Introduction

Finding a plant that offers non-stop color from early summer until the first frost is a highlight for any gardener. Begonias are one of those rare garden treasures that actually prefer the shaded corners of your yard where other flowers might struggle, and the Upright Double Begonias collection is a great place to start if you want dramatic tuberous blooms. Whether you want to fill a hanging basket with trailing blooms or add a splash of color to a woodland border, these plants are remarkably reliable.

At Longfield Gardens, we believe that everyone can grow a beautiful garden regardless of their experience level. Begonias are a perfect choice for beginners because they are forgiving, versatile, and come in a stunning array of shapes and sizes. If you are just learning the basics, our Garden Basic Essentials guide is designed for home gardeners who want to understand which varieties fit their space and how to keep them thriving all season long.

While some plants require constant attention, begonias are famously low-maintenance. Once you get a few simple basics right—like light and water—they will reward you with lush foliage and vibrant flowers for months. Begonias are exceptionally easy to grow if you choose the right variety for your location and follow a few straightforward care steps.

Why Begonias Are a Beginner's Best Friend

Many people ask if begonias are easy to grow because they look so exotic and lush. Their delicate-looking petals and intricate leaf patterns give the impression of a high-maintenance plant. However, the opposite is true. Begonias are rugged tropical plants that have been adapted for home gardens over decades.

The biggest advantage of begonias is their ability to thrive in low-light conditions. Most colorful annuals, like petunias or geraniums, need six to eight hours of direct sun to bloom well. Begonias, on the other hand, are the stars of the shade. If you are planning a planting site, our How Sunlight Affects Plants guide can help you match light levels to the right plant.

Another reason they are so easy is their "self-cleaning" nature. Many flowering plants require "deadheading," which is the process of pinching off spent blooms to encourage new ones. Most modern begonia varieties drop their old flowers naturally. This means you can enjoy a tidy-looking garden without spending every weekend with a pair of snips.

Key Takeaway: Begonias are ideal for beginners because they bloom in the shade, require very little pruning, and offer more color for less effort than almost any other summer flower.

Choosing the Right Begonia for Your Space

The key to easy gardening is matching the plant to its environment. There are thousands of begonia species, but for the home gardener, they generally fall into four main categories. Each has slightly different needs and growth habits.

Tuberous Begonias

These are the showstoppers of the begonia world. They grow from a potato-like bulb called a tuber and produce large, rose-like flowers. Tuberous begonias are famous for their intense colors, including neon oranges, deep reds, and soft bicolors. For a focused selection of tuberous forms, browse the Non-Stop Begonias collection.

We often recommend tuberous begonias for gardeners who want high-impact containers. They are divided into two main growth habits:

• Upright Tuberous Begonias: These grow in a mounded shape and are perfect for garden beds or large pots.
• Trailing Tuberous Begonias: Also known as pendula types, these have stems that cascade gracefully over the sides of hanging baskets and window boxes.

Wax Begonias

If you are looking for a plant that is nearly indestructible, wax begonias are the answer. These have shiny, succulent-looking leaves and small, cherry-like blossoms. They are incredibly versatile and can handle more sun than most other types.

Wax begonias are often used as "bedding plants." This means they are planted in large groups to create a carpet of color along a walkway or border. You can choose varieties with green leaves or bronze leaves. The bronze-leafed types are particularly hardy and can withstand higher heat and brighter light.

Dragon Wing and Interspecific Begonias

These are often called "begonias on steroids." They grow much larger and faster than standard wax begonias. A single Dragon Wing begonia can easily fill a large pot by mid-summer. They have elongated, wing-shaped leaves and large clusters of drooping flowers.

These are arguably the easiest begonias to grow because they are vigorous and highly resistant to pests and diseases. They perform well in both sun and shade, making them a "fail-safe" option if you aren't quite sure how much light your spot gets.

Rex Begonias

Rex begonias are grown primarily for their foliage rather than their flowers. Their leaves are works of art, featuring swirls of silver, purple, pink, and burgundy. While they are often grown as houseplants, they are excellent additions to outdoor shade containers in the summer. They add texture and color that lasts all season, regardless of whether the plant is in bloom.

The Simple Rules of Planting

Success with begonias starts with how you put them in the ground or the pot. Because they are tropical plants, they are sensitive to cold. Timing and depth are the most important factors here.

Wait for Warm Weather

The most common mistake gardeners make is planting too early. Begonias love warmth and hate frost. In most regions, you should wait until the soil has warmed up and the nights are consistently above 60°F. If you want a planting timetable that matches your region, Longfield Gardens' Hardiness Zone Map is a helpful place to check.

Planting Depth and Direction

If you are starting with tubers, look for the "belly button." One side of the tuber is usually indented or hollow, while the other is rounded.

• The Indented Side: This should face up. This is where the stems and leaves will emerge.
• The Rounded Side: This should face down into the soil.

Plant the tubers about 1/2 inch to 1 inch deep. They don't need to be buried deep in the earth. In fact, keeping them near the surface helps the sun warm the tuber and encourages faster sprouting. For wax begonias or started plants in nursery pots, plant them at the same depth they were in their original container.

Spacing for Airflow

It is tempting to pack plants close together for an instant full look. However, begonias appreciate a little elbow room. Good airflow helps prevent powdery mildew, a common fungus that can make leaves look dusty.

• Tuberous Begonias: Space them about 8 to 12 inches apart.
• Wax Begonias: Space them 6 to 8 inches apart.
• Dragon Wing Types: Give them 12 to 15 inches of space to expand.

What to do next:

• Check your local frost dates before ordering.
• Prepare your pots with fresh, well-draining potting mix.
• Identify the "up" side of your tubers before planting.
• Ensure your chosen containers have drainage holes.

Mastering Light and Water

Once your begonias are planted, their ongoing care is very simple. You don't need a green thumb to keep them happy; you just need to observe the plant and the soil.

Finding the Sweet Spot for Light

While begonias are shade plants, "shade" doesn't mean total darkness. They still need light to produce energy and flowers.

• Filtered Light: The ideal setting is "dappled" or "filtered" sunlight—think of the light under a tall tree.
• Morning Sun: Eastern exposure is excellent. The gentle morning sun provides energy, while the shade in the hot afternoon protects the leaves from scorching.
• Avoid Deep Shade: If your begonias are growing very tall and "leggy" with few flowers, they likely need a bit more light.

The Right Way to Water

The quickest way to stress a begonia is by keeping the soil constantly soggy. "Drainage" is the most important word in begonia care. Drainage simply means how fast water leaves the soil. Begonias have fleshy, succulent stems that store water, which makes them somewhat drought-tolerant, but it also makes them prone to rot if they sit in a puddle.

Use the "Finger Test." Stick your finger about an inch into the soil. If it feels moist, wait another day to water. If it feels dry, give it a good soak. When watering, try to aim for the base of the plant rather than splashing the leaves. Wet leaves in a shaded area can sometimes lead to spotting or fungus.

Feeding Your Plants

Because begonias bloom so prolifically, they appreciate a little extra food. A balanced, water-soluble fertilizer applied every two to three weeks is usually plenty. If you are growing them in containers, the frequent watering will wash nutrients out of the soil, so regular feeding is more important for pots than for garden beds.

Growing Begonias in Containers

Containers are where begonias truly shine. Because you have total control over the soil and the location, growing in pots is often easier than growing in the ground.

Choosing the Right Pot

Begonias don't have very deep root systems. This means they don't necessarily need a massive, deep pot to thrive. A wider, shallower container often works better because it allows the soil to dry out more evenly. Most importantly, ensure the pot has at least one large drainage hole at the bottom. If you find a beautiful decorative pot without a hole, use it as a "cachepot"—keep the begonia in a plain plastic nursery liner with holes and set that inside the decorative one.

Using Quality Soil

Always use a high-quality potting mix designed for containers. Never use "garden soil" or "topsoil" from the hardware store in a pot. Native soil is too heavy and will pack down, crushing the begonia's delicate roots and preventing air from reaching them. A good potting mix will be light and fluffy, often containing peat moss or perlite to help with drainage.

Maintenance Tips for Pots

Potted begonias can sometimes become top-heavy as they grow. If your upright tuberous begonias start to lean, you can use a small bamboo stake to give them support. For trailing begonias in hanging baskets, rotate the basket every week. This ensures all sides of the plant get equal light, preventing it from becoming "bald" on the side facing the wall.

Key Takeaway: For the easiest experience, plant begonias in containers with fresh potting mix. This gives you the best control over moisture and allows you to move the plants if you find they are getting too much or too little sun.

Handling Heat and Humidity

Begonias are native to tropical and subtropical regions, so they generally enjoy humidity. However, extreme heat can be a challenge for some types.

Tuberous Begonias vs. Heat

Tuberous begonias (like the Nonstop or Picotee varieties) prefer moderate temperatures. If you live in a region with very hot, humid summers (like the US South), these plants may "sulk" or stop blooming during the hottest weeks of July and August. To help them through, move your pots to the coolest, shadiest spot you have during heat waves.

Heat-Tolerant Options

If your garden is naturally quite warm, wax begonias and interspecific types (like the "Big" or "Dragon Wing" series) are much better choices. These varieties have been bred specifically to handle the heat and will continue to pump out flowers even when the thermometer climbs.

Overwintering: Saving Your Begonias for Next Year

One of the best things about begonias is that you don't have to buy new ones every year if you don't want to. While many people treat them as annuals, you can easily save the tubers for the following spring. This is a great way to save money and watch your plants get larger and more impressive each season.

How to Save Tuberous Begonias

1. Watch the Weather: In the fall, after the first light frost kills the foliage, or when the leaves start to turn yellow naturally, stop watering the plant.
2. Lift the Tubers: Carefully dig the tubers out of the ground or remove them from the pot.
3. Clean and Dry: Shake off the excess soil and cut the stems back to about an inch. Let the tubers sit in a dry, shady spot for a few days to "cure."
4. Store for Winter: Place the dry tubers in a paper bag or a box filled with dry peat moss or sawdust. Keep them in a cool, dark, and dry place (like a basement or crawl space) where the temperature stays between 40°F and 50°F.
5. Replant in Spring: When the weather warms up again, bring them out, give them a little water to wake them up, and start the cycle over.

Saving Other Types

Wax begonias and Rex begonias don't have large tubers, so they can't be stored dry. If you want to keep these, you'll need to bring them inside as houseplants before the first frost. Place them in a bright window and reduce your watering. They may not look their best during the dark winter months, but they will bounce back once they go back outside in the spring.

Troubleshooting Made Easy

Even though begonias are easy to grow, you might run into a few common hitches. Most of these are solved by adjusting your care routine.

Why Won't My Begonias Bloom?

If you have plenty of green leaves but no flowers, the most likely culprit is too much shade. While they love shade, they still need indirect light to produce the energy for blooming. Try moving your container to a slightly brighter spot. Another possibility is too much nitrogen fertilizer, which encourages leaves over flowers. Switch to a "bloom booster" fertilizer with a higher middle number (phosphorus).

Why Are the Leaves Turning Yellow?

Yellow leaves are almost always a sign of "wet feet." If the soil stays soggy for too long, the roots can't breathe. This causes the leaves to yellow and eventually drop. Check the drainage of your pot and cut back on watering. Only water when the top inch of soil feels dry to the touch.

What Is the White Dust on the Leaves?

This is likely powdery mildew. It usually happens when the air is stagnant and humid. You can help prevent this by giving your plants more space for airflow and avoiding watering from above. If it appears, you can find simple organic sprays at your local garden center to treat it.

What to do next:

• Monitor your plants weekly for any changes in leaf color.
• Adjust your watering schedule based on the weather—hotter days need more frequent checks.
• If you see pests like aphids or snails, a gentle spray of water or neem oil usually solves the problem.

Planting for the Future

Gardening should be a source of relaxation, not a list of chores. Begonias fit this philosophy perfectly. They ask for very little—just a shady spot and a bit of water—and in return, they provide a spectacular show of color that lasts longer than almost any other garden plant.

FAQ

Can begonias grow in full sun?

Most begonias prefer shade or partial shade, but some varieties are more sun-tolerant than others. Wax begonias with bronze-colored leaves can often handle full sun if they receive plenty of water. However, tuberous begonias will usually scorch in direct afternoon sun, so it is best to keep them in filtered light or morning sun. For more planting guidance, see Shipping Information so you can time delivery with your local weather.

Do begonias come back every year?

In warm climates (USDA zones 9–11), begonias can live outdoors year-round. In colder regions, they are killed by frost and are usually grown as annuals. However, you can save tuberous begonias by digging up the tubers in the fall and storing them in a cool, dry place to replant the following spring.

How often should I water my begonias?

There is no set schedule because water needs depend on your local weather and soil. The best method is to check the soil with your finger. If the top inch of soil is dry, it is time to water. Begonias prefer to be slightly dry rather than sitting in soggy soil, so always err on the side of underwatering rather than overwatering. If you need help choosing plants for your climate, revisit the Hardiness Zone Map.

Are begonias safe for pets?

Begonias contain calcium oxalates, which can be toxic to cats and dogs if ingested. The most concentrated amount of these crystals is in the tubers or roots. If you have curious pets that like to dig or chew on plants, it is best to keep your begonias in hanging baskets or elevated pots where they are out of reach.
