Dahlia 'Scarlet Fern' Dahlia 'Scarlet Fern' (Sin)

Water

For Dahlia 'Scarlet Fern', ensure the soil is moist but not waterlogged by checking the top inch of the soil; if it's dry, it's time to water. During the active growing season, typically from spring to fall, water the plant thoroughly once or twice a week with about one to two gallons of water, depending on the size of the plant and the weather conditions. Decrease watering during the winter months when the plant is dormant. Always use a watering can or a hose with a gentle nozzle to avoid damaging the foliage and flowers, and water at the base of the plant to keep the leaves dry and prevent fungal diseases.

Light

Dahlias, including the 'Scarlet Fern' variety, thrive best in full sun conditions, so place the plant in a location where it receives at least 6 to 8 hours of direct sunlight daily. Avoid areas that are prone to extended periods of shade, as this can reduce blooming and weaken the plant. An ideal spot is a south or west-facing location where the plant is exposed to plenty of sunlight throughout the day.

Temperature

Dahlias such as the 'Scarlet Fern' prefer temperate climates with daytime temperatures ranging between 70 to 85 degrees Fahrenheit and nighttime temperatures not falling below 60 degrees Fahrenheit. Although the plant can survive a brief period of colder temperatures down to about 50 degrees Fahrenheit, constant exposure to temperatures below this can harm the plant. Protect dahlias from extreme heat by providing some afternoon shade when temperatures exceed 90 degrees Fahrenheit.

Pruning

Pruning is vital for Dahlias, including 'Scarlet Fern', to encourage vigorous growth and abundant flowering. Deadhead spent flowers regularly to stimulate new blooms. At the beginning of the growing season, pinch the tips of the main shoot to promote bushier growth and more stems for flowers. Pruning should be done with clean, sharp shears, and for this type of dahlia, it's best to prune in early spring before the new growth starts, and throughout the growing season as necessary for shaping and deadheading.

Cleaning

As needed

Soil

Dahlia 'Scarlet Fern' prefers well-draining, fertile soil with a pH range of 6.5 to 7.0. A good mix would consist of equal parts garden soil, peat moss, and perlite or sand to ensure proper drainage. Regular organic matter amendments will enhance soil quality and plant health.

Repotting

Dahlias, including 'Scarlet Fern', typically need to be repotted every spring before new growth starts. Tubers should be divided and replanted to refresh the soil and provide space for growth.

Humidity & Misting

Dahlias like 'Scarlet Fern' prefer moderate humidity levels but are adaptable and do not require specific humidity conditions for success. However, ensuring good air circulation around the plants can prevent humidity-related issues.

Suitable locations

• Indoor

  Provide bright light, good airflow, and pot in well-draining soil.

• Outdoor

  Plant in full sun, rich soil, ensure space for growth.

• Hardiness zone

  8-11 USDA

Life cycle

Dahlia 'Scarlet Fern' begins its cycle with seed germination, which occurs in a warm, moist soil environment, usually in late winter or early spring. Once the seeds sprout, the young seedlings are carefully tended until they establish a set of true leaves and can be transplanted to their final growing location. The plant then enters a vigorous vegetative growth stage, producing lush foliage and strong stems as temperatures increase. Following vegetative growth, the Dahlia 'Scarlet Fern' enters the flowering stage in late summer or early fall, where it produces its characteristic bright, fern-like scarlet petals which attract pollinators. After flowering, as the season cools, the plant sets seeds or can be propagated through tuber division before it enters dormancy during winter. In regions with harsh winters, the tubers are commonly dug up and stored until the next growing season to protect them from frost damage.

Propogation

• Propogation time

  Spring-Early Summer

• Propogation: The most popular method of propagation for the Dahlia 'Scarlet Fern', also known simply as Dahlia, is through division of tubers. This is typically done in the spring just before or as new growth starts to appear from the tubers. Gardeners should carefully dig up the clump of tubers, making sure not to damage them. Using a sharp, clean knife or spade, they can divide the clump into smaller sections, ensuring that each section has at least one eye, which is a growing point. It is important to let the cut surfaces dry for a few days to form a protective callus before planting. The divided tubers are then planted about 4 to 6 inches (10 to 15 cm) deep in well-draining soil with the eyes facing upwards. This method of propagation allows for the production of exact clones of the parent plant, retaining its unique characteristics.
