Calibrachoa Seeds: A Closer Look

Calibrachoa, also known as million bells or trailing petunia, is a profuse blooming plant that blooms from early spring until late autumn.

Although in Zones 9-11, it exhibits winter hardiness, gardeners typically cultivate it on an annual basis.

Calibrachoa’s trailing stems are covered in bright, petunia-like blooms, making it ideal for hanging baskets, pots, or ground cover.

Growing Calibrachoa from seed is now possible because of the development of Kabloom series seeds.

It likes well-drained soil, as well as consistent watering and feeding. Furthermore, because these plants are self-clean, they require little upkeep.

How to Collect the Calibrachoa Seeds?

1. Collection

Look for seed pods beneath the blossoms to harvest calibrachoa seeds. Well-pollinated blooms will produce seed pods that can be dried on the plant.

Just crack apart the dried pods to gather the small, black calibrachoa seeds. To release the seeds, pluck or pinch off dried seed pods and smash them over paper.

Remember that not all calibrachoa cultivars yield seeds, so look for seed pods when the flowering season ends. Depending on the hardiness zone, hybrid calibrachoas can be annual or perennial.

2. Storage

A. Breaking and Crushing Pods

Breaking and crushing pods can be a useful way to gather seeds. You may conveniently extract the small seeds by picking the seed pods and gently breaking them over the paper.

Shake the pods to get the seeds to fall onto the paper. You may also crush the pods to retrieve the seeds if necessary.

This method makes it easier and faster to extract seeds from the pods of your selected plants.

B. Drying Pods

Drying pods is important in keeping seeds or utilizing them for other purposes. If the pods need to be sufficiently dry, you can continue drying them for another week or longer, depending on their moisture level.

Arrange the pods in a single layer into a shallow cardboard box and store it somewhere dry and warm.

This favorable atmosphere will aid in further drying and guarantee that the pods attain optimum dryness.

C. Transferring

To store calibrachoa seeds, remove debris and carefully deposit them into a labeled jar or envelope.

Alternatively, transfer the seeds to the container by tapping them onto folded paper. For propagation, ensure a dry, dark, and cold storage environment until early spring.
