Bellflowers are a perennial flower that comes in a variety of different colors and shapes. The most common color of bellflowers is blue. The blue flowers are usually referred to as bluebells and are very popular in the mid-southeast. Bellflowers require a well drained, very wet soil. This can encourage rot and a thinning of the flower during winter months. Bellflowers rarely need to be fertilized. When the flowers are fertilized the plant can become too aggressive and take over a flower bed. Typically bellflowers are easy to grow and require little maintenance.
Choose an area to plant your bellflowers so that they will get full sun or at least only partial shade. Mix a good organic compost into the soil before you plant your seeds. Bellflowers need the soil to have an average pH of around 5.1 in order for the plants to be successful. Soil should not be allowed to get dry but instead should be kept moist. This will keep your flowers blooming for a long time.
Plant your bellflowers in spring or fall when the months are cooler. Dig a hole approximately the same depth as the pot that your flowers are in, this will typically be around 12 inches. Take the bellflowers out of the pot and break up the roots until they are separated. Place the seedling into the hole and fill it back up with soil. Cover the soil with about 2 inches of mulch to help hold the water in and to control weeds around the plants. Plants should be planted 12 inches apart.
Remove dead flowers after they have bloomed and died. This will help the other flowers bloom. In the spring you should cut the flower stems all the way to the base to encourage new growth. Pruning back the flowers will help it grow. If you prune the flowers at a different time of the year there will be less flowers in the succeeding year. The plant will not be hurt but it will take several years to see a lot of flowers in bloom.
Thin out your flowers every few years and replant the new growth. This will help grow your flower bed while keeping your bellflowers healthy.
