Planting

From Early Spring TO Mid Spring

Plant bellflowers in full sunlight and cut back tall plants or move large structures that create shaded conditions around them. Lay a 2 to 3 inch layer of organic mulch, such as straw or pine needles, to the soil surrounding the campanula and some into the planting hole beneath the root ball; do not press it directly against the plant's stem. Campanula plants grow well without mulch, but it helps soil retain water and deters weeds.

 

Propagation by seed

From Mid Spring TO Late Spring

Campanula can grow from seed or from rhizomes. The tiny seeds should go in prepared soil in spring after all danger of frost has passed. Make sure to keep seedlings moderately moist when caring for bellflowers. To plant rhizomes, sever them from the parent plant at a root node and bury the roots in the soil.

 

Flowering

From Early Summer TO Early Autumn

Bellflowers will bloom heaviest in early to mid-summer but can delight you with flowers all the way into Autumn in some areas.
