Introduction
Begonias are a favorite for many gardeners because they bring incredible color and texture to the areas of the yard where many other flowers struggle. At Longfield Gardens, we want to help you find the perfect home for these tropical beauties in our All About Begonias guide. Whether you are looking to brighten a dark corner of your porch or add lush foliage to a garden bed, these versatile plants are ready to perform. We enjoy seeing how a few well-placed begonias can transform a shady spot into a vibrant oasis with very little effort.
At Longfield Gardens, we want to help you find the perfect home for these tropical beauties. While begonias are famous for being easy to grow, they do have specific preferences when it comes to their environment. Understanding their needs for light, soil, and temperature will ensure you get the most beautiful results throughout the summer season.
This guide will explain exactly where to plant your begonias to help them thrive. We will cover the best light conditions, soil requirements, and how to choose between containers and garden beds. By matching the right variety to the right location, you can enjoy a season full of spectacular blooms and stunning foliage, and the Assorted Bold Container for Shade Collection is a convenient starting point if you prefer containers.
Understanding Begonia Types and Their Needs
To answer where a begonia likes to be planted, you first need to know which type you have. The begonia family is vast, with thousands of species and hybrids. Each group has slightly different preferences for sun and space.
Tuberous Begonias
These are the showstoppers of the begonia world. They grow from tubers and produce large, rose-like flowers in brilliant shades of red, pink, yellow, and orange. Tuberous begonias, including the popular Non Stop Begonias varieties, prefer cool, shaded areas. They are excellent for hanging baskets or containers where their stems can spill over the edges.
Wax Begonias
Wax begonias are the classic bedding plants often found in parks and garden borders. They have thick, waxy leaves and clusters of small flowers. These are the most resilient of the bunch. They can handle a bit more sun than other types, especially if they have bronze-colored foliage.
Rex and Rhizomatous Begonias
These begonias are grown primarily for their breathtaking leaves. The foliage can feature swirls of silver, purple, burgundy, and emerald green. Because they are often grown as houseplants or seasonal accents, they prefer consistent shade and protection from the wind. Their delicate leaves can easily scorch if the sun is too intense.
Cane Begonias
Often called Angel Wing begonias due to their leaf shape, these plants grow tall on sturdy, bamboo-like stems. They are very adaptable and can grow in a variety of light conditions. Many people find they do exceptionally well in large floor pots on a covered patio, and Begonia Hanging Golden Balcony is a beautiful fit.
The Ideal Light Conditions
Finding the right amount of light is the most important factor in deciding where to plant your begonias. Most begonias evolved as understory plants in tropical forests. This means they are naturally adapted to dappled light and filtered shade rather than the direct, harsh glare of the midday sun.
The Beauty of Filtered Shade
Most begonias are happiest in a spot that receives bright, indirect light. Think of the light found under a tall tree with a high canopy. The leaves block the direct heat, but plenty of brightness still reaches the ground. This "bright shade" helps the plant produce flowers without burning the foliage.
Morning Sun vs. Afternoon Shade
If your garden doesn't have perfect dappled shade, look for a spot that gets morning sun and afternoon shade. The sun in the early morning (before 11:00 AM) is much cooler and less intense. Most begonias will enjoy a few hours of this gentle light. However, the hot afternoon sun can quickly wilt the stems and turn the leaf edges brown. A north-facing or east-facing side of a building is usually an ideal location. For a deeper look, see our Where to Plant Begonias: Sun or Shade? guide.
Sun-Tolerant Varieties
If you have a sunnier spot, look for wax begonias with bronze-colored leaves. The darker pigment in the foliage acts like a natural sunscreen. While they still won't enjoy a full day of 90-degree heat in the sun, they are much more durable in open garden beds than the green-leaved varieties.
Key Takeaway: When choosing a spot, prioritize afternoon shade. If the area is too dark, the plant will become leggy and produce fewer flowers. If it is too bright, the leaves may scorch. Aim for the "sweet spot" of bright, indirect light.
Soil and Drainage Requirements
Once you have identified a spot with the right light, you need to look at the soil. Begonias have a very specific "feel" they like for their roots. They want to be moist, but they never want to be soggy.
The Importance of Drainage
Drainage refers to how quickly water moves through the soil. Begonias have succulent stems and shallow roots that are prone to rot if they sit in water for too long. If you plant them in heavy clay soil that stays wet like a sponge, the tubers or roots may struggle.
To test your drainage, dig a small hole and fill it with water. If the water is still sitting there after an hour, the drainage is poor. You can improve this by adding organic matter like compost or peat moss, which helps create air pockets in the soil.
Rich, Organic Soil
Begonias are hungry plants. They perform best in soil that is rich in organic matter. This type of soil mimics the leaf litter found on a forest floor. Whether you are planting in the ground or a pot, adding a bit of compost will provide the nutrients they need to keep blooming all summer.
Choosing the Right Potting Mix
If you are planting in containers, avoid using standard garden soil. It is too heavy and can pack down too tightly. Instead, use a high-quality potting mix. These mixes are designed to be light and fluffy, allowing the roots to breathe while still holding onto the moisture the plant needs.
Environmental Factors: Temperature and Humidity
Because begonias are tropical in origin, they love warmth and moisture in the air. However, they are very sensitive to extreme temperatures.
Wait for the Warmth
One of the most common mistakes is planting begonias too early in the spring. These plants are very sensitive to cold. Even if there isn't a frost, temperatures below 50°F (10°C) can stun their growth or cause the leaves to turn yellow. We recommend waiting to move your begonias outside until the nighttime temperatures are consistently above 60°F (15°C). The soil should feel warm to the touch.
The Role of Air Circulation
While begonias like humidity, they also need fresh air. If they are planted in a very crowded, stagnant spot, they can develop fungal issues like powdery mildew. This looks like a white dust on the leaves. To prevent this, give your plants a little bit of "breathing room" by following the recommended spacing on the plant tag.
Planting Locations: Containers, Beds, and Baskets
The physical location you choose—whether it is a hanging basket, a window box, or a garden bed—will affect how much care the plant needs.
Hanging Baskets and Window Boxes
Trailing tuberous begonias are especially at home here, and the Hanging Begonias collection is a natural fit. When planted in a basket, the flowers will gracefully cascade over the side. Because baskets are elevated, they tend to dry out faster than the ground. This can actually be a benefit for begonias, as it prevents the soil from staying too soggy. Just be sure to check the moisture levels daily during the height of summer.
Garden Borders and Beds
Wax begonias and upright tuberous varieties like the Upright Double Begonias look wonderful when massed together in a border. They create a consistent carpet of color. When planting in the ground, choose a spot that is slightly elevated or sloped to ensure that heavy rain doesn't pool around the base of the plants.
Under Trees and Large Shrubs
This is a natural habitat for begonias, but there is one thing to watch out for: root competition. Large trees have big roots that can soak up all the water and nutrients before the smaller begonias can get any. If you plant under a tree, you may need to water and fertilize a little more frequently to make sure your begonias aren't going hungry. For more ideas on using shade effectively, see our Design Tips for Shady Gardens.
Practical Planting Steps for Success
Getting the depth and spacing right is a simple win that makes a big difference in how your begonias grow.
Spacing for Growth
It is tempting to plant begonias close together for an instant look of fullness. However, they will grow quickly once the weather warms up.
- Wax Begonias: Space these about 6 to 8 inches apart.
- Tuberous Begonias: Space these 8 to 12 inches apart.
- Large Cane Begonias: These may need 15 to 18 inches of space.
Planting Depth for Tubers
If you are starting with tuberous begonias from Longfield Gardens, you will notice the tubers have a slightly indented or hollow side. This is the top! For a deeper look at exact depth, see How Deep Should I Plant Begonia Tubers?.
- Dig a shallow hole.
- Place the tuber with the hollow side facing up.
- Cover it with only about an inch of soil.
- Do not bury them too deep, as the sprouts need to reach the surface easily.
What to Do Next
- Check your zone: Begonias are tender perennials (Zones 9–11) but are grown as annuals elsewhere. Hardiness Zone Map
- Prepare the spot: Mix in a handful of compost before planting.
- Watch the weather: Keep plants indoors until the nights stay warm.
- Water in: Give them a gentle drink immediately after planting to settle the soil.
Maintaining Your Begonias in Their New Home
Once you have found the perfect spot, a little bit of routine care will keep them looking their best.
Watering Correctly, Not Constantly
The "touch test" is the best way to know when to water. Stick your finger an inch into the soil. If it feels dry, it is time to water. If it feels moist, wait another day. When you do water, try to aim for the base of the plant. Wetting the leaves can sometimes lead to spots or fungal issues, especially in humid climates. For more details, see How Much Water Does a Begonia Plant Need?.
Feeding Your Plants
Begonias put a lot of energy into making flowers and lush leaves. To support this, they appreciate a regular supply of nutrients. You can use a balanced, water-soluble fertilizer about once every two to four weeks. Follow the instructions on the label for the correct amount. If you notice your plants have lots of green leaves but no flowers, you might be using too much nitrogen. A "bloom booster" formula can help encourage more blossoms.
Deadheading
Most modern begonias are "self-cleaning." This means the old flowers will fall off on their own as they fade. You don't have to spend hours pinching off dead blooms. However, if you see spent flowers sitting on the leaves, it is a good idea to brush them away. This keeps the plant tidy and prevents old petals from rotting on the foliage.
Design Ideas for Begonias
Begonias are team players in the garden. They play well with other plants that share their love for shade and moist soil.
Texture Combinations
Because many begonias have bold, fleshy leaves, they look fantastic when paired with plants that have fine or airy textures. For more pairing ideas, see our What Plants Grow Well With Begonias? guide.
- Ferns: The delicate fronds of a fern provide a soft backdrop for the large, colorful blooms of a tuberous begonia.
- Ornamental Grasses: Shade-loving grasses like Hakonechloa (Japanese Forest Grass) add movement and a different leaf shape to the arrangement.
Color Echoing
Try matching the color of your begonia flowers to the variegation in nearby foliage. For example, a white-flowering begonia looks stunning next to a hosta with white-edged leaves. A pink begonia can pick up the pink tones in the leaves of a caladium or a coleus.
Creating a Focal Point
A large, ornate container filled with a single type of begonia can serve as a beautiful focal point on a porch, and Begonia Upright Double Roseform Pink is a classic choice. We often recommend using a "Thriller, Filler, Spiller" approach. An upright cane begonia makes a great "thriller" in the center, while smaller wax begonias act as "fillers," and trailing begonias serve as the "spiller" over the edges.
Transitioning with the Seasons
As the summer winds down, you have a choice to make depending on where you live.
Bringing Them Indoors
If you have a favorite rex or cane begonia, you can bring it inside to live as a houseplant during the winter. Move it inside before the temperatures drop below 50°F. Place it in a bright window, but away from any cold drafts or heater vents. Reduce your watering, as the plant will grow more slowly in the winter months.
Storing Tubers for Next Year
Tuberous begonias can be saved and replanted next spring. When the leaves start to yellow in the autumn, stop watering and let the plant die back. Once the foliage is brown, dig up the tubers. Shake off the excess soil and let them dry in a cool, dark place for a few days. You can then store them in a box of peat moss or sawdust in a basement or closet where they won't freeze.
Starting Fresh
Many gardeners prefer to treat begonias as a seasonal treat and start with fresh, high-quality tubers or plants each spring. This allows you to try new colors and varieties every year without the need for winter storage space.
Summary of Success
Finding the right place for your begonias doesn't have to be complicated. If you remember these few basic rules, you will be well on your way to a beautiful display.

FAQ
Can begonias grow in full sun?
Most begonias prefer shade or filtered light, but wax begonias with bronze-colored leaves are more tolerant of the sun. In northern climates with cooler summers, they can handle more direct light than they can in the hot, humid south. Always provide afternoon shade in very hot regions to prevent the plants from wilting.
Why are my begonia leaves turning yellow?
Yellow leaves are often a sign of too much water or soil that doesn't drain well. Begonias like to stay moist but never soggy. Check the soil with your finger; if it feels very wet, allow it to dry out a bit before watering again. Yellowing can also happen if the temperatures drop below 50°F at night.
Do I need to remove dead flowers from my begonias?
Most modern begonias, such as the wax and Non-Stop varieties, are self-cleaning and do not require deadheading to keep blooming. However, removing spent blooms can help the plant look tidier and prevents old petals from sticking to the leaves, which can sometimes lead to fungal spots in humid weather.
Can I plant begonias in the same spot every year?
Yes, you can plant begonias in the same garden bed or container each year. However, it is a good idea to refresh the soil with some new compost or fresh potting mix each season. This replenishes the nutrients and helps maintain the light, airy soil structure that begonias love.
