Snapdragons can repeat bloom throughout the season but they do best in the cool of spring and fall. In cooler climates, they bloom all summer long, and in milder climates, they sometimes bloom throughout the winter. These short-lived perennials are usually grown as annuals.

How do you keep snapdragons blooming?

Caring for snapdragons

To prolong flowering, feed weekly with a potash-rich fertiliser and deadhead spent blooms regularly. Keep plants well watered and support taller varieties with canes if required.

How do you get snapdragons to bloom all summer?

Deadheading will help keep your snapdragons blooming throughout the summer. Remove the faded flowers just below the flower stem and above a set of healthy leaves. This will keep the new blooms coming. If the plant becomes leggy (long stems and few leaves) prune back further along the stem.
