The feijoas look fine after the 8f event, no obvious leaf damage. The mulch around my trees and being up against the shed structure has kept the soil from freezing. Everywhere else the ground is frozen.

However the cold did zap my Yuzu leaves, and the poncirus hybrids (tai-tri and citrumelo) leaves are curled up as well. Those are growing against a brick wall and are mulched so the soil didn't freeze. No obvious freeze damage on trunk or stems yet (like splitting) on the citrus or feijoas.

I am at the border of zone 6- 7 and have 3 feijoa plants but i didnt had the guts to plant them in the ground. Lowest so far was -11 C, i may find a place in the yard for one of them this spring. I have read that they lose their flower buds at temps of around -6C or so, is that true? If so even if the plant survives it may be cropless in climates like mine....

I did read that flower buds are killed, but I also read from another account that they make flower buds on new growth in the spring flush

It's been several days and I see no damage after 8f (-13.3C). No leaf drop or noticeable freeze damage on the leaves or trunks

Great news, they give most of them a hardiness to about -15 C ,i was always sceptical but it may be true. I have one feijoa that is rootbound in a pot and will try to find a place for it in the ground comd spring.

shiro:
In my area, some people cut the feijoa tree into balls every year. This way, if ever there is a cold spell, it is easy to put a transparent winter cover over the trees. This also protects the flower buds. But in my case, this pruning is more for the sake of beauty, because cold temperatures of -15C are very rare or of very short duration. I'll post you some pictures when I go for a walk.  But don't worry, they're pretty tough, mine can easily withstand -12C without damage. And even once -20C but only for a few hours, but on already mature trees. But if it didn't die, there was damage that time.
