A few horned violets are sensitive to frost. Even in cooler locations and when grown in pots, overwintering is not a mistake. But how does that happen?
How do you overwinter horned violets correctly?
To overwinter horned violets, cut them back in autumn and cover them outdoors with compost, leaves or brushwood. When grown in pots, they should be overwintered frost-free, e.g. in the cellar. After 2 years it is recommended to reseed the plants.
Covering horned violets outdoors
Horn violets that are not hardy are overwintered outdoors as follows:
- cut down in autumn
- spread a layer of compost, leaves or brushwood over the plant
- Remove winter protection from the end of February/beginning of March
Overwinter horned violets in pots
Many plant lovers plant their horned violets in a pot and put it on the balcony. In this case, overwintering in a frost-free basement is absolutely necessary, otherwise the pot and thus the roots will freeze.
Tips & Tricks
It is not always worth overwintering horned violets. If horned violets have been in the location for 2 years, it is very likely that they will die in the coming year or will only bloom sparsely. It is better to reseed the plants instead of overwintering them.
