Petunias are a favorite among gardeners and flower enthusiasts because of their stunning blooms. These summer bloomers come in a variety of colors and are perfect for beds, borders, and containers.
However, sometimes our petunias can fail to bloom, leaving us feeling frustrated and unsure of what to do. In this article, we will explore the reasons why petunias may not be blooming and learn how to make them bloom again.
Reasons for petunia not blooming
Poor lighting
One of the reasons why petunias fail to bloom is due to poor lighting. Petunias require a certain amount of light to bloom, but too much or too little can prevent them from flowering.
Petunias thrive in direct sunshine or full sun for at least six hours per day, so make sure they are placed in an area that receives the right amount of sunlight. If your petunias are growing in a lightly shaded area, consider thinning or trimming surrounding trees or shrubs to allow more light to penetrate.
Wrong fertilizer
Using the wrong fertilizer can also prevent petunias from blooming. Petunias are drought tolerant and prefer a moist but well-draining soil.
However, they require specific nutrients to flower. Liquid fertilizer is an excellent choice for petunias, but make sure it is high in nitrogen and phosphorus.
Bone meal is another great option, as it contains the right amount of phosphorus for blooming. Use a 3-digit fertilizer ratio, such as 10/30/10, to provide the right nutrients to your petunias.
A balanced fertilizer with a high phosphorous number can also help your petunias bloom.
