When to Plant

Calibrachoas can be purchased as plug plants, and so can be grown from early spring or even up to summer if you purchase them as garden-ready plugs. Grow them indoors until mid-May, when the last frost has passed.

How to Plant

Our modules and plug plants are incredibly easy to plant and grow. Whether you’re growing them directly outside into the border or into a container, our pot-grown plants are a breeze from the moment they arrive.   
- Dig a hole in the border that’s big enough to house the root system. If planting in pots, fill a large pot halfway with potting soil and then make a well in the middle. Do this until the top of the soil from the plant is just below the top of the pot.  
- Wedge in the plant by adding soil to the gaps in the hole, firming down the surface to ensure it’s in place.  
- Water well and you’re done!

Where to Plant

Calibrachoas are the ideal bedding plant. Many trail, giving an impressive display throughout summer. We suggest planting your calibrachoa in containers and hanging baskets to get that beautiful trailing effect. They can be grown in the ground, but you’ll miss out on that gorgeous tumbling display.  
Position them somewhere that’s sheltered but gets plenty of sunshine. They can stand very light shade if necessary. 

When to Water

Water calibrachoa regularly, especially if they’re in containers. These drain freely and can cause the soil to become dry. Feed every few weeks with a high potash feed and throw them in the compost at the end of their flowering season.


There is no need to deadhead calibrachoa plants as they are ‘self-cleaning’, which means that spent flowers will drop off automatically. 


Calibrachoa is an annual summer plant, so they’re not frost hardy. Add spent plants into your compost or dispose in the garden waste bin. 


As Calibrachoa is a hybrid plant, they don’t produce seeds. The best and most cost-effective way to grow new calibrachoa plants is to buy them from your favourite garden centre.

Common Issues & How to Solve Them

If your calibrachoas are struggling to flower, then it could be because they’re in too much shade. Calibrachoas need up to six hours of sun a day to flower. They could also wilt due to high temperatures or a lack of water.

When do they Flower?

Calibrachoas can flower for long periods of time if kept in good shape. You can see your gorgeous blooms any time between April and October!
