Introduction

There is a special kind of excitement that comes with finding the perfect plant for a shady corner of the garden. While many flowering plants crave intense, all-day sun, a begonia plant thrives in those softer, dappled spaces where other flowers might struggle. These versatile plants offer a spectacular range of colors and leaf patterns, making them a favorite for both new gardeners and seasoned experts. At Longfield Gardens, we love how begonias can instantly transform a porch, patio, or garden bed into a lush, tropical-feeling retreat.

Whether you want to fill a hanging basket with cascading blooms or add unique textures to your indoor plant collection, begonias are a rewarding choice. This guide will help you understand the different types of begonias available and provide simple, practical steps for keeping them healthy. We will cover everything from choosing the right location to ensuring your plants thrive throughout the growing season. By focusing on a few basic needs, you can enjoy the vibrant beauty of these plants in your own home and landscape.

Growing begonias is an achievable and enjoyable way to bring more color into your life.

Understanding the Main Types of Begonias

Before you bring home a begonia plant, it is helpful to know that this is a very large family of plants. With over 2,000 species and many more hybrids, begonias come in many shapes and sizes. However, most gardeners focus on four main groups. Knowing which type you have makes it much easier to provide the right care.

Wax Begonias

Wax begonias are some of the most common bedding plants in the United States. You will recognize them by their fleshy, succulent-like stems and shiny, waxy leaves. The leaves can be bright green, bronze, or even a deep mahogany color. These plants are generally compact, growing between 6 and 12 inches tall.

They produce clusters of small flowers in shades of white, pink, and red. Wax begonias are incredibly reliable and are often used to create colorful borders or "carpets" of flowers in garden beds. They are also quite sturdy and can handle more sun than some of their cousins, especially if they have darker foliage.

Tuberous Begonias

If you are looking for large, show-stopping flowers, Begonia Upright Double Roseform Pink fits the bill. These plants grow from a thickened underground stem called a tuber. The blooms can be truly spectacular, sometimes reaching several inches across and looking much like roses or camellias.

Tuberous begonias come in two main growth habits: upright and trailing. Upright varieties are perfect for garden beds and pots, while trailing (or "pendula") types look beautiful spilling over the edges of hanging baskets. These plants prefer cooler temperatures and filtered light, making them the stars of the summer shade garden.

Cane Begonias

Cane begonias get their name from their long, upright stems that look a bit like bamboo. The most famous members of this group are the "Angel Wing" begonias. You can identify them by their long, asymmetric leaves that are shaped like a bird's wing.

Many cane begonias have stunning foliage, often featuring silver spots or metallic splashes. They also produce clusters of drooping flowers that can last for a long time. These begonias are excellent as large houseplants but can also spend the summer outdoors in a protected, shady spot.

Rhizomatous and Rex Begonias

Rhizomatous begonias are primarily grown for their incredible leaves. Instead of growing from a single central stem, they spread via thick horizontal stems called rhizomes that sit right at the soil surface.

Rex begonias are a specific type of rhizomatous begonia known for having some of the most colorful foliage in the plant world. Their leaves can feature swirls of purple, silver, pink, and burgundy. While they do produce flowers, the blooms are usually small and take a backseat to the dramatic foliage. These are very popular as indoor decorative plants.

Key Takeaway: Identifying your begonia type is the first step to success. Wax begonias are great for bedding, tuberous begonias offer the biggest flowers, cane types provide height and interesting leaves, and Rex begonias are the champions of colorful foliage.

Finding the Perfect Spot for Your Begonia Plant

One of the most important rules for a happy begonia plant is matching the plant to the right location. Most begonias evolved as "understory" plants, meaning they grew on the forest floor beneath the canopy of taller trees. This gives us a big clue about what they need to thrive.

Light Requirements

Most begonias prefer "dappled" or "filtered" light. This is the kind of light you see under a tree where the sun peeks through the leaves. If you place a begonia in direct, harsh afternoon sun, the leaves may scorch or turn brown at the edges.

• Shade: This means a spot that gets very little direct sun but is still bright enough to read a book. Most begonias love this.
• Partial Shade: This is often the "sweet spot." A location with gentle morning sun and protection from the hot afternoon sun is ideal.
• Sun-Tolerance: Some wax begonias and newer hybrids are bred to handle more sun. If you have a sunny spot, look for varieties with bronze or dark leaves, as they naturally handle light better than green-leaved types. For more ideas on matching plants to a shady space, see our Summer Bulbs for Shady Gardens.

Soil and Drainage

In the gardening world, "drainage" simply means how fast water leaves the soil. Begonias have very tender, succulent stems that can rot if they sit in soggy soil for too long. To keep them healthy, you need soil that holds a little moisture but lets the excess run away freely.

If you are planting in the ground, adding some organic matter like compost can help improve the soil texture. For containers, always use a high-quality potting mix rather than garden soil. Make sure your pots have holes in the bottom so water can escape.

Temperature and Airflow

Begonias are tropical plants at heart. They love warmth but don't like to be "stifled." Good airflow is important because it helps prevent fungal issues like powdery mildew (which looks like a dusting of white flour on the leaves).

Avoid crowding your plants too closely together. A little bit of space between each plant allows the air to circulate, which keeps the foliage dry and healthy. Also, wait until the weather is consistently warm before moving your plants outside. If the nighttime temperatures are still dipping below 50°F, it is best to keep them protected indoors a little longer.

How to Plant Begonias Step-by-Step

Planting is an exciting time because it sets the foundation for the entire season. Whether you are starting with tubers or nursery transplants, the process is straightforward.

Planting Begonia Tubers

Tuberous begonias are often started indoors in late winter or early spring. This gives them a "head start" so they are ready to bloom as soon as the weather warms up.

1. Check the Tuber: Look at the tuber and find the side with a slight hollow or indentation. This is the top, where the sprouts will grow. The rounded, smooth side is the bottom.
2. Start Indoors: Fill a shallow tray with moist potting mix. Place the tubers on the surface about an inch apart with the hollow side facing up.
3. Cover Lightly: Cover them with just a half-inch of soil. Keep the tray in a warm spot (around 70°F) with bright, indirect light.
4. Wait for Sprouts: Keep the soil moist but never wet. Once the sprouts are about an inch tall, you can move them into their individual pots.
5. Move Outside: Wait until all danger of frost has passed before moving these plants to their permanent home in the garden or on the patio.

Planting Nursery Transplants

If you bought a begonia plant that is already growing in a small plastic pot, the transition to your garden is even easier.

1. Prepare the Hole: Dig a hole that is just a little bit wider than the pot the plant is currently in.
2. Check the Depth: When you put the plant in the hole, the top of the root ball should be level with the surrounding soil. Planting it too deep can lead to stem rot.
3. Gently Loosen Roots: If the plant's roots are circling the inside of the pot, gently tease them outward with your fingers before planting.
4. Fill and Firm: Fill in the space around the roots with soil and press down gently with your hands to remove any large air pockets.
5. Water Immediately: Give the plant a good drink of water to help the soil settle around the roots.

Spacing Your Plants

It can be tempting to plant everything close together for an instant full look, but remember that begonias will grow!

• Wax begonias: Space them about 6 to 8 inches apart.
• Tuberous begonias: Space them about 10 to 12 inches apart.
• Large cane begonias: These might need 15 to 18 inches of space.

What to Do Next:

• Choose your planting site based on the light needs of your specific begonia type.
• Check your pots for drainage holes before you start.
• If planting tubers, ensure the "hollow" side is facing up.
• Give each plant enough room to breathe to prevent leaf issues.

Essential Care for a Thriving Begonia Plant

Once your begonia plant is in its new home, it only needs a few things to keep producing beautiful flowers and foliage. The goal is to provide a consistent environment that mimics the tropical forest floor.

Watering Correctly

Watering is the area where most gardeners make mistakes, but it doesn't have to be complicated. The "finger test" is your best tool. Stick your finger into the soil up to the first knuckle. If the soil feels dry, it is time to water. If it feels damp or cold, wait a day or two and check again.

Begonias prefer "deep" watering. This means applying enough water so that it reaches the roots, then letting the top inch of soil dry out slightly before watering again.

• Avoid the leaves: Try to water the soil at the base of the plant. Getting water on the leaves can lead to spots or fungal growth.
• Morning is best: Watering in the morning allows any moisture on the stems to dry out during the day.
• Check containers often: Plants in pots and hanging baskets dry out much faster than those in the ground. During the hottest part of the summer, you may need to check them every day.

Feeding Your Plants

Think of fertilizer as a vitamin boost for your plants. Begonias are "heavy feeders," which means they use up a lot of energy to keep those big leaves and bright flowers growing.

We recommend using a balanced, water-soluble fertilizer. "Balanced" means the three numbers on the package (Nitrogen, Phosphorus, and Potassium) are roughly equal, such as 10-10-10 or 20-20-20. Follow the instructions on the label, but generally, feeding your plants every two to four weeks during the growing season is plenty.

If you are growing begonias mainly for their leaves (like Rex begonias), a fertilizer slightly higher in Nitrogen can help promote lush, green growth.

Grooming and Deadheading

"Deadheading" is just a gardening term for removing old, faded flowers. On many begonias, the flowers are "self-cleaning," meaning they fall off on their own when they are finished. However, if you see spent blooms hanging onto the plant, pinching them off with your fingers keeps the plant looking tidy and encourages it to produce even more flowers.

If your begonia plant starts to look "leggy" (with long, thin stems and few leaves at the bottom), don't be afraid to give it a little trim. Pinching back the tips of the stems will encourage the plant to grow more side branches, resulting in a fuller, bushier shape.

Growing Begonias as Houseplants

Many begonias make wonderful houseplants. In fact, some varieties like the Rex and Angel Wing types are often grown more for their indoor beauty than for the garden.

Indoor Light and Temperature

Inside your home, the best place for a begonia plant is near a bright window. An east-facing or west-facing window is usually perfect. They will appreciate the bright light but stay protected from the most intense heat. If the leaves start to look pale or the stems are stretching toward the glass, the plant likely needs a bit more light.

Begonias are very comfortable at the same temperatures humans enjoy—roughly 65°F to 75°F. Keep them away from cold drafts or heating vents, which can dry out the air too much.

Managing Humidity

One of the biggest challenges for indoor begonias is dry air, especially in the winter when the heat is on. These plants love humidity. You can help them out by:

• Grouping plants together: Plants naturally release moisture through their leaves, and grouping them creates a little pocket of humid air.
• Using a pebble tray: Fill a shallow tray with small stones and add water until it is just below the top of the stones. Sit your begonia pot on top of the stones. As the water evaporates, it creates a humid "microclimate" around the plant.
• Misting: Some people like to mist their plants with a spray bottle, but be careful not to overdo it, as standing water on leaves can cause problems.

Overwintering Your Begonias

Since begonias are not cold-hardy, they will not survive a freeze. However, you don't have to lose your favorite plants when winter arrives. You can choose to bring them inside as houseplants or store their tubers.

Bringing Pots Inside

Wax begonias and cane begonias can be moved indoors for the winter. Before the first frost, check the plants for any unwanted guests like small insects. Give the leaves a gentle rinse and move the pots into a bright room. The plants may drop a few leaves as they adjust to the lower light levels inside, but they will soon settle in. Reduce your watering and stop fertilizing during the winter months when the plant is growing more slowly.

Storing Begonia Tubers

Tuberous begonias have a natural dormant period. In the fall, when the leaves start to turn yellow and the plant looks like it is finished for the season, it is time to prepare the tubers for storage.

1. Stop Watering: Let the soil dry out.
2. Dig Them Up: After the first light frost has blackened the foliage, carefully dig the tubers out of the ground or remove them from their pots.
3. Clean and Dry: Trim off the stems and gently brush away the excess soil. Let the tubers sit in a dry, sunny spot indoors for about a week to "cure."
4. Store: Place the dry tubers in a box filled with peat moss, sawdust, or shredded paper. Keep the box in a cool, dark, dry place where it won't freeze (like a basement or a closet).
5. Check Periodically: Once or twice during the winter, check on your tubers to make sure they aren't shriveling up or rotting. If they look very dry, a tiny mist of water can help.

Designing Your Garden with Begonias

Begonias are incredibly versatile tools for garden design. Because they come in so many colors and sizes, they can fill many different roles in your landscape.

Using Begonias in Containers

Containers are perhaps the most popular way to grow begonias. Because you can control the soil and move the pots around, it is easy to give them the perfect conditions. For more container-growing ideas, see our container plants.

• Hanging Baskets: Trailing tuberous begonias (pendula types) are magnificent in baskets. They create a "waterfall" of color that looks beautiful on a front porch.
• Window Boxes: Wax begonias are a classic choice for window boxes. Their compact size and constant blooms provide a neat, tidy look all summer.
• Mixed Planters: Use begonias as a "filler" or "spiller" in larger pots. Pair them with other shade-loving plants like coleus, ferns, or caladiums for a textured, layered look.

Begonias in the Landscape

In the ground, begonias can be used to brighten up areas that might otherwise feel dark.

• Edging: Use a row of wax begonias to line a garden path. Their consistent height creates a clean border.
• Mass Plantings: Planting a large group of the same color begonia creates a high-impact "sweep" of color that draws the eye.
• Under Trees: Begonias are one of the few flowers that can compete with tree roots and still look great in the shade. Just be sure to give them a little extra water, as the tree will be thirsty too.

Choosing Varieties We Love

When you browse the selection at Longfield Gardens, you will see a wide variety of tuberous begonias, including Non Stop Begonias, that we have carefully selected for their performance and beauty. Here are a few of our favorites to consider:

• Roseform Begonias: These produce large, double blooms that look exactly like garden roses. They come in vibrant reds, soft pinks, and cheerful yellows.
• Begonia Upright Double Picotee White: These are truly unique, featuring petals that are one color on the inside with a contrasting "edge" of a different color. They add a sophisticated touch to any container.
• Fimbriata Begonias: If you like texture, these are for you. The edges of the petals are ruffled or "fringed," giving the flowers a soft, carnation-like appearance.
• Pendula (Trailing) Begonias: These are the best choice for hanging baskets. They branch freely and produce hundreds of smaller, drooping flowers that create a lush canopy of color.

Key Takeaway: Whether you want the rose-like elegance of a tuberous begonia or the reliable color of a wax begonia, there is a variety to fit every garden style. Focus on the colors and textures that make you happy!

Simple Troubleshooting for Common Issues

Even the healthiest begonia plant can run into a few hiccups. Most of the time, the solution is simple and involves a small adjustment to your care routine.

• Yellowing Leaves: This is often a sign of too much water. Remember the "finger test"—only water when the top inch of soil feels dry. Make sure your pot isn't sitting in a tray of standing water.
• Brown Edges on Leaves: This usually means the plant is getting too much direct sun or the air is too dry. Try moving the plant to a slightly shadier spot or increasing the humidity if it is indoors.
• Powdery Mildew: If you see white, dusty spots on the leaves, the plant likely needs better airflow. Space your plants further apart and try to avoid getting the leaves wet when you water.
• Dropping Flowers: If a tuberous begonia drops its big buds before they open, it might be due to extreme heat. Move the pot to the coolest, shadiest spot you have until the heatwave passes.

Remember, gardening is a learning process. If a plant isn't doing well, try changing one thing at a time—like the amount of light or the frequency of watering—and see how the plant responds.

FAQ

Do begonias need sun or shade?

Most begonias prefer partial shade or filtered light, such as the dappled sunlight under a tree. While wax begonias with bronze foliage can handle more sun, most varieties will experience leaf scorch if left in the intense afternoon sun.

How often should I water my begonia plant?

There is no set schedule, but the best method is to check the soil with your finger. Water the plant when the top inch of soil feels dry to the touch, and always avoid getting water directly on the leaves to prevent disease.

Are begonias perennials or annuals?

In most parts of the United States, begonias are treated as annuals because they cannot survive freezing temperatures. However, they are technically tropical perennials and can be brought indoors for the winter or stored as tubers to grow again the following year. If you're not sure about your area, use the Hardiness Zone Map to confirm your zone.

Can I grow begonias as houseplants?

Yes, many begonias make excellent houseplants, especially Rex and Angel Wing varieties. They thrive in bright, indirect light and appreciate a bit of extra humidity, which can be provided by grouping plants together or using a pebble tray.
