bonnet bellflower

Bonnet bellflower (Codonopsis lanceolata) should be watered deeply and slowly to thoroughly moisten the soil and to promote root growth. Water should be applied about every 5-7 days in warmer weather, or every 2-3 weeks in cooler weather. The soil should be checked before each watering to make sure it is not oversaturated. If the top inch of soil is dry, it’s time to water. Water slowly until it just begins to run off to ensure that the water has fully penetrated the soil. Allow any excess water to drain away and discard.

Bonnet bellflower plants prefer direct sunlight for a good amount of the day. They should get at least 6 hours of direct sunlight between the hours of 10:00am to 4:00pm. During the times of intense summer heat, you may want to provide some afternoon shade to protect your bonnet bellflower plant.

Bonnet bellflower should be pruned once annually, during the late winter or early spring. Pruning should involve removing any dead, fading, or damaged stems, as well as any stalks that are overlapping to create a neat and orderly form. To promote flowering, the plant should also be thinned out and re-shaped. Do not remove more than 30% of the plant’s foliage. Some light pruning can also occur during the growing season to help shape and encourage bushy vegetation.
