Dahlia Dahlia 'Trelyn Crimson' (Col)

Water

Dahlias require consistent moisture, so water your Dahlia 'Trelyn Crimson' thoroughly whenever the top inch of soil feels dry to the touch. Typically, this means watering once or twice a week, but the frequency may increase during particularly hot or windy periods. Apply water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. During the growing season, a dahlia may need about 1 to 2 gallons of water each week, depending on weather conditions. Always adjust watering based on rainfall, as overwatering can be as detrimental as underwatering.

Light

Dahlias thrive in full sun, so the Dahlia 'Trelyn Crimson' should be placed in a spot where it gets at least 6 to 8 hours of sunlight daily. Avoid shaded areas as insufficient light can lead to poor bloom development. The best spot for your dahlia is in an area with bright, direct light but protected from intense midday sun in regions with very hot climates.

Temperature

Dahlias prefer a temperature range of 60 to 70 degrees Fahrenheit during the day and 50 to 60 degrees Fahrenheit at night. The Dahlia 'Trelyn Crimson' can survive temperature dips down to about 40 degrees Fahrenheit, but sustained cold can damage or kill the plant. Ideal growing conditions include warm days and cooler nights, avoiding extremes on either end of the temperature spectrum.

Pruning

Pruning your Dahlia 'Trelyn Crimson' helps direct energy to the most vigorous blooms and promotes better air circulation within the plant. Remove spent flowers regularly to encourage continuous blooming and cut back any weak or damaged stems. The best time to prune is in late winter or early spring before new growth begins. Prune the dahlias every few weeks during the blooming season to keep the plant looking its best and to promote larger flowers.

Cleaning

As needed

Soil

Dahlia 'Trelyn Crimson' thrives best in fertile, well-draining soil with a pH range of 6.5 to 7.0. A balanced mix of loamy soil amended with compost and peat moss can enhance growth. Perlite or sand added to the mix can improve drainage.

Repotting

Dahlias, including the 'Trelyn Crimson', should ideally be repotted annually, usually after winter dormancy before the new growth begins in early spring.

Humidity & Misting

Dahlias like 'Trelyn Crimson' prefer moderate humidity levels. Strive to maintain humidity around 60-70% for optimal growth, but they are adaptable to lower humidity conditions.

Suitable locations

• Indoor

  Ensure bright light, ample watering, and pot with drainage.

• Outdoor

  Plant in full sun, well-draining soil, and deadhead regularly.

• Hardiness zone

  8-11 USDA.

Life cycle

The Dahlia 'Trelyn Crimson', commonly known simply as Dahlia, begins its life cycle when a gardener plants a tuber in well-drained soil after the risk of frost has passed. The tuber germinates, and a sprout emerges from the soil, growing into a young plant with characteristic foliage. Throughout the growing season, the plant continues to develop, producing a robust stem and vibrant, crimson flowers that make it a popular ornamental specimen. After flowering, if the blooms are not deadheaded, they will eventually wilt and the plant will set seed. As cold weather approaches, the Dahlia enters a period of dormancy; the aerial parts die back and the tuber overwinters in the soil, or it is dug up, stored, and protected from freezing temperatures. In the following spring, the cycle can begin anew with the planting of either saved tubers or the new ones produced from the previous season’s growth.

Propogation

• Propogation time

  Spring to Summer

• The most popular method to propagate a Dahlia 'Trelyn Crimson' is through division of tubers. The optimal time to undertake this process is in the spring just before the new growth begins. To propagate by division, carefully lift the dahlia clumps from the ground after the foliage has died back post-frost. Using a sharp knife, divide the clump ensuring that each division has at least one eye or bud from which new growth can emerge. It's important to handle the tubers gently to prevent damage. Once the tubers are divided, they can be planted immediately in well-draining soil, positioned such that the eyes are just below the soil surface, approximately 2 to 4 inches deep (5 to 10 centimeters). This method allows for a straightforward and reliable means of increasing one's dahlia collection while preserving the genetic characteristics of the 'Trelyn Crimson'.
