Feijoa cold hardiness

The feijoas in the Fishsauce image above looked scathed to me.

My large, old bush has dropped perhaps 25% of its leaves. Minimum temperature was 23F. Green leaf drop, either natural or by shaking the branches, counts just cold-damage same as discolored leaves still on the plant.

Any chance you have Sweetcrisp or keecrisp blueberry plants? :laughing:

No. They are dead or dying. I’m ripping them out.

My bar for unscathed is much lower than your. The pic is my potted feijoa and what I would considered as “scathed” :slightly_smiling_face:

On a scathing scale, that is a 10.

My two first year in ground plants lost all their leaves. We had a mild winter for this area, but we had a few days that hit a low of 10 degrees, which is as cold as I ever see it here.

Hopefully they come back this spring.

i have 6 grafted NZ varieties potted plants (3 gallons each, about 2 years old i am guessing from the rootstock) that i had kept outdoors in the low 20s this past winter and they were fine. i only brought them into the garage when it went into the teens one early morning in January when we had snow.

My in ground (1 gallon) New Zealand feijoa planted last spring looked fine through the winter but then dropped their leaves in late March. I think we saw similar low temperature.

What variety is this? Do you think it will regrow from he roots?

They say that a lot of varieties from New Zealand cope better with frost. Maybe yours still need to get more established. Do you know the name of the variety by the way?

They were seedlings I got from Raintree. They survived this winter and I don’t see any suckers coming up from the roots.

I see. I’m impressed by the potted one then. Was it a long duration frost, by the way?

I didn’t protect the potted one with plastic wrapping and it was located in a more exposed area. It saw temp low this winter of 6F. I still see some green near the root when doing a scratch test and hoping that it would come back, we’ll see.

I can look, but all but one of my 3 or 4 New Zealands from the previous year also croaked, but they had a more severe winter and some snow breakage.

I agree that they’d probably be hardier if better established.

That’s severe damage. I hope some of them can still regenerate from the base or something. If the cold temperature lasted for long, it could have gotten to the roots.

I bought some seeds of ‘Nikita’ × ‘Apollo’, hoping they will do great with frosts in the future.
