Introduction
There is a special kind of magic in seeing a porch or patio draped in the soft, cascading stems of a weeping begonia. These plants are famous for their "pendula" habit, which means they naturally spill over the edges of their containers in a waterfall of vibrant color. At Longfield Gardens, we love how these flowers can turn a simple shady corner into a lush, tropical-looking retreat. Because they bloom continuously from early summer right until the first frost, they are one of the most rewarding choices for any gardener looking to add long-lasting beauty to their home.
If you are wondering where to place these stunning flowers for the best results, you are in the right place. This guide will cover everything you need to know about the ideal environment for weeping begonias, from light and temperature to the best types of containers. We want to make sure your gardening experience is as enjoyable and successful as possible. By understanding a few simple rules about their preferred habitat, you can enjoy a spectacular display of flowers all season long.
With the right balance of shade, moisture, and warmth, weeping begonias will thrive in almost any space that offers protection from the harsh afternoon sun.
Understanding the Weeping Habit
To choose the best spot for your begonias, it helps to understand how they grow. Unlike upright begonias that stand tall in a garden bed, weeping begonias (often called cascading or trailing begonias) have flexible stems. As the plant grows and the flowers become heavier, the stems naturally arch downward.
Because of this growth habit, these plants grow best when they are elevated. If you plant them directly in the ground, the beautiful trailing stems will simply crawl along the soil, where the delicate flowers might get hidden by leaves or splashed with mud during rain. Placing them in a spot where they can "weep" freely allows the flowers to hang at eye level, creating a much more dramatic visual effect.
Key Takeaway: Weeping begonias are designed by nature to cascade, so they look their best when planted in containers that sit at least a few feet off the ground.
The Perfect Light Conditions
One of the most common questions we hear is whether begonias need sun or shade. The answer is a bit of both, but with a strong preference for protection. Weeping begonias are tropical at heart, and in their native environments, they grow under the canopy of trees where the light is bright but filtered. For more guidance, see this begonia sun and shade planting guide.
Morning Sun vs. Afternoon Heat
In most parts of the United States, the ideal location for a weeping begonia is a spot that receives four hours of gentle morning sun followed by shade for the rest of the day. Morning sunlight provides the energy the plant needs to produce a high volume of flowers without the intense heat that can scorch the leaves.
If you live in a northern climate with cooler summers, your begonias may be able to handle a bit more sun. However, in the South or during extreme heatwaves, even a little bit of direct afternoon sun can cause the edges of the leaves to turn brown and crispy. If you notice this happening, simply move your plant to a slightly more shaded area.
Avoiding Deep Darkness
While begonias love shade, "shade" does not mean "dark." If you place a weeping begonia in a very dark corner under a deep porch or beneath dense evergreen trees, it will likely become "leggy." This means the stems will grow long and thin as they reach for the light, and you will see fewer flowers. Look for "dappled" or "filtered" light—the kind of light that peeks through the leaves of a tall deciduous tree.
Practical Steps for Light Management:
- Observe your porch: Watch where the sun hits at 2:00 PM. If your hanging basket is in the direct line of fire, it likely needs a more sheltered spot.
- Use north or east exposures: Generally, the north and east sides of a house provide the most consistent, gentle light for these plants.
- Watch the foliage: If leaves are pale and stems are reaching, give them more light. If leaves have dry, brown patches, give them more shade.
Temperature and Climate Needs
Weeping begonias grow from tubers, and these tubers are very sensitive to the cold. Because we ship our bulbs and tubers from our facility in Lakewood, New Jersey, we track weather patterns closely to ensure your plants arrive when it is safe to plant them.
The 60-Degree Rule
The most important rule for where and when to grow begonias is the temperature of the soil and the air. Weeping begonias will sit dormant and may even rot if they are placed in cold, wet soil. We recommend waiting until the outdoor temperatures are consistently above 60°F during the day and the danger of frost has completely passed. For additional timing guidance, see when to plant tuberous begonias.
In many parts of the country, this means waiting until late May or early June to move your containers outside. If you are eager to get started, you can start your begonia tubers indoors about eight weeks before the last frost. This gives the plants a head start so they are already blooming by the time you move them to their summer home.
USDA Hardiness Zones
In USDA zones 8 through 11, begonias can sometimes stay outdoors year-round if they are protected from excessive winter rain. However, for most of the United States (zones 3 through 7), these are treated as annuals or "tender perennials." This means they will flourish all summer but must be brought inside or composted once the autumn temperatures begin to drop toward freezing. Use Longfield Gardens' hardiness zone map to check your growing zone.
Key Takeaway: Weeping begonias are warm-weather stars. Always wait for settled, warm weather before placing them in their permanent outdoor location.
Choosing the Best Containers
Because weeping begonias need elevation, the "where" usually involves a pot, basket, or box. The container you choose plays a big role in how well the plant grows.
Hanging Baskets
Hanging baskets are the classic choice for weeping begonias. They allow the stems to drape over all sides, creating a "ball" of color. When choosing a hanging basket, look for one that is at least 10 to 12 inches in diameter. This provides enough room for the roots to grow and helps the soil stay moist for longer. You can also review these tips for growing begonias in hanging baskets.
Window Boxes and Elevated Planters
If you have a window box, weeping begonias make an excellent "spiller" plant. You can plant upright flowers in the back and place the weeping begonias at the very front edge. As they grow, they will cover the front of the box with blossoms. High-quality resin or wooden planters on pedestals also work beautifully.
The Importance of Drainage
No matter what type of container you use, it must have drainage holes. "Drainage" is just a gardening word for how quickly water can escape the soil. Begonia tubers are prone to rot if they sit in a pool of water. At Longfield Gardens, we always emphasize that while begonias like to be moist, they never want to be soggy.
What to do next:
- Check your pots: Ensure there is at least one large hole in the bottom of your container.
- Use a liner: If using a wire hayrack or coco-liner basket, ensure the liner is thick enough to hold moisture but porous enough to breathe.
- Add height: If using a standard pot, place it on a plant stand or a wall to let the stems hang down.
Soil Requirements for Healthy Growth
Where a plant grows above the ground is important, but what it grows in below the ground is just as vital. Weeping begonias need a light, airy soil that doesn't pack down tightly.
Potting Mix vs. Garden Soil
We strongly recommend using a high-quality potting mix rather than soil from your yard. Yard soil is often too heavy and may contain pests or diseases that can harm the tender tubers. A good potting mix usually contains peat moss or coco coir, which holds onto just enough moisture while allowing air to reach the roots.
Enhancing Your Soil
You can improve the "where" for your plants by mixing in a little bit of compost or a slow-release fertilizer when you first plant. This provides a steady stream of nutrients that helps the plant produce those iconic cascading flowers.
- Deep watering: When you water, do it thoroughly until water runs out the bottom of the pot.
- The finger test: Before watering again, stick your finger an inch into the soil. If it feels dry, it’s time to water. If it’s still damp, wait a day.
Indoor vs. Outdoor Locations
While we usually think of weeping begonias as porch plants, they can also grow in certain indoor locations.
Growing Indoors
If you have a very bright room with a large window, you can grow weeping begonias as houseplants. However, they can be a bit fussy indoors because they crave the humidity of the outdoors. If you grow them inside, keep them away from air conditioning vents or heaters, which can dry out the air. A bathroom with a window often provides the humidity they love.
Transitioning Outdoors
Most gardeners find the best results by starting the tubers indoors on a warm windowsill in early spring and then moving the pots outside once the weather warms up. This transition should be done slowly over a few days—a process called "hardening off." Start by putting them in a shaded, protected spot for a few hours a day, gradually increasing their time outside.
Where to Plant: Step-by-Step
When you are ready to put your tubers into their final location, follow these simple steps to ensure they are positioned correctly.
- Identify the top: Begonia tubers have a "bowl" side and a rounded side. The side with the hollow or depression is the top. This is where the sprouts will emerge.
- Dig a shallow spot: You only need to cover the tuber with about one inch of soil. If you plant them too deep, they may struggle to reach the surface. See these detailed instructions for planting begonia tubers at the correct depth.
- Space them out: In a 12-inch hanging basket, you can usually fit three tubers. This will give you a very full, lush look.
- Angle for drainage: If you live in a very rainy area, you can tilt the tuber slightly so water doesn't collect in the "bowl" of the tuber, which helps prevent rot.
- Be patient: It can take 2 to 4 weeks for the first green sprouts to poke through the soil. This is a great time to practice patience and keep the soil just barely moist.
Regional Considerations
Depending on where you live in the United States, the "perfect spot" for a weeping begonia might shift slightly.
The Pacific Northwest and Northeast
In these regions, the summers are often milder. Your begonias will appreciate a spot that gets plenty of light. Because the nights can stay cool for a long time, you might find that your begonias grow a bit slower at first. Don't worry—once the "heat of the summer" hits in July, they will quickly make up for lost time.
The Southeast and Southwest
In hotter, more humid climates, shade is your best friend. The humidity in the Southeast is actually great for begonias, as it mimics their native tropical homes. However, the midday sun in the South is very intense. Aim for a spot that is almost entirely shaded from 11:00 AM to 5:00 PM. In the arid Southwest, you will need to water more frequently, as the dry air causes moisture to evaporate quickly from the leaves.
The Midwest
The biggest challenge in the Midwest is the wind. Because weeping begonias have brittle stems, a strong summer storm can occasionally snap a branch. Try to place your hanging baskets in a location that is shielded from the strongest winds, such as tucked against a porch wall or near a sturdy fence.
Key Takeaway: Match your begonia’s location to your local climate. More sun for the cool North, more shade for the hot South, and wind protection for the breezy Plains.
Feeding for Continuous Blooms
Once you have found the perfect location, you need to keep the plant "fed" so it keeps producing flowers. Because begonias in containers have a limited amount of soil, they quickly use up the available nutrients.
We suggest using a balanced, liquid fertilizer every two weeks. If you prefer a simpler routine, you can use a half-strength solution every time you water. Look for a fertilizer labeled for "flowering plants" or "blooming annuals." This ensures the plant focuses its energy on making flowers rather than just growing big green leaves.
What to Do at the End of the Season
As the days get shorter and the nights get cooler, your begonia will naturally start to slow down. When the temperatures drop below 50°F, the leaves may start to yellow. This is a sign that the plant is preparing for dormancy.
If you live in a cold climate, you have two choices. Many gardeners treat them as annuals and simply clear them out of the pots at the end of the year. However, you can also save the tubers to plant again next year. To do this:
- Stop watering and let the foliage die back naturally.
- Gently lift the tuber from the soil.
- Let it dry in a cool, dark place for a few days.
- Store it in a paper bag with some dry peat moss or sawdust in a spot that stays around 50°F (like a basement).
This cycle of growth and rest is part of what makes gardening so rewarding. There is a great deal of satisfaction in seeing the same tuber sprout and bloom even bigger the following year. For a broader overview of begonia care and overwintering, see All About Begonias.
Summary of Ideal Placement
To recap, the best place for your weeping begonias is a spot that offers:
- Elevation: Hanging baskets or window boxes to allow for cascading.
- Filtered Light: Morning sun and afternoon shade.
- Warmth: Air and soil temperatures above 60°F.
- Drainage: Potting mix that allows water to flow through easily.
- Protection: Sheltered from strong winds and heavy downpours.
By following these simple steps, you are well on your way to a season of spectacular color. Gardening should be a joy, not a chore, and choosing the right spot for your plants is the easiest way to ensure success.
Key Takeaway: Success with weeping begonias comes down to mimicking their tropical roots: give them warmth, dappled light, and a place to hang freely.

FAQ
Can I grow weeping begonias in full sun?
In most regions, full sun is too intense for weeping begonias and will likely scorch their leaves and wilt the flowers. They perform best with morning sun and afternoon shade, or under the filtered light of tall trees. If you live in a very cool, northern climate, they may tolerate more sun, but they still require consistent moisture to stay healthy.
Why are the flowers falling off my weeping begonia?
It is normal for begonias to drop their flowers as they finish blooming, but excessive dropping can be caused by heat stress or extreme soil conditions. If the soil is too dry or too wet, the plant may drop its buds as a defense mechanism. Ensure your container has good drainage and that you are watering whenever the top inch of soil feels dry.
How many tubers should I plant in a hanging basket?
For a standard 12-inch hanging basket, we recommend planting three tubers spaced evenly apart. This allows enough room for each plant's root system while ensuring the basket looks full and lush from all sides. If you are using a smaller 8-inch pot, a single tuber is usually sufficient to create a beautiful display.
Do weeping begonias need to be "deadheaded" to keep blooming?
"Deadheading" means removing the old, faded flowers to encourage new ones. While many weeping begonias are "self-cleaning" and will drop their old blossoms on their own, removing the faded flowers and any yellowing leaves can help the plant look tidier. It also prevents the plant from putting energy into seed production, which can sometimes lead to more flowers.
