Introduction
Few things bring more joy to a garden than the first lush, rose-like blossoms of a begonia tucked into a shady corner. These plants are famous for their ability to transform dim areas into vibrant displays of color. Whether you are looking to brighten a front porch with hanging baskets or fill a garden bed under a sprawling oak tree, begonias are a reliable and beautiful choice.
At Longfield Gardens, we want to help you make the most of these versatile plants by finding the perfect spot for them to thrive. While begonias are known for being easy to grow, their success depends heavily on where they are placed. Choosing a location that balances light, moisture, and protection from the elements is the key to a season full of flowers.
This guide will help you identify the best locations in your yard and home for different types of begonias. We will cover lighting needs, soil requirements, and how to use your local environment to your advantage. By the end of this article, you will know exactly where to plant a begonia to ensure it stays healthy and blooms from summer through the first frost.
Understanding Begonia Light Requirements
When people ask where to plant a begonia, the first answer usually involves shade. While most begonias enjoy protection from the sun, the exact amount of light they need can vary. Finding the "Goldilocks" zone—not too bright and not too dark—is the secret to healthy foliage and plenty of flowers.
The Magic of Dappled Light
Most begonias, especially the large-flowered tuberous begonias, prefer filtered or dappled sunlight. This is the kind of light you find under a tree with a high canopy. The leaves of the tree break up the direct rays of the sun, creating a moving pattern of light and shadow on the ground. This prevents the begonia leaves from scorching while still providing enough energy for the plant to produce blooms.
Morning Sun vs. Afternoon Sun
If you cannot provide dappled light all day, aim for a spot that receives gentle morning sun. The sun is much cooler before noon. Three to four hours of morning light followed by afternoon shade is often an ideal setup. The intense heat of the afternoon sun, especially in the southern United States, can quickly wilt a begonia and burn its tender leaves.
Identifying Deep Shade
While begonias are shade-tolerant, they are not "no-light" plants. If you plant them in a spot that is dark all day, such as under a very low-hanging evergreen or in a narrow alleyway between tall buildings, they may struggle. In deep shade, begonias often become "leggy." This means the stems grow long and thin as the plant stretches toward the light. You will also see fewer flowers in these conditions.
Key Takeaway: For the best results, look for a spot with filtered light or morning sun. Avoid the harsh afternoon sun to keep the foliage from burning.
Evaluating Your Soil and Drainage
The "where" of planting a begonia is just as much about what is under the ground as what is above it. Begonias have relatively delicate root systems. They are very sensitive to how much water stays in the soil.
The Importance of Drainage
Drainage refers to how quickly water moves through the soil. Begonias need "well-drained" soil. This means the soil should stay moist like a wrung-out sponge, but never feel like a swamp. If a begonia sits in water for too long, the roots and the base of the stems can rot.
You can test your drainage by digging a small hole about six inches deep and filling it with water. If the water disappears in a few minutes, your drainage is excellent. If the water is still sitting there after an hour, you may need to amend the soil or choose a different spot.
Improving Your Planting Site
If your favorite garden spot has heavy clay soil that stays wet, you can still plant begonias there by making a few changes. Adding organic matter is the best way to fix drainage issues. We recommend mixing in compost, finely shredded bark, or leaf mold before planting. This creates air pockets in the soil that allow water to flow through while still holding onto the moisture the plant needs.
Using Raised Beds
If your ground soil is particularly difficult to work with, consider planting in a raised bed. Because raised beds sit above the natural grade of the yard, they drain much faster. This gives you total control over the soil quality. You can fill the bed with a high-quality mix that is specifically designed for flowering plants.
What to Do Next: Soil Preparation
- Identify your planting spot and check for standing water after a rain.
- Dig in 2-3 inches of compost to improve soil texture.
- Loosen the soil to a depth of about 6-8 inches to help roots spread easily.
- Avoid areas where roof gutters drain directly into the garden bed.
Planting in the Ground vs. Containers
Where you plant a begonia often depends on whether you want a permanent garden feature or a portable splash of color. Both options have benefits, but they require slightly different site selections.
Garden Beds and Borders
Planting in the ground is a great way to create a lush, tropical look. In garden beds, begonias are often used as "edging" plants. Because many varieties stay relatively low, they look beautiful along the front of a border.
When choosing a spot in the ground, consider the proximity to large trees. While trees provide the shade begonias love, their roots can also compete for water and nutrients. If you plant under a tree, you may need to water your begonias more frequently than those in an open bed.
The Advantage of Containers
Many gardeners prefer to plant begonias in pots, window boxes, or hanging baskets. Containers give you the ultimate flexibility. If you realize a spot is getting too much sun, you can simply pick up the pot and move it.
Containers are also the best choice for trailing begonias. Varieties with long, arching stems look spectacular when they can spill over the edges of a hanging basket. This allows the flowers to be seen at eye level, which is perfect for enjoying their intricate shapes.
Placement for Pots and Baskets
Where you hang a basket matters just as much as where you dig a hole. A hanging basket on a covered porch is a classic choice because the roof provides permanent shade. However, keep in mind that hanging baskets dry out much faster than the ground. A spot that is easy to reach with a watering can or hose is always a better choice than a high, out-of-the-way hook.
Choosing the Best Spot Based on Variety
Not all begonias are the same. The "where" changes depending on which type you have chosen. At Longfield Gardens, we offer various types that each have their own favorite environments.
Tuberous Begonias
These are the showstoppers of the begonia world. They produce huge, colorful flowers that look like roses or camellias. Tuberous begonias are the most sensitive to heat and direct sun. They belong in the coolest, shadiest parts of your yard. North-facing porches or the north side of a house are often the most successful spots for these varieties.
Wax Begonias
Wax begonias are the workhorses of the shade garden. They are more tolerant of a variety of conditions than tuberous types. Interestingly, the color of the leaves can tell you where to plant them.
- Green-leaved varieties: These prefer more shade and can scorch if they get too much sun.
- Bronze-leaved varieties: These have a higher tolerance for sunlight. If you have a spot that gets a bit more than four hours of sun, a bronze-leaved wax begonia is your best bet.
Rex Begonias
Rex begonias are grown primarily for their stunning, colorful foliage. They are often kept as houseplants, but they can spend the summer outdoors. Because they are sensitive to humidity and temperature changes, they do best in a sheltered spot that is protected from strong winds. A patio table or a plant stand near the house is a great location for them.
Angel Wing and Cane Begonias
These varieties grow upright on sturdy stems. They are often more heat-tolerant than tuberous begonias. They make excellent "thriller" plants in the center of a large container. Because they can grow quite tall, they need a spot where they won't be knocked over by a gust of wind.
Key Takeaway: Match your variety to your location. Use tuberous begonias for the deepest shade and bronze-leaved wax begonias for sunnier spots.
Microclimates and Protection
A microclimate is a small area where the conditions are slightly different from the rest of your yard. Understanding these small differences helps you decide exactly where to plant a begonia for maximum success.
Wind Protection
Begonias have succulent stems. This means the stems are thick and filled with water, which makes them somewhat brittle. A strong wind can easily snap a beautiful branch filled with blooms. When picking a spot, look for natural windbreaks. Planting near a fence, a wall, or a group of sturdy shrubs can provide the protection your begonias need.
Heat Pockets
Even in the shade, some areas of your yard can get very hot. Areas near brick walls, stone patios, or concrete driveways can trap heat and radiate it back onto your plants. This is called the "heat island effect." Begonias prefer to stay cool. If you plant them near a brick wall, try to leave a few inches of space between the plant and the wall to allow for air circulation.
Air Circulation
While protection from wind is important, begonias also need fresh air. If they are planted in a spot where the air is completely stagnant, they can become susceptible to powdery mildew. This is a fungus that looks like white flour on the leaves. To prevent this, give your plants enough room to breathe. Space them according to the instructions on the packaging, usually about 8 to 12 inches apart.
What to Do Next: Site Selection Checklist
- Find a spot protected from strong, drying winds.
- Ensure the site is away from heat-reflecting surfaces like dark pavement.
- Leave enough space between plants for air to move freely.
- Check that the spot is within reach of a water source.
Regional Considerations for the United States
The United States has many different climates, and where you plant a begonia in Maine will be different from where you plant one in Georgia.
Gardening in the North
In cooler northern climates, begonias can often handle a bit more sun. The rays of the sun are not as intense, and the air temperature stays lower. If you live in a northern state, you might find that your begonias bloom better if they get a little more light than the standard "partial shade" recommendation.
Gardening in the South
In the South, shade is non-negotiable. The high heat and humidity of a southern summer can be stressful for many plants. For southern gardeners, the best spot is often one that receives only very early morning sun or is entirely in filtered shade. Ensuring your begonias have "cool feet" by using mulch can also help them survive the summer heat.
High Altitude and Inland Areas
If you live in a very dry climate or at a high altitude, the sun is even more intense. In these areas, begonias need extra protection. Humidity is also lower, so a spot near a water feature or among other leafy plants can help create a slightly more humid environment that begonias enjoy.
Using Begonias in Landscape Design
Knowing where to plant a begonia also involves thinking about how it looks with your other plants. Because they are so colorful, they can be used as focal points or as accents to highlight other features.
Brightening Dark Corners
The primary role of the begonia in landscape design is to act as a spotlight. White and light yellow begonias are particularly good at this. When planted in a dark corner, these light colors seem to glow, making the space feel larger and more inviting.
Underplanting Shrubs and Trees
Begonias are perfect for filling the empty space at the "feet" of larger plants. If you have tall shrubs like hydrangeas or rhododendrons, planting begonias in front of them creates a layered look. The shrubs provide the shade, and the begonias provide the color.
Window Boxes and Entryways
Because begonias have a long blooming season, they are excellent for areas you see every day. Planting them in window boxes or in pots near your front door ensures a cheerful greeting every time you come home.
Companion Plants for Begonias
When deciding where to plant, think about what else will grow well in that same spot. Good companions for begonias are other shade-loving plants that enjoy moist soil.
- Ferns: Their airy texture contrasts beautifully with the bold leaves of begonias.
- Hostas: These provide a sturdy, green backdrop for colorful begonia blooms.
- Caladiums: They offer colorful foliage that complements the flowers of the begonia.
- Coleus: With endless color patterns, coleus can be matched to any begonia variety.
Practical Steps for Planting Success
Once you have identified the perfect "where," you need to focus on the "how." The way you place the plant in the ground can affect how well it settles into its new home.
Planting Depth
Whether you are planting a started plant from a nursery or a tuber, depth matters. For tuberous begonias, the tuber should be planted with the indented (concave) side facing up. It should be just barely covered with soil—no more than half an inch. Planting them too deep can lead to rot before the plant even breaks the surface.
Spacing for Growth
It is tempting to plant begonias very close together for an instant full look. However, begonias will grow and spread throughout the summer. Most varieties need about 10 to 12 inches of space. This space ensures that each plant gets enough nutrients and that air can circulate around the foliage.
Initial Watering
Immediately after planting your begonia in its chosen spot, give it a good drink of water. This helps the soil settle around the roots or tuber and removes any large air pockets. Be careful not to wash away the thin layer of soil covering the plant. Use a gentle watering can or a "soaker" setting on your hose nozzle.
Key Takeaway: Plant begonias shallowly and give them plenty of room to grow. A little space and the right depth go a long way in preventing disease and encouraging health.
Ongoing Location Care
Even after you have picked the best spot, you should keep an eye on how the environment changes throughout the season.
Changing Light Patterns
As the sun moves higher in the sky during mid-summer, a spot that was shady in May might be in full sun in July. Watch your plants for signs of stress. If the leaves start to turn brown and crispy at the edges, they might be getting too much sun. If the plant is in a pot, move it. If it is in the ground, you might need to provide temporary shade or consider moving it the following year.
Managing Moisture in the Shade
Shady areas often stay wet longer than sunny ones because the sun isn't there to evaporate the moisture. This is why checking the soil with your finger is so important. Don't water on a schedule; water when the top inch of soil feels dry. Overwatering is the most common reason begonias fail, even in the "perfect" spot.
Fertilizing for Performance
In a good location, begonias will grow quickly. They are often called "heavy feeders," meaning they use a lot of nutrients to produce those constant blooms. We recommend using a balanced, water-soluble fertilizer once every few weeks during the growing season. This ensures the soil stays rich and the plant has the energy it needs to keep flowering until frost.
Conclusion
Finding the right place for your begonias is a rewarding process that sets the stage for a beautiful garden. By focusing on dappled light, well-draining soil, and protection from the wind, you create an environment where these tropical beauties can truly shine. Whether they are tucked into a border or cascading from a basket, begonias bring a level of elegance and color that is hard to match.
At Longfield Gardens, we believe that gardening should be a joyful experience. Getting the basics right—like choosing the perfect location—makes everything else easier. Once your begonias are settled in their ideal home, all that is left for you to do is enjoy the show.
- Select a spot with morning sun and afternoon shade for the best bloom production.
- Ensure your soil is loose and rich in organic matter to provide excellent drainage.
- Use containers for trailing varieties to add vertical interest to porches and patios.
- Keep plants spaced apart to encourage air circulation and prevent mildew.

FAQ
Can begonias grow in full sun?
Most begonias prefer shade, but bronze-leaved wax begonias can handle more sun than other types. In cooler northern climates, they may tolerate full sun if the soil is kept consistently moist. However, for most varieties and regions, partial shade is the safest choice to avoid leaf scorch.
What is the best side of the house to plant begonias?
The north side of a house is typically the best location for begonias because it provides consistent shade throughout the day. The east side is also a great option as it offers gentle morning sun and protection from the intense afternoon heat. Avoid the south and west sides unless there are large trees providing deep shade.
Can I plant begonias under a tree?
Yes, begonias thrive under trees because they provide the dappled light the plants love. However, be aware that tree roots can be very thirsty and may soak up all the available water. You will need to check the soil moisture more frequently and may need to water your begonias more often than those in other areas.
Do begonias need to be in a pot or can they go in the ground?
Begonias do well in both environments. Containers are excellent for trailing varieties and allow you to move the plants if the light is too intense. Planting in the ground is ideal for creating mass color displays or edging along shady garden paths, provided the soil has good drainage.
