Calibrachoa Aren’t Blooming

Calibrachoa blooms more vigorously during the warm summer months. They bloom best when grown in full sun conditions and when regularly fertilized. Producing hundreds of flowers takes a great deal of energy. As a result, these plants are heavy feeders. Overwatering will cause root rot and stress.

Common Reasons Why Calibrachoa Isn’t Blooming

Calibrachoa needs 6 to 8 hours of sunlight a day to bloom. Move your plant to a sunnier location if it is not blooming. Calibrachoa is a heavy feeder. They need nutrients to be available in the soil to produce blossoms. Fertilize regularly but follow the directions on the package. Do not over fertilize in an attempt to get them to put out even more flowers. Overfertilization burns the roots and stresses or even kills the plant. Calibrachoa also prefers warm weather. They will not bloom consistently in early spring or late fall when the temperature may not be optimal.

Pruning Calibrachoa To Help It Bloom

Trimming your calibrachoa back will encourage a flush of new growth. Trim the plant back if it becomes leggy or if you want the plant to grow into a bushier shape. Prune calibrachoa back in autumn if you live in a warmer climate where it can safely overwinter outdoors. Calibrachoa can survive being nibbled on by garden pests if a few inches of growth remain intact above the soil.

Fertilizing Calibrachoa To Help It Bloom

Calibrachoa requires adequate nutrients to produce flowers. Fertilizer according to the directions on the package during warmer months. Use a balanced, slow-release formulated fertilizer to avoid burning the roots. Do not over fertilize. Too much fertilizer may be more harmful than too little fertilizer. 

Get Calibrachoa To Produce More Blooms

Providing an adequate amount of sunshine is one of the essential requirements for getting a calibrachoa to bloom. This plant needs between 6 and 8 hours of sunlight to produce an abundance of blossoms. Trim your plant back if it has grown leggy, and with adequate sunlight, fertilizer, and the proper temperature range, it should begin blooming again.
