Growing Dahlia 'Bishop of Auckland' can be rewarding, as this variety produces stunning, deep purple flowers. Here’s how to cultivate them successfully:
1. Choosing the Right Location
- Sunlight: Select a spot that receives full sun (at least 6-8 hours per day).
- Soil: Well-draining soil is essential. Amend with organic matter if necessary.
2. Planting Time
- When: Plant tubers in spring, after the last frost date.
- How: Dig a hole about 4-6 inches deep, place the tuber with the eye facing up, and cover lightly with soil.
3. Watering
- Initial Watering: Water immediately after planting.
- Ongoing Care: Keep the soil consistently moist but not waterlogged. Water deeply once a week.
4. Fertilizing
- Use a balanced fertilizer (like 10-10-10) when planting and again mid-season.
- Avoid high-nitrogen fertilizers, as they can promote foliage over blooms.
5. Staking
- As the plants grow, stake them to support the tall stems and prevent breakage.
6. Deadheading
- Remove spent flowers to encourage more blooms and prolong flowering.
7. Pest and Disease Management
- Watch for aphids, slugs, and powdery mildew. Use organic pesticides or fungicides as needed.
8. Winter Care
- In colder climates, dig up the tubers after the first frost, let them dry, and store in a cool, dry place until spring.
9. Propagation
- Divide tubers every few years to maintain vigour and increase plant numbers.
Tips
- Mulching can help retain moisture and suppress weeds.
- Regularly check for pests and diseases to keep plants healthy.
With these care tips, your Dahlia 'Bishop of Auckland' should thrive and produce beautiful blooms throughout the growing season!
