As for watering, the Dahlia prefers evenly moist soil, but they should not be in too wet soil. Be sure to water the plant regularly, especially when it is dry, but be careful not to drown the roots. To promote flowering, it is important to fertilize the plant.
Since the Dahlia Happy Days often grows large, it is a good idea to support the plant with bamboo canes or another plant support, for example, so that it stays upright and does not fall over due to the wind or its own weight. In addition, it is important to remove wilted flowers regularly to keep the plant blooming.
When the cold comes in autumn and winter, you should remove the Dahlia tubers from the ground. Dig them up carefully, dry them well and store them in a cool, dry place (around 5-10°C) in a box with dry sand or peat.
With this care, your Dahlia Happy Days could continue to bloom wonderfully and brighten up your garden!
