Calibrachoa, also known as million bells, is a beautiful flowering plant that is popular among gardeners for its vibrant colors and long blooming season. One of the easiest ways to propagate calibrachoa is through stem cuttings, which allows you to create new plants that are genetically identical to the parent plant. However, rooting the cuttings can sometimes be a challenge, and the cuttings can also be prone to rotting if not properly cared for. In this article, we will discuss some tips and techniques to ensure successful rooting of calibrachoa cuttings and prevent rotting.

When taking cuttings from a calibrachoa plant, it is important to select healthy, disease-free stems that are actively growing. Ideally, the stems should be about 3-4 inches long and have at least one pair of leaves. To take the cuttings, use a clean and sharp pair of pruning shears to make a diagonal cut just below a node, which is the point where leaves or buds emerge from the stem. Removing the bottom pair of leaves will help stimulate root growth and prevent rotting.

Tip: It is best to take cuttings in the morning when the plant is well hydrated. This will increase the chances of successful rooting.

After taking the cuttings, immediately dip the bottom inch of the stems in a rooting hormone powder. Rooting hormones contain auxins, which are natural plant hormones that stimulate root development. This will help the cuttings develop roots more quickly and increase their chances of successfully rooting. Make sure to tap off any excess powder before placing the cuttings in a container filled with a well-draining rooting medium, such as perlite or vermiculite.

Tip: It is a good idea to mist the cuttings with water before applying the rooting hormone powder. This will help the powder adhere to the stems more effectively.

Place the container with the cuttings in a warm and bright location, but out of direct sunlight. The ideal temperature for rooting calibrachoa cuttings is between 70-75°F (21-24°C). It is also important to provide high humidity, as this will help prevent the cuttings from drying out. You can achieve this by placing a clear plastic bag or a propagator lid over the container. Just make sure to open the bag or lid for a short period each day to allow fresh air to circulate and prevent mold growth.
