PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The best time to plant Dahlia ‘Bishop of York’ is in spring, when the soil has warmed. Planting at this time gives the tubers ample time to establish themselves before blooming.
• Autumn: Alternatively, you can plant in early autumn to allow the plant to settle in before dormancy, setting the stage for strong growth the following spring.

Site Selection

• Sunlight: Dahlia ‘Bishop of York’ requires full sun to thrive. Choose a location that receives at least 6 hours of direct sunlight daily. This ensures optimal flower production and healthy growth.
• Soil: Well-drained soil is crucial for Dahlias. Avoid waterlogged conditions, as they can cause root rot. To improve soil fertility and drainage, incorporate compost or other organic matter.

Planting Instructions

1. Prepare the Hole: Dig a hole that is twice the width and depth of the Dahlia tuber. This will allow the roots to spread freely.
2. Soil Preparation: Mix compost or well-rotted organic matter into the soil. This will enhance fertility and ensure good drainage, helping your Dahlia ‘Bishop of York’ grow vigorously.
3. Planting: Place the tuber in the hole, ensuring that the top of the root ball is level with the surrounding soil. Gently backfill the hole and firm the soil to remove any air pockets.
4. Watering After Planting: Water thoroughly after planting to settle the soil and encourage root establishment. Ensure that the area drains well to prevent waterlogging.

Watering Requirements

• Growing Season: Once established, Dahlia requires moderate watering. During dry spells, water deeply, allowing the soil to dry slightly between waterings. Avoid overwatering to prevent root rot.
• Dormant Season: Reduce watering significantly during the dormant season. Only water if the soil becomes excessively dry, as Dahlia ‘Bishop of York’ needs minimal moisture during this time.

Feeding

• Spring: Apply a balanced fertiliser in early spring to encourage strong growth and vibrant flowers. This helps Dahlia ‘Bishop of York’ get off to a healthy start in the growing season.
• Mid-Summer: A light feeding in mid-summer can boost flower production and keep your Dahlia blooming consistently throughout the season.

Pruning

• Deadheading: Regularly deadhead your Dahlia to encourage continued flowering. Removing spent blooms helps keep the plant looking tidy and promotes new flower production.
• Autumn Pruning: Once the last flowers fade in autumn, cut back the plant to ground level. This will prepare the Dahlia for winter dormancy and promote stronger growth the following spring.

Mulching

• Spring: Apply a layer of mulch around the base of your Dahlia ‘Bishop of York’ in spring to retain moisture, suppress weeds, and regulate soil temperature. Organic materials like bark chips or compost work best.
• Winter: In winter, mulch around the plant to protect the tubers from frost. This layer will help ensure your Dahlia survives until the next growing season.

Supporting the Plant

• Staking: Although Dahlia ‘Bishop of York’ has sturdy stems, it may benefit from staking if you live in an area with strong winds. Staking provides additional support, helping the plant maintain an upright growth habit and preventing damage.

Final Tips

By following these planting and care tips, your Dahlia ‘Bishop of York’ will thrive in full sun, well-drained soil, and produce stunning flowers that brighten your garden.
