Generally Campanula is trouble free when it comes to pests and diseases. It can have issues with slugs and snails, aphids, powdery mildew and rust. To prevent downy mildew you should try to prevent crowded and humid conditions. Properly space plants apart and get rid of any weeds. Water at the soil and try to prevent soil splashing from the soil onto the leaves. To combat aphids you can pick away the bugs with your hands and also wash the infested areas down with soapy water. To prevent rust try to prevent too much moisture sitting on the leaves by always watering at the ground and, if possible, watering in the morning to give the moisture time to evaporate off the surface during the day. You can spray you plant with Neem Oil or sulfur as well which works as a fungicide. There are a number of non-organic fungicides you can also purchase to protect your plants against Rust. For Slugs and Snails, it is important to keep the area around the plant debris free and as dry as possible, especially at night as slugs and snails love damp conditions. You can use barriers such as egg shells or copper wire to surround the plant to prevent slugs and snails reaching the leaves.

To begin with you will want to water the plant lightly, especially during dry periods. Once the roots have established, however, Campanulas need very little watering except in prolonged very dry periods.

Plant somewhere where the plant will receive around 6 hours of direct sunlight every day.

Campanulas can thrive in nutrient-poor but well-drained soil. If you have very clay-heavy or waterlogged soil you should mix in plenty of perlite to improve drainage.

Don't worry, this isn't a hungry plant so your food bills won't be going up! https://cdn.shopify.com/s/files/1/0513/3428/3424/files/pruning_3x_4d3eaf73-f629-45e0-87a5-6f14f5f005fc.png
