  • water dropWater

    Dahlias require a steady supply of water to flourish. It's essential to water them deeply once or twice a week, providing about 1-2 gallons per plant depending on the weather conditions; more frequent watering may be necessary during dryer periods. Always water at the base of the plant to keep the foliage dry and reduce the risk of fungal diseases. The soil should be moist but not saturated, as Dahlias do not like to sit in waterlogged soil. During peak blooming season, consistent watering is vital to support their vigorous growth and large flower production.

  • sunLight

    Dahlias thrive in full sun, with at least 6 to 8 hours of direct sunlight each day. The ideal spot for a Dahlia 'Yelno Harmony' is in a sunny area where it can receive plenty of light without being shaded by larger plants or structures. Too little light can lead to weak stems and poor blooming.

  • thermometerTemperature

    Dahlias prefer moderate to warm conditions and do best in temperatures between 60°F and 75°F. They can survive minimum temperatures of around 50°F, but they should be protected from frost, which can damage or kill the plant. Ideal growing conditions include warm days and cooler nights.

  • scissorsPruning

    Pruning Dahlias is important to promote bushier growth and more blooms. Pinch out the center shoot above the third set of leaves when the plant is about a foot tall to encourage lateral branching. Deadhead spent flowers regularly to encourage continuous blooming. The best time for pruning is throughout the growing season, as needed.

  • circleLife cycle

    Dahlia 'Yelno Harmony' begins its life cycle when the tubers are planted in the soil after the last frost of the spring. The plant emerges as seedlings and develops into a vegetative state with a foliage of green leaves. As it matures, it enters the budding stage where flower buds appear and eventually bloom into vibrant yellow flowers typically in mid-summer to early fall. After the blooming period, the flowers will wither, and if left unattended, the plant may set seed. As autumn approaches, the plant enters dormancy; the foliage dies back, and the tubers can be dug up and stored over the winter in a cool, dry place. The cycle begins anew when the tubers are replanted after the frost the following spring.

      Spring to Summer

    • The popular method of propagation for Dahlia 'Yelno Harmony' involves taking basal cuttings in the spring. As the new growth appears at the base of the plant, cuttings of about 3-4 inches (7.6-10.2 cm) can be taken from the tubers that are sprouting. These cuttings are then gently removed with a piece of the tuber attached, ensuring that each cutting has at least one growth point. The cuttings should be placed in a well-draining soil mix and kept in a warm, humid environment to encourage rooting. Roots typically develop within a few weeks, after which the new dahlia plants can be transferred to larger pots or planted directly into the garden once the threat of frost has passed.
