Bayarea, Northern California winter survival report

[jbaqai]

This was one of the odd winter in the history of bayarea (or California), it rain like crazy in one week of nov, and then no rain till the mid week of feb

And also there was 1 or 2 week in the month of dec where it really cold, it was around 27° F

I had that cheap green house that I put to protect from the wind. With busy life, this is what I was willing to do, and wanted to see which cultivar will survive

Greenhouse
http://www.amazon.com/gp/aw/d/B0037QGR6K?vs=

So putting the results out there for the people in the same climate can benefits from it

Mango
Pickering 3 gal :-  dead to the roots
Carrie 3 gal.      :- dead to the roots
Nam doc mai 7gal  :- totally untouched , not a single leave drop and still have fruit hanging
Mahachanok #1 3 gal :-  totally untouched , not a single leave drop
Mahachanok # 2 7gal :- totally dead , I am real puzzled here, why 7 gal dead, but 3 gal is fine ?
Mailika 3 gal :- all leave drop and branch died back of the top 1ft, sprouting new growth
LZ 3 gal (but the 8ft tall, monster ) :- all leave drop , but first one to sprout, and now heavy growth already , true monster indeed
Keitt 3gal :- minor died back of the top 6 inch, but now flowering
Alphonso 3gal :- all leave drop , died back top 6 inch , now sprouting
Manila seedling :- all leave drop, minor damage to top 6 inch, beginning to sprout   

Sapodilla
Silas Woods :-  the one of the plants which actually grew in the greenhouse
Alano :- untouched , but no new growth

Sugar apple :- leaves drop , I guess that was expected

Java plum : small baby crazy plant , actually grow a lot during the winter

Papaya ( Mexican and solo ) :- both died , victim of fungus , hard to control in green house with humidity

Falsa :- all three baby plant drop leaves (expected) , and now showing sign of sprouting


I think there lots of factor that can effect the outcome , I am pretty sure people might have different results given the circumstances

Thanks

was a little curious. I'm also in Zone 9b Temecula CA where we see 27 degrees every couple years or so. And I also just purchased 11 mango trees. Was wondering how long did it stay 27 degrees throughout the day? also did it drop and colder than 27? what were your watering conditions? Were these plants on south side wall of your home?

This post really scares me.

Longan, lychee, wax Jambu, sugar apple, papaya all dead during the freeze in Dec, it was down to 22 at 5AM , I'm in San Jose area, is it zone 9b? All of mine were just under the arbor, no green house.
Live and learn. I have a green house project this summer.

I've been looking up those pvc pipe green houses...Hopefully I can get something going for cheap.

Clay you may have to put enclosures over the younger mango trees in the ground, when a cold snap comes through. Otherwise risk losing the tree, I heard that mangoprofessor had some colder tolerant mango selections (I have no idea on availability of the mango trees though).

Make sure to take advantage of micro climates with the mango trees. Masonry walls can really help a zone 9b grower with mango trees (the wind break and heat sink properties of it are very nice for the winter time). If you have south facing masonry walls in the backyard, I would dedicate that area to mango trees and your most cold affected plants.

sorry for your lost. and thanks for the report, nam doc mai is on my next mango wanted list, my winter temperature was not as bad as yours and my malika was affected probably due to planting shocks by moving from a 3 gallon pot to 5 gallon air pot, it was putting out new growth, once i planted it in the ground it died back again, luckily its putting out new growth.

Glenn - planted in the ground flowered no fruits set, no new growth. i cut it back again lower to get rid of the old flower spikes. Hope it will bounce back soon.

This is my first time trying to grow mango trees, and thx for the report and hope the best for your trees

There are so many variables that can control the out come. soil, watering schedule , area of planting. so pls take this report as the informative (not as a guide)

but my results are kinda inline to what local nursery LaVerne is selling (like nam do mai, Keitt, etc)

having a structure to protect the plant during the winter season would be consider a wise investment , since this is the first time my manila seedling survived. it didn't survive the two year before this one without the green house.

plus be careful with the watering. I think my carrie died because of over watering via rain in the month of Nov. So fast drain soil is the must if plants are in pot

and i kinda give up on papaya , since this is the third time they died back on me. this time due to fungus invasion , it was really hard to control in the green house .    perhaps bring them indoor during the winter might be the only option ... . will see if i want to take another chance this year. ..
