Snapdragons are commonly grown as flowering annuals and do not require winter care. Snapdragons can be grown as short-lived perennials in more mild climates, though from zones 7-11. Snapdragons are cool season flowers and they can withstand cold temperatures and light frosts and can therefore last into late fall or early winter.
Protecting Snapdragons in Winter
In milder climates, mulching will protect your snapdragon roots over winter. Over winter there will be no foliage above ground so there is no concern about 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 containers.
Watering Snapdragons in Winter
Snapdragons do not require much water during the winter dormant period. Winter precipitation should be adequate to keep wintering snapdragons watered. Container pots that have been brought into sheltered areas will need very sparse 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 very occasionally, garden plants should be fine.
