We will cover everything from starting tubers indoors to maintaining healthy foliage all season long. With a few simple steps, you can transform your porch or garden beds into a colorful retreat. Growing these beautiful plants is an achievable and rewarding way to enhance your outdoor space. (longfield-gardens.com)
Understanding the Different Types of Begonias
Before you get started, it is helpful to know that not all begonias are the same. For a broader look at different types of begonias, this plant family is large and diverse, offering different growth habits and features. Identifying which type you have will help you provide the best care. (longfield-gardens.com)
Tuberous Begonias
Tuberous begonias are famous for their large, rose-like flowers, and upright double begonias are often used in containers or hanging baskets because many varieties have a lovely trailing habit. They grow from a thick, potato-like underground stem called a tuber. If you want big, bold blooms in shades of red, orange, yellow, or pink, this is the type for you. (longfield-gardens.com)
Wax Begonias
Wax begonias are the workhorses of the shade garden. They have small, succulent leaves that look like they have been polished with wax. These plants are typically used for bedding because they grow in neat, mounded clumps. They are very reliable and can handle a bit more sun than other varieties. (longfield-gardens.com)
Rex Begonias
If you love interesting foliage, rex begonias are a perfect choice. While they do produce flowers, they are primarily grown for their stunning leaves. You can find Rex varieties with swirls of silver, purple, burgundy, and green. They make excellent houseplants but also thrive in outdoor containers during the warm months. (longfield-gardens.com)
Cane-Like and Angel Wing Begonias
These begonias have upright, woody stems that resemble bamboo canes. Their leaves are often shaped like wings, which is how they earned their common name. Angel Wing Begonias produce drooping clusters of flowers and can grow quite tall if given the right support. (longfield-gardens.com)
Choosing the Best Location
Getting the location right is one of the most important parts of learning how to grow begonia plant varieties successfully. When you match the plant’s needs to the right spot in your yard, the rest of the care becomes much easier.
Sun and Shade Requirements
Most begonias prefer a spot with partial shade or filtered light. Direct afternoon sun can be too intense and may scorch the leaves. However, they do need some light to produce plenty of flowers. A spot that gets gentle morning sun and afternoon shade is often perfect.
If you have a very dark corner, choose varieties with green leaves, as they tend to be more shade-tolerant. Varieties with darker or bronze foliage can usually handle more sunlight without stress. In cooler northern climates, begonias can often tolerate more sun than they can in the hot, humid South.
Soil and Drainage
Begonias have relatively delicate root systems that do not like to sit in water. To keep them happy, you need soil that drains quickly. Drainage refers to how fast water leaves the soil after a rain or watering session.
If your garden soil is heavy clay, it may hold too much moisture. You can improve drainage by adding organic matter like compost or finely ground bark. For container gardening, always use a high-quality, soil-less potting mix. These mixes are designed to stay light and airy, which prevents the roots from suffocation.
Wind Protection
Because many begonias have fleshy, succulent stems, they can be somewhat brittle. Strong winds can snap the stems or damage the large leaves. Whenever possible, plant your begonias in a protected area, such as near a fence, under a porch, or tucked among sturdier shrubs.
Key Takeaway: Success starts with the right environment. Aim for filtered light, well-draining soil, and a spot protected from harsh winds.
How to Plant Begonia Tubers
If you are starting with tubers, the process is a little different than planting a nursery-grown transplant. Many gardeners choose tubers because they are cost-effective and offer a wider variety of colors and flower shapes. (longfield-gardens.com)
When to Start Tubers
Begonias are tropical plants that love warmth. They should not go into the ground until the soil is warm and the danger of frost has passed. In many regions, this is around late May or early June.
To get a head start on the growing season, you can start your tubers indoors about 8 to 12 weeks before the last frost date. This gives the plants time to develop leaves and roots so they are ready to bloom as soon as they move outside.
Identifying the Top of the Tuber
When you look at a begonia tuber, you will notice that one side is slightly indented or bowl-shaped. This concave side is the top. The leaf sprouts will emerge from this indentation. The rounded side is the bottom, where the roots will grow.
Step-by-Step Planting Process
- Prepare the container: Fill a shallow tray or small pots with moist potting soil.
- Place the tubers: Set the tubers on the soil surface with the indented side facing up.
- Cover lightly: Press the tubers gently into the soil. You only need to cover them with about half an inch of soil. At our trial garden, we find that leaving the very top of the tuber slightly exposed can help prevent moisture from sitting in the "bowl" and causing rot.
- Water sparingly: Give them a light drink to settle the soil. Do not soak them.
- Provide warmth: Place the containers in a warm spot (around 65–70°F) with indirect light.
- Wait for growth: It can take several weeks for the first sprouts to appear. Be patient—this is an exciting time! (longfield-gardens.com)
Spacing Your Plants
Once it is time to move them into the garden or their final large pots, spacing is key. Proper spacing ensures that air can circulate around the plants, which helps prevent disease.
- Small varieties: Space about 6 to 8 inches apart.
- Large varieties: Space 10 to 12 inches apart.
Planting Nursery Transplants
If you prefer to start with established plants from a garden center, the process is quick and simple. This is often the best route for wax begonias used as bedding plants.
Transitioning to the Outdoors
If your plants have been in a greenhouse, they need a few days to adjust to the outdoor air. This is called "hardening off." Place them in a sheltered, shady spot for a few hours each day, gradually increasing their time outside.
The Planting Step
Dig a hole that is slightly wider than the root ball of your plant. Gently remove the begonia from its nursery pot. If the roots are circling the bottom, you can lightly tease them outward with your fingers. Set the plant in the hole so the top of the root ball is level with the surrounding soil. Fill in with dirt and press down lightly to remove air pockets.
Watering Correctly for Healthy Growth
Watering is the area where most new gardeners feel unsure. For begonias, the rule is "consistent moisture without sogginess."
Check the Soil First
Before you reach for the watering can, poke your finger into the soil. If the top inch feels dry, it is time to water. If it still feels damp, wait a day or two. Begonias store a fair amount of water in their thick stems, so they are slightly more tolerant of drying out than they are of being overwatered.
How to Water
When you water, aim the stream at the base of the plant. Avoid splashing the leaves as much as possible. Wet foliage can lead to fungal issues like powdery mildew. If you are growing begonias in containers, water until you see it running out of the drainage holes at the bottom. This ensures the entire root system gets a drink.
Adjusting for Weather
During the heat of mid-summer, your begonias will use water more quickly. You might need to check them daily, especially those in hanging baskets or small pots. In cooler, cloudy weather, they will stay moist much longer.
Key Takeaway: Always check the soil moisture with your finger before watering. Focus on the soil, not the leaves, to keep the plant healthy.
Feeding and Fertilizing
Begonias are "heavy feeders," which means they need plenty of nutrients to keep producing those beautiful flowers and leaves all summer long.
Starting at Planting
When you first put your plants in the ground or a pot, you can mix a slow-release fertilizer into the soil. This provides a steady, low-dose supply of food over several months. Follow the instructions on the packaging for the correct amount.
Supplemental Feeding
For the best results, we suggest using a balanced liquid fertilizer once a month during the growing season. A "balanced" fertilizer is one where the three numbers on the label (nitrogen, phosphorus, and potassium) are the same, such as 10-10-10. This support helps the plant maintain its vigor from July through September.
Maintenance and Pruning
Begonias are generally low-maintenance, but a little bit of grooming goes a long way in keeping them looking their best.
Deadheading
Many modern begonia varieties, like Non-Stop begonias, are "self-cleaning." This means the old flowers fall off on their own, and you don't have to pinch them off. However, if you have traditional tuberous begonias, removing the faded blooms (deadheading) can encourage the plant to put its energy into new flowers rather than seed production. (longfield-gardens.com)
Controlling Leggy Growth
If your begonias start to look long and "leggy" with more stem than leaves, you can give them a light trim. Pinching off the tips of the stems encourages the plant to branch out, resulting in a bushier, fuller appearance.
Keeping the Garden Clean
Occasionally, a leaf might turn yellow or brown. This is normal. Simply snip off any damaged or dying leaves to keep the plant looking tidy. Removing debris from the top of the soil also helps prevent pests and disease from taking hold.
Growing Begonias in Containers
Begonias are perhaps the ultimate container plant, and the Perfect Pairs collection makes it easy to build a polished display. Because they love the drainage and controlled environment of a pot, they often perform better in containers than they do in the ground. (longfield-gardens.com)
Choosing the Right Pot
Always select a container with drainage holes. A pot without holes will trap water at the bottom, which leads to root rot. If you find a decorative pot you love that doesn't have holes, you can use it as a "cachepot." This means you plant the begonia in a plain plastic nursery pot with holes and then set that pot inside the decorative one.
Design Ideas
Begonias work beautifully on their own, but they also play well with others.
- Thriller: Use an upright cane begonia or a large Rex variety in the center of the pot.
- Filler: Surround the center plant with mounded wax begonias or other shade lovers like impatiens or coleus.
- Spiller: Use trailing begonias or something like "Silver Falls" Dichondra to drape over the edges. (longfield-gardens.com)
Hanging Basket Care
Hanging baskets dry out much faster than pots sitting on the ground because they are exposed to air on all sides. On hot days, you may need to water your hanging begonias every morning. If the basket feels very light when you lift it, it is definitely time for a deep watering.
Overwintering Begonias
Since begonias are not cold-hardy in most of the United States (except for zones 9–11), they will die when the first hard frost hits. If you have a favorite plant, you can save it for next year. (longfield-gardens.com)
Saving Tuberous Begonias
Once the leaves begin to turn yellow in the fall, stop watering the plant. After the first light frost, the foliage will blacken. Cut the stems back to about an inch above the tuber. Carefully dig the tubers out of the soil.
- Dry them: Let the tubers dry in a cool, indoor spot for a few days.
- Store them: Place the clean, dry tubers in a paper bag or a box filled with peat moss or vermiculite.
- Keep them cool: Store the box in a cool, dark, and dry place (like a basement or crawl space) where temperatures stay between 40°F and 50°F.
- Replant: In the spring, you can start the cycle again!
Bringing Plants Indoors
Wax begonias and Rex begonias can often be brought inside to live as houseplants during the winter. Before the first frost, bring the pots inside and place them in a bright window. They may drop a few leaves as they adjust to the lower humidity of your home, but they will often bounce back. Reduce your watering during the winter months, as the plants grow more slowly in the house.

FAQ
Can begonias grow in full sun?
Most begonias prefer partial shade, but some varieties can handle more sun than others. Wax begonias with bronze or dark foliage are generally the most sun-tolerant. In cooler northern climates, begonias can often tolerate full sun if they are kept consistently moist and the temperatures are not extreme. In the South, they almost always require protection from the intense afternoon sun. (longfield-gardens.com)
How often should I water my begonia plant?
There is no set schedule for watering, as it depends on your weather, soil, and the size of the pot. The best method is to check the soil with your finger every day or two. If the top inch of soil feels dry, give the plant a thorough watering. If it still feels moist, wait. Remember that plants in containers and hanging baskets will dry out much faster than those planted in the ground.
Why are the leaves on my begonia turning yellow?
Yellow leaves are most often a sign of overwatering. When the soil stays too wet for too long, the roots cannot breathe, which stresses the plant. If you see yellowing, let the soil dry out completely before watering again. Yellow leaves can also occasionally be a sign of a nutrient deficiency, so ensure you are using a balanced fertilizer once a month during the growing season.
Do I need to remove dead flowers from my begonias?
It depends on the variety. Many modern hybrid begonias are "self-cleaning," meaning the old blooms fall off on their own. However, if you have large-flowered tuberous begonias, removing the faded blooms can keep the plant looking tidy and prevent the development of mold on decaying petals. Simply pinch off the flower stem where it meets the main branch. (longfield-gardens.com)
