Snapdragons are commonly grown as flowering annuals and are usually discarded at the end of the growing season. Snapdragons can be grown as short-lived perennials in more mild climates, including zones 7-11. Snapdragons are cool-season flowers that can withstand cold temperatures and light frosts; thus, they can persist into late fall or early winter.
Protecting Snapdragons in Winter
In milder climates, mulching will protect your snapdragon roots over winter. In the winter, snapdragons will not have foliage above ground, so there is no concern about foliar damage.
Cutting Back Snapdragons For Winter
Snapdragons should be cut back to the ground after the end of their blooming season. Spent flower stalks can be composted. In colder climates where snapdragons do not overwinter, seed pods can be saved for sprinkling in the spring.
Snapdragon Winter Care in Pots
Snapdragons make wonderful container plants. In mild climates, snapdragon containers can be brought into a garage or other sheltered location to help overwinter the plants.
Watering Snapdragons in Winter
Snapdragons do not require much water during the winter dormant period. Winter precipitation should be adequate to keep overwintering snapdragons watered. Containers that have been brought into sheltered areas will need minimal watering once a month or so to be kept alive.
Growing Snapdragons Indoors
Snapdragons will not do well as indoor plants and cannot be grown indoors.
Steps To Care For Snapdragons in Winter
Step 1 - In colder climates, collect seed pods for spring sowing.
Step 2 - In more mild climates, cut back spent snapdragons to the ground at the end of the growing season.
Step 3 - Mulch plants with a thin layer to insulate during the winter.
Step 4 - Move container snapdragons into sheltered locations.
Step 5 - Water containers sparingly, and garden plants should be fine.
