Understanding Begonia Bulbs
Before diving into the planting process, let’s first understand the different types of begonia bulbs. While the term “bulb” is commonly used, begonias actually propagate through tubers and rhizomes.
- Tuberous Begonias: These are the most popular type, known for their large, showy flowers. They have thick, rounded tubers that resemble small potatoes.
- Rex Begonias: These are prized for their striking foliage, featuring a variety of colors, patterns, and textures. They propagate through rhizomes, which are horizontal stems that grow along the soil surface.
When to Plant Begonia Bulbs: A Regional Guide
The ideal time to plant begonia bulbs varies depending on your location and climate. Here’s a general guide:
Warm Climates (USDA Zones 9-11):
- Tuberous Begonias: Plant in late winter or early spring, after the last frost.
- Rex Begonias: Plant in spring or early summer, after the soil has warmed up.
Moderate Climates (USDA Zones 5-8):
- Tuberous Begonias: Plant in late spring or early summer, after the soil has warmed up and the risk of frost has passed. You can also start them indoors in early spring.
- Rex Begonias: Plant in spring or early summer, after the soil has warmed up.
Cold Climates (USDA Zones 3-4):
- Tuberous Begonias: Plant in late spring or early summer, after the last frost. It’s best to start them indoors and transplant them outdoors after the soil has warmed up.
- Rex Begonias: These are not typically grown in cold climates due to their sensitivity to frost.
Preparing the Soil for Begonia Bulbs
Begonia bulbs thrive in well-drained, fertile soil. Here’s how to prepare your planting area:
1. Choose a sunny location: Tuberous begonias prefer at least 6 hours of sunlight per day, while Rex begonias tolerate partial shade.
2. Amend the soil: Mix in compost or well-rotted manure to improve drainage and add nutrients.
3. Test the soil pH: Begonias prefer slightly acidic soil with a pH of 5.5 to 6.5. You can adjust the pH with lime or sulfur if needed.
4. Remove weeds: Clear the area of any weeds that could compete with your begonia bulbs.
Planting Begonia Bulbs: A Step-by-Step Guide
1. Choose healthy bulbs: Look for plump, firm bulbs with no signs of rot or damage.
2. Soak the bulbs: Soak the bulbs in water for a few hours to rehydrate them.
3. Plant the bulbs: Plant tuberous begonia bulbs with the “eye” facing up, about 1-2 inches deep and 12-18 inches apart. Plant Rex begonia rhizomes horizontally, just below the soil surface.
4. Water thoroughly: Water the bulbs well after planting.
5. Mulch: Apply a layer of mulch around the bulbs to help retain moisture and suppress weeds.
Caring for Begonia Bulbs
Once you’ve planted your begonia bulbs, there are a few essential care tips to follow:
- Water regularly: Keep the soil consistently moist but not soggy.
- Fertilize: Feed your begonias with a balanced fertilizer every few weeks during the growing season.
- Deadhead spent flowers: This will encourage more blooms.
- Protect from frost: In colder climates, bring your begonias indoors or cover them with frost blankets during the winter months.
Bringing Your Begonia Bulbs Indoors
If you live in a cold climate, you’ll need to bring your begonia bulbs indoors for the winter. Here’s how to do it:
1. Dig up the bulbs: Once the foliage has died back, carefully dig up the bulbs.
2. Clean the bulbs: Brush off any excess soil and remove any dead leaves.
3. Store the bulbs: Store the bulbs in a cool, dry, and dark place, such as a basement or garage.
4. Replant in spring: Replant the bulbs outdoors when the soil has warmed up in the spring.
