What Are Tuberous Begonias?
So, what exactly are tuberous begonias? These plants grow from tubers—think of them as little storage units packed with energy. Unlike other begonias, tuberous begonias are famous for their big, bold flowers that come in colors like red, pink, yellow, and white. They bloom from summer to fall, making them a go-to for long-lasting color.
I first fell in love with them when I saw a neighbor’s hanging basket overflowing with tuberous begonia flowers—it was like a living fireworks display! They’re super versatile too. You can grow them in pots, baskets, or right in the ground. Want to explore more begonia options? Check out my article on different begonia varieties over at USA Garden Hub.
Planting Tuberous Begonias
Planting tuberous begonias is pretty straightforward, but a little know-how goes a long way. Here’s how I do it.
Choosing the Right Tubers
Start with healthy begonia tubers. Look for ones that are firm, not mushy or moldy. I’ve had great luck ordering tuberous begonia tubers for sale from places like White Flower Farm or Longfield Gardens. Quality tubers make all the difference!
When and Where to Plant
Tuberous begonias love partial shade—think morning sun, afternoon shade. In the USA, late spring is prime planting time, after the last frost. Not sure about frost dates in your area? The Old Farmer’s Almanac has you covered.
Step-by-Step Planting Guide
- Start Indoors: About 8-12 weeks before the last frost, I plant my begonia tubers indoors. Pop them in pots, hollow side up, and cover with an inch of potting soil.
- Water Sparingly: Keep the soil just moist—too much water can rot the tubers. I learned that the hard way my first year!
- Transplant Outdoors: Once frost is gone, move them outside. Space them 12-18 inches apart so they’ve got room to shine.

Tuberous Begonia Care
Caring for tuberous begonias isn’t rocket science, but they do have preferences. Here’s what works for me.
Watering and Feeding
- Watering: I water when the top inch of soil feels dry. They like consistent moisture but hate soggy feet. A drip irrigation system has been a game-changer for me.
- Feeding: Every 4-6 weeks, I give them a balanced, water-soluble fertilizer. It’s like a little boost to keep those blooms popping.
Light and Temperature Needs
Tuberous begonias thrive in 60-75°F weather and bright, indirect light. Too much sun burns their leaves—trust me, I’ve scorched a few! They’re not fans of frost either, so I bring them in when it gets chilly.
Common Pests and Problems
Pests can sneak up on you. Here’s what to watch for:
- Aphids: Tiny bugs I blast with insecticidal soap.
- Powdery Mildew: A fuzzy white coating. Good airflow and no overhead watering keep it at bay.

How to Deadhead Tuberous Begonias
Deadheading tuberous begonias is my secret to nonstop blooms. It’s easy—pinch off the faded flowers every few days. I’ll stroll through my garden with a cup of coffee, snipping away. It keeps the plant neat and pushes it to make more flowers. New to this? The University of Minnesota Extension has a handy deadheading guide.
Overwintering Tuberous Begonias
Here’s a cool perk: you can save tuberous begonia tubers for next year! After 10 years of gardening, I’ve got this down pat:
- Dig Up the Tubers: Post-first frost, I gently dig them up and shake off the soil.
- Dry and Store: Let them dry out for a few days, then tuck them into a box with peat moss or vermiculite.
- Check In: Every few weeks, I peek for mold or rot and toss anything funky.
In spring, they’re ready to replant. Want more details? Michigan State University’s overwintering guide is a gem.
