Introduction
There is a unique kind of excitement that comes with finding the perfect plant for a shady corner of the garden. For many of us, begonias are that "aha!" moment. These versatile plants offer a stunning array of colors, textures, and patterns that can brighten up even the dimmest porch or garden bed. Whether you are captivated by the rose-like blooms of tuberous varieties or the metallic, swirling patterns of Rex begonia foliage, there is a variety that fits your style.
At Longfield Gardens, we want to help you enjoy the rewarding experience of growing these tropical beauties, and our Begonia Flower Bulbs for Sale collection is a great place to start. They are famously generous bloomers, often providing color from late spring all the way until the first frost. While they have a reputation for being a bit particular, caring for them is actually quite straightforward once you understand their basic needs.
This guide is designed for gardeners of all levels who want to learn the best practices for begonia care. For a deeper dive, see our How Do I Care for a Begonia Plant for Success. We will cover everything from choosing the right potting mix to managing light levels and overwintering your plants so they can return for another season of beauty. Learning how to take care of a begonia plant is a journey into the world of tropical color that we are excited to share with you.
Understanding Your Begonia Type
Before you can provide the best care, it is helpful to know which type of begonia you are growing. While there are thousands of species and hybrids, most home gardeners will encounter four main categories, as explained in All About Begonias. Each has slightly different preferences, and matching your care routine to the type of plant you have is the first step toward success.
Wax Begonias (Fibrous Rooted)
These are the classic "bedding" begonias you often see in local parks and garden borders. They have waxy, succulent leaves that are either green or bronze-red. They are generally the most sun-tolerant of the group and are very easy to maintain in garden beds or window boxes.
Tuberous Begonias
Grown for their spectacular, oversized flowers, tuberous begonias are the stars of hanging baskets and patio containers, and Begonia Hanging Pink Balcony is a perfect example. Their blooms can be single or double and come in shades of neon orange, buttery yellow, soft pink, and vibrant red. Because they grow from a thick tuber, they have a distinct dormancy period in the winter.
Rex Begonias (Rhizomatous)
If you love striking foliage, Rex begonias are for you. They are primarily grown for their leaves, which can feature silver, purple, burgundy, and green in intricate patterns. For a closer look at this type, read How to Care for a Begonia Rex Plant. They prefer high humidity and are popular as houseplants or as focal points in shady container gardens.
Cane Begonias (Angel Wing)
Named for their tall, bamboo-like stems and wing-shaped leaves, cane begonias are upright growers. They often feature silver spots on their leaves and produce heavy clusters of dangling flowers. If you grow this type indoors, see How to Care for Angel Wing Begonia Plants for Better Blooms. They are exceptionally sturdy and make excellent, long-lived houseplants.
Key Takeaway Identifying your begonia type helps you provide the right care. Wax begonias love the garden border, tuberous types excel in baskets, and Rex or cane varieties are perfect for foliage-focused displays. For a ready-made selection, browse our Upright Double Begonias.
Light Requirements for Success
One of the most important parts of learning how to take care of a begonia plant is finding the right light balance. In their native tropical habitats, most begonias grow on the forest floor under a canopy of trees. This means they are adapted to "dappled" or "filtered" light rather than the harsh, direct rays of the midday sun. For more light-matching tips, see Are Begonias a Shade Plant? Find the Best Spot for Blooms.
Outdoor Light Placement
For most begonias, a spot with morning sun and afternoon shade is the ideal choice. The gentle morning light provides enough energy for blooming, while the afternoon shade protects the foliage from scorching. If you have a spot that gets about 3 to 6 hours of filtered sunlight, your begonias will likely thrive.
Bronze-leaved wax begonias are an exception; they can often handle more sun than their green-leaved relatives. However, even these benefit from a break during the hottest part of the day. If you notice the leaves turning brown and crunchy at the edges, the plant is likely getting too much direct sun.
Indoor Light Placement
If you are growing begonias as houseplants, place them near a bright window but out of the direct path of the sun. An east-facing window is often the "Goldilocks" spot—just right. If you only have south-facing windows, move the plant a few feet back from the glass or use a sheer curtain to soften the light.
Mastering the Art of Watering
Watering is the area where most gardeners feel the most uncertainty, but it doesn't have to be complicated. If you want a deeper look, read How Much Water Does a Begonia Plant Need? Expert Care Guide. The goal for begonias is to keep the soil "evenly moist." This means the soil should feel like a wrung-out sponge—damp to the touch but not dripping wet.
The Finger Test
The most reliable way to tell if your begonia needs water is to use your finger. Stick your finger about an inch or two into the soil. If the top inch feels dry, it is time to water. If it still feels cool and damp, wait a day or two and check again.
How to Water Correctly
When you water, apply it directly to the soil at the base of the plant. Avoid splashing water onto the leaves, especially if your begonias are in a spot with low air circulation. Wet leaves can lead to fungal issues like powdery mildew.
For plants in containers, always water until you see it running out of the drainage holes at the bottom. This ensures the entire root ball is hydrated and helps flush out any excess salts from fertilizers. After watering, make sure the pot is not sitting in a saucer full of water, as "wet feet" can lead to root rot.
Humidity and Airflow
Begonias love humidity, usually between 50% and 70%. In a dry home, you can increase humidity by placing the pot on a tray filled with pebbles and a little water. As the water evaporates, it creates a moist microclimate around the foliage. We recommend avoiding misting the leaves, as the moisture can sit too long and encourage disease.
What to Do Next
- Check your soil moisture every 2 to 3 days.
- Always use pots with drainage holes.
- Empty saucers 15 minutes after watering.
- Group plants together to naturally raise humidity levels.
Soil and Potting Basics
Begonias need soil that drains quickly but still holds enough moisture to keep the roots happy. For container-grown plants, see How to Care for a Potted Begonia Plant: Expert Grow Guide. In the gardening world, we call this "well-draining" soil. If you are planting in containers, a high-quality, peat-moss or coco-coir-based potting mix is usually the best choice. These materials are light and airy, allowing roots to grow easily while retaining the right amount of hydration.
Choosing the Right Container
When potting your begonias, size matters. We find that begonias actually prefer to be slightly snug in their pots. A pot that is too large can hold more water than the plant can use, which keeps the soil soggy for too long. If you are repotting, only go up one size (about 2 inches wider) at a time.
Clay or terracotta pots are excellent for begonias because they are "breathable." They allow some moisture to evaporate through the sides, which helps prevent the soil from staying too wet. If you use plastic or glazed ceramic pots, you may need to water slightly less often since they hold moisture longer.
Feeding for Continuous Blooms
Since begonias are such heavy bloomers, they appreciate a regular supply of nutrients. A bulk-blooming option like Begonia Non Stop Mix - Bulk Offer is a good example of the nonstop color that makes feeding worthwhile. Think of fertilizer as the fuel that keeps the flower show going all summer long.
Fertilizing Schedule
During the active growing season (spring through late summer), we suggest using a balanced, water-soluble fertilizer once a month. A "balanced" fertilizer is one where the three numbers on the label (nitrogen, phosphorus, and potassium) are the same or similar, such as a 10-10-10 or 20-20-20.
For varieties grown specifically for their flowers, like tuberous begonias, you can switch to a fertilizer higher in phosphorus (the middle number) once you see buds forming. This encourages more and larger blooms. Always follow the instructions on the product label for the correct dosage. It is better to use a slightly weaker solution more often than to use too much at once.
When to Stop Feeding
As the days get shorter and temperatures cool down in the fall, begonias naturally slow their growth. This is the signal to stop fertilizing. For tuberous varieties, this helps them prepare for their winter dormancy. For houseplants, it gives them a much-needed rest during the winter months.
Pruning and Pinching for Better Shape
Many begonias can become "leggy" over time, meaning they grow long, thin stems with few leaves at the base. You can easily fix this with a bit of simple pruning.
Pinching for Fullness
When your plants are young and about 6 inches tall, you can "pinch" off the very top of the growing stem. This encourages the plant to branch out from the sides, creating a bushier, fuller shape. You can do this with your fingernails or a small pair of clean scissors.
Removing Spent Blooms
"Deadheading" is the process of removing flowers that have finished blooming. While many modern wax begonias are "self-cleaning" (meaning the old flowers fall off on their own), tuberous and cane begonias benefit from a quick tidy-up. Removing old flowers prevents the plant from spending energy on seed production and keeps it focused on making new buds.
Key Takeaway Regular "pinching" when the plant is young leads to a much fuller, more attractive plant later in the season. Don't be afraid to trim—begonias are very resilient! For a showy example, see Begonia Upright Double Roseform Pink.
Moving Begonias Indoors for Winter
Because begonias are tropical plants, they cannot survive a frost. For step-by-step storage, see How to Overwinter Begonia Plants for Next Year. In most parts of the US, you will need to bring them inside or store them if you want to keep them for next year.
Transitioning Houseplants
For Rex and cane begonias that you have kept outdoors for the summer, start the transition before nighttime temperatures drop below 50°F. Bring them inside and place them in a bright spot. They might drop a few leaves as they adjust to the lower light and humidity of your home, but they will soon settle in.
Storing Tuberous Begonias
Tuberous begonias are unique because they go completely dormant. Here is the simple process we use to store them:
- Stop watering: In late summer, reduce watering to let the plant begin to die back.
- Lift the tubers: After the first light frost kills the top growth, carefully dig up the tubers.
- Clean and dry: Cut off the stems about an inch above the tuber. Let the tubers dry in a cool, shady spot for about a week.
- Storage: Place the dry tubers in a box of peat moss, sawdust, or shredded paper. Store them in a cool, dark, and dry place (around 50°F) until spring.
Simple Troubleshooting and Health Tips
Even with the best care, you might occasionally run into a few hurdles. Most begonia issues are easy to solve once you know what to look for.
Powdery Mildew
This looks like a dusting of white flour on the leaves. It usually happens when the air is damp and stagnant. To fix it, improve the airflow around your plants and try to keep the leaves dry when watering. If it persists, a simple neem oil spray or a copper-based fungicide (following label instructions) can help.
Yellowing Leaves
Yellow leaves can be a sign of a few different things. If the lower leaves are turning yellow and falling off, you might be overwatering. Let the soil dry out a bit more between waterings. If the leaves are pale yellow all over, the plant might need a bit more light or a light dose of fertilizer.
Leaf Drop
If you just moved your plant to a new spot and it drops several leaves, don't worry. This is a common "stress response" to a change in environment. Keep the care consistent, and the plant will usually grow new leaves that are better adapted to the new location.
What to Do Next
- Inspect leaves once a week for spots or pests.
- Ensure plants aren't crowded too closely together.
- Remove any fallen or dead leaves from the soil surface to keep things clean.
Propagation: Growing More for Free
One of the most rewarding parts of learning how to take care of a begonia plant is discovering how easy they are to propagate. To multiply your collection, read How to Propagate Begonia Plants: A Simple Step-by-Step Guide. You can create brand new plants from the ones you already have with just a few simple steps.
Stem Cuttings
This works best for wax and cane begonias. Cut a 4-inch piece of stem that has at least two "nodes" (the bumps where leaves grow). Remove the lower leaves and place the stem in a jar of water or a pot of moist, light soil. Within a few weeks, you will see new roots forming.
Leaf Cuttings
Rex begonias are famous for their ability to grow from just a piece of a leaf. You can take a healthy leaf, cut it into small squares (ensuring each square has a main vein), and press them into moist potting mix. Keep the tray covered with clear plastic to hold in humidity, and soon tiny "baby" begonias will sprout from the edges of the leaf pieces.
Using Begonias in Your Landscape Design
Begonias offer so much versatility that they can be used in almost any part of your yard. Their consistent blooming and interesting foliage make them a designer's favorite for adding depth and color.
Container Thrillers and Spillers
In a container, use Begonia Upright Double Bertini as a "thriller" in the center to provide height. Use trailing tuberous begonias as "spillers" to cascade over the edges of the pot. This creates a professional, layered look with very little effort.
Shady Borders
Massing wax begonias along the edge of a shaded walkway creates a clean, colorful border that lasts all season. Their uniform growth habit makes them look neat and tidy without the need for constant trimming.
Under-Tree Plantings
Because begonias handle root competition well, they are excellent for planting under large shade trees where other flowers might struggle. Just be sure to give them a little extra water, as the tree roots will be competing for moisture.

FAQ
Do begonias like sun or shade?
Most begonias prefer partial shade or filtered sunlight. While they need light to produce flowers, direct afternoon sun can scorch their leaves. Morning sun followed by afternoon shade is usually the best environment for most varieties.
How often should I water my begonia?
There is no set schedule, as watering needs change with the weather. Instead of a calendar, use your finger to check the soil; water when the top inch feels dry. Typically, this ends up being about once or twice a week for outdoor plants.
Are begonias annuals or perennials?
Begonias are tropical perennials, meaning they can live for many years in warm climates (Zones 9-11). In colder regions, they are usually grown as annuals or brought indoors as houseplants during the winter to protect them from frost. If you are not sure which zone you garden in, check our Hardiness Zone Map.
Why are my begonia leaves turning brown on the edges?
Brown, crunchy edges usually indicate either low humidity or too much direct sunlight. Try moving the plant to a shadier spot or increasing the humidity around it using a pebble tray or a humidifier. Avoid misting the leaves directly, as this can lead to other issues.
