Deadheading petunias refer to a pruning method that aims at extending the period that your flowers will produce blooms, making your plant to look healthier, and increase the number of blossoms. Cutting of the dying and dead blossoms will prevent seed maturity that occurs in the green portions under the blooms. Even though the flower will die, the green portion left behind will give seeds not unless you eliminate it alongside the blossom. This procedure will take several minutes or hours depending on the number of petunias you have. You will realize better results when your petunias grow in small containers than when they grow on a large garden.

Deadheading also prevents seed formation. Petunias will outgrow their space if they are allowed to self-sow. Since this plant grows differently in separate climatic conditions, one gardener’s invasion can be the other one’s challenge. Deadheading will also encourage the plant to set more flower buds. Plants usually flower to set seeds but if the flowers are removed before maturity into seeds, petunias will end up growing into more flowers. Petunias will continue growing throughout the growing season if deadheaded. They will keep repeating bloom through the season. Your garden will keep looking colorful and fresh at all times.
