When to Plant

Ideally, we would recommend planting your campanula in spring to autumn when the risk of heavy frosts is over (mid-late April to late October).

How to Plant

Planting Modules & Pots 
 Our modules and pots are easy to plant. Whether you’re growing them directly outside into the border or in a container, our pot-grown plants and modules are a breeze from the moment they arrive.  
- Dig a hole in the border that’s big enough to house the entire module. If planting in pots, fill a large pot halfway with potting soil and then make several holes that can hold the modules. Do this until the top of the soil from the module is just below the top of the pot. 
- Fill around the modules with soil and firm them down gently.  
- Water well and you’re done!  

Where to Plant

Ensure your Campanula is planted in full sun and well-drained soil. Campanulas, especially mat-forming varieties, are competitive plants and may overpower small ones. With this in mind, try planting them somewhere that gives them plenty of space to grow. 

When to Water

Water Campanulas well once planted. After that though, water them through dry periods, or when the first two inches of soil feels dry to the touch. 


Your Campanula doesn’t need to be deadheaded to thrive. However, you can trim back faded blooms to keep their appearance nice and tidy.

Common Issues & How to Solve Them

These plants are relatively disease free. Take precautions against slugs and snails, though, as they might take a particular interest. Sprinkle grit, broken shells or something sharp to the base of the plant to stop them from reaching it.  
If you find a powdery white residue on the underside of the leaves, then you may have found powdery mildew. This can happen to a plant that’s grown in less-than-ideal conditions. Cut back affected plants or leaves and dispose of them so they can’t infect any other plants. You can also add mulch to stop the remaining spores from reaching the plants come spring. 

When will they Flower?

Your Campanulas will flower from mid to late summer. This is often from July to August but may depend on each variety.
