Dahlia 'Bishop of Leicester' (Misc)

Water

Dahlias, including the 'Bishop of Leicester', prefer consistently moist but not waterlogged soil. During the growing season, water dahlias deeply a couple of times a week, providing about 1 to 2 gallons per plant for each watering, depending on weather conditions. Reduce watering frequency if rain provides sufficient moisture. It's essential to avoid overhead watering to prevent foliage diseases; instead, use a soaker hose or drip irrigation at the base of the plant. In hot, dry periods, you may need to water more frequently, ensuring the soil remains moist to a depth of several inches. As the plant prepares for dormancy after blooming ends, gradually decrease the amount of water.

Light

Dahlias, such as the 'Bishop of Leicester', thrive in full sun, meaning they should receive at least 6 to 8 hours of direct sunlight each day for optimal growth. The ideal location offers morning sunlight and some protection from the intense afternoon sun, especially in hotter climates. Avoid planting in areas that are shaded, as insufficient light can lead to weak growth and fewer blooms.

Temperature

The 'Bishop of Leicester' dahlia prefers a temperature range of around 60 to 75 degrees Fahrenheit during the day and 55 to 65 degrees Fahrenheit at night. Extreme temperatures below 50 degrees or above 90 degrees Fahrenheit can stress the plant. Dahlias are not frost-tolerant and should be planted after all danger of frost has passed in the spring.

Pruning

Pruning the 'Bishop of Leicester' dahlia helps to encourage a bushier plant with more blooms. Pinch out the growing tips once the plant reaches about 15 inches tall to promote branching. Deadhead spent flowers regularly to stimulate continuous blooming throughout the season. The best time for significant pruning is early spring, as new growth begins, or during the growing season for maintenance.

Cleaning

As needed

Soil

The best soil mix for dahlias like 'Bishop of Leicester' consists of fertile, well-draining soil with incorporated organic matter such as compost or peat moss. A slightly acidic to neutral pH, ranging from 6.5 to 7.0, is ideal to promote healthy growth and vibrant blooms.

Repotting

Dahlias, like the 'Bishop of Leicester', generally do not require frequent repotting and are often replanted yearly. The tubers can be lifted after the first frost in autumn, stored during the winter, and replanted in the spring.

Humidity & Misting

Dahlias like 'Bishop of Leicester' prefer moderate humidity levels. Consistent ambient humidity without being overly damp or dry is suitable, as excessive moisture can encourage fungal diseases.

Suitable locations

• Indoor

  Place in bright, indirect light and ensure good air circulation.

• Outdoor

  Full sun, protect from winds and stake as the plant grows.

• Hardiness zone

  8-11 USDA

Life cycle

The life cycle of the Dahlia 'Bishop of Leicester' begins with the sprouting of tubers in spring after the last frost when the soil has warmed. The plant then develops a sturdy stem and a lush foliage, which are followed by the flowering period in summer and early fall where it produces its distinctive purplish-pink flowers. As a perennial, it reaches maturity and a full display of blooms in its first year, provided optimal growing conditions. As temperatures drop in late fall, the plant begins to die back and enters dormancy; the tubers can be lifted and stored in a cool, frost-free place. The stored tubers are replanted the following spring to start a new growth cycle. Throughout its life cycle, careful maintenance including proper watering, staking, and deadheading of spent flowers encourages robust health and abundant blooms.

Propogation

• Propogation time

  Late Winter - Early Spring

• The Dahlia 'Bishop of Leicester', a variety of the common dahlia, is typically propagated through the division of tubers. The best time to do this is in the spring when the soil has warmed up and there is no risk of frost. During this process, the tubers that have been overwintered are taken out of storage and carefully divided to ensure that each new section has at least one eye, which is a growth point. The cuts should be made with a sharp, clean knife to minimize damage and reduce the risk of disease. Once divided, the tubers can be planted directly into the garden at a depth of about 6 inches (15 centimeters) with the eye facing upwards. It's important to water the newly planted tubers generously to encourage growth. This method is favored for its simplicity and effectiveness in increasing the number of plants while maintaining the genetic characteristics of the dahlia variety.
