Whether you are interested in its propagation methods, its suitability for container gardening, or its susceptibility to specific diseases and pests, this comprehensive guide has got you covered.



The Campanula ‘Viking’ thrives when provided with moderate levels of water. It is essential to maintain consistent moisture levels in the soil, particularly during the plant’s active growth period. However, it is equally important to ensure that the soil does not become waterlogged, as this can lead to root rot and other moisture-related issues. When watering the plant, aim to keep the soil evenly moist but not saturated. In general, a deep watering once or twice a week is sufficient, but this can vary depending on the climate and soil conditions.


When it comes to sunlight requirements, the Campanula ‘Viking’ performs best in full sun to partial shade. While it can tolerate some shade, providing the plant with at least 4 to 6 hours of direct sunlight per day will promote healthy growth and abundant flowering. In regions with hot summers, providing the plant with some afternoon shade can help protect it from the intense heat and prevent wilting. However, it is important to strike a balance, as too much shade can lead to reduced flowering and leggy growth.


The Campanula ‘Viking’ benefits from a balanced, water-soluble fertilizer that is applied during the growing season. It is advisable to use a fertilizer with equal NPK (Nitrogen, Phosphorus, Potassium) ratios, such as 10-10-10 or 20-20-20, to provide the plant with essential nutrients for healthy growth and flowering. Fertilizing the plant every 4 to 6 weeks during the growing season will help maintain its vigor and promote prolific blooming. However, it is important to avoid over-fertilization, as this can lead to excessive vegetative growth at the expense of blooms.


The Campanula ‘Viking’ thrives in well-draining, fertile soil that is rich in organic matter. The ideal soil type for this plant is loamy and slightly acidic to neutral in pH. It is important to ensure that the soil provides good drainage, as waterlogged conditions can lead to root rot and other problems. Amending the soil with compost or well-rotted manure can help improve its structure and fertility, providing an optimal growing medium for the Campanula ‘Viking’. Additionally, a layer of mulch around the plants can help conserve soil moisture and suppress weed growth.


Regular deadheading is essential for maintaining the appearance and vigor of the Campanula ‘Viking’. Deadheading involves the removal of spent flowers, which not only enhances the plant’s aesthetic appeal but also encourages it to produce more blooms. To deadhead the plant, simply pinch or snip off the faded flowers, taking care to remove the entire flower head along with the stem. This practice should be carried out throughout the blooming season to prolong the display of flowers and prevent the formation of seeds, which can divert the plant’s energy away from flowering.


The Campanula ‘Viking’ can be propagated through division, making it a relatively easy plant to multiply and share with others. Division is best carried out in the spring or early fall, when the plant is actively growing and the weather is mild. To propagate the plant through division, follow these steps:

  1. Begin by carefully digging up the entire plant, taking care not to damage its roots.
  2. Gently separate the clumps of the plant into smaller sections, ensuring that each division has a healthy root system and several shoots or growth points.
  3. Replant the divided sections in prepared soil, ensuring that they are positioned at the same level as they were previously growing.

After being replanted, the divisions should be kept well-watered and provided with appropriate sunlight and care to encourage their establishment and growth.

Container Popularity

The Campanula ‘Viking’ is popular among gardeners for its suitability for container gardening. Its compact growth habit and charming flowers make it an excellent choice for adding color and elegance to patio, balcony, and courtyard gardens. When growing the Campanula ‘Viking’ in containers, it is essential to select spacious pots with adequate drainage holes to ensure that the plant’s roots have room to spread and excess water can easily escape. To promote healthy growth, use a high-quality potting mix that provides good aeration and moisture retention. Container-grown Campanula ‘Viking’ plants may require more frequent watering than those grown in the ground, as the soil in pots can dry out more quickly.

Common Diseases

Disease Diagnosis

While the Campanula ‘Viking’ is generally resistant to most diseases when grown in appropriate conditions, it can be susceptible to certain issues, particularly if its cultural requirements are not met. Two common diseases that may affect the plant are powdery mildew and leaf spot.

  • Powdery Mildew: Powdery mildew is a fungal disease that manifests as a powdery, white coating on the leaves and stems of plants. It thrives in humid conditions and can weaken the plant if left unmanaged. To prevent powdery mildew, it is essential to provide good air circulation around the plants, avoid overhead watering, and promptly remove and dispose of any affected plant parts.

  • Leaf Spot: Leaf spot is another fungal disease that can affect the Campanula ‘Viking’, causing dark spots to form on the foliage. This disease is favored by wet conditions and can be managed by ensuring that the plants are not excessively wet and by promptly removing and disposing of any infected leaves.

Common Pests

Botanist’s Tips

  • Provide Support for Tall Varieties: Some varieties of the Campanula ‘Viking’ can reach considerable heights and may benefit from support to prevent them from flopping over. Using discreet stakes or cages can help keep the plants upright and prevent damage to their stems and flowers.

  • Mulch around the Plants: Applying a layer of organic mulch, such as bark chips or shredded leaves, around the base of the Campanula ‘Viking’ plants can help conserve soil moisture, suppress weed growth, and maintain a more stable soil temperature.

  • Deadhead Spent Blooms: Regular deadheading is not only beneficial for the plant’s appearance and flowering performance but also helps divert its energy into producing more blooms rather than setting seeds.

Fun Facts

  • The Campanula ‘Viking’ is known for attracting pollinators such as bees and butterflies with its abundant nectar and appealing flowers.
  • It is a low-maintenance plant that adds a touch of elegance to any garden or landscape.

Throughout the blooming season, the Campanula ‘Viking’ attracts various pollinators with its nectar-rich flowers, making it a delightful addition to wildlife-friendly gardens. Its low-maintenance nature also makes it a preferred choice for both novice and experienced gardeners.
