Choosing the Best Begonias for Your Basket
Before you start digging, it is important to choose the right type of begonia for a hanging display. While all begonias are beautiful, they have different growth habits. Some grow straight up, while others are born to tumble over the edges of a container.
Trailing vs. Upright Varieties
For hanging baskets, "pendula" or trailing begonias are the most popular choice. These varieties have flexible stems that naturally arch downward as they grow. This creates a waterfall of flowers that covers the sides of the basket. Varieties like the 'Cascade' series or 'Pendula' types are specifically bred for this purpose.
Upright begonias can also work in baskets, especially if you want a fuller look in the center. Many gardeners choose to mix one upright variety in the middle with several trailing types around the edges. This creates a rounded, "mound" effect that looks beautiful from every angle.
Exploring Flower Shapes and Colors
Begonias offer an incredible range of flower forms. You might choose the large, rose-like blooms of the 'Double' varieties for a classic look. If you prefer something more delicate, the single-flowered types like 'Bertini' offer a more airy, graceful appearance.
Color is where you can really have fun. You can stick to a monochromatic theme with elegant 'Pendula White' or go bold with a mix of fiery reds and oranges. Because begonias thrive in partial shade, their bright colors often look even more luminous against the darker corners of a porch or patio.
Key Takeaway: For the most dramatic hanging display, look for varieties labeled "trailing" or "pendula." These plants are naturally inclined to cascade over the sides of your container.
When to Start Your Begonia Tubers
Timing is everything when it comes to begonias. These are tropical plants that love warmth and are very sensitive to the cold. To get the longest possible blooming season, it is best to give your tubers a head start indoors.
The Benefits of Pre-Sprouting
In most parts of the United States, the growing season isn't quite long enough for begonias to reach their full potential if you wait until the last frost to plant them outside. By starting them indoors about 8 to 12 weeks before the last expected frost, you ensure the plants are well-established and ready to bloom by early summer.
Starting indoors also allows you to monitor the tubers as they wake up. You can ensure they stay at the right temperature and moisture level before they have to face the changing conditions of the outdoors.
Understanding Your Planting Zone
While we ship our tubers according to your specific USDA hardiness zone, the actual date you move your baskets outside depends on your local weather. For shipping timing and zone-based scheduling, see our Shipping Information. Begonias prefer night temperatures to be consistently above 50°F. If you live in a cooler climate, you might wait until late May or early June to hang your baskets permanently.
- Check your local frost dates: Use a reliable weather guide to find the average last frost date for your zip code.
- Watch the thermometer: Even after the frost date, keep an eye on night temperatures.
- Be patient: Moving them out too early can stall their growth, so it is better to wait for a warm week.
Preparing Your Hanging Basket and Soil
The foundation of a great hanging basket is the container and the soil inside it. Because begonias will spend the entire season in this environment, it is worth spending a few extra minutes to get the setup right.
Selecting the Right Container
Hanging baskets come in many materials, including plastic, ceramic, and wire with coir (coconut fiber) liners. Wire baskets with coir liners are excellent for begonias because they provide superior drainage and allow the roots to breathe.
If you choose a plastic or ceramic pot, ensure it has at least one large drainage hole at the bottom. Begonias do not like to sit in "wet feet," which can cause the tubers to rot. Good drainage is the most important factor in keeping your plants healthy.
The Ideal Potting Mix
Never use standard garden soil in a hanging basket. It is too heavy and can compress, cutting off oxygen to the roots. Instead, use a high-quality, peat-based potting mix. Look for a mix that is labeled as "humus-rich" or designed specifically for containers.
A good potting mix should be light and fluffy. It often contains perlite or vermiculite (the little white or shiny flecks) to help with aeration and moisture retention. Before planting, you can mix in a small amount of slow-release fertilizer pellets to provide a steady supply of nutrients as the plants grow.
Key Takeaway: Use a lightweight, peat-based potting mix and a container with excellent drainage. This prevents soil compaction and keeps the tubers from getting too wet.
How to Plant Begonia Tubers Step-by-Step
Once your tubers have arrived and you have your supplies ready, it is time to plant. Begonia tubers have a unique shape that can be a little confusing at first, but a quick look will tell you exactly which way is up.
Identifying the Top of the Tuber
A begonia tuber looks like a small, brown, slightly fuzzy disk or bowl. One side is indented or "cupped," and the other side is rounded. The cupped or concave side is the top. This is where the sprouts will emerge. The rounded side is the bottom, where the roots will grow.
If your tubers have already started to sprout, you might see small, pinkish-red buds in the center of the "bowl." This is a great sign that the tuber is healthy and ready to grow.
Planting Depth and Spacing
When planting in a hanging basket, you want to give the tubers enough room to grow without overcrowding them. For a standard 12-inch hanging basket, three to four tubers are usually sufficient to create a full, lush look.
- Fill the basket: Fill your container with potting mix until it is about 2 inches below the rim.
- Create indents: Use your fingers to make shallow depressions in the soil about 1 inch deep.
- Place the tubers: Set the tubers into the indents with the cupped side facing up.
- Cover lightly: Cover the tubers with about 1 inch of potting mix. Do not pack the soil down too hard; a gentle firming with your palm is enough.
- Water sparingly: Give them a light drink to settle the soil.
Initial Care Indoors
Keep your newly planted basket in a warm spot (around 70°F) with bright, indirect light. A windowsill that doesn't get harsh, direct afternoon sun is perfect. During this stage, be very careful not to overwater. The soil should be slightly moist, like a wrung-out sponge, but never soggy. You likely won't need to water again until you see the first green leaves poking through the soil.
Moving Your Baskets Outdoors
As the weather warms up, your begonias will be eager to get outside. However, jumping straight from a cozy indoor environment to the variable outdoor air can be a shock. A process called "hardening off" helps them adjust safely.
The Hardening Off Process
Hardening off simply means giving your plants a little bit of outdoor exposure at a time. This toughens the leaves and stems so they can handle wind and direct sunlight.
- Day 1-2: Place the basket in a shaded, sheltered spot outside for 2-3 hours, then bring it back inside.
- Day 3-4: Increase the time to 5-6 hours, still avoiding direct afternoon sun.
- Day 5-7: Leave the basket out all day. Bring it in only if the night temperature is forecasted to drop below 50°F.
- Final Step: Once the nights are consistently warm, you can hang your basket in its permanent location.
Finding the Perfect Spot
Begonias are famous for their love of shade, but they do need some light to produce those massive blooms. The best location is one that receives "filtered" light or gentle morning sun.
The hot, intense sun of the mid-afternoon can scorch the delicate leaves and cause the flowers to wilt. An east-facing porch or the dappled shade under a large tree is usually ideal. If you notice the leaves looking pale or yellow, they might be getting too much sun. If the stems are getting very long and "leggy" with few flowers, they might need a bit more light.
Key Takeaway: Gradually introduce your begonias to the outdoors over the course of a week. Once hardened off, hang them in a spot with filtered light or morning sun for the best results.
Essential Care for Summer Blooms
Once your begonias are settled in their outdoor home, a simple maintenance routine will keep them blooming beautifully until the first frost. Hanging baskets dry out much faster than garden beds, so watering is your most important task.
Mastering the Watering Routine
The goal with begonias is consistent moisture without waterlogging. During the heat of summer, you may need to water your hanging baskets every day. However, always check the soil first. Stick your finger about an inch into the potting mix; if it feels dry, it is time to water.
When you water, try to aim for the soil rather than the leaves or the center of the tuber. Water sitting in the "cup" of the tuber can lead to rot. Water thoroughly until you see it running out of the drainage holes at the bottom of the basket. This ensures the entire root system gets a drink and helps flush out any built-up salts from fertilizers.
Feeding for Maximum Flowers
Begonias are "heavy feeders," meaning they need plenty of nutrients to keep producing those large, showy flowers. Once the plants have several sets of leaves and are actively growing, start a regular fertilizing schedule.
A water-soluble fertilizer with a high potassium content (often marketed as "bloom booster" or tomato fertilizer) works wonders. Apply the fertilizer at half or quarter strength every time you water, or at full strength once a week. This steady supply of food will ensure the plant has the energy to keep blooming all season long.
Cleaning Up and Deadheading
Begonias are generally "self-cleaning," meaning the old flowers will eventually fall off on their own. However, removing spent blooms and any yellowing leaves manually will keep the basket looking tidy and can help prevent mold or fungus.
If your trailing begonias start to look a bit too long or sparse, don't be afraid to pinch back the tips of the stems. This encourages the plant to branch out, resulting in a fuller, bushier basket with even more flower sites.
Action Plan for Summer Care:
- Check soil moisture daily by touching the top inch of mix.
- Water the soil directly, avoiding the foliage and tuber center.
- Feed weekly with a liquid "bloom booster" fertilizer.
- Remove wilted flowers and yellow leaves to keep the display fresh.
Creative Ways to Style Begonia Baskets
While a basket full of a single begonia variety is stunning, you can also experiment with mixed plantings. Begonias play well with other shade-loving plants, allowing you to create complex textures and color palettes.
Mixing Textures and Colors
Consider pairing trailing begonias with plants that have interesting foliage. The lime-green leaves of 'Creeping Jenny' or the silvery trails of 'Dichondra Silver Falls' provide a beautiful contrast to the deep green or bronze leaves of many begonias.
If you want more flowers, look for companions that share the same light and water requirements.
- Fuchsia: These also love shade and have a beautiful pendulous habit.
- Lobelia: Their tiny blue or white flowers fill in the gaps between larger begonia blooms.
- Bacopa: A classic "filler" plant that produces a cloud of small, delicate flowers.
Playing with Heights
If you have a large porch, try hanging your baskets at different heights. This creates a "wall of color" effect that feels very immersive. You can also use shepherd’s hooks of varying sizes in a garden bed to create focal points at eye level.
Because begonias are so vibrant, they work well as a "welcome" display. Hanging a pair of matching baskets on either side of a front door creates an instant sense of symmetry and curb appeal.
Protecting Your Baskets from Wind and Weather
Tuberous begonias have somewhat brittle stems, especially the varieties with very large, heavy flowers. Strong winds can occasionally snap a stem, so it is helpful to provide a bit of protection.
Strategic Placement
If you live in an area prone to summer thunderstorms or high winds, hang your baskets in a somewhat sheltered spot. A porch with a roof or a location tucked against a wall provides a natural windbreak.
For upright begonias in large containers, you can use small bamboo stakes and soft plant ties to support the main stems. This isn't usually necessary for trailing types in baskets, as their weight is distributed more evenly over the sides.
Handling Extreme Heat
While begonias love warmth, extreme heat (above 90°F) can cause them to go into a temporary resting phase. During a heatwave, you might notice fewer flowers or some wilting.
To help them through, ensure they stay well-watered and consider moving the baskets to a deeper shade area until the temperature drops. Misting the air around the baskets (not the plants themselves) can also help lower the immediate temperature through evaporation.
Transitioning to Dormancy
As the summer fades and the first hints of autumn arrive, your begonias will naturally begin to slow down. One of the best things about tuberous begonias is that you can save the tubers and grow them again next year.
Preparing for Storage
When the leaves start to turn yellow and the plant stops producing new buds, it is time to prepare for dormancy. This usually happens after the first light frost, which will blacken the foliage.
- Stop watering: Allow the soil to dry out completely.
- Trim the stems: Once the stems have withered, they should pull away easily from the tuber. If they don't, cut them back to about an inch above the tuber.
- Lift and clean: Carefully remove the tubers from the basket. Gently brush off any excess soil, but do not wash them with water.
- Cure: Let the tubers sit in a dry, room-temperature spot for a few days to "cure" the outer skin.
Winter Storage Tips
Store your tubers in a cool, dark, and frost-free place. A basement or a cool closet is usually perfect. Place them in a paper bag or a box filled with dry peat moss or sawdust. This keeps them dry while providing a little bit of insulation.
Check on them once or twice during the winter to make sure they aren't shriveling up or showing signs of mold. If they look very shriveled, you can give the peat moss a tiny mist of water. Then, when spring rolls around, you can start the whole process over again!
Key Takeaway: Begonias can be enjoyed year after year. Store the dry tubers in a cool, dark place over winter and replant them when the spring warmth returns.

FAQ
Which way do I plant a begonia tuber?
Begonia tubers have a distinct "cupped" or indented side and a rounded side. Always plant them with the cupped side facing up, as this is where the new stems will grow. If you see small red buds, those are the sprouts, and they should point toward the sky.
How many begonia tubers should I put in one hanging basket?
For a standard 10-inch to 12-inch hanging basket, planting three to four tubers is ideal. This provides enough space for each plant's roots to grow while ensuring the basket looks full and overflowing once the plants reach maturity. For more detail on spacing, see our Can Begonias Grow in Hanging Baskets? guide.
Do begonias in hanging baskets need full sun?
No, tuberous begonias actually prefer partial shade or filtered sunlight. While they need some light to bloom well, direct afternoon sun can be too intense and may scorch their leaves. An east-facing spot that gets morning sun and afternoon shade is perfect.
How often should I fertilize my hanging begonias?
To keep begonias blooming vigorously, it is best to fertilize them once a week with a water-soluble, high-potassium fertilizer. Alternatively, you can use a diluted strength every time you water. This provides a steady stream of nutrients to support their heavy blooming habit.
