Introduction
Finding the perfect flower for those quiet, shaded corners of the yard is a highlight of the spring planning season. Whether you have a covered porch or a garden bed tucked under an old oak tree, begonias offer a splash of color that few other plants can match. At Longfield Gardens, we enjoy helping people discover that these tropical beauties are far simpler to care for than their exotic looks might suggest.
This guide is designed for home gardeners who want to bring vibrant blooms and lush foliage into their landscape without a lot of fuss. We will cover how to select the best varieties, where to plant them for the most success, and the simple care routines that keep them blooming until the first frost. Most begonias are remarkably resilient if you get a few basic steps right. For a deeper look at the plant, see our All About Begonias guide.
Choosing the right variety and following a few simple planting rules makes a begonia easy to grow for gardeners of every skill level.
Choosing the Best Easy to Grow Begonias
The first step in garden success is matching the right plant to your specific goals. Begonias come in several different forms, and each has its own strengths. While some are grown primarily for their flowers, others are prized for their dramatic, patterned leaves. Understanding these differences helps you pick the variety that will thrive best in your space.
Tuberous Begonias for Maximum Color
Tuberous begonias are the stars of the shade garden. They grow from a thickened underground stem called a tuber, which stores energy for the plant. This makes them very dependable because the plant already has the fuel it needs to start growing. They produce large, often double-petaled flowers that look like roses or camellias.
Varieties such as the Nonstop series are particularly popular because they bloom early and continue consistently throughout the summer. These are excellent for garden borders and window boxes. If you are looking for something to spill over the sides of a hanging basket, trailing tuberous begonias like the Golden Balcony or Pink Balcony series are wonderful choices.
Wax Begonias for All-Day Resilience
If you need a plant that is virtually indestructible, wax begonias are a top choice. These are often used as bedding plants in large landscapes because they handle varying conditions so well. They have glossy, succulent-like leaves that help them retain moisture. While most begonias prefer shade, many wax varieties can handle a surprising amount of sun if they receive enough water.
Rex Begonias for Foliage Lovers
Rex begonias are famous for their "painted" leaves. Instead of focusing on flowers, these plants show off swirls of silver, purple, pink, and deep green. They are often grown as houseplants, but they make fantastic additions to outdoor containers in the summer. They bring texture and visual interest to areas where other flowers might struggle to bloom.
Key Takeaway To make your garden successful, match the begonia type to your container or bed. Use trailing types for baskets and upright, tuberous types for garden borders.
Finding the Best Spot: Right Plant, Right Place
Success with begonias starts with where you put them. These plants are native to tropical and subtropical climates, which gives us a clue about what they like. They prefer warmth and filtered light. If you put a shade-loving begonia in the harsh afternoon sun, the leaves may scorch. Conversely, putting them in deep, dark shade may result in fewer flowers. If you are unsure about your area, the Hardiness Zone Map can help you confirm your growing zone.
Understanding Light Requirements
Most begonias thrive in "dappled" or "filtered" sunlight. This is the kind of light you find under a leafy tree or on a porch that gets morning sun but is shaded in the afternoon.
- Morning Sun: The gentle light before noon is ideal for almost all varieties.
- Dappled Shade: Light that filters through tree branches provides the perfect balance of energy and protection.
- Full Shade: While they will grow here, you may see more foliage and fewer blooms.
The Importance of Drainage
"Drainage" refers to how fast water leaves the soil. Begonias have fleshy stems and roots that store water. If the soil stays too wet for too long, the roots can struggle to breathe and may eventually rot.
To check your drainage, watch your garden after a heavy rain. If water puddles in a spot for more than five or six hours, that area is likely too wet for begonias. For these spots, consider using a raised bed or a container filled with high-quality potting mix. Potting mix is designed to be "well-draining," meaning it holds enough moisture for the plant but lets the excess flow out.
How to Plant Begonia Tubers
Planting tubers is one of the easiest ways to start your garden. Unlike tiny seeds that require constant attention, a tuber is a sturdy starting point. We recommend starting your tubers indoors about six to eight weeks before the last frost date in your area. This gives the plants a "head start" so they are ready to bloom as soon as the weather warms up. For step-by-step planting help, see Tips for Growing Tuberous Begonias.
Identifying the Top and Bottom
When you look at a begonia tuber, you will notice one side is slightly indented or hollowed out, like a small bowl. This is the top. The smooth, rounded side is the bottom. The stems and leaves will grow out of the indented side.
Planting Depth and Spacing
Getting the depth right is a "quiet winner" in gardening. You do not need to bury begonia tubers deeply.
- For Containers: Fill a pot with moist potting mix. Place the tuber on the surface with the indented side facing up. Press it gently into the soil so it is mostly covered, but the very top is still visible or just barely under a thin layer of soil (about half an inch deep).
- For Garden Beds: Space tubers about 8 to 12 inches apart. This gives the plants plenty of room for air to circulate around the leaves, which helps keep them healthy.
- Watering: After planting, water lightly to settle the soil.
What to Do Next
- Check that the indented side of the tuber faces upward.
- Keep the soil lightly moist but never soggy during the first few weeks.
- Place the pots in a warm spot with indirect light.
- Wait for the first sprouts to appear before moving them to their final summer home.
Watering Correctly, Not Constantly
One of the most common mistakes in gardening is watering too often. Begonias prefer a "deep drink, then dry a bit" approach. Because their stems are thick and hold water, they are actually quite forgiving if you miss a day of watering.
The Finger Test
The easiest way to tell if your begonia needs water is to stick your finger about an inch into the soil. If the soil feels dry, it is time to water. If it feels cool and damp, wait another day or two.
When you do water, try to pour the water directly onto the soil rather than over the leaves. Wet leaves, especially in humid weather, can sometimes lead to mildew or spotting. Watering in the morning is also helpful because it allows any accidental splashes on the foliage to dry out in the sun during the day.
Adjusting for Containers
Plants in containers and hanging baskets dry out much faster than those in the ground. On a hot summer day, a hanging basket may need water every day. If your container feels very light when you lift it, the soil is likely dry all the way through.
Feeding for Better Blooms
While begonias are not "heavy feeders," they do appreciate a little extra nutrition to keep those big blooms coming all summer long. A balanced, water-soluble fertilizer is the easiest way to provide this.
Most gardeners find success using a fertilizer labeled for flowering plants. You can apply this at half-strength every two weeks throughout the growing season. This consistent supply of nutrients ensures the plant has what it needs to produce new buds. If you notice the leaves are very dark green and lush but there are no flowers, you might be using too much nitrogen. Switching to a "bloom booster" formula can help encourage more flowers.
Simple Maintenance for a Clean Look
Begonias are relatively low-maintenance, but a few minutes of "deadheading" each week will keep them looking their best. Deadheading is simply the process of removing flowers that have finished blooming and are starting to fade.
When a flower begins to wilt, follow the stem back to where it meets the main plant and snap or snip it off. This prevents the plant from spending energy on producing seeds and encourages it to put that energy into making new flowers instead.
Similarly, if you see any yellowing or damaged leaves, go ahead and remove them. Keeping the plant clean not only makes it look better but also improves airflow, which keeps the plant healthy.
Key Takeaway Regular deadheading and removing old leaves keeps begonias looking fresh and encourages a constant cycle of new blooms.
Handling the Change of Seasons
Begonias are tropical plants, which means they do not like the cold. In most parts of the United States, they are grown as annuals, meaning they complete their life cycle in one season. However, because tuberous begonias grow from a sturdy base, you can actually save them for next year. Longfield Gardens also shares more growing advice in our Learn library.
Overwintering Tubers
When the leaves begin to turn yellow in late autumn or after the first light frost, it is time to bring the tubers inside.
- Lift the Tubers: Gently dig up the tubers or remove them from their pots.
- Dry Them Out: Cut off the remaining stems and leaves. Place the tubers in a cool, dry, shady spot for a few days until the outer skin feels dry.
- Storage: Place the tubers in a paper bag or a box filled with dry peat moss or sawdust.
- Temperature: Store them in a cool, dark place where the temperature stays around 40°F to 50°F, like a basement or a cool closet.
In the spring, about eight weeks before the last frost, you can take them out of storage and start the planting process all over again. This is a very cost-effective way to enjoy the same beautiful flowers year after year.
Growing Begonias in Different Climates
While we aim to make gardening simple, it is important to acknowledge that weather and local conditions play a role. A begonia in a humid climate like Florida will have different needs than one in a dry climate like Arizona.
- Hot, Dry Climates: In areas with very low humidity, begonias may need a bit more shade and more frequent watering. Using a layer of mulch around the base of the plants can help keep the soil cool and retain moisture.
- Cool, Rainy Climates: If your summers are cool and wet, you may need to be extra careful about drainage. Ensure your pots have plenty of holes and avoid overwatering, as the soil will stay damp longer on its own.
No matter where you live, starting with a healthy plant or tuber is the best way to ensure success. We work with trusted growers to ensure the tubers you receive are of the highest quality and ready to perform in your garden. You can also review our Shipping Information before you order.
Decorating with Begonias
One of the reasons we love begonias so much is their versatility. They aren't just for garden beds; they are design tools for your entire outdoor living space.
The Power of Containers
Because begonias are so easy to grow in pots, you can move them around to suit your needs. If you are hosting a backyard dinner party, you can move your best-looking begonia pots to the patio for an instant centerpiece. They also work well in mixed containers. Try pairing the bold foliage of a Rex begonia with a delicate, trailing plant like lobelia or bacopa for a professional-looking arrangement. For hanging baskets, Begonia Hanging Golden Balcony is a striking choice.
Creating a Unified Look
Repeating the same variety of begonia across your landscape can create a sense of harmony. For example, using the same color of "Nonstop" begonias in both your window boxes and your front border ties the different parts of your yard together. If you want a more upright look, Roseform Pink gives large, classic blooms.
Troubleshooting Common Issues
Even though begonias are easy to grow, you might occasionally run into a small hurdle. Leading with a simple fix is usually the best way to get back on track.
- If the leaves are turning yellow: This is often a sign of too much water. Try letting the soil dry out a bit more between waterings.
- If the plant looks "leggy" or stretched out: It might be looking for more light. Move it to a slightly brighter spot.
- If the leaves look scorched or have brown edges: The plant is likely getting too much direct afternoon sun. Provide a bit more shade or move the container to a protected area.
Most of the time, simply adjusting the light or water will fix the problem. Gardening is about observing your plants and making small changes to help them thrive. If you want to know how Longfield Gardens evaluates plants for performance, see About Us.

FAQ
Can I grow begonias in full sun?
While most begonias prefer shade or filtered light, certain varieties like wax begonias and the Solenia series are bred to handle more sun. If you plant them in a sunny spot, ensure they receive extra water to prevent the soil from drying out too quickly and causing the leaves to scorch.
Why are the flower buds falling off my begonia?
Bud drop is usually caused by a sudden change in the environment, such as a extreme heat wave or the soil becoming either too bone-dry or completely waterlogged. To help your plant, keep the moisture levels consistent and move containers to a cooler, shadier spot during unusually hot weather.
Do I need to dig up my begonias in the winter?
In USDA zones 9-11, begonias can often stay in the ground year-round. However, in colder climates (zones 8 and lower), tuberous begonias will not survive the winter frost. You can either treat them as annuals and plant new ones each spring or dig up the tubers in the fall and store them in a cool, dry place indoors. For help choosing the right area to plant, the Hardiness Zone Map is a useful reference.
Are begonias safe for pets?
Most begonias are considered toxic if ingested by cats or dogs, with the tubers being the most concentrated source of the irritating compounds. It is always a good idea to keep your plants out of reach of curious pets and consult a veterinarian if you suspect your pet has eaten any part of the plant.
