Campanula, also known as bellflower (Campanula rapunculus), is a charming houseplant prized for its delicate, bell-shaped blooms that come in shades of purple, blue, and white. With its cascading growth habit and prolific flowering, Campanula adds a touch of elegance to any indoor space. While it is relatively low-maintenance, providing the right care will ensure your Campanula thrives and blooms abundantly. Here’s everything you need to know to care for this beautiful houseplant.
Campanula thrives in bright, indirect light. Place it near a sunny window, such as an east- or west-facing one, where it can receive morning or late afternoon sunlight. Too much direct sunlight can scorch its delicate leaves, while insufficient light may result in fewer flowers. If you’re growing Campanula indoors in a dimly lit area, consider using a grow light to supplement its light needs.
Campanula prefers consistently moist but well-draining soil. Water the plant when the top inch of soil feels dry, ensuring that excess water drains out of the pot. Be careful not to let the soil dry out completely, as this can cause the plant to wilt and stress. However, overwatering can lead to root rot, so strike a balance by checking the soil regularly and adjusting your watering schedule based on the plant’s needs and the humidity in your home.
For optimal growth, Campanula requires well-draining soil that retains some moisture without becoming waterlogged. A standard potting mix with added perlite or sand works well. Ensure the pot for your Campanula has drainage holes to prevent water from accumulating at the bottom. Repot your Campanula every 1-2 years or when it outgrows its container, ideally in the spring before its active growing season.
Campanula thrives in cool to moderate temperatures, ideally between 60-75°F (15-24°C). Avoid exposing it to extreme heat, cold drafts, or sudden temperature fluctuations. While it can tolerate average indoor humidity, it appreciates slightly higher humidity levels. If the air in your home is dry, consider misting the plant occasionally or placing it near a humidifier to mimic its natural environment.
Feed your Campanula with a balanced, water-soluble fertilizer every 2-4 weeks during the growing season (spring and summer) to encourage lush foliage and abundant blooms. Reduce feeding during the fall and winter months when the plant enters a period of rest. Be careful not to over-fertilize, as this can lead to salt buildup in the soil and damage the roots.
Regular pruning helps maintain the shape and health of your Campanula plant. Remove any yellowing or dead leaves and trim back spent flowers to encourage the plant to produce more blooms. Pinching back leggy stems can also promote bushier growth. Always use sterilized pruning shears or a fresh tool to prevent the spread of disease.
Campanula is considered non-toxic to pets, making it a safe choice for households with cats or dogs. However, it’s still a good idea to discourage pets from chewing on the leaves or flowers to avoid accidental damage to the plant.
To keep your Campanula blooming, provide it with consistent care and the right conditions. Ensure it receives enough light, water, and nutrients, and deadhead spent flowers promptly. After its initial bloom cycle, the plant may take a short rest before blooming again. With proper care, Campanula can flower multiple times throughout the year.
