Introduction
Finding the perfect spot for your plants is one of the most rewarding parts of gardening. There is a unique sense of excitement when you tuck a tuber into the soil, knowing that in a few months, it will transform into a lush display of color. Begonias are particularly special because they bring brilliant reds, soft pinks, and cheerful yellows to the quieter, shaded corners of your yard. At Longfield Gardens, we enjoy helping home gardeners find the right varieties to turn every corner of the landscape into a beautiful retreat.
Whether you are looking to fill a hanging basket on a porch or brighten a border under a tall oak tree, knowing exactly where to plant begonias is the first step toward success. These versatile plants are famous for their ability to thrive where many other flowers struggle. This guide is designed for gardeners who want to understand the best environments for begonias to ensure a season full of healthy growth and nonstop flowers.
Choosing the right location depends on matching the specific needs of the begonia variety with the light, soil, and shelter available in your yard.
Assessing Light Conditions
The most common question about where to plant begonias usually centers on sunlight. Most begonias are known as summer flowers for shade, but "shade" can mean many things in a typical backyard. The amount of light a spot receives will change throughout the day and across the seasons.
The Beauty of Dappled Shade
Tuberous begonias , which are prized for their large, rose-like blossoms, prefer dappled or filtered light. This is the kind of light you find under a tree with a high, open canopy. The leaves of the tree break up the direct rays of the sun, allowing soft light to reach the plants below. This prevents the delicate petals and succulent leaves from scorching while still providing enough energy for the plant to produce plenty of flowers.
Partial Shade and Morning Sun
If you have a spot that gets direct sun in the morning but is shaded by 11:00 AM, this is often an ideal location for many varieties. Morning sun is cooler and less intense than the harsh afternoon sun. A north-facing or east-facing garden bed or porch is usually a safe bet. If a begonia gets too much hot afternoon sun, the leaves may turn crisp and brown at the edges, and the flowers might wilt prematurely.
Sun-Tolerant Varieties
While most begonias shy away from high heat, wax begonias are a bit sturdier. Varieties with bronze-colored foliage are specifically bred to handle more sun than their green-leafed counterparts. These are excellent choices for garden borders that might receive six hours of sun. However, even these tougher varieties appreciate a break from the heat in the middle of the day if you live in a very warm climate.
Key Takeaway: Most begonias perform best in "part shade," which means they should receive about 4 to 6 hours of indirect or filtered light each day, preferably avoiding the intense heat of the mid-afternoon.
Finding the Right Soil and Drainage
Once you have identified a spot with the right light, the next factor is what lies beneath the surface. Begonias have relatively shallow root systems and stems that hold a lot of moisture. This makes them sensitive to how water moves through the ground.
Understanding Drainage
"Drainage" is simply a term for how fast water leaves the soil. Begonias need "well-drained soil," which means the water should soak in and move through easily rather than sitting in a puddle. If you plant a begonia in a low spot where water gathers after a rainstorm, the roots may stop "breathing" and can eventually rot.
Improving Your Soil
If your soil is heavy like clay, it can hold onto water too tightly. You can improve these areas by adding organic matter like compost or aged bark. This creates more space between soil particles, allowing air and water to move freely. For gardeners using containers, a high-quality potting mix is usually perfect because it is designed to stay fluffy and drain well.
Soil pH and Nutrition
Begonias generally prefer soil that is neutral to slightly acidic. They are not overly demanding when it comes to nutrients, but they do enjoy a steady supply of "food" to keep their blooms coming. A spot with "fertile" soil—meaning soil rich in organic matter—will give them a great head start.
What to do next:
- Observe your garden after a heavy rain to identify any areas where water stands for more than an hour.
- Avoid these "wet feet" spots for your begonias.
- If your soil feels like heavy modeling clay, consider planting in raised beds or containers to ensure better drainage.
Planting Begonias in Containers
Many gardeners find that the best place to plant begonias is in a pot, urn, or hanging basket. Containers offer you total control over the environment, which can make gardening feel much simpler and more successful.
Porches and Patios
A covered porch is often the ultimate "home" for a begonia. The roof provides built-in protection from heavy rain and direct overhead sun, while the open sides allow for plenty of fresh air. Trailing tuberous begonias are especially effective, as their heavy flower heads can drape over the sides, creating a waterfall of color at eye level.
Window Boxes
Window boxes on the north or east side of a house are fantastic locations. They allow you to enjoy the intricate details of the foliage and flowers from both inside and outside your home. Just ensure the window box has drainage holes so the soil doesn't become waterlogged during a rainstorm.
Moving for the Season
One of the best advantages of container planting is mobility. If you notice your begonia is looking a bit pale (which could mean too much shade) or the leaves are starting to scorch (too much sun), you can simply pick up the pot and move it to a better location. This flexibility is perfect for beginners who are still learning the "microclimates" of their yard.
"Containers are like mobile garden beds; they allow you to place high-impact color exactly where you want it while giving the plants the specific soil and drainage they crave."
Garden Beds and Landscaping
If you prefer to plant directly in the ground, begonias can create stunning mass displays. Because they stay relatively compact, they are excellent for borders.
Under Trees and Near Shrubbery
Planting begonias under a canopy of trees is a classic choice. They fill the space with color where grass often struggles to grow. When planting near trees, just be mindful of large tree roots. It is often easiest to plant begonias in the "pockets" between major roots. Adding a few inches of fresh compost to the area before planting can help provide the begonias with the nutrients they need to compete with the tree.
Walkways and Borders
Wax begonias are a staple for lining walkways. Their uniform growth habit creates a neat, tidy edge. When planting along a path, space them about 8 to 12 inches apart. This gives them enough room to grow into each other, forming a continuous ribbon of color by mid-summer.
The "North Side" Advantage
The north side of a house or a tall fence is often a "dead zone" for sun-loving flowers like zinnias or marigolds. However, for begonias, this is prime real estate. The structure provides a permanent shadow that keeps the soil cool and the light consistent. We often suggest these spots for Rex begonias, which are grown primarily for their stunning, multi-colored leaves rather than their flowers.
Protection from the Elements
The physical structure of a begonia is quite unique. Their stems and leaves are "succulent," meaning they are thick and filled with water. While this helps them stay hydrated, it also makes them somewhat brittle.
Sheltering from Wind
A very windy corner is usually not the best place for tall or trailing begonias. Strong gusts can snap the heavy stems or tear the large, delicate leaves. If your yard is particularly breezy, try to plant your begonias near a fence, a wall, or a group of sturdier shrubs that can act as a windbreak.
Heavy Rain Considerations
While begonias love moisture, a heavy, pounding rain can sometimes damage the large blooms of tuberous varieties. If you are planting in an area that isn't under a roof (like a porch), try to place them where they won't be hit by "roof runoff"—the heavy stream of water that pours off a gutterless roofline during a storm.
Temperature and Warmth
Begonias are tropical plants by nature. They truly thrive when the air and soil are warm. In most parts of the United States, the best "where" is a spot that stays consistently above 60°F at night. If you plant them too early in a spot that is still cold and damp from spring, they may sit idle or struggle. Patience is a quiet winner here; waiting for the right warmth makes a big difference.
Summary of ideal locations:
- Best for Tuberous Begonias: Hanging baskets on a shaded porch or dappled light under a tree.
- Best for Wax Begonias: Garden borders that receive morning sun or light afternoon shade.
- Best for Rex Begonias: Deeply shaded spots or indoors as houseplants near a bright window.
- Best for All Varieties: Anywhere with "well-drained" soil and protection from strong winds.
Transitioning Begonias Indoors
Because begonias are so well-suited to lower light levels, they are one of the few garden plants that can make a successful transition to life as a houseplant. If you have a variety you particularly love, you can move its container inside before the first frost of autumn.
The Best Indoor Spot
Inside the home, the "where" remains similar: bright but indirect light. A window facing east or west is usually perfect. Avoid placing them directly in front of a south-facing window where the glass can magnify the sun's heat, and keep them away from heating vents, which can dry out the air too much.
Tuber Storage
If you don't want to keep the plant growing all winter, tuberous begonias can be tucked away in a cool, dry spot. Many gardeners move their tubers to a basement or garage that stays around 50°F. This allows the plant to rest before starting the cycle again next spring.
Regional Timing and Your Zone
While "where" you plant is critical, "when" you plant in that spot also matters. Because we ship our bulbs and tubers based on your USDA hardiness zone, your order will typically arrive when it is nearly time to plant.
If you live in a very warm climate (like Florida or parts of the Southwest), your begonias may need even more shade than a gardener in a cooler northern state. In the North, the summer sun is less intense, so begonias can often handle a bit more light. This is why we always say gardening advice depends on your specific sun and soil.
At Longfield Gardens, we want your gardening experience to be as relaxing and successful as possible. By choosing a spot with gentle light, excellent drainage, and a bit of shelter, you are setting the stage for a spectacular show. Begonias are rewarding plants that ask for very little once they are in the right home.
Simple Steps for Success:
- Pick a spot with dappled light or morning sun.
- Check that the soil drains well and doesn't hold standing water.
- Space plants 8 to 12 inches apart to allow for airflow.
- Protect the brittle stems from strong winds.

FAQ
Can begonias grow in full shade?
Yes, many begonias thrive in full shade, which is defined as an area that receives less than four hours of direct sunlight. Rex begonias and certain fibrous varieties are especially well-suited for these darker spots. However, "full shade" should still have some ambient light; completely dark corners with no light at all will result in leggy plants with fewer blooms.
Do begonias do better in pots or in the ground?
Begonias can thrive in both, but many gardeners find them easier to manage in pots. Containers naturally provide the excellent drainage that begonias require and allow you to move the plants if the light or wind conditions aren't ideal. Tuberous begonias, in particular, are stunning in hanging baskets where their flowers can be easily seen.
Is it okay to plant begonias in the sun?
Most begonias will struggle in the intense, direct sun of the afternoon, which can scorch their leaves. However, wax begonias—especially those with bronze foliage—are much more sun-tolerant and can handle several hours of sunlight. If you plant in a sunny spot, be sure to monitor the soil moisture closely, as the sun will dry out the ground faster.
Can I plant begonias under a large tree?
Yes, under a tree is one of the best places for begonias because the canopy provides the dappled shade they love. Just be sure to check the soil moisture frequently, as tree roots are very efficient at soaking up water. You may also want to add some compost to the planting hole to help the begonias compete for nutrients.
