    Bright, cheery yellow blooms cover this mounding trailing calibrachoa plant. Superbells are best grown in containers where soil moisture can be more easily controlled, since they don't tolerate constantly wet soils well.

    Uses Notes: 

    Superbells 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 mounding trailing 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.

    • Our yellow Superbells are wonderful in our window boxes with some purple trailing verbenas. They are in full sun in the morning, shade later. Very pleased with them. Last year was the first year I grew this plant (in a hanging basket) and it sold me, it was loaded with blooms all summer. Really easy to grow.

    • I purchased these knowing that Proven Winners flowers are always superior. These are a disappointment as they are very small, sparse blooms. I haave the correct temp, fertilizer and soil. Disappointed. Will toss them and replace with Supertunia. You have spoiled us!

    • I planted 10 of these Superbells Yellow in the railing planters on my deck. They are located in full sun, Zone 6b. All of the other plants in my railing planters (Coleus, Supertunias, Dichondra, Spikes, etc.) are doing fantastic and growing very well. However, the Superbells Yellow have lacked in vigor and color. The Superbells have remained very small, significantly smaller than my other plants, and they flish out of bloom and lose color. They only had color for a few weeks after being planted. I am planning on replacing them with yellow Supertunias, maybe Supertunia Limoncello or Mini Vista Yellow. Overall, I am disappointed and unimpressed with the Superbells Yellow.
