How hardy are hostas?

Down to -25 ° C - that's the minimum!

The majority of hostas originate from Japanese forest regions. They tolerate frost with flying colors. In this country they are considered to be very hardy. In unprotected locations, most hostas can cope with temperatures down to -20 ° C. In sheltered locations, they can cope with temperatures down to -25 ° C. However, this is their bare minimum!

Some hostas prefer to protect them from the freezing cold

But not all hostas are guaranteed to survive the winter time without damage. Specimens newly planted in autumn should be protected in the first winter as they have not yet had time to take root. Even hostas that are in the pot on the balcony or roof terrace, for example, require winter protection.

For Potted plants A protective layer of fleece and a location on the house wall can be helpful. For example, hostas in the open ground are protected with the following materials:

• Bark mulch
• compost
• Fir branches
• Layer of foliage

The foliage serves as winter protection

Even your own foliage can do it Wintering of the hostas take over. To do this, you should not cut off the withered leaf dress in autumn. Leave it on the plant. It will eventually fall off and cover the root area. It will turn brown and possibly Muddy, but it has a frost protection function for the hosta.

Remove old parts of the plant after winter and take care of them well

When winter time has passed, the hostas will look 'old' if you don't pay any attention to them. Hence it is said:

• Remove winter protection (by April at the latest)
• pour more again
• completely cut off or remove old parts of the plant (usually most of it is rotted)
• fertilize with compost or with potted plants with liquid fertilizer
• before the new shoots like share and multiply
