If the soil is too compact, amend it with sand or perlite to improve its drainage. This plant prefers a consistently moist soil, but it does not tolerate waterlogged or soggy soil conditions.
Cultivation methods
Campanula draba Burm.f. is a highly versatile plant that can be grown in different soil types, including clay, loam, and sand. Growing this plant from seeds is a suitable option, and the propagation process should be done during the spring or autumn season. The plant requires adequate sunlight exposure and can be grown indoors or outdoors.
Watering needs
Campanula draba Burm.f. requires regular watering to maintain healthy growth. The plant must be watered once a week during the summer season and twice a month during winter. However, the water requirements may change depending on factors such as humidity levels, temperature, and soil type. Ensure that the soil is moist, but not waterlogged, to avoid root rot.
Fertilization
Campanula draba Burm.f. requires a balanced fertilizer to ensure proper growth and development. The plant should be fertilized with a slow-release organic fertilizer during the spring season. Regular fertilization should then be administered once a month during the growing season. Avoid over-fertilizing the plant as it may cause damage.
Pruning
Campanula draba Burm.f. requires minimal pruning, and it's mostly done to remove dead or damaged leaves and stems. Pruning should be done after the blooming period, either in late summer or early fall. The plant can be cut back to a third of its original size to encourage future growth. Always use sharp and sterile pruning tools to avoid the spread of disease.
Propagation of Campanula draba Burm.f.
Campanula draba Burm.f. can be propagated through various methods such as seed sowing, division, and cuttings.
Seed Sowing
Seeds of Campanula draba Burm.f. can be sown in spring or fall. The seeds should be sown in small pots or trays filled with a well-draining potting mix. The seeds should be covered lightly with soil and kept moist. Germination should occur within two to three weeks. Once seedlings have emerged, they should be gradually acclimated to the outdoor conditions before transplanting to their permanent location.
Division
Campanula draba Burm.f. can easily be propagated through division in spring or fall. The plant should be dug up and the root ball carefully separated into smaller sections ensuring that each section has enough roots and shoots to establish itself when transplanted. These sections should be planted immediately in their new location at the same depth as the original plant with adequate water and care.
Cuttings
Stem cuttings can be taken from Campanula draba Burm.f. in early summer when the plant is in its active growing phase. Cuttings should be taken from the tips of healthy non-flowering stems, each around 4 inches in length. The bottom leaves should be removed, and the cuttings should be dipped in a rooting hormone before planting in a well-draining potting mix. The cuttings should be kept moist and humid until roots develop within two to three weeks. Once roots have formed, the new plants can be gradually acclimatized and transplanted into their permanent location.
Disease Management
Campanula draba Burm.f. is a hardy plant that is susceptible to certain diseases. One common disease that affects this plant is powdery mildew. Powdery mildew is a fungal disease that can result in a white, powdery growth on the leaves of the plant.

Fungicides like Sulfur can be used to manage powdery mildew.
Root rot is another disease that affects Campanula draba Burm.f. Root rot is caused by fungal pathogens that thrive in wet soil and can cause the roots of the plant to rot. To manage root rot on Campanula draba Burm.f., it is essential to provide proper soil drainage and avoid overwatering the plant. Additionally, fungicides like Thiophanate-methyl can be used to manage root rot.
Pest Management
Campanula draba Burm.f. is also susceptible to pests. One common pest that affects this plant is aphids. Aphids are small insects that feed on the sap of the plant and can cause stunted growth and distorted leaves. To manage aphids on Campanula draba Burm.f., it is recommended to spray the plant with a mixture of water and insecticidal soap or neem oil. Additionally, introducing beneficial insects like ladybugs can help manage aphids naturally.
Another pest that affects Campanula draba Burm.f. is spider mites. Spider mites are tiny pests that feed on the plant's fluids, causing leaf discolouration and webbing. To manage spider mites on Campanula draba Burm.f., it is recommended to regularly spray the plant with neem oil or insecticidal soap and increase humidity levels around the plant.
