Introduction
Begonias are among the most versatile plants you can bring into your life. They offer a stunning range of colors, textures, and sizes that can brighten up a dim corner of your living room or add a lush, tropical feel to your patio. At Longfield Gardens, we enjoy how these plants effortlessly bridge the gap between the garden and the home. Whether you are looking for massive, rose-like blooms or intricate, metallic-patterned foliage, there is a begonia that fits your vision.
This guide is designed for home gardeners who want to understand the best ways to grow begonias both indoor and outdoor. We will cover which varieties thrive in each setting and how to transition them between spaces as the seasons change. By the end of this article, you will have a clear plan for keeping your begonias healthy and vibrant all year round. Growing begonias is a rewarding experience that brings professional-looking results to any skill level.
Can Begonias Grow Both Indoors and Outdoors?
The short answer is yes. Begonias are technically tropical perennials. This means they naturally grow in warm, humid environments where they live for many years. In most parts of the United States, we treat them as annuals when they are outside because they cannot survive a frost. However, their tropical nature makes them excellent candidates for life as houseplants.
The choice between growing begonias indoor or outdoor usually depends on your climate and the specific variety of begonia you have. Some types are prized for their outdoor flower displays, while others are kept indoors for their spectacular leaves. Many gardeners choose to do both. You might start your begonias in pots on a shaded porch for the summer and move them inside to a bright window when the autumn air turns crisp.

Understanding the Four Main Begonia Types
To decide where to place your plant, you first need to know what kind of begonia you are growing. While there are thousands of species, most garden center varieties fall into four main categories. Each has slightly different preferences for light and temperature.
Tuberous Begonias
Tuberous begonias are famous for their large, dramatic flowers. These blooms can look like roses, camellias, or carnations and come in brilliant shades of red, orange, pink, yellow, and white. Because they grow from a thick, potato-like underground stem called a tuber, they have a distinct growing cycle.
These are most often grown as outdoor stars in hanging baskets or containers. They love the fresh air and filtered light of a porch. While they can be grown indoors, they require very specific light and humidity to bloom well inside, so they are generally seen as the "outdoor" choice for summer color. For a popular upright variety, try Begonia Upright Double Roseform Pink.
Wax Begonias
Wax begonias are the classic bedding plants seen in many garden borders. They have succulent-like, waxy leaves that are either green or bronze. They produce clusters of small, four-petaled flowers all season long.
Wax begonias are incredibly tough. They are one of the few types that can handle more sun than their cousins. While they are staples for the outdoor landscape, they also make very easy-care houseplants. If you dig them up before the first frost, they will often continue blooming on a sunny windowsill throughout the winter.

Rex Begonias
Rex begonias are grown primarily for their foliage. Their leaves are works of art, featuring swirls of silver, purple, burgundy, and emerald green. Many have a unique "snail" shape where the leaf curls in on itself at the stem.
Because Rex begonias naturally grow on the forest floor, they are highly sensitive to direct sun. This makes them the ultimate indoor begonia. They thrive in the indirect light of a home. Outdoors, they must be kept in full, deep shade, or their delicate leaves will scorch. For a deeper look at foliage types, see How to Grow Rex Begonia for Stunning Foliage.
Cane Begonias (Angel Wing)
Cane begonias get their name from their tall, bamboo-like stems. The most famous sub-type is the Angel Wing begonia, named for its long, pointed leaves that often feature silver spots. These plants produce drooping clusters of flowers that look like delicate grapes.
Cane begonias are very adaptable. They grow into impressive upright specimens in outdoor large pots, but they are also legendary houseplants that can live for decades. They are sturdy, reliable, and handle the lower humidity of a typical home better than Rex begonias. If you are planning a container display, How Many Begonia Plants Per Pot? is a helpful next step.
Key Takeaway: Match the begonia type to your location. Choose Tuberous for big outdoor blooms, Rex for indoor artistic foliage, and Wax or Cane for easy transitions between both.
Growing Begonias in Your Outdoor Garden
When planting outdoors, the most important rule is to wait for the right temperature. Begonias are sensitive to cold soil and chilly nights. We recommend waiting to plant them outside until the nighttime temperatures are consistently above 50°F.
Choosing the Right Spot
"Right plant, right place" is the golden rule for begonias. Most varieties prefer "dappled" or "filtered" sunlight. This means the light that peeks through the leaves of a tall tree.
- Tuberous Begonias: They need plenty of light to produce those big flowers, but direct afternoon sun will wilt them. An east-facing spot that gets morning sun and afternoon shade is perfect.
- Wax Begonias: If you have a sunnier spot, choose bronze-leafed wax begonias. The darker pigment in their leaves acts like a natural sunscreen.
- Rex Begonias: Keep these in the deepest shade you have, such as under a covered patio or on the north side of your house.
If you want a broader guide to location, Where to Plant Begonias: Sun or Shade? covers the basics well.
Soil and Drainage
Drainage describes how fast water leaves the soil. Begonias have "succulent" stems, which means they hold a lot of water. If the soil stays soggy, the stems and roots will rot quickly.
- Use a high-quality potting mix for containers.
- If planting in the ground, ensure the soil is loose and rich in organic matter, like compost.
- Avoid heavy clay soil that holds water like a sponge.
For a more complete overview, see How to Plant and Care for Begonias.
Watering and Feeding
Outdoor begonias in pots dry out faster than those in the ground. Check the soil with your finger every day during hot weather. If the top inch feels dry, it is time to water.
For feeding, begonias are "heavy feeders." This means they need regular nutrients to keep blooming and growing. Use a balanced, water-soluble fertilizer every two weeks during the summer. This provides the energy they need to produce non-stop color until the fall.
What to do next: Outdoor Success
- Wait for warm nights (above 50°F) before moving plants outside.
- Pick a spot with morning sun and afternoon shade for best blooming.
- Ensure your pots have drainage holes so the roots don't sit in water.
- Apply a liquid fertilizer every 14 days to keep the flowers coming.
Success with Begonias as Houseplants
Growing begonias indoor allows you to enjoy their beauty regardless of the weather outside. While they are relatively easy to care for, they do have a few specific preferences when they live inside your home.
Light Requirements Indoors
Inside a house, "bright indirect light" is the goal. This usually means placing your begonia near a window that gets lots of light but where the sun's rays do not directly hit the leaves. A window with a sheer curtain is an excellent spot.
If your begonia starts to look "leggy" (long, thin stems with few leaves), it is likely trying to reach for more light. If the leaves develop brown, crispy spots, it might be getting too much direct sun. For more on indoor placement, read Are Begonias Indoor or Outdoor Plants?.
Managing Humidity
One of the biggest challenges for indoor begonias is dry air, especially during the winter when the heater is running. Rex begonias, in particular, love humidity.
- You can increase humidity by grouping plants together.
- Place the pot on a tray filled with pebbles and a little water (ensure the pot sits on the pebbles, not in the water).
- Avoid misting the leaves directly, as this can encourage powdery mildew, which looks like a dusting of white flour on the foliage.
Potting and Soil
Indoor begonias prefer to be slightly "root-bound," which means they like their roots to feel a bit snug in the pot. When it is time to repot, only go up one size. Use a potting mix that contains plenty of peat moss or perlite to ensure the soil stays light and airy.
Indoor Watering Routine
Indoor plants do not dry out as fast as outdoor ones. Always check the soil before adding water. Stick your finger an inch into the soil; if it feels damp, wait a few more days. Overwatering is the most common reason indoor begonias fail, so it is better to let the soil dry out slightly than to keep it constantly wet.
Key Takeaway: For indoor begonias, light and drainage are more important than a strict watering schedule. Always check the soil before you pour.
Moving Your Begonias Between Indoor and Outdoor Spaces
Many gardeners enjoy the "best of both worlds" by moving their plants seasonally. This gives the plants a boost of vigorous growth during the summer and protects them during the winter.
Moving Outdoors in Spring
When moving a begonia from your living room to your porch, you must do it gradually. This process is called "hardening off." If you move a plant directly from a dim room into the bright outdoors, the leaves will likely burn and fall off.
- Start by placing the plant in a fully shaded, sheltered spot for a few hours a day.
- Gradually increase the time it spends outside over 7 to 10 days.
- Slowly introduce it to the dappled sunlight it will live in for the summer.
For timing and placement details, When Do You Plant Begonias? is a useful follow-up.
Moving Indoors in Autumn
The transition back inside should happen before the temperatures drop too low. Most begonias start to stress when temperatures hit 45°F.
- Inspect the plants thoroughly for any hitchhiking insects.
- Give the leaves a gentle rinse with water to remove dust and pests.
- Trim back any overly long or "leggy" stems to make the plant more manageable.
- Expect the plant to drop a few leaves as it adjusts to the lower light levels of your home. This is a normal part of the transition.
If you want help choosing the best light level, see Do Begonias Grow in Sun or Shade?.
Seasonal Care and Overwintering
If you are growing Tuberous begonias, they have a natural resting phase. As the days get shorter in the fall, the plant will stop blooming and the leaves will begin to yellow. This is not a sign of failure; the plant is simply getting ready for its winter nap.
Storing Tuberous Begonias
When the foliage dies back, stop watering and let the soil dry out. Once the stems fall away, you can gently dig up the tuber.
- Shake off the excess soil.
- Store the tubers in a cool, dry place inside a box of peat moss or shredded paper.
- In the spring, about 6 to 8 weeks before the last frost, you can restart them in pots indoors.
Winter Care for Non-Tuberous Types
Wax, Rex, and Cane begonias do not go dormant, but their growth will slow down significantly in the winter. During this time:
- Reduce watering, as the plant is not using as much moisture.
- Stop fertilizing until you see new growth start in the spring.
- Keep them away from cold drafts or heat vents.

Simple Care Tips for Healthy Begonias
Success with begonias comes down to a few basic habits. If you get the light and water right, these plants are incredibly forgiving and rewarding.
Pruning and Grooming
Begonias look their best when they are "groomed" regularly. This simply means removing any spent flowers or yellowing leaves. For Cane begonias, you can "pinch" the growing tips. Using your thumb and forefinger, snip off the very end of a new branch. This encourages the plant to grow more side branches, making it look bushier and fuller rather than tall and spindly.
Choosing the Right Pot
The material of your pot matters.
- Terra cotta (clay) pots are breathable and allow moisture to evaporate through the walls. These are great if you tend to overwater.
- Plastic or glazed ceramic pots hold moisture longer. These are better for Rex begonias that love a bit more consistent humidity. Whatever you choose, make sure there are holes in the bottom. Drainage is the most important factor for begonia health.
Troubleshooting Made Easy
If your begonia isn't looking its best, check these three things in order:
- The Soil: Is it bone dry or soaking wet? Adjust your watering.
- The Light: Are the leaves scorched (too much sun) or is the plant reaching and thin (too little sun)? Move the pot.
- The Air: Is it very dry or is there no airflow? Use a pebble tray for humidity or move the plant away from a stagnant corner.
For broader troubleshooting, What Type of Plant Is a Begonia? gives a useful overview.
What to do next: Simple Maintenance
- Pinch back stems in the spring to encourage a bushy shape.
- Remove dead flowers to keep the plant looking tidy and prevent mold.
- Switch to a larger pot only when you see roots coming out of the bottom holes.
- Stop fertilizing in the winter to let the plant rest.

FAQ
Can I grow outdoor begonias as houseplants?
Yes, most begonias sold for the garden can live indoors. Wax begonias and Cane begonias (Angel Wing) are the easiest to transition. To do this, dig them up before the first frost, pot them in fresh potting soil, and place them in a bright window with indirect light.
Why are my begonia leaves falling off?
The most common reason for leaf drop is a sudden change in environment or improper watering. If you just moved the plant from outside to inside, it may drop leaves as it adjusts to lower light. If the plant hasn't moved, check the soil; both extremely dry soil and soggy, waterlogged soil can cause leaves to fall. For extra help, see Are Begonias Indoor or Outdoor Plants?.
How much sun do begonias actually need?
Most begonias prefer filtered light or partial shade. Tuberous and Wax begonias thrive with 4 to 6 hours of morning sun followed by afternoon shade. Rex begonias are much more sensitive and should be kept in full shade outdoors or bright, indirect light indoors to avoid burning their decorative leaves. For a quick reference, Do Begonias Grow in Sun or Shade? can help.
Do I need to deadhead my begonias?
While many modern begonias are "self-cleaning" (meaning the old flowers fall off on their own), it is still helpful to remove spent blooms. Deadheading helps the plant look tidy and prevents fallen petals from sitting on the leaves, which can sometimes lead to fungal issues in humid weather.
