Thanks Shirlee!! I remeber reading Don's page years ago and have often wondered how his trees were doing.. He is not too far south of me so maybe there is hope for me!!! That is one yard tour I'd love!!!
yet another reason for me to start Central states Citrus grower association.. so we can have Expos and tour Don's place!!! LOL

I live in Fort Smith, AR and I have a friend in OKC. This is only about 2.5 hours from me. I might try putting one of my Meyers in the ground this year to see how it makes it through the winter.

IMHO no chance in zone 7.

The meyer can make it with a lot of love

I am more of a kick in the rump kind of guy. I guess we will see April next year if I am successful.

After Tanaka's and Swingle's classification, I adopted the Nagle classification:
- hard-to-kill citrus
- need-care citrus
- difficult-to-grow citrus
- to-avoid citrus

It has to be crossed with an other classification:
- not edible
- not good taste
- good taste
- very good taste

Indeed, in zone 8b one can expect a 'good-taste' in the 'need-care' category, but in zone 5 one must be happy to have a 'bad-taste' in the 'hard-to-kill' category...
Speaking of citrus in the field indeed, because indoor, everything is possible.

829, Your Meyer will freeze to the ground every year. As said in the books, it will restart from the root but I don't think it can stand that for years!
I hope I am wrong.

Here I am in zone 8. This year we had - 7°C. I have rows of PT, FD, yuzu, ichang lemons, citremons, Cleopatra mandarins and Meyer seedlings (not true-to-type, I know).
PT, FD, yuzu and ichang lemons are OK.
Citremons are very bad. I hope that some of them will restart from the downside of the stem.
Cleopatra mandarins seem all dead.
Meyer seedlings lost their leaves but the stem is still green.

Citremons and Cleopatra mandarins are supposed to be hardy...

well the meyer ( and all the rest) would depend on the protection, sure w/o protection it wouldnt make it

Frank

in the spring I will post mine that did fine in zone 5/6....

Then again ones that lost protectoin and saw 21f didnt do well , but are still alive

btw thanks for all the definitions I look forward to more posts!

Actually, Don has been a member of this forum for a long time. I think (?) he has posted only once. - Millet (1,414-)

The aim was cold hardy selection so I didn't protect them.
A mass selection begins when at least 50 % die. If only one stays alive you won the lottery. If all die, you've lost.

I see your point.

Sylvain, thanks for the info, I missed the details of your post originally.......apologies


829 what do you mean rock and water?

Thermal radiant heat from rock like flagstone or similar stone and water bags positioned around the tree. I would likely make a tepee from visqueen or other heavy duty plastic covering.
