Growing Campanula White Wonder®

Latin Name Pronunciation: kam-pan'yew-luh 

LIGHT: Place your Bellflower (Campanula x haylodgensis White Wonder®) by a window where it will receive ample sunlight (at least 6 hours a day of direct sunlight on the plant). A south-facing window is usually best.

WATERING: Keep the potting mix moist, but do not allow the pot to sit in water for more than an hour. The simplest way to water is bring the pot to a kitchen sink, water thoroughly (until the excess drains from the bottom of the pot), then return the pot to the saucer. It’s time to water when the top ½ inch of the potting mix feels dry to the touch.

TEMPERATURE: Campanulas are adaptable to a wide range of temperatures, however, if you live in a very warm climate, protect your plant from hot afternoon sun.

FERTILIZER: We recommend that you fertilize potted plants every 2-4 weeks during the growing season (generally April into September), and that you withhold fertilizer entirely during fall and winter, when most plants rest. Use a balanced, water-soluble fertilizer designed for houseplants (such as 20-20-20, available at garden centers), mixed at half the rate suggested by the manufacturer.

AFTER CARE: If you live in Zones 5-8, you may plant your Campanula in the ground once the danger of frost has passed in spring. Choose a site in full sun to partial shade with evenly moist but well-drained soil. Once established in your garden, your plant will flower from mid spring to early summer. Trim back spent flowers.

If you live in a very warm climate, you can continue to grow your plant in a pot. After several months, the plant may benefit from being repotted into a larger container (choose one that is about 2 inches larger in diameter).
