Dahlia Dahlia 'Karma Fiesta' (PBR) (D)

Water

Dahlias require consistent moisture and should be watered deeply at least twice a week, allowing the soil to dry out slightly between waterings. For 'Karma Fiesta' Dahlias, provide about 1-2 gallons per week depending on weather conditions. In hot, dry spells, you may need to water more frequently, especially if the plant is in a container. Make sure the water penetrates deeply into the soil to encourage strong root development; shallow watering can lead to weak growth. Avoid overhead watering to minimize the risk of fungal diseases; instead, water at the base of the plant.

Light

Dahlias thrive in bright, direct sunlight and the 'Karma Fiesta' Dahlia is no exception. It is best grown in a location where it receives at least 6 to 8 hours of sunlight each day. The ideal spot is one that gets morning sunlight and partial shade during the hottest part of the day to protect the blossoms from fading. Avoid overly shaded areas as they can inhibit flowering and lead to weak, leggy growth.

Temperature

Dahlias like 'Karma Fiesta' perform best in a temperature range between 60 and 75 degrees Fahrenheit. They can survive minimum temperatures down to about 50 degrees Fahrenheit, but they stop growing if temperatures dip below this point. They are not frost-tolerant and can be damaged or killed by temperatures below 32 degrees Fahrenheit. Ideal growth and flowering occur when the temperature remains within the optimal range during the growing season.

Pruning

Pruning helps maintain the shape of the 'Karma Fiesta' Dahlia, encourages larger blooms, and prevents disease by increasing airflow. Deadhead spent flowers regularly throughout the blooming season to promote continuous flowering. Cut back the stems to about 2-3 inches above the ground level after the first frost in the fall when the plant begins to die back. This is also the time to dig up tubers in colder regions for winter storage.

Cleaning

As needed

Soil

Dahlias thrive in a rich, well-draining soil mix with a pH range of 6.5 to 7.0. A recipe for Dahlia 'Karma Fiesta' would be a blend of two parts loam, one part peat moss or coco coir, and one part perlite to ensure adequate drainage and soil aeration. Amend with compost for nutrient richness.

Repotting

Dahlias, such as 'Karma Fiesta', generally require repotting when they outgrow their current container or when the tubers are divided after the growing season. Typically, this means repotting every year during early spring before new growth begins.

Humidity & Misting

Dahlias like 'Karma Fiesta' do best in moderate humidity levels. Aim for a relative humidity of about 40-60%. Avoid overly humid conditions as this can promote fungal diseases.

Suitable locations

• Indoor

  Place Dahlias in bright, indirect light and keep soil moist.

• Outdoor

  Plant in full sun after frost, in fertile, well-drained soil.

• Hardiness zone

  8-11 USDA

Life cycle

The Dahlia 'Karma Fiesta', commonly known as Dahlia, begins its cycle as a tuber planted after the last frost when the soil has warmed. It quickly sprouts and grows, producing a sturdy stem and lush foliage; during this vegetative stage, the plant develops its complex root system. As summer progresses, the plant enters the flowering stage, blooming profusely with vibrant, multicolored flowers that are attractive to pollinators. After pollination, if conditions allow, the plant may produce seeds, but many cultivated dahlias are sterile and propagated mainly from tubers. With the onset of autumn and cooler temperatures, the Dahlia 'Karma Fiesta' enters senescence, where the aerial parts of the plant begin to wilt and die back. Before winter, the tubers are typically dug up and stored in a cool, frost-free place to overwinter and be replanted the following spring, repeating the cycle.

Propogation

• Propogation time

  Spring-Early Summer

• Propogation: Dahlia 'Karma Fiesta' can be propagated effectively through the division of tubers. Ideally, this is done in the spring just before the new growth begins. To do this, you must carefully dig up the clump of tubers taking care not to damage them. Look for the swollen, bulb-like structures which are the tubers and ensure that each division has at least one eye, which is a point on the tuber from which new growth can emerge. Once you have divided the tubers, plant them about 6 to 8 inches deep (15 to 20 centimeters) in well-drained soil with the eyes facing upwards. Water the tubers well after planting and continue to care for them as they grow, ensuring they receive adequate water and are not subjected to frost, as Dahlia tubers are sensitive to cold temperatures.
