Introduction

There is a special kind of magic that happens when you find a plant that turns a quiet, shady corner into a vibrant display of color. For many of us, the Non Stop begonia is that perfect choice. These plants are famous for their lush, rose-like flowers and their ability to bloom continuously from early summer right through the first frost. Whether you are filling a hanging basket or lining a garden path, these begonias live up to their name by providing a steady supply of beauty with very little fuss.

At Longfield Gardens, we want to help you enjoy the rewarding experience of growing these spectacular flowers from Non Stop begonia tubers. While they might look like simple brown discs at first, these tubers hold all the energy needed to produce a season of stunning growth. This guide will walk you through everything you need to know about how to plant Non Stop begonia tubers. We will cover starting them indoors, moving them to the garden, and providing the simple care they need to thrive.

Growing begonias is an accessible and enjoyable way to enhance your outdoor living space. By following a few basic steps, you can ensure your tubers get off to a healthy start and continue blooming all summer long. This article is designed for gardeners of all skill levels who want to master the art of planting and caring for this beloved flower variety.

Understanding Non Stop Begonias

Non Stop begonias are a specific type of tuberous begonia (Begonia tuberhybrida) known for their compact habit and prolific flowering. Unlike some other varieties that may have a lull in blooming during the hottest part of summer, the Non Stop series is bred to keep producing new buds regardless of the day length. This makes them incredibly reliable for maintaining consistent color in your landscape.

These plants typically grow about 8 to 12 inches tall, making them ideal for many different garden roles. They have a mounded growth habit that looks just as good in a window box as it does in a formal garden bed. One of the most striking features of Non Stop begonias is the variety of colors available. You can find them in brilliant shades of red, orange, yellow, pink, and white. Some varieties, like the "Mocca" series, even feature dark, chocolate-colored foliage that makes the bright flower colors pop.

Because they grow from tubers, these begonias are perennials in very warm climates, but most US gardeners grow them as annuals. The tuber acts as a storage unit for the plant, keeping nutrients tucked away during the winter months. When you plant them in the spring, you are essentially "waking up" the plant so it can begin its next cycle of growth.

Choosing the Right Time to Plant

Timing is one of the most important factors when it comes to begonia success. Because these are tropical plants, they are very sensitive to cold temperatures. They do not tolerate frost, and even a chilly night can set back their growth. For this reason, we recommend waiting until the danger of frost has completely passed and nighttime temperatures are consistently above 50°F before moving them outdoors in your hardiness zone.

Many gardeners choose to give their begonias a head start by beginning the planting process indoors. Starting your tubers about eight weeks before the last expected frost in your area allows the plants to develop leaves and roots in a protected environment. By the time the weather is warm enough to move them outside, you will already have established plants that are ready to begin blooming much sooner than if you had waited to plant them directly in the ground.

If you prefer to plant directly into the garden or outdoor containers, wait until the soil has warmed up. In most regions, this happens in late May or early June. Using a soil thermometer can take the guesswork out of the process; you are looking for a soil temperature of at least 60°F.

Preparing Your Begonia Tubers

When you first receive your Non Stop begonia tubers, you will notice they have a distinct shape. They look like small, brown, slightly hairy bowls. One side is rounded, and the other side has a hollow or cupped depression. Knowing which end is up is the first step toward successful planting.

The hollow, indented side is the top of the tuber. This is where the sprouts will emerge. The rounded side is the bottom, where the roots will eventually grow. If you look closely at the hollow side, you may already see tiny pink or red bumps. These are the "eyes" or growth points. If your tubers haven't started showing these bumps yet, you can encourage them to wake up by placing them in a warm (about 70°F) spot with indirect light for a week or two before planting.

Key Takeaway: Identifying the Top Always plant begonia tubers with the hollow, bowl-shaped side facing up. This ensures the sprouts can reach the light easily while the roots grow downward into the soil.

How to Start Tubers Indoors

Starting your Non Stop begonias indoors is a great way to enjoy blooms earlier in the season. You don’t need a greenhouse to do this successfully; a bright windowsill or a spot under grow lights works perfectly.

Select Your Containers

You can start tubers in small individual pots (about 4 to 6 inches wide) or in shallow trays. Make sure whatever container you use has plenty of drainage holes. Begonias do not like to sit in soggy soil, so the ability for excess water to escape is essential.

Use High-Quality Potting Mix

Choose a light, well-draining potting mix. Avoid using heavy garden soil, which can pack down too tightly and suffocate the young roots. A mix that contains peat moss or coco coir along with perlite is usually ideal for providing the right balance of moisture retention and aeration.

Planting Depth and Spacing

Fill your containers with moist potting mix, leaving about an inch of space at the top. Place the tuber in the center with the hollow side facing up. Press it gently into the soil. You only need to cover the tuber with about half an inch to an inch of soil. If you are using a tray to start multiple tubers, space them about 2 to 3 inches apart so their roots have room to expand without getting tangled.

Light and Water

Once planted, place the pots in a warm room with bright, indirect light. Water sparingly at first. The goal is to keep the soil slightly moist but never wet. Overwatering a tuber before it has developed roots can lead to rot. Once you see green sprouts appearing, you can begin to water a bit more regularly as the plant grows and starts to use more moisture.

Selecting the Ideal Outdoor Location

Once the weather warms up, it is time to find the perfect home for your Non Stop begonias. These plants are famous for their love of shade, but "shade" can mean different things. For the best results, aim for a spot that receives filtered light or gentle morning sun.

Sunlight Requirements

Non Stop begonias thrive in areas that get about four hours of morning sun followed by shade in the afternoon. The intense midday and afternoon sun in many parts of the US can be too hot and may scorch the leaves or cause the delicate flowers to wilt. If you live in a particularly hot climate, a spot under a high-canopy tree or on a north-facing porch is often the best choice.

Soil and Drainage

If you are planting in garden beds, the soil must be rich in organic matter and drain well. You can improve your garden soil by mixing in some compost or aged manure before planting. This adds nutrients and helps the soil stay loose so roots can spread easily. For container planting, always use fresh potting soil rather than soil from the garden.

Protection from Wind

The stems of tuberous begonias are somewhat brittle and juicy. This makes them susceptible to damage from strong winds. Choosing a location that is somewhat protected, such as near a fence, a wall, or surrounded by other plants, will help keep your begonias looking their best all season.

Moving Begonias Outdoors

The transition from the cozy indoors to the unpredictable outdoors should be a gradual one. This process is known as hardening off. If you move a plant directly from a 70°F room into the bright sun and wind, it may experience shock, which can stall its growth.

The Hardening Off Process

Start by placing your pots in a shaded, sheltered spot outside for just a few hours during the day. Bring them back inside at night. Over the course of 7 to 10 days, gradually increase the amount of time they spend outside and the amount of light they receive. This allows the plant tissues to toughen up and get used to the movement of the air and the intensity of the sun.

Final Transplanting

Once your plants are acclimated and the nights stay above 50°F, you can move them to their permanent homes.

• In the Garden: Space the plants about 8 to 12 inches apart. This gives them enough room to grow to their full size while still allowing for good air circulation between the plants.
• In Containers: A single Non Stop begonia is often happy in an 8-inch pot. If you are using a larger 12-inch container, you can plant three begonias together for a full, lush look.

What to Do Next:

• Check the 10-day weather forecast for stable nighttime temperatures.
• Begin the hardening off process by moving plants to a porch for 2 hours daily.
• Gradually increase outdoor time by 1-2 hours each day.
• Prepare your garden beds or decorative pots with fresh soil and compost.

Watering and Feeding for Continuous Blooms

Proper watering and nutrition are the keys to keeping your begonias "non stop" throughout the summer. Because these plants have thick, succulent stems, they store some water, which makes them a bit more resilient than thin-leaved plants. However, they still need a consistent schedule.

How to Water Correctly

The best rule of thumb for begonias is to let the top inch or two of soil dry out before watering again. Stick your finger into the soil; if it feels dry, it is time to water. When you do water, do so deeply until water runs out of the bottom of the pot or the ground is thoroughly soaked. This encourages the roots to grow deep into the soil. Try to water at the base of the plant rather than over the leaves. Wet foliage can sometimes lead to mildew or other fungal issues, especially in humid weather.

Fertilizer Basics

Flowering takes a lot of energy. To help your begonias produce those big, beautiful blooms all season, we recommend a regular feeding schedule. Use a balanced, water-soluble fertilizer formulated for flowering plants.

A good strategy is to use a "weak" solution—about a quarter of the recommended strength—every time you water, or a full-strength dose every two to three weeks. If you notice the leaves becoming very dark green but no flowers appearing, you may be using too much nitrogen. In that case, switch to a fertilizer with a higher middle number (phosphorus) to encourage bloom production.

Maintenance and General Care

One of the reasons we love Non Stop begonias is that they are relatively low-maintenance. They are often "self-cleaning," meaning the old flowers will drop off on their own as they fade. However, a little bit of grooming can keep the plants looking tidy and healthy.

Deadheading and Grooming

While not strictly necessary for new blooms, removing spent flowers and any yellowing leaves helps improve air circulation around the plant. This simple task keeps the plant focusing its energy on new growth rather than maintaining old tissue. It also reduces the chances of mold developing on fallen petals that might get stuck in the foliage.

Staking Large Blooms

Sometimes, the flowers on Non Stop begonias can become so large and heavy that the stems begin to lean. For more large-bloomed options, see our Upright Double Begonias. A small bamboo stake and a loose tie can help keep the stems upright. Be careful not to tie them too tightly, as the stems are soft and can be easily bruised.

Air Circulation

Good airflow is vital for begonias, especially in the humid summer months. If plants are crowded too closely together, they can become susceptible to powdery mildew, which looks like a white dusting on the leaves. If you see this, simply thin out the plants or move your containers to a spot with a bit more breeze.

End-of-Season Care and Storage

As the summer winds down and the first frost approaches, you have a choice to make. You can treat your begonias as annuals and simply compost them, or you can save the tubers to plant again next year. Saving tubers is a rewarding way to build your garden collection over time.

Lifting the Tubers

When the leaves begin to yellow in the fall, or after the first light frost has nipped the foliage, it is time to lift the tubers. Start by cutting the stems back to about an inch or two above the soil. Carefully dig up the tubers, taking care not to nick or bruise them.

Cleaning and Drying

Gently brush off any excess soil, but do not wash them with water. Place the tubers in a warm, dry, and shaded spot for a few days to "cure." This allows the outer skin to toughen up and any remaining stem pieces to dry up and fall off naturally.

Storage Conditions

Once cured, store the tubers in a cool, dark, and dry place that stays around 40-50°F. A basement or an unheated closet often works well. You can place them in a cardboard box filled with peat moss, sawdust, or even tucked into individual paper bags. Check on them once a month during the winter to make sure they aren't shriveling up or showing signs of rot. If they look very dry, a tiny mist of water can help, but generally, they should stay dry until spring.

Creating Beautiful Combinations

Non Stop begonias are wonderful on their own, but they also play well with others. Their vibrant colors and soft textures make them excellent partners for a variety of shade-loving plants. When planning your garden beds or containers, consider the "filler, thriller, spiller" method.

• As a Filler: Non Stop begonias are the perfect "filler" because of their mounded shape. They look great planted around a "thriller" like a tall Coleus or a Dracaena spike.
• With Foliage Plants: Pair bright orange or red begonias with the silver leaves of Dusty Miller or the lime-green foliage of certain Hostas. The contrast in color and leaf shape creates a sophisticated look.
• In Hanging Baskets: Begonia Hanging Golden Balcony While most Non Stops are upright, they look beautiful when surrounded by "spillers" like Bacopa, Creeping Jenny, or trailing Lobelia. These companion plants will soften the edges of the container while the begonias provide the main focal point.

By mixing and matching different colors and textures, you can create a professional-looking display that stays beautiful all summer. Remember to group plants that have similar water and light needs so they can all thrive together.

FAQ

Which side of the begonia tuber should face up when planting?

The tuber should be planted with the hollow, indented side facing up. This cupped area is where the new stems and leaves will emerge, while the rounded bottom side is where the roots will develop. If you see small pink or red bumps, those are the growth points and should always point toward the sky.

How deep should I plant Non Stop begonia tubers?

Whether you are starting them in pots indoors or planting them directly in the garden, begonias should be planted about 1 inch deep. You want just enough soil over the top of the tuber to keep it moist and protected, but not so much that the young sprouts struggle to reach the surface.

Can Non Stop begonias grow in full sun?

While they are more heat-tolerant than some other begonia types, Non Stop begonias generally prefer partial shade. They do best with about four hours of morning sun followed by afternoon shade. For more on begonia light needs, see our Where to Plant Begonias: Sun or Shade? guide.

Why are my begonia stems breaking so easily?

Begonia stems are succulent and somewhat brittle, which makes them susceptible to breaking if they are handled roughly or exposed to high winds. To prevent damage, plant them in a sheltered location and consider using small bamboo stakes for support if the flower heads become very large and heavy.
