PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The best time to plant Dahlia ‘Happy Days Yellow’ is in spring, once the soil has warmed up and the risk of frost has passed. This gives the plant the best chance to establish its roots before the blooming season begins.
Autumn: You can also plant Dahlia ‘Happy Days Yellow’ in early autumn. This allows the plant to settle in before the colder months, ensuring strong growth when the new growing season begins.
Site Selection
Sunlight: Dahlia thrives in full sun. Choose a location that receives at least 6 hours of direct sunlight per day to promote the plant’s growth and flower production. This ensures the bright yellow blooms are vibrant and abundant.
Soil: Dahlia prefers well-drained soil. Avoid areas where the soil tends to become waterlogged, as the plant can suffer from root rot. Improve drainage by incorporating organic matter such as compost into the soil.
Planting Instructions
Prepare the Hole: Dig a hole approximately 3 inches deep for your Dahlia tuber. The hole should be wide enough to comfortably accommodate the tuber, allowing space for the roots to spread.
Soil Preparation: Mix compost or organic matter into the soil to improve fertility and drainage. This helps provide the nutrients Dahlia ‘Happy Days Yellow’ needs for strong, healthy growth and vibrant blooms.
Planting: Place the tuber in the prepared hole, making sure the “eyes” (small growth points) are facing upwards. Gently cover the tuber with soil, firming it down to remove any air pockets.
Watering After Planting: Water thoroughly after planting to settle the soil around the tuber. Ensure the soil drains well, as Dahlia does not like sitting in waterlogged conditions.
Watering Requirements
Growing Season: During the growing season, Dahlia requires consistent moisture. Water deeply, allowing the soil to dry out slightly between waterings. Avoid overwatering to prevent root rot.
Dormant Season: In the dormant season, reduce watering significantly. Only water if the soil becomes excessively dry. Dahlia requires minimal moisture during this time.
Feeding
Spring: Apply a balanced fertiliser in early spring before the growing season begins. This helps your Dahlia establish a strong root system and encourages healthy growth and blooms.
Mid-Summer: A light application of slow-release fertiliser in mid-summer will help maintain healthy growth and encourage continued blooming. This ensures the plant thrives throughout the growing season.
Pruning
Deadheading: To encourage more blooms and prolong the flowering season, regularly deadhead your Dahlia ‘Happy Days Yellow’. Remove spent flowers to keep the plant looking tidy and prevent energy from going into seed production.
Autumn Pruning: After the blooming season, trim back your Dahlia to just a few inches above ground level. This prepares the plant for dormancy and promotes strong growth the following year.
Mulching
Spring: Apply a layer of mulch around the base of Dahlia ‘Happy Days Yellow’ in spring. Mulch helps retain moisture, suppresses weeds, and regulates soil temperature, which is crucial for establishing healthy growth.
Winter: In colder climates, adding a thicker layer of mulch around the base of your Dahlia will protect the tubers from frost damage and ensure the plant survives the winter months.
Supporting the Plant
Staking: As Dahlia ‘Happy Days Yellow’ grows, it may require staking, particularly in windy conditions or if the plant grows tall. Use plant supports to keep the stems upright and prevent them from breaking.
Final Tips
Dahlia ‘Happy Days Yellow’ is an easy-to-grow plant that adds a splash of vibrant yellow colour to your garden. By choosing a sunny location with well-drained soil and following this care guide, you can ensure your Dahlia will thrive throughout the growing season, from midsummer to autumn. This stunning dahlia is perfect for garden beds, containers, or as a cut flower, providing long-lasting beauty for your outdoor space.
