Begonias are some of the most popular flowering plants grown in gardens and containers. With their showy abundant blooms in colors ranging from red and pink to white and yellow, it’s easy to see why begonias are garden favorites. As a begonia owner, you may be wondering do I need to deadhead my begonias?
The simple answer is: no, deadheading is not essential for most begonia varieties. However, regularly removing spent flowers can encourage more blooms, improve plant health, and enhance the overall appearance of your begonias.
What Is Deadheading?
Deadheading refers to pinching or cutting off faded, wilted, or dried flowers from plants. It redirects the plant’s energy from seed production to generating new buds and blooms instead.
Deadheading makes plants look tidier by getting rid of unsightly dying flowers. It also extends the flowering period by promoting continuous reblooming.
Do All Begonias Require Deadheading?
Most begonias do not need deadheading to bloom freely. The main exception is begonia x tuberhybrida, or tuberous begonias. Tuberous begonias tend to flower longer when old blossoms are regularly removed
Other popular begonia varieties like wax begonias, dragon wing begonias, rhizomatous begonias, and rex begonias will bloom abundantly without deadheading. Here’s a quick overview:
- Tuberous begonias – Benefit from deadheading
- Wax begonias – Usually don’t require deadheading
- Dragon wing begonias – Don’t need deadheading
- Rex begonias – Don’t need deadheading
- Rhizomatous begonias – Deadheading not necessary
- Semperflorens begonias – Don’t require deadheading
- Trailing/cascade begonias – Deadheading not needed
So for most begonias, deadheading is optional. But it can prolong blooming, especially for tuberous begonias. Removing spent flowers improves appearance and plant health.
When to Deadhead Begonias
The ideal time to deadhead tuberous begonias is once a week during their active blooming period. For other begonias, deadhead whenever you notice faded or browning flowers.
Here are some deadheading guidelines based on the type of begonia:
-
Fibrous begonias – Deadhead every 1-2 weeks or as needed during the growing season.
-
Tuberous begonias – Deadhead weekly during the bloom period from late spring to early fall
-
Rex begonias – Deadhead anytime flowers become unsightly. Blooms are less prolific.
-
Wax begonias – Deadhead frequently, even daily if possible. Quick rebloomers.
-
Rhizomatous begonias – Deadhead as blooms fade. Flowering is intermittent.
Deadheading early, before seed pods form, ensures the plant focuses energy on new buds rather than seeds. But allow some blooms to remain later in the season for collecting seeds.
How to Deadhead Begonias
Deadheading begonias is a simple, quick task. Follow these steps:
-
Use clean, sterilized pruning shears or scissors to remove spent blooms. Make cuts just above a leaf node.
-
Alternatively, you can pinch off flowers by hand for smaller, more delicate begonias.
-
Clip the entire flower stem back to a healthy leaf, removing the faded bloom and any seed pod present.
-
Check plants frequently and deadhead often to encourage reblooming.
-
Remove all dead bloom debris from around plants to prevent disease issues.
-
Consider selectively pruning back leggy or overgrown stems by 1/3 to promote bushy regrowth.
-
Stake tall varieties before deadheading to prevent toppling.
Take care not to over-prune when deadheading begonias. Conservative, selective removal of spent blooms is best. With proper deadheading, your begonias will continue blooming vigorously all season.
Benefits of Deadheading Begonias
Here are some of the top benefits of regularly removing spent begonia flowers:
-
Encourages more blooms – Deadheading tells the plant to generate more flower buds instead of seeds. This extends the flowering period.
-
Improves appearance – Getting rid of faded, unsightly blooms keeps begonias looking fresh and tidy. Great for containers and garden beds.
-
Prevents disease – Removing old blooms minimizes the risk of fungal diseases like botrytis.
-
Promotes bushy growth – Deadheading encourages more branching and full, compact growth habit.
-
Maximizes plant energy – With no seed production, energy is focused on generating new buds and foliage.
-
Easy maintenance – Only takes minutes to deadhead begonias as needed. Promotes plant health and flowering.
For the most prolific floral display, get into the habit of regularly deadheading your begonias’ spent blooms.
Caring for Begonias After Deadheading
After deadheading, follow these tips to keep your begonias thriving:
-
Water thoroughly after deadheading. Begonias prefer consistently moist soil.
-
Apply a diluted balanced fertilizer every 2-4 weeks during the growing season.
-
Monitor for pests like aphids or mealybugs and treat any issues promptly.
-
Prune back overgrown stems and shape plants by selectively removing extra growth.
-
Provide filtered sunlight, humidity, and temperatures between 65°F to 75°F for optimal growth.
-
Bring potted begonias indoors before frost or dig up tubers for winter storage once blooming ends.
With proper deadheading and care, your begonias will continue blooming from spring through fall, lighting up your garden or containers with their vibrant colored blossoms.
Do You Have to Deadhead Begonias?
While deadheading isn’t essential for most begonias, doing so regularly offers many benefits. Removing spent blooms improves the plant’s appearance, encourages prolific reblooming, prevents disease, and promotes bushy, compact growth.
Prioritize deadheading for heavy bloomers like tuberous, wax, and dragon wing begonias. For rhizomatous and rex begonias, deadhead whenever blooms become unsightly. Take care not to over-prune when deadheading.
Coupled with proper care, regularly removing spent flowers will keep your begonias flowering nonstop and looking their best all season long. So consider making deadheading a part of your begonia care routine.
How to Prune Begonias
Step 1 – Inspect the Begonia
Look for stems that have become leggy or are in areas that you would like to be bushier.
Step 2 -Begin Pruning
Use your thumb and finger to pinch off the growing tips on begonias stems. The stems easily break making pruners unnecessary.
Step 3 – Deadhead
Remove all dead and faded flowers daily or as needed.
When to Prune Begonias
Cut back the growing tips on begonias branches every 2 to 4 weeks or if your plants become leggy. The plant will produce new branches from the pinched point. Additional stems provide more opportunities for the begonia to create flowers.
Tuberous begonias die back every year. The tubers can be dug up and stored for replanting the following year. Begonias that grow from rhizomes retain their foliage all year long and can be moved indoors as houseplants during the colder months.
Deadhead regularly to keep your plant looking neat and to prevent the chance of rotting flowers from attracting disease.
