Introduction
Shade gardens are often known for their quiet greens and varied textures, but adding a splash of high-impact color can truly transform these cool spaces. Non Stop begonias are a favorite for exactly this reason, offering brilliant, rose-like blooms that continue to appear from early summer all the way until the first frost. At Longfield Gardens, we enjoy these plants because they provide the kind of reliable, vivid color usually reserved for sun-drenched flower beds.
Whether you are looking to brighten up a covered porch with hanging baskets or want to add a vibrant edge to a shaded walkway, these begonias are an excellent choice. This guide is for home gardeners who want to learn the simple steps for starting tubers and caring for these spectacular bloomers. If you want a broader overview of the plant family, see our All About Begonias guide. By following a few basic principles, you can enjoy a season full of lush foliage and "non-stop" flowers.
Growing these beautiful plants is a rewarding experience that brings professional-looking results to any yard.
What Makes Non Stop Begonias Special
Non Stop begonias are a specific type of tuberous begonia known for their compact growth habit and exceptionally large, double flowers. While some begonias are grown primarily for their leaves, the Non Stop series is bred for maximum flower production. If you want to compare growth habits and mature size, our How Tall Do Non Stop Begonias Grow? guide is a helpful next step. The blooms can reach up to four inches across, appearing in shades of bright red, orange, yellow, pink, and white.
There are two main categories you will often see: the standard Non Stop series and the Non Stop Mocca series. The standard varieties feature bright green, wing-shaped leaves that make the flower colors pop. The Mocca varieties are prized for their deep, bronze-chocolate foliage, which provides a dramatic, dark backdrop for the vibrant blossoms. Both types share the same "non-stop" blooming habit and easy-care nature.
Because these plants grow from tubers, they have a built-in energy reserve. This makes them more resilient than many other annual flowers. They typically reach about 10 to 12 inches in height and spread, making them the perfect size for "filler" plants in mixed containers or as tidy rows in a garden border.
When to Start Your Begonia Tubers
Timing is one of the most important factors when learning how to plant Non Stop begonias. Since these are tropical plants, they are very sensitive to cold temperatures. If you want a full planting timeline from indoor start to outdoor move, see When to Plant Begonia Bulbs Indoors for Summer Blooms. However, they also take a bit of time to get going. To get the earliest possible flowers, it is best to start the tubers indoors before the weather warms up outside.
In most parts of the United States, we recommend starting your tubers indoors about 8 to 12 weeks before the last expected frost in your area. This "head start" allows the plants to develop a strong root system and their first set of leaves while it is still chilly outside. For shipping timing by region, our Shipping Information page explains how orders are scheduled by zone. By the time the soil warms up and the risk of frost has passed, your begonias will be ready to go into the ground or their outdoor pots.
If you miss the window for starting them early indoors, do not worry. You can still plant the tubers directly outdoors once the weather is consistently warm. The only difference is that your plants will likely begin blooming a little later in the summer.
Key Takeaway: Starting begonia tubers indoors in late winter or early spring ensures you get the longest possible season of blooms.
Choosing the Right Containers and Soil
Before you put your tubers in the dirt, you need to prepare the right environment. Non Stop begonias have a shallow root system and are sensitive to "wet feet," which means they do not like to sit in soggy soil. Choosing the right pot and potting mix is the first step toward success.
Selecting a Pot
For starting tubers indoors, small 4-inch pots or shallow seed trays are ideal. Each tuber only needs an inch or two of space around it. Make sure any container you use has plenty of drainage holes. For a deeper walkthrough on container prep, see How to Plant Begonias in Pots for Beautiful Blooms. Drainage refers to how fast water leaves the soil. If the water cannot escape, the tubers may rot before they even start to grow.
The Best Soil Mix
Always use a high-quality, well-draining potting soil rather than heavy garden soil. A mix that contains peat moss, perlite, or vermiculite is perfect because it holds enough moisture to keep the plant hydrated but allows excess water to drain away quickly. If you are planting in the ground later, you can improve your garden soil by mixing in some compost to lighten the texture.
Step-by-Step Guide to Indoor Planting
Planting a begonia tuber can be a little confusing because they have a unique shape. However, once you know what to look for, it is very simple.
- Identify the Top: Look at the tuber closely. One side will be slightly rounded, and the other side will have a hollow, bowl-like indentation. The hollow side is the top. This is where the stems and leaves will emerge.
- Prepare the Soil: Fill your pots or trays with potting mix and water it lightly so it is damp but not dripping wet.
- Place the Tuber: Set the tuber into the soil with the hollow side facing up. You do not need to bury it deep. In fact, many gardeners prefer to leave the top of the tuber just barely visible or covered with only a half-inch of soil.
- Space Them Out: If you are using a large tray for multiple tubers, space them about 2 to 3 inches apart.
- Provide Warmth and Light: Place the pots in a warm spot, ideally between 70°F and 75°F. They do not need much light until the first sprouts appear, but once you see green "pips" poking through, move them to a bright window or under grow lights.
What to do next:
- Check your pots every few days to ensure the soil stays moist.
- Avoid overwatering; the soil should feel like a wrung-out sponge.
- Be patient, as begonias can take 2 to 4 weeks to show their first sprouts.
Caring for Young Sprouts
Once the sprouts appear, your Non Stop begonias will begin to grow more rapidly. This is an exciting phase where the plants start to take shape. During this time, they need consistent light and careful watering.
If you are growing them on a windowsill, remember to rotate the pots every few days. Plants naturally grow toward the light, and rotating them keeps the stems straight and sturdy rather than leaning to one side. If the stems look long and "leggy," it usually means they need more light.
Watering at this stage should be done from the side of the pot. Try to avoid getting water directly into the hollow "bowl" of the tuber, as standing water in that indentation can cause the plant to decay. Instead, pour water onto the soil surrounding the tuber.
Transitioning to the Great Outdoors
Moving your begonias from the protected indoor environment to the garden is a process called "hardening off." This is a crucial step that helps the plants adjust to the wind, sun, and temperature changes of the outdoors.
Wait until the nighttime temperatures are consistently above 50°F before you think about moving them outside. Start by placing your pots in a shaded, protected spot for just a few hours a day. Gradually increase their time outside over the course of a week. For a simple guide to timing and outdoor planting, you can also read When to Plant Non Stop Begonias for a Season of Color.
This slow introduction prevents the leaves from getting "sunburned" or wind-damaged. After a week of this transition, your begonias will be tough enough to stay outside permanently. At Longfield Gardens, we find that this extra week of patience results in much healthier plants that hit the ground running.
Where to Plant: Finding the Perfect Spot
Non Stop begonias are famous for their ability to thrive in the shade, but they do have specific preferences when it comes to light. "Right plant, right place" is a core rule for gardening success.
Light Requirements
While they are called shade plants, they actually perform best in "filtered" or "dappled" light. For a closer look at ideal locations, see Where Is the Best Place to Plant Begonias?. A spot that gets gentle morning sun and shaded protection during the hot afternoon is ideal. If they are in deep, dark shade, they will still grow, but they may produce fewer flowers. If they get too much direct midday sun, the leaves may turn brown or crisp at the edges.
Protection from Wind
The stems of Non Stop begonias are succulent and can be somewhat brittle. Because they hold heavy, water-filled blooms, they can be damaged by strong gusts of wind. Choose a spot that is sheltered by a wall, a fence, or other larger plants to keep them safe during summer storms.
Air Circulation
Even though they like a sheltered spot, they still need some fresh air moving around them. Do not crowd them too tightly against other plants. Good air circulation helps keep the foliage dry and prevents common issues like powdery mildew, which looks like a dusting of white flour on the leaves.
Planting in the Garden Landscape
If you are planting your begonias directly into garden beds, proper spacing is the quiet winner for a beautiful display. For a lush, filled-in look, space your plants about 10 to 12 inches apart. This gives each plant enough room to reach its full size without competing too hard for nutrients, while still creating a solid carpet of color.
When you dig your holes, make sure they are only as deep as the root ball of the plant. If you want a more detailed look at planting depth, our How Deep Should I Plant Begonias? guide covers the basics. After placing the plant in the hole, gently firm the soil around it and water it in well to settle the roots.
Key Takeaway: Proper spacing and planting depth are the two easiest ways to ensure your begonias grow into healthy, mounded plants.
Success with Begonias in Containers
Many gardeners find that Non Stop begonias really shine when grown in pots, window boxes, and hanging baskets. Containers allow you to move the plants around to find the perfect light levels throughout the season.
Choosing a Container Role
In a mixed container, Non Stop begonias serve as an excellent "filler." Their mounded shape sits perfectly between a tall "thriller" plant (like a spike or a tall coleus) and a trailing "spiller" plant (like ivy or sweet potato vine). If you love basket planting, How to Grow Begonias in Hanging Baskets is a great companion read. They provide a solid block of color that stays at a consistent height all season.
Potting Up
If you are planting a single begonia in a pot, a 6-inch or 8-inch container is usually sufficient. If you are creating a large mixed display, you can fit three begonias into a 12-inch or 14-inch pot. Just remember that the more plants you have in one pot, the faster the soil will dry out. For a beautiful trailing option, Begonia Hanging Golden Balcony is especially useful in containers and hanging baskets.
Hanging Baskets
Non Stop begonias are heavy bloomers, and their flowers often face slightly outward or downward. This makes them look beautiful in hanging baskets where the flowers are at eye level. Make sure your basket is hung in a spot where it won't be whipped around by the wind.
Watering and Fertilizing for Continuous Blooms
To live up to their name, Non Stop begonias need a steady supply of moisture and nutrients. However, "steady" does not mean "constant."
The Right Way to Water
The goal is to keep the soil evenly moist, like a sponge that has been wrung out. The best way to check is to stick your finger about an inch into the soil. If it feels dry, it is time to water. If it still feels damp, wait another day.
When you water, try to keep the moisture off the leaves and flowers. Water at the base of the plant early in the morning. This allows any accidental splashes on the leaves to dry up during the day, which reduces the chance of fungal issues.
Feeding Your Plants
Because begonias bloom so much, they use up a lot of energy. Feeding them every 2 to 3 weeks with a balanced, water-soluble fertilizer will keep them strong. For more general care guidance, see How to Care for Begonia Plant. Look for a fertilizer where the three numbers on the label are roughly equal (like 10-10-10). Avoid high-nitrogen fertilizers (where the first number is much higher), as this can lead to lots of green leaves but very few flowers.
What to do next:
- Check container plants daily during hot weather, as pots dry out faster than garden beds.
- Use a watering can with a long spout to reach the soil under the leaves.
- If the plant looks yellow or pale, it might be a sign it needs a little more fertilizer.
Maintenance and Deadheading
One of the best things about Non Stop begonias is that they are relatively low-maintenance. Unlike some other annuals, they are "self-cleaning." This means that as the flowers finish blooming, they naturally drop off the plant on their own.
You do not strictly need to "deadhead" (remove old flowers) to keep the plant blooming. However, some gardeners like to pick up the fallen petals from the top of the soil or the leaves to keep the garden looking tidy. If a stem gets too long or the plant starts to look a bit "leggy" in mid-summer, you can gently pinch off the growing tips to encourage the plant to branch out and become bushier.
Common Challenges and Easy Wins
Most people find that Non Stop begonias are very easy to grow, but every plant can run into a few hurdles. Knowing what to look for makes troubleshooting simple.
If you notice the stems turning soft or mushy at the base, the most likely cause is overwatering. The simplest fix is to let the soil dry out significantly before the next watering and ensure your pot has clear drainage holes.
If you see a white, powdery substance on the leaves, this is powdery mildew. It often happens when the air is humid and still. To help the plant, you can move it to a spot with better air circulation or space your plants a bit further apart next season.
If the leaves look pale or the plant isn't blooming much, it probably needs a bit more light or a boost of fertilizer. Try moving it to a slightly brighter spot (but still out of harsh direct sun) and see how it responds over the next week or two.
Saving Tubers for Next Year
While many people treat Non Stop begonias as annuals, you can actually save the tubers and replant them next spring. This is a great way to grow your garden without having to buy new plants every year.
When the weather starts to cool down in the fall and the leaves begin to turn yellow, stop watering the plants. After the first light frost kills the top growth, carefully dig up the tubers. Cut off the stems about an inch above the tuber and gently brush off the excess soil.
Let the tubers sit in a dry, shady spot indoors for a few days to "cure." Once they are dry to the touch, wrap them in newspaper or store them in a box of dry peat moss or sawdust. Keep the box in a cool, dark, and frost-free place, like a basement or a closet. Next spring, about 8 to 12 weeks before the last frost, you can take them out and start the process all over again.
Creating Beautiful Combinations
Because Non Stop begonias come in so many vibrant colors, they are a lot of fun to pair with other plants. For a classic, elegant look, try planting white Non Stop begonias alongside silver-leaved plants like Dusty Miller or dichondra.
For a high-energy, tropical feel, combine orange and yellow begonias with dark purple coleus or ornamental sweet potato vines. The contrast between the bright flowers and the dark foliage makes the colors seem even more intense.
In the garden border, begonias look wonderful when planted in front of taller shade-lovers like hostas or ferns. If you are thinking about companion planting in baskets, What to Plant With Begonias in Hanging Baskets offers even more ideas. The begonias provide the color, while the larger plants provide a lush green backdrop. No matter how you choose to use them, these plants are sure to be a highlight of your summer garden.
Conclusion
Planting Non Stop begonias is one of the easiest ways to bring consistent, brilliant color to the shaded areas of your yard. By starting your tubers early indoors, providing well-drained soil, and finding a spot with filtered light, you can enjoy a spectacular show of double blooms from early summer until the first frost. These plants are resilient, low-maintenance, and incredibly rewarding for gardeners of all skill levels.
- Start tubers indoors 8-12 weeks before the last frost for the longest bloom season.
- Always plant the tuber with the hollow, indented side facing up.
- Provide bright, filtered light and avoid the harsh midday sun.
- Water the soil, not the leaves, to keep the plants healthy and rot-free.

FAQ
Which way is up when planting a begonia tuber?
The tuber has a slightly rounded side and a hollow, bowl-like side. You should always plant the tuber with the hollow side facing up, as this is where the new stems will grow.
Can Non Stop begonias grow in full sun?
While they can handle a little morning sun, they generally prefer partial shade or filtered light. If you want to see how light affects placement, our Where Is the Best Place to Plant Begonias? guide is a helpful reference. In very hot climates, full midday sun can scorch their leaves and cause the flowers to wilt prematurely.
How often should I water my begonias?
You should water whenever the top inch of soil feels dry to the touch. This might be every day for plants in hanging baskets during a heatwave, or every few days for plants in the ground.
Do I need to remove the dead flowers?
Non Stop begonias are self-cleaning, so they will naturally drop their old flowers. While you do not need to deadhead them to keep them blooming, you can tidy up the fallen petals if you prefer a cleaner look.
