Fatsia spiders web and japonica and gunnera manicata
in Plants
Good morning everyone, Just a quick question about frost hardiness for the above plants. I've always thought fatsias are fairly frost tolerant, but do they have a maximum temperature they can go to in a frosty spell, they are fairly secluded but would suffer a little bit of wind.
Also gunnera manicata I thought can survive down to -12 if the crown is protected? Other people tell me it's much less than that?
They are a first year and second year but have dropped in the frost. Anything I can do to help ?

Thanks 🙏🏻

I have also regarded Fatsia as tender here but further south from me it seems fine.
Sometimes there are exceptions if the microclimate is right for a plant it will survive further north than you would expect.
I am sure there are more Fatsia growers out there who can help, the problem could be your plants are only young. A more mature plant could be more resistant to cold?
In severe winters both can be cut back to the ground but it's unusual for fatsia to be that affected, although they can suffer from winter and take a while to look happy again.
