Climbing gloxinias are not really hardy, even if that is more common to read. It's not just the cold that plays a role. Above all, the soil moisture in winter is very hard on the plants. This is how you overwinter a climbing gloxinia properly.

Overwinter Climbing Gloxinia outdoors
If you want to overwinter a climbing gloxinia outdoors, the plant needs a well-protected location where it doesn't freeze if possible. The soil must be well drained to avoid waterlogging.
Cover the ground with mulching material. Before planting, protect the tubers with wire baskets to prevent rats, mice or moles from attacking them.
Set up the bucket frost-free and protected from rain
- Find a wind-protected, frost-free place
- Place bucket on insulating subsoil
- Cover the container with foil or fleece
- Don't keep soil too moist
tips
Like all gloxinia species, the climbing gloxinia is not poisonous. You can take care of them on the terrace or balcony without worrying, even if there are children and animals in the house.
