Guide for prolonging petunia blooms: specialist advice for optimal results
Petunias are beloved for their vibrant and colourful blooms, but to keep them looking their best, it's essential to practice regular deadheading. This straightforward process involves removing spent blooms from the base of the flower stem, encouraging the plant to focus its energy on producing more flowers.
To properly deadhead petunias, follow these step-by-step instructions:
1. Identify Spent Blooms: Look for faded, wilted, or dying flowers on your petunia plant. 2. Pinch or Cut Off Spent Flowers: Using your thumb and forefinger, pinch off the spent blooms just above a leaf node or where you see a new side shoot forming. Alternatively, use clean pruning shears or scissors for a cleaner cut. 3. Cut Above a 5-Leaf Junction: When trimming, cut just above the junction where five leaves meet to encourage healthy new growth. 4. Remove the Entire Flower Stem: If the bloom stem is spent, cut it back along with any faded buds to redirect the plant's energy from seed production to making more flowers. 5. Regular Maintenance: Deadhead petunias every few days or at least weekly during the flowering season to maintain continuous blooming.
In addition to deadheading, it's crucial to pinch back leggy growth about every 4-6 weeks to promote bushiness and fresh flowers. Regular feeding with a balanced fertilizer every 2-4 weeks supports heavy feeding needs and abundant blooms. Watering at the base helps prevent disease, and using protective gloves during deadheading prevents injury.
Some modern petunia varieties, such as Supertunias and Superwaves, are self-cleaning and require less deadheading effort, as their spent blooms drop off naturally. However, regular deadheading can boost overall appearance and flower production, even for self-cleaning varieties.
Petar Ivanov, a gardening expert at Fantastic Gardeners, recommends carrying a small container or bag to collect spent blooms and cleaning snips regularly to prevent disease spread. Jane Dobbs, the lead gardener at Allan's Gardeners, has been responsible for building and maintaining stunning outdoor spaces for over a decade. She advises against common mistakes such as removing faded petals, damaging the plant, leaving the seed pod, delaying the process, over-pruning, and deadheading large healthy sections.
By following these guidelines, you can encourage petunias to continuously produce vibrant blooms throughout the growing season. Happy gardening!
