil, we can look for specific spots that meet these needs.
Underneath Tree Canopies
The space under a large deciduous tree is often a difficult place to grow flowers because of the shade. However, this is exactly where tuberous begonias like to be planted. The tree provides "dappled shade," where bits of sunlight peek through the moving leaves. This mimics the natural forest floor environment where many wild begonias originate. Just be sure to provide extra water, as the tree's roots will be competing for moisture.
North-Facing Porches and Walls
The north side of a house or a garage is often permanently shaded. While many flowers refuse to bloom in these dark spots, begonias will fill the space with color. Wax begonias are especially useful for edging a north-facing walkway. They stay compact and provide a neat, tidy border that lasts all summer.
Window Boxes and Hanging Baskets
Begonias are classic choices for window boxes that don't get much sun. Trailing tuberous varieties are spectacular in hanging baskets. Because these locations are elevated, they usually have excellent drainage. However, keep in mind that pots and baskets dry out much faster than the ground. In the heat of mid-summer, a hanging begonia may need water every day.
Shaded Courtyards and Patios
If you have a small courtyard or a patio with a pergola, begonias can add a lush, "urban jungle" feel. Using different heights of pots can create a tiered wall of color. We suggest placing taller cane begonias (like Angel Wings) in the back and shorter wax or Rex begonias in the front.
Planting Begonias in Containers
Many gardeners find that begonias are easiest to manage in containers. This allows you to move the plants around if you realize a spot is getting too much sun or wind. It also makes it easier to control the soil quality.
Choosing the Right Pot
When selecting a container, the most important feature is the drainage hole. Without a hole in the bottom, water will collect at the base and drown the roots. If you have a beautiful decorative pot that doesn't have a hole, use it as a "cachepot." Plant the begonia in a plain plastic nursery pot with holes, then set that pot inside the decorative one.
Proper Spacing
Begonias don't mind being slightly snug in their pots, but they shouldn't be cramped.
- For a 10-inch pot, one or two plants is usually sufficient.
- In a large 14-inch container, you can fit three to four plants.
- For tuberous begonias grown from tubers, plant them about 8 to 10 inches apart.
Depth Matters
If you are planting begonias that you bought in nursery pots, plant them at the same depth they were in the pot. If you are starting from tubers, place them about an inch deep with the "hollow" or indented side facing up. This is where the new growth will emerge.
Key Takeaway: Use containers to your advantage. They allow you to provide the perfect "soilless" environment and the flexibility to chase the shade as the sun moves throughout the season.
Indoor Locations for Begonias
Some begonias are just as happy inside your home as they are in the garden. Rex begonias and Angel Wing begonias are particularly popular as houseplants.
The Best Windows
Indoors, begonias like to be planted—or rather, placed—near an east-facing or west-facing window. An east-facing window provides gentle morning sun, which is perfect. A south-facing window might be too hot and bright, so you may need to move the plant a few feet back from the glass or use a sheer curtain to filter the light.
Bathrooms and Kitchens
Because begonias appreciate humidity, they often thrive in bathrooms or near kitchen sinks. The steam from showers and cooking provides the moist air they crave. If your home is very dry, especially in the winter, you can place the pot on a tray filled with pebbles and a little water. As the water evaporates, it creates a humid microclimate around the plant.
Avoiding Drafts
Begonias do not like sudden changes in temperature. Avoid placing them directly in front of air conditioning vents or heaters. These drafts can dry out the leaves quickly and cause the plant to drop its flowers.
Protecting Begonias from Wind
One factor that is often overlooked is wind. Begonias, particularly the tall cane types and the large-flowered tuberous types, have brittle stems. These stems are succulent and filled with water, which makes them heavy but easy to snap.
Finding a Sheltered Spot
When deciding where to plant, look for a location that is protected from strong gusts. A spot near a fence, a hedge, or the side of the house can provide a windbreak. If you are growing tall begonias in a windy area, you may need to provide a small bamboo stake for support.
Hanging Basket Safety
If you have begonias in hanging baskets, be mindful of stormy weather. Strong winds can toss baskets around, breaking the trailing stems. If a storm is coming, it is a good idea to take the baskets down and set them on the ground in a protected area until the weather passes.
Creating Companion Plantings
Begonias look beautiful on their own, but they also play well with others. When choosing companions, you must pick plants that like the same "home" as a begonia—shaded, moist, and well-drained. For more ideas, browse our what to plant with begonias in containers guide.
Foliage Friends
Pairing begonias with other foliage-heavy plants can create a sophisticated look.
- Ferns: The delicate, lacy texture of ferns provides a wonderful contrast to the bold, solid leaves of a begonia.
- Hostas: Since hostas come in many sizes and shades of green and blue, they make a sturdy backdrop for colorful begonias.
- Caladiums: These plants love the same warm, shaded conditions as begonias and offer heart-shaped leaves in white, pink, and red.
Flowering Partners
If you want a mix of blooms, look for other shade-loving annuals.
- Fuchsia: These look stunning alongside trailing begonias in hanging baskets.
- Impatiens: Classic impatiens provide a carpet of color that complements the more structured look of begonias.
- Browallia: Also known as the bush violet, these small blue flowers pop against the warm tones of most begonias.
What to do next:
- Map out the shady spots in your garden.
- Group plants with similar water needs together to make maintenance easier.
- Experiment with one "foliage" companion and one "flowering" companion in a single large pot.
Realistic Expectations for Your Begonias
While we strive to provide the best advice, it is important to remember that gardening is a partnership with nature. Your local weather, the quality of your tap water, and even the specific microclimate of your yard will affect how your begonias grow.
For example, a begonia planted in the deep south will require much more shade and water than one planted in the Pacific Northwest. If you have a particularly hot and dry summer, your begonias might take a "break" from blooming until the temperatures cool down. This is normal. The plants are simply conserving energy.
Growth rates also vary. Tuberous begonias can take a few weeks to sprout from a tuber, so don't be discouraged if you don't see green shoots immediately. Once they start, they grow quickly and will reward your patience with a spectacular show.
Troubleshooting Your Plant's Location
If your begonia doesn't look quite right, it might be telling you that it doesn't like where it was planted. Here is how to read the signs and make simple adjustments.
Pale or Yellowing Leaves
If the leaves are turning pale or yellow, but the veins remain green, the plant might be getting too much sun. Try moving the container to a shadier spot or providing a bit of temporary shade with other taller plants. It could also mean the soil is too wet. Check the drainage holes to ensure they aren't blocked.
Dropping Flowers and Buds
Begonias sometimes drop their buds if they are stressed. The most common causes are extreme heat or inconsistent watering. If you find your plant dropping flowers during a heatwave, try to move it to the coolest, shadiest spot you have and keep the soil consistently moist.
Small Leaves and Few Blooms
If your begonia is healthy but seems "stuck" and small, it may not be getting enough light. Even shade-loving plants need some brightness to create energy for flowers. Move it to a spot with more filtered light or a bit of morning sun.
Conclusion
Finding the right spot for your begonias is the most important step in ensuring a season full of color. Remember that most begonias love the shade, require well-draining soil, and need protection from the cold and wind. By matching your variety to its preferred environment, you take the guesswork out of gardening and set yourself up for a beautiful result.

FAQ
Can I plant begonias in full sun?
It depends on the variety. Most tuberous and Rex begonias will scorch in full sun. However, certain wax begonias and hybrid varieties, like the Surefire begonias, can handle significantly more sun if they are kept well-watered and live in a region with moderate summer temperatures.
Do begonias grow better in pots or in the ground?
Both can work, but many gardeners prefer pots because it is easier to provide the loose, well-draining soil begonias love. Containers also allow you to move the plants to follow the shade or protect them from unexpected weather. If you want more container-specific tips, revisit our begonia in pots guide.
Why are the leaves on my begonia turning brown at the edges?
This is usually a sign of "leaf scorch," which happens when the plant gets too much direct sunlight or the air is too dry. Move the plant to a more shaded location and ensure the soil stays evenly moist.
How much shade is "too much" for a begonia?
While begonias love shade, they still need some light to produce flowers. If your begonia is in a very dark corner and isn't blooming, try moving it to a spot with "bright indirect light" or dappled sunlight. One or two hours of gentle morning sun is often beneficial for most types. For more shade-specific guidance, see our will begonias grow in the shade guide.
