    I know I'm a bit late but I noticed you didn't mention the white sapote in this video. What happened to it? It should be pretty cold tolerant as far as I know.

    It is very useful experiment. I am almost your neighbor(Rosegarden) so I am inspired with your results. Will you have time to post results of another winter behind us?
    I am entirely new in the world of sub/tropicals and I appreciate your experiment. But it goes further…it can influence so many more people or even plant nursery business. Maybe we don’t need to drive to San Diego for our plants.
    Do you have any experience with guavas? My favorite fruits.
    In any case, you do great videos and if you have any time please do continue.

    Lost my El Bumpo (as you are aware of), now I am worried about my Chaffey.

    Last late freeze awhile ago, harmed it (hopefully not too much).

    What is a fair price for a Longan and Starfruit? I'll be in LA later to buy them both. The cheapest I've found are 3 gallon for $60.

    Sorry, you might have mentioned this elsewhere already, but what is the tree with white flowers behind you at 10:05? Thanks!

    Tip Damage:
    Tropic Pink Guava

    Dead:
    Manila Mango

    No frost cover?

    Is there any way you could have prevented the damage?

    Possibly by having taller companion trees to protect from frost and possibly thicker deeper mulch 12-24” deep?

    Curious cuz I live in the bay and am doing research 🙂 thanks!

    i am in zone 9 also (New Orleans)
    and we have very similar winter temps.
    it rarely gets below 28, but, this year one night actually hit 25F
    (coldest ive seen in 10 or 15 years)

    I had similar results…

    cherry of the Rio was not phased at all.
    nor was Feijoa, or Longan… Lychee has minor damage. (all from seed)
    a couple i lost were a few mango, eggfruit, a Cherimoya, a black sapote, neem, Muntingia.
    Acerola was badly damaged, but came back and it grows very fast.
    (its been producing fruit for 2 months and is 7ft tall)
    starfruit (7ft tall) , really wasnt badly damaged, just lost leaves and small twigs.
    now producing fruit normally…

    While several came back, but, i didnt see any growth until June or even July
    i had a huge Mamey 6ft tall+ i thought was dead, came back from the roots in late July.

    Others that came back from roots after May…
    Inga , Cherimoya , Black sapote , mango , Jackfruit

    For me, its worth it to let them grow again, simply because SOME years we dont get any frost
    or, its very light and only 1 or 2 nights
    trees might loose leaves, but regrow them in early spring.
    my largest mango was fruiting size and died back to the roots
    BUT…
    its already 7ft tall, and if i get 2 or 3 years in a row with temps over 30ish
    its possible the tree will get much larger and able to handle frost.
    i have similar hopes for Inga, Jackfruit and Black sapote.

    My Inga was about 3ft tall, and came back from the roots in July
    its now 6ft tall and wide.
    If we have a "normal" winter, i suspect i will loose some smaller branches
    but the main trunk and larger branches should stay intact.
    and it grows so fast it could be 10-12ft by end of 2018.

    I knew there is someone out there conducting this experiment. So many survivors but I was disappointed to see the results for sapote. Mango is a fussy plant to grow even in India, so I was not expecting anything different.

    Been waiting for the fall video. Are we going to see one before winter sets in ? If you are not going to make any videos (would be a shame) please say so.

    I'm going to leave my Kari Starfruit, Tropic Pink Guava, Kohala Longan, and Soursop by the fence, surrounded by Jaboticaba and Red Jaboticaba, out in the open this coming Winter. Any summer update with your trees Joe?

    Joe, I just got a starfruit tree from fast growing trees, can plant on the ground right now?

    Hey dude, it's fall. How did your tree experiment do this year?

    In San Jose in bay area, cherimoya trees don't need cover. Same goes with longan and it fruits.

    I bet- the Mangoes that held leaves look pretty good by now -September? I mean,you started with tree's you never see that size for sale in the bay area. Most are 3' Manila's.

    The key to Mango is,you MUST protect from frost the first two winters. They cannot take a freeze ( 32f) with winter rains when they are still in that twiggy growth in the bay area. After that with 3 years in ground more or less? They are a different animal. A single 32f..singes just a few leaves not burns to death. You started with hefty tree's…I would have covered and heated the first winter on our usual-1-3days of frost. Makes a huge and gigantic difference. Mangoes grown here get very sweet. Worth it.

    You should try strawberry guava it should be cold hardy any where in zone 9b (hardy to 22F)

    Great idea Joe and thanks for making these videos on your experiment. I had a similar idea for my yard (San Diego) and wasn't sure what would work so I decided the shotgun method might be a quick way to figure out what works and what doesn't. I was intrigued by the idea of micro climates since home gardeners aren't planting an orchard they can plant in that special warm nook on the south side of the house. Right now I'm growing an array of Cherimoyas (El Bumpo + seedlings), Sour Sop, White Sapote, a Mexican Guava, Pineapple Guava, and Surinam Cherry. I have 4 baby Miracle Berry plants in the mail for taste tripping. One possible outcome is that you'll get trees but no fruit because of the climate mismatch.
