How tall do dahlias grow creme de cassis?

Dahlias are a beautiful and popular addition to any garden or landscape. One particular variety, the “Creme de Cassis” dahlia, is known for its stunning deep purple blooms and compact growth habit. When fully grown, the “Creme de Cassis” dahlia can reach a height of approximately 90cm (35 inches) with a spread of about 45cm (18 inches). This compact size makes it a great choice for smaller gardens or containers.

To get your “Creme de Cassis” dahlias to this height, it is important to provide them with the right growing conditions. Start by potting up the dahlia plants and keeping them in a frost-free environment until they are large enough to be planted outdoors. This will help protect the young plants from any potential frost damage and allow them to establish a strong root system.

Once the threat of frost has passed and the dahlias are ready to be planted, choose a sunny spot in your garden with well-draining soil. Dahlias thrive in full sun, so make sure the area you select receives at least 6-8 hours of direct sunlight each day. Prepare the soil by adding organic matter, such as compost or well-rotted manure, to improve its fertility and drainage.

When planting the dahlias, dig a hole that is slightly larger than the root ball and place the plant in the hole, making sure the top of the root ball is level with the soil surface. Backfill the hole with soil, gently firming it around the plant to eliminate any air pockets. Water the newly planted dahlias thoroughly to help them settle in.

As the dahlias grow, it is important to provide them with regular watering, especially during dry spells. Keep the soil consistently moist but not waterlogged, as excessive moisture can lead to rot or other fungal diseases. Applying a layer of mulch around the base of the plants can help retain moisture and suppress weed growth.

To encourage bushier growth and more flowers, you may want to pinch out the growing tips of the dahlias when they reach a height of around 15-20cm (6-8 inches). This will help promote the development of side shoots and result in a fuller, more compact plant.

In terms of maintenance, dahlias benefit from regular feeding throughout the growing season. Use a balanced fertilizer, following the manufacturer’s instructions for application rates and frequency. Deadhead the spent flowers to encourage continuous blooming and remove any damaged or diseased foliage to prevent the spread of pests or diseases.

The “Creme de Cassis” dahlia can reach a height of approximately 90cm (35 inches) with a spread of about 45cm (18 inches). By providing them with the right growing conditions, such as a sunny location, well-draining soil, and regular care, you can enjoy the stunning blooms of these dahlias in your garden or containers.
