Introduction
Few flowers can match the sheer, vibrant impact of a Non Stop begonia in full bloom. These plants are beloved for their lush, double flowers and their ability to brighten up the shadiest corners of the porch or patio. At Longfield Gardens, we see how much joy these begonias bring to gardeners who want high-impact color without the need for full sun. While they are often grown in outdoor containers, many people wonder if they can enjoy that same beauty inside their homes.
This article focuses on the specific needs of the Non Stop series when grown or kept indoors. We will cover how to create the right environment for them, how to manage their unique life cycle, and how to successfully overwinter their tubers so they return year after year. Whether you are bringing a favorite plant in from the garden or starting new tubers on a sunny windowsill, these simple steps will help you succeed.
Growing begonias is a rewarding way to add living color to your indoor space. With a little understanding of their natural rhythms, you can keep these spectacular plants healthy and vibrant for many seasons to come.
Can You Keep Begonias Inside Year-Round?
If you are asking, "can you keep begonias inside?" the answer is a definite yes, but with an important distinction. Not all begonias behave the same way once they move indoors. While some varieties thrive as permanent houseplants, others, like the tuberous Non Stop series, follow a seasonal clock that requires a rest period.
Whether a begonia can stay inside all year depends on its type. Foliage-heavy varieties and certain upright types can decorate your shelves for years without a break. However, tuberous begonias are like marathon runners; they put so much energy into their spectacular blooms during the summer that they eventually need to go dormant to "recharge" their tubers. Understanding which type you have is the first step toward long-term success.
Choosing the Right Begonia for Your Home
To get the most out of keeping begonias indoors, it helps to match the plant to your specific goals. While we love the high-impact color of Non Stop tuberous begonias, other groups offer different benefits for the indoor gardener.
- Begonia rex and Rhizomatous Begonias: These are the superstars of the indoor foliage world. Begonia rex is prized for its swirling patterns and metallic colors, while rhizomatous begonia varieties offer interesting leaf shapes and textures. These types grow from thick stems that creep along the soil surface and can live indoors year-round without a dormancy period.
- Cane-stemmed begonia (including Angel wing begonia): These are some of the easiest begonias to keep inside long-term. An angel wing begonia is easily identified by its long, spotted leaves and upright, bamboo-like stems. They can grow quite large and produce beautiful clusters of drooping flowers.
- Begonia x hiemalis (Elatior or Christmas Begonias): Often found in flower shops, these are semi-tuberous begonias that bloom during the winter months. They provide a wonderful splash of color when other plants are resting, though they are often treated as short-lived gift plants.
- Fibrous or Wax Begonias: Commonly seen in garden beds, these can be potted up and brought inside. They are tough and will continue to bloom on a sunny windowsill, though they may become a bit leggy over time.
- Tuberous Non Stop Begonias: As we discuss throughout this guide, these offer the most dramatic flowers but are seasonal. They are best for gardeners who want a show-stopping summer display followed by a quiet winter storage period.
Understanding the Non Stop Begonia
Non Stop begonias belong to the tuberous begonia family (Begonia x tuberhybrida). The name "Non Stop" refers to their incredible ability to produce flowers continuously from early summer right through the first frost. They are famous for their large, rose-like double blooms and a mounded growth habit that looks fantastic in pots and hanging baskets.
Unlike some other houseplants, such as Rex begonias which are grown for their foliage, Non Stop begonias are focused on flower production. This means they have higher energy requirements and follow a distinct seasonal cycle. They grow from a thick, brown, potato-like structure called a tuber. This tuber acts as a storage unit for energy, allowing the plant to go dormant in the winter and regrow in the spring.
Varieties to Look For
When choosing plants, you will likely see two main types in the Non Stop family. The standard Non Stop series features bright green foliage that contrasts beautifully with its flowers. The Non Stop Mocca series offers the same brilliant flower colors but with deep, chocolate-bronze leaves. Both types perform similarly indoors, though the dark-leaved Mocca varieties often handle slightly more light than the green-leaved types. We offer a variety of these tubers to help you get started with the specific colors that fit your home decor.
The Role of the Tuber
The most important thing to know about Non Stop begonias is that they are not year-round houseplants in the traditional sense. Because they are tuberous, they have a biological "clock" that tells them to rest during the winter. You can grow them indoors as a blooming plant during their active phase, but they will eventually need a period of dormancy to stay healthy in the long run.
Creating the Ideal Indoor Environment
To grow a Non Stop begonia indoors, you need to mimic the dappled light and humid air of its native tropical mountain habitats. While our homes are generally comfortable for us, they can sometimes be a bit dry or dark for a flowering begonia.
Light Requirements
Indoors, "bright indirect light" is the golden rule. This means the plant should be in a spot where it can see the sky but is not hit by direct, scorching afternoon sun. A window facing east or west is often perfect. If you only have a south-facing window, place the plant a few feet back or use a sheer curtain to soften the light.
If the light is too low, the stems will become "leggy" or stretched out as the plant searches for the sun. If the light is too intense, the leaves may develop brown, crispy edges or a bleached appearance. During the shorter days of late fall, you may need to move your begonia to a brighter spot to keep it blooming.
Temperature and Airflow
Begonias are comfortable when you are comfortable. They thrive in temperatures between 65°F and 75°F. They are sensitive to sudden changes, so keep them away from cold drafts, air conditioning vents, or the direct blast of a space heater.
Good airflow is also helpful. In the still air of a house, fungal issues can sometimes develop if the foliage stays wet. Simply ensuring there is a little space between your plants is usually enough to keep the air moving naturally.
Managing Humidity
One of the biggest challenges with keeping begonias indoors is dry air, especially during the months when the heat is running. Begonias prefer a humidity level of around 50% to 60%. You can easily boost the moisture in the air around your plant without making the whole room feel damp.
A pebble tray is a simple and effective solution. Fill a shallow tray with small stones and add water until it is just below the tops of the pebbles. Set your begonia pot on top of the stones. As the water evaporates, it creates a small zone of higher humidity right where the plant needs it. Avoid misting the leaves directly, as standing water on begonia foliage can lead to mildew.
Key Takeaway: Success with indoor begonias starts with placement. Choose a bright spot with indirect light, keep temperatures steady, and use a pebble tray to maintain humidity.
Potting and Soil Selection
Because Non Stop begonias grow from tubers, they are very sensitive to how much water stays in the soil. The right pot and soil combination will make watering much easier to manage.
The Importance of Drainage
Drainage refers to how fast water leaves the soil and exits the pot. Begonias must never sit in soggy soil, which can cause the tuber to rot. Always choose a container with at least one drainage hole in the bottom. If you have a beautiful decorative "cachepot" that doesn't have holes, keep the begonia in a plain plastic nursery pot and set that inside the decorative one. This allows you to take the plant to the sink to water it and let it drain completely before putting it back.
The Best Potting Mix
Use a high-quality, soilless potting mix. These mixes are usually made of peat moss, coconut coir, and perlite. They are lightweight and designed to hold enough moisture for the roots while letting the excess drain away. Avoid using "garden soil" or "topsoil" from the backyard, as these are too heavy and may contain pests or diseases that can thrive in an indoor environment.
Pot Size and Repotting Strategy
Begonias actually prefer to be slightly root-bound. This means they like a pot that feels a little snug. When you are starting a new tuber or repotting a young plant, choose a container that is only an inch or two wider than the tuber itself. A 4-inch to 6-inch pot is a standard starting size for most Non Stop varieties.
For long-term indoor varieties like cane-stemmed begonia or Begonia rex, you should only repot when you see roots growing out of the drainage holes or if the plant needs watering much more frequently than usual. When repotting, move up only one pot size at a time to prevent the excess soil from holding too much moisture and causing root rot.
Watering and Feeding for Continuous Blooms
Proper watering is the most important skill for any begonia grower. Because the tuber stores water, the plant is more likely to be harmed by too much water than by a little bit of dryness.
The Finger Test
Instead of watering on a strict schedule, use the "finger test." Stick your finger into the soil up to the first knuckle. If the soil feels damp, wait a few days. If the top inch feels dry to the touch, it is time to water. When you do water, pour it onto the soil until it runs out of the drainage holes at the bottom. Empty any excess water from the saucer immediately.
Choosing the Right Fertilizer
To keep those "Non Stop" blooms coming, your plant needs regular nutrients. During the active growing season (spring through late summer), use a balanced liquid fertilizer. Look for a "bloom booster" formula with a higher middle number (phosphorus) to encourage flower production.
Dilute the fertilizer to half the strength recommended on the label. Apply it every two weeks. This "weakly, weekly" approach provides a steady stream of food without the risk of burning the sensitive roots. As the days get shorter in the fall and the plant begins to slow down, stop fertilizing altogether to let the plant prepare for its natural rest.
What to Do Next: Daily Care and Grooming
- Check the soil daily with your finger to see if it needs water.
- Rotate the pot a quarter-turn every week so the plant grows evenly toward the light.
- Pinch and Prune: To keep your begonias from becoming leggy, pinch off the growing tips of young stems. This encourages the plant to branch out and become bushier. For upright cane types, don't be afraid to cut back tall stems by a third to maintain a compact shape.
- Pinch off faded flowers (deadheading) to encourage the plant to produce new buds.
- Remove yellowing leaves to keep the plant looking tidy and prevent mold.
Bringing Outdoor Begonias Inside
If you have been enjoying Non Stop begonias in your garden or on your patio, you can bring them indoors to extend their life or to save the tubers for next year. The key is to do this before the weather gets too cold. If you want more winter-transition guidance, see our Can Begonia Plants Be Brought Indoors? Expert Winter Tips.
Timing the Move
Ideally, move your begonias inside before the first frost. While a light frost might only kill the leaves, a hard freeze can damage the tuber itself. Transitioning the plant while the outdoor temperatures are still somewhat close to your indoor temperatures will reduce the shock to the plant.
The Cleanup Process
Before bringing any plant into your home, give it a thorough inspection. Check the undersides of the leaves and the stems for any hitchhiking insects. It is a good idea to give the plant a gentle spray with a garden hose to wash away dust and any small pests. Trim off any damaged or straggling stems to make the plant more manageable.
Expect Some Leaf Drop
When you move a begonia from the high-light environment of the outdoors to the lower-light environment of a house, it will need to adjust. It is very common for the plant to drop a few leaves or for some existing flowers to wilt. Don't worry—this is a natural reaction. Once the plant acclimates to its new spot, it will often begin to produce new leaves that are better suited to indoor light levels.
The Art of the Winter Rest
One of the most common questions we hear is whether a Non Stop begonia can stay green and blooming all winter indoors. While you can keep them going longer than they would survive outside, they ultimately require a period of dormancy.
Why Dormancy Matters
A begonia tuber is like a battery. Throughout the summer, the leaves collect sunlight and turn it into energy, which is stored in the tuber. By the end of the year, that energy is used up, and the tuber needs a "recharge" period of rest. If you force the plant to keep growing through the winter without a break, it will become weak, spindly, and may eventually fail to bloom or die.
Recognizing the Signs
In late fall or early winter, you will notice the plant's growth slowing down. The flowers will become fewer, and the leaves may start to yellow even if you are watering correctly. This is the plant's way of saying it is ready for its winter nap. This is not a failure; it is a healthy part of the plant's life cycle.
Key Takeaway: Non Stop begonias are seasonal plants. Recognizing the signs of dormancy allows you to help the plant rest so it can return with even more vigor the following year.
Storing Begonia Tubers Indoors
When the plant begins to decline in late fall, it is time to transition it into storage. This is a very simple process that allows you to save your favorite varieties year after year.
Step 1: Withhold Water
Stop watering the plant. Allow the soil to dry out completely. As the soil dries, the plant will draw the remaining moisture and nutrients from the stems down into the tuber. The stems will eventually become soft and may even fall off on their own.
Step 2: Clean the Tubers
Once the foliage has withered and the soil is dry, gently lift the tubers out of the pot. Brush off the excess soil with your hands. Do not wash them with water, as you want them to stay dry during storage. Carefully pull off any remaining bits of stem or dried roots. If the stem doesn't come away easily, wait a few more days until it is completely dried out.
Step 3: Cure the Tubers
Place the cleaned tubers on a newspaper in a dry, room-temperature spot for about a week. This "curing" process allows the outer skin of the tuber to toughen up slightly, which helps prevent rot during the winter.
Step 4: The Storage Container
Store the tubers in a breathable material. A paper bag, a cardboard box, or a plastic container with holes works well. Fill the container with dry peat moss, perlite, or vermiculite and nestle the tubers inside so they aren't touching each other. This prevents any potential rot from spreading.
Step 5: The Right Location
The best place to store begonia tubers is a cool, dark, and dry spot. A temperature between 40°F and 50°F is ideal. An unheated basement, a cool closet, or an insulated garage (that doesn't freeze) are usually the best options. Check them once a month to make sure they aren't getting soft or shriveled. If they look very shriveled, you can give the storage medium a very light mist of water, but keep it minimal.
Waking Them Up: The Spring Restart
One of the most exciting parts of gardening is seeing those first green nubs emerge from a dormant tuber. In late February or early March, you can begin the process of "waking up" your begonias indoors.
Identifying the Top
Take your tubers out of storage and look for the "eye" or the growing point. Begonia tubers are usually shaped like a thick disc with one side that is slightly hollow or indented. This hollow side is the top. The rounded, smooth side is the bottom where the roots will grow.
Starting the Tubers
Place the tubers in a shallow tray filled with damp potting mix. Do not bury them deeply; the top of the tuber should be just level with or slightly above the soil surface. Place the tray in a warm, bright spot (about 70°F).
Water very sparingly at first. You want the soil to be barely moist. If the soil is too wet before the roots have formed, the tuber can rot. Within a few weeks, you should see small pink or green sprouts emerging from the hollow center.
Moving to Permanent Pots
Once the sprouts are about an inch tall and you see small leaves forming, you can move each tuber into its own pot. Use the same high-quality soilless mix we discussed earlier. As the stems grow, you can gradually increase the amount of light and water the plant receives. By the time the weather warms up outside, you will have a healthy, established plant ready to go back out or to stay on your sunny windowsill.

Propagation Methods by Type
If you have a particularly beautiful begonia and want more of them, you can easily grow new plants through various propagation methods depending on the type you have.
Stem Cuttings for Non Stop and Cane Begonias
This is a fun project to do in the late spring or early summer when the plant is growing vigorously.
- Take the cutting: Choose a healthy stem that is about 3 to 4 inches long. Use a clean, sharp pair of scissors to cut just below a "node" (the bump where a leaf attaches to the stem).
- Prepare the stem: Remove the lower leaves, leaving only two or three at the very top. If there are any flower buds, pinch them off.
- Rooting: You can place the cutting in a small glass of water or stick it directly into a small pot of moist vermiculite or perlite.
- Maintain humidity: If using soil, cover the pot with a clear plastic bag to keep the humidity high. Place it in bright, indirect light.
- Wait for roots: In two to four weeks, the cutting should develop roots. Once they are an inch long, plant it in regular potting soil.
Leaf Cuttings for Rex and Rhizomatous Types
For Begonia rex or rhizomatous begonia types, you can actually grow a whole new plant from a single leaf. You can either pin a leaf flat onto moist soil after making small nicks in the veins, or cut the leaf into wedges that each contain a main vein and stand them upright in a rooting medium. Keep them warm and humid, and tiny plantlets will eventually form at the base.
Dividing Rhizomes
For older rhizomatous plants that have become crowded, you can simply divide the thick, creeping stems (rhizomes) into sections. Ensure each section has at least one growing point and some roots, then pot them up individually.
Troubleshooting Common Indoor Issues
Gardening is a learning process, and even experienced growers run into minor hurdles. Most indoor begonia issues can be solved by adjusting one simple factor at a time.
Indoor Pests to Watch For
While begonias are relatively hardy, the still, warm air of a home can sometimes attract pests.
- Mealybugs: These look like small bits of white cotton hiding in the leaf axils or under leaves. Wipe them off with a cotton swab dipped in rubbing alcohol.
- Whiteflies: Small, moth-like insects that flutter when the plant is disturbed. They can be managed with insecticidal soap or yellow sticky traps.
- Spider Mites: These tiny pests thrive in dry air and create fine webbing on the plant. Increasing humidity and washing the leaves can help prevent them.
Leggy Stems
If your begonia is growing very tall with long spaces between the leaves, it is telling you it needs more light. Move it closer to a window or add a small LED grow light. You can also pinch back the tips of the stems to encourage the plant to grow bushier.
Dropping Buds
If the plant produces flower buds but they fall off before opening, it is often a sign of stress. This can be caused by a sudden temperature change (like a cold draft) or by the soil getting too dry. Check your watering routine and make sure the plant is in a stable environment.
Powdery Mildew and Rot
Powdery mildew looks like a dusting of white flour on the leaves. It usually happens when the air is too still or the leaves are getting wet. Improve airflow and water only the soil. If the base of the stems or the tuber becomes soft and mushy, this is rot from excess moisture. Stop watering immediately and ensure the pot has better drainage.
Yellow Leaves
A few yellow leaves at the base of the plant are normal as it grows. However, if many leaves are turning yellow, it is usually a sign of overwatering. Let the soil dry out more between waterings and make sure the pot is draining well.
Conclusion
Non Stop begonias are some of the most rewarding plants you can grow, offering a spectacular display of color that truly lives up to its name. While they have a specific seasonal cycle, they are remarkably adaptable to life indoors if you provide them with bright light, consistent moisture, and a little extra humidity. Whether you are using them to decorate a sunroom or simply overwintering them to save for next year, these plants bring a touch of tropical elegance to any home.

FAQ
Are Non Stop begonias toxic to pets?
Yes, begonias are known to be mildly toxic to cats and dogs if eaten. The most toxic part of the plant is the tuber itself, which is hidden underground. To be safe, it is best to keep your indoor begonias on high shelves or in areas where your pets cannot reach them.
Can I grow Non Stop begonias from seed indoors?
While it is possible, growing tuberous begonias from seed is a very slow process that requires specific light and temperature controls for several months. For most home gardeners, starting with dormant tubers or established plants is much easier and provides much faster results for the summer blooming season.
Why did my begonia stop blooming while indoors?
The most common reasons for a lack of blooms are insufficient light or a lack of fertilizer. Begonias need plenty of energy to produce those large, double flowers. Ensure the plant is in a bright location and that you are using a phosphorus-rich fertilizer every two weeks during the growing season.
How many years will a begonia tuber last?
With proper care and a consistent winter dormancy period, a begonia tuber can last for many years. As the tuber gets older, it will often grow larger and produce a more substantial plant with even more flowers. Some gardeners have kept favorite tubers for a decade or more!
Which begonia types are easiest to keep indoors long-term?
Cane-stemmed varieties, such as the angel wing begonia, and many rhizomatous begonia types are the most reliable for year-round indoor growth because they do not require a dormant period like tuberous varieties do.
What should I do if my indoor begonia looks leggy?
Leggy growth is usually a sign of low light. Move the plant to a brighter location and pinch back the growing tips of the stems. This removes the "apical dominance" and forces the plant to activate side buds, resulting in a fuller, more attractive plant.
