Dahlia Dahlia 'Trelyn Daisy' (Col)

Water

Dahlia 'Trelyn Daisy' requires consistent moisture, so you should water them to keep the soil slightly damp but never soggy. Typically, you should water these dahlias with about 1 to 2 inches of water per week, adjusting for rainfall. During the active growing season, especially in the absence of rain, you might find the need to water them 2 to 3 times per week. It's essential to use a gentle watering method, like a drip line or a hose with a diffuser nozzle, to avoid displacing soil or damaging the flowers and foliage. Ensure that the water reaches deep into the soil to encourage deep root growth.

Light

Dahlias prefer full sun conditions, so place your Dahlia 'Trelyn Daisy' in a spot where it will receive at least 6 to 8 hours of sunlight each day. They thrive in areas with morning sunlight and some partial shade during the hottest part of the afternoon, if possible. Avoid placing them in full shade as it can lead to poor bloom production and weak, elongated growth.

Temperature

For the Dahlia 'Trelyn Daisy', the ideal growing temperatures are between 60 and 75 degrees Fahrenheit. They can tolerate a minimum temperature no lower than 50 degrees Fahrenheit and a maximum temperature of around 90 degrees Fahrenheit. However, prolonged exposure to temperatures outside of the 60-to-75-degree range can stress the plant and affect its blooming and growth.

Pruning

Pruning Dahlias such as 'Trelyn Daisy' encourages better blooms and a more vigorous plant. Deadheading, or pruning off spent flowers, should be done regularly, as often as every three days during the peak blooming season, to maintain plant aesthetic and encourage more blooms. Additionally, cutting back the plant in midsummer, by removing about a third of the plant, can lead to a bushier plant with more flowers. The best time to prune is in the morning when the plant is well-hydrated.

Soil

Dahlias like 'Trelyn Daisy' thrive best in a well-draining soil mix with a slightly acidic to neutral pH of 6.5 to 7.0. A mix of two parts garden soil to one part peat or coco coir and one part perlite or sand provides aeration and proper drainage. It's important to ensure the soil is nutrient-rich, so incorporating compost or well-rotted manure can enhance plant health and bloom quality. Regular soil testing and amendment can help maintain optimal conditions for these vibrant flowers.

Repotting

Dahlias such as 'Trelyn Daisy' generally need to be repotted every year if they are grown in containers. These tuberous plants require fresh soil to provide the nutrients necessary for healthy growth and bloom production. The best time to repot is in the early spring as new growth begins. Always choose a pot only slightly larger than the previous one to prevent the soil from remaining too wet and causing rot.

Humidity & Misting

Dahlias, including 'Trelyn Daisy', prefer moderate humidity levels. While they can adapt to various conditions, maintaining humidity around 40-60% is generally best to prevent issues such as powdery mildew. They do not require the high humidity levels that some tropical plants might, making them suitable for many temperate garden environments.

Suitable locations

• Indoor

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

• Outdoor

  Plant 'Trelyn Daisy' in full sun, ensure well-draining soil and spacing.

• Hardiness zone

  8-11 USDA

Life cycle

The life cycle of the Dahlia 'Trelyn Daisy' begins with seed germination, where under the correct conditions of warmth and moisture, the plant's seeds sprout roots and shoots. Following germination, the seedling stage is marked by the emergence of the primary leaves as the plant establishes itself. The vegetative stage then sees rapid growth as the dahlia develops its characteristic foliage and robust stem structure in preparation for blooming. Flowering occurs during the reproductive stage, where the 'Trelyn Daisy' dahlias produce their showy, colorful blooms that are often sought after for ornamental purposes. After pollination, if it occurs, seeds develop which concludes the reproductive phase. Finally, the post-blooming phase for dahlias often involves a period of senescence or dormancy, especially in colder climates, where the tubers can be overwintered for planting in the next season to complete the cycle.

Propogation

• Propogation time

  Spring-Early Summer

• The Dahlia 'Trelyn Daisy', commonly known as just Dahlia, is best propagated through division, which is typically done in the spring when new shoots begin to emerge from the tubers. To propagate by division, carefully dig up the tuber clump after the foliage has died back post-frost in the fall or just before growth restarts in the spring. Gently separate the tubers, ensuring each section has at least one eye or bud from which new growth can sprout. Cuttings can also be taken in spring from the new shoots, but division remains the most popular because it is straightforward and helps to rejuvenate clumps that have become too dense. It's important to let the cut surfaces of the divided tubers dry for a day or two to form a protective callus before planting them back into the soil. The divided tubers should be planted about 4 to 6 inches (10 to 15 centimeters) deep, with the eye or bud facing upwards, and spaced about 18 to 24 inches (45 to 60 centimeters) apart to give each new plant ample room to grow.
