Identifying Your Begonia Type
Before we dive into daily care, it is helpful to know which type of begonia you have. While most begonias share similar needs for warmth and drainage, their growth habits can differ. Knowing the "personality" of your plant makes care much more intuitive. For a deeper look at the group, All About Begonias is a helpful overview. (longfield-gardens.com)
Wax Begonias
These are the classic bedding plants you often see in parks and garden borders. They have succulent, waxy leaves (either green or bronze) and produce clusters of small white, pink, or red flowers. They are incredibly reliable and are often grown as annuals in most parts of the country. If you are deciding where they fit best, Where Should Begonias Be Planted for Best Results? is worth a look. (longfield-gardens.com)
Tuberous Begonias
Grown from potato-like tubers, these varieties are famous for their large, spectacular flowers. They are popular for hanging baskets and window boxes because many have a beautiful trailing habit. Unlike wax begonias, these plants go through a distinct dormant period in the winter. If you are ready to plant them, How to Plant Tuberous Begonias is a useful next step. (longfield-gardens.com)
Rex and Rhizomatous Begonias
These are primarily grown for their stunning foliage. Their leaves come in swirls of purple, silver, pink, and deep green. While they do bloom, the flowers are usually secondary to the "fancy" leaves. These are most commonly kept as year-round houseplants. For care details, How to Care for Rex Begonia Plants covers the basics. (longfield-gardens.com)
Cane-Stemmed Begonias
Often called "Angel Wing" begonias because of their long, pointed leaves, these plants grow upright on sturdy, bamboo-like stems. They can become quite tall and architectural, making them excellent floor plants for a bright room. If you want more detail, How to Grow an Angel Wing Begonia is a helpful guide. (longfield-gardens.com)
Key Takeaway: Identifying whether your begonia is grown for its flowers (Tuberous/Wax) or its foliage (Rex/Cane) helps you decide where to place it for the best visual impact. (longfield-gardens.com)
Choosing the Right Spot: Light and Temperature
The most important rule for begonia care is "Right Plant, Right Place." Because begonias are tropical in origin, they appreciate conditions that mimic a warm, dappled forest floor. If you are shopping for a shade-loving bloomer, the Non Stop Begonias collection is a strong choice. (longfield-gardens.com)
Finding the Best Light
Begonias generally prefer bright, indirect light. Think of the light as "filtered."
- Outdoors: A spot with morning sun and afternoon shade is ideal. The hot, midday sun in July can be too intense for their fleshy leaves, leading to scorched edges.
- Indoors: Place your plant near a bright window, but not directly in the path of harsh afternoon rays. An east-facing window is often the "sweet spot" for indoor begonias. (longfield-gardens.com)
Managing Temperature
Begonias love the same temperatures we do—roughly between 60°F and 75°F. They are very sensitive to the cold. If you are growing them outdoors, wait to plant them until the nights are consistently above 50°F. If a surprise late-spring frost is predicted, it is best to bring your pots inside or cover your garden beds with a light cloth. For timing based on your location, the Shipping Information page explains how Longfield Gardens schedules orders by hardiness zone, and the Hardiness Zone Map is a useful reference.

Soil and Potting Basics
Success with begonias starts from the ground up. These plants have relatively fine, delicate root systems that do not like to be "suffocated" by heavy, wet soil.
The Perfect Soil Mix
Whether you are planting in the ground or a container, drainage is the priority. Drainage simply means how fast water leaves the soil.
- For containers, use a high-quality, peat-moss-based potting mix.
- Adding a bit of perlite or vermiculite can help keep the soil airy and light.
- Avoid using heavy garden soil in pots, as it packs down too tightly and holds onto too much water. (longfield-gardens.com)
Choosing a Container
When selecting a pot, ensure it has at least one drainage hole at the bottom. Begonias actually enjoy being a little bit "snug" in their pots, so you don't need a massive container right away. A pot that is one size larger than the root ball is usually perfect. If the pot is too large, the excess soil can stay wet for too long, which is a common hurdle for new growers. If you want added peace of mind, Longfield Gardens' 100% Quality Guarantee is part of the promise behind its plants. (longfield-gardens.com)
What to Do Next:
- Check the bottom of your pots for drainage holes.
- Gently touch the soil to see if it feels light and "fluffy."
- Move your plant if you see pale, washed-out leaves, which may indicate too much direct sun. (longfield-gardens.com)
The Art of Watering Correctly
If there is one area where gardeners feel the most uncertainty, it is watering. The goal for a begonia is to keep the soil "evenly moist." This means the soil should feel like a wrung-out sponge—not dripping wet, but not bone-dry either. (longfield-gardens.com)
The Finger Test
Instead of watering on a strict schedule (like every Monday), use the finger test. Stick your finger into the soil up to the first knuckle.
- If the soil feels damp, wait a day or two and check again.
- If the top inch feels dry, it is time to give the plant a deep drink. (longfield-gardens.com)
How to Water
When you water, try to aim for the base of the plant rather than splashing the leaves. Begonias have beautiful foliage, but trapped water on the leaves can occasionally lead to powdery mildew in humid environments. If you are growing your begonia indoors, you can place the pot on a saucer filled with pebbles and a little water. This raises the humidity around the plant without making the soil too soggy. (longfield-gardens.com)
Feeding for Vibrant Growth
Begonias are moderate "feeders." During the spring and summer, when they are actively growing and blooming, they appreciate a little extra boost. (longfield-gardens.com)
Choosing a Fertilizer
A balanced, water-soluble fertilizer (often labeled as 10-10-10) works well for most types. If you are focused on getting the biggest possible blooms from your tuberous begonias, you can look for a fertilizer with a slightly higher middle number (phosphorus), which encourages flower production. (longfield-gardens.com)
The "Less is More" Approach
It is always better to under-fertilize than to over-fertilize. A good rule of thumb is to use a half-strength liquid fertilizer once every two to four weeks during the growing season. In the winter, when the plant’s growth slows down, you can stop fertilizing altogether to let the plant rest. (longfield-gardens.com)
Maintaining Your Plant’s Shape
One of the joys of gardening is watching a plant take shape. To keep your begonia looking its best, a little light grooming goes a long way. (longfield-gardens.com)
Pinching and Pruning
If your begonia starts to look a bit "leggy" (long stems with few leaves), don't be afraid to pinch it back. Simply use your thumb and forefinger to snip off the very tip of a stem, just above a leaf node (the spot where a leaf meets the stem). This encourages the plant to grow two new stems from that point, making it bushier and fuller. (longfield-gardens.com)
Deadheading
"Deadheading" is the process of removing faded flowers. Many modern begonia varieties, like wax begonias, are "self-cleaning," meaning the old flowers fall off on their own. However, for large-flowered tuberous begonias, removing the spent blooms helps the plant focus its energy on creating new buds rather than trying to make seeds. (longfield-gardens.com)
Seasonal Care and Overwintering
Since begonias are tropical perennials, they don't naturally survive a freezing winter outdoors. However, you can easily save your plants for next year. (longfield-gardens.com)
Bringing Houseplants Indoors
For Rex or Cane begonias grown in pots, simply move them inside before the first frost. They will appreciate a bright spot away from cold drafts or heating vents. During the winter, they may drop a few leaves as they adjust to the lower light levels indoors—this is normal. Just reduce your watering and wait for the new growth to appear in spring. (longfield-gardens.com)
Storing Tuberous Begonias
Tuberous begonias need a rest period. When the foliage starts to yellow in the autumn:
- Reduce watering and let the stems die back naturally.
- Gently lift the tubers out of the soil.
- Let them dry in a cool, shaded spot for a few days.
- Store them in a box of peat moss or sawdust in a cool (but not freezing) basement or closet.
- Replant them in fresh soil once the spring weather warms up. (longfield-gardens.com)
Key Takeaway: Begonias are quite resilient. Even if they look a little tired at the end of the season, a period of rest or a move indoors is often all they need to bounce back beautifully. (longfield-gardens.com)
Simple Propagation: Growing New Plants
Once you fall in love with begonias, you will likely want more of them! The good news is that they are some of the easiest plants to propagate. (longfield-gardens.com)
Stem Cuttings
This works best for wax and cane-stemmed begonias.
- Cut a 4-inch piece of a healthy stem.
- Remove the bottom leaves.
- Place the stem in a glass of water or directly into moist potting soil.
- In a few weeks, you will see new roots forming. (longfield-gardens.com)
Leaf Cuttings
This is a "magic" trick for Rex begonias. You can actually grow a whole new plant from a single leaf!
- Take a healthy leaf and cut it into small squares or wedges, ensuring each piece has a main "vein" running through it.
- Lay the pieces flat on top of moist soil and gently press them down.
- Keep the container in a warm, bright spot (covering it with a clear plastic bag helps keep the humidity high).
- Tiny new plantlets will eventually sprout from the leaf veins. It takes a little patience, but it is an incredibly rewarding process to watch. (longfield-gardens.com)
Encouraging Realistic Expectations
Gardening is a living process, and every home or yard has its own unique microclimate. Your begonia might grow a bit slower than a neighbor’s, or it might bloom two weeks later. This is perfectly normal! Factors like the amount of humidity in your air, the mineral content of your water, and the exact temperature of your windowsill all play a part. (longfield-gardens.com)
At Longfield Gardens, we have found that the most successful gardeners are the ones who observe their plants. If the leaves look a bit droopy, they check the moisture. If the stems are reaching toward the glass, they provide a bit more light. Think of your begonia as a partner in the garden; it will tell you what it needs if you take a moment to look. (longfield-gardens.com)

FAQ
How much sun does my begonia plant actually need?
Most begonias prefer bright, indirect light or dappled shade. Direct afternoon sun can be too harsh and may scorch the leaves, while too little light can cause the plant to become leggy and stop blooming. A spot with morning sun and afternoon protection is usually ideal for outdoor plants. For a quick refresher, Are Begonias Sun or Shade Plants? explains the differences. (longfield-gardens.com)
Why are the edges of my begonia leaves turning brown and crispy?
Brown, crispy edges are usually a sign of low humidity or underwatering. If the soil is dry, give the plant a thorough watering. If the soil is already moist, the air may be too dry; try placing the plant on a pebble tray with water to increase the local humidity. (longfield-gardens.com)
Do I need to cut off the old flowers on my begonias?
While many wax begonias are self-cleaning, removing spent blooms (deadheading) on tuberous varieties can encourage the plant to produce more flowers. It also keeps the plant looking tidy and prevents old petals from sitting on the leaves, which can sometimes lead to rot in very humid conditions. (longfield-gardens.com)
Can my begonia live outside all year round?
Begonias are tropical plants and cannot survive freezing temperatures. In USDA zones 9-11, they may live outdoors year-round, but in most of the United States, they must be brought indoors or have their tubers stored during the winter months. Always bring them inside before the first frost of the season. For shipping timing and zone guidance, see Shipping Information again if you need a reminder. (longfield-gardens.com)
