Begonia Growing Guide for Zone 9

Planting Time: In Florida, plant begonias in early spring or fall. Begonias thrive in warm, humid weather and can tolerate the heat of summer, making them suitable for both spring and fall planting.

Soil: Begonias prefer well-draining, slightly acidic soil with a pH between 5.5 and 6.5. Adding compost or well-rotted manure to the soil can improve fertility and structure.

Sun: Begonias grow best in partial shade to full shade, requiring at least 4-6 hours of indirect sunlight daily. Too much direct sunlight can scorch the leaves.

Watering: Keep the soil consistently moist but not waterlogged. Water regularly, especially during dry spells, to keep the soil evenly moist. Avoid getting water on the leaves to prevent fungal diseases.

Spacing: Plant begonia seeds or transplants 8-12 inches apart. Proper spacing ensures adequate air circulation and room for growth.

Fertilization:
N-P-K Ratio: Begonias benefit from a balanced fertilizer with a slightly higher phosphorus content to support strong root and flower development, such as 10-10-10 or 5-10-5.

When to Add:

• Before Planting: Apply the fertilizer to the soil before planting seeds or transplants to promote strong initial growth.

• Early Spring: Reapply the fertilizer in early spring as new growth begins.

Application Tips:

• Follow the directions on the fertilizer package to avoid over-fertilization.

• Apply the fertilizer evenly around the base of the plants and water thoroughly to help the nutrients reach the roots.

Additional Tips:

• Begonias grow best in well-drained soil rich in organic matter, so consider adding compost to improve soil fertility and structure.

• Mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

• Ensure that begonias receive consistent moisture, especially during flowering, to prevent stress and promote abundant blooming.
