    Uses Notes: 

    Calibrachoa do not like to have constantly damp soil. They will do well in the ground only with good drainage. For most gardeners containers are the best use for Calibrachoa.

    Maintenance Notes: 

    Superbells® calibrachoa plants are easy to grow and will flower non-stop from planting to hard frost if simple maintenance tasks are performed. Growing Superbells in full sun to part sun is important for their strong growth and bloom performance. They do not require deadheading, meaning the removal of spent flowers, to stay in bloom all season.  

     

    Calibrachoa’s roots are sensitive to wet soil and extreme soil pH levels. For these reasons, they grow best in containers with a well-drained potting mix such as Proven Winners Premium Potting Soil. If your garden soil is well-drained and slightly acidic, you may be able to grow calibrachoa in the ground.

     

    Superbells calibrachoa thrive with average moisture and prefer the soil to dry out a little bit before they are watered again. They do not grow well and may develop root rot in soggy soil. However, do not let the plants wilt severely before watering again.

     

    Superbells perform best when fed regularly with Proven Winners plant foods. At planting time, in containers and landscapes, mix Proven Winners Premium Continuous Release Plant Food into the soil, following the rates specified on the packaging. Reapply halfway through the growing season.

     

    Additionally, Superbells should be fed with Proven Winners Premium Water Soluble Plant Food every third time you water or at least once per week according to the rates specified on the packaging.

     

    By midsummer, it will be time to trim up your Superbells. Trim the longest stems, bringing them in line with the others, taking care not to remove more than 20% of the plant. Follow up by feeding them with water soluble plant food to promote fresh new growth and blooms.
