Introduction
There is nothing quite like the sight of a begonia in full bloom. These plants are famous for their lush, rose-like flowers and stunning foliage that can brighten even the dimmest corners of a yard. At Longfield Gardens, we see these plants as a secret weapon for home gardeners. They offer a tropical, high-end look without requiring expert-level skills. Whether you want to fill a hanging basket with trailing blooms or edge a shady walkway with color, begonias are up for the task.
Choosing where to plant your begonias is the most important step in your gardening journey. Because they come from tropical forest floors, they have specific preferences for light, moisture, and shelter. This guide will help you find the perfect spot in your yard or home. We will cover the best light conditions, soil requirements, and specific locations that help these plants thrive. By matching your plant to the right environment, you can enjoy a season of vibrant, nonstop color.
Matching the specific needs of your begonias to your unique landscape ensures a rewarding experience for gardeners of all levels.
Match the Type to the Location
Before you pick a spot, it is helpful to know which type of begonia you are planting. Different varieties have slightly different "happy places." While they all enjoy a warm environment, their growth habits and foliage can dictate where they look and perform best.
Tuberous Begonias
These are the showstoppers often found in our catalog. Tuberous begonias grow from a thick, potato-like root called a tuber. They produce large, spectacular flowers in shades of red, orange, yellow, and pink. Because their stems can be heavy with blooms, they need a location protected from strong winds. These are ideal for containers, window boxes, and hanging baskets on covered porches.
Rex Begonias
Rex begonias are grown primarily for their artistic leaves. The foliage features swirls of silver, burgundy, purple, and emerald green. Because they do not rely on heavy sun to produce flowers, they are the best choice for the deepest shade areas. They also make excellent houseplants if you have a spot with bright, indirect light.
Wax Begonias
These are the classic bedding plants you see in many local gardens. They have smaller, waxy leaves and clusters of dainty flowers. Wax begonias are much tougher than tuberous types. They can handle more sun and are often used to create a colorful border along a garden path or a mass planting in a flower bed.
Cane or Angel Wing Begonias
These varieties grow upright on stiff stems that look like bamboo. Their leaves are often shaped like wings and may have silver spots. Because they grow taller than other types, they need a spot with more vertical room. They are perfect for large patio pots where they can serve as a colorful focal point.
Key Takeaway: Always check your plant tag or the Longfield Gardens variety description. Matching the variety to your location is the easiest way to ensure success.
Choosing the Best Light Conditions
Light is the most critical factor in deciding where to plant begonias. Most begonias evolved as "understory" plants. This means they lived on the forest floor, shaded by the tall trees above. In your garden, you want to mimic this filtered, gentle light.
The Beauty of Partial Shade
Most begonias thrive in partial shade. This means a spot that gets about four to six hours of sunlight, preferably in the morning. Morning sun is cooler and less intense. After 12:00 PM, the sun becomes much hotter. This afternoon heat can scorch delicate begonia leaves, leaving them with brown, crispy edges. For more detail, see this guide to where begonias should be planted for the best sun and soil conditions.
Dealing with Deep Shade
If you have a corner of the yard that stays dark all day, such as the north side of your house, focus on Rex begonias. These foliage-heavy plants can handle lower light levels. While they may grow more slowly in deep shade, their colors will remain vibrant. Flowering begonias may produce fewer blooms if the shade is too dense, so aim for "dappled" light if you want maximum flowers.
Sun Tolerance in Certain Varieties
If your only available spot gets a lot of sun, choose wax begonias with bronze or dark-colored foliage. These darker leaves act like a natural "sunscreen" for the plant. They can handle more direct light than the green-leaved varieties. Even so, providing a bit of shade during the hottest part of the afternoon will keep them looking their best.
Signs Your Light Is Not Right
It is easy to tell if your begonia is in the wrong spot. If the plant is "leggy," meaning it has long, weak stems with a lot of space between leaves, it is reaching for more light. If the leaves look bleached, yellow, or have burnt spots, the sun is too strong. Moving a container just a few feet can often solve these issues.
Soil Quality and Drainage Needs
Once you have the light figured out, you must look at the ground. Begonias have a very specific preference for soil. They like to stay hydrated, but they hate having "wet feet." This is why understanding soil drainage for begonias is essential.
What is Drainage?
Drainage refers to how fast water leaves the soil. If water sits on top of the soil for hours after a rain, you have poor drainage. This can lead to root rot, which is when the roots literally drown and decay. Begonias need well-draining soil. This means the water should soak in and move through the soil steadily, leaving it moist but not soggy.
Improving Your Garden Soil
If your garden soil is heavy clay, it will hold too much water. You can improve this by adding organic matter. Mixing in compost, leaf mold, or finely ground bark helps create air pockets in the soil. These pockets allow water to move and roots to breathe. At Longfield Gardens, we recommend preparing your planting beds by loosening the soil to a depth of about six to eight inches before planting.
The Best Soil for Containers
If you are planting in pots, do not use "garden soil" or "topsoil" from a bag. These are too heavy for containers. Instead, use a high-quality potting mix. These mixes usually contain peat moss or coconut coir, which holds just enough moisture while allowing the rest to drain away.
Testing Your Spot
A simple way to check a potential planting spot is the "puddle test." After a heavy rain, go outside and look at the area. If you see a puddle five or six hours later, that spot is too wet for begonias. Find a higher spot or a place where the water clears quickly.
Simple Action Plan for Soil:
- Choose a spot that does not collect standing water.
- Mix in compost to improve heavy or sandy soil.
- Use fresh potting mix for all containers and hanging baskets.
- Ensure every container has at least one large drainage hole.
Planting in Garden Beds and Borders
Begonias can create a lush, carpeted look in your landscape. Because they stay relatively low to the ground, they are perfect for the front of a flower bed.
Underneath Trees
One of the best places to plant begonias is under the canopy of a large tree. The tree provides the dappled shade they love. However, be careful of the tree's roots. Do not dig deep holes that might damage the tree. Instead, tuck the begonias into small pockets of soil between the roots. This location also protects the plants from heavy rain, as the tree leaves act like a natural umbrella.
Along a North-Facing Wall
The north side of a house or a tall fence is a classic location for begonias. This area rarely gets direct, harsh sunlight but usually stays bright enough for the plants to grow. It is an easy win for gardeners who struggle to find things that bloom in the shadows of their home.
Mass Plantings for Impact
For a high-impact look, plant wax begonias in large groups. Spacing them about six to eight inches apart will allow them to grow together into a solid mound of color. This is a great way to edge a walkway or fill a small garden bed near an entryway. See this begonia spacing guide for additional planting guidance.
Avoiding "Heat Islands"
Avoid planting begonias right next to a concrete driveway or a dark-colored stone wall that gets morning sun. These surfaces absorb heat and radiate it back onto the plants. This extra heat can dry out the soil too quickly and stress the begonias, even if they are in the shade.
Selecting Spots for Container Displays
Most people enjoy growing begonias in containers. This is often the best choice because it gives you total control over the environment. You can move the pot to find the perfect light and ensure the soil is exactly what the plant needs.
Covered Porches and Patios
A covered porch is the "gold standard" for tuberous begonias. The roof protects the large, fragile blooms from being shattered by heavy rain or wind. It also provides consistent shade. Placing a few pots of pendula (trailing) begonias on a porch railing creates a beautiful, cascading waterfall of flowers.
Hanging Baskets
Hanging baskets are perfect for trailing varieties. When choosing a spot for a basket, make sure it is easy to reach. Begonias in hanging baskets dry out faster than those in the ground, so you will need to water them more often. A spot near a door or an outdoor seating area is ideal so you can enjoy the flowers up close and remember to check the moisture.
Window Boxes
Window boxes on the shady side of the house are a traditional and charming way to use begonias. They add curb appeal without requiring you to dig in the yard. Just make sure the window box is deep enough—at least six inches—to hold enough soil to keep the roots cool.
Grouping Pots for Health
If you live in a very dry climate, try grouping your begonia pots together. As the plants release moisture through their leaves, they create a small "microclimate" of higher humidity around the group. This helps keep the foliage from becoming dry and brittle.
What to Do Next:
- Walk around your porch or patio at 2:00 PM.
- Identify spots that are completely shaded from the direct sun.
- Place your largest pots in those shaded areas to serve as focal points.
- Ensure you have a saucer under indoor-outdoor pots to protect your surfaces.
Protecting Plants from Wind and Weather
Because begonias have succulent (thick and water-filled) stems, they are somewhat fragile. A strong gust of wind or a sudden summer storm can snap stems or knock off heavy flowers. Choosing a sheltered location is a key part of "where" to plant.
Using Structures for Protection
Planting your begonias near a fence, a wall, or a line of sturdy shrubs provides a natural windbreak. If you have a particularly windy yard, avoid placing begonias in open, unsheltered areas. Instead, look for "nooks" in your landscape where the air is calmer.
Dealing with Heavy Rain
While begonias love water, a heavy downpour can be tough on the large flowers of tuberous varieties. The weight of the water can cause the stems to bend or break. If a big storm is predicted, move your containers under a roof or into a garage temporarily. For begonias in the ground, planting them under a tree canopy or near the eaves of the house (but not directly under a gutter!) can provide some protection.
Airflow is Essential
While you want protection from the wind, you do not want stagnant air. Good airflow helps prevent fungal issues like powdery mildew. Avoid crowding your begonias too tightly against a solid wall or packing too many plants into one pot. A little bit of space between plants allows the leaves to dry after a rain, which keeps the plant healthy.
Indoor Locations for Begonias
Begonias are not just for the garden. Many varieties, especially Rex and Angel Wing types, are wonderful additions to your indoor decor.
The Right Window
Indoors, the best spot for a begonia is near an east-facing or west-facing window. An east-facing window provides gentle morning light. A west-facing window is also good, but you may need a sheer curtain to soften the stronger afternoon sun. North-facing windows are often a bit too dim for flowering types but can work for Rex begonias.
Kitchens and Bathrooms
Begonias love humidity. Kitchens and bathrooms are often the most humid rooms in a house, making them great locations for these plants. If your indoor air is very dry, especially in the winter, placing the pot on a tray filled with pebbles and a little water can help. The water evaporates around the plant, giving it the moisture it craves.
Temperature Consistency
Inside the house, keep begonias away from drafts. This includes air conditioning vents, space heaters, and drafty doors. Sudden changes in temperature can cause the plant to drop its leaves. They prefer the same temperatures we do—usually between 65°F and 75°F.
Timing Your Planting for Success
Knowing "where" to plant is vital, but "when" you put them there matters just as much. Begonias are tropical plants. They have no "antifreeze" in their system. This means they are extremely sensitive to cold.
The 60-Degree Rule
At Longfield Gardens, we suggest waiting until the soil temperature reaches at least 60°F before planting begonias outside. Even if the air feels warm, cold soil can stunt the growth of the tubers. A simple way to judge is to wait until you are comfortable wearing a light t-shirt outside at night.
Hardiness Zones and Shipping
Begonias are only perennial (meaning they live for many years) in USDA hardiness zones 9 through 11. In these warm areas, you can leave them in the ground year-round. In all other zones, they are grown as annuals or brought indoors for the winter. Use the Hardiness Zone Map to check your growing area. We time our shipping based on your specific gardening zone; see the Shipping Information page for details.
Starting Early Indoors
If you want a head start on the season, you can start your begonia tubers indoors about eight weeks before the last frost. Place them in a shallow tray of moist potting mix in a warm, bright spot. By the time the weather is warm enough to move them to their permanent outdoor location, they will already have several inches of growth and may even be ready to bloom. This guide to growing begonia bulbs provides additional planting information.
FAQ
Can begonias grow in full sun?
Most begonias prefer shade or filtered light. However, wax begonias with bronze or dark leaves are bred to handle more sun. In northern climates with cooler summers, begonias can often tolerate more direct light than they can in the hot, humid South. If you plant in a sunny spot, be sure to provide plenty of water and watch for leaf scorch.
What is the best soil for begonias in the ground?
The best soil is rich in organic matter and well-draining. If your soil is heavy clay or very sandy, mix in several inches of compost or aged manure before planting. This helps the soil hold the right amount of moisture without becoming waterlogged. Aim for a soil that feels light and crumbly when you squeeze it.
Do begonias need a lot of water?
Begonias like "consistent" moisture. This means the soil should feel like a wrung-out sponge—moist but not dripping wet. You should water them whenever the top inch of soil feels dry to the touch. Avoid watering the leaves directly, as wet foliage can lead to spots or disease. Watering at the base of the plant is always the best approach. For more guidance, see this article about watering begonias in shady locations.
Can I plant begonias in the same pot as other flowers?
Yes! Begonias make excellent "thrillers" or "fillers" in mixed containers. They pair beautifully with other shade-loving plants like fuchsia, coleus, and lobelia. When choosing companions, just make sure all the plants in the pot have the same requirements for shade and moisture.
Conclusion
Finding the right spot for your begonias is the key to a season filled with beauty. By matching the variety to the light—whether it is the dappled shade of a large tree or the sheltered corner of a porch—you set the stage for success. Remember that these plants appreciate well-drained soil, protection from harsh winds, and temperatures that stay warm. Whether you are planting in garden beds or decorative containers, the effort you put into site selection will be rewarded with lush foliage and vibrant blooms.
