When you prune your snapdragons is an equally important step as doing the pruning correctly, since the season and temperature outside can change how much you need to prune your snapdragons.
Expert gardener, Drew Swainston at Homes & Gardens advises, 'Snapdragons are usually grown as annuals so the main form of pruning required is deadheading throughout the summer blooming period. This will encourage the plant to put out new blooms and prolong the flowering period for as long as possible. Identify a spent flower head and follow it back down the stem, snipping it off above a healthy set of leaves.'
Zahid Adnan, Founder of The Plant Bible suggests: 'The ideal time to prune snapdragons is in late spring or early summer when the plants have finished their initial flush of flowering. This timing allows them to recover and produce new growth before the next blooming cycle. It's important to note that snapdragons are often grown as cool-season annuals or biennials, so pruning in late summer or fall may not be necessary if they will be replaced in the next season.'
Jacky Chou advises, 'Avoid heavy pruning in fall or winter, as snapdragons need their foliage to protect them from cold temperatures.'
