Introduction
Imagine stepping onto your porch or into a quiet corner of your yard and being greeted by a lush wall of color. Begonias are one of the most rewarding plants for home gardeners because they bring vibrant flowers and stunning foliage to the spots where many other plants struggle to grow. Whether you are looking for the rose-like blooms of tuberous varieties or the waxy, reliable color of bedding types, finding the perfect home for these plants is the first step toward a beautiful season.
At Longfield Gardens, we enjoy helping gardeners find the right begonias for their unique spaces. Begonias are incredibly versatile, but they do have specific preferences when it comes to light, soil, and shelter.
How to Plant and Care for Begonias will help you identify the best locations in your yard or home to ensure your plants thrive from the moment you tuck them into the ground or a pot.
Knowing where to plant your begonias allows you to take advantage of their natural strengths. This article covers how to evaluate your light levels, identify the best soil conditions, and choose locations that protect your plants from the elements. By matching your begonia variety to the right environment, you can enjoy a season of effortless beauty.
Understanding Light Requirements
The most common question gardeners ask is whether begonias need sun or shade. The answer depends almost entirely on the specific variety you choose. Are Begonias Shade or Sun Plants? can help you decide what your space offers.
Part Shade to Dappled Light
Most begonias, especially the large-flowered tuberous varieties, prefer a location with partial shade. This usually means a spot that receives four to six hours of indirect light or filtered sunlight. Think of the light found under a tall tree with a high canopy. The sunlight "dapples" through the leaves, providing brightness without the intense heat of direct rays.
If you plant tuberous begonias in a spot that is too dark, they may grow leggy as they reach for the light, and they will produce fewer flowers. Conversely, if the light is too intense, the delicate petals and succulent leaves can scorch. A north-facing or east-facing location is often the "sweet spot" for these plants, as they get the gentle morning sun but are protected during the harshest part of the afternoon.
Full Shade for Foliage
If you have a corner that receives very little direct sunlight—perhaps under a covered porch or in a deep nook between buildings—focus on foliage begonias like the Rex or Rhizomatous types. These varieties are prized for their spectacular leaves, which can feature swirls of silver, purple, and deep green. Because they are not working hard to produce massive blooms, they are much more tolerant of lower light levels. While they still need some light to maintain their vibrant colors, they can handle the deeper shade where most flowering annuals would fail.
Sun-Tolerant Options
Some begonias are bred to handle more sun than their cousins. Wax begonias, often used as bedding plants, are quite resilient. If you have a spot that gets more than six hours of sun, look for varieties with bronze-colored foliage. The darker pigment in the leaves acts like a natural sunscreen, protecting the plant from burning. Even these sun-tolerant types appreciate some afternoon relief if you live in a particularly hot climate.
What to do next:
- Observe your garden for a full day to see which areas get morning sun versus afternoon sun.
- Identify "bright shade" spots, such as north-facing walls or under airy trees.
- Check your plant tags to see if your variety is light-sensitive or sun-tolerant.
The Importance of Soil and Drainage
Once you have found a spot with the right light, the next factor in deciding where to plant is the soil. Begonias have thick, succulent stems that hold a lot of water. This makes them somewhat drought-tolerant, but it also makes them very sensitive to "wet feet."
Avoiding Soggy Spots
You should never plant begonias in a low-lying area where water tends to collect after a rainstorm. If the soil remains soggy for long periods, the stems or tubers can rot quickly. When scouting for a location, look for areas where the water drains away easily. If you have heavy clay soil that stays wet, consider planting in raised beds or containers where you can control the drainage more effectively.
Rich, Loamy Soil
Begonias are heavy feeders because they bloom continuously for months. They prefer soil that is rich in organic matter. A loamy soil that is light and fluffy allows the roots to spread easily while also holding onto just enough moisture to keep the plant hydrated. If your garden soil feels hard or "dead," you can improve the site by mixing in a few inches of compost or well-rotted leaf mulch before planting. This creates the aerated environment that begonias love.
PH Balance
Most begonias prefer a slightly acidic to neutral soil pH, typically between 5.5 and 6.5. Most standard garden soils fall into this range, but if you are planting in an area near a concrete foundation, the soil may be more alkaline. Amending the area with peat moss or high-quality potting mix can help bring the pH down to a level that keeps the plants happy.
Choosing Locations Based on Begonia Type
Not all begonias grow the same way. Some stand tall and upright, while others trail gracefully over the edges of pots. Matching the growth habit to the location is key to a professional-looking garden.
Tuberous Begonias in Containers and Baskets
Tuberous begonias, such as the Non Stop Begonias, produce large, heavy blooms that often look like roses or camellias. Because the flowers are so large, they can sometimes weigh down the stems. These are perfect for containers or window boxes placed at eye level where you can appreciate the intricate details of the blooms.
Trailing tuberous begonias, often labeled as "Pendula," are the best choice for hanging baskets. These hanging begonias should be placed in sheltered locations like a porch ceiling or a bracket on a shaded fence. In these spots, the flowers can cascade downward without being damaged by wind.
Wax Begonias for Borders and Mass Plantings
If you are looking to fill a large area in the landscape, wax begonias are the way to go. These plants stay relatively compact, usually between 6 and 12 inches tall. They are excellent for edging a walkway or creating a "carpet" of color under a shade tree. Because they are uniform in height, they provide a clean, organized look to the front of a garden bed.
Cane Begonias as Focal Points
Cane-type begonias, including the popular Angel Wing varieties, grow upright on sturdy, bamboo-like stems. These can get quite tall, sometimes reaching several feet in a single season. They make excellent focal points in the center of a large planter or at the back of a shaded border. Because they grow vertically, they are great for adding height to a space without taking up too much horizontal room.
Microclimates: Wind and Heat
A "microclimate" is a small area where the conditions differ from the rest of the yard. When deciding where to plant begonias, these small details can make a big difference in the plant's health.
Protection from Wind
Begonias have brittle stems that can snap easily in a strong gust. This is especially true for the large-leaved Rex varieties and the heavy-flowering tuberous types. Avoid planting them in wide-open, unsheltered areas or in "wind tunnels" between houses. A location near a fence, a wall, or surrounded by other sturdier plants will provide the windbreak they need to stay intact. For more care tips, see Tips for Growing Tuberous Begonias.
Avoiding Radiant Heat
While begonias like warmth, they do not like to be baked. Avoid planting them directly against a dark-colored brick wall that faces the afternoon sun. These walls absorb heat all day and radiate it back onto the plants, even after the sun goes down. This can cause the soil to dry out too fast and stress the plant. If you want to plant near a wall, choose an east-facing side that stays cool in the afternoon.
Humidity and Airflow
As tropical plants, begonias enjoy a certain amount of humidity. However, they also need good airflow to prevent fungal issues like powdery mildew. Avoid "stuffing" begonias into a crowded corner with no air movement. A spot with a gentle breeze that is still sheltered from strong winds is the ideal compromise.
What to do next:
- Identify areas in your yard that are naturally protected from the wind.
- Feel the temperature of your home's exterior walls in the evening to check for radiant heat.
- Space your plants according to the instructions on the tag to ensure enough air can circulate between them.
Planting in the Landscape vs. Containers
Where you plant often dictates how you plant. Both in-ground beds and containers offer unique benefits for begonias.
Landscape Planting
Planting begonias directly in the ground is a great way to create a lush, permanent look for the summer. This is best for wax begonias or Surefire varieties that are vigorous and can handle the variability of garden soil.
- Site Preparation: Loosen the soil to a depth of at least 6 inches.
- Moisture Management: Mulch the area with a thin layer of fine bark or compost to keep the soil temperature even and prevent moisture from evaporating too quickly.
- Proximity: Plant them close enough together that they will touch when mature, creating a solid mass of color that shades the soil and keeps the roots cool.
Container Planting
Containers are the most popular way to grow begonias because they allow you to move the plants to find the perfect light. Container-friendly begonias are especially useful if a spot proves to be too sunny.
- Potting Mix: Always use a high-quality, lightweight potting soil rather than garden soil. This ensures the drainage is perfect.
- Drainage Holes: Ensure your pot has plenty of holes in the bottom. If you have a decorative pot without holes, use it as a "cachepot"—place the begonia in a plastic nursery liner with holes and set that inside the pretty container.
- Placement Flexibility: Containers are perfect for brightening up steps, patios, and balconies where there is no soil for planting.
Timing Your Planting
Where you plant is only half the battle; when you plant is just as important. Begonias are very sensitive to the cold. They are tropical in nature and will stop growing or even suffer damage if temperatures dip below 50°F.
Wait for the Warmth
In most regions, it is best to wait until the danger of frost has completely passed and the soil has warmed up to at least 60°F. If you plant too early in a cold, damp spot, the plants will simply sit there and may succumb to rot before they ever get a chance to grow.

Starting Indoors
If you live in a northern climate with a short growing season, you can start your begonia tubers indoors about 8 weeks before the last frost. How to Start Tuberous Begonias Indoors covers the basics. This allows you to "wake them up" in a controlled environment. Once the weather is consistently warm, you can move the pots to their permanent outdoor locations. This gives you a head start on blooms, often resulting in flowers weeks earlier than if you had started them directly outside.
Solving Landscape Problems with Begonias
Begonias are not just pretty faces; they are problem-solvers in the garden. You can use them strategically to improve the look of difficult areas.
Brightening Dark Corners
The "white" and "yellow" varieties of begonias are like little lightbulbs for the shade. If you have a dark corner of the yard that looks gloomy, planting light-colored begonias will reflect what little light is available and make the area feel more inviting.
Softening Hard Lines
The trailing nature of many begonias is perfect for softening the hard edges of stone walls or concrete planters. By planting trailing varieties along the top of a retaining wall, you create a living curtain that blends the structural elements of your yard with the natural ones.
Filling Gaps in Perennial Beds
In mid-summer, many early-blooming perennials like bleeding hearts or lungwort begin to go dormant or look a bit tired. Begonias are excellent "fill-ins." Since they don't mind a bit of shade from taller surrounding plants, you can tuck them into these gaps to keep the garden looking full and colorful until autumn.
Indoor Placement for Begonias
Many gardeners forget that begonias make excellent houseplants. In fact, Rex begonias and many cane-type begonias are often happier indoors where the climate is stable. Are Begonias Inside or Outside Plants? explains when each situation makes the most sense.
Bright, Indirect Light
Inside the home, the best place for a begonia is near a bright window that does not receive direct sun. A north or east-facing window is ideal. If you have a south-facing window, place the plant a few feet back from the glass or use a sheer curtain to filter the light.
Avoid Drafts
Just like their outdoor counterparts, indoor begonias dislike extreme temperature changes. Avoid placing them directly in the path of an air conditioning vent or a heating radiator. They prefer a consistent temperature and a bit of extra humidity, which you can provide by placing the pot on a tray of pebbles filled with water.
Moving Outdoors and Back
If you choose to move your indoor begonias outside for the summer, do it gradually. Start by placing them in a very shaded, protected spot for a few hours a day, slowly increasing their exposure to the outdoors. This "hardening off" process prevents the leaves from shocking and dropping. We recommend bringing them back inside before the night temperatures drop into the 50s in the fall.
Summary of Best Placement Practices
Choosing the right spot for your begonias doesn't have to be complicated. If you follow a few basic rules, your plants will reward you with beauty all season long.
- Match variety to light: Wax begonias for sunnier spots, Rex for deep shade, and Tuberous for dappled light.
- Prioritize drainage: Never plant in a spot where water pools.
- Seek shelter: Protect delicate stems from strong winds and heavy rain.
- Think about height: Use trailing types for baskets and upright types for borders.
- Wait for warmth: Only move begonias outside when the weather is reliably warm.
Key Takeaway for Success: The best location for most begonias is a spot with "bright shade"—where there is plenty of light for the plant to see, but no direct sun to burn the leaves. Ensuring the soil is rich and well-drained will do more for your plants than any special fertilizer ever could.

FAQ
Can begonias grow in full sun?
Most begonias prefer shade or filtered light, but certain varieties like wax begonias (especially those with bronze leaves) can tolerate full sun in cooler climates. However, in very hot regions, even sun-tolerant begonias usually need some protection from the intense afternoon heat to prevent leaf scorch.
What happens if I plant my begonias in a spot that is too dark?
If a begonia doesn't get enough light, it will become "leggy," meaning the stems grow long, thin, and weak as they stretch toward the nearest light source. You will also notice significantly fewer flowers, and the colors of the foliage may appear dull or faded compared to plants in brighter spots.
Is it better to plant begonias in the ground or in pots?
Both options work well depending on your soil. If your garden soil is heavy clay or doesn't drain well, Can You Plant Begonias Outside? explains why pots are often better because they allow you to use a high-quality potting mix and control moisture. Pots also allow you to move the plants around to find the perfect light as the seasons change.
Should I plant my begonias near other plants?
Yes, begonias make excellent companions for other shade-loving plants like hostas, ferns, and caladiums. When planting them together, just make sure to give each plant enough space for air to circulate, which helps prevent common issues like powdery mildew or fungal leaf spots.
