When to Plant Bellflower?

The best time to plant bellflower depends on the type of plant and your climate. Generally, you can plant bellflower seeds indoors in late winter or early spring, and transplant them outdoors after the last frost. Also, sow bellflower seeds directly in the garden in late spring or early summer. If you are planting bellflower plants from nurseries or divisions, you can do so in spring or fall.

How to Care for Bellflower?

Bellflower is not a fussy plant and requires minimal care once established.

  • Water: Water bellflower regularly during the first year of growth, and then reduce watering once the plants are established. Bellflower can tolerate some drought, but avoid letting the soil dry out completely.
  • Sunlight: Prefers full sun to partial shade, depending on the species. Some varieties can tolerate more shade than others, but they will produce fewer flowers in low-light conditions.
  • Fertilizer: Bellflower does not need much fertilizer, but you can apply a balanced organic fertilizer once or twice a year in spring or summer to boost growth and flowering.
  • Soil: Likes well-drained, moist, fertile, and slightly acidic soil. Amend the soil with compost or organic matter before planting to improve drainage and fertility.
  • Prune: Bellflower benefits from regular pruning to maintain its shape and encourage more blooms. You can deadhead spent flowers to prolong the flowering season and prevent self-seeding.
  • Temperature & Humidity: Bellflower thrives in cool to mild climates with moderate humidity. It can tolerate some heat and cold, but avoid extreme temperatures that can stress or damage the plants.
  • Container: Bellflower can be grown in containers as long as they have adequate drainage holes and enough space for root development. If you live in a cold area, it’s a good idea to move the container indoors or to a sheltered location during the winter.

Types of Bellflower

Bellflowers come in various shapes and sizes, each with its unique characteristics. Some have trailing habits, making them perfect for hanging baskets, while others stand tall and proud in borders or as standalone specimens.

Popular Varieties

  • Campanula carpatica (Carpathian Bellflower): A low-growing variety with star-shaped flowers in shades of blue and white, ideal for rock gardens.
  • Campanula lactiflora (Milky Bellflower): Taller and more upright, this variety produces clusters of lavender-blue flowers and is excellent for cottage gardens.
  • Campanula persicifolia (Peach-leaved Bellflower): Known for its graceful, upright stems and large, bell-shaped flowers in shades of blue, pink, and white.
  • Campanula portenschlagiana (Dalmatian Bellflower): A trailing species perfect for ground cover, producing masses of violet-blue blooms.

Each variety has its unique charm, making it easy to find the perfect bellflower for your garden.

How to Propagate Bellflower?

If you love bellflowers as much as I do, you might want to propagate them and spread their beauty all over your garden. There are three main ways to do that: seed, division and stem cuttings.


This is the easiest and cheapest method, but also the slowest. Collect the seeds from your existing bellflowers or buy them from a nursery. Sow them in a tray filled with moist potting mix in early spring, and cover them lightly with soil. Keep them in a warm and bright place, and water them regularly. You should see some sprouts in a few weeks. When they are big enough, you can transplant them to your desired location.


This is the fastest and most reliable method, but also the most invasive. Divide your bellflowers every two or three years in spring or autumn when they are not blooming. Dig up the whole plant carefully, and use a sharp knife to cut it into smaller sections. Make sure each section has some roots and shoots. Replant them immediately in well-drained soil, and water them well.

Stem cuttings

This is the most fun and creative method, but also the most challenging. Take stem cuttings from your bellflowers in late spring or early summer when they are actively growing. Choose healthy and non-flowering stems, and cut them about 10 cm long. Remove the lower leaves, and dip the cut end in some rooting hormone. Insert them in a pot filled with moist sand or perlite, and cover them with a plastic bag. Keep them in a bright but indirect light, and mist them daily. You should see some roots in a few weeks. When they are well-rooted, you can pot them up or plant them out.

Bellflower Pests and Diseases


Bellflowers are beautiful plants that attract bees, butterflies, and hummingbirds to your garden. But they also attract some unwanted visitors, such as slugs, snails, aphids, and spider mites. These pests can damage the leaves, stems, and flowers of your bellflowers, making them look less appealing and reducing their vigor.

To prevent and control these pests, use some natural methods, such as hand-picking, trapping, spraying with water or soap solution, or applying diatomaceous earth or neem oil.


Bellflowers are generally healthy plants that can resist most diseases. However, they can sometimes suffer from fungal infections, such as powdery mildew, rust, and leaf spot. These diseases can cause white, yellow, or brown spots on the leaves and stems of your bellflowers, and may also affect the flowers.

To prevent and control these diseases, keep your bellflowers well-spaced, water them at the base, avoid overhead watering, prune any infected parts, and apply fungicides if necessary.

Main Values of Bellflower
