• Few plants put on a show like Dahlia Grandalia. With its big showy flowers and long flowering season, it’s a simple way to bring bright colour to beds, borders and patio containers from summer until the first frosts. Grow it on its own or mixed with other late-season favourites, this dahlia packs a punch wherever you grow it.
• Suited to sunny gardens, regular deadheading will be rewarded with a constant display of flowers. It has thick stems which make it a great cut flower, so you can enjoy fresh blooms in the garden and in the house.
• Plant in fertile well-drained soil after danger of frost is past, in a location that receives plenty of sun. During dry spells water and feed regularly throughout the growing season to encourage vigorous growth and an abundance of flowers. Removing faded blooms will allow the plant to produce new buds for weeks on end.
• A great option for filling a cottage garden border, brightening containers on a patio or just looking for a dependable splash of colour is Dahlia ‘Grandalia’. It’s easy to grow, generous with its flowers and a variety that keeps the garden looking its best long after many other summer plants have finished blooming.

Watering Water thoroughly after planting and keep the soil evenly moist while the plant establishes. Once established, water during prolonged dry periods rather than little and often, allowing the soil to drain between waterings. Container-grown plants should be checked more frequently in warm or windy weather.

Best Growing Conditions Grow in sun or partial shade in well-drained soil. Choose a position with good airflow and enough space for the plant to reach its mature size. Protect from hard frost and cold, drying winds, especially while young or when grown in containers.
