Introduction
There is a special kind of excitement that comes with finding the perfect plant to brighten up a dark corner of the yard. Begonias are the champions of these shaded spaces, offering a lush tropical look and a color palette that rivals any sun-loving flower. Whether you are looking for the massive, rose-like blooms of tuberous begonias or the jewel-toned leaves of the Rex variety, these plants bring reliable beauty to almost any home landscape.
At Longfield Gardens, we want to make it easy for you to enjoy a garden full of vibrant life. This guide is for home gardeners who want to know exactly where to tuck these versatile plants for the most successful growing season. We will cover the ideal light conditions, the best soil types, and how to choose the right location based on the specific variety you have.
Understanding where to plant begonias is the first step toward a summer filled with nonstop flowers and stunning foliage.
Choose the Right Light for Your Begonias
The most common question gardeners ask is whether begonias prefer sun or shade. The answer is usually a bit of both, but it depends heavily on the specific type of begonia you are growing. While most begonias are famous for loving the shade, they still need some light to produce their signature flowers. For a broader look at timing and placement, see our begonia planting guide.
The Magic of Filtered Light
In their native habitats, many begonias grow on forest floors under a canopy of trees. This means they are adapted to "dappled" or "filtered" light. This is the light that peeks through the leaves of a tree, creating a moving pattern of sun and shade on the ground.
A spot under a high-canopy tree is often the perfect home for your begonias. It protects them from the harsh, direct rays of the sun while providing enough energy for the plant to thrive. If you have a spot that feels bright but doesn't have the sun beating down directly on it, your begonias will likely be very happy there.
Morning Sun vs. Afternoon Sun
If you don't have a wooded area, look for a spot that receives morning sun and afternoon shade. The morning sun is much cooler and less intense than the sun that hits between noon and 4:00 PM.
Most begonias, especially the large-flowered tuberous types, can handle a few hours of gentle morning light. However, the hot afternoon sun can quickly scorch their tender leaves and cause the flowers to wilt. A north-facing or east-facing side of your home is often an ideal location.
Identifying Sun-Tolerant Varieties
Some modern begonias are bred to handle more sun than traditional types. For example, wax begonias and certain hybrid varieties like the Surefire series are much more resilient. If you have a spot that gets more than four hours of sun, look for varieties with bronze or dark-colored foliage.
Darker leaves contain more pigments that help protect the plant from sun damage. Green-leaved begonias are generally more sensitive and should stay in more protected, shadier spots. Even "sun-tolerant" begonias usually appreciate some protection during the hottest part of the day in warmer climates.
Key Takeaway: Match your begonia’s leaf color to its location. Green leaves prefer deep to partial shade, while bronze or dark leaves can handle more morning sun.
Finding the Best Soil Conditions
Once you have identified the right light, the next step is looking at the ground. Where you plant begonias matters just as much as the light they receive, especially when it comes to "drainage." Drainage simply refers to how fast water leaves the soil after a rain or watering. If you're unsure about timing and weather windows, our safe planting guide can help.
The Importance of Drainage
Begonias have succulent stems and roots (or tubers) that store a lot of water. Because of this, they are very sensitive to "wet feet," which happens when the soil stays soggy for too long. If the roots sit in water, they can easily rot.
When choosing a spot in your garden, avoid low areas where water naturally puddles after a rainstorm. You want a site where the soil is loose and crumbly. If your soil is heavy clay, it may hold onto water too tightly. You can improve this by mixing in organic matter like compost or finely ground bark to help create more space for air and water to move.
Soil Quality and Nutrients
Begonias are "heavy feeders," meaning they use a lot of nutrients to produce those big blooms and beautiful leaves. They prefer soil that is rich in organic matter. A simple way to prepare a planting site is to turn over the soil and mix in a few inches of high-quality compost.
We find that begonias do best in soil that is slightly acidic. Most standard garden soils are fine, but if you know your soil is very alkaline, adding some peat moss or compost can help bring the pH into the preferred range for these plants.
What to Do Next: Soil Prep
- Check for puddles 5–6 hours after a heavy rain.
- If water remains, choose a different spot or use a raised bed.
- Mix in 2–3 inches of compost to improve drainage and nutrients.
- Ensure the planting area is loose and easy to dig.
Strategic Locations in the Landscape
Where you plant begonias can change the entire feel of your yard. Because they are so versatile, you can use them in several different ways to solve common gardening challenges.
Underneath Shade Trees
Many plants struggle to grow under trees because of the lack of light and competition for water. Begonias are one of the few exceptions. Since they love filtered light, they are perfect for filling in the bare spots under a large maple or oak tree. For more on spacing and placement, see our bedding begonia spacing guide.
When planting under trees, be sure to give them a little extra water during dry spells. Large trees act like big umbrellas and can prevent rain from reaching the ground directly beneath them. They also have large root systems that can soak up moisture quickly.
Along Borders and Walkways
Wax begonias are fantastic for edging. Their compact, mounded shape makes them look neat and tidy all season long. Planting them in a long row along a shaded walkway creates a colorful "ribbon" effect. Since they are "self-cleaning" (meaning you don't have to pull off the old flowers), they stay looking fresh with very little work on your part.
North-Facing Foundations
The north side of a house is often a difficult place to garden because it stays in the shadow of the building for most of the day. This is a prime location for begonias. It provides the consistent shade they crave and protects them from drying winds. You can create a beautiful layered look by planting taller shade perennials like hostas in the back and shorter begonias in the front.
Planting Begonias in Containers
If you don't have the right soil in your garden, containers are the perfect solution. In fact, many people prefer growing begonias in pots because it gives them total control over the environment.
Choosing the Right Pot
Begonias grow beautifully in ceramic pots, plastic containers, and window boxes. The most important feature of any pot you choose is the drainage hole. Without a hole for excess water to escape, the soil will become waterlogged. For a ready-made container option, our Non Stop Begonias collection is a smart place to start.
If you are planting trailing tuberous begonias, hanging baskets are a wonderful choice. Varieties like the Illumination or Waterfall series will spill over the edges, creating a curtain of color on a porch or patio. For upright varieties, a classic flower pot provides a sturdy base for their lush growth.
Using High-Quality Potting Mix
Never use "garden soil" or "topsoil" in a container. It is too heavy and will pack down, preventing the roots from getting the air they need. Instead, use a high-quality "soilless" potting mix. These mixes are usually made of peat moss, perlite, and pine bark. They are designed to stay light and fluffy while holding just the right amount of moisture.
Positioning Your Containers
The beauty of containers is that you can move them! If you notice your begonias are looking a bit scorched, you can slide the pot into a shadier spot. If they aren't blooming well, you can move them to a place with a bit more morning light.
Covered porches and patios are excellent spots for containers. They provide "bright shade," which is a perfect environment for begonias. Just remember that pots dry out faster than the ground, so you will need to check the moisture level more often.
Key Takeaway: Containers allow you to provide the perfect "soilless" environment for begonias, making them a great choice for beginners or those with poor garden soil.
Protecting Begonias from the Elements
Because begonias have soft, succulent stems, they can be a bit fragile. Choosing a protected location will help prevent damage from the weather.
Guarding Against Wind
Begonias have large leaves that can act like sails in a storm. High winds can snap the stems or tear the foliage. When deciding where to plant begonias, look for a spot that is shielded from the prevailing winds. Planting them near a fence, a wall, or a cluster of larger shrubs can provide the windbreak they need to stay safe.
Managing Air Circulation
While protection from wind is important, begonias also need a little bit of air movement. If the air is too stagnant and the foliage stays wet for long periods, they can develop powdery mildew. This is a fungal issue that looks like white dust on the leaves.
To prevent this, give your plants some space. Instead of crowding them together, leave a few inches between each plant. This allows air to flow through the foliage, keeping the leaves dry and healthy. For more on container groupings and companion plantings, try our begonia companion guide.
Temperature Sensitivity
Begonias are tropical plants. They love warmth but hate extreme heat and cold. In most parts of the United States, they should only go outside once the soil has warmed up and all danger of frost has passed.
A good rule of thumb is to wait until nighttime temperatures are consistently above 50°F (10°C). If you plant them too early in cold, damp soil, they may sit and struggle or even rot. Patience is a virtue when it comes to these tropical beauties!
Matching Varieties to Locations
Not all begonias are created equal. To get the best results, you should match the type of begonia to the specific spot you have in mind.
Tuberous Begonias: The Shade Lovers
Tuberous begonias produce some of the most spectacular flowers in the garden. They come in two main forms: upright and trailing.
- Where to plant: Shady patios, north-facing window boxes, and hanging baskets.
- Light: Deep shade to filtered light. They are the most sensitive to heat and sun.
Wax Begonias: The Versatile All-Stars
Wax begonias (also called fibrous begonias) are the workhorses of the garden. They have glossy, waxy leaves and smaller, more frequent flowers.
- Where to plant: Garden borders, mass plantings in beds, and mixed containers.
- Light: They can handle more sun than other types, especially if they have bronze leaves.
Rex Begonias: The Foliage Specialists
Rex begonias are grown for their incredible leaves, which can feature swirls of silver, purple, pink, and burgundy.
- Where to plant: Tabletop containers, shaded entryways, or even indoors as houseplants.
- Light: Indirect light or heavy shade. Direct sun will quickly fade their beautiful colors.
Cane Begonias: The Upright Elegance
Often called "Angel Wing" begonias because of their leaf shape, these plants grow on tall, bamboo-like stems.
- Where to plant: Large floor pots on a shaded deck or as a focal point in a shaded garden bed.
- Light: Bright, indirect light. They can tolerate a bit more light than Rex begonias but still need protection from the midday sun.
Indoor vs. Outdoor Placement
Many begonias are just as happy inside your home as they are in the garden. If you live in a colder climate, you can even transition your plants between the two. If you are moving plants in or out, our hardening-off article walks through the process.
Growing Begonias as Houseplants
Rex and Cane begonias make excellent houseplants. Indoors, the best place for them is near a window that gets bright, indirect light. An east-facing window is usually perfect. Avoid placing them directly in a south-facing window where the sun might be too intense.
Begonias also appreciate a bit of humidity. If your home is very dry, especially in the winter, placing your pots on a tray filled with pebbles and water can help. Just make sure the pot is sitting on the pebbles, not in the water.
Moving Begonias Outdoors for Summer
If you have begonias that live indoors during the winter, they will love a "vacation" outdoors in the summer. However, you shouldn't just move them from a dark living room to a sunny porch all at once.
This process is called "hardening off." Start by putting them in a very shady, protected spot for a few hours a day. Over the course of a week or two, gradually increase their time outside and their exposure to light. This gives the leaves time to toughen up and adjust to the outdoor environment.
Bringing Them Back Inside
Before the first frost in the fall, you can bring your begonias back indoors. Give them a quick check for any hitchhiking insects and spray them down with a gentle stream of water. They may drop a few leaves as they adjust to the lower light levels inside, but they will soon settle in.
Caring for Begonias in Their New Home
Once you have found the perfect place to plant begonias, a little bit of ongoing care will ensure they stay beautiful all summer long. For more seasonal pointers, the best-time-to-plant guide is a helpful follow-up.
Water Correctly, Not Constantly
The secret to watering begonias is to let the top inch of soil dry out before you water again. Stick your finger into the soil—if it feels damp, wait a day or two. If it feels dry, give the plant a good, deep drink.
Always try to water at the base of the plant. Getting water on the leaves can lead to spots or fungal issues. In containers, you may need to water every day during the peak of summer, but always check the soil first.
Feeding for Better Blooms
Since begonias bloom for such a long time, they need plenty of energy. We recommend using a balanced, water-soluble fertilizer about once a month during the growing season. This provides the nutrients the plant needs to keep producing new flowers and lush foliage. If you are growing begonias mainly for their leaves (like Rex types), a fertilizer with a bit more nitrogen can help.
Simple Maintenance
Most modern begonias are very low-maintenance. Wax begonias and hybrid types like "Surefire" don't need deadheading (removing old flowers). Tuberous begonias might benefit from a quick cleanup once a week just to keep the plant looking its best. If your plants start to look a bit "leggy" or stretched out, don't be afraid to pinch off the tips. This encourages the plant to grow more side branches and become fuller.
What to Do Next: Mid-Season Care
- Check soil moisture by hand every morning.
- Apply a balanced liquid fertilizer once every 4 weeks.
- Pinch back leggy stems to promote a bushier shape.
- Clear away fallen leaves or spent blooms to keep the area clean.
Troubleshooting Placement Issues
Sometimes, despite our best efforts, a plant might not look quite right. If your begonias are struggling, their appearance can give you clues about how to adjust their location.
Leaves Turning Yellow or Brown
If the leaves are turning yellow and the stems feel mushy, the plant is likely getting too much water. This often happens in spots with poor drainage. Try moving the plant to a drier location or a pot with better soil.
If the edges of the leaves are turning brown and crispy, the plant is likely getting too much sun or the air is too dry. Move it to a shadier spot or a location with better protection from the wind.
Few Flowers and Long Stems
If your begonia is growing tall and spindly but isn't producing many flowers, it is probably too shaded. While begonias love shade, they still need "bright" light to bloom. Try moving the plant to a spot where it gets a little more morning sun or filtered light.
Stunted Growth
If your begonias aren't growing at all, it might be too cold. Remember, these are tropical plants that stop growing when temperatures dip. If you planted them early in the season, they may just be waiting for the soil to warm up. Give them some time, and they should take off once the summer heat arrives.
Summary of Where to Plant Begonias
Finding the right home for your begonias is the most important part of their care. When you match the plant’s needs to the right spot, the rest of the gardening work becomes much easier.
- Look for filtered light: Most begonias thrive in the "dappled" sun found under trees or on shaded porches.
- Prioritize drainage: Choose loose soil or use high-quality potting mix in containers to avoid root rot.
- Protect from wind: Soft stems need a shielded spot near walls, fences, or other plants.
- Wait for warmth: Only plant outdoors when the soil is warm and nights are above 50°F.
- Match variety to site: Use Wax begonias for sunnier borders and Tuberous or Rex begonias for deeper shade.
At Longfield Gardens, we believe that gardening should be a rewarding and enjoyable experience for everyone. By following these simple rules for placement, you can enjoy the lush, tropical beauty of begonias in your own yard all season long.
Gardening is about the joy of watching things grow. Start with a healthy plant and a well-chosen spot, and you are already halfway to a beautiful garden.

FAQ
Can begonias grow in full sun?
Most begonias prefer shade or partial sun. However, wax begonias and certain hybrids with bronze or dark leaves can tolerate more sun than green-leaved varieties. In very hot climates, even sun-tolerant types usually need protection from the intense afternoon sun to prevent leaf scorch.
What is the best soil for planting begonias?
Begonias need rich, well-draining soil. In garden beds, you should amend the soil with compost to improve both the nutrients and the drainage. For containers, always use a light, soilless potting mix rather than garden soil to ensure the roots get enough air and don't sit in water.
Can I plant begonias in the ground and in pots?
Yes, begonias are very versatile and thrive in both locations. Upright varieties are excellent for garden beds and borders, while trailing varieties are better suited for hanging baskets and window boxes. Pots are often easier for beginners because they provide better control over soil quality and drainage.
How do I know if my begonias are getting too much shade?
If a begonia is in too much shade, it will often become "leggy," meaning the stems grow long and thin as they reach for the light. You may also notice fewer flowers or very small leaves. If this happens, move the plant to a location with slightly more bright, indirect light or a few hours of morning sun.
